Journal Highlight: Laser induced temperature effects in multi-walled carbon nanotubes probed by Raman spectroscopy

Date: Mar 5, 2012

Author:

The influence of continuous laser irradiation on as-prepared and oxidized multi-walled carbon nanotubes (MWCNTs) was studied by Raman scattering, allowing for the effects of impurities on the signals.

Material transparency: Water cannot see graphene

Date: Feb 1, 2012

Author: David Bradley

Raman spectroscopy has been used to investigate graphene, which might be considered the thinnest material known. The nanomaterial is not transparent to light, but water behaves as if it were not there.

Cleaning CARS: Cutting down on spectral noise pollution

Date: Jan 5, 2012

Author: David Bradley

Researchers at the University of Twente's MESA+ Institute for Nanotechnology and elsewhere have used a "reverse" approach to cleaning CARS, coherent anti-Stokes Raman spectroscopy, images that helps them eliminate background noise.

Lab on a bubble: SERS on spheres

Date: Dec 1, 2011

Author: David Bradley

A new class of materials for surface-enhanced Raman spectroscopy (SERS) consisting of hollow, buoyant silica microspheres coated with gold nanoparticles has been developed. These new materials allow for a novel type of molecular assay designated as a lab-on-a-bubble (LoB).
