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 ...

Webb reveals cosmic cliffs, glittering landscape of star birth

This landscape of "mountains" and "valleys" speckled with glittering stars is actually the edge of a nearby, young, star-forming region called NGC 3324 in the Carina Nebula. Captured in infrared light by NASA's new James ...

Advocating a new paradigm for electron simulations

Although most fundamental mathematical equations that describe electronic structures are long known, they are too complex to be solved in practice. This has hampered progress in physics, chemistry and the material sciences. ...

Smuggling light through opaque materials

Electrical engineers at Duke University have discovered that changing the physical shape of a class of materials commonly used in electronics and near- and mid-infrared photonics—chalcogenide glasses— can extend their ...
