“#Biobased chemicals take center stage” Usually, when oil prices fall, biobased chemical firms struggle. But these days, alternatives to petroleum-based products are undergoing a renaissance. Consumers are increasingly eco-conscious, leading companies to partner with chemical manufacturers to develop products that are both sustainable and high performing. A new article in Chemical & Engineering News, the…
“#Learning more about particle collisions with machine learning” Schematic of ATLAS detector in the Large Hadron Collider. Credit: ATLAS Collaboration The Large Hadron Collider (LHC) near Geneva, Switzerland became famous around the world in 2012 with the detection of the Higgs boson. The observation marked a crucial confirmation of the Standard Model of particle physics,…
“#Physicists use oscillations of atoms to control a phase transition” Artist’s impression of the phase transition of indium atoms on a silicon crystal controlled by light pulses. Credit: Dr Murat Sivis The goal of ‘femtochemistry’ is to film and control chemical reactions with short flashes of light. Using consecutive laser pulses, atomic bonds can be…
“#Texas will face driest conditions of the last 1,000 years” Credit: Pixabay/CC0 Public Domain Texas’ future climate will feature drier summers and decreasing water supplies for much of the state for the remainder of the 21st century—likely resulting in the driest conditions the state has endured in the last 1,000 years, according to a team…
“#Soil studies can be helpful for border control” A soil tunnel shaft is used to access a tunnel under the U.S.-Mexico border.
