The carbothermal reduction of silica into silicon requires the use of temperatures well above the silicon melting point (> or =2,000 degrees C). Solid silicon has recently been generated directly from silica at much lower temperatures (< or =850 degrees C) via electrochemical reduction in molten salts. However, the silicon products of such electrochemical… (More)
A sol-gel process was used, for the first time, to apply a multi-component, nanocrystalline, functional ceramic compound (BaTiO3) to a three-dimensional, self-replicating scaffold derived from a single-celled micro-organism (a diatom).
Barry, D. A Moon base offers more than just a good view, Chen, N-J. C5L2 is critical for the biological activities of the ana
