Partnership develops technology to convert methane gas, a common by-product of oil production, into methanol
Most people realize the climate impacts of carbon dioxide. Not many people, however, know that methane, the main component of natural gas, is much more potent than carbon dioxide. While methane doesn’t remain in the atmosphere as long as CO2 (which can linger for thousands of years), it is 84 ...
A new way to tackle 'forever chemicals'
Per- and polyfluoroalkyl substances (PFAS) are potentially harmful substances known as “forever chemicals” because they are so difficult to destroy. One emerging technique to degrade PFAS involves forcefully grinding them with metal balls in a moving container, but this technique can require ...
Creates Transformative Platform to Address World’s Most Critical Water Challenges
Xylem Inc. and Evoqua announced they have entered into a definitive agreement under which Xylem will acquire Evoqua in an all-stock transaction that reflects an implied enterprise value of approximately $7.5 billion. As water risks rise in global importance, this transaction unites two companies ...
New process for making catenanes for potential use in airplanes, armor and other resilient needs
University of California, Berkeley, chemists have created a new type of material from millions of identical, interlocking molecules that for the first time allows the synthesis of extensive 2D or 3D structures that are flexible, strong and resilient, like the chain mail that protected medieval ...
Researchers captured extremely fast dynamics
In salt water solutions, water molecules rapidly move around salt ions at a scale of more than a trillion times a second, according to both experiments and simulations led by scientists at New York University and the Sorbonne. “There is more to salt solutions than meets the eye,” said Alexej ...
Illuminating study advances ‘green’ reducing agents
There are many ways to initiate chemical reactions in liquids, but placing free electrons directly into water, ammonia and other liquid solutions is especially attractive for green chemistry becausesolvated electrons are inherently clean, leaving behind no side products after they react. In ...
Researchers used artificial intelligence to rapidly discover new self-assembled nanostructures
Scientists at the U.S. Department of Energy’s (DOE) Brookhaven National Laboratory have successfully demonstrated that autonomous methods can discover new materials. Theartificial intelligence(AI)-driven technique led to the discovery of three new nanostructures, including a first-of-its-kind ...
New method creates useful char from plastic and corn waste
University of California, Riverside, scientists have moved a step closer to finding a use for the hundreds of millions of tons of plastic waste produced every year that often winds up clogging streams and rivers and polluting our oceans. In a recent study, Kandis Leslie Abdul-Aziz, a UCR ...
BASF launches final expansion phase: total investment of around $1 billion
BASF has broken ground on the third and final phase of the methylene diphenyl diisocyanate (MDI) expansion project at its Verbund site in Geismar, Louisiana, announced in July 2022. The company will increase production capacity to approximately 600,000 metric tons per year by the middle of the ...
Photochemistry method eases manufacture of drug, chemical precursors
Inexpensive iron salts are a key to simplifying the manufacture of essential precursors for drugs and other chemicals, according to scientists at Rice University. They’ve refined the process of producing diazides, building-block molecules in the production of drugs and agricultural chemicals. ...
