Daimler/Secar CRP hybrid struts receive AVK Innovation AWARD; intelligent material mix allows large-scale production
December 01, 2016
As part of a development project, researchers at Daimler AG and the Austrian CRP (carbon fiber reinforced plastics) applications specialist Secar Technologie GmbH have developed an innovative new CRP composite pultrusion process enabling carbon fibers and metal to be pultruded in profile form in larger volumes.
Pultrusion is a continuous molding process in which reinforcing fibers are saturated with a liquid polymer resin and then carefully formed and pulled through a heated die to form a part. Pultrusion results in straight constant cross section parts of virtually any shippable length.
Stanford team uses battery electrode materials to boost platinum catalytic performance for fuel cells
November 25, 2016
A team at Stanford University has developed a method for using battery electrode materials directly and continuously to control the lattice strain of a platinum (Pt) catalyst, thereby boosting catalytic activity for the oxygen reduction reaction (ORR) in fuel cells by up to nearly 90%. A paper on their work is published in Science.
Modifying the electronic structure of catalysts can improve their performance; lattice strain (either compressive or tensile) modifies the distances between surface atoms and hence modifies catalytic activity. However, the common approach of using metal overlayers to induce strain has some control issues, such as introducing ligand effects.
Saint Jean Carbon building a high performance lithium-ion battery with recycled/upcycled material
Saint Jean Carbon Inc., a carbon science company engaged in the design and build of energy storage carbon materials, and a battery manufacturing partner will build a high-powered full-scale lithium-ion battery with recycled/upcycled material from an electric car power pack and upcycled anode material from Saint Jean Carbon.
Saint John said that this project—a first—is intended to provide results showing that the battery materials can be re-used over and over again, greatly reducing the demand for continued mining and helping the environment significantly. The project will take a three-stage approach:
Ultrafine jagged Pt nanowires extremely efficient ORR catalysts; 50x more power than current commercial catalyst
November 18, 2016
An international team led by researchers at UCLA and Caltech has demonstrated that altering the form of platinum nanoscale wires from a smooth surface to a jagged one can significantly reduce the amount of precious metal required as a catalyst for the oxygen reduction reaction (ORR) in fuel cells and thus lower the cost. According to the findings, the newly developed catalyst is so active that the amount of platinum required for a fuel cell could be 1/50 of what is needed today.
In a paper published in Science, the team reports that the jagged Pt nanowires exhibit an ECSA (electrochemical active surface area) of 118 m2 per gram Pt and a specific activity of 11.5 mA per square centimeter for ORR for a mass activity of 13.6 ampere per milligram Pt, nearly doubling previously reported best values. Reactive molecular dynamics simulations suggested that the highly stressed, under-coordinated rhombohedral-rich surface configurations of the jagged nanowire enhanced ORR activity versus more relaxed surfaces.

Brown team creates patterned metal-oxide films using GO template; 4x charge-carrying capacity in Mn2O3
November 10, 2016
Researchers from Brown University have developed a new method for making ultrathin metal-oxide sheets containing intricate wrinkle and crumple patterns by transferring those patters from graphene oxide templates. In a study published in the journal ACS Nano, the researchers show that the resulting textured metal-oxide films have better performance when used as photocatalysts and as battery electrodes.
The new findings build on previous work done by the same research group in which they developed a method for introducing finely tuned wrinkle and crumple textures into sheets of the nanomaterial graphene oxide (GO). The study showed that the process enhanced some of graphene’s properties. The textures made the graphene better able to repel water, which would be useful in making water-resistant coatings, and enhanced graphene’s ability to conduct electricity.
ORNL-led team developing breakthrough high-temperature, high-strength Al alloy for advanced light-duty engines
November 08, 2016
A team led by researchers from Oak Ridge National Laboratory (ORNL) is developing a lower-cost cast aluminum (Al) alloy capable of at least a 50 ˚C temperature increase over the current cylinder head alloys 319 and 356 for use in light duty engines. The new alloy is also targeting a better than 25% increase in strength at 300 ˚C compared to the older alloys at 250 ˚C, as well as excellent hot tearing resistance.
The work, led by Dr. Amit Shyam at ORNL, is part of a 4-year project consisting of a CRADA partnership with FCA and foundry giant Nemak. (Earlier post.)
Roskill forecasts demand for neodymium for magnets to result in supply deficit; substitutions by 2021
In its new rare earths market report with forecasts out to 2026, Roskill, a leader in international metals and minerals research, observes that the permanent magnet and catalyst sectors will continue to provide the largest markets for rare earths in the next ten years to 2026. Catalysts will continue to drive growth in the light rare earth elements lanthanum and cerium, while permanent magnets will lead growth in neodymium, praseodymium and dysprosium.
However, Roskill also projects that, driven by rapidly increasing demand for neodymium-iron-boron (NdFeB) magnets (used in traction motors among other applications), neodymium will fall into deficit in 2016, although demand will initially be met by the drawdown of stocks. Roskill forecasts that the deficit will increase to 2021, making continued growth of NdFeB magnets unsustainable, despite efforts by rare earth producers to increase neodymium supply.
ORNL team shows 3D-printed permanent magnets outperform conventional versions, conserve rare materials
November 02, 2016
Researchers at the Department of Energy’s Oak Ridge National Laboratory (ORNL) and colleagues have demonstrated that permanent magnets produced by additive manufacturing can outperform bonded magnets made using traditional techniques while conserving critical materials. NdFeB magnets are used in a range of applications from computer hard drives and headphones to clean energy technologies such as electric vehicles and wind turbines.
The team fabricated isotropic, near-net-shape, neodymium-iron-boron (NdFeB) bonded magnets at DOE’s Manufacturing Demonstration Facility at ORNL using the Big Area Additive Manufacturing (BAAM) machine. The result, published in an open-access paper in Scientific Reports, was a product with comparable or better magnetic, mechanical, and microstructural properties than bonded magnets made using traditional injection molding with the same composition.

