Nickel is quantitatively retained by tetradecyldimethylbenzylammonium 2-nitroso-1-naphthol-4-sulfonate in microcrystalline naphthalene in the pH range 7.2–11.8 from a large volume of aqueous solutions of various alloys and biological samples. After filtration, the solid mass consisting of the n...

A highly selective, sensitive, rapid and economical differential pulse polarographic method has been developed for the determination of trace amount of tin in various standard alloys and environmental samples after adsorption of its 2-nitroso-1-naphthol-4-sulfonic acid-tetradecyldimethylbenzylam...

Synergism using the title metal extracting agents has been observed for bismuth. Thermodynamic parameters of the extraction process were determined by the temperature coefficient of extractability. The extraction of bismuth from HClO4 by dinonyl naphthalene sulfonic acid (HDNNS) and the mixed li...

High throughput screening (HTS) techniques are required for the fast hit inhibitors selection in the early discovery process. However, in Beta-secretase (BACE1) inhibitors screening campaign, the most frequently used methoxycoumarin based peptide substrate (M-2420) is not widely applicable when ...

The production of dye intermediates made from naphthalene compounds such as 6-nitro-1-diazo-2-naphthol-4-sulfonic acid (6-nitro-1,2,4-Acid) caused a major environmental concern, mainly due to their nature of being highly toxic concentrated organics. In this work, an enhanced Fenton process integ...

Degradation of naphthalene dye intermediate 1-diazo-2- naphthol-4-sulfonic acid (1,2,4-Acid) by Fenton process has been studied in depth for the purpose of learning more about the reactions involved in the oxidation of 1,2,4-Acid. During 1,2,4-Acid oxidation, the solution color initially takes o...

The kinetics of naphthalene-2-sulfonic acid (2-NSA) adsorption by granular activated carbon (GAC) were measured and the relationships between adsorption, desorption, bioavailability and biodegradation assessed. The conventional Langmuir model fitted the experimental sorption isotherm data and in...

Polyaniline (PANI) nanocomposites containing gold nanoparticles (AuNPs) dispersed on reduced graphite oxide (RGO) were chemically prepared in the presence of 2-naphthalene sulfonic acid (NSA) as a dopant. The surface morphology of the synthesized composites was studied using transmission electro...

The current investigation was carried out to estimate the requirement of dietary zinc for fingerling Labeo rohita (6.3 ± 0.09 cm; 2.12 ± 0.08 g) by feeding casein-gelatin based seven isonitrogenous (350 g kg−1 crude protein) and isoenergetic (16.7 kJ g−1 gross energy) diets with incremental le...

In mammalian blood plasma, serum albumin acts as a transport protein for free fatty acids, other lipids and hydrophobic molecules including neurodegenerative peptides, and essential metal ions such as zinc to allow their systemic distribution. Importantly, binding of these chemically extremely d...

Flavonoids are commonly occurring polyphenolic compounds with a wide array of bioactive properties, including its positive role on osteoblast differentiation and bone formation. Their profound ability to chelate various metal ions supported its candidature as a novel biomaterial for tissue engin...

The objective of this work was to develop solid dosage forms to improve zinc nutrition in high-risk populations. Powders containing zinc (17 mg/g) were obtained through co-crystallization in sucrose matrix with high encapsulation efficiency (98%). Co-crystallized powders showed water activity (0...

Aqueous rechargeable metal-ion batteries have become potentially advantageous for the integration of renewable energy sources into the electric power grid thanks to their high rate capability, low cost, environmental friendliness, and intrinsic safety. In this work, we tried to improve the elect...

In zinc production, the purity of incoming zinc solution is of great importance. The presence of cobalt in the electrolyte used for zinc production lowers the current efficiency of zinc deposition and affects the purity of the zinc product. For this reason, cobalt must be removed from the electr...

Three industrial waste materials were examined in terms of their elemental and phase compositions, leaching behaviour in sulphuric acid solutions followed by solution purification and zinc electrowinning. Two dusts being mixtures of metallic zinc and zinc oxide of various proportions and zinc as...

For industries around the world, the hydrometallurgical roast–leach–electrowin process is the most common means of producing zinc metal. Dechlorination from the highly-concentrated zinc sulfate electrolyte is of vital importance to the zinc industry. In a recently published work, we innovative...

Single crystal of ammonium potassium zinc sulfate hexahydrate hereafter (AKZSH) was successfully grown by the slow evaporation technique. The crystal structure was calculated for the as-grown crystal using single crystal diffraction, yet the crystal structure was confirmed by X-ray powder diffra...

Thirteen new N-aryl 1,2,3,4-tetrahydroquinoline compounds (4a–f, 6a–c, and 8a–d) were synthesized and evaluated for antitumor activity and drug-like properties. Compound 4a exhibited high inhibitory potency with low nanomolar GI50 values of 16–20 nM in cellular assays, including excellent ac...

Structural optimizations of the prior lead 1a led to the discovery of a series of N-aryl-6-methoxy-1,2,3,4-tetrahydroquinoline derivatives as a novel class of tubulin polymerization inhibitors targeted at the colchicine binding site. The most active compound 6d showed extremely high cytotoxicity...
