Electrolytic Reduction of Quinones. II

Torque Ripple Reduction of Electrolytic Capacitor-less BLDC Motor Drive

Brushless DC motors called BLDC are used in many industrial and non-industrial applications today for reasons such as very high efficiency, easy control method and high reliability, and their use is increasingly used in mass production applications, especially home appliances. But these motors require the use of an electric drive, even in constant speed applications. Commercialization of these ...

Redesigning the QA binding site of Photosystem II allows reduction of exogenous quinones

Strategies to harness photosynthesis from living organisms to generate electrical power have long been considered, yet efficiency remains low. Here, we aimed to reroute photosynthetic electron flow in photosynthetic organisms without compromising their phototrophic properties. We show that 2,6-dimethyl-p-benzoquinone (DMBQ) can be used as an electron mediator to assess the efficiency of mutatio...

Reduction of Quinones by NADH Catalyzed by Organoiridium Complexes**

Correlation between cytotoxic activities and reduction potentials of heterocyclic quinones.

To search for possible anti-tumor agents or anti-tumor promoters among natural or synthetic products, we used cyclic voltammetry to determine the reduction-oxidation potentials of heterocyclic quinones in phosphate buffer at pH 7.2. We determined the growth inhibitory- and cytotoxic activities of 12 heterocyclic quinone anti-tumor agent candidates against a panel of 39 human cancer cell lines (...

Electrolytic Reduction of the Disulfide Bonds of Insulin.

The role disulfides play in the stabilization of the secondary and tertiary structure of proteins has been of interest to protein chemists for some time. Despite the considerable amount of recently acquired knowledge about the mechanism of protein biosynthesis, no information is available concerning either the exact chemical nature of the process leading to the joining of the sulfhydryl groups ...
