More Colorado communities take "forever chemical" makers to court as contamination costs mount
They stand at least 30 feet tall and 10 feet across, eight giant baby blue tanks filled with what is this fast-growing town's best defense against a glut of industrial cancer-causing chemicals that have been accumulating and percolating for half a ce.....»»
Recent advances in electrocatalytic ammonia synthesis
NH3 is the second largest chemical produced in the world and nearly 80% of produced NH3 is employed in fertilizer synthesis. Meanwhile, NH3 is an indispensable raw material for manufacturing nitric acid, which can be further employed in chemical prod.....»»
It"s so metal: Scientists confirm nickel plays a key role in an ancient chemical reaction
Carbon dioxide (CO2) is the most abundant greenhouse gas causing climate change but has existed on Earth long before humans started releasing it into the atmosphere at unprecedented levels. As such, some of the planet's earliest organisms evolved to.....»»
A promising approach in sustainable chemical production
Carbon capture and utilization (CCU) technologies are crucial for addressing climate change while ensuring economic viability. MES has emerged as a promising approach for CO2 reduction to biofuels and platform chemicals. However, the industrial adopt.....»»
Study demonstrates many-body chemical reactions in a quantum degenerate gas
In recent years, physicists have been trying to attain the control of chemical reactions in the quantum degenerate regime, where de Broglie wavelength of particles becomes comparable to the spacing between them. Theoretical predictions suggest that m.....»»
Researchers visualize novel catalyst at work
A novel catalysis scheme enables chemical reactions that were previously virtually impossible. A method developed at the University of Bonn is also environmentally friendly and does not require rare and precious metals......»»
Testing of Vlad the Impaler"s letters show he may have had condition causing his tears to be mixed with blood
A team of chemical scientists from the University of Catania, SpringStyle Tech Design Ltd, Romania National Archives and Politecnico di Milano, Via Mancinelli, has found evidence suggesting that Vlad the Impaler, may have suffered from a variety of a.....»»
Turning ChatGPT into a "chemistry assistant"
Developing new materials requires significant time and labor, but some chemists are now hopeful that artificial intelligence (AI) could one day shoulder much of this burden. In a new study in the Journal of the American Chemical Society, a team promp.....»»
New calcium material functions as an ammonia synthesis catalyst
Researchers find calcium outshines chromium in the catalytic production of ammonia. Working together, a humble trio of calcium atoms have defied expectations to break apart one of the strongest chemical bonds known. The atoms form the key part of a c.....»»
App-based tool quantifies pesticide toxicity in watersheds, identifies mitigation opportunities
Pesticides are a leading source of chemical hazards in aquatic environments. A study published in PLOS Water by Nicol Parker and Arturo A Keller at University of California, Santa Barbara, and colleagues introduces a new tool to help evaluate toxicit.....»»
Researchers use enzymes to develop a new class of materials for biocatalytic processes
Industrial biocatalysis with enzymes is deemed to be a "game changer" in the development of a sustainable chemical industry. Enzymes can be used to synthesize an impressive range of complex molecules, including pharmaceutical substances, under enviro.....»»
Chemical contamination on International Space Station is out of this world, study shows
Concentrations of potentially harmful chemical compounds in dust collected from air filtration systems on the International Space Station (ISS) exceed those found in floor dust from many American homes, a new study reveals......»»
Experiments identify important new role of chemical compounds in plant development
Researchers who manipulate lignin, a molecular fiber that allows plants to grow tall and transport water, unexpectedly discovered its synthesis has more far-reaching effects on plant development than previously suspected......»»
Deep learning for new protein design
The key to understanding proteins—such as those that govern cancer, COVID-19, and other diseases—is quite simple: Identify their chemical structure and find which other proteins can bind to them. But there's a catch......»»
New, simple and accessible method creates potency-increasing structure in drugs
Chemical structures called cyclopropanes can increase the potency and fine-tune the properties of many drugs, but traditional methods to create this structure only work with certain molecules and require highly reactive—potentially explosive—ingr.....»»
