Rice, Minnesota scientists use predictive modeling to identify optimized zeolites to aid ethanol, petroleum production
January 23, 2015
Scientists at Rice University and the University of Minnesota have identified, through a large-scale, multi-step computational screening process, promising zeolite structures for two energy-related applications: the purification of ethanol from fermentation broths and the hydroisomerization of alkanes with 18–30 carbon atoms encountered in petroleum refining.
The results, presented in a paper published in Nature Communications, demonstrate that predictive modeling of synthetic zeolites—a technique pioneered by Rice bioengineer Michael Deem—and data-driven science can be applied to solve some of the most challenging problems facing industries that require efficient ways to separate or catalyze materials.

UQM Technologies granted patent on permanent magnet electric motor design using non-rare earth magnets
January 20, 2015
UQM Technologies Inc. has been granted a US patent (8,928,198, “Brushless PM machine construction enabling low coercivity magnets”) for an electric and hybrid electric vehicle motor design using non-rare earth magnets. The patent covers the unique magnet geometry and the method of manufacturing the motor.
The majority of electric and hybrid electric vehicles produced today use permanent magnet (PM) motors with rare-earth magnet materials because of the high coercivity of the rare earth materials. Coercivity is a measure of the reverse field needed to drive magnetization to zero after being saturated—i.e., it is a measure of the resistance to demagnetization. The new UQM design enables the use of low coercivity magnets, such as Aluminum Nickel Cobalt (AlNiCo) or Iron Cobalt Tungsten (FeCoW), in PM machines.

Researchers suggest hybrid graphene oxide/cellulose microfibers could supersede carbon fibers
January 16, 2015
Researchers from Nanjing Forestry University and the University of Maryland have designed high-performance microfibers by hybridizing two-dimensional (2D) graphene oxide (GO) nanosheets and one-dimensional (1D) nanofibrillated cellulose (NFC) fibers. The resulting well-aligned, strong microfibers have the potential to supersede carbon fibers due to their low cost, the team suggests in an open access paper published in the journal NPG Asia Materials.
The hybrid microfibers are much stronger than microfibers composed of 1D NFC or 2D GO alone. In their paper, they reported that experimental results and molecular dynamics simulations reveal the synergistic effect between GO and NFC: the bonding between neighboring GO nanosheets is enhanced by NFC because the introduction of NFC provides the extra bonding options available between the nanosheets.

Johnson Controls and its partners are working to reduce the use of metals in vehicle seat structures by replacing them with multi-material systems in the CAMISMA (carbon-amide-metal-based interior structure using a multi-material system approach) research project. (Earlier post.)
The company is displaying the CAMISMA seat prototype, which achieves a more than 40% weight reduction against conventionally manufactured seat structures without compromising safety properties, at the 2015 North American International Auto Show (NAIAS) in Detroit. Johnson Controls received this year’s CLEPA (European Association of Automotive Suppliers) Innovation Award in the “Green” category for this work. According to the jury, the project represents an “outstanding, future-oriented solution for sustainable carbon dioxide reduction.”
Ford puts the pedal down on performance … but not with electric drive technology right now
January 14, 2015
|The new Ford GT on display in the Ford stand at NAIAS. Click to enlarge.|
In December, Ford President and CEO Mark Fields said Ford would focus on five key areas of innovation, one of them being performance. He said that more than 12 new performance vehicles would be introduced through 2020. (Earlier post.) At the North American International Auto Show (NAIAS) in Detroit this week, Ford delivered first proof of that focus with the reveal of the new Ford GT carbon-fiber supercar, as well as the new F-150 Raptor based on the new aluminum F-150 and the Shelby GT350R Mustang.
The stunning Ford GT—which received the EyesOn Design Award at NAIAS for best production vehicle—serves as a technology showcase for top EcoBoost engine performance, aerodynamics and lightweight carbon fiber construction. Beginning production late next year, the GT will the road in select global markets in honor of the 50th anniversary of Ford GT race cars placing 1-2-3 at the 1966 24 Hours of Le Mans. However, unlike today’s hybrid drive Le Mans racers, or the new Acura NSX hybrid supercar, also revealed at NAIAS (earlier post), the GT—nor any of the other Ford performance vehicles unveiled at NAIAS—makes no use of electric drive technology.
ASG life-cycle study finds aluminum Ford F-150 “Best Full-size Truck of 2015” from environmental and economic perspective
According to the latest annual life-cycle study from the Automotive Science Group (ASG), the all-new lightweight aluminum 2015 Ford F-150 leads the full-size light-duty truck competition in all environmental and economic performance areas; accordingly, ASG selected the F-150 as its Best Full-size Truck of 2015. According to ASG and the principles of ecological economics, environmental and economic considerations are equally important in determining a vehicle’s overall value. ASG’s proprietary vehicle rating platform—the Automotive Performance Index—analyzes both performance areas for a comprehensive vehicle assessment. ASG’s 2015 Study assessed 225 light-duty truck models.
Although the gasoline-fueled F-150 with 2.7L EcoBoost delivers 22 mpg (10.68 l/100 km) combined—1 mpg shy of RAM’s EcoDiesel—the F-150’s life-cycle environmental and economic performance “leaves RAM and others in the dust,” according to ASG. According to ASG, the 2015 F-150 holds the smallest life-cycle carbon footprint and lowest cost of ownership of any full-size truck in the North American market today. Ford has produced a lightweight aluminum-intensive truck that costs less and performs better than its conventional truck counterparts over the vehicle’s life-cycle, says Colby Self, managing director of ASG.

