Structural and electrical characterisation of silicon and other semiconducting nanoparticle networks for use in sensor and photovoltaic applications
… and reduced sulphur species, generated through incomplete oxidation of sulphidic ores, are primarily responsible for thiocyanate formation. In addition, thiocyanate generated during these processes has been identified to mobilise both base metals and precious metals, forming highly stable and …

Enzymatic fuel cells via synthetic pathway biotransformation
… emerging enzymatic fuel cell technologies are incomplete oxidation of most fuels, limited power output, and short lifetime of the cell. Synthetic pathway biotransformation is a technology of assembling a number of enzymes coenzymes for producing low-value biocommodities. In this work, it was …

The redox and iron-sulfide geochemistry of Salt Pond and the thermodynamic constraints on native magnetotactic bacteria
… and measured voltammetric data verify fields of incomplete oxidation resulting in the production of elemental sulfur, thiosulfate and polysulfides. Calculations of the Gibbs free energy in the Salt Pond chemocline for potential microbial redox reaction involving iron and sulfur species indicate …

Local Structures of Niobium-Containing Cation-Disordered Rocksalt Materials: Cobalt-Free Cathodes for Lithium-Ion Batteries
… however the spectra are complicated by the incomplete oxidation of Ni to Ni4+, meaning any possible O redox signal is obscured by unpaired spin density from Ni.

The Development of Genetic Tools for Protein Characterization and Genetic Engineering in the Acetic Acid Bacterium Gluconobacter Oxydans
… oxydans is well known for its ability to incompletely oxidize carbon substrates under normal conditions. The incomplete oxidations are carried out by membrane-bound dehydrogenases that channel electrons directly into the electron transport chain. Many of these oxidative products are regio- …

Electrochemical and spectroscopic interfacial investigations of small organic molecule electrooxidation on platinum electrodes
… for fuel cells, the intermediates of the oxidation of formic acid and ethanol to CO2 on platinum electrodes have been examined. The adsorbed carbon monoxide intermediate continues to be the cause for a decrease in efficiency and activity for platinum electrodes and is the leading surface …

Oxidative Treatment of Emerging Micropollutants and Viral Pathogens by Potassium Permanganate and Ferrate: Kinetics and Mechanisms
… a sufficient barrier to pathogens. Chemical oxidation processes involving permanganate [MnO4-, Mn(VII)] and ferrate [FeO42-, Fe(VI)] salts are promising technologies for treatment of many PhACs. Permanganate is already widely used in water treatment facilities (e.g., for treatment of taste …

Optimisation of a linear flow channel reactor for semi-passive, simultaneous biological sulphate reduction and partial sulphide oxidation
… which integrates BSR, and concomitant partial oxidation, by sulphur oxidising bacteria (SOB), of the sulphide produced to elemental sulphur. This is generated as a floating sulphur biofilm (FSB). These processes occur simultaneously within a linear flow channel reactor (LFCR), facilitating both …

Linking microbial community dynamics and performance of a biological sulphate reducing system using a mixed volatile fatty acid stream as electron donor
… a feed sulphate concentration of 1.0 g l-1 , the oxidation of acetate, propionate and butyrate and concomitant sulphate reduction were observed across the dilution rates of 0.0083 to 0.083 h -1 . The stoichiometry of BSR utilising propionate and butyrate as carbon and electron donor suggested that …
