Dynamic site‐interconversion reduces the induction period of methanol‐to‐olefin conversion
AIChE Journal, EarlyView.Abstract Reaction–diffusion coupling across the catalyst pore, grain, pellet, and reactor bed has been studied using a particle‐resolved transient microkinetic model applied to temperature‐programmed desorption and step‐response studies of methanol and dimethyl ether conversion over ZSM‐5 catalysts, respectively.

Neuroimaging Biomarkers for Friedreich Ataxia: A Cross‐Sectional Analysis of the TRACK‐FA Study
Annals of Neurology, EarlyView.Objective We aimed to quantify differences in the brain and spinal cord between Friedreich ataxia and controls, stratified by age and disease stage, including for the first time in young children. Methods TRACK‐FA is the largest prospective, longitudinal, multi‐modal neuroimaging study in Friedreich ataxia to date.

Reactions of R3PNNPR3 Species with Boranes: Classical Adducts, FLPs, and Radical Cations
Angewandte Chemie, EarlyView.Depending on the substituents, bis‐phosphazine species R3PNNPR3 (R = Ph 1, Cy 2) react with boranes to give Lewis acid–base adducts, generate frustrated Lewis pairs (FLP), or effect single electron transfer affording a frustrated radical pair (FRP). The B(C6F5)3 and BF3 adducts of 1 and the radical salts [R3PNNPR3]•+[BF4] (R = Cy 5b Cy 6) were obtained

Angewandte Chemie, EarlyView.The structure and biosynthetic origin of the enigmatic “yellow affinity substance” (YAS) from the anaerobe thermophile Clostridium thermocellum (now: Acetivibrio thermocellus) were elucidated. YAS is a complex of unusual antibacterial arylpolyene alkaloids (celluxanthenes) that are produced by various cellulolytic anaerobes.

Angewandte Chemie, EarlyView.Ein biomimetisches Lipiddoppelschichtmembran‐System ermöglicht einen lichtinduzierten Elektronentransfer durch die Membran unter sowohl aeroben (sauerstoffreichen) als auch anaeroben (sauerstoffarmen) Bedingungen. Der Elektronentransfer wird durch einen organischen Chromophor vermittelt – ein Molekül, das symmetrisch aufgebaut und leicht zu ...

Demonstrating the Use of a Fungal Synthesized Quinone in a Redox Flow Battery
Batteries &Supercaps, Volume 6, Issue 1, January 2023., 2023 Biobased: The filamentous fungus can be used as an environmentally and sustainable benign source to produce the bio‐based quinone phoenicin. This natural compound shows electrochemical properties, which can be used as the active material in the negative electrolyte in a redox flow battery with results showing that biologically produced quinones may ...

Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota
Angewandte Chemie, EarlyView.Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...
