The development of new, efficient and selective synthetic methods is one of the major goals for future research in chemistry. An important and long-standing challenge in this field is to couple catalytic reactions with redox processes, which is expected to lead to interesting new reactions enabling (radical-type) transformations for substrates that are more difficult or impossible to activate o...

Using a conductive atomic force microscope (c-AFM) redox-writing technique, it is shown that it is possible to locally, and reversibly, pattern conducting, and nonconducting features on the surface of a low molecular weight aniline-based organic (semi)-conductor thin film using a commercial c-AFM. It is shown that application of a voltage between the tip and sample causes localized redox reacti...

Introduction The flavodoxins are a group of small proteins found in micro-organisms and eukaryotic algae that function to transfer electrons at low redox potential between other redox proteins in reactions such as nitrogen fixation and the photosynthetic reduction of NADP’ [ 1-41. They contain a single molecule of FMN bound strongly but non-covalently to the protein. The flavin is reduced in tw...

A nano-wired polyaniline/VS 2 network morphology mediated redox reactions of V and improved the overall conductivity to deliver a promising capacity long-term cyclability in energy storage devices (QSSCs ZIBs).

A Charge Transport (CT) mechanism has been proposed in several papers (e.g., Yavin et al. PNAS 102 3546 (2005)) to explain the localization of Base Excision Repair (BER) enzymes to lesions on DNA. The CT mechanism relies on redox reactions of iron-sulfur cofactors that modify the enzyme’s binding affinity. These redox reactions are mediated by the DNA strand and involve the exchange of electron...

Redox-inactive metal ions play pivotal roles in regulating the reactivities of high-valent metal-oxo species in a variety of enzymatic and chemical reactions. A mononuclear non-heme Mn(IV)-oxo complex bearing a pentadentate N5 ligand has been synthesized and used in the synthesis of a Mn(IV)-oxo complex binding scandium ions. The Mn(IV)-oxo complexes were characterized with various spectroscopi...

A three terminal molecular memory device was monitored with in situ Raman spectroscopy during bias-induced switching between two metastable states having different conductivity. The device structure is similar to that of a polythiophene field effect transistor, but ethylviologen perchlorate was added to provide a redox counter-reaction to accompany polythiophene redox reactions. The conductivit...

Most of the basic knowledge about radical reactions comes from radiation chemical studies in vitro. In view of the rapidly increasing knowledge on radical reaction in vivo, it is important to reconcile the fundamental physico-chemical reaction characteristics of radicals with the need to explain their alleged biological effects. Severe problems in the understanding of their in vivo action remai...
