Biowaste Composting as a Sustainable Platform for Bacterial CO Production: Evidence From cooS Gene Expression and Microbial Community Profiling

open access: yesGCB Bioenergy, Volume 18, Issue 5, May 2026.
This study demonstrates, for the first time, the expression of the cooS gene during composting, confirming microbial CO production under mesophilic conditions. The results highlight composting as a novel waste‐to‐biochemicals process, offering a sustainable, low‐carbon pathway for generating carbon monoxide via bacterial CO dehydrogenase activity ...

Current evaluation of the tripropellant concept [PDF]

open access: yes
An analytical study was conducted to determine the specific-impulse advantages of adding metals to conventional liquid-bipropellant systems. These tripropellant systems theoretically offer higher specific impulse and increased propellant density compared

From the Modeling of Experiments to the Ab Initio Prediction of Rate Constants: Statistical Rate Theory for a Quantitative Understanding of Gas‐Phase Ion Chemistry

open access: yesChemPhysChem, Volume 27, Issue 8, 28 April 2026.
For directly comparing experimental results on gas‐phase ion reactions with the predictions from quantum chemical calculations, the latter must first be converted into rate constants. This review addresses the question of whether current methods of statistical rate theory can accomplish this task reliably. Statistical rate theory has long been used for

Thermochemical cycle analysis using linked CECS72 and HYDRGN computer programs [PDF]

open access: yes
A combined thermochemical cycle analysis computer program was designed. Input to the combined program is the same as input to the thermochemical cycle analysis program except that the extent of the reactions need not be specified. The combined program is

Multiple Dimerization Modes in Thiocarboxylate Paddlewheel Complexes: A Comprehensive View of Energy Landscapes from DFT Calculations and Statistics

open access: yesChemistry – A European Journal, Volume 32, Issue 15, 22 April 2026.
Staggered, square, and heavily bent dimers occur in the five known solvatomorphs of paddlewheel (PW) complex [PtVO(SOCPh)4]. These and other structural motifs are well within energetic reach due to the shallow potential energy surface that guides dimerization and are included in a revised classification of available structural data on heterobimetallic ...
