For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food ...

The evidence indicates that non-invasive monitoring (near-infrared spectroscopy; NIRS) of oxygen in brain tissue likely does not reduce death rates or short-term brain problems for very premature ...

Resting on a fingertip, this miniature sensor replaces bulky laboratory equipment by using photon-trapping surface nanostructures and artificial intelligence (AI) to accurately analyze disease, check ...

Inks and paints are everywhere in the world around us. As well as for writing and printing, these materials are also used for protection against the elements and aesthetic reasons. These substances ...

Near infrared optical coherence tomography (NIR OCT) is a non-contact, noninvasive imaging technique that uses near infrared light to generate cross-sectional images from the light scattered back by a ...

This paper explores the differences and similarities between Raman and infrared spectroscopy in regard to unknown material identification and reaction monitoring. While these techniques share ...

Prepregs are reinforcement materials that have been pre-impregnated with either thermoplastic or thermoset resins. They are used in high-performance applications where mechanical properties and low ...

Plasmonic nanogap confinement extends sum frequency vibrational spectroscopy to the nanoscale, enabling direct imaging of ...
