The activation thermodynamic parameters are calculated using Coats- Redfern and Horowitz-Metzger methods. Antimicrobial activity of the compounds was evaluated against some bacteria and fungi species. The activity data show that most metal complexes have antibacterial activity than that of the parent HOfl...
In acetonitrile-based electrolytes, all compounds show a stepwise two electron chemically and electrochemically reversible reduction of the viologen moieties. In the case of the bis-viologen, peak potential difference data indicate a weak difference in the formal potentials of the two non-conjugated ...
Plants play an ever-increasing role not only for providing safe and healthy food for a growing world population but also for new biotechnologies including phytoremediation of areas contaminated by toxic metals, phytofortification used in functional foods
Volumetric properties of macromolecules and low-molecular compounds are necessary auxiliary means for the determination of molar masses from solution-scatt... H Durchschlag,P Zipper - 《Journal of Applied Crystallography》 被引量: 71发表: 1997年 Synthesis and characterization of side-chain liquid cryst...
The preparation of 1:2 and 1:1 mercury(II) chloride and bromide complexes with 2- and 4- cyanoanilines is described. These compounds are freely soluble in ethanol in which they behave as non-electrolytes. Molecular weight measurements in molten camphor indicate the 1:1 complexes as monomeric...
The solids are monomers and behave as non-electrolytes in acetonitrile solution. The molecular structures of the complexes were studied on the basis of 1H NMR and IR spectra. The most probable structure is that of a trigcnal bipyramid with the halogen atoms in equatorial positions and the two...
The corrosion inhibition performances of the compounds were investigated on mild steel (MS) in 0.5 M H2SO4 medium using electrochemical measurements, surface analysis, quantum chemical calculations and molecular dynamic simulations (MDS). Potentiodynamic polarization (PDP) measurements revealed that the...
Plant sterols are compounds that have been shown to lower LDL-cholesterol. Açaí is actually quite high in calories due to the presence of the fatty acids and is a complete meal containing fats, proteins and a small amount of carbohydrates (3). Açaí is also a good source of potassium...
Tears are non-invasively accessible, with samples most often collected either with glass capillaries or with Schirmer strips (sterile filter paper strips) [106]. Tears contain proteins, peptides, lipids, small molecular metabolites and electrolytes. In humans, their composition has been monitored both...
Diazepam (pKa 3.4) and benzocaine (pKa 2.8) are both weakly basic compounds. At neutral pH, these compounds should be essentially completely unionized. For most of the cosolvent-water mixtures used, these two solutes could be treated as nonelectrolytes. However, the more dilute concentrations of...
