Blue crystals of [Cu(NN'dmen)(NO3)2] (where NN'dmen = N,N'-dimethyl-1,2-ethanediamine) were prepared and its structure was determined by single crystal X-ray crystallography. In this complex both the nitrates are mono-coordinated to the copper in cis positions. The IR spectra and ...

The complex bis-(N,N-dimethyl-1,2-ethanediamine) nickel(II) perchlorate undergoes a first-order thermochromic phase transition at ca. 476 K, changing its color from orange to red. The room temperature X-ray crystal structure determination showed that the nickel ion possesses a square-planar geom...

The atom-efficient and cost-effective rearrangement of oximes into primary amides is catalyzed by simple copper salts. The use of homogeneous Cu(OAc)2 (1–2 mol %) was found to be effective for this transformation at 80 °C. The reaction was successful with either conventional or microwave heati...

A novel collector 2-ethyl-2-hexenal oxime was synthesized from 2-ethyl-2-hexenal and hydroxylamine hydrochloride. The yield of oxime was 78.05% under the optimum experimental conditions. The oxime was characterized by elemental analysis, infrared spectrum, mass spectrum, 1H NMR and 13C NMR spect...

Oximes (R1R2C=NOH) are nitrogen-containing chemical constituents that are formed in species representing all kingdoms of life. In plants, oximes are positioned at important metabolic bifurcation points between general and specialized metabolism. The majority of plant oximes are amino acid-derive...

The microwave spectrum ofn-butyraldehyde oxime was observed in the frequency region 26.5–40 GHz. Four rotational conformers were found to exist in the gas phase; among these, two conformers belonged to the (E)-geometrical isomer and the other two to the (Z)-geometrical isomer. The microwave spe...

N-Nitrosodialkylamines are known to be potent indirect-acting mutagens/carcinogens, which are activated by cytochrome P450. The reaction product of N-nitroso-N-methylbutylamine (NMB) with modified Fenton’s reagent supplemented with copper salt (Fe2+–Cu2+–H2O2) was reported to be mutagenic in ...

The excess volume of (3-methoxypropionitrile + water) was studied precisely, at several temperatures in the immediate vicinity of the upper critical solution temperature, using a dilution dilatometer. The experimental results, covering reduced temperatures from ϵ = −0.042 to ϵ = +0.0065 where ϵ ...

Propionitrile (PPN) or 3-methoxypropionitrile (MPN) is mixed with acetonitrile (ACN) to prepare ACN/PPN and ACN/MPN co-solvents and used to fabricate polymer gel electrolytes (PGEs) of dye-sensitized solar cells (DSSCs), aiming at improving the stability of gel-state DSSCs. Co-solvents with vari...

(Liquid + liquid) equilibria are presented for (hexadecane + tetralin + 3-methoxypropionitrile) at the two temperatures 298.15 K and 348.15 K.

Ternary (liquid + liquid) equilibria are reported for (n-decane + n-butylbenzene + 3-methoxypropionitrile) at the three temperatures 298.15, 323.15, and 348.15 K. A new design of an equilibrium cell is presented.

The microwave spectrum of 3-methoxypropionitrile, CH3OCH2CH2CN, has been investigated in the region 16 to 40 GHz. The spectrum reveals the presence of only one rotational isomer, the fully-trans form (with C8 symmetry). For the ground vibrational state the rotational constants are A = 17 821 ± ...

The kinetics of the thiocyanate substitution of the solar cell sensitizer [Ru(Hdcbpy)2(NCS)2]2−, 2(n-C4H9)4N+ (H2dcbpy=L=2,2′-bipyridine-4,4′-dicarboxylic acid), known as N719, by acetonitrile, 3-methoxypropionitrile, and 4-tert-butylpyridine (4-TBP) have been determined in both homogenous sol...

The dye-sensitized solar cell dye Z-907, [RuLL′(NCS)2] may loose a thiocyanate ligand at elevated temperatures (80–100 °C) by ligand exchange with the solar cell additive 4-tert-butylpyridine (4-TBP) or the electrolyte solvent 3-methoxypropionitrile (3-MPN). The mechanism in homogeneous solut...

Cu2O is an attractive material in terms of semiconducting properties and is considered a leading candidate in all-oxide photovoltaics. Electrochemical analysis of Cu2O, including Mott-Schottky (MS) and impedance spectroscopy (IS), provides a wealth of data on charge carriers, Fermi level and int...

Organic sulfur compounds are ubiquitous in natural oil and gas fields and moderate-low temperature sulfide ore deposits. Previous studies have shown that organic sulfur compounds are important in enhancing the rates of thermochemical sulfate reduction (TSR) reactions, but the details of these re...

We mechanically fabricated Fe, Co, and Ni nanowires showing conductance quantization under electrochemical potential control. The effects of 2-butyne-1,4-diol and saccharin on the stability of the nanowires were investigated by measuring the conductance and the stretched length of the nanowires....

Hydrogenation of 2-butyne-1,4-diol to 2-butene-1,4-diol (B2D) and butane-1,4-diol (B1D) using Pt catalysts doped with alkali metals was studied.
