Materials science matchmaker
September 25, 2014 — Scientific research may be the primary focus of the Department of Energy’s national laboratories, but for David Mandrus, the institutions play an equally important role in shaping the instruction and career paths of students.
September 16, 2014 — When Orlando Rios first started analyzing samples of carbon fibers made from a woody plant polymer known as lignin, he noticed something unusual. The material’s microstructure -- a mixture of perfectly spherical nanoscale crystallites distributed within a fibrous matrix -- looked almost too good to be true.
A Metallic Alloy That is Tough and Ductile at Cryogenic Temperatures
September 09, 2014 — A new concept in metallic alloy design – called “high‐entropy alloys” - has yielded a multiple-element material that not only tests out as one of the toughest on record, but, unlike most materials, the toughness as well as the strength and ductility of this alloy actually improves at cryogenic temperatures.
