Reusable Nanocatalyst: Zirconia and Sulfated Zirconia
International Letters of Chemistry, Physics and Astronomy, 2014 1,5-benzodiazepines have been synthesized by Nano Zirconia and Nano Sulfated Zirconia in solvent free conditions. Synthesis was carried out by conventional as well as microwave method. Benzodiazepines were synthesized by reacting o-phenylenediamine and few ketones in the presence of catalytic amount of Nanoparticles.

Evaluating dental zirconia [PDF]
Dental Materials, 2019 To survey simple contact testing protocols for evaluating the mechanical integrity of zirconia dental ceramics. Specifically, to map vital material property variations and to quantify competing damage modes.Exploratory contact tests are conducted on layer structures representative of zirconia crowns on dentin.Sharp-tip micro- and nano-indentations were

Advanced Engineering Materials, EarlyView.New features on yttria‐stabilized zirconia after exposure at 1500°C: Newly discovered pyramidal structures on an old material. After exposure at 1550°C on the cross section of YSZ new features, namely pyramidal structures are discovered. These structures grow with time, increase in numbers, appear as singularities, are often arranged in strings, and ...
