Guo J., Guo X., Guo J., Guo X., Dong J., Wang S., Gong J., Zhu R., Ding W., Shanghai Jiao Tong University, CN

Abstract A single bath of ionic liquid electrodeposition method has been developed for the preparation of (Ni-Cu)/(Cu-Ni) multilayers on AZ91D magnesium alloy. The technique has been used to make multilayers with a composition of (92.47at.%Ni-7.53at.%Cu) [...]

Upconverting Nanophosphors for High Temperature Sensing Applications

Guo X., Zhao H., Song H., Chen Q., Li K.K., Zou Y.K., Jiang H., Combs C., Narayanaswamy V., Clemens N., Boston Applied Technologies, Inc., US

In this work, a unique upconverting thermographic phosphor technique was developed for overcoming the difficulties encountered currently in the down-conversion route. Upconverting nanopowders of rare earths doped refractory oxides were synthesized through a wet chemical [...]
