Structural insights into microbial one-carbon metabolic enzymes: Ni–Fe–S-dependent carbon monoxide dehydrogenases and acetyl-CoA synthases
… their catalysis is coupled through an internal gas channel between the CODH and ACS active sites. These carbon-fixing enzymes are thought to be among the oldest on earth, dating back to the last universal common ancestor based on strong conservation of these enzymes between bacterial and …

Hydrogen Gas Production and Effects During Remediation Using Nano-scale Zero-valent Iron
… of the potential effects of hydrogen gas (H2) exsolution during nanoscale zero-valent iron (nZVI) groundwater remediation applications. An improved understanding of gas exsolution and its effects can be applied to remediation technologies that produce gas in excess of solubility …

Three-dimensional mathematical model of a high temperature polymer electrolyte membrane fuel cell
… which accounts for the convective and diffusive gas flow in the gas channel, multi-component diffusion in the porous backing layer, electrochemical reactions in the catalyst layers, as well as flow of charge and heat through the solid media. The governing equations which mathematically describe …

Development and validation of a computational model for a proton exchange membrane fuel cell
… model, the solution domain includes a gas channel, gas diffusion layer, and catalyst layer for both the anode and cathode sides of the cell as well as the solid polymer membrane. For the three-dimensional model the current collectors are also modeled on both the anode and cathode sides …

Solid Oxide Fuel Cell Modeling at the Cell Scale - Focusing on Species, Heat, Charge and Momentum Transport as well as the Reaction Kinetics and Effects
… there are no direct emissions of greenhouse gases. Various improvements are made during the recent years, however the technology is still in the early phases of commercialisation. Fully coupled computational fluid dynamics (CFD) approaches based on the finite element method (with the software …

Physics and application of an atmospheric pressure plasma jet
… remote from the discharge area and the low gas temperature. In this study the electrically driven plasma source is a dielectric barrier discharge of a structure similar to that designed by Teschke et al in 2005, which has been studied recently by many research groups in different …
