Bio-butanol as fuel for direct alcohol fuel cells - investigation of Sn modified Pt catalyst for butanol electro-oxidation [PDF]
, 2016 Direct alcohol fuel cells (DAFCs) mostly use low molecular weight alcohols such as methanol and ethanol as fuels. However, short-chain alcohol molecules have a relative high membrane crossover rate in DAFCs and a low energy density.

Effect of Environmental pH on Mineralization of Anaerobic Iron-Oxidizing Bacteria
Frontiers in Microbiology, 2022 Freshwater lakes are often polluted with various heavy metals in the Anthropocene. The iron-oxidizing microorganisms and their mineralized products can coprecipitate with many heavy metals, including Al, Zn, Cu, Cd, and Cr.

Deracemization By Simultaneous Bio‐oxidative Kinetic Resolution and Stereoinversion [PDF]
Angewandte Chemie International Edition, 2014 AbstractDeracemization, that is, the transformation of a racemate into a single product enantiomer with theoretically 100 % conversion and 100 % ee, is an appealing but also challenging option for asymmetric synthesis. Herein a novel chemo‐enzymatic deracemization concept by a cascade is described: the pathway involves two enantioselective oxidation ...

Use and misuse of FTIR spectroscopy for studying the bio-oxidation of plastics [PDF]
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2021 Due to massive production, inefficient waste collection, and long lives, plastics have become a source of persistent pollution. Biodegradation is explored as an environmentally friendly remediation method for removing plastics from the environment. Microbial and animal biodegradation methods have been reported in the literature for various plastics ...

One Novel two-step Bio-Oxidation Pretreatment of Arsenic-Containing Gold-Bearing Concentrate
International Journal of Electrochemical Science, 2018 A novel process was developed to markedly increase gold cyanidation performance from an arsenic-containing gold-bearing concentrate. Before cyanidation, a two-step bio-oxidation pretreatment was employed to decrease the arsenic content in the residue and

Bio-oxidation of H2S by Sulfolobus metallicus
Biotechnology Letters, 2011 Sulfolobus metallicus is a hyperthermophilic and chemolithoautotrophic archaeon that uses elemental sulfur as an energy source. Its ability to oxidize H(2)S was measured either in the presence or absence of elemental sulphur, showing its ability for using both as an energy source. A biotrickling filter was set up and a biofilm of S.

Real-time quantitative analysis of volatile products generated during solid-state polypropylene thermal oxidation [PDF]
, 2013 Analysis of volatile organic compounds (VOCs) during PP thermal oxidation under three oxygen partial pressures (0%, 21% and 100% of atmospheric pressure) at 140 C was performed by proton transfer reaction coupled with Fourier transform ion cyclotron ...

Transactions of Nonferrous Metals Society of China, 2008 Abstract Oxidation of arsenopyrite with Acidithiobacillus ferrooxidans was studied. The electrochemical results show that arsenopyrite is firstly oxidized to As 2 S 2 at the potential of 0.2−0.3 V (vs SHE) and As 2 S 2 covers the electrode and retards the process continuously.
