Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension

Potential contribution of biomass gasification‐based technology in energy transition: a technical review coupled with bibliometric studies

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract Biomass gasification technology has been extensively researched around the world; however, there is a need to evaluate the current research landscape and evolutionary direction of research in the broader context of energy transition. A systematic bibliometric analysis of the Web of Science database was performed for articles that fall within ...

Subterranean environments contribute to three‐quarters of classified ecosystem services

open access: yesBiological Reviews, EarlyView.
ABSTRACT Beneath the Earth's surface lies a network of interconnected caves, voids, and systems of fissures forming in rocks of sedimentary, igneous, or metamorphic origin. Although largely inaccessible to humans, this hidden realm supports and regulates services critical to ecological health and human well‐being.

Global Energy Corporations and Climate Change: The Role of Formal and Informal Institutions in Shaping Climate Change Risk Disclosure

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines climate change risk disclosure in the global energy sector, where firms face intense stakeholder scrutiny and legitimacy pressures. We develop a novel domain‐specific textual analysis measure to capture climate change risk disclosures, improving on prior approaches based on generic environmental terminology.

Selective Synthesis of N,N‐Dimethylformamide From CO2 Hydrogenation Coupled With Dimethylamine Over a ZnZrOx Solid‐Solution Catalyst

open access: yesCarbon and Hydrogen, EarlyView.
N‐formylation of dimethylamine though CO2 hydrogenation takes place at a ZnZrOx solid‐solution catalyst surface toward N,N‐dimethylformamide. By synergistic effect of Zn and Zr sites, the catalyst achieves 99% DMF selectivity at 14% DMA conversion at 280°C with at least 1000 h stability on steam.

Machine Learning‐Driven Prediction and Optimization of Cu‐Based Catalysts for CO2 Hydrogenation to Methanol

open access: yesCarbon and Hydrogen, EarlyView.
A machine‐learning framework integrating multimodel prediction, feature selection, and SHAP interpretability is developed to uncover structure–performance relationships of Cu‐based CO2‐to‐methanol catalysts. The optimized XGBoost model and an online prediction platform enable accurate selectivity prediction and data‐driven catalyst design.
