Luminescent Lead Halide Perovskite Nanocrystals Embedded in Mesoporous Silica
By soaking mesoporous silica with perovskite precursor solutions followed by drying, lead halide perovskite nanocrystals are formed inside the silica pores. This material shows very bright photoluminescence (inset).

In-Situ Heating of Carbon-Coated LiFePO4
The thermal behavior of core-shell carbon-coated LiFePO4 nanoparticles, a promising battery material made by flame spray pyrolysis, during annealing was investigated by in-situ TEM. At a temperature of T = 700 °C, LiFePO4 starts to diffuse through the carbon shell resulting in cavities inside the mostly intact carbon shell. By increasing the temperature to T = 800 °C, the initial core-shell morphology is converted into open carbon shells and bulky LiFePO4 particles.
