DEMONSTRATION OF HETEROARYLMETHANE OXIDATION IN A BENZIMIDAZOLE DERIVATIVE WITH THE USE OF UV SPECTROPHOTOMETRY AND X-RAY DIFFRACTION

Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2012
In this work, we present the synthesis of a copper complex of 1-benzyl-2-[(5-methyl-isoxazol-3-yl)methyl]-benzimidazole, by using simultaneously UV spectrophotometry and X-ray diffraction. It has been possible for us to highlight an original oxidation of

Antagonistic Role of Aqueous Complexation in the Solvent Extraction and Separation of Rare Earth Ions

, 2021
During solvent extraction of rare earth ions, an aqueous electrolyte solution is placed in contact with an immiscible organic solution of extractants to enable extractant-facilitated transport of ions into the organic solvent.

Straightforward synthesis of gold nanoparticles by adding water to an engineered small dendrimer

Beilstein Journal of Nanotechnology, 2020
A small water-soluble phosphorus-containing dendrimer was engineered for the complexation of gold(I) and for its reduction under mild conditions. Gold nanoparticles were obtained as colloidal suspensions simply and only when the powdered form of this ...

Proton and cadmium adsorption by the archaeon Thermococcus zilligii: Generalising the contrast between thermophiles and mesophiles as sorbents

, 2010
Adsorption by microorganisms can play a significant role in the fate and transport of metals in natural systems. Surface complexation models (SCMs) have been applied extensively to describe metal adsorption by mesophilic bacteria, and several recent ...

Therapeutic Apheresis for Intravenous Methylprednisolone‐Refractory Neuromyelitis Optica Spectrum Disorder: Clinical and Radiological Outcomes in a Single‐Center Case Series

Therapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing autoimmune disease of the central nervous system. High‐dose intravenous methylprednisolone (IVMP) is the standard first‐line therapy for acute attacks, although some patients remain refractory.

Complexation mechanism of dextrin with metal hydroxides [PDF]

, 1998
The complexation of dextrin with metal hydroxides was studied quantitatively by FT-IR and UV–visible reflectance techniques. Though three hydroxyl groups are present in dextrin molecule, complexation involving only two hydroxyl groups situated at the ...
