Oxide dispersion strengthened (ODS) steels with different contents of zirconium (denoted as 16Cr ODS, 16Cr-0.3Zr ODS and 16Cr-0.6Zr ODS) were fabricated to investigate the effects of Zr on strengthening mechanism of Al-alloyed 16Cr ODS steel. Electron backscatter diffraction (EBSD) results show that the mean grain size of ODS steels could be decreased by Zr addition. Transmission electron micro...

The application of nanoparticle drug formulations, such as nanoliposomal doxorubicin (Doxil), is increasingly integrated in clinical cancer care. Despite nanomedicine's remarkable potential and growth over the last three decades, its clinical benefits for cancer patients vary. Here we report a non-invasive quantitative positron emission tomography (PET) nanoreporter technology that is predictiv...

Raman spectroscopy has been used as a local probe to characterize the structural evolution of magnetron-sputtered decorative zirconium oxynitride ZrOxNy films which result from an increase of reactive gas flow in the deposition The lines shapes, the frequency position and widths of the Raman bands show a systematic change as a function of the reactive gas flow (a mixture of both oxygen and nitr...

The influence of zirconium on the grain refinement of Al 6063 alloy has been experimentally investigated. The microstructure and macrostructure of the refined alloy were investigated. The experimental results reveal that, the coarse dendrites in the microstructure of the alloy are effectively refined with the addition of zirconium to the melt prior to solidification. Grains of Al 6063 alloy can...

Porous zirconium alginate beads as a novel adsorbent were prepared for fluoride removal and characterized by SEM, FTIR, TG, EDX and XPS. The effect of solution pH, adsorbent dose, initial fluoride concentration, contact time, medium temperature and the coexisting ions on adsorption capacity of fluoride ion has been studied. The presence of HCO3 , SO4 2and PO4 3had a large negative impact on flu...

Objective: The aim of the current study was to evaluate efficacy addition zirconium oxide (ZrO2), titanium oxide(TiO2), and silica (SiO2) nanoparticles cold-cured soft liner on adhesion Candida albicans (CA). Material andMethods: Fifty-four patients had been selected divided into three groups according modification linerwith ZrO2, TiO2, SiO2 (18 each of). Each patient received maxillary complet...

Abstract Herein, we reported the facile synthesis of zirconium oxide (ZrO 2 ) nanoparticles from an imidazole based organic precursor followed by calcination 750 °C in thermostat. The bonding properties as‐synthesized were examined FTIR and Raman spectroscopy. X‐Ray Diffraction (XRD) analysed phase formation nanoparticles, spherical‐shaped Field Emission Scanning Electron Microscope (FESEM) Tra...

First principles density functional theory calculations are carried out to investigate the scaling trends of band offsets at model silicon/zirconium silicate interfaces. Owing to the d character of zirconium silicate conduction bands, the band gap and band offset are shown to decrease as the zirconium concentration is increased. Since the valence band character of silicates remains unchanged re...

Nanocomposites of (CMC-PAA-ZrC) made with different nano zirconium carbide percentages by casting method (0, 1.5, 3, 4.5, and 6) wt%. The results showed that FTIR spectra shift in peak position change shape intensity, compared pure (CMC-PAA) blend. Microscopic photographs show a clear difference the samples when increasing proportions nanoparticles, concentration NP reached 6% wt, nanoparticles...

Aims: To investigate the effect of adding nanoparticles on compressive strength alginate impression material. Materials and Methods: In this study, two types were added to materials: silver zirconium oxide at four concentrations: 0.5 %, 1%, 2%, 5% by weight. Compressive was tested for 45 samples made according American Dental specification no.18 Results: The addition did not alter material, whe...
