Perennial bioenergy grasses begin rebuilding Midwest soil carbon lost to maize
Nearly two centuries of maize-based agriculture in the U.S. Midwest has halved soil organic carbon (SOC) stocks compared with tallgrass prairies native to the region. Replacing annual maize/soy cropping with perennial bioenergy grasses may partially reverse these resulting SOC de

Researchers develop a new catalyst to convert CO₂ into ethanol using electricity
A research team led by Professor Hyoyoung Lee of the Department of Chemistry at Sungkyunkwan University has developed a new catalyst that converts carbon dioxide into ethanol with high selectivity. The study, titled "Atomic-scale Cu–Zn synergy directs asymmetric C–C coupling for
Catalyst converts CO₂ into high-value industrial chemical at room temperature with record
Catalyst converts CO₂ into high-value industrial chemical at room temperature with record
A research team has developed a highly efficient catalyst that directly converts carbon dioxide—a major contributor to global warming—into high-value industrial 2-propanol. The research was published online in Applied Catalysis B: Environment and Energy.
Long-term study suggests landfill methane emissions are far higher than estimates
Long-term study suggests landfill methane emissions are far higher than estimates
Methane is an especially potent greenhouse gas, causing much more warming than carbon dioxide on a unit-for-unit basis—and a new, uniquely long-term study of emissions at a New Jersey landfill suggests that estimates of methane pollution in the U.S. and elsewhere may be dramatica
Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
Carbon nanostructure improves fuel-cell catalyst durability while reducing platinum use
The explosion of new data centers being proposed and built around the U.S. has increased demand for energy to keep them powered and cooled. The Electric Power Research Institute estimates that data centers could consume up to 9% of U.S. electricity generation annually by 2030, up
Black silicon catalyst turns carbon dioxide into methane with sunlight
Black silicon catalyst turns carbon dioxide into methane with sunlight
Carbon dioxide is often viewed as a major contributor to climate change, but it can also become a valuable raw material. If scientists can efficiently convert carbon dioxide into useful fuels using sunlight, it would provide a sustainable way to store solar energy while reducing
It’s good for the planet to scrap a new petrol car and buy electric
It’s good for the planet to scrap a new petrol car and buy electric
Carbon savings from driving EVs are so large that it makes sense to scrap a working petrol car to make the switch O recorte ajuda a contextualizar a pauta dentro de Meio Ambiente.

Photocatalytic method cleaves strong C–H bonds while preserving weaker C–Si bonds
α-Silyl alcohols are unique organosilicon compounds bearing a silyl group and a hydroxy group on the same carbon atom. Because these compounds serve as precursors to reactive species, such as carbanions and carbon radicals, they are pivotal building blocks for synthesizing pharma

An ultramassive white dwarf half Earth's size may hold a rare oxygen-neon core
Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core determines how it will evolve. A paper outlining this di

Fridge-free tetanus-diphtheria vaccine shows promise of reaching millions worldwide
The encouraging results of the world's first trial of a fridge-free tetanus-diphtheria vaccine could improve access worldwide to crucial treatments while reducing carbon emissions. Fridge-free vaccines have the potential to transform vaccine delivery by reducing dependence on ref