CarboSax: new joint venture for more sustainable carbon fiber production forms in Germany
October 13, 2016
PD Glasseiden, a Germany-based producer of fiberglass; European Carbon Fiber GmbH; and the ForschungsCampus Open Hybrid LabFactory e.V., established under the auspices of the Lower Saxony Research Centre for Vehicle Technology at the TU Braunschweig and Volkswagen AG have formed a joint venture—CarboSax GmbH—to pursue developing, manufacturing and distributing more sustainable carbon fibers in Germany.
In the first step at a location in Chemnitz, Saxony, CarboSax will build a pilot line for the sustainable production of carbon fibers. The objective of this carbon fiber pilot line production is a significant reduction in production costs by 30% over currently available commercial carbon fibers. This cost reduction is required to further enable the use of carbon fiber in mass production in the automotive industry, mechanical engineering and wind power. An equal objective is a reduction of at least 50% in CO2 emissions from carbon fiber production.

At its recent annual meeting in Albany, Calif., the public-private consortium behind the Biomass Research and Development Initiative (BRDI) grant, “Securing the Future of Natural Rubber—an American Tire and Bioenergy Platform from Guayule,” reported several key advancements emerging from the group’s work over the past year.
Cooper Tire & Rubber Company, working as the lead agency in the grant, announced that its scientists have reached a key milestone toward the goal of producing, by mid-2017, a concept tire in which all of the natural and synthetic rubber is replaced by guayule-based polymers. Guayule is a shrub that is grown primarily in the southwestern United States and contains rubber that can be processed for use in tires. (Earlier post.)
Liverpool team develops better material for PEM fuel cells; porous organic cage solids with 3D protonic conductivity
September 14, 2016
Proton conduction is key to devices such as proton exchange membrane fuel cells (PEMFCs); the performance-limiting component in PEMFCs is often the proton exchange membrane (PEM). In the search for more effective PEMs, reseachers have looked to porous solids such as metal-organic frameworks (MOFs) or covalent organic frameworks. With these, the proton conduction properties can be fine-tuned by controlling crystallinity, porosity and chemical functionality. To maximize proton conduction, three-dimensional conduction pathways are preferred over one-dimensional pathways, which prevent conduction in two dimensions.
Researchers led by a team at the University of Liverpool (UK) now report in an open-access paper in the journal Nature Communications that they have developed crystalline porous molecular solids where the proton transport occurs in 3D pathway by virtue of the native channel structure and topology. The development could lead to the design of more effective fuel cell materials, including high-temperature PEMFCs.
Kiel nanoscale-sculpturing makes metal surfaces strong, resistant, and multifunctional; multi-material joining
September 08, 2016
Researchers at the University of Kiel (Germany) have developed a new process—which they call “nanoscale-sculpturing”—for the surface preparation of metals.
Nanoscale-sculpturing, which is based on knowledge from semiconductor etching, turns surfaces of everyday metals into their most stable configuration, but leaves the bulk properties unaffected. Thus, nanoscale-sculpturing ensures stronger, reliable joints to nearly all materials, reduces corrosion vastly, and generates a multitude of multifunctional surface properties. An open-access paper on their work is published in the RSC journal Nanoscale Horizons.
SLAC, Utrecht Univ. team visualize poisoning of FCC catalysts used in gasoline production; seeing changes in pore network materials
August 31, 2016
Merging two powerful 3-D X-ray techniques, a team of researchers from the Department of Energy’s SLAC National Accelerator Laboratory and Utrecht University in the Netherlands revealed new details of the metal poisoning process that clogs the pores of fluid catalytic cracking (FCC) catalyst particles used in gasoline production, causing them to lose effectiveness.
The team combined their data to produce a video that shows the chemistry of this aging process and takes the viewer on a virtual flight through the pores of a catalyst particle. More broadly, the approach is generally applicable and provides an unprecedented view of dynamic changes in a material’s pore space—an essential factor in the rational design of functional porous materials including those use for batteries and fuel cells. The results were published in an open access paper in Nature Communications.

