SummaryCalcium overload, characterized by an abnormal cytoplasm accumulation of free calcium ions (Ca2+), is a widely recognized cause of damage in numerous cell types and even of cell death. This undesirable destructive process can become a new tool applicable to cancer treatment. Herein, on th...

Calcium oxide/water reaction is a promising thermochemical energy storage system owing to its high reaction enthalpy, wide availability at low cost, and favorable reaction temperature. In this research work, a calcium carbonate material was developed, featuring nano-order diameter with a silane ...

The role of calcium oxide on ash fusion properties was investigated in this work by molecular dynamics simulations and thermodynamics calculations. The variation of volume was used to identify the melting points, which was compared with the liquidus temperature calculated by the FactSage codes. ...

Calcium manganese oxides have captured strong scientific interest in recent years due to exceptional catalytic activities, inexpensive synthesis methods, and constitution of earth abundant and environmentally benign elements. In particular, the catalytic properties of Ca–Mn–O systems have been...

The present work proposes the synthesis of nanocrystalline calcium oxide by sonication assisted reverse emulsion technique. The synthesized and the commercially available calcium oxide were characterized by various techniques. The prepared material possesses 1.53 times higher specific surface ar...

In order to enhance the extraction yield of sludge protein, electron beam irradiation (EBI) pretreatment in the presence of calcium oxide was investigated. The influences of the moisture content of sludge, dose and calcium oxide additive amount on the extraction yield have been studied. The expe...

In the present work, the formation kinetics of hydroxyapatite Ca10(PO4)6(OH)2 during ball milling of mixtures of calcium phosphates with calcium oxide or calcium hydroxide was studied. The conversion degrees of reaction mixtures containing calcium dihydrogenphosphate/dicalcium phosphate/tricalci...

One of the main problems in large-scale biodiesel production is selection of suitable and economically viable heterogenous catalyst. This research work focuses on preparation of calcium oxide (CaO) as a catalyst for the effective conversion of waste cooking oil (WCO) to biodiesel in pilot plant....

While laser melting, deposition, and annealing of semiconductor thin films are well-established, pulsed laser processing of bulk semiconductor material powders has been minimally investigated. This work investigates nanosecond pulsed laser melting of bismuth telluride, a common thermoelectric ma...

Bismuth oxide – titanium dioxide composite materials were produced by pulsed DC reactive magnetron sputtering onto two types of commercially available titanium dioxide nanoparticles. The use of an oscillating bowl enabled deposition of bismuth oxide uniformly onto loose powders, in contrast to ...

Beryllium oxide in the forms of either single crystals (pristine, additively-colored) or hot-pressed ceramic samples was studied in the energy range of 1.2–6.2 eV using both the thermoluminescence (TL) and steady-state X-ray induced luminescence (XRL) techniques. The XRL emission spectra were r...

Preliminary results investigating the microstructure, bonding and effect of beryllium oxide formation on retention in the JET ITER-like wall beryllium tiles, are presented. The tiles have been investigated by several techniques: Scanning Electron Microscopy (SEM) equipped with Energy Dispersive ...

HypothesisThe surface charging and adsorption properties of beryllium oxide follow the same principles as the properties of other metal oxides.

Room temperature polarized Raman scattering and infrared reflectance spectra of a chrysoberyl single crystal have been measured. The IR spectra interpretation was aided by a Kramers-Krönig analysis. Thirty-one out of 36 theoretically expected Raman active bands have been identified and assigned....

The recent report of marketing of radioactive chrysoberyl cat’s-eyes in South-East Asian markets has led us to use an indirect method to estimate the threat to health these color-enhanced gemstones may pose if worn close to skin. We determined the impurity content of several cat’s-eye chrysobe...

Trace element abundances in three indicator minerals (corundum, chrysoberyl, and zircon grains) from the western Mamfe gem placers, as determined by LA-ICP-MS analytical techniques, are shown to be sensitive to their crystallization conditions and source rock types.Corundum is dominantly compose...

Gahnite (ZnAl2O4), chrysoberyl (BeAl2O4) and beryl (Be3Al2Si6O18) have been found as accessory minerals in the external, highly fractionated, leucogranitic unit within the Hercynian reversely zoned Belvís de Monroy pluton (westernmost part of the Montes de Toledo batholith, Cáceres, Spain). Th...

Cr3+ diffusion in chrysoberyl (BeAl2O4) irradiated by H+ ions and electrons has been studied and compared with diffusion in non-irradiated samples. Chrysoberyl crystals were irradiated with 6 MeV H+ ions to fluencies of 1×1016 cm–2 for 25 min and with 10 MeV electrons to fluencies of 2×1017 c...

Two new barium iron pnictide–selenides, Ba2FeSbSe5 and Ba2FeBiSe5, were synthesized by a high-temperature solid-state route and their crystal structures were determined using single crystal X-ray diffraction. Both compounds are isomorphic to the high pressure phase Ba3FeS5 and crystallize in th...

The new ternary selenide Ba9Fe4Se16 has been synthesized from the reaction of appropriate amounts of elements at high temperature in a silica sealed tube. The compound crystallizes in the tetragonal space group I41/a with a=10.0068(3) Å and c=35.6415(9) Å, Z=4. It is an isostructural compound to...
