The thesis is focused on the study of antioxidant activity of chitosan and its obtaining from chitin by different methods. The use of chitosan and chitosan functionalized with dihydroxyfumaric acid in azithromycin nitrosation ...

Cu and Ni complexes of chitosan/poly(vinyl amine) (CS/PVAm) composites were prepared. The metal-CS/PVAm complexes were characterized by FT-IR spectroscopy, SEM-EDX, X-ray diffraction (XRD), and magnetic moment determination. ...
