Reduction of Ag+ on polyacrylate chains in aqueous solution
Article Abstract:
Research was conducted to examine the reduction of Ag+ on polyacrylate chains in aqueous solution. The hydrated electron or hydrogen acted as the reducing agent. It was observed that complexes of small silver clusters with the polyelectrolyte are formed in the early stages of reduction with the color of the solutions varying from rose to green or blue based on the size of the complexed silver clusters. Results indicate that colored clusters react with cyanide and ammonia to form large silver particles through the intermediate stage of the magic cluster.

First determination of the standard potential for the dissociative reduction of the antimalarial agent artemisinin
Article Abstract:
Cyclic voltammetry and electromechanical methods were used to study the reduction of the antimalarial agent Artemisinin (ART) in N,N-dimethylformamide (DMF). The standard potential of the dissociative reduction of ART is found to be -0.89 V versus SCE in DMF, which is ca. 0.8 V more positive than the irreversible direct reduction resulting from cyclic voltammetric measurements. Moreover, the value of the dissociative reduction of ART can be used to estimate the O-O bond dissociation energy.

Chaos during the reduction of iodate in alkaline solution: geometrical effect of the electrode
Article Abstract:
The geometrical effects of the electrode on the oscillatory behavior of iodate in an alkaline solution during reduction were investigated. Experimental results showed that the geometrical factors strongly influence the oscillatory behavior of iodate when the iodate concentration is smaller and chaos appears on the electrodes with smaller size or smoother surface. In contrast, the effect of geometrical factors on iodate is negligible when the iodate concentration is higher.
