Uranium atoms activate methane upon ultraviolet excitation to form the methyl uranium hydride CH3-UH, which undergoes alpha-H transfer to produce uranium methylidene dihydride, CH2UH2. This rearrangement most likely occurs on an excited-quintet potential-energy surface and is followed by relaxation in the argon matrix. These simple U + CH4 reaction products are identified through isotopic substitu

Heme oxygenase is an enzyme that degrades heme, thereby recycling iron in most organisms, including humans. Pervious density functional theory (DFT) calculations have suggested that iron(III) hydroxyheme, an intermediate generated in the first step of heme degradation by heme oxygenase, is converted to iron(III) superoxo oxophlorin in the presence of dioxygen. In this article, we have studied the

The Reactions with Relativistic Radioactive Beams (R3B) experiment at FAIR focuses on kinematically complete measurements, primarily involving atomic nuclei far from stability, using relativistic beams. The Facility for Anti-proton and Ion Research (FAIR), which R3B is part of, is a new convention bound international accelerator facility where Sweden is a share holder and a founder member. The R3B

Popular Abstract in English Modern society is still largely based on fossil resources. However, there are growing concerns about the security and cost of these resources, as well as climate change resulting from the combustion of fossil fuels. Biofuels represent renewable fuels with the potential to mitigate the adverse effects of fossil fuels, providing a more sustainable alternative. The transpBioethanol from sugarcane is a sustainable alternative to fossil fuels, and the increasing demand for fuel ethanol has prompted studies on the use of the lignocellulosic residues of sugarcane, namely bagasse and leaves, as new feedstock. This thesis describes various process designs and the economic feasibility of producing second generation (2G) ethanol from bagasse and leaves via the enzymatic r

Mitigating degradation is essential for extending the lifetime of solid oxide electrochemical cells (SOCs). The conditions leading to degradation, e.g. overpotentials, gas partial pressures, thermal gradients are hard, if not impossible, to retrieve experimentally. Thus, to deconvolute the response from cell testing, modeling can be applied to understand the degradation phenomena in greater detail

A Fuel cell is a highly efficient device for converting chemical energy in fuels to electrical energy and the electrical efficiency is strongly affected by the porosity in electrodes due to its close couplings with mass transfer and active sites for the electrochemical reactions, which will also cause changes in distribution of thermal stresses inside the electrodes. A three-dimensional computatio

Combustion of NH3 with H2 addition can improve the combustion stability. In this study, the laminar burning velocities (LBVs) of NH3/H2/O2/CO2 mixtures were determined under atmospheric pressure and an initial temperature of 303 K by the heat flux method, spanning CO2 fractions of 0.50-0.75, H2 fractions of 0.20-0.70, and equivalence ratios of 0.6-1.5. Evaluations of three kinetic models (modified

Cell immobilization and co-culture techniques have gained attention due to its potential to obtain high volumetric hydrogen productivities (QH2). Chitosan retained biomass in the fermentation of co-cultures of Caldicellulosiruptor saccharolyticus and C. owensensis efficiently, up to a maximum dilution rate (D) of 0.9 h−1. Without chitosan, wash out of the co-culture occurred earlier, accompanied w

A four-dimensional intermolecular potential-energy surface has been calculated for the HCN-HCl complex, with the use of the coupled cluster method with single and double excitations and noniterative inclusion of triples. Data for more than 13 000 geometries were represented by an angular expansion in terms of coupled spherical harmonics; the dependence of the expansion coefficients on the intermol
