New Findings from Materials and Energy Research Center in the Area of Bone Research Reported

June 6, 2014



By a News Reporter-Staff News Editor at Health & Medicine Week -- Investigators publish new report on Bone Research. According to news reporting out of Karaj, Iran, by NewsRx editors, research stated, "The present paper deals with the effect of adding SiC, TiO2 and SiO2 nanoparticles on setting time, mechanical strength and hydraulic reactions of calcium phosphate cements (CPCs). The initial and final setting times of CPC increased by adding both nano-SiC and nano-TiO2 additives but decreased by using nano-silica."

Our news journalists obtained a quote from the research from Materials and Energy Research Center, "Nano-titania and nano-silica had great effect on compressive strength of as-set CPC whereas slight changes were found by using nano-SiC. Although a sharp increase in compressive strength of all cements was observed by soaking them in physiological solution, the soaked additive-free cements and nano-SiO2-added ones exhibited the greatest strength values. The results showed that adding these nano-additives did not influence on conversion rate of cement reactants to apatite phase during soaking in physiological solution period but the morphology of the formed phase was almost different."

According to the news editors, the research concluded: "Overall, the results determined that nano-SiO2 and nano-TiO2 particles were appropriate additives to improve short-term mechanical strength of CPCs a(s-set CPCs), though nano-SiO2 was found more effective because it improves the long-term mechanical strength of CPC (after soaking) too."
