Reducing Agent

Geological observations of Mars indicate a dense early atmosphere ranging from 0.25 to 4 bar of carbon dioxide.

Samarium diiodide (SmI2) is a privileged, single-electron reductant deployed in diverse synthetic settings. However, generalizable methods for catalytic turnover remain elusive because of the well-known challenge associated with cleaving strong SmIII–O ...

Partnership will deliver AI-powered solutions to address the complexity of modern contact centers and help eliminate outages, downtime, and broken customer journeys

Photosynthesis is the greatest natural process on Earth, converting sunlight into chemical energy on a massive scale and maintaining life. There are basically two successive stages of oxygenic photosynthesis, of which the light-dependent reactions in photosystem II (PSII), and in photosystem I (PSI), enable the oxidation of H2O into molecular oxygen, and production of reducing power (NADPH and ATP), while CO2…

The harmonious coexistence between human society and nature has prompted the rapid development of advanced manufacturing. Typically, green biomanufacturing, which uses renewable resources as raw materials and enzymes or microorganisms as catalysts to produce target chemicals, has been considered to be highly consistent with the 12 principles of green chemistry. Specifically, enzyme-based green biomanufacturing has…

NASA's Perseverance rover found strange green spots in Martian rock, potentially indicating a past interaction with liquid water.

The search for habitable exoplanets involves looking for planets with similar conditions to the Earth, such as liquid water, a suitable temperature range and atmospheric conditions. One crucial factor is the planet's position in the habitable zone, the region around a star where liquid water could potentially exist on the planet's surface.

Astronomers are working hard to understand biosignatures and how they indicate life's presence on an exoplanet. But each planet we encounter is a unique puzzle. When it comes to planetary atmospheres, carbon is a big piece of the puzzle because it has a powerful effect on climate and biogeochemistry. If scientists can figure out how and where a planet's carbon comes from and how it behaves in the atmosphere,…

Clean energy is the leading solution for climate change. But solar and wind power are inconsistent at producing enough energy for a reliable power grid. Alternatively, lithium-ion batteries can store energy but are a limited resource.

It's not hard to find some crazy trends on TikTok, often involving health claims. But how many can be turned into a Dreaded Chemistry Lesson From Hell? Here's the first, along with reasons not to take methylene blue supplements.

Here's how the spacecraft will investigate whether the icy moon has life

MIT research suggests Mars' missing atmosphere — which dramatically diminished 3.5 billion years ago — could be locked in the planet's clay-covered crust. Water on Mars could have set off a chain reaction that drew CO2 out of the atmosphere and converted it into methane within clay minerals.

Researchers have designed a new graphene-based biosensor that can accurately detect the freshness of meat.

Saturn's ocean moon, Enceladus, is attracting increasing attention in the search for life in our solar system. Most of what we know about Enceladus and its ice-covered ocean comes from the Cassini mission. Cassini ended its exploration of the Saturn system in 2017, but scientists are still working through its data.

A new study at Umeå University provides insight into how mercury transforms into its more toxic form, methylmercury, with the help of small sulfur-containing substances known as thiols.

The use of dicamba, an herbicide, has become an extremely contentious issue in some farm states. It has been accused of "tearing apart the fabric of rural life." The issues surrounding dicamba present a fascinating study on modern agriculture and problems that arise when technological advances impact farming choices and basic livelihood.
