Nitrogen dioxide (NO2), as a typical threatening atmospheric pollutant, is hazardous to the environment and human health. Thus, the development of a gas sensor with high response and low detection limit for NO2 detection is highly important. The highly ordered mesoporous indium trioxide (In2O3) ...

Raman measurements were carried out on aqueuos indium nitrate solutions containing different additives (NaNO3, HNO3 and NaOH), on a crystalline hydrate In(No3)3·3H2O, and on its melt. Band envelope fitting in the region of InO stretching vibrations (350 to 550 cm−1 yielded component bands whi...

Titanium oxide coupled with different amount of indium oxides were studied for production of hydrogen under visible light irradiation from water–methanol solution. The photocatalysts were prepared by co-precipitation and characterized by surface area and pore analysis, X-ray diffraction, field ...

S-Nitrosothiols (RSNOs) such as S-nitrosoglutathione (GSNO) are known to produce nitric oxide (NO) through thermal, photolytic, and metal ion-promoted pathways, which has led to their increasing use as exogenous sources of therapeutic NO. Despite the burgeoning NO release applications for RSNOs,...

The use of phase change materials (PCMs) is one of the pathways for the storage of temporarily excessive energy from natural sources (solar) and industry for use at a more suitable later time. One of the materials with a high energy storage density is sodium acetate trihydrate (SAT), on which se...

In this study, preparation of photosensitive indium niobate (InNbO4) gel films by using a chemical modification reagent and their characteristics were investigated. In the electronic absorption spectra of the InNbO4 gel films, the absorption peak assigned a chelate ring was observed at 340 nm, t...

The use of red mud as a support material was evaluated in this study to develop a novel bimetallic catalyst for highly reactive and selective nitrate removal from water and wastewater. The catalyst was optimized for the selection of promoter metal (i.e., Sn, Cu, In, and Zn) and then for noble me...

Lead Indium Niobate, Pb(In0.50Nb0.50)O3 (PIN) is a complex perovskite that exhibits Relaxor (R) characteristics. In this study, we report the synthesis of phase-pure compositions in the system Pb[(In0.50−xFex)Nb0.50]O3 by sol–gel method and discuss the influence of isovalent substitution of Ind...

A thermogravimetric study of the kinetics of thermal nuclei formation and growth has been carried out for the dehydration and decomposition of single crystal strontium permanganate trihydrate, cadmium permanganate hexahydrate, and calcium permanganate pentahydrate. The isothermal dehydration of ...

Dietary guidelines published in the past two decades have acknowledged the beneficial effects of myricetin, an important and common type of herbal flavonoid, against several human diseases such as inflammation, cardiovascular pathologies, and cancer. An increasing number of studies have shown th...

Dried leaves of Licania densiflora yielded five myricetin glycosides: myricetin 3′-methylether-3-O-glucoside (1), myricetin 3′-methylether-3-O-galactoside (2), myricetin 4′-methylether-3-O-rhamnoside (3), myricetin 3′,5′-dimethylether-3-O-glucoside (4), and myricetin 3′,5′-dimethylether-3...

Antioxidant activity of myricetin-3-o-galactoside and myricetin-3-o-rhamnoside, isolated from the leaves of Myrtus communis, was determined by the ability of each compound to inhibit xanthine oxidase activity, lipid peroxidation and to scavenge the free radical 1,1-diphenyl-2-picrylhydrazyl. Ant...

Preparation and characterization of (triphenylphosphine)ruthenium complexes bearing N,O,N′-tridentate ligands, [(L1)RuCl(PPh3)2](BF4) (L1 = 2-[(2-pyridylmethoxy)methyl]pyridine), 1), [(L2)RuCl(PPh3)2](BF4) (L2 = 8-(2-pyridylmethoxy)quinoline, 2) and [(L3)RuCl2(PPh3)] (L3 = 2-[(2-pyridylmethoxy)...

FeCl3·6H2O catalyses the direct conversion of ketones to amides via Beckmann rearrangement in the presence of hydroxylamine hydrochloride in good to excellent yields. No additional organic solvent is required. This solid phase reaction involves in situ formation of oxime, cleavage of C–C bond ...

Synthesis of semiorganic material, triphenylphosphine oxide cadmium iodide (TPPOCdI), is reported for the first time. Employing the temperature reduction method, a crystal of size 16×7×6 mm3 was grown from dimethyl sulfoxide (DMSO) solution. Three dimensional crystal structure of the grown cry...

Based on the features of its crystallization, racemic 3-(2,3-dimethylphenoxy)propane-1,2-diol 2, the synthetic precursor of the chiral drug xibenolol 1, was resolved into pure enantiomers by the direct method of entrainment.
