EPR Methods for Biological Cu(II): L-Band CW and NARS [PDF]

, 2015
: Copper has many roles in biology that involve the change of coordination sphere and/or oxidation state of the copper ion. Consequently, the study of copper in heterogeneous environments is an important area in biophysics. EPR is a primary technique for

Characterization by epr spectroscopy of the chiral catalysts bis(oxazoline)-Cu supported in laponites

Boletín de la Sociedad Española de Cerámica y Vidrio, 2000
An Electron Paramagnetic Resonance study of a chiral Bis(oxazoline)-Cu(II) supported in laponite (synthetic hectorite) is presented. It is concluded that the complex is incorporated into the interllamellar space of the clay giving out isolated Cu(II ...

Correlation between UV-VIS spectra and the structure of Cu(II) complexes with hydrogenated dextran in alkaline solutions [PDF]

Hemijska Industrija, 2005
UV-VIS spectrophotometric investigations of Cu(II) complexes with hydroge-nated dextran showed that the complexation of Cu(II)-ions began at pH > 7. The formation of Cu(II) complexes with dextran monomer units was observed at pH 7-12.

UV-driven trace Cu(II)/peroxymonosulfate for efficient degradation of phosphonate: Mechanism and broad pH adaptability

Chemical Engineering Journal Advances
Organic phosphonates detected frequently in water bodies pose severely environmental risks, and the cleavage of their C-P bonds to converse orthophosphate (PO43-) serves as a prerequisite step for achieving deep phosphorus elimination.

Interplay between lattice, orbital, and magnetic degrees of freedom in the chain-polymer Cu(II) breathing crystals [PDF]

, 2013
The chain-polymer Cu(II) breathing crystals C21H19CuF12N4O6 were studied using the x-ray diffraction and ab initio band structure calculations. We show that the crystal structure modification at T=146 K, associated with the spin crossover transition ...

Redox Activity of the Mini-αA-crystallin–Cu(II) Complex and Its Biological Relevance

International Journal of Electrochemical Science, 2015
Cu(II) has been known to be a redox-active metal whose complexes with proteins/peptides have been linked to oxidative stress in many diseases. Oxidative stress and Cu(II) are also known to induce the expression of the small heat shock proteins α ...