Invented by LeMond CEO Connie Jackson and a research team at ORNL’s Carbon Fiber Technology Facility (CFTF), the process is projected to reduce production costs by more than 50% relative to the lowest-cost industrial-grade carbon fiber.
Opinion: Could A Lithium Shortage De-Rail The Electric Car Boom?
August 26, 2016
by James Stafford of Oilprice.com
We’ve gone electric, and there’s no going back at this point. Lithium is our new fuel, but like fossil fuels, the reserves we’re currently tapping into are finite—and that’s what investors can take to the bank.
You may think lithium got too popular too fast. You may suspect electric vehicles are too much buzz and not enough real future. You may, in short, be a lithium skeptic, one of many. And yet, despite this skepticism, lithium demand is rising steadily and sharply, and indications that a shortage may be looming are very real.

New approach for synthetic rubber for degradable tires: converting cyclopentene to polypentenamers
A team from the Texas A&M University campus in Qatar (TAMU-Qatar) and Caltech has developed a new way to make synthetic rubber; once this material is discarded, it can be easily degraded back to its chemical building blocks and reused in new tires and other products. The researchers will present their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS) in Philadelphia.
According to the Rubber Manufacturers Association, nearly 270 million tires were discarded in the US in 2013—more than one tire per adult living in the country. Many of the non-degradable scrap tires get stockpiled in landfills. More than half go on to become tire-derived fuel—shredded scrap tires that get mixed with coal and other materials to help power cement kilns, pulp and paper mills and other plants. But environmentalists are concerned that the emissions from this practice could be adding harmful pollutants to the air.
IACMI, DuPont and Purdue partner on automotive carbon-fiber composites
August 18, 2016
The Institute for Advanced Composites Manufacturing Innovation, IACMI, in partnership with DuPont Performance Materials, Fibrtec Inc. and Purdue University, has launched the first project selected with a dual focus on decreasing the cost of manufacture and increasing design flexibility for automotive composites. Advancements in both areas can open up new opportunities and become an enabler for large-scale deployment of composite parts.
Multiple factors, including cost and design constraints, present barriers to the adoption of composites in high volume automotive applications. This new IACMI project will address both of these critical areas through a fundamentally different approach to the manufacturing of carbon fiber composites versus those currently in use today.

Researchers gain better insight into transformation of steel; managing nucleation could limit need for alloying elements
August 10, 2016
Researchers at TU Delft have shed new light on the process of nucleation in the polymorphic transformation of solid materials—specifically, steel. Polymorphism is the ability of a solid material to exist in more than one phase or crystal structure. Polymorphism may occur in metals, alloys, ceramics, minerals, polymers, and pharmaceutical substances.
In an open access paper published in Nature’s Scientific Reports, the team presented in-situ three-dimensional x-ray diffraction (3DXRD) microscopy measurements of the ferrite (α) to austenite (γ) transformation in steel during heating, which the team performed at the European Synchrotron Radiation Facility.
CNT nanostiches strengthen laminated composites
August 03, 2016
A team from MIT and Saab AB has found a way to bond composite layers in such a way that the resulting material is substantially stronger and more resistant to damage than other advanced composites. Their results are published this week in the journal Composites Science and Technology.
The team reinforced aerospace-grade unidirectional carbon fiber laminate interfaces with high densities (>10 billion fibers per cm2) of aligned carbon nanotubes (A-CNTs) that act as nano-scale “stitches”. Such nano-scale fiber reinforcement of the ply interfaces has already been shown to increase interlaminar fracture toughness; the MIT researchers showed that laminate in-plane strengths are also increased via the technique.

