Air Emissions of Ammonia and Methane from Livestock Operations: Valuation and Policy Options [PDF]

The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter—arguably, the number-one environment-related public health

Methane Emission from Rice Fields: Necessity for Molecular Approach for Mitigation

Rice Science
Anthropogenic methane emissions are a leading cause of the increase in global average temperatures, often referred to as global warming. Flooded soils play a significant role in methane production, where the anaerobic conditions promote the production of

Ferroelectric Catalysts in the Hydrogen Evolution Reaction: A Perspective

Advanced Science, EarlyView.
This perspective summarizes recent advances in ferroelectric (FE) catalysts for the hydrogen evolution reaction (HER). It first introduces HER fundamentals and FE mechanisms, then classifies FE catalysts into single‐phase, single‐atom‐modified, heterostructured, and other engineered types, with representative examples.

Chlorine‐Functionalized Silane‐Modified Copper Electrocatalyst for Enhanced CO2 Reduction to Multi‐Carbon Products

Advanced Science, EarlyView.
A chlorine‐functionalized silane modifier (CPTMS) is introduced to cooperatively regulate CO2 reduction to C2+ products on Cu‐based catalysts. Dual‐functional interface sequentially enhances CO2 activation, intermediates protonation and C─C coupling, delivering a 5‐fold increase in C2+ faradaic efficiency (FE, 75% vs.

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

Advanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

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

Discover 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

Journal 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

Intrinsic Phonons as a Dynamic Control Knob for Catalytic Reactivity in 2D Materials

Advanced Science, EarlyView.
Intrinsic phonon excitations are demonstrated to serve as a dynamic control knob for catalytic reactivity in 2D materials. Mode‐selective lattice vibrations reconstruct the electronic structure, lower oxygen evolution reaction barriers, establishing a phonon‐engineering paradigm for dynamically regulating electrocatalysis beyond conventional static ...

Ru‐Doping‐Engineered Oxygen Vacancies in MoO3‐x Nanostructured Films With Ultrahigh Capacitance for Flexible Asymmetric Supercapacitors

Advanced Science, EarlyView.
Ru‐doping‐induced defect engineering enables freestanding Ru–MoO3‐x flexible films with enriched oxygen vacancies, modulated band structure, and enhanced charge transport. The optimized electrode delivers ultrahigh capacitance approaching the theoretical limit of MoO3, while assembled asymmetric supercapacitors exhibit high energy density, wide‐voltage

Methane Emission Control

Johnson Matthey Technology Review, 2016
Natural gas is of increasing interest as an alternative fuel for vehicles and stationary engines that traditionally use gasoline and diesel fuels. Drivers for the adoption of natural gas include high abundance, lower price and reduced greenhouse gas emissions compared to other fossil fuels. Biogas is an option which could reduce such emissions further.
