The link between wildfires and drinking water contamination

Following a devastating wildfire in 2018 that raged through Paradise, California, volatile organic compounds (VOCs) were found to be contaminating the town's water—and scientists suggest this problem may be widespread in ...

'E-nose' sniffs out mixtures of volatile organic compounds

As paint thinner, ink and adhesives dry, they can release volatile organic compounds (VOCs), which can negatively impact health. Typically, one of those VOCs is xylene, which exists as three isomers with the same elements ...

Scientists make toxic gas sensing nine times more effective

A Russian-Belorussian research team has developed a new tungsten oxide–based gas sensing material that shows high sensitivity to carbon monoxide, nitrogen dioxide and acetone. The new material's gas sensing response was ...

A new tool to verify the geographical origins of virgin olive oil

Olive oil is one of the most prestigious agri-foods in Spain and it is the base of the Mediterranean diet. Adulteration and commercial fraud cases occur when it comes to the origin and varieties of a product with such an ...

A highly sensitive SERS substrate for gas sensing

Trace gas sensing is critical for monitoring environmental pollution and detecting volatile organic compounds released from the human body. As a powerful analytical tool for identifying trace molecules, surface-enhanced Raman ...

Scientists begin studying 50-year-old frozen Apollo 17 samples

Scientists at NASA's Goddard Space Flight Center in Greenbelt, Maryland, recently received samples of the lunar surface that have been curated in a freezer at NASA's Johnson Space Center in Houston since Apollo 17 astronauts ...
