The synthesis and crystal structures of three heteroleptic complexes Zn(II) Cd(II) with pyridine ligands (ethyl nicotinate (EtNic), N,N-diethylnicotinamide (DiEtNA), 2-amino-5-picoline (2Ampic) are presented. complex [Zn(EtNic)2Cl2] (1) showed a distorted tetrahedral coordination geometry two EtNic ligand units chloride ions as monodentate ligands. Complexes [Zn(DiEtNA)(H2O)4(SO4)]·H2O (2) [Cd(...

Introduction: Recent remote-sensing observations have demonstrated surface-correlated OH/H2O on the regolith of the Moon from highto mid-latitudes [1-3]. The estimated abundances of lunar surface water from the reflectance spectra ranged from 10-5000 ppm [1-3]. Three sources have been suggested: solarwind origin; volatile retention from meteoritic impact; and degassing of indigenous water [1-4]...

The aim of this research is to develop new mordants and a wide range of colors for natural dyeing of silk. In this study, two new erbium(ΙΙΙ) complexes, [Er(AO)(H2O)7](OAc)3 and [Er(AMH)(H2O)6](OAc)3 (AO = acridine orange, AMH = azomethine-H, and OAc = acetate anion), were synthesized, characterized and used as a mordant for the natural dyeing of silk yarns with an aqueous extract of green waln...

Samarium diiodide-water (SmI2-H2O) reagents have emerged as some of the most practical systems enabling reduction and reductive cyclizations of ketyl radicals. Recently, this reaction manifold has been extended to acyl-type radicals generated from cyclic polar carboxylic acid derivatives. However, the relationship between the fundamental electron- and proton-transfer steps in the generation of ...

The colorless salts [C5H10NH2][Au (CN)2], [C4H8NH2][Au (CN)2], [Ph2NNH3][Au (CN)2] H2O and [(n-C3H7)4N][Au(CN)2] H2O have been prepared by evaporation of aqueous solutions of potassium dicyanoaurate and the chloride salt of the appropriate cation. Hydrogen bonding between the cations and the cyano groups of the anions facilitates the formation of structures with strong aurophilic interactions b...

Despite the extensive use of aquatic insects to evaluate freshwater ecosystem health, little is known about the underlying factors that result in sensitivity differences between taxa. Organismal characteristics (respiratory strategy and body size) were used to explore the rates of [H]H2O and [ 14C]chlorpyrifos accumulation in aquatic insects. Ten aquatic insect taxa, including ephemeropteran, t...

In this work, hydrogen-bonding interactions between apigenin and water/ethanol were investigated from a theoretical perspective using quantum chemical calculations. Two conformations of apigenin molecule were considered in this work. The following results were found. (1) For apigenin monomer, the molecular structure is non-planar, and all of the hydrogen and oxygen atoms can be hydrogen-bonding...

Super- and sub-critical water treatments have been of interest as novel methods for protein hydrolysis. In the present study, we studied the effect of sub-critical water (Sub-H2O, 300℃, 80 bar) treatment as well as super-critical water (Super-H2O, 400℃, 280 bar) treatment on the physicochemical properties of porcine skin (PS), which has abundant collagen. Porcine skin was subjected to pre-therm...
