Following the discovery of electricity and the division of labor in the 1870s, machine structure and precision dramatically improved from the macro-to the micro size, enabling interchangeability and mass production. In the second half of the 20th century, the synergy of optics and light-induced ...
Barium titanate thin films are grown by atomic layer deposition (ALD) at 340 掳C from barium cyclopentienyl and titanium methoxide precursors. H2O is used as the oxygen source. Binary reactions of Ba( t Bu3C5H2)2 and H2O are first studied separately in BaO deposition and are found to ...
been examined for concretes made from mixtures of Portland cement with finely divided calcium, strontium, and barium carbonates taken in various mass ratios; the main form in which carbon-14 is immobilized is as the compound obtained from calcium carbonate and cement with a mass ratio of 1:1....
Unlike the barium, the salt of strontium does not produce a mass spectrum dominated by the +2 charge state. Considerable adduct formation is noted from the single Vrf chronogram and also attributed to ion source conditions.Spiros Z. Manolakos...
Residual mass from TG can help to assess the volatilization and decomposition of complexes. The residual masses of complexes 1 and 2 were 0.96% and 1.97%, respectively. The lower residual mass shows that complexes 1 and 2 can be cleanly evaporated and not decomposed. The temperature of 50% ...
