Ultraviolet spectroscopy of pressurized and supercritical carbon dioxide [PDF]

open access: yesCommunications Chemistry, 2021
CO2 is prominent in the Earth’s and exoplanetary atmospheres, but its excited state photochemistry is not yet fully understood. Here the authors identify gradual quenching of the diffuse vibrational structure in supercritical CO2 electronic spectra under

Ultraviolet intracavity laser absorption spectroscopy [PDF]

open access: yesSensors and Actuators B: Chemical, 2023
Intracavity Laser Absorption Spectroscopy (ICAS) provides an excellent solution for ultrasensitive, multiplexed, quantitative detection of reactive species, but has traditionally been limited to the visible and infrared spectral regions by the ...

Free-running ultraviolet dual comb spectroscopy enabling absolute electronic fingerprinting [PDF]

open access: yesPhotoniX
Ultraviolet (UV) spectroscopy reveals electronic transitions in matter that underpin atmospheric photochemistry and molecular dynamics. While dual-comb spectroscopy (DCS) has revolutionized precision measurements in the infrared region and expanded to ...

UV-activated assisted electrochemical process for mine water deep mineralization and resource recovery [PDF]

open access: yesNature Communications
High-salinity mine water generated during membrane concentration of mine water contains structurally stable complex organic matter that resists removal and mineralization by conventional advanced oxidation processes, ultimately producing low-value by ...

Broadband near-ultraviolet dual comb spectroscopy

open access: yesOptica
The highly energetic photons of ultraviolet light drive electronic and rovibronic transitions in all molecular species. This radiation is thus a prime tool for strongly selective spectroscopic fingerprinting and real-time environmental monitoring if ...

Ultraviolet Raman spectroscopy of catalysts and other solids

open access: yesJournal of Vacuum Science and Technology A: Vacuum, Surfaces and Films, 1997
Resonance Raman spectroscopy measurements, which utilize ultraviolet (UV) excitation, appear to be very useful for the study of catalysts and other solids, which produce strong fluorescence that makes conventional Raman spectroscopy very difficult.

Ozone Detection via Deep-Ultraviolet Cavity-Enhanced Absorption Spectroscopy with a Laser Driven Light Source

open access: yesSensors, 2023
We present a novel sensing approach for ambient ozone detection based on deep-ultraviolet (DUV) cavity-enhanced absorption spectroscopy (CEAS) using a laser driven light source (LDLS).

Early-time Ultraviolet and Optical Hubble Space Telescope Spectroscopy of the Type II Supernova 2022wsp

open access: yesThe Astrophysical Journal Letters, 2023
We report early-time ultraviolet (UV) and optical spectroscopy of the young, nearby Type II supernova (SN) 2022wsp obtained by the Hubble Space Telescope (HST)/STIS at about 10 and 20 days after the explosion.

A Turbidity-Compensation Method for Nitrate Measurement Based on Ultraviolet Difference Spectroscopy

open access: yesMolecules, 2022
To solve the problem that turbidity in water has a significant effect on the spectra of nitrate and reduces the accuracy of nitrate detection, a turbidity-compensation method for nitrate measurement based on ultraviolet difference spectra is proposed ...

Effects of Mesona chinensis Benth Polysaccharide on the Physicochemical Properties and Structural Characteristics of Myosin [PDF]

open access: yesShipin Kexue, 2023
The effects of different concentrations (0–0.10 mg/mL) of Mesona chinensis Benth polysaccharide (MCP) on the physicochemical properties (potential, particle size, surface hydrophobicity, and sulfhydryl groups), structural properties (determined by ...
