Energy Science &Engineering, EarlyView.CFD analysis of a diesel–CH4–H2 tri‐fuel engine shows that increasing hydrogen energy share (HES) enhances mixing and accelerates combustion, improving pressure, efficiency, and reducing CO and soot. At 60% HES, ISFC improves 26.2%, soot drops 95%, while NOx increases due to higher temperatures. ABSTRACT The global commitment to achieve net‐zero carbon

Optimizing feather hydrolysate via machine learning for microbial recycling of waste concrete fines
Journal of Chemical Technology &Biotechnology, EarlyView.Abstract BACKGROUND The concrete industry faces significant challenges from CO2 emissions and the disposal of waste concrete fines (WCF). Microbially induced calcite precipitation (MICP) can bind WCF into bioconcrete, but the high cost of commercial culture media hinders its application.

Qualitative Analysis of Biogas by Raman Spectroscopy: Effect of Pressure on Major Components
Journal of Raman Spectroscopy, EarlyView.Raman spectra of major and selected minor biogas components were studied under pressures up to 100 bar. Pressure‐induced shifts and band broadening were quantified for methane, carbon dioxide, and nitrogen, while Raman spectra of ammonia and hydrogen sulfide are presented in the context of biogas quality monitoring.