University of Tennessee to head $250M advanced composites manufacturing institute; Ford, Honda and Volkswagen members
January 09, 2015
The Department of Energy and a consortium of 122 companies, nonprofits, and universities led by the University of Tennessee-Knoxville will invest more than $250 million—$70 million in federal funds and more than $180 million in non-federal funds—to launch a Manufacturing Innovation Institute for Advanced Composites—the fifth institute to be awarded of the eight national institute competitions launched earlier (earlier post).
The new Institute for Advanced Composites Manufacturing Innovation (IACMI), announced today by President Obama, will focus on advanced fiber-reinforced polymer composites that combine strong fibers with tough plastics to yield materials that are lighter and stronger than steel. While advanced composites are used in selective industries such as aircraft, satellites and cars, these materials remain expensive, require large amounts of energy to manufacture and are difficult to recycle. IACMI is dedicated to overcoming these barriers by developing low-cost, high-production, energy-efficient manufacturing and recycling processes for composites applications.

ORNL teams embeds crown ethers in graphene for increased performance; potential for separations, sensors, batteries, biotech & more
December 28, 2014
|This sheet of graphene contains an array of crown ethers that can strongly bind select guest ions or molecules. Image credit: ORNL. Click to enlarge.|
A team led by the Department of Energy’s Oak Ridge National Laboratory has discovered a way to increase significantly the selectivity and binding strength of crown ethers by embedding them within a rigid framework of graphene. The results, published in Nature Communications, may enable broader use of crown ethers in diverse applications. Their strong, specific electrostatic binding may advance sensors, chemical separations, nuclear-waste cleanup, extraction of metals from ores, purification and recycling of rare-earth elements, water purification, biotechnology, energy production in durable lithium-ion batteries, catalysis, medicine and data storage.
Ethers are simple organic molecules in which an oxygen atom bridges two carbon atoms. When linked together in crown-shaped large molecular rings, they have the ability selectively to incorporate various atoms or molecules within the cavity formed by the ring. The size and shape of the cavity formed within a crown ether molecule confers selectivity for complementary ions and small molecules that fit it, like a lock and key. Crown ethers come in different sizes, so they can accommodate ions of different diameters.
Rice U team uses new computational methodology to identify high capacity MOFs for on-board natural gas storage
December 18, 2014
Researchers from Rice University, Lawrence Berkeley National Laboratory and UC Berkeley have developed a computational methodology to support the experimental exploration of potential high-capacity metal organic frameworks (MOFs) for use in on-board storage of natural gas. The advantages to using MOFs as a storage medium are many and start with increased capacity over the heavy, high-pressure cylinders in current use.
In a paper in the ACS Journal of Physical Chemistry C, they report identifying 48 materials with higher predicted deliverable capacity (at 65 bar storage, 5.8 bar depletion, and 298 K) than MOF-5—the currently best available for the natural gas storage application. The best material identified by the researchers has a predicted deliverable capacity 8% higher than that of MOF-5.
New high-entropy alloy is as light as aluminum, stronger than titanium alloys
December 11, 2014
Researchers from North Carolina State University and Qatar University have developed a new high-entropy alloy that has a higher strength-to-weight ratio that they say is unmatched by any other metallic material. The researchers used mechanical alloying to combine lithium, magnesium, titanium, aluminum and scandium to make a low-density, nanocrystalline alloy (Al20Li20Mg10Sc20Ti30) with an estimated strength-to-weight ratio that is significantly higher than other nanocrystalline alloys and is comparable to ceramics. An open access paper on their work is published in the journal Materials Research Letters.
High-entropy alloys (HEAs) are a new class of multi-component alloy systems in which the design of the alloys is based not on adding to a single base element, but on choosing elements that will form solid solutions when mixed at near-equiatomic concentrations. (Earlier post.) HEAs
Consultancy looks to aggressive weight reduction in major powertrain components for CO2 savings; metal and polymer matrix composites
UK automotive engineering consultancy Drive System Design (DSD) suggests the next breakthrough in CO2 emissions reduction will come from more aggressive weight reduction in major powertrain components. Analysis by the company has identified both near-term and medium-term solutions for the manufacture of items such as transmission casings using advanced composite materials, but favors modern hybrid materials such as metal and polymer matrix composites (MMCs and PMCs) over conventional carbon composite solutions.
Continual pressure on the automotive industry to reduce carbon emissions is leading to weight reduction initiatives throughout the vehicle. Currently, several of the heaviest individual components in the powertrain, such as the main casings for the transmission, are still metal (e.g., aluminum alloys, magnesium alloys and iron) castings despite the widespread use of lighter materials elsewhere on the vehicle.
New Mazda bio-based engineering plastic features high-quality finish without paint; suitable for exterior parts
December 10, 2014
Mazda Motor Corporation, in conjunction with Mitsubishi Chemical Corporation, has developed a new bio-based engineering plastic that can be used for exterior design parts for automobiles. The new plastic will help Mazda to reduce its impact on the environment in a number of ways.
As the plastic is made from plant-derived materials, its adoption will help to curb the use of petroleum resources and reduce carbon dioxide emissions. Furthermore, the material can be dyed and emissions of volatile organic compounds associated with the painting process reduced. Dyed parts made from the bio-based engineering plastic feature a finish of higher-quality than can be achieved with traditional painted plastic. The deep hue and smooth, mirror-like finish of the surface make the newly-developed plastic suitable for external vehicle parts with a high design factor.

