We for the first time report a facile, wet-chemical strategy for the high-yield (approximately 100%) synthesis of ultralong Pt-on-Pd bimetallic nanowires (NWs) with the cores being Pd NWs and the shells being made of dendritic Pt, which exhibit high surface area and enhanced electrocatalytic activity towards methanol oxidation reaction.

We report a simple and low-cost strategy that allows the sequential and site-specific assembly of a dehydrogenase-based multi-enzyme cascade for methanol oxidation on the yeast surface using the high-affinity interactions between three orthogonal cohesin-dockerin pairs. The multi-enzyme cascade showed 5 times higher NADH production rate than the non-complexed enzyme mixture, a result of efficie...

In order to demonstrate the activation effects of a Pt electrode by laser pulse irradiation, the electro-oxidation of glucose was tested at an activated Pt electrode by cyclic voltammetry. A fixed potential was applied to the electrode, and then the electrode was irradiated with laser pulses from a Nd:YAG laser at 20 Hz for 20 s. Activation by the laser pulse irradiation gave two remarkable eff...

Abstrsct—An enzyme system capable of oxidizing both methanol and ethanol in the 0 presence of DPN was purified almost nine ty-fold from the liver of the rhesus monkey. Data for theK, values for the two alcohols and DPN and for the R values in the presence of some inhibitors are presented. The enzyme ap rs to be identical to liver alcohol hydrogenase AD 1. Eihlili competitively inhibited the oxi...

Two structural forms of a ternary alloy PtRuIr/C catalyst, one amorphous and one highly crystalline, were synthesized and compared to determine the effect of their respective structures on their activity and stability as anodic catalysts in methanol oxidation. Characterization techniques included TEM, XRD, and EDX. Electrochemical analysis using a glassy carbon disk electrode for cyclic voltamm...

The complete electro-oxidation of glycerol to CO2 is performed through an oxidation cascade using a hybrid catalytic system combining a recombinant enzyme, oxalate decarboxylase from Bacillus subtilis, and an organic oxidation catalyst, 4-amino-TEMPO. This system is capable of electrochemically oxidizing glycerol at a carbon electrode collecting all 14 electrons per molecule.

The aim of this research was to make the first depth profiles of the microbial assimilation of methanol carbon and its oxidation to carbon dioxide and use as an energy source from the microlayer to 1000 m. Some of the highest reported methanol oxidation rate constants of 0.5– 0.6 d−1 were occasionally found in the microlayer and immediately underlying waters (10 cm depth), albeit these samples ...
