Key words: mineral plumbomicrolite; tantalum; niobium; acid leaching; radioactivity; solvent extraction Cite this article as: S M MASLOBOEVA, L G......
">The effects of 3 chairside polishing kits and mechanical brushing on the surface roughness of 3 different acrylic denture base resins were compared. Acrylic denture base resins (auto-polymerizing, heat-polymerizing, injected heat-polymerizing resins) were examined after a tungsten carbide bur, and after chairside polishing using 3 polishing kits and pumice. The specimens were subjected to mechanical......

SYNTHESES AND ADSORPTION PROPERTIES OF POLYMER RESINS CONTAINING BENZIDINE AND ITS DERIVATIVES张超灿,谢海安,庞金兴,李曦,熊传溪摘 要:<正> Three chelating resins were.... Theadsorption properties of the resins for Au (Ⅲ), Pd (Ⅱ). Pt(Ⅳ),Hg(Ⅱ) .Cu(Ⅱ),Pb(Ⅱ) and Zn(Ⅱ) were also investi-gated. The results show that the resin incorporating o-diani-sidine exhibits high affinity for Au......
, Changsha 410083, China;2. School of Geo-sciences and Info-physic, Central South University, Changsha 410083, China)Abstract:A new impregnated diamond bit was designed to solve the slipping problem when impregnated diamond bit was used for extra-hard, compact, and nonabrasive rock formation. Adding SiC grits into matrix, SiC grits can easily be exfoliated from the surface of the matrix due to weak......
