Aadith Moorthy Receives 2017 Henry Ford II Scholar Award

05-30-17

Materials science and computer science student Aadith Moorthy mentored by Professor Brent Fultz is a recipient of the 2017 Henry Ford II Scholar Award. He is working on improving graphene’s ability to store hydrogen, for use in fuel cell cars of the future. Moorthy is also the founder of ConserWater Technologies (conserwater.com), an Artificial Intelligence company that helps farmers reduce water use by up to 30%. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

Raising Temperature Changes an Element's Electronic "Topology"

10-27-16

Brent Fultz, Barbara and Stanley R. Rawn, Jr., Professor of Materials Science and Applied Physics, and colleagues have discovered a new way that heat tweaks the physical properties of a material. The potential value to engineers lies in the fact that it is much easier to raise the temperature of a material than it is to place it under the sort of pressure needed to force an electronic topological transition.

How Iron Feels the Heat

02-13-15

Brent Fultz, Barbara and Stanley R. Rawn, Jr., Professor of Materials Science and Applied Physics, and colleagues’ recent work provides evidence for how iron's magnetism plays a role in its curious properties—an understanding that could help researchers develop better and stronger steel. With a better computational model for the thermodynamics of iron at different temperatures—one that takes into account the effects of both magnetism and atomic vibrations—metallurgists will now be able to more accurately predict the thermodynamic properties of iron alloys as they alter their recipes.

An Incredible Shrinking Material

11-07-11

Graduate student, Chen Li, and colleagues including Brent Fultz,  Professor of Materials Science and Applied Physics, have shown how scandium trifluoride (ScF3) contracts with heat.  "A pure quartic oscillator is a lot of fun," Professor Fultz says. "Now that we've found a case that's very pure, I think we know where to look for it in many other materials." Understanding quartic oscillator behavior will help engineers design materials with unusual thermal properties. "In my opinion," Fultz says, "that will be the biggest long-term impact of this work."

Brent Fultz Receives 2010 TMS-EMPMD Distinguished Scientist Award

10-23-09

Brent Fultz, Professor of Materials Science and Applied Physics, is the recipient of the 2010 TMS-EMPMD Distinguished Scientist Award of The Minerals, Metals and Materials Society (TMS). The award includes a TMS conference symposium in honor of Professor Fultz that will emphasize the vibrational entropy of materials, and studies of vibrational entropy by inelastic neutron scattering and modern computational methods of materials science. This work was the basis for the award.

Michael Winterrose and Brent Fultz Use High-Pressure "Alchemy" to Create Nonexpanding Metals

07-01-09

Graduate student Michael Winterrose, and Brent Fultz, professor of materials science and applied physics, and colleagues, describe the exotic behavior of materials existing at high pressures in a paper in the June 12th issue of Physical Review Letters. By squeezing a typical metal alloy at pressures hundreds of thousands of times greater than normal atmospheric pressure, the material does not expand when heated, as does nearly every normal metal, and acts like a metal with an entirely different chemical composition. This insight into the behavior of materials existing at high pressures becomes doubly interesting when you consider that some 90 percent of the matter in our solar system exists at these high pressures.
