The role of a redox-active non-innocent ligand in additive-free C-C Glaser-Hay and Suzuki coupling reactions by an -aminophenol palladium(ii) complex.

A novel mononuclear palladium complex with 2-(3,5-di--butyl-2-hydroxyphenyl amino) benzonitrile as a non-innocent ligand (abbreviated as PdL ) was synthesized, and characterized by IR, UV-Vis, H and C NMR spectroscopies and elemental analysis. The crystal structure clearly showed that the metal center was in a square planar environment. The bond lengths obtained from X-ray structure analysis revealed that both ligands are in the -iminobenzosemiquinone radical form.

Dynamics of quantum turbulence of different spectra.

Turbulence in a superfluid in the zero-temperature limit consists of a dynamic tangle of quantized vortex filaments. Different types of turbulence are possible depending on the level of correlations in the orientation of vortex lines. We provide an overview of turbulence in superfluid (4)He with a particular focus on recent experiments probing the decay of turbulence in the zero-temperature regime below 0.

Biohydrogen production from CO-rich syngas via a locally isolated Rhodopseudomonas palustris PT.

Biohydrogen production through water–gas shift (WGS) reaction by a biocatalyst was conducted in batch fermentation. The isolated photosynthetic bacterium Rhodopseudomonas palustris PT was able to utilize carbon monoxide and simultaneously produce hydrogen. Light exposure was provided as an indispensable requirement for the first stage of bacterial growth, but throughout the hydrogen production stage, the energy requirement was met through the WGS reaction.

Excimers He2* as tracers of quantum turbulence in 4He in the t = 0 limit.

We have studied the interaction of metastable 4He2* excimer molecules with quantized vortices in superfluid 4He in the zero temperature limit. The vortices were generated by either rotation or ion injection. The trapping diameter of the molecules on quantized vortices was found to be 96±6  nm at a pressure of 0.
