Cerebral blood flow is essential for normal brain function and often perturbed in neurological disease. If one shines a ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

Positron Annihilation Spectroscopy (PAS) is a highly sensitive, non-destructive method for probing atomic-scale imperfections in a broad spectrum of materials, from metals and ceramics to polymers and ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Light speckle fluctuations, a noninvasive proxy for cerebral blood flow index (CBFi), are quantified by diffuse correlation spectroscopy. However, this conventional technique provides marginal brain ...

The explosive growth of electric vehicles, renewable energy integration, and large-scale energy storage systems has placed ...

Definition:Raman Spectroscopy is a sophisticated analytical technique used to observe vibrational, rotational, and other low-frequency modes in a system. This material characterization technique ...

Photoemission spectroscopy (PES) is a powerful analytical technique used to study the electronic structure and chemical composition of materials. It is based on the photoelectric effect, where ...

In this interview conducted at Pittcon 2024 in San Diego, we spoke to Richard Crocombe about his journey in the field of spectroscopy, focusing on the development of portable spectrometers and their ...
