Technology
JCESR’s focus has changed to building transformational materials from the bottom up, atom-by-atom and molecule-by-molecule, where each atom or molecule plays a prescribed role in producing the desired overall materials performance. We could not have done this 10 years ago when the advanced scientific tools … Read More

Stability and Microheterogeneity in Concentrated Nonaqueous Electrolyte Solutions
We compared the molecular dynamics of two different but structurally-related electrolytes in highly concentrated solutions. One catholyte is compact and symmetrical; the other is bulkier and less symmetrical. Incoherent elastic and quasi-elastic neutron scattering measurements showed significant differences in crystallization, supercooling, and sudden microheterogeneity. Read More
