Olefin metathesis is one of the most important reactions in organic chemistry for forming carbon–carbon bonds—for example, in the production of pharmaceuticals, plastics and complex natural products. However, previous ruthenium catalysts that enable this reaction have faced a maj

Equipment to capture carbon dioxide from ambient air or smokestacks generally works through a sort of reversible filter. Air is passed through granules or a liquid that absorbs the CO 2 , then that CO 2 -loaded substance undergoes a process (usually heating) that causes it to let

Scientists have found that a famous 2-billion-year-old chemical signature, once thought to record a massive global change in Earth’s carbon cycle, may instead have been produced by local magma, hydrocarbons, and methane-eating microbes. The discovery raises new questions about wh

Some tropical trees have evolved a clever way to survive drought by taking in carbon dioxide at night, allowing them to keep their pores closed during the hot daytime and conserve water. By comparing three Clusia species, researchers discovered that this water-saving form of phot

Researchers have created a concrete mixture that is both stronger and capable of absorbing carbon dioxide. The best formula, combining zeolite with bamboo biochar, boosted compressive strength by 7.48% and tensile strength by 15% compared with conventional concrete. It also captu
