We report a treatment that enhances and stabilizes the photoluminescence (PL) from porous Si films. Films prepared by anodization in a 50% HF/ethanol solution were annealed at 450 °C in vacuum, exposed to air, and then exposed to a remote‐hydrogen

A porous silicon (PS) layer can be produced on a crystalline silicon substrate by electrochemical or chemical etching in hydrofluoric acid (HF) solutions. There are many properties that make PS thin films interesting for photovoltaic applications, su

To test the common assumption of no genetic relationship in a founding population, we calculated average relatedness (r) for the emigrants to Plymouth Colony from Europe on seven voyages from 1620 to 1633. Of 355 individuals, 255 could be individuall

The formation of mullite via gels prepared from technical ethyl silicate and aluminium chlorides has been studied. Normally, gels prepared specifically with the oxide stoichiometry of mullite (3Al2O3·2SiO2) do not form the mineral mullite on firing
