Solutions for methane mitigation in Brazilian agriculture: achieving a 28% reduction by 2035

Frontiers in Sustainable Food Systems
Brazil is the world’s fifth-largest methane emitter, with methane accounting for 24% of national greenhouse gas emissions and the agricultural sector responsible for 75.6% of these methane emissions, mainly from livestock.

Force‐Induced Control of Circularly Polarized Luminescence With Rotaxane Architecture

Angewandte Chemie, EarlyView.
Force‐induced reversible on/off switching of circularly polarized luminescence is achieved with a rotaxane‐based supramolecular mechanophore. The mechanophore, featuring a chiral helicene luminophore, is incorporated as a first network cross‐linker into a double‐network organogel.

Cycloazulenylen

Angewandte Chemie, EarlyView.
Ein ausschließlich aus Azulen‐Untereinheiten aufgebauter gespannter Makrocyclus mit der Bezeichnung [6]Cycloparaazulenylen ([6]CPA) wird vorgestellt. Der Makrocyclus weist für ein Azulensystem eine bemerkenswert kleine HOMO–LUMO‐Energielücke, eine durch die Ringspannung hervorgerufene bathochrome Verschiebung der Absorption sowie ein ungewöhnliches ...

Waterfalls enhance regional methane emissions by enabling dissolved methane to bypass microbial oxidation

Communications Earth & Environment
River waters are significant sources of atmospheric methane whose local emissions increase with river slope and turbulence. However, when integrated regionally, the amount of dissolved methane released to the atmosphere is uninfluenced by local changes ...

Methanotrophy: A Biological Method to Mitigate Global Methane Emission

Microbiology Research
Methanotrophy is a biological process that effectively reduces global methane emissions by utilizing microorganisms that can utilize methane as a source of energy under both oxic and anoxic conditions, using a variety of different electron acceptors ...

Impact of methane emissions on greenhouse gas emissions in selected sub-Saharan African countries: a comprehensive analysis and policy framework for mitigation strategies

Environmental Sciences Europe
Greenhouse gas (GHG) emissions have a major impact on the environment, human health, and climate change. In addition, methane (CH4) is the second most prevalent greenhouse gas in the world, after carbon dioxide (CO2).This study investigates how methane ...

Cycloazulenylene

Angewandte Chemie International Edition, EarlyView.
A strained macrocycle consisting solely of azulene subunits, named [6]cycloparaazulenylene ([6]CPA), is presented. The macrocycle exhibits a notably narrow HOMO–LUMO gap for a pristine azulene species, strain‐induced red‐shifted absorption, and an unusual tubular packing motif elucidated via single‐crystal XRD.

Wetlands’ Methane Emissions

This research aimed to enhance the accuracy of methane (CH₄) emissions estimates from natural wetlands by integrating satellite observations and advanced modeling techniques. Wetlands are among the largest natural sources of CH₄. However, current estimates carry large uncertainties due to the spatial and temporal variability of wetland characteristics.
