Raman @ spectroscopyNOW

The Raman spectroscopy channel covers research into all aspects of this non-destructive technique including surface-enhanced Raman spectroscopy (SERS), and related applications such as drug detection, forensics, environmental analysis, art and archaeology research, food quality analysis, homeland security, cancer research and material science.   

Monthly Highlight

Last Month's Most Accessed Feature: Time for resolution: Single molecule

For the first time, chemists have succeeded in measuring the vibrational movements of a single molecule with time resolution on the femtosecond scale using time-resolved coherent anti-Stokes Raman scattering.

Speciation Analysis of Manganese Dissolution in
Li-Ion Batteries

Manganese-based LIBs are environmentally friendly, have a good safety record, and can be produced at a lower cost than other metal-based LIBs; however, they have a shorter lifetime. One reported cause of lifetime loss is the dissolution of manganese from the cathode into the electrolyte during cycling. This presentation will discuss the analysis of cycled anode material and the separation of different degradation products.

Micro-Raman spectroscopy combined with image analysis can be a potentially useful tool for rapid and label-free identification of normal sperm cell by providing both morphological and biochemical information.

Diamond: Hanging by a nanothread

David Bradley

Oct 1, 2014

thumbnail image: Diamond Hanging by a nanothread

For the first time, scientists have made ultra-thin 'diamond nanothreads' with a unique structure that could be stiffer and stronger than known polymers and nanotubes. The team used a range of techniques including Raman spectroscopy, X-ray and neutron diffraction, nuclear magnetic resonance spectroscopy, transmission electron microscopy and first-principle calculations to analyse and characterise the materials

A pen-on-paper approach for making SERS substrates should bring the technique closer to the real world using ink cartridges fixed to a pen to create plasmonic sensors at will.