The Steel Market Development Institute (SMDI)—a business unit of the American Iron and Steel Institute (AISI)—has now released its 2016 Steel Industry Technology Roadmap for Automotive.
The roadmap outlines the long-term technology needs to support future automotive material selection decisions with advanced high-strength steel (AHSS) including, optimized design, fuel economy, strength and durability, environmental performance and value.
EIA projects energy intensity of US steel production to drop 27% by 2040
July 29, 2016
Steel production is energy-intensive; in 2015, the steel industry accounted for 1.5% of all industrial shipments in the US but 6.1% of industrial delivered energy consumption. The US Energy Information Administration’s (EIA) Annual Energy Outlook 2016 (AEO2016) Reference case projects that energy use in the steel industry will further increase by 11% over 2015–2040.
Over the same period, however, the AEO2016 projects in its Reference case a 27% drop in the steel industry’s energy intensity, compared with an 18% reduction in total industrial energy intensity. Several alternative cases examine drivers for further energy intensity reductions in the steel industry.
Study: Overall automotive aluminum recycling rate above 90%
New research from the Worcester Polytechnic Institute’s (WPI) Center for Resource Recovery and Recycling calculated an overall recycling rate of 91% for automotive aluminum. The peer-reviewed study, funded by the Aluminum Association, examines how much aluminum used in the United States’ light-duty automotive sector is recovered and recycled from vehicles at end of life.
The new study, Automotive Aluminum Recycling at End of Life: A Grave-to-Gate Analysis, details a “grave-to-gate” analysis, which spans the moment an automobile becomes obsolete to the moment the aluminum metal units are completely recycled and enter back into life as input material for new applications, including vehicles. Researchers attribute automotive aluminum’s high recycling rate to the metal’s economic value, citing the “concerted effort to recover this valuable lightweight commodity from end-of-life vehicles.”
Utah, Minnesota team discover highly conductive oxide-based materials; STO/NTO offer “different road to power electronics”
July 27, 2016
Engineers from the University of Utah and the University of Minnesota have discovered that interfacing two particular oxide-based materials—strontium titanate (STO) and neodymium titanate (NTO)—makes them highly conductive, a boon for future power electronics that could result in more power-efficient laptops, electric cars and home appliances that also don’t need cumbersome power supplies. Their findings were published in an open access paper in the journal, APL Materials, from the American Institute of Physics.
The team led by University of Utah electrical and computer engineering assistant professor Berardi Sensale-Rodriguez and University of Minnesota chemical engineering and materials science assistant professor Bharat Jalan revealed that when the two oxide compounds interact with each other, the bonds between the atoms are arranged in a way that produces many free electrons—the particles that can carry electrical current. STO and NTO are by themselves known as insulators—i.e., not conductive at all. When they interface, however, the amount of electrons produced is a hundred times larger than what is possible in semiconductors.
LLNL researchers build scalable ultra-lightweight and flexible 3D-printed metallic materials
July 21, 2016

July 20, 2016
Ford Motor Company is teaming up with Jose Cuervo to explore the use of the tequila producer’s blue agave plant fiber byproduct to develop more sustainable bioplastics to employ in Ford vehicles.
Ford and Jose Cuervo are testing the agave-fiber-reinforced bioplastic for use in vehicle interior and exterior components such as wiring harnesses, HVAC units and storage bins. Initial assessments suggest the material holds great promise due to its durability and aesthetic qualities. Success in developing a sustainable composite could reduce vehicle weight and lower energy consumption, while paring the use of petrochemicals and the impact of vehicle production on the environment.
Ultra high-strength materials reduce heavy-duty cylinder liner distortion; GOE330 compacted graphite iron
Federal-Mogul Powertrain has become the first company to bring ultra high-strength iron cylinder liners into series production. Made of a special form of compacted graphite iron (CGI), the latest formulation—designated GOE330—reduces the typical bore distortion under maximum piston side thrust by up to 27%, compared to existing iron materials. It is used in liner applications between 100 mm and 190 mm bore.
The Young’s Modulus of GOE330 is more than 15% greater than existing high-strength iron liner materials, while at 270 MPa its fatigue strength is approximately one-third higher. Future developments are planned that will achieve even higher levels of strength and stiffness.

