Sintering and Foaming of Barium Silicate Glass Powder Compacts
The manufacture of sintered glasses and glass-ceramics, glass matrix composites, and glass-bounded ceramics or pastes is often affected by gas bubble formation. Against this background, we studied sintering and foaming of barium silicate glass powders used as SOFC sealants using different powder milling procedures. Sintering was measured by means of heating microscopy backed up by XPD, differen...
متن کاملSynthesis, in vitro evaluation and biological studies of copper-containing 58S bioactive glass
Cu-substituted 58S bioactive glasses (0-10%mol CuO) were synthesized by sol-gel method and the effect of copper substitution for calcium on their biodegradability, bone-like apatite formation, cell proliferation, alkaline phosphatase activity of M3T3-E1 osteoblast cells and antibacterial efficiency were investigated. The results of x-ray diffraction (XRD) and Fourier transform infrared spectros...
متن کاملStudies on Copper Metabolism*
The results of studies on certain enzymes, hemin chromoproteins, and iron and copper in the tissues of normal, copper-deficient, and iron-deficient swine are reported in this paper. It has been suggested that the enzymes cytochrome oxidase (l-3), uricase (4), tyrosinase (5), plasma polyphenol oxidase (coeruloplasmin) (6), glutathione oxidase (7), and butyryl coenzyme A dehydrogenase (8) either ...
متن کاملStudies on Copper Metabolism. Xix
Ferrokinetic studies were performed in three copper-deficient swine and the results have been compared with similar studies in 18 normal pigs. The mean value for the plasma iron turnover rate in the deficient swine was 1.76 mg./kg. day; for the red cell iron incorporation rate, 1.24 mg./kg. day; for the red cell iron turnover rate, 1.18 mg./kg. day; for the red cell life span, 13 days. Correspo...
