A single-atom platinum catalyst lights ammonia at 200 °C and keeps it burning steadily at 1,100 °C with low NO x, generating high-grade, carbon-free heat for steel, cement and chemicals. Ammonia is a ...

The amount of carbon dioxide detected in the atmosphere hit a record high in April. CO 2 levels averaged about 431 parts per million (ppm) over that month, according to data collected at the National ...

Urease, a nickel-dependent metalloenzyme produced by diverse pathogens, catalyses the hydrolysis of urea into ammonia and carbon dioxide, a reaction central to microbial survival in hostile ...

In 1988, the chickpeas and rice in this curry were part of a well-balanced meal — a serving of each provided a plethora of essential nutrients, including roughly 22 percent of the zinc a person needs ...

Researchers at the Council for Scientific and Industrial Research (CSIR) and the University of Stellenbosch have conducted a comparative life cycle assessment (LCA) to evaluate the environmental ...

Once held up as a key solution to climate change, a field that aims to remove carbon from the atmosphere is struggling to catch on. By David Gelles David has been writing about carbon removal ...

As humans burn fossil fuels and pump carbon dioxide into the atmosphere, we are heating up the planet. But there is another alarming impact of this climate pollution: it may be changing the chemistry ...

An ant that can turn carbon dioxide in the air into dolomite stone in its exoskeleton may hold clues to how humans can sequester greenhouse gases to avert climate disaster. Fungus-farming ants forage ...

Rising carbon dioxide levels are being detected within the human body, with new research warning a key blood marker for the gas could near its healthy limit within decades if current trends continue.

There is widespread recognition that efforts to meet global climate targets cannot be met by curbing new carbon dioxide emissions alone and will also require removing carbon from the atmosphere at ...

CF Industries, Trafigura and TFG Marine have signed a memorandum of understanding (MoU) to facilitate the adoption of low-carbon ammonia as a marine fuel. Building on the successful collaboration ...
