In this study, B modified silicide coatings were prepared on Nb-Si based alloy with Al2O3 or SiO2 inert-filler by pack cementation technology. Both primarily consisted of a (Nb,X)Si2 (Nb,X)B2 + outer layer. After oxidation at 1250 °C for 100 h, the showed good resistance due to formation dense silica. The products coating SiO2, TiO2 and Cr2O3, while that TiO2, HfO2. different may be process the...

TiO2-SiO2 photocatalytic nanostructure film on windshield for self-cleaning purposes was prepared via sol–gel dip-coating method. TiO2 films were prepared on automotive glass pre-coated with a SiO2 layer by a dip-coating method followed by annealing at 500 °C for 30min. The films were characterized using X-ray diffraction XRD and scanning electron microscopy SEM, FE-SEM techniques. The TiO2-SiO...

To understand and clarify the formation mechanisms evolution of complex inclusions in Ti-Ca deoxidized offshore structural steel, industrial steel were systematically investigated. The number density total generally decreased from Ladle Furnace (LF), Vacuum Degassing (VD), Tundish to final product except for Ti Ca addition. major during refining process CaO-Al2O3-SiO2-(MgO)-TiOx CaO-Al2O3-SiO2....

Transition metal (TM)-doped TiO2 films (TM = Co, Ni, and Fe) were deposited on Si(100) substrates by a sol-gel method. With the same dopant content, Co dopants catalyze the anatase-to-rutile transformation (ART) more obviously than Ni and Fe doping. This is attributed to the different strain energy induced by the different dopants. The optical properties of TM-doped TiO2 films were studied with...

This project is an extension of TEM work conducted on a previous AINSE funded project AINGRA08066, and aims to use the TEM, STEM/HAADF, EDS and plasmon imaging facilities at ANSTO to structurally characterize novel supported silver nanoparticle catalysts for ozone abatement, and supported gold catalysts for low temperature CO oxidation. The catalysts, fabricated at the University of Auckland, c...

The development of high-efficiency photocatalysts plays an important role in the application solar energy conversion. Titanium dioxide (TiO2) with anatase crystalline phase is well-known as semiconductor thin layers for cells. This work has constructed a novel TiO2 hollow sphere (HST) 2-step synthesis. first step coating SiO2 template to build core-shell SiO2@TiO2 (CSST). second etching via son...

Abstract Catalysts based on Pd/In were prepared through the wet impregnation method using Al2O3, SiO2, and TiO2 as supports. The impact of synthesis procedure N2 selectivity was studied. Characterization performed X-ray fluorescence scanning electron microscopy–energy dispersive spectroscopy analysis. catalytic performance these materials evaluated for nitrate removal from water in a batch reac...