Neos and Lockheed Martin to develop enhanced next-gen airborne gravity gradiometer to advance ability to find oil, gas & minerals
July 06, 2016
In partnership with Lockheed Martin, Neos Inc. will develop a new generation sensor to be used to find oil, gas and minerals beneath the earth’s surface from the air. The new Full Tensor Gradiometry (FTG) Plus technology has 20 times the sensitivity and 10 times greater bandwidth than current gravity gradiometers, according to Neos.
Gravity gradiometers have been commercially used for more than 20 years and militarily longer than that. The technology is based on the principle that earth’s gravity field varies with location, local topography and sub-surface geologic features. Measuring the gravity variation caused by items beneath the earth’s surface can help identify unique underground and undersea geologic structures. The new airborne FTG Plus sensor is so advanced it could find a 10-meter tall hill buried one kilometer below the earth’s surface.

Materials Project releases trove of data to public; support for work on multivalent battery chemistries and electrolytes
June 10, 2016
The Materials Project, a Google-like database of material properties aimed at accelerating innovation (earlier post), has released an enormous trove of data to the public, giving scientists working on batteries, fuel cells, photovoltaics, thermoelectrics, and other advanced materials a powerful tool to explore new avenues of research.
Two sets of data were released: nearly 1,500 compounds investigated for multivalent intercalation electrodes and more than 21,000 organic molecules relevant for liquid electrolytes as well as a host of other research applications. Batteries with multivalent cathodes (which have multiple electrons per mobile ion available for charge transfer) are promising candidates for reducing cost and achieving higher energy density than that available with current lithium-ion technology. (Earlier post.)
New TM4 SUMO medium-duty electric motors boost torque and speed 45% with SMCs in place of permanent magnets
June 08, 2016
TM4 will introduce three new SUMO medium-duty (MD) powertrain options at the 29th Electric Vehicle Symposium & Exhibition (EVS29), offering an increase of up to 45% in torque and speed, thanks to a new technological advancement.
Until now, the main rotor technology found in TM4’s electric motors was based on surface-mounted permanent magnets. The desire to limit the use of rare-earth magnets has resulted in a technology choice that leverages the reluctance torque of TM4’s external rotor design (earlier post) and decreases by 25% the use of these elements. By substituting some of the magnets with soft magnetic composites (SMCs), variable reluctance adds up to 45% extra torque and operating speed compared with previous technology in same package dimensions.

