Calcium is an essential element for our living. Different calcium species show interesting interplay in our body. A slow accumulation of calcium oxalate species in the body turns out to be painful as it forms stone in the kidneys and gall bladder. Therefore extraction of different calcium specie...

Chromium forms part of numerous processes and its unsafe disposal increases the risk of pollution of soils and aquatic systems, especially hexavalent chromium. This paper deals with the behavior of calcium aluminate cement (CAC) in presence of Cr6+ (0.5, 1.0 and 2.5%) as potassium dichromate (K2...

An understanding of the factors controlling calcite dissolution is important for modeling geochemical cycles and impacts of greenhouse gases on climate, diagenesis of sediments, and sedimentary rocks. It also has practical significance in the investigation of behavior of carbonates in petroleum ...

The available experimental structures containing a dichromate dianion were gathered from the ICSD (Inorganic Crystal Structure Database) and CSD (Cambridge Structural Database) databases. The geometrical parameters show considerably wide range in bond lengths and bond angles. The Cr–O–Cr angle...

This paper describes the development of HPLC method for simultaneous estimation of paclitaxel and vinorelbine tartrate loaded in dual drug liposomes, using quality by design (QbD) approach. The main objective was to identify the robust chromatographic conditions where an adequate separation of t...

Asymmetric synthesis of enantiopure cuparenoid sesquiterpenes (R)-α-cuparenone, (S)-cuparene and a formal synthesis of (R)-β-cuparenone was presented in this article. Meinwald rearrangement of an enantiopure trisubstituted 2,3-epoxy alcohol derivative was the key reaction employed to construct...

The title host compound (R,R)-(−)-2,3-dimethoxy-1,1,4,4-tetraphenylbutane-1,4-diol 3, when recrystallized from each of the isomeric xylenes and ethylbenzene, formed a 2:1 host:guest complex in each instance. Competition experiments where 3 was recrystallized from various equimolar binary, ternar...

(R)-(+)-3-aminoquinuclidine was used in the synthesis of [(R)-C7H16N2][CuCl4] (1) and [(R)-C7H16N2][CuBr4] (2), which both contain similar [CuX4]2- anions (X = Cl or Br). The structures of the two compounds were determined using single-crystal X-ray diffraction. The use of enantiomerically pure ...

Organic single crystal of p-Toluidinium l-Tartrate (PTLT) was grown from aqueous solution by slow evaporation technique. X-ray diffraction analysis confirmed the crystal structure and high resolution XRD showed the crystalline perfection of the grown crystal. UV–vis spectral analysis revealed t...

Background Although pharmacotherapies are available for alcohol (EtOH) or tobacco use disorders individually, it may be possible to develop a single pharmacotherapy to treat heavy drinking tobacco smokers by capitalizing on the commonalities in their mechanisms of action.Methods Female alcohol-p...

In this study, we are interested by the caesium-tin mixed salt of 1-vanado-11-molybdophosphoric acid (CsSnPMo11VO40) with Cs/Sn ~ 1, micro and mesoporous material with a large specific surface area and a good thermal stability. Caesium atoms in Cs3HPMo11VO40 are partially substituted by tin in o...

Over the past decade, sodium monofluorophosphate (Na-MFP) gained attention as inorganic self-healing agent on Blast Furnace Slag Cement (BFSC) products. Recent experimental studies revealed the recovering effect of Na-MFP on the microstructure of carbonated BFSC pastes with respect to their fros...

Manganese monofluorophosphate : a new classe of corrosion inhibitors. The preparation of manganese monofluorophosphate by the process of Lange was investigated. To characterize the resulting compound, analytical techniques including infra-red spectroscopy (IR), Thermogravimetric Analysis (TGA) a...

BackgroundMouthrinses containing potassium salts have been shown to be effective for the relief of dentinal hypersensitivity (DH) when used adjunctively to toothbrushing with a nonsensitivity toothpaste.

The effect of moderate Fe overload in the diet and its interaction with phytate, and/or yacon flour (YF), recognized as an inhibitor, and facilitator, of Fe absorption, respectively, was evaluated in healthy rats. For this purpose the following parameters were analyzed: (1) apparent iron (Fe), c...

Two experiments evaluated the additivity of phytate content and coefficient of total tract apparent digestibility (CTTAD) of phosphorus (P) in wheat-barley (WB) and corn (C) when soaked (exp. 1) or fed dry to pigs (exp. 2) in combination with or without microbial phytase (1250 FTU/kg as-fed). In...

At the Department of Energy (DOE) managed Savannah River Site (SRS), uranium and other heavy metals continue to pose threats to the ecosystem health and processes. In the oxic soil of this site, uranium is present primarily as soluble salts of the uranyl ion (i.e., U(VI) or UO22+). Although UO22...

Flame retardant cotton fabrics were prepared based on 3-aminopropyl triethoxysilane (APTES) and sodium phytate through layer-by-layer assembly. The structure, surface morphologies before and after burning, flame retardant and thermal degradation properties of prepared cotton fabrics were examine...

Chitosan was added to cotton fabrics coated with sodium phytate and 3-Aminopropyl triethoxysilane (APTES) to further enhance the fire retardant property by the layer-by-layer (LBL) assembly. The surface morphologies before and after flaming and structure of coated cotton fabrics were evaluated b...

Chitosan nanoparticles have attracted considerable attention as a potential carrier for food and pharmaceutical applications. Herein, using natural sodium phytate as a gelation agent, we developed a new type of green and biocompatible chitosan nanoparticles. We discovered that the chitosan-sodiu...
