This study investigated the effects of NaCl replacers (KCl, CaSO4, and MgSO4) on the quality and sensorial properties of pork patty. In the characteristics of spray-dried salt particles, KCl showed the largest particle size with low viscosity in solution. Meanwhile CaSO4 treatment resulted in the smallest particle size and the highest viscosity (p<0.05). In comparison of the qualities of pork p...
Membrane scaling during the treatment of aqueous solutions containing sparingly soluble salts by direct contact membrane distillation (DCMD) was investigated. The results reveal that membrane scaling caused by CaSO4 was more severe than that by CaCO3 or silicate. However, under the experimental condition used in this study and at feed and distillate temperature of 20 C and 40 C, respectively, C...
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...
Fine powders of brushite CaHPO4·2H2O, ardealite Ca(HPO4)x(SO4)1−x·2H2O (Ca(HPO4)0.5(SO4)0.5·2H2O), and calcium sulfate dihydrate CaSO4·2H2O—all containing sodium chloride NaCl as a reaction by-product—were synthesized from 0.5 M aqueous solution CaCl2, hydrophosphate Na2HPO4 and/or Na2SO4. Powder (Ca(HPO4)0.5(SO4)0.5·2H2O) was by precipitation CaCl2 mixed-anionic simultaneously the hydrogen pho...
Calcium sulfate (CaSO4) is one of the most common evaporites found in earth’s crust. It can be as four main variations: gypsum (CaSO4∙2H2O), bassanite (CaSO4∙0.5H2O), soluble anhydrite, and insoluble anhydrite (CaSO4), being key difference hydration state mineral. Naica giant crystals’ growth starts from a supersaturated solution delicate thermodynamic balance close to equilibrium, where form n...
دو فسفرcaso4:dy وcaso4:tm به دلیل حساسیت بالا، روش تهیه آسان و مقاومت شیمیایی خوب خود کاربرد وسیعی در دزیمتری تابش پیدا کردند. سپس محققان اثر ناخالصی های دیگر مانند pb،mn،ag و ...را بر روی پاسخ کریستال caso4:dy بررسی کرده اند. در پایان نامه مرجع [25] کریستال های caso4:dy,mn و caso4:tm,mn ساخته شده و خواص ترمولومینسانس و دزیمتری آن ها بررسی شده است. این پژوهش در ادامه کار مرجع [25] است. و به بر...
Many soil amendments are used to remediate paddy soils polluted with heavy metals, including arsenic (As) and lead (Pb). This study was conducted assess the efficacy of three inorganic amendments, such as calcium carbonate (CaCO3), sulfate (CaSO4), ferrous (FeSO4), on As Pb co-contaminated soils. The were applied alone and/or in combinations compare theirs for stabilization rice growth. In addi...
This study discusses strength deterioration during the curing process of fly ash geopolymer and the use of CaSO4·2H2O (gypsum) as a deterioration remedy when the ash was synthesized using a 10M NaOH and Na-silicate solution. The strength decline was mainly due to the widespread formation of nanometer-sized cracks that were related to excessive Na and Si concentrations at an early age. Use of 2 ...
