Journal Highlight: Structure of silk by Raman spectromicroscopy: From the spinning glands to the fibers

Date: Apr 2, 2012

Author:

This review describes recent advances in the study of the structure of silk by Raman spectromicroscopy, with particular emphasis on the spider dragline and silkworm cocoon threads, other fibers spun by orb-weaving spiders, the spinning dope contained in their silk glands and the effect of mechanical deformation.

Graphene: It runs right through a river?

Date: Apr 1, 2012

Author: David Bradley

A research team in Japan has synthesized the "wonder material" graphene by reducing graphene oxide using microorganisms extracted from a local river. Analysis by Raman spectroscopy verifies the chemistry of the graphene flakes.

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.

Journal Highlight: Forensic examination of multilayer white paint by lateral scanning Raman spectroscopy

Date: Feb 6, 2012

Author:

Lateral scanning Raman spectroscopy has been used to chemically map the cross-sections of multilayer white paint chips, allowing the different layers to be delineated on the basis of their spectral features.

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.

Journal Highlight: Membrane composition of jetted lipid vesicles: a Raman spectroscopy study

Date: Jan 9, 2012

Author:

The chemical composition of membranes of giant unilamellar phospholipid vesicles prepared by microfluidic jetting was determined using Raman scattering spectroscopy, revealing differences from vesicles prepared by other methods.

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.

Journal Highlight: Analysis of confiscated fireworks using Raman spectroscopy assisted with SEM-EDS and FTIR

Date: Dec 5, 2011

Author:

A forensic analysis of several samples of pyrotechnic artefacts by Raman spectroscopy assisted by SEM-EDS and FTIR spectroscopy revealed many components including several nitrates, ammonium perchlorate, nitrocellulose, metallic titanium particles and shellac.

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).

Forensic science: CSI Raman

Date: Nov 1, 2011

Author: David Bradley

Raman spectroscopy and an advanced statistical analysis have now been added to the arsenal of techniques available to law enforcement scientists allowing them to quickly and accurately identify traces of vaginal fluid at a crime scene.
