A research team has fabricated a subwavelength grating from an epitaxial molybdenum diselenide (MoSe2) layer roughly 42 ...

To investigate how melanin affects the accuracy of near-infrared spectroscopy (NIRS) measurements, researchers correlated the melanin levels of 35 adults with a diverse range of skin tones, measured ...

Researchers have successfully demonstrated a spectrometer that is orders of magnitude smaller than current technologies and can accurately measure wavelengths of light from ultraviolet to the ...

A near-IR module intended to assist with personal health monitoring is said to be the world's first consumer spectroscopy module for smartphones. Unveiled at Qualcomm's Snapdragon Summit 2023 and ...

Photothermal AFM-IR combines atomic force microscopy and infrared spectroscopy to reveal chemical heterogeneity and ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

Sunlight contains an electromagnetic spectrum (special waves such as the kind in x-rays that travel through emptiness or a vacuum) of light that stretches from very short gamma rays to very long radio ...
