analysis showed the presence of complex compounds containing calcium silicate hydrate in the synthesized sorbents.

titanium and its alloy are known as important load-bearing biomaterials. the major drawbacks of these metals are fibrous formation and low corrosion rate after implantation. the surface modification of biomedical implants through various methods such as plasma spray improves their osseointegration and clinical lifetime. different materials have been already used as coatings on biomedical implan...

Pulpal response of four calcium hydroxide liners, MPC 10, MPC 12, Dycal and Pulpdent were tested on primary and permanent teeth with zinc oxide and eugenol (ZOE) and silicate as controls. Responses of the pulps were evaluatedi in Rhesus monkeys, utilizing Class V cavity preparations at 3 days, 5 and 8 weeks. An equivalent number of anterior and posterior teeth were studied for all compounds. Th...

ii iii ABSTRACT This report documents experiments conducted to determine the head-loss characteristics associated with calcium silicate insulation debris accumulated on a sump screen. These experiments were performed under the direction of Los Alamos National Laboratory in facilities operated by the Civil Engineering Department of the University of New Mexico. Experiments confirmed that calcium...

The carbon-cycle significance of soil carbonate fluxes is subject to large uncertainties because it is not clear precisely how much calcium is derived from atmospheric sources compared with that from the chemical weathering of silicate minerals. In the petrocalcic horizon (calcrete) of a Pleistocene soil from the USDA–SCS Desert Project area near Las Cruces, NM, approximately 1.5 g Ca=cm3 has b...

The 1st report1) in a series of these studies, which was deduced from the report by Miyamoto and Takikawa2) that a precipitate of calcium silicate and magnesium silicate formed a semi-permeable membrane at the Pringsheim'a equilibrium point, recognized a formation of the so-called •hCrystal semi-permeable membrane•h also in a common water-insoluble salt (In this case, sodium carbonate and calci...

Objective. The aim of this study was to evaluate the physicochemical properties and bioactivity of two formulations of calcium silicate-based cements containing additives (CSCM) or resin (CSCR), associated with radiopacifying agents zirconium oxide (ZrO2) and niobium oxide (Nb2O5) as micro- and nanoparticles; calcium tungstate (CaWO4); and bismuth oxide (Bi2O3). MTA Angelus was used as control....
