Non-equilibrium atmospheric-pressure plasmas have recently become a topical area of
research owing to their diverse applications in health care and medicine, environmental …

The detection and measurement of gas concentrations using the characteristic optical
absorption of the gas species is important for both understanding and monitoring a variety of …

A detailed review on the development of quartz-enhanced photoacoustic sensors (QEPAS)
for the sensitive and selective quantification of molecular trace gas species with resolved …

Optical spectroscopy has a broad scientific basis in chemistry, physics, and material science,
with diverse applications in medicine, pharmaceuticals, agriculture, and environmental …

The collisions between two oxygen molecules give rise to O4 absorption in the Earth
atmosphere. O4 absorption is relevant to atmospheric transmission and Earth's radiation …

The sensitivity of molecular fingerprinting is dramatically improved when the absorbing
sample is placed in a high-finesse optical cavity, because the effective path length is …

This review summarizes the state of the art of plasma diagnostics on atmospheric pressure
plasmas formed at characteristic length scales of approximately 1 mm or smaller and …

The limit of detection (LOD) and the sensitivity of a chemical sensor are defined using
IUPAC guidelines. The LOD from simulated and experimental data is calculated from a …

Atmospheric brown carbon (BrC) is an important contributor to the radiative forcing of climate
by organic aerosols. Because of the molecular diversity of BrC compounds and their …

Cavity ring-down spectroscopy (CRDS), first pioneered in 1988 by O'Keefe and Deacon, 1
has evolved into a newgeneration, precision spectroscopy in recent years and subsequently …
