Influence of shaft motor/generator on dynamic behavior of natural gas/diesel dual-fuel engine in ship hybrid propulsion system under various operating conditions

open access: yesInternational Journal of Naval Architecture and Ocean Engineering
To reduce shipping emissions, natural gas is a viable alternative fuel for marine engines. However, natural gas (or natural gas/diesel dual-fuel) engines exhibit poor dynamic performance, potentially compromising ship safety in adverse conditions.

Escaping the Scaling Relationships in Oxygen Reduction Catalysis: Implications for PEM Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Escaping the scaling relationships of the oxygen reduction reaction is vital for hydrogen fuel cells. This outlook examines how interfacial heterogeneity, spanning the subsurface lattice, chemisorption layer, and near‐interface solvation volume, mechanistically decouples intermediate binding energetics.

Electrochromic Adaptive Solar Heater and Sub‐Ambient Passive Daytime Radiative Cooler

open access: yesAdvanced Materials, EarlyView.
An electrochromic Cu–Bi nanocluster device dynamically switches between solar heating and daytime sub‐ambient radiative cooling without mechanical motion. Defect‐activated graphene, minimized electrolyte loss, and pulse‐assisted reversible electrodeposition enable opposite solar and mid‐infrared modulation in one opaque platform, establishing a design ...

Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater

open access: yesAdvanced Materials, EarlyView.
Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.

Adsorption‐Engineered Hydrocarbon Ionomers for Durable Proton‐Exchange Membrane Fuel Cells

open access: yesAdvanced Materials, EarlyView.
Hydrocarbon ionomers suffer from oxidation‐driven interfacial degradation in PEM fuel cell cathodes, leading to catalyst instability. Here, adsorption‐engineered poly(fluorene) ionomers decouple interfacial anchoring from oxidative degradation, enabling strong catalyst–ionomer interactions while resisting electrochemical oxidation.

Adaptive Fuel System of a Tractor with Dual-fuel Mode

open access: yesMachinery and Equipment for Rural Area
The article considers the possibility of using biodiesel fuel (of biodiesel) for the agricultural machinery engines. The Key parameters that need to be taken into account when choosing a fuel mixture are described. Particular attention is paid to the effect of biodiesel on engine power and the need to adjust the amount of biofuel supplied.
