Ion-pairing and optical activity of diastereomeric zinc(II) 1, 10-phenanthroline, S-valinate systems
(1983)
A series of S-valinatobis(1, 10-phenanthroline)zinc salts in methanolic solution have been prepared and their conductivities and ORD spectra measured. A positive linear correlation of optical rotation with conductance was ...
Role of superoxide anions in the redox changes affecting the physiologically occurring Cu(I)-glutathione complex
(2011)
The physiologically occurring copper-glutathione complex, [Cu(I)-[GSH]2], has the ability to react continually with oxygen, generating superoxide anions (O 2 -). We addressed here the effects that superoxide removal has ...
Binding of electrolytes to poly(ethylene oxide) in methanol
(1986)
The binding of potassium and sodium salts (thiocyanate and iodide as anions) to polyethylene
oxide) in methanol solutions has been studied. The study was performed by the use of fluorescence techniques
and ultrafiltration ...
