Development and evaluation of reparative tricalcium silicate-ZrO2-Biosilicate composites
(2020-01-01)
Biosilicate is a bioactive glass–ceramic used in medical and dental applications. This study evaluated novel reparative materials composed of pure tricalcium silicate (TCS), 30% zirconium oxide (ZrO2) and 10 or 20% ...
Effect of silver nanoparticles on physicochemical and antibacterial properties of calcium silicate cements
(2016-09-01)
Mineral trioxide aggregate (MTA) and Portland cement (PC) are calcium silicate cements. They have similar physicochemical, mechanical and biological properties. The addition of zirconium oxide (ZrO2) to PC provides ...
Inorganofunctionalization of Ti(IV) and Zr(IV) on the MCM-41 Surface and its Interaction with a Mixed Valence Complex to use as Isoniazid Sensing
(2021-01-01)
In this work, it describes the preparation of Titanium and Zirconium functionalized MCM-41 and subsequent chemical modification with nickel hexacyanoferrate. The obtained materials (MTiNiH and MZrNiH) were characterized ...

Strontium zirconate heterogeneous catalyst for biodiesel production: Synthesis, characterization and catalytic activity evaluation
(ELSEVIER SCIENCE BVAMSTERDAM, 2012)
Strontium zirconate oxide was synthesized by co-precipitation and the citrate route and was evaluated as a heterogeneous catalyst for biodiesel production. The catalyst samples were characterized by XRD, FTIR, and TG, and ...
Effect of Different Radiopacifying Agents on the Physicochemical Properties of White Portland Cement and White Mineral Trioxide Aggregate
(ELSEVIER SCIENCE INCNEW YORK, 2012)
Introduction: The aim of this study was to evaluate the pH, calcium ion release, setting time, and solubility of white mineral trioxide aggregate (WMTA) and white Portland cement (WPC) combined with the following radiopacifying ...
Physicochemical, biological, and antibacterial evaluation of tricalcium silicate-based reparative cements with different radiopacifiers
(2021-02-01)
Objective: To evaluate tricalcium silicate-based (TCS) experimental materials, associated with zirconium oxide (ZrO2), calcium tungstate (CaWO4) or niobium oxide (Nb2O5) radiopacifiers, in comparison with MTA Repair HP ...
