Quantitative Analysis of Chlorogenic Acid during Coffee Roasting via Raman Spectroscopy

open access: yesChemosensors
Tracking coffee roasting at an industrial scale for quality control is challenging. Bean color is a practical gauge for monitoring and regulating the process but only occurs before and after the process.

In situ Raman spectroscopic quantification of CH4–CO2 mixture: application to fluid inclusions hosted in quartz veins from the Longmaxi Formation shales in Sichuan Basin, southwestern China

open access: yesPetroleum Science, 2019
We re-evaluate the Raman spectroscopic quantification of the molar ratio and pressure for CH4–CO2 mixtures. Firstly, the Raman quantification factors of CH4 and CO2 increase with rising pressure at room temperature, indicating that Raman quantification ...

Understanding first order Raman spectra of boron carbides across the whole stoichiometry range

open access: yes, 2021
Boron carbide, a lightweight, high temperature material, has various applications as a structural material and as a neutron absorber. The large solubility range of carbon inboron, between $sim$ 9 % and 20 %, has been theoretically explained by some of us by the thermodynamical stability of three icosahedral phases at low temperature, with respective ...

High-resolution BOES Spectroscopy of Raman-scattered He iiλ6545 in Young Planetary Nebulae

open access: yesThe Astrophysical Journal
Young planetary nebulae (PNe) are characterized by their hot central stars and the presence of abundant neutral and molecular components, which result from significant mass loss during the asymptotic giant branch phase of stellar evolution. Far-UV He  ii
