PiFM and PiF-IR are the next generation of infrared spectroscopy techniques. PiFM brought a major shift to atomic force microscopy by adding chemical mapping capabilities. PiF-IR, its sister technique ...

Near infrared spectroscopy (NIRS) has emerged as a transformative, non‐destructive analytical tool for evaluating the properties of wood, providing rapid assessments of chemical and physical ...

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 ...

Vibrational spectroscopy is a high-performance analytical technique commonly used in chemistry, materials science, biology, and environmental research. Infrared spectroscopy (IR) is the most ...

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, ...

Photothermal AFM-IR, commonly referred to as AFM-IR, is an analytical technique used to understand the chemistry of a material at the nanoscale. It combines the nanoscale spatial resolution of atomic ...

This article introduces the differences and similarities between Raman and infrared spectroscopy for identifying unknown materials and monitoring reactions. While the techniques are pretty similar, ...

Photothermal AFM-IR, or AFM-IR, is an analytical method used for chemical identification in a materials sample at the nanoscale. AFM-IR incorporates both the nanoscale spatial resolution of atomic ...
