A new filter for infrared light could see scanning and screening technology fall in price and size. Built on nanotechnology, the new heat-tunable filter promises hand-held, robust technology to ...

Recent spectroscopic studies of infrared light reflected from the surface of Sedna reveal that it is probably unlike Pluto and Charon since Sedna’s surface does not display evidence for a large amount ...

Near-infrared spectroscopy, known as NIR spectroscopy or NIRS, is a long-established analytical technique. For over 30 years, it has proven to be a fast and reliable method for measuring chemical and ...

Acoustic MXene plasmons detect weak molecular fingerprints in nanometer-thick films while extending infrared sensing into the short-wave infrared.
