CaSO4: Dy, P is known for its dosimetric characteristics for a very long time now. In this work we have carried out a comparative study on TL intensity of CaSO4: Dy, P, Ce phosphors using two different wet chemical synthesis routes. Nobody seems to have reported this kind of study on CaSO4: Dy, P, Ce 3+ phosphors and as a result it may be regarded as something new. Phosphors were characterized ...

The aim of this study was to evaluate the in vitro and in vivo biocompatibility of artificial bone based on vancomycin loaded mesoporous silica nanoparticles and calcium sulfate composites. In vitro cytotoxicity tests by cholecystokinin octapeptide (CCK-8) assay showed that the 5%Van-MSN-CaSO4 and Van-CaSO4 bone cements were cytocompatible for mouse osteoblastic cell line MC3T3-E1. The microsco...

Mineral scale deposition in near wellbore regions of injection wells is one of the main challengeable issues during the water injection process, which magnifies the importance of robust models in predicting the amount of mineral scale deposition such as calcium sulfate. One of the main challenges of CaSO4 scale is in carbonated reservoirs, in which sensitive behavior is observed in related to t...

The formation of deposits on heat transfer surfaces is the main hurdle in optimum operation of thermal desalination units. It is, therefore, common practice to operate these units i.e. MSF under sub-atmospheric pressure to boil saline water below saturation temperature of which depositions occurs. However this comes with high price-tag for excessive use of energy for pumping. Alternative and en...

Background: Many studies have reported the role of Mesenchymal Stem Cells (MSC) in treating fractures. In case with bone defect, fracture healing needs not only osteogenic but also osteoconductive component (scaffold). Hydroxyapatite calcium sulphate (HA-CaSO4) being widely used as bone void filler, may serve as scaffold for MSC. However, the effect of this scaffold to the viability of MSC has ...

Plaster, made of calcium sulfate hemihydrate (CaSO4•½H2O) and/or γ-anhydrite (CaSO4) is obtained by dehydration gypsum (CaSO4·2H2O) at 100–200 °C. When mixed with water, it dissolves while new crystals precipitate. Plaster's microstructures affect its reactivity and setting properties, but are poorly understood due to confusion between polycrystalline structures in the literature. Through a mul...

Introduction: A previous study indicated that the area fraction of new bone after 6 weeks was greater in cavitary defects treated with calcium sulfate (CaSO4) pellets (mean 14.3%) compared to CaSO4 pellets containing demineralized bone particles (DBM) (10.5%) (p=.035) [1]. The CaSO4-treated defects exhibited a unique pattern of circular lamellae of residual CaSO4 and abundant new trabeculae of ...

2-phosphonobutane-1,2,4-tricarboxylic acid is(pbtc) a member of phosphonate family, and used as corrosion and scale inhibitor in cooling water systems. phosphonocarboxylates as a member of organophosphorus compounds have c-p and p-o bonds in their structures. pbtc is mainly used as carbonate scale inhibitor (caco3), sulphate scale inhibitor (caso4), corrosion inhibitor of low alloyed steel, eff...
