NSF invests $12M in 14 materials-by-design research projects as part of Materials Genome Initiative

12 October 2012

The National Science Foundation (NSF), in support of the federal multi-agency Materials Genome Initiative (MGI) (earlier post), has now granted the first awards for the Designing Materials to Revolutionize and Engineer our Future (DMREF) program.

The NSF Mathematical and Physical Sciences (MPS) and Engineering (ENG) Directorates invested a total of just over $12 million for 22 grants in support of 14 distinct DMREF projects intended to yield a range of new developments, including new lightweight yet rigid polymers; highly durable, multi-layered materials for aircraft engines and power plants; new data storage technology based on spin electronics; new thermoelectric composites for converting heat to electricity; novel designer glasses; membranes that function as well as biological counterparts; new techniques to develop exceptionally hard coatings; and others.

DMREF Thermoelectrics
The DMREF project on high-efficiency thermoelectric composites is led by Jihui Yang at the University of Washington, and is slated to receive a $900,000 award from NSF.
The team is proposing a new hierarchical multiscale strategy that builds upon atomistic-nano-continuum computation guided material design; interfacial modification techniques; bulk functional gradient approaches; and nano-to-continuum characterization methodologies that are being developed at the Univ. of Washington and at the GM R&D Center.
“Connecting fundamental electronic structure studies of alloys and interfaces at the atomistic scale and bridging this to continuum modeling for new materials design; coupling with materials synthesis and characterization for validation; and direct incorporation in industrial usage is a potentially transformative concept in materials science and engineering. It offers the promise to move beyond the existing trial-and-error approaches.”
—Project abstract

DMREF grantees, in collaboration with industry partners, are targeting one of the primary MGI goals: to halve the current time and cost for transitioning breakthroughs from the laboratory to the marketplace—a process that can take as long as two decades.

DMREF involves the development of new physically-based and verified computational tools to accelerate the discovery, development and property optimization of new materials and systems. That requires an understanding of how to synthesize and process materials to achieve desired properties and performance. Coupling those new materials with advanced manufacturing tools will accelerate their introduction into products, and at a lower cost than through standard approaches.

The driving force behind MGI and DMREF is a materials innovation infrastructure in which a new understanding of physical and chemical processes, properties and materials performance drives the development and validation of next-generation algorithms and software. Experimental and computational approaches are key to DMREF, which along with the emerging field of materials informatics, work in a synergistic partnership, each challenging and pushing the other in new directions. Success for DMREF and MGI hinges on the success of that partnership.

—Ian Robertson, director of NSF’s Division of Materials Research

DMREF is guided by the concept of materials-by-design, an approach where researchers model unique, new materials that offer the particular structure and properties desired, and then craft the materials— for some technologies, beginning even below the nanometer (billionths of a meter) scale. Researchers refine the materials throughout the design process, but with greater understanding and control than many traditional approaches, yielding a faster delivery time to get the material to market.

Three of the projects are co-funded through NSF’s Grant Opportunities for Academic Liaison with Industry (GOALI) program, which links university researchers with industry partners, enabling joint university-industry research and allowing university researchers and students access to industry facilities.

A key element of the DMREF effort is to foster discoveries that lead to effective tools and methods for materials scientists and engineers to utilize in design and practice— as well as for further research endeavors. To do this effectively and rapidly, partnerships between NSF-sponsored investigators and students and their industry partners are essential to communicate both critical needs and emerging opportunities from DMREF research discoveries. The use of the GOALI program provides those opportunities for DMREF grantees

—Steven McKnight, director of NSF’s Division of Civil, Mechanical and Manufacturing Innovation

MGI, coordinated by an interagency subcommittee chaired by Cyrus Wadia, Assistant Director for Clean Energy and Materials R&D at the White House Office of Science and Technology Policy, consists of the National Science Foundation, the Department of Energy, Department of Defense, and National Institute of Standards and Technology. The total investment in MGI is expected to be $100 million.

Clean abundant energy is now being used in the most famous distant off-road vehicle. It does not use solar power because it is too dilute and expensive. Its power plant is so safe that smaller versions are operating in some human bodies.

This vehicle is the most far off road vehicle except for its smaller cousins that have failed or are failing. It is millions of miles away from any road, and in its heart a metal is giving off heat which keeps the electronics warm and also provides power to the wheels and test equipment. It is on Mars. The same metal was used in its cousins, but just to keep them warm at all times even in the dark. The atom of the metal has 94 protons and 144 neutrons. Half of these atoms will be gone in 80 years and the heat supplied to the vehicle will be only half and the power less than half which is very good since the vehicle did not have to get more fuel in all those years. There are only a few tens of pounds of this metal on the face of the earth, but it could be made in ton quantities for vehicles that would need no new fuel for the life of a human owner.

Take a pound of butter and cut it into 20 slices. This is the size of a pound of a similar metal which can be used to produce an amount of heat similar to the heat produced by the burning of three million pounds of coal and over six million pounds of oxygen. The coal combustion produces ten million pounds of waste, but the metal only one, but its minimum size might be as much as two slices of butter. ..HG..

HG....could you elaborate how the heat is converted to electricity and how large and durable is the converter?

Curiosity uses lead-telluride thermocouples to supply its electricity (powered by the heat of decaying Pu-238).

And I am fairly certain that it is on Harvey and Henry's home planet.
