Zirconium dioxide has been widely used in dental prosthetics. However, the improper mechanical treatment can induce changes in the microstructure of zirconium dioxide. From the viewpoint of mechanical properties and performance, the phase transitions of ZrO2 from the tetragonal to the monoclinic...

Here we focused on the fundamental study of self-cleaning properties of zirconium dioxide films, including photoinduced alteration of surface hydrophilicity, photocatalytic and photoinduced bactericidal activities. The accent was made on the factors influencing the photoinduced hydrophilic conve...

Zirconium dioxide loaded montmorillonite (ZrO2-MMT) composites have been prepared using an ion-exchange process at room temperature followed by a thermal treatment. The as-prepared composites are used to adsorb Cr3+ ions in the tanning wastewater with a lower initial Cr3+ concentration, reducing...

A thermal quenching effect of luminescence was studied in nanostructured compacts of monoclinic zirconium dioxide obtained by cold pressing of nanopowders. The dependence of PL intensity at 480 nm emission band on temperature was found experimentally. It was established that TL quenching causes ...

In the current research, the effect of nano Zirconium dioxide (ZrO2) on the buckling strength of epoxy resin based composite was studied experimentally before and after applying damage. The nano particles were added to the epoxy resin matrix with 1–4 wt% of the composite. The applying damage to...

The present study highlights the potential application of zinc peroxide (ZnO2) nanomaterial as an efficient material for the decontamination of cyanide from contaminated water. A process patent for ZnO2 synthesis has been granted in United States of America (US Patent number 8,715,612; May 2014)...

Highly porous zinc peroxide nanoparticles were synthesized at ambient conditions following a one-pot wet precipitation method. Subsamples were calcined at various temperatures up to 400 °C. The structural, morphological, optical and chemical features were evaluated by X-Ray diffraction, N2 adso...

Angiogenesis is a process of formation of new small blood vessels from existing vessels and is very critical for proper and rapid tissue healing. As reactive oxygen species (ROS) are known for their ability to promote angiogenesis, in this study zinc oxide (ZnO) and zinc peroxide (ZnO2) nano-par...

In this work the thermodynamical solubility diagrams of zinc and titanium hydroxides were reviewed in order to determine the conditions for maximum degree of phase composition homogenization of precipitates. Experimental investigation of dependency of titanium peroxohydroxide solubility on solut...

Fuel bundle end power peaking in pressure tube heavy water reactors (PT-HWRs), particularly considering advanced reactor fuels (such as thorium-based fuels), was evaluated and a mitigation method was assessed. For bundles containing all the same fuel pellets, power is greatest at the bundle ends...

In this research, the reverse non-equilibrium molecular dynamics is employed to investigate the effect of vacancy and substitutional defects on the thermal transport in thorium dioxide (ThO2). Vacancy defects are shown to severely alter the thermal conductivity of ThO2. The thermal conductivity ...

In this research paper, the thermal transport in thorium dioxide is investigated by using nonequilibrium molecular dynamics. The thermal conductivity of bulk thorium dioxide was measured to be 20.8 W/m-K, confirming reported values, and the phonon mean free path was estimated to be between 7 and...

In this work, a novel experimental method for measurement of radiation emitted by supercritical carbon dioxide (s-CO2) at high pressure and high temperature is presented.
