Optical spectroscopy techniques are used in physics, astronomy, chemistry, biology, and associated research fields.

Functional near-infrared spectroscopy (fNIRS) has been increasingly applied in poststroke research. The accumulated evidence in this area warrants a comprehensive review systematically investigating ...

Mid-infrared (IR) spectroscopy has the advantage of being fast and nondestructive for mineral identification and geological analysis. Mineral anomalies in fault zones are geological markers for fault ...

Best electric bikes available today Best electric road bikes The best electric bikes are almost indistinguishable from pedal-powered bikes nowadays, utilising high-quality components and clever ...

Near-infrared spectroscopy articles from across Nature Portfolio Near-infrared spectroscopy is a form of non-invasive imaging that applies near-infrared radiation (wavelengths 780 nm to 3,000 nm ...

IDDF2025-ABS-0117 Highly sensitive near-infrared fluorescent probe for detecting necrotizing enterocolitis by hypochlorous acid real-time imaging ...

Acetic acid exists as syn- and anti-isomers in a low-temperature rare-gas matrix. However, in aprotic acetonitrile, its IR spectrum in the C═O stretch region exhibits a multiple-band feature, which is ...
