Effect of excess free energy of solvents on the oxidation of methionine by quinolinium fluorochromate: A kinetic study [PDF]

open access: yesJournal of the Serbian Chemical Society, 2008
The oxidation of methionine by quinolinium fluorochromate (QFC) was studied in the presence of chloroacetic acid, in water/organic solvent mixtures of varying excess molar free energy function.

Solvent Effects on Electrophilicity

open access: yesJournal of the American Chemical Society, 2001
Continuum solvent effect on the electrophilicity index recently proposed by Parr and co-workers (Parr, R. G.; von Szentpaly, L.; Liu, S. J. Am. Chem. Soc. 1999, 121, 1922) is discussed in detail. Solvent effect is introduced using the self-consistent isodensity polarized continuum model (SCI-PCM).

Solute Effects on the Helix-Coil Transition [PDF]

open access: yes, 2002
We discuss the effects of the solvent composition on the helix-coil transition of a polypeptide chain. We use a simple model to demonstrate that improving the hydrogen-bonding ability of the solvent can make the transition less cooperative, without ...

Solvent dependent in situ growth of NixSy supported on nickel foam as electrocatalysts for oxygen evolution reaction

open access: yesInternational Journal of Electrochemical Science, 2016
In situ growth of NixSy on nickel foam (NixSy/NF) has been investigated by hydrothermal or solvothermal process in water, ethanol and their mixture. XRD shows that the obtained NixSy is consisted of Ni3S2 and NiS in the three solvents.

Novel Approach to the Preparation of Lead Chalcogenide Colloidal Quantum Dots and Properties Thereof

open access: yesMaterials Proceedings, 2023
In this work, we report the study of resizing of lead chalcogenide quantum dots, both PbS and PbSe, in the presence of the oleylamine/oleic acid mixture. We demonstrate that the resizing of lead chalcogenide nanocrystals could be performed in aprotic non-

Solvent-dependent synthesis and mono-hydrolysis of di-Schiff base of (+/-)trans-1,2-cyclohexanediamine and 2-pyridinecarboxaldehyde in Cu(II), Co(II) and Zn(II) complexes [PDF]

open access: yesJournal of the Serbian Chemical Society, 2012
The Schiff base ligand trans-N,N′-bis[2-pyridinecarboxylidene] cyclohexane-1,2-diamine (L) was synthesized. This ligand when stirred with 1 equiv of MCl2.xH2O (M = Cu, Co, Zn) in ethanol, undergoes partial hydrolysis of the imino bond and the result ...
