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

International 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.

Rational Fine‐Tuning of MOF Pore Metrics: Enhanced SO2 Capture and Sensing with Optimal Multi‐Site Interactions

Advanced Functional Materials, EarlyView.
A pore tuning strategy to amplify the multi‐site MOF‐SO2 interactions is proposed to achieve an enhanced trace SO2 capture and chemiresistive sensing in highly stable isostructural DMOFs by annelating benzene rings. This work provides a facile strategy to achieve tailor‐made stable MOF materials for specific multifunctional applications.

Modulating Electrochemical CO2 Reduction Pathways via Interfacial Electric Field

Advanced Functional Materials, EarlyView.
Engineering interfacial electric fields in Cu/ITO electrodes enables precise control of CO2 reduction pathways. Charge transfer from Cu to ITO generates positively charged Cu species that steer selectivity from ethylene toward methane. This work demonstrates how interfacial electric‐field modulation can direct reaction intermediates and transform ...

Hydrogen for dual fuel engine operation

International Journal of Hydrogen Energy, 1983
Abstract In this investigation, an attempt was made to burn hydrogen in compression ignition engines that were operated on a dual fuel principle. Hydrogen was supplied along with intake air in small proportions and ignition was initiated by injecting diesel fuel in the conventional manner.