The resulting materials showed strong magnetic properties and energy-storing capabilities. The approach could signal an efficient new strategy toward replacing rare earths in permanent magnets such as those uses in electric motors and keeping costs stable, the researchers said. A paper on their work is published in the ACS journal Chemistry of Materials.
ORNL team engineers 1st high-performance, two-way oxide catalyst; outperforms platinum; potential for new electrochemistry systems
May 28, 2016
A research team led by Oak Ridge National Laboratory (ORNL) has created the first high-performance, two-way oxide catalyst and filed a patent application for the invention. The new bi-directional catalyst can outperform platinum in oxygen reduction and oxygen evolution reactions (ORR and OER). The accomplishment is reported in the Journal of the American Chemical Society.
The discovery may guide the development of new material systems for electrochemistry. Energy storage devices, such as fuel cells and rechargeable batteries, convert chemical energy into electricity through a chemical reaction. Catalysts accelerate this process, making it more efficient. In particular, an oxygen reduction catalyst extracts electrons from oxygen molecules, while an oxygen evolution catalyst drives the reaction in the opposite direction. Catalytic reactions that proceed in both directions are required for charging and discharging of regenerative energy storage devices.
Novelis commissions $120M finishing line for automotive aluminum sheet; importance of the closed-loop recycling program
May 26, 2016
Novelis, the world leader in aluminum rolling and recycling, celebrated the commissioning of its third CASH (Continuous Annealing Solution Heat) treatment finishing line for aluminum automotive sheet in Oswego, NY. Installed to support the production of stronger, lighter and safer vehicles, the $120-million CASH 3 line expands the company’s production to supply aluminum sheet for the body and cargo box of Ford’s 2017 F-150 SuperDuty pickups. The CASH 1 and 2 lines supply aluminum for Ford’s F-150. With the addition of the third CASH line in Oswego, Novelis has furthered its position as the leading automotive aluminum sheet supplier in North America.
The commissioning of the CASH 3 line also marks the expansion of the benchmark closed-loop recycling program—developed by Novelis, Ford and Penske—which processes roughly 25 million pounds of automotive aluminum scrap per month—more than enough to build 30,000 F-150 bodies. (Earlier post.) Recycled aluminum, which requires significantly less energy and water, avoids 95% of the greenhouse gas emissions associated with primary aluminum production.
DSD and Solvay partner on use of structural plastics for lighter and more efficient transmissions
Automotive engineering consultancy Drive System Design (DSD) and international chemical and advanced materials company, Solvay SA, have entered a development partnership to make the large scale use of structural plastic composites in transmissions a viable solution for future vehicles. DSD is contributing the transmission know-how while Solvay the materials expertise.
There is an immediate weight saving from substituting plastic materials for conventional metal castings but equally important is the potential for improved efficiency due to the greater inherent damping provided by polymeric materials, the partners said. This permits the use of gears that are much more efficient but would have unacceptable noise characteristics in a conventional casing.
ORNL team develops laser process for lower cost, more robust joining of carbon fiber and aluminum
May 20, 2016
Researchers led by a team from Oak Ridge National Laboratory (ORNL) have developed a new laser process that could make joining carbon fiber composites and aluminum for lightweight cars and other multi-material high-end products less expensive—as well as making the joints more robust.
The process would replace the practice of preparing the surface of the materials by hand using abrasive pads, grit blasting and environmentally harmful solvents. Using a laser to remove layers of material from surfaces prior to bonding improves the performance of the joints and provides a path toward automation for high-volume use.
Max Planck, MIT researchers develop new strategy for high-entropy alloys; overcoming the strength/ductility tradeoff
May 19, 2016
Researchers at the Max Planck Institute in Dusseldorf, Germany, and MIT have developed a novel strategy to design nanostructured, bulk high-entropy alloys (HEAs) (earlier post) with multiple compositionally equivalent high-entropy phases. The new approach is described in a paper this week in the journal Nature.
The result, says C. Cem Tasan, the Thomas B. King Career Development Professor of Metallurgy in MIT’s Department of Materials Science and Engineering, also challenges the conventional wisdom that improving the strength of a metal alloy is always a tradeoff that results in a loss of ductility.
Ford first automaker to use captured CO2 to develop foam and plastic for vehicles

It could be employed in seating and underhood applications, potentially reducing petroleum use by more than 600 million pounds annually. CO2-derived foam will further reduce the use of fossil fuels in Ford vehicles and increase the presence of sustainable foam in the automaker’s global lineup.
Stanford team develops nanofiber air filters for efficient high-temperature removal of PM2.5
A team at Stanford has developed high-efficiency (>99.5%) polyimide-nanofiber air filters for the removal of PM2.5 from exhaust streams. In a paper published in the ACS journal Nano Letters, the researchers report that the new polyimide nanofibers exhibit high thermal stability. The PM2.5 removal efficiency was kept unchanged when temperature ranged from 25–370 °C.
The filters feature high air flux with very low pressure drop. A field-test showed that the new nanofibers could effectively remove >99.5% PM particles from car exhaust at high temperature. Some versions of the filters removed PM2.5 with efficiency higher than 99.98%—the standard of HEPA filters defined as filters with filtration efficiency >99.97% for 0.3 μm airborne particles.
ORNL exclusively licenses plasma processing technology for carbon fiber production to RMX Technologies; 75% less energy, 20% lower cost
May 13, 2016
RMX Technologies and the Department of Energy’s Oak Ridge National Laboratory have signed an exclusive licensing agreement for a new technology that significantly reduces the time and energy needed in the production of carbon fiber. Combing these benefits with a low-cost precursor currently in development, the result can be a carbon fiber product that is 40% less expensive to manufacture than current commercial products.
The ORNL/RMX plasma processing technology is a new approach to the oxidation stage of carbon fiber production in which polymer materials are oxidized (or stabilized) before carbonization. During oxidation, the thermoplastic precursor is converted to a thermoset material that can no longer be melted. Oxidation is the most time-consuming phase of the multistep carbon fiber conversion process.