November 17, 2014
The US Department of Energy (DOE) Fuel Cell Technologies Office’ (FCTO) 2014 Hydrogen and Fuel Cells Program Annual Progress Report (earlier post)—an annual summary of results from projects funded by DOE’s Hydrogen and Fuel Cells Program—described a number of advances in the field of hydrogen storage.
The DOE Hydrogen Storage sub-program has developed a dual strategy. For the near-term, the focus is on improving performance and lowering the cost of high-pressure compressed hydrogen storage systems. For the long-term, the effort is on developing advanced cold/cryo-compressed and materials-based hydrogen storage system technologies.
Vanderbilt/ORNL team discovers new form of crystalline order that could be attractive for thermoelectric applications
A team of researchers from Vanderbilt University and Oak Ridge National Laboratory (ORNL) has discovered an entirely new form of crystalline order that simultaneously exhibits both crystal and polycrystalline properties, which they describe as “interlaced crystals.”
The interlaced crystal arrangement has properties that could make it ideal for thermoelectric applications. The discovery of materials with improved thermoelectric efficiency could increase the efficiency of electrical power generation, improve automobile mileage and reduce the cost of air conditioning. Writing in the journal Nature Communications, the researchers reported finding this unusual arrangement of atoms while studying nanoparticles made from the semiconductor copper-indium sulfide (CIS), which is being actively studied for use in solar cells.

The engines are fitted to various car models made by VW, Audi, Seat and Škoda. Dr. Lutz Wohlfarth from Volkswagen, and Marcio Lima from KACO were both at the Gala in Detroit to collect the SPE award.
Volkswagen outlines a range of near-term technologies for reducing fuel consumption and emissions; stop-start 2.0, 10-speed DSG
November 11, 2014
Volkswagen presented its latest technologies for reducing fuel consumption and CO2 emissions—which includes the first 10-speed dual-clutch gearbox (DSG)—in an Innovation Workshop for the media at the Ehra-Lessien test track facility near Wolfsburg.
Volkswagen AG has set the goal of becoming the world’s most sustainable carmaker by the year 2018. Compared to baseline figures for 2010, the Group wants to reduce energy and water consumption, waste generation and emissions (including CO2 emissions) by 25% in all of its business areas. (I.e., VW’s “Strategy 2018”, earlier post.) To achieve this, the Volkswagen brand—the highest volume brand of the Group—is counting on electric mobility (zero-emission and plug-in hybrid models); on continually more fuel-efficient combustion engines and gearboxes; progressive lightweight design; aerodynamics; and efficiency “in every conceivable area”.
New Unipiston clutch piston technology in series production; enables better fuel economy
November 06, 2014
Federal-Mogul Powertrain’s new high-modulus injection-molded Unipiston clutch pistons are now in series production at the company’s facility in Chivasso, Italy. The technology was a 2013 Automotive News PACE Award Winner in the process category.
Unipiston is a one-piece, rubber-to-metal bonded piston that hydraulically engages clutches to activate the gearshift. The compact one-piece design reduces the number of leak paths while improving reliability and simplifying assembly, and allows transmission designers more flexibility, including increased clutch apply pressures, higher rotational clutch speeds, and larger diameter clutches. This flexibility enables transmissions with additional clutches to be packaged in a smaller space, while providing improved fuel economy, reduced emissions and enhanced vehicle performance.
Rice University researchers create dual-purpose edge-oriented MoS2 film for energy storage, hydrogen catalysis
November 03, 2014
The Rice lab of chemist James Tour has turned molybdenum disulfide’s two-dimensional form into a edge-oriented nanoporous film that can catalyze the production of hydrogen or be used for energy storage as part of a supercapacitor device.
The versatile chemical compound, classified as a dichalcogenide, is inert along its flat sides; however, previous studies determined the material’s edges are highly efficient catalysts for hydrogen evolution reaction (HER), a process used in fuel cells to pull hydrogen from water. Tour and his colleagues found a cost-effective way to create flexible films of the material that maximize the amount of exposed edge and have potential for a variety of energy-oriented applications. A paper on the research appears in the journal Advanced Materials.

