Raman spectroscopy is an important and powerful technique for analyzing the chemical
composition of biological or nonbiological samples in many fields. A serious challenge …

In this review, topic modeling—an unsupervised machine learning tool—is employed to
analyze research on pigments in cultural heritage published from 1999–2023. The review …

Fluorescent background is a major problem in recoding the Raman spectra of many
samples, which swamps or obscures the Raman signals. The background should be …

A novel Raman spectrometer is presented in a handheld format. The spectrometer utilizes a
temperature-controlled, distributed Bragg reflector diode laser, which allows the instrument …

Multi-excitation Raman spectroscopy filters out Raman signals from a fluorescent
background by sequentially using multiple excitation frequencies. The filtering method …

Herein, we present progress towards an analytical sensor for polycyclic aromatic
hydrocarbons (PAHs) using surface-enhanced Raman scattering (SERS) on partition layer …

The lack of appropriate cathodes is restraining the advances of Mg batteries. Crystalline
cathode materials suffer from sluggish reaction kinetics and low-capacity delivery. The finite …

Raman spectroscopy provides label-free biochemical information from tissue samples
without complicated sample preparation. The clinical capability of Raman spectroscopy has …

Laser instruments often suffer from the problem of baseline drift and random noise, which
greatly degrade spectral quality. In this article, we propose a variation model that combines …

Fast gating in Raman spectroscopy is used to reject the fluorescence contribution from the
sample and/or the substrate. Several techniques have been set up in the last few decades …
