This article looks at the use of Raman and XRF spectroscopies to investigate the different deterioration processes caused by marine aerosols. These techniques can detect the decay compounds and the original composition of the different materials from historical buildings close to the sea, which can then be used to explain the reactions that take place on them. This helps in the development of remedial actions and preventive conservation strategies for historical buildings.
Entries for the IRDG Chalmers and Dent Student Travel Award for a PhD to present their research at the SciX meeting.
The Eagle Raman-S spectrometer platform from Ibsen Photonics is designed for OEM integration into weak intensity Raman solutions at 785 nm or 830 nm excitation.
Renishaw have added Bruker’s Dimension Icon atomic force microscope to the range of instruments supported by their inVia confocal Raman microscope.
As you will have noticed from this issue’s cover, we are making a colourful start to 2016. In the first article on “The analytical niche for Raman spectroscopy in biological pigment research”, Daniel Thomas and Cushla McGoverin suggest that Raman spectroscopy may have a particularly valuable role in pigment biology research. Pigments are almost universal in biology and are the basis of much of what we find attractive in flowers, birds and sea life, such as the fan corals on the cover. The authors show how Raman spectroscopy can be used to quickly confirm the presence of a pigment as well as providing more detailed knowledge about unknown pigments.
A technique to combine the ultra-sensitivity of surface enhanced Raman scattering (SERS) with a slippery surface invented by researchers at Pennsylvania State University, University Park, PA, USA, will make it feasible to detect single molecules of a number of chemical and biological species from gaseous, liquid or solid samples.
This product focus is on Molecular Spectroscopy.
Horiba Scientific’s ParticleFinder offers a user friendly tool for automated location, characterisation and Raman analysis of particles.
Laser Detect Systems is introducing the new edition of their B-SCAN—a Bottled Liquid Scanner.
The new TacPac accessory can be used with SERS consumables to identify street heroin.
Raman, FT-IR and ED XRF discover interesting detail of the dying in the 19th century, and maybe about trade links between Europe and Australia.
ST Japan-Europe has released a new collection of gemstone Raman spectra.
In the Tony Davies Column, Tony looks at “Raman imaging of difficult surfaces”. He looks at a number of different approaches to dealing with uneven samples, as well as reviewing instrumental improvements that have made Raman imaging a viable analytical and diagnostic tool.
Scientists at EPFL have shown how a light-induced force can amplify the sensitivity and resolution of SERS for the study of single molecules.
A team of researchers has demonstrated a new type of imaging system based on Raman spectroscopy that reveals the chemical composition of living tissue for medical diagnostics and cellular studies.
A report on the 12th Confocal Raman Imaging Symposium held in Ulm, Germany, September 2015, which covered a fascinating range of applications of the technique.
Using Raman spectroscopy and statistical analysis, an international group of scientists has succeeded in taking nanoscale measurements of the strain present at each pixel on the surface of graphene. The researchers also obtained a high-resolution view of the chemical properties of the graphene surface.
Kidney stones rank among the most common illnesses. Their recurrence may be prevented with the right post-operative care. However, for this to be effective, the composition of the stones needs to be known. Fraunhofer researchers are developing a Raman spectroscopy based system for rapid analysis of urinary stones immediately after the surgical procedure.
The new and improved S11850-1106 and S11851-1106 back-thinned CCD linear image sensors from Hamamatsu Photonics have improved etaloning characteristics and high sensitivity designed for spectrometry applications.