GMZ Energy develops new thermoelectric material with lower raw material costs, higher power output; Hafnium-free p-type half-Heusler
October 21, 2014
Researchers at GMZ Energy, a provider of nano-structured thermoelectric generation (TEG) power solutions for mobile and stationary waste-heat recovery (earlier post), with their colleagues at the University of Houston and Bosch, have developed a new Hafnium-free p-type half-Heusler material which offers substantially lower raw material cost than conventional half-Heusler materials. The material also features enhanced performance and mechanical strength due to GMZ’s patented nanostructuring process.
As presented in a paper published in the RSC journal Energy & Environmental Science, the new material improves thermoelectric power output compared to a conventional Hafnium-based product. Further, by replacing the costly Hafnium element with GMZ’s proprietary formulation, the overall cost-per-watt of the TEG is lowered. Cost reduction is beneficial for vehicle and industrial waste heat recovery applications, the developers noted in their paper.
NIMS team develops new magnetic compound with lower neodymium content
October 20, 2014
A research group led by Dr. Kazuhiro Hono at Japan’s National Institute for Materials Science (NIMS) has synthesized a new magnetic compound which requires a lower amount of rare earth element than the currently used neodymium iron boron compound.
The ratio of neodymium, iron and nitrogen in the new compound (NdFe12N is 1:12:1). Its neodymium concentration is 17% of the entire mass compared to 27% for the neodymium iron boron compound known as Nd2Fe14B, the main component used in the strongest permanent magnets. Furthermore, the intrinsic hard magnetic properties of the new material were found to be superior to those of Nd2Fe14B.
Industry report says steel can deliver weight savings to meet CAFE targets; aluminum growth in LDVs to peak around 2018
October 06, 2014
Steel can easily deliver the weight savings required to meet federally mandated fuel economy targets for most vehicles, according to a new 300-page analysis by the steel-industry information service World Steel Dynamics: “AutoBody Warfare: Aluminum Attack.” The report, based on WSD’s independent consultation with steel, aluminum and automotive experts, is formally being presented to steel executives today at the worldsteel Annual Conference in Moscow.
The report, say the authors, comes in the context of the “high-stakes contest” between the world’s leading steel and aluminum companies instigated by the rise in the US Government’s CAFE standards. Aluminum companies are in an “ebullient mood”, WSD says, due in part to the aluminum-bodied 2015 Ford F-150 (earlier post) and an Aluminum Association report, authored by the Ducker Worldwide consulting group, forecasting that by 2025 three-in-four pickup trucks will have an all-aluminum body. (Earlier post.)

Researchers propose new class of high-temperature alloy; eutectic high-entropy alloys with both high ductility and high strength
August 29, 2014
High-entropy alloys (HEAs), which represent an emerging effort in materials science and engineering, are multi-principal-element (at least four) alloys that are promising for high-temperature applications due to their high resistance to softening at elevated temperatures and sluggish diffusion kinetics.
However, HEAs so far have either high strength or high ductility; achieving both has been a challenge. Further, the inferior castability and compositional segregation of HEAs have been obstacles for commercialization. Now, researchers in China are proposing a new strategy for designing high-entropy alloys using the eutectic alloy concept to accomplish both attributes. As reported in a paper in Nature’s open access journal Scientific Reports, an eutectic high-entropy alloy (EHEA) showed an “unprecedented” combination of high tensile ductility and high fracture strength at room temperature. The excellent mechanical properties could be kept up to 700 °C.
Johnson Controls invests in IHU-TUT project to combine aluminum and steel in laser-welded tailored tubes for seats
August 27, 2014
Johnson Controls is investing in a German automotive research project working to combine steel and aluminum in laser-welded tailored tubes for use in seats for the first time. The result could be a 10 to 20 percent reduction in weight, which would be beneficial for fuel and emissions balance.
Tailored tubes are already used to a great extent in the large series production of vehicle seats, but in this project, they consist of steel and aluminum of various wall thicknesses. As part of the research project “Hydroforming of laser-brazed tailored hybrid tubes of a steel-aluminum blend for automotive lightweight construction” (Innenhochdruckumformen laserstrahlgelöteter Tailored Hybrid Tubes aus Stahl-Aluminium-Mischverbindungen für den automobilen Leichtbau, IHU-TUT), which runs until 31 January 2016, the project partners are researching the opportunity to make use of the significant weight advantages of aluminum by combining it with steel in the hollow components.

