Uniquely precise: New value for the half-life of samarium-146

Researchers at the Paul Scherrer Institute PSI and the Australian National University have re-determined the half-life of samarium-146 with great precision. The result fits perfectly with the data astrophysicists and geochemists ...

Probing carbon capture, atom-by-atom with machine-learning model

A team of scientists at Lawrence Livermore National Laboratory (LLNL) has developed a machine-learning model to gain an atomic-level understanding of CO2 capture in amine-based sorbents. This innovative approach promises ...

Scent research inspires bed bug trap

Scientists at London School of Hygiene & Tropical Medicine (LSHTM) spinout Arctech Innovation have used their in-depth knowledge of insects, chemistry and odor to develop a new trap for bed bugs.

Elusive predicted water structure created in the laboratory

Clathrate hydrates are complex water structures that contain foreign guest molecules inside a host water-molecule shell. A predicted clathrate hydrate phase structure has been stably synthesized in the lab and may play an ...

New method detects environmentally unfriendly chemicals

Substances called polyethylene glycols, or PEGs, are widely used in industry, medical, cosmetics and personal care products. The problem is, when they enter the environment and build up, they can harm ecosystems and natural ...

Raman spectroscopy offers new insights into ionic liquid acidity

Researchers at the University of Liège have for the first time determined the acidity of ionic liquids using Raman spectroscopy, thanks to Hammett acidity functions. This advance promises to revolutionize our understanding ...

Ice 0: Researchers discover a new mechanism for ice formation

Ice is far more complicated than most of us realize, with over 20 different varieties known to science, forming under various combinations of pressure and temperature. The kind we use to chill our drinks is known as ice I, ...

Shining light on similar crystals reveals photoreactions can differ

A rose by any other name is a rose, but what of a crystal? Osaka Metropolitan University-led researchers have found that single crystals of four anthracene derivatives with different substituents react differently when irradiated ...
