We apply non-vacuum processing to deposit dielectric capping layers on top of ultrathin atomic-layer-deposited aluminum oxide (AlOx) films, used for the rear surface passivation of high-efficiency crystalline silicon solar cells. We examine various s

Rat bone marrow stromal cell differentiation on aluminosilicate 3Al 2 O 3 –2SiO 2 coatings was investigated. Thin ceramic coatings were prepared on α-alumina substrates by the sol–gel process and calcined in order to establish an amorphous alumi

An amorphous nanoparticulate aluminosilicate 3/2-mullite precursor has been synthesized and carefully characterized. The sol contained 2-nm particles of Q3(3Al) silica species together with six-coordinated alumina, which suggested an allophane-like s
