Interfacial Salinity–Transport Matching in 3D Solar Evaporators: A Framework for Brine‐Stable Solar Interfacial Evaporation

open access: yesAdvanced Science, EarlyView.
A transport‐matching framework is developed to evaluate brine‐stable 3D solar evaporators beyond evaporation rate alone. Using PVA/GNP porous evaporators as a model system, the study shows that stable brine evaporation requires balanced heat generation, liquid replenishment, salt redistribution, and vapor removal rather than maximum dry temperature or ...

Emission factors for methane engines on vehicles and ships : with a focus on methane emissions

open access: yes, 2020
Den här rapporten beskriver emissioner från metanmotorer på vägfordon och fartyg. Syftet är att ta fram relevanta emissionsfaktorer för olika motortyper och fordonstyper, alternativt fartyg. Fokuset är att presentera emissionsfaktorer för metanutsläpp och uppskattningarna omfattar både emissioner från motorer och från bränslesystemen ombord.

Scalable Fabrication of MOF Glass Membranes for Gas Separation via Stepwise Phase Transition

open access: yesAdvanced Science, EarlyView.
Metal‐organic framework (MOF) glass membranes, with their excellent processability and permanent pore structure, have great potential for gas separation applications. However, during large‐scale fabrication, defects and obvious cracks are prone to occur due to the limitations of powder processing.

Protonation Modification of Commercial OPBI as Binders Toward High‐Performance High‐Temperature PEM Fuel Cells

open access: yesAdvanced Science, EarlyView.
Commercial OPBI binders is regulated via a facile formic‐acid protonation strategy without disrupting the polymer backbone. Protonation introduces positively charged benzimidazole sites, inducing interchain electrostatic repulsion that loosens chain packing, enlarges intermolecular spacing, and promotes uniform binder dispersion over catalyst surfaces.

Mitigating methane emissions in rice (Oryza sativa) farming systems: a breeding and management roadmap for low-emission genotypes in Sub-Saharan Africa

open access: yesDiscover Agriculture
Rice cultivation is a significant source of methane emissions in the agriculture sector in Sub-Saharan Africa (SSA). In Africa, rice is grown in flooded conditions, which promote the release of methane by methanogens that use organic exudates from the ...

Effects of lactation stage and behavioral activity on enteric methane emissions in dairy cows

open access: yesJournal of Dairy Science
: This study investigated how the lactation stage and the main behavioral activities of dairy cows influence enteric methane emissions. The research trial was conducted on 39 Italian Simmental dairy cows reared in a commercial dairy farm. Each animal was

Molecular Electrocatalysis Coupled With a Palladium Membrane Reactor Affords Selective Nitrogen Reduction

open access: yesAdvanced Science, EarlyView.
A palladium membrane reactor delivers active hydrogen to homogeneous nickel terpyridine catalysts, which then selectively hydrogenate dinitrogen to ammonia. ABSTRACT Ammonia production is a cornerstone of modern industry and society, yet the conventional Haber–Bosch process accounts for nearly 2% of the global CO2 emissions. A promising and potentially

Transforming Gas Separations with Scalable Carbon Molecular Sieve Membranes Enabled by Chemically Tuned Hollow‐Fiber Precursors

open access: yesAdvanced Science, EarlyView.
We established a broadly tunable network‐polymer platform for polyimide‐based precursor membranes, extendable to various diamines. Ultrahigh selectivity with demonstrated aging resistance, and scalability via hollow fiber CMS engineering collectively establishes broad and lasting impact for the membrane science and engineering communities.

Analysing the linear and nonlinear impact of rice production and trade openness on methane emissions in India

open access: yesDiscover Environment
India, being one of the largest producers of rice, contributes significantly to global methane emissions. Simultaneously, trade openness influences production intensity, which accelerates methane emissions.
