On the origin and underappreciated effects of ion doping in silica
The origin of selectivity in the hollowing of silica nanoparticles is investigated to further understand silica. It is realized that, during the synthesis, the silica precursors are essentially ion-paired polyelectrolytes, ...
General formation of MS (M = Ni, Cu, Mn) box-in-box hollow structures with enhanced pseudocapacitive properties
Complex hollow structures of metal sulfides could be promising materials for energy storage devices such as supercapacitors and lithium-ion batteries. However, it is still a great challenge to fabricate well-defined metal ...