Only 6 will be built. Car Zero has been completed and, on 14 August, will be revealed at the opening reception to the Pebble Beach Automotive weekend. Jaguar announced in May 2014 that it would recreate six new Lightweights, each built by Jaguar Heritage, part of Jaguar Land Rover’s new Special Operations division.
In recreating the Lightweight, Jaguar Heritage has drawn on Jaguar’s engineering and design resources, including the company’s aluminum body technology. The specification includes an aluminum bodyshell with doors, trunklid, hardtop and hood also in aluminum. The six-cylinder XK engine mirrors the original power units, with an aluminum block, wide-angle aluminum cylinder head and dry sump lubrication.
Mercedes-Benz to use new steel pistons in V6 diesel of E 350 BlueTEC
August 11, 2014
Mercedes-Benz will replace conventional aluminum pistons with a new generation of steel pistons in the V6 diesel engine of the E 350 BlueTEC in September. Combined with the innovative NANOSLIDE (earlier post) cylinder bore coating technology and the aluminum housing, the advantages of the shift include lower fuel consumption and CO2 emissions.
Mercedes-Benz has already announced the coming use of steel pistons in the OM 626 four-cylinder diesel produced by Renault and applied in the C-Class Estate. (Earlier post.)

In recent years, field inspectors in nine states have reported many rapidly corroding underground gasoline storage tank (UST) components such as sump pumps. These incidents are generally associated with use of gasoline-ethanol blends and the presence of bacteria, Acetobacter aceti, which convert ethanol to acetic acid, a component of vinegar. Corrosion can result in failures, leaks and contamination of groundwater, a source of drinking water.
Following up on the inspectors’ findings, a National Institute of Standards and Technology (NIST) laboratory study has demonstrated severe corrosion—rapidly eating through 1 millimeter of wall thickness per year—on steel alloy samples exposed to ethanol and acetic acid vapors. Based on this finding, NIST researchers suggest gasoline stations may need to replace submersible pump casings, typically made of steel or cast iron, sooner than expected.
Jaguar: aluminum-intensive XE will feature fuel consumption lower than 4L/100km; structure is 75% aluminum
July 29, 2014
|The aluminum body of the XE. Click to enlarge.|
In the second of four technology previews leading up to the introduction of the new Jaguar XE on 8 September, Jaguar outlined its extensive use of aluminum in the new model. Designed around Jaguar’s modular vehicle architecture, the XE is the only car in the class to use an aluminum-intensive monocoque, with lightweight aluminum accounting for 75% of the structure.
The new aluminum-intensive SE will be paired with engines from the new Ingenium family of efficient diesel and gasoline engines (earlier post)—powertrains specifically designed and calibrated to complement reduced-weight vehicles. Jaguar projects that the resulting XE will achieve fuel consumption of less that 4.0 l/100 km (59 mpg US) on the NEDC combined cycle (subject to certification) and CO2 emissions of less than 100 g/km.
SABIC’s polycarbonate rear window in Ford MMLV reduces window weight by 35%; improved thermal insulation
July 17, 2014
Among the technologies Ford incorporated into its drivable multi-material lightweight vehicle (MMLV) (earlier post) is an advanced polycarbonate (PC) glazing solution from SABIC’s Innovative Plastics business that makes possible a 35% weight reduction compared to the same window on a 2013 model year Ford Fusion production vehicle. The weight savings total 7.4 pounds (3.36 kg), even though the rear window is more than one millimeter thicker than the production glass window it replaces. The PC material has approximately half the density of glass.
The advanced PC solution used in the concept’s rear window combines LEXAN resin, a PC material characterized by its light weight, high optical clarity and impact resistance, with EXATEC E900 plasma coating for glass-like scratch and UV resistance. (The LEXAN plasma-coated windows are also used in Volkswagen’s ultra-efficient XL1 plug-in hybrid, earlier post.)

