How Should Resources From National Stockpiles Be Managed?

The Strategic National Stockpile (SNS) is a national system maintained by the US federal government to deliver medical supplies during emergencies. In the past, the SNS has been used to mitigate public health consequences of tragedies, such as Hurricane Katrina and Ebola outbreaks. However, challenges in maintaining and utilizing the SNS for patient safety are prevalent.

Controlled Homoepitaxial Growth of Hybrid Perovskites.

Organic-inorganic hybrid perovskites have demonstrated tremendous potential for the next-generation electronic and optoelectronic devices due to their remarkable carrier dynamics. Current studies are focusing on polycrystals, since controlled growth of device compatible single crystals is extremely challenging. Here, the first chemical epitaxial growth of single crystal CH NH PbBr with controlled locations, morphologies, and orientations, using combined strategies of advanced microfabrication, homoepitaxy, and low temperature solution method is reported.
