Neutron diffraction and TSDC on Ba1−xUxF2+2x solid electrolytes

Resistance-change devices based on solid electrolytes

Scalable elements that can be switched between widely-separated non-volatile resistance states at very low power are desirable for applications in next generation memory and logic. One potential approach involves the use of solid electrolyte films. A mobile metal ion-containing electrolyte film sandwiched between an oxidizable metal layer and an inert electrode constitutes a device which revers...

Solid lithium electrolytes based on an organic molecular porous solid.

A new type of solid lithium-ion conducting electrolytes prepared by incorporation of Li(+) ions into a cucurbit[6]uril (CB[6])-based organic molecular porous solid shows high Li(+) ion conductivity (∼10(-4) S cm(-1)) and mobility (transference numbers, tLi(+) = 0.7-0.8). In addition, the solid electrolytes show excellent, thermally stable performance even after several temperature cycles.

Neutron diffraction analysis on FINEMET alloys

Neutron diffraction has been used to study in situ the nanocrystallization process of Fe73.5Cu1Nb3Si22.52xBx (x55, 9, and 12! amorphous alloys. Nanocrystallization results in a decrease of both the silicon content and the grain size of the Fe~Si! phase with increasing value of x. By comparing the radial distribution function peak areas with those predicted for ideal bcc and DO3 structure, it ca...

Neutron Diffraction Experiments

This ISEN award supported research toward improving the energy efficiency of actuators. The focused research objective was to develop next-generation shape memory alloy (SMA) models and structures, to demonstrate this new technology in targeted near-term applications on airplanes. Two research avenues were pursued to enable development of this new technology: 1) neutron diffraction experiments ...