Under a new 10-year, $1.1-billion agreement, Alcoa will supply key parts for Pratt & Whitney’s jet engines, including the forging for the first aluminum fan blade for jet engines. The forging was developed for Pratt & Whitney’s PurePower engines using an advanced aluminum alloy and a proprietary manufacturing process. Also for the PurePower engines, Alcoa is developing a fan blade forging using its most advanced aluminum-lithium alloy.
Under the $1.1 billion deal, Alcoa will supply components for Pratt & Whitney’s PurePower PW1000G, V2500, GP7000 and several other regional jet and military engines. The unique Geared Turbofan architecture of the PurePower engine allows for aluminum alloys to be used in the Pratt & Whitney designed fan blades, making the engine lighter, as well as more fuel and cost efficient.
Bio-inspired gradient structure approach for delivering stronger, tougher metals
July 12, 2014
Drawing inspiration from the structure of bones and bamboo, researchers at the Chinese Academy of Sciences (CAS) and North Carolina State University have found that by gradually changing the internal structure of metals to a gradient structure (GS), they can make stronger, tougher materials that can be customized for a wide variety of applications—from body armor to automobile parts.
In a pair of open access papers, one published in the Proceedings of the National Academy of Sciences (PNAS), the other in Materials Research Letters, the researchers, led by Yuntian Zhu at NC State and Xiaolei Wu at CAS, report that gradient structures in engineering materials such as metals produce an intrinsic synergetic strengthening, which is much higher than the sum of separate gradient layers; the gradient structure renders a unique extra strain hardening, which leads to high ductility.
Researchers develop efficient technique to develop new materials with desired coefficient of friction
July 11, 2014
Researchers at Japan’s National Institute for Materials Science (NIMS) have developed a highly efficient method for developing friction materials with a desired frictional property. Using the new method, it would be possible to find the appropriate crystal preferred orientation for coatings with the desired value of the coefficient of friction.
The method, described in a paper in the journal Tribology Letters, could thus significantly accelerate the development of materials that have a friction coefficient suited to the purpose of use, such as low-friction materials for reducing energy loss and high-friction materials required for high-performance brakes.
European consortium investigating graphene-based materials for lightweight cars; energy-efficient and safe vehicles
June 30, 2014
The University of Sunderland (UK), working with a consortium of five other research partners from Italy, Spain and Germany, has been selected for funding by the €1-billion (US$1.4-billion) Graphene Flagship research initiative in Europe (earlier post) for their iGCAuto proposal. The researchers will explore the properties of graphene to determine how it behaves when used to enhance advanced composite materials used in the production of cars. The other partners are Centro Ricerche FIAT (Italy); Fraunhofer ICT (Germany); Interquimica (Spain); Nanesa S.r.l. (Italy); and Delta-Tech S.p.A. (Italy).
As part of the work, a novel graphene-based polymer material will be investigated, modeled, and designed to enhance both vehicle and occupant safety while remaining very light. This material will provide benefits such as improved strength, dimensional stability, and superior durability.
LLNL/MIT team creates ultralight, ultrastiff metamaterials; possible applications for automotive and aerospace
June 20, 2014
Researchers at Lawrence Livermore National Laboratory and Massachusetts Institute of Technology (MIT) have developed materials with the same weight and density as aerogel (“frozen smoke”) but with 10,000 times more stiffness using additive micro-manufacturing processes. The research team’s findings are published in an article in the journal Science.
The micro-architected metamaterials maintain a nearly constant stiffness per unit mass density, even at ultralow density. This performance derives from a network of nearly isotropic microscale unit cells with high structural connectivity and nanoscale features, the structural members of which are designed to carry loads in tension or compression, the researchers said. Materials with these properties could someday be used to develop parts and components for aircraft, automobiles and space vehicles.
The technology behind Ford’s Lightweight Concept Vehicle; prospects for Mach-II with 50% mass reduction difficult
June 18, 2014
Earlier this month, Ford unveiled its Lightweight Concept vehicle, which uses advanced materials to explore future weight-reduction solutions that could improve performance and fuel efficiency while reducing CO2 emissions. The Ford Lightweight Concept reduces the weight of a 2013 Fusion to that of a Ford Fiesta, resulting in a nearly 25% weight reduction. (Earlier post.)
The Ford vehicle is based on the first phase (Mach-I) of work of the DOE-supported Multi-Material Lightweight Vehicles project (Award DE-EE0005574) by Vehma International (an engineering and prototype division within the Cosma International operating unit of Magna) and Ford. The $20.3-million project ($10 million from DOE, $10.3 million from Vehma/Ford) has two main objectives. First, to design and build the “Mach-I” prototype vehicle maintaining donor vehicle architectural space and using commercially available or demonstrated materials and processes while delivering a 22% reduction compared to the baseline vehicle. The result of this is reflected in the Ford concept.
Washington State/Boeing SOFC shows promise for aviation and automotive applications
June 17, 2014
|MoO2-based SOFC using a fuel mixture consisting of n-dodecane, CO2 and air. Kwon 2013. Click to enlarge.|
Researchers at Washington State University, with colleagues at Kyung Hee University and Boeing Commercial Airplanes, have been developing liquid hydrocarbon/oxygenated hydrocarbon-fueled solid oxide fuel cells (SOFCs) for aviation (the “more electric” airplane) and other transportation applications, such as in cars. These fuel cells first internally—i.e., no external reformer—reform a complex liquid hydrocarbon fuel into carbon fragments and hydrogen, which are then electrochemically oxidized to produce electrical energy without external fuel processors. The SOFCs feature a MoO2 (molybdenum dioxide) anode with an interconnecting network of pores that exhibit excellent ion- and electron-transfer properties.
In a new paper in the journal Energy Technology, the team reports that this novel fuel cell, when directly fueled with a jet-A fuel surrogate (an n-dodecane fuel mixture), generated an initial maximum power density of 3 W cm-2 at 750 °C and maintained this high initial activity over 24 h with no coking. The addition of 500 ppm of sulfur into the fuel stream did not deactivate the cell.

