Studies in the Area of Nanoparticles Reported from Vanderbilt University

March 7, 2014



By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Nanoparticles. According to news originating from Nashville, Tennessee, by NewsRx correspondents, research stated, "Hydrolysis and condensation of VO(Oi-Pr)(3) within inverse micelles containing aqueous ammonia catalyst is conducted under different reaction conditions as a synthesis strategy for preparing VO2 nanoparticles having average diameter < 100 nm."

Our news journalists obtained a quote from the research from Vanderbilt University, "Sol-gel processing of VO(Oi-Pr)(3) to form VxOy gel particles is controlled by varying NH3(aq) concentration and using oleic acid or acetic acid pre-treatments. Isolated VxOy gel nanoparticles are reduced to VO2 nanoparticles by thermal annealing, although annealing conditions must be optimized for each batch of gel particles."

According to the news editors, the research concluded: "VO2 nanoparticles of average diameters 24 or 70 nm prepared by this method show an expected hysteretic semiconductor-to-metal phase transition near 68 A degrees C."
