Local Study of Lithiation and Degradation Paths in LiMn2O4 Battery Cathodes: Confocal Raman Microscopy Approach

open access: yesBatteries, 2018
Lithium manganese-based cathodes are widely used in rechargeable batteries due to their low cost, safety, and ecological stability. On the other hand, fast capacity fade occurs in LiMn2O4 mainly because of the induced manganese dissolution and formation ...

Limit of Detection of Raman Spectroscopy Using Polystyrene Particles from 25 to 1000 nm in Aqueous Suspensions

open access: yesbioRxiv
Raman spectroscopy is an analytical method capable of detecting various microorganisms and small particles. Here, we used 25-1000 nm polystyrene particles in aqueous suspensions, which are comparable in size to viral particles and viral aggregates, to ...

Looking behind the scenes: Raman spectroscopy of top-gated epitaxial graphene through the substrate

open access: yesNew Journal of Physics, 2013
Raman spectroscopy is frequently used to study the properties of epitaxial graphene grown on silicon carbide (SiC). In this work, we present a confocal micro-Raman study of epitaxial graphene on SiC(0001) in top-down geometry, i.e.

Characterization of Hydrous Mineral Inclusions in Ruby and Sapphire by Infrared Spectroscopy and Microscopic Confocal Laser Raman Spectroscopy

open access: yesYankuang ceshi, 2019
BACKGROUND There are water molecules and hydrous mineral inclusions in natural ruby and sapphire. The hydrous minerals disappear easily after heat treatment, which causes the physical and chemical properties of ruby and sapphire to change.

Detection of nontoxic BoNT/A levels in post-facial Botox injection breastmilk

open access: yesFrontiers in Drug Safety and Regulation
The use of cosmetic Botox (BoNT/A) has become increasingly prevalent among women, even during the post-pregnancy breastfeeding period. However, there is currently a limited understanding of the extent Botox enters breastmilk and its potential effect on ...