June 10, 2014
|NA aluminum sheet demand for auto body and closure parts. Click to enlarge.|
By 2025, more than 75% of all new pickup trucks produced in North America will be aluminum-bodied, according to a survey of automakers conducted by global consulting and research firm Ducker Worldwide and commissioned by The Aluminum Association’s Aluminum Transportation Group (ATG). The study surveyed all major automakers and forecasts that Ford, General Motors and Fiat Chrysler will become the biggest users of aluminum sheet in the next decade.
It also forecasts that the number of vehicles with complete aluminum body structures will reach 18% of North American production, from less than 1% today. Vehicle segments revealed as emerging aluminum content leaders are pickup trucks, sport-utility vehicles (SUVs) and both mid-sized and full-size sedans.

IBM Research discovers new class of industrial polymers; cheaper, lighter, stronger and recyclable thermosets for aerospace, automotive and others
May 16, 2014
Using a novel computational chemistry hybrid approach, scientists from IBM Research have successfully discovered a new class of polymer materials—the first new class of polymers discovered in more than 20 years—that could potentially transform manufacturing and fabrication in the fields of transportation, aerospace, and microelectronics. The new family, formed by condensation of paraformaldehyde with bisanilines, can form hard thermoset polymers or, when more oxygenated, produce self-healing gels.
Developed by combining high performance computing with synthetic polymer chemistry, these new materials are the first to demonstrate resistance to cracking; strength higher than bone; and the ability to reform to their original shape (self-healing), all while being completely recyclable back to their starting material—strong acid digestion allows the recovery of the bisaniline monomers.

