What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

Near-infrared spectroscopy (NIRS) is a noninvasive method used to monitor changes in hemoglobin concentration and oxygen levels in the body. This technique involves passing near-infrared light, ...

Researchers used theoretical calculations assessing electron orbital symmetry to synthesize new molecule designed to be both transparent and colorless while absorbing near-infrared light. This ...

A research group led by Associate Professor Masahito Murai of the Graduate School of Science and Professor Shigehiro Yamaguchi of the Functional Organic Materials Laboratory has successfully developed ...

Researchers at the Indian Institute of Science (IISc) have fabricated a device to increase or "up-convert" the frequency of short infrared light to the visible range. Up-conversion of light has ...
