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

Solvation Structure and Dynamics of Mg(TFSI)2 Aqueous Electrolyte
Using MD simulations, SAXS, and PFG-NMR, the solvation structure and ion dynamics of Mg(TFSI)2 aqueous electrolytes were investigated. We found the rigid solvation structure around Mg ion increases the effective ion size, which further leads to comparable diffusivity of Mg and TFSI ion, in contrast … Read More