Due to the high demand for carbon fiber in automotive production, SGL Automotive Carbon Fibers, a joint venture between the BMW Group and the SGL Group, will triple the capacity of the carbon fiber plant in Moses Lake, Washington. SGL and BMW made the announcement at the groundbreaking ceremony for the planned site expansion. The expansion will be funded by an investment of US$200 million, on top of the previously invested US$100 million.
The site expansion, scheduled to be completed by early 2015, will make the plant in Moses Lake the world’s largest carbon fiber plant. At present, the Moses Lake plant operates two production lines, exclusively for BMW i, with an annual output of approx. 3,000 tons of carbon fiber. The expansion of the site in Moses Lake will make it possible for the BMW Group to apply carbon fiber material also in other model series in the future, at competitive costs and in large quantities.
Ames Lab researchers observe rare-earth-like magnetic properties in iron
April 29, 2014
Scientists at the Department of Energy’s Ames Laboratory have observed magnetic properties typically associated with those observed in rare-earth elements in iron, albeit at cryogenic temperatures. These properties are observed in a new iron-based compound that does not contain rare earth elements, when the iron atom is positioned between two nitrogen atoms.
The discovery opens the possibility of using iron to provide both the magnetism and permanence in high-strength permanent magnets, such as those used in direct-drive wind turbines or electric motors in hybrid cars. The results appeared in Nature Communications.
Magnesium alloy VSC Machine successfully begins trial operation at GM China Advanced Technical Center
April 04, 2014
|Magnesium alloy VSC machine. Click to enlarge.|
The GM China Advanced Technical Center (ATC) in Shanghai announced the operation of its magnesium alloy Vertical Squeeze Casting (VSC) machine—the first designed for developing next-generation magnesium castings. GM said that this achievement marks a breakthrough in its lightweight materials research.
Squeeze casting is a process in which molten metal is introduced to casting cavities with minimum turbulence and then solidifies under very high pressure (typically above 100 MPa) within closed dies. The absence of turbulent metal flow, aided by the high applied pressure, can suppress gas porosity, notes Ohio State University Professor Alan Luo in a 2013 review of magnesium casting technologies.
Heat-conducting polymer cools hot electronic devices at 200 °C; potential for automotive applications
March 31, 2014
A team led by researchers from Georgia Tech have used an electropolymerization process to produce aligned arrays of polymer nanofibers that function as a thermal interface material able to conduct heat 20 times better than the original polymer. (Polymer materials are usually thermal insulators because the amorphous arrangement of the molecular chains reduces the mean free path of heat-conducting phonons.) The modified material can reliably operate at temperatures of up to 200 °C.
The new thermal interface material could be used to draw heat away from electronic devices in servers, automobiles, high-brightness LEDs and certain mobile devices. The material is fabricated on heat sinks and heat spreaders and adheres well to devices, potentially avoiding the reliability challenges caused by differential expansion in other thermally-conducting materials. A report on the work is published in the journal Nature Nanotechnology.
Toyota and partners develop vehicle-to-vehicle copper recycling technology
March 25, 2014
|Sample vehicle wiring harness. Click to enlarge.|
Toyota Motor Corporation (TMC) has developed a world-first technology for recycling the copper contained in wiring harnesses, in collaboration with Yazaki Corporation (Yazaki), Toyota Tsusho Corporation (Toyota Tsusho), and eight other companies. The newly-developed technology produces copper with a purity of 99.96%.
Roughly 40 years’ worth of mineable copper resources remain worldwide, according to a 2013 report by Japan Oil, Gas and Metals National Corporation (JOGMEC). At the same time, global consumption is growing, driven particularly by infrastructure-related demand for wiring in emerging markets. In addition, large amounts of copper are used in the motors of hybrid vehicles, which are becoming increasingly popular.
GM uses lightweight, advanced materials to reduce weight on 2015 Colorado pickup
March 17, 2014
|Mass comparison, 4x4 crew cabs. Click to enlarge.|
The 2015 Chevrolet Colorado uses engineering techniques and lightweight materials to create fuel-efficient pickup capability in a mass-efficient mid-size package. The 2015 Colorado 4x4 crew cab, which GM expects to be the most popular version of the new trucks, weighs 880 to 1,400 lbs (363 to 635 kg) less than a full-size truck. Chevrolet expects EPA fuel economy estimates for Colorado this summer.
This weight saving is a result of the slightly smaller overall dimensions of the Colorado, along with extensive use of lightweight materials, including high-strength steels and aluminum.
President Obama announces two new public-private manufacturing innovation institutes; new manufacturing innovation institute competition
February 25, 2014
President Obama announced two new manufacturing innovation institutes led by the Department of Defense supported by a $140-million Federal commitment combined with more than $140 million in non-federal resources: (1) a Detroit-area-headquartered consortium of businesses and universities, with a focus on lightweight and modern metals manufacturing; and (2) a Chicago-headquartered consortium of businesses and universities that will concentrate on digital manufacturing and design technologies.
Obama also launched a competition for a new manufacturing innovation institute to build US strength in manufacturing advanced composites, the first of four new competitions to be launched this year.
DOE to award up to $12M for technologies to produce renewable carbon fiber from biomass
February 04, 2014
The US Department of Energy (DOE) will award (DE-FOA-0000996) up to $12 million in funding to advance the development of a cost-competitive pathway to produce high-performance carbon fiber for vehicle lightweighting from renewable non-food biomass. Reducing a vehicle’s weight by just 10% can improve fuel economy by 6% to 8%.
Carbon fiber composites are lightweight, yet strong, materials that can greatly improve vehicle fuel efficiency when incorporated into structural and non-structural components. Carbon fibers are polymers that are typically made from petroleum and natural gas feedstocks (propylene and ammonia, respectively) that react to form acrylonitrile (ACN) which is then polymerized and spun into polyacrylonitrile (PAN).
New ceramic hollow fiber substrate for catalytic converters cuts fuel consumption, size and manufacturing costs
January 28, 2014
A new ceramic hollow fiber substrate for catalytic converters designed by Dr. Benjamin Kingsbury and colleagues at Imperial College London could cut the size and precious metal loading of the devices in automobiles while reducing fuel consumption and and manufacturing costs. Kingsbury has founded MicroTech Ceramics Ltd. as a spin-out to commercialize the technology.
The new structure can achieve a 2-3% fuel saving in engines (through the elimination of backpressure), or offer high performance cars an equivalent increase in engine power. It also enables the size of catalytic convertors to be reduced by around 50%, offering engine and exhaust system designers greater freedom. The new substrate can use up to 80% less rare metal, a development that could significantly reduce costs for vehicle manufacturers.
Constellium and UACJ plan JV in US to produce Body-in-White aluminium sheet for the automotive industry
January 24, 2014
Constellium N.V, a global aluminum products company formerly known as Alcan Engineered Products and headquartered in Amsterdam, and UACJ Corporation (UACJ), a Japan-based global aluminum manufacturer, are joining forces with a view to supply and market aluminum Body-in-White sheet to the North American automotive industry. To achieve this goal, Constellium and UACJ, through Tri-Arrows Aluminum Inc. (TAA), (UACJ’s subsidiary with Sumitomo Corporation and Itochu Group), intend to create a joint venture company in the United States, as an equal partnership, to serve the North American market.
The JV is expected to include a continuous heat treatment and conversion line with an initial target capacity of 100,000 metric tons supplied by cold rolled coils from both partners’ rolling mills. The planned facility is designed to allow for expansion beyond 100,000 tons. The total joint investment by both parties is expected to amount to approximately $150 million.
