This work studied the effect of nanoporous alumina in acute cellular response in an in vivo model. Nanoporous alumina membranes, with pore size diameters of 20 and 200 nm, were fabricated by anodic oxidation of aluminium. The membranes were thereafter characterized in terms of pore size distribution and chemical composition. To evaluate acute inflammatory response, the membranes were implanted ...
A proenzyme (hereafter propeptidase), with a high activity on N-acetyl-L-tyrosine ethyl ester, was found associated with proelastase through several steps of purification. Propeptidase is distinct from chymotrypsinogen A as shown by its electrophoretic mobility and its high resistance, in the activated form, to inhibition by r.-1-tosylamido-Z-phenylethyl chloromethyl ketone. Evidence indicates ...
A comparative analysis of the effectiveness deflocculating effect Russian and international polycarboxylate ethers additives on rheological properties high-alumina matrix suspensions is presented in this article. For production functional systems, submicron activated α-alumina modified high alumina cement are used ratio 80:20 90:10 wt. %, respec-tively. fluidity with a moisture content 20% carr...
The aim of this investigation is obtaining WC-Co composite powder from WO3 and Co3O4 by in-situ and carbothermic reduction method using activated carbon as a reducing agent. In this study, cobalt and tungsten oxide powders with 17% carbon (30% more than stoichiometric value) were mixed by ball-milling under atmosphere of argon for 20 hours. Differential Thermal Analysis (DTA) and Therm...
