Organic compounds are widespread pollutants in wastewater, causing significant risks for
living organisms. In terms of advanced oxidation processes, photocatalysis is known as an …

This article reviews the basic principles of frequency-domain near-infrared spectroscopy (FD-
NIRS), which relies on intensity-modulated light sources and phase-sensitive optical …

Near-infrared spectroscopy (NIRS) is an optical technique that can measure brain tissue
oxygenation and haemodynamics in real-time and at the patient bedside allowing medical …

Besides passive recording of brain electric or magnetic activity, also non-ionizing
electromagnetic or optical radiation can be used for real-time brain imaging. Here, changes …

Significance Advances in electronics have allowed the recent development of compact, high
channel count time domain functional near-infrared spectroscopy (TD-fNIRS) systems …

Background Cardiovascular disease (CVD) is associated with impairments in microvascular
responsiveness. Therefore, reliably assessing microvascular function is clinically relevant …

Cerebral and somatic near-infrared spectroscopy monitors are commonly used to detect
tissue oxygenation in various circumstances. This form of monitoring is based on tissue …

In the last three decades, the development and steady improvement of various optical
technologies at the near-infrared region of the electromagnetic spectrum has inspired a …

Currently, there is great interest in making neuroimaging widely accessible and thus
expanding the sampling population for better understanding and preventing diseases. The …
