Raman Spectroscopic Analysis and In Situ Heating Experiments on Adranosite Minerals

open access: yesJournal of Raman Spectroscopy, EarlyView.
This study provides the first detailed Raman spectroscopic characterization of rare ammonium sulfates adranosite, iron‐rich adranosite, and adranosite‐(Fe) from volcanic and coal‐fire environments. Distinct spectral features reveal compositional differences and structural effects of Fe substitution.

Measurement of Lateral Resolution in Confocal Raman Spectroscopy Using Indium Arsenide Nanowires

open access: yesJournal of Raman Spectroscopy, EarlyView.
Lateral resolution is a key performance parameter for confocal Raman spectroscopy. We propose a protocol using an indium arsenide nanowire reference sample to quantitatively measure the resolution. The suitability of the method has been demonstrated through an international comparison with 15 participants. ABSTRACT Lateral resolution is a key figure of

Exploring Raman Spectroscopy as a Detection Tool for Cardiovascular Diseases and Diabetes Mellitus in Fingernails

open access: yesJournal of Raman Spectroscopy, EarlyView.
Endogenous constituents vary between fingernails of healthy, cardiovascular and diabetic participants. Raman spectroscopy yields a biochemical fingerprint of key endogenous constituents and disease‐related biomarkers. Combined with machine learning algorithms, Raman spectroscopy can classify healthy, cardiovascular and diabetic based on their Raman ...

Nano‐Raman Spectroscopy of Tellurium Nanowires

open access: yesJournal of Raman Spectroscopy, EarlyView.
Nano‐Raman evidences a diameter dependence of the peak position, among different tellurium nanowires and along the single species. ABSTRACT Tellurium‐based nanowires are interesting structures for applications in low‐dimensional electronics. This work investigates the vibrational dynamics of trigonal tellurium (t‐Te) nanowires through tip‐enhanced ...
