“The rapid evolution of small unmanned air systems (sUAS) technologies is fueling the exponential growth of the commercial drone sector, creating new asymmetric threats for warfighters. sUASs’ size and low cost enable novel concepts of employment that present challenges to current defense systems. These emerging irregular systems and concepts of …

In the past few years, metal halide perovskite quantum dots and nanocrystals have been extensively explored due to their unique optoelectronic properties and extensive application prospects. Perovskites are materials that share a crystal structure similar to the mineral called perovskite, which consists of calcium titanium oxide (CaTiO3). Depending on which …
