Raman Imaging of Plant Cell Walls in Sections of Cucumis sativus

open access: yesPlants, 2018
Raman microspectra combine information on chemical composition of plant tissues with spatial information. The contributions from the building blocks of the cell walls in the Raman spectra of plant tissues can vary in the microscopic sub-structures of the

Raman Spectra Characteristics of Fluid Inclusion in the Shaanxi Formation of the Dingbian Area in the Ordos Basin

open access: yesYankuang ceshi, 2015
Raman Spectroscopy is an important means of non-destructive fluid inclusions analysis. Composition of fluid inclusions in quartz from the Shaanxi formation of the Dingbian area in the Ordos Basin was determined by the Raman technique.

Rapid Discrimination of Clinically Important Pathogens Through Machine Learning Analysis of Surface Enhanced Raman Spectra

open access: yesFrontiers in Microbiology, 2022
With its low-cost, label-free and non-destructive features, Raman spectroscopy is becoming an attractive technique with high potential to discriminate the causative agent of bacterial infections and bacterial infections per se. However, it is challenging

Rapid identification of pathogenic bacteria using Raman spectroscopy and deep learning

open access: yesNature Communications, 2019
The use of Raman spectroscopy for pathogen identification is hampered by the weak Raman signal and phenotypic diversity of bacterial cells. Here the authors generate an extensive dataset of bacterial Raman spectra and apply deep learning to identify ...

Trace Nickel Activated Biphasic Core‐CuOii/Shell‐CuOi Secondary Microspheres Enable Room Temperature Parts‐Per‐Trillion‐Level NO2 Detection

open access: yesAdvanced Engineering Materials, EarlyView.
An idea of designing novel sensors is proposed by creating appropriate Schottky barriers and vacancies between isomorphous Core‐CuOii/ Shell‐CuOi secondary microspheres and enhancing catalytic and spill‐over effects, and electronegativity via spontaneous biphasic separation, self‐assembly, and trace‐Ni‐doping.
