Professor Lashmore's PhD early research at the University of Virginia, focused on the CVD synthesis and properties of polycrystalline steel fibers and their unique properties governed by the stress interactions between a ductile iron nanocore with a brittle, iron carbide matrix. Following his PhD he joined the Materials Science Division where he was instrumental in the development of artificial superlattices using electrochemical techniques. He conducted fundamental work in compositionally modulated alloys, which led to the developed of several successful commercial companies among these is Modumetal. He was the first to show the existing of two distinct amorphous states at the same composition and he developed a coated power technology now being used in the power metallurgy industry for soft magnetic materials. He also was instrumental in using fast diffusion processes to create difficult-to form intermetallic alloys at very low temperatures.
He left NIST in 1993 to co-found a company, Materials Innovation, focused on the development and production of coated metallic powders used for very high strength PM steels and soft magnetic alloys. He invented: (1) A highly coated uniform steel alloy formed from iron-nickel alloy powder, (2) A new kind of coated soft magnetic iron power that is now used for low core loss, high-energy efficiency electric motors, very fast response solenoids, and fuel injectors for Diesel engines. This material won the Powder Metallurgical Society’s award for invention of the year. He also co-invented a powder compaction press and powder feed system that won TIME Magazine’s award for invention of the year.
In 2002, he left Materials Innovations and joined Synergy Innovations from which Nanocomp was quickly spun out and is now a company of about 75 employees focused on the synthesis of carbon nanotube tapes and fibers. He developed all the patented technology used by Nanocomp.
He is now a Research Professor Materials Science and Physics at the University of New Hampshire where his efforts are focused on Boron Nitride Nanotubes high performance fiber, high performance batteries and on h-BN multijunction solar cells. Boron nitride nanotubes are a revolutionary material with unique multifunctional properties and great commercial potential. BNNTs have a structure similar to their well-known carbon nanotube (CNT) counterparts, but with alternating boron and nitrogen atoms self-assembling into a nanoscale tube whose diameter may range from 1 to 20nm and whose length may vary from 50 to 1000 microns. Due to their similar structure, BNNTs have the same phenomenal mechanical properties associated with CNTs, particularly their excellent mechanical strength and ability to be integrated into almost any shape. However, BNNTs offer additional, superior properties and characteristics when compared with CNTs, including very high temperature resistance.
Patents, Publications, Awards and Teaching: Altogether he holds 42 issued Patents and over 90 archival papers. Awards include; (1) the Wall Street Journal award, (2) NASA Nano-50, (3) Recognition by the White House of Nanocomp as a National Asset, (4) Time Invention of the Year for compact P/M press (2000) (5) Power Metallurgy Award for Advanced Soft Magnetic Materials (2000), (6) American Electroplaters and Surface Finishers International Research Award, (1994), (7) The Electrochemical Society Blum Award, (1992), (8) The Electrochemical Society Electrodeposition Research Award (1989). Total citations exceed 1811.
