Extreme UV laser shows generation of atmospheric pollutant

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and photochemical smog. The technique, ...

New scale for electronegativity rewrites the chemistry textbook

Electronegativity is one of the most well-known models for explaining why chemical reactions occur. Now, Martin Rahm from Chalmers University of Technology, Sweden, has redefined the concept with a new, more comprehensive ...

WUSTL engineers provide free code to help build better batteries

(Phys.org) —Lithium-ion batteries, such as those used in electric vehicles, are in high demand, with a global market value expected to reach $33.1 billion in 2019. But their high price and short life need to be addressed ...

Existence of new element confirmed

Remember the periodic table from chemistry class in school? Researchers from Lund University in Sweden have presented fresh evidence that confirms the existence of a previously unknown chemical element. The new, super-heavy ...

Unraveling bacterial behavior

Bacteria encounter a constant barrage of ever-changing temperature, acidity and chemical stimuli from their environment. The cells must absorb all of this information and choose the correct response—whether boosting their ...

Researchers create world's smallest reaction chamber

The world's smallest reaction chamber, with a mixing volume measured in femtolitres (million billionths of a litre), can be used to study the kind of speedy, nanoscale biochemical reactions that take place inside individual ...

Non-equilibrium quantum states in atmospheric chemistry

(Phys.org)—Research that sheds new light on the microscopic chemical physics driving one of the most important reaction sequences in atmospheric chemistry is published in Science today by Dr David Glowacki from the University ...

'Google on steroids': Scientists create chemical brain

Northwestern University scientists have connected 250 years of organic chemical knowledge into one giant computer network -- a chemical Google on steroids. This "immortal chemist" will never retire and take away its knowledge ...
