Step-wise reaction of CdO, Bi2O3, and Cd(NO3)2·4H2O leads to formation of a novel bismuth oxide nitrate, CdBiO2NO3, which completes the family of bismuthite-like MIIBiO2NO3 oxide nitrates. The new compound is tetragonal, I4/mmm, a = 3.9486(1)Å, c = 14.2235(2)Å; its crystal structure resembles t...

Basic bismuth nitrates, Bi6O6(OH)2(NO3)4·2H2O and Bi6O5(OH)3(NO3)5·3H2O (respectively denoted as BiON-4N and BiON-5N), were easily synthesized by a grinding-assistant room temperature reaction route through carefully tuning NaOH amounts. The plate-like BiON-5N prepared at NaOH/Bi molar ratio o...

Crystals of a novel bismuth tellurium nitrate hydroxide, Bi2Te2O6(NO3)2(OH)2(H2O), with noncentrosymmetric (NCS) structure have been grown in high yield through a hydrothermal reaction using TeO2, Bi(NO3)3·5H2O, and HNO3 as reagents. Bi2Te2O6(NO3)2(OH)2(H2O) exhibits a layered structure consist...

Various Bi2MoO6 (BM)-based heterojunctions have been constructed to enhance the photocatalytic performance, but hydroxide/BM heterojunctions were rarely reported. To illustrate function of hydroxides in the heterojunctions for charge separation and photoactivity enhancement, In(OH)3/BM heterojun...

A stability-indicating high-performance liquid Chromatographic method with on-line clean-up has been developed for the analysis of betamethasone 17-valerate in topical dosage forms. A short pre-column containing 10 μm octadecylsilane mounted into the sample loop position of an injection valve w...

Contrary to some organophosphorus esters (OPs), certain esterase inhibitors including sulfonyl halides, carbamates and phosphinates do not cause axonal neuropathy, but they may exacerbate traumatic and some chemical insults to axons. This phenomenon is referred to as the promotion/potentiation o...

Natural oestrogenic hormones are the appropriate substances for the therapy of climacteric complaints. After oral or parenteral administration, oestradiol valerate, the synthesis compound contained in various commercially available preparations, is completely converted into the natural substance...

Sulfate ions pose a major threat and challenge in the treatment of industrial effluents. The sample of wastewater obtained from a pigment industry contained large quantities of sulfate in the form of sodium sulfate which resulted in high TDS. As the removal of sulfate from pigment industry efflu...

Thermally driven cooling systems are becoming increasingly important as an alternative to the conventional mechanical vapour compression cooling systems. Among these technologies, thermochemical cooling offers a large number of chemical reactions in a wide range of operating conditions, which ca...

Thiourea barium chloride (TBC), Amaranth doped (0.05, 0.1 mM) TBC(ADTBC) crystals were synthesized at room temperature by solvent evaporation process. Structural analysis of TBC and ADTBC were studied using powder XRD, results confirmed that dye got incorporated into the host lattice. Optical an...

In the present work, a synthesis and comparative study on the effect of Zinc (Zn) on thiourea barium chloride (TBC) single crystals has been reported. Crystals of thiourea barium chloride and Zn-doped thiourea barium chloride crystals are prepared using slow evaporation from the saturated soluti...

SummaryBackgroundSkin antisepsis is performed before surgery to minimize the risk of surgical site infections. Chlorhexidine gluconate (CHG) is routinely used in this application, but it may be removed during surgery when prepped areas are exposed to fluid and repeated blotting.

The present research focuses on the corrosion inhibition of a two phases (α-β) brass in 0.5 M H2SO4 solution containing sodium gluconate (SG) and cetyltrimethyl ammonium bromide (CTAB) at different temperatures. The inhibition effect was studied using electrochemical impedance spectroscopy (EI...

Uranium tetrafluoride (UF4) is the most used nuclear material for producing metallic uranium by reduction with Ca or Mg. Metallic uranium is a raw material for the manufacture of uranium silicide, U3Si2, which is the most suitable uranium compound for use as nuclear fuel for research reactors. B...
