Broadband transmission EPR spectroscopy. [PDF]

PLoS ONE, 2013
EPR spectroscopy employs a resonator operating at a single microwave frequency and phase-sensitive detection using modulation of the magnetic field. The X-band spectrometer is the general standard with a frequency in the 9-10 GHz range.

Assessment and prediction of tablet properties using transmission and backscattering Raman spectroscopy and transmission NIR spectroscopy

Asian Journal of Pharmaceutical Sciences, 2016
This study investigated whether Raman and Near Infrared (NIR) spectroscopy could predict tablet properties. Granules were produced on a continuous line by varying granulation parameters. Tableting process parameters were adjusted to obtain uniform tablet

Unraveling Band‐Tail Effects on Temperature‐Dependent Emission in GaAsBi via Photoluminescence [PDF]

Advanced Science
The effect of Bi on the emission temperature sensitivity of GaAsBi remains a topic of debate, which hinders the design of optoelectronic devices. Band‐tail states, which are critical for GaAsBi performance, are suspected to drive the discrepancy, but ...

Exoplanet transmission spectroscopy using KMOS [PDF]

Monthly Notices of the Royal Astronomical Society, 2015
KMOS (K-Band Multi Object Spectrograph) is a novel integral field spectrograph installed in the VLT's ANTU unit. The instrument offers an ability to observe 24 2.8"$\times$2.8" sub-fields positionable within a 7.2' patrol field, each sub-field producing a spectrum with a 14$\times$14-pixel spatial resolution.

ESPRESSO high-resolution transmission spectroscopy of WASP-76 b [PDF]

Astronomy & Astrophysics, 2021
Aims. We report on ESPRESSO high-resolution transmission spectroscopic observations of two primary transits of the highly irradiated, ultra-hot Jupiter-sized planet, WASP-76b. We investigated the presence of several key atomic and molecular features of interest that may reveal the atmospheric properties of the planet. Methods.
