iv Overall, the results presented in this thesis contribute to the solution of the “electronic coupling problem”, arising when interfacing biomolecules with electronics and limiting the performance of bioelectrocatalytic systems in practical applications. The developed methods to facilitate electron transfer will hopefully promote future biosensing devices and biofuel cells. I believe that the ...

Transitions of one or two electrons in C-He collisions are studied within the semiclassical close-coupling description of atomic collisions, at impact energies of 1–35 keV/u. Angle-integrated cross sections are determined for single-transfer, double-transfer, and transfer-excitation channels. For single capture to 3p states and for two final states in the two-electron transfer channel, angle-di...

magnetite (fe3o4) nanoparticles have been successfully prepared by a novel one-step and surfactant-free approach utilizing ferrous ion, as a single iron source. in this manner, the reaction occurs between two aqueous solutions via the spontaneous transfer of ammonia gas from one to another in room temperature. no ferric source or oxidizing specie, oxidation controlling and capping agents are ne...

The reaction mechanisms by which antioxidants can exert their activity are: hydrogen atom transfer (HAT), proton coupled electron transfer (PCET), sequential proton loss electron transfer (SPLET), single electron transfer proton transfer (SET-PT), radical adduct formation, and sequential proton loss hydrogen atom transfer. The antioxidative activity of different compounds (flavones, flavonols, ...

With NADPH as the electron donor, rat liver NADPH cytochrome P-450 reductase (NADPH:ferricytochrome oxidoreductase, EC 1.6.2.4) catalyzes the single-electron reduction of several quinone antibiotics to a semiquinone or free radical state. The benzanthraquinones adriamycin, daunorubicin, carminomycin, 7-O-methylnogalarol, and aclacinomycin A and the N-heterocyclic quinones streptonigrin and mito...

The effects of local structural disorder on excess electron transfer (EET) in DNA were investigated by evaluating photoinduced electron transfer in phenothiazine (PTZ)-modified oligodeoxynucleotides bearing single-base mismatches. Unexpectedly, more efficient electron transfer was observed for the mismatched duplexes than for the complementary DNA, suggesting that distraction of hydrogen bond i...

Single-electron transistors SETs are often discussed as elements. A single-electron transistor consists of a small conducting island coupled to source and.Single-electron transistor SET is a key element in our research field where.
