Ligand steric effects were assessed via cone angles and surface coverage. Weak C─H⋯π and C─H⋯X interactions stabilized the crystal packing, while [NiCl₂(PBz₃)₂] and [NiBr₂(PBz₃)₂] showed rare agostic and anagostic competition. Abstract Full text PDF References ...
A successful caustic regeneration of fire-resistant fluid-fouled strong base anion resin using citric acid as an eco-friendly and cost-effective alternative has been achieved, with a promising ion exchange capacity recovery of up to 55 %. The reasons for the high efficiency of citric acid were...
To further test the hypothesis that the downstream target of Cygb2-dependent NO signaling is indeed sGC, we treated embryos with the specific small molecule sGC activator BAY 582667 (cinaciguat), able to activate sGC, regardless of the presence of its ligand NO. The percentage of left-sided ...
The N–S bond in the latter complex is, however, weak and can undergo both heterolytic and homolytic splitting. The former process makes the synthesis reaction reversible, whereas the latter is responsible for the spontaneous redox decomposition: FeCN5NOSRn2→FeiCN5NO3RSn1. The rate of the ...
This activation is severely impaired if the CD4-bindingsite on the agonist ligand is ablated, but the same mutation on anendogenous ligand has no effect. These data correlate well withanalyses of lipid bilayers and cells presenting these ligands, andindicate that the basic unit of helper T ...
(D) PX432 lead to a strong expression in four nuclei at the IJ (black arrow), in the optic lobe anlagen (white arrow) and in many nuclei of the VNC. (E) PZ442 is expressed in a fibrous structure at the IJ. A weak signal is detectable in the optic lobe anlagen. (F) PX425 ...
Fenton reaction4is frequently used, because this has been accepted to rapidly generate OH radicals decomposing organic molecules5,6,7. The Fenton reaction uses H2O2solution with catalytic ferrous (Fe2+) or other ions. This is a widely-used durability test for proton exchange membranes (PEMs) in...
This favorable electrostatic interaction stabilizes the bound O 2 by a factor of 1000, and the net result is a 100-fold increase in overall affinity compared to model hemes or mutants with an apolar residue at position 64. Electrostatic interaction between FeCO and His64 is very weak, ...
Epidemiological studies have provided weak evidence of the link between hair dye use and carcinogenicity3,5,41,42,43. 4-Cl-OPD is a commonly used hair dye precursor in permanent formulations; it is linked to increased ROS production in vitro and in vivo, protein aggregation, genotoxicity, and...
Go dry to get wet: Solventless synthesis of water-soluble ZnO nanocrystals is achieved by a mild mechanochemical pathway based on rational design of oxo-zinc precursors. The applied bottom-up methodology allows for synthesis of organic ligand-coated nanocrystals as well as their host–guest surface...