Cactus-inspired membranes with nanocrack coatings boost fuel cell performance significantly
April 29, 2016
Regulating water content in polymeric membranes is important in a number of applications—such as in the proton-exchange fuel-cell membranes used in automotive fuel cell stacks. Researchers from CSIRO in Australia and Hanyang University in Korea have now developed a new type of hydrocarbon polymer membrane that has the potential to deliver a significant boost in fuel cell performance.
Water content in the membranes is regulated through nanometer-scale cracks (nanocracks) in a hydrophobic surface coating. These cracks work as nanoscale valves to retard water desorption and to maintain ion conductivity in the membrane on dehumidification. In a paper published in the journal Nature, the researchers reported that hydrocarbon fuel-cell membranes with these surface nanocrack coatings operated at intermediate temperatures show improved electrochemical performance.

PNNL team develops higher-strength, lower-cost titanium alloy aimed at improving vehicle fuel economy and reducing CO2 emissions
April 02, 2016
An improved titanium alloy—stronger than any commercial titanium alloy currently on the market—gets its strength from the novel way atoms are arranged to form a special nanostructure. For the first time, a team led by researchers at Pacific Northwest National Laboratory (PNNL) have been able to see this alignment and then manipulate it to make the strongest titanium alloy (hierarchical nanostructured Ti-185, or HNS Ti-185) yet developed. On top of the gains in strength, the new alloy benefits from a lower cost process.
In an open access paper published in the journal Nature Communications, the researchers note that that material is an excellent candidate for producing lighter vehicle parts, and that this newfound understanding may lead to creation of other high strength alloys.
New Federal-Mogul Powertrain piston skirt coatings increase durability for the life of pistons
March 30, 2016
Federal-Mogul Powertrain has introduced two innovative piston skirt coatings: EcoTough-New Generation (for gasoline engines) and EcoTough-D (for diesel engines). Building on the proven performance of previous EcoTough coatings, the new formulations further reduce engine friction, wear and noise while dealing with the increasingly challenging loads and temperatures that exist in the latest downsized, turbocharged engines.
Gasoline and diesel engines require alternative solutions because of important differences in their relative combustion loads, piston geometry and the lubricity of their respective fuels. Federal-Mogul Powertrain has accommodated these differences by formulating specific coatings, each optimized for either gasoline or diesel application.

A detailed analysis of the new process compared to a published baseline for conventional carbon fiber production examined manufacturing cost of nine major process steps, starting with the precursor and pretreatment and finishing with surface treatment, sizing, winding, inspection and shipping. The analysis revealed the new process yields significant reductions in materials, capital and labor costs resulting in an overall manufacturing cost reduction of up to 50%. Details of the cost analysis will be shared with the prospective licensees.
ORNL team develops better moldable thermoplastic by using lignin; 50% renewable content
March 23, 2016
Researchers at Oak Ridge National Laboratory (ORNL) have developed a new class of high-performance thermoplastic elastomers for cars and other consumer products by replacing the styrene in ABS (acrylonitrile, butadiene and styrene) with lignin, a brittle, rigid polymer that, with cellulose, forms the woody cell walls of plants.
In doing so, they have invented a solvent-free production process that interconnects equal parts of nanoscale lignin dispersed in a synthetic rubber matrix to produce a meltable, moldable, ductile material that’s at least ten times tougher than ABS. The resulting thermoplastic—called ABL for acrylonitrile, butadiene, lignin—is recyclable, as it can be melted three times and still perform well. The results, published in the journal Advanced Functional Materials, may bring cleaner, cheaper raw materials to diverse manufacturers.

HRL Labs team develops 3D printing process for ceramics; propulsion components, microelectromechanical systems and more
January 01, 2016
Researchers at HRL Laboratories have achieved a new milestone in 3D printing technology by developing a process that overcomes the limits of traditional ceramic parts and enables the development of high temperature, high strength ceramic components. Because ceramics cannot be cast or machined easily, three-dimensional (3D) printing enables a big leap in geometrical flexibility. A paper on their work is published in the journal Science.
The extremely high melting point of many ceramics makes them challenging for additive manufacturing as compared with metals or polymers. The HRL team developed pre-ceramic monomers that are cured with ultraviolet light in a stereolithography 3D printer or through a patterned mask, forming 3D polymer structures that can have complex shape and cellular architecture.
UCLA researchers develop exceptionally strong and lightweight new metal nanocomposite
December 24, 2015
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal nanocomposite with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.
To create the super-strong but lightweight metal, the team developed a new way to disperse and stabilize nanoparticles in molten metals. They also developed a scalable manufacturing method that could pave the way for more high-performance lightweight metals. A paper on their work is published today in Nature.
