Biomass char gasification for hydrogen production: A thermodynamic equilibrium analysis

open access: yesFuel Processing Technology
Hydrogen can be produced from biomass via thermochemical conversion, either through direct gasification of raw biomass or a two-step process involving pyrolysis to generate char, followed by char gasification. The latter process reduces tar contamination

CEO Managerial Ability and the Strategic Repetition of Climate Disclosures

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines whether CEO managerial ability shapes the repetition of firms' climate‐related disclosures in mandatory 10‐K filings. Climate reporting is highly judgment based and central to firms' broader climate‐risk management strategies, yet little is known about why some firms repeatedly use similar climate narratives and others ...

Regulating Interfacial Water Structure on CoNi/MoN Heterostructures Boosts Electrocatalytic Nitrate Reduction to Ammonia

open access: yesCarbon Energy, EarlyView.
The CoNi/MoN interface effect induces electron transfer from CoNi species to MoN nanosheets, in which electron‐enriched CoNi/MoN interface captures K+ to form K+‐H2O, facilitating H2O dissociation to provide *H for accelerating hydrogenation steps, while electron‐deficient CoNi nanoparticles enhances the NO3− adsorption and reduces the free energy ...
