Photocoupled electroreduction of CO2 over photosensitizer decorated covalent organic frameworks
Electrocatalytic CO2 reduction reaction (CO2RR) is thought to be an ecologically favorable technique for using CO2 as a cheap and abundant C1 feedstock for the production of value-added chemicals such as CO. However, the thermodynamically stable natu.....»»
Curbside collection improves organic waste composting, reduces methane emissions
Most organic household waste ends up in landfills, where it generates methane, a powerful greenhouse gas. Composting food and garden waste instead of sending it to landfills can significantly reduce methane emissions and help mitigate global warming......»»
New study reveals influencers of global biogenic volatile organic compound emission trends over the last 20 years
Biogenic volatile organic compounds (BVOCs) emitted by vegetation are important precursors of ozone and secondary organic aerosols in the atmosphere, affecting air quality, clouds, and climate. However, BVOC emissions remain highly uncertain because.....»»
Additional nutrients intensify dead zones in oceans, researchers find
As more and more nutrients from land and air enter the world's oceans, the dead zones without oxygen in the water will increase in size and intensity. That is the warning that Ph.D. student Zoë van Kemenade, an organic geochemist at NIOZ, draws from.....»»
Scientists discover methods to regulate carbon storage in humus layer of forest in north China
It is estimated that 30% of the world's terrestrial carbon stocks are found in the boreal forest, 60% of which is below ground. Organic soil horizons contain about one-third of the soil carbon. Therefore, the stability of boreal soils is critical to.....»»
New research shows unintended harms of organic farming
Organic farming is often touted as a more sustainable solution for food production, leveraging natural forms of pest control to promote eco-friendly cultivation......»»

Transforming wood waste for sustainable manufacturing
Lignin, a complex organic polymer, is one of the main components of wood, providing structural support and rigidity to make trees strong enough to withstand the elements. When transforming wood into paper, lignin is a key ingredient that must be remo.....»»
Pesticide-free as a new pathway for agriculture
A new approach is gaining momentum in European agriculture: a "third way" that lies between conventional production and organic farming systems. Here farmers must forego synthetic pesticides only—which is simpler to implement than a switch to organ.....»»
Harnessing the power of privacy-enhancing tech for safer AI adoption
A consensus on regulatory AI frameworks seems distant. Yet, the imperative for secure and responsible AI deployment cannot be overstated. How can leaders proactively address AI adoption challenges while waiting for regulatory clarity? In this Help Ne.....»»
Photocatalytic synthesis of arylacetic acid via C=C double bond cleavage with carbon dioxide
Alkenes represent one of the most abundant classes of organic molecules, which are available in bulk quantities from petroleum and renewable resources, with various utilization in agrochemistry, pharmacy, and organic materials. Typically, the transfo.....»»
Revealing environmental exposure to liquid crystal monomers from digital displays
Liquid crystal monomers (LCMs) are synthetic organic chemicals used in manufacturing liquid crystal displays (LCDs) present in numerous digital electronic devices. As the use of digital electronics, such as computers and smartphones, becomes increasi.....»»
Increasing soil organic matter to improve soil health, carbon storage
Soil organic matter (SOM) is crucial to soil health and carbon storage in agriculture. Adding crop residues to the soil increases SOM, but can also accelerate its decomposition, known as the priming effect. The temperature sensitivity (Q10) of SOM de.....»»
