A new way to detect radiation involving cheap ceramics could lead to plethora of new applications, including better detectors for nuclear materials at ports.

We report novel calcium-substituted perovskite-type solid state electrolyte with nominal composition Li0.344Sr0.433Ca0.02Ta3/4Hf1/4O3, which we compare with Li3/8Sr7/16Ta3/4Hf1/4O3. The compounds were synthesized via solid-state reaction and studied by X-ray and neutron powder diffraction and electrochemical impedance spectroscopy. Neutron powder diffraction allowed the Li position in the structure to be accurately determined. Calcium-substituted phase showed higher Li-ion conductivity than the ...

To develop advanced materials, a deep understanding of their underlying microstructure and chemistry is necessary. Knowing how defects influence the interplay between microstructure and chemical c ...

How to make energy conversion more efficient and use waste heat for electricity? Researchers of the Max-Planck-Institut für Eisenforschung tuned the microstructure of thermoelectric materials by d ...

MIT researchers are working toward new cybersteels developed with computing technology. Future applications of these advanced materials include printed aircraft components and ship hulls that are harder to detect.

Engineers have demonstrated for the first time how light can be used to significantly improve the performance of fuel cells, lithium batteries, and other devices that are based on the movement of charged atoms, or ions.
