NEWS: the near-infrared Echelle for wideband spectroscopy [PDF]

open access: yes, 2016
We present an updated optical and mechanical design of NEWS: the Near-infrared Echelle for Wide-band Spectroscopy (formerly called HiJaK: the High-resolution J, H and K spectrometer), a compact, high-resolution, near-infrared spectrometer for 5-meter ...

Near infrared spectroscopy for fibre based gas detection [PDF]

open access: yes, 2010
Gas sensing systems based on fibre optic linked near infra red absorption cells are potentially a flexible and effective tool for monitoring accumulations of hazardous and noxious gases in enclosed areas such as tunnels and mines.

Original plant traceability of Dendrobium species using multi-spectroscopy fusion and mathematical models [PDF]

open access: yesRoyal Society Open Science, 2019
Dendrobium is the largest genus of orchids most of which have excellent medicinal properties. Fresh stems of some species have been consumed in daily life by Asians for thousands of years.

The surface composition of asteroid 162173 Ryugu from Hayabusa2 near-infrared spectroscopy

open access: yesScience, 2019
Hayabusa2 at the asteroid Ryugu Asteroids fall to Earth in the form of meteorites, but these provide little information about their origins. The Japanese mission Hayabusa2 is designed to collect samples directly from the surface of an asteroid and return

Evidence that large vessels do affect near infrared spectroscopy

open access: yesScientific Reports, 2022
The influence of large vessels on near infrared spectroscopy (NIRS) measurement is generally considered negligible. Aim of this study is to test the hypothesis that changes in the vessel size, by varying the amount of absorbed NIR light, could profoundly

g-C3N4 Modified by meso-Tetrahydroxyphenylchlorin for Photocatalytic Hydrogen Evolution Under Visible/Near-Infrared Light

open access: yesFrontiers in Chemistry, 2020
A new photocatalyst denoted as mTHPC/pCN was prepared by modifying protonated graphitic carbon nitride (pCN) by meso-tetrahydroxyphenylchlorin (mTHPC). Relevant samples were characterized via various methods including zeta potential measurements, X-ray ...
