Corrosion inhibition of aluminum alloy AD31 (AA6063) in aggressive chloride-containing acidic media by cerium nitrate (III), sodium metavanadate, and mixtures of thereof has been investigated by electrochemical and weight loss techniques. The inhibition effectiveness of cerium ions and cerium-va...
A small addition (≤0.5 wt%) of cerium silicide (CeSi2) to powder metallurgy (PM) commercially pure Ti (CP-Ti), Ti–6Al–4V and Ti–10V–2Fe–3Al (all in wt%) results in substantial microstructural refinement and noticeably improved ductility with marginally improved sintered density. CeSi2 is u...
Pure silicide coating and Y-Ce modified silicide coating were prepared on Ti-6Al-4V alloy by pack-cementation process. The structures as well as the isothermal oxidation behaviors of the coatings were comparatively studied. The results showed that both pure silicide coating and Y-Ce modified sil...
The cerium silicides, Ce5Si3, Ce3Si2, CeSi, CeSi2−y, and CeSi2−x, have been prepared from the elements by mechanochemical processing in a planetary ball mill. Preparation of the cerium silicide Ce5Si4 was unsuccessfully attempted and potential reasons for this are discussed. Temperature and pres...
Lanthanon monosulfides show sernimetallic conductivities with the exception of EuS and YbS, which are insulators, and of SmS, which is an n-type semiconductor with an energy gap of 0.24 eV. Ytterbium monosulfide becomes a p-type semiconductor when doped with sulfur. A new value for the susceptib...
Submicronic well crystallized particles of cerium dioxide have been prepared through a new route: a solvothermal process. The precursor and the solvent are raised up to high temperature and high pressure conditions near the supercritical conditions of the system. The present study is devoted to ...
Cerium oxide (CeO2) nanoparticles (NPs) of diameter 20–100 nm have been successfully immobilized into the cellulose fiber matrices. The in situ synthesis was carried out using a single step hydrothermal technique at low temperature without the aid of linker, binder or retention aid. Paper matri...
There are three main reasons for the study of antimonides, they are the optical [mainly infrared], electrical [mainly Insb; the Gasb/Inas heterojunction] and structural [mainly ordering and spinodal decomposition] properties. These properties, together with the various techniques used to measure...
Externally decorated glassware used for the consumption of beverages, purchased new or sourced second-hand, and including tumblers, beer glasses, shot glasses, wine glasses and jars, has been analysed for Pb and Cd by portable x-ray fluorescence (XRF) spectrometry. Out of 197 analyses performed ...
In the second of a series of interviews with the compounds community, the theme begun in the April issue on antimonides is continued. Editorial board member Tim Phillips of QinetiQ was relieved to learn that his favourite subject was to get an airing. Another centre of antimonide activity is the...
The diffusion of cadmium in both single-crystal and polycrystalline indium antimonide has been studied using radio-tracer techniques. For the single-crystal material the diffusion was found to obey Kick's law. The diffusivity varied with temperature according to the relation D(T) = D0exp(-(...
The ternary rare-earth cadmium antimonides RECd1−xSb2 (RE=La, Ce, Pr, Nd, Sm) were prepared by reaction of the elements at 1000 °C. The presence of Cd defects, previously found for LaCd0.700(5)Sb2 and CeCd0.660(4)Sb2, has been confirmed by single-crystal X-ray diffraction studies for the isotyp...
In this work, we construct a well-designed integrated photocatalyst with massive specific surface area of active sites for high-efficiency photocatalytic splitting water. Taking CdS/Co2P as a case, we first put forward a typical one-step hydrothermal strategy to synthesize cobalt phosphide (Co2P...
Cadmium phosphide (Cd3P2) when synthesized from the direct reaction of cadmium metal salt and tri-octylphosphine (TOP) in presence of sodium metal showed band-gap emissions with engineered band-gap energy in between 2.85 and 2.75 eV. Optical studies showed pronounced quantum confinement effect f...
The contents of 28 trace elements, 17 amino acid were evaluated in muscular tissues (wings, crureus and pectoralis) of chickens in response to arsenic trioxide (As2O3). A total of 200 one-day-old male Hy-line chickens were fed either a commercial diet (C-group) or an As2O3 supplement diet contai...
In the present work we report the enhanced UV light photocatalytic performance of cadmium titanate photocatalyst by MoO3 for Drug pollutant degradation. The nano photocatalyst sample was synthesized employing the Pechini-ultrasonic-hydrothermal route. Therefore, the nano photocatalyst were chara...
Several compositions of calcium stabilized sialon ceramics were synthesized by using nano-size starting powder precursors and spark plasma sintering technique at a relatively low temperature of 1500 °C. The formation of calcium alpha/beta-sialons was investigated for the compositions represente...
Calcium stabilized alpha-sialon ceramic was synthesized using spark plasma sintering (SPS). The size effect of aluminum nitride precursor (1 μm and 50 nm) on the phase analysis, microstructural and mechanical characteristics of the processed sialon was studied. Alongside the size of AlN precurs...
Three new nitrides, Li3Ca2V0.79Nb0.21N4, Li2Ca2.67Nb0.33N3 and Li12Ca9W5N20, were synthesized in sealed niobium tubes using lithium nitride as a flux at temperatures ranging from 800 °C to 1050 °C. In all of these compounds, the transition metals are coordinated tetrahedrally by nitrogen; thes...
A graphitic carbon nitride material with enhanced surface properties has been successfully synthesized from guanidine monohydrochloride used as carbon nitride precursor, and from calcium salts nanoparticles used as templates. The products were characterized by X-ray Diffraction (XRD), chemical a...
