Simultaneous multi-gas detection needs only sub-μL analyte

Trace gas detection based on laser absorption spectroscopy (LAS) is a powerful technique due to its high sensitivity and selectivity, and it is widely used in many fields. Most of current works are performed using a single ...

Hunting for dark galaxies with FAST project

A large-scale neutral hydrogen (HI) survey of the local universe is one of the major science initiatives under the Five-hundred Meter Aperture Spherical radio Telescope (FAST) project.

Novel SERS method developed to capture target molecules

By constructing a multilayer nanoparticle film, researchers led by Prof. Yang Liangbao from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences (CAS) formed a natural gap of less than three nanometers ...

Advanced technology allows automated 3D tracking of leaked gas

Researchers have developed a way to create a 3D image of a leaked gas cloud that provides detailed information about the leak such as location, volume and concentration. The new automated detection approach could be used ...

Why are shallow lakes prone to eutrophication?

Anthropogenic eutrophication of lake ecosystems is a global problem, especially for some large shallow lakes. But scientists have been unclear why shallow lakes appear prone to eutrophication.
