A review reports on developments and prospects in the field of atomic and molecular broadband spectroscopy with frequency combs.
While spectroscopic measurements are normally averaged over myriad molecules, a new method developed by researchers at the Technical University of Munich provides precise information about the interaction of individual molecules with their environment.
2D laser-induced breakdown spectroscopy imaging of shell growth rings is revealing previously hidden data of marine climate change.
A small group of plants known as “resurrection plants” can survive months or even years without water. NIR spectroscopy and aquaphotomics have made a significant step forward in understanding how they do it.
The XMaS beamline at the European Synchrotron Radiation Facility is to undergo a major upgrade over the next 18 months.
Researchers in Switzerland and Russia have developed a miniature frequency comb (1 cm3) that can be mass produced.
Physicists from the University of Basel have developed a new method to examine the elasticity and binding properties of DNA molecules on a surface at extremely low temperatures. With a combination of cryo-force spectroscopy and computer simulations, they were able to show that DNA molecules behave like a chain of small coil springs.
imec have developed an on-chip solution for Raman spectroscopy that could be used to manufacture high-performance, handheld Raman devices; perhaps even in smartphones.
Plastics recycling is complicated by the need to recycle similar plastics together. The presence of flame retardants in plastics also needs to be identified, and NIR hyperspectral imaging can do this.
A new sensor fusion technique based on X-ray and 3D imaging promises improvements to the 3D modelling of mineral resources and more efficient sorting of precious metals.
When assessing a burn patient, doctors use factors such as the depth and size of the burn, as well as the time required for re-epithelialisation. Another, possibly more accurate way to classify burn severity has been developed through analysing the proteome of blister fluid by mass spectrometry.
Researchers at MIT have developed a way to dramatically enhance the sensitivity of nuclear magnetic resonance spectroscopy using pulsed dynamic nuclear polarisation.
Scientists from the Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy have carried out the first attosecond transient absorption spectroscopy (ATAS) experiment on a polyatomic molecule.
Research at NPL has revealed unusual qualities in light with future applications for synchronously pumped optical frequency comb generation and resonator-based sensor technologies.
A range of components for miniaturised mid-IR gas sensors from source to detector have been developed by the Horizon 2020 project MIREGAS.
Pairs of negatively charged phosphate groups and positive magnesium ions represent a key structural feature of DNA and RNA embedded in water. Vibrations of phosphate groups via 2D-IR spectroscopy have now been established as selective probes of such contact pairs and allow for a mapping of interactions and structure on the ultrafast time scales of molecular dynamics.
EU grant worth EUR 2 million for the development of a new approach in optical spectroscopy of the superheavy elements.
A new method to measure circular dichroism in real-time (1 ps to 1 ns) allows measurements into the deep UV.
A miniature food scanner based on NIR spectroscopy will allow consumers and supermarket operators to determine the ripeness and shelf life of produce and display the results via an app.
Timegate Instruments, manufacturer of time-gated Raman spectroscopy instruments, has raised funding of 2.6 M€ for product and business development.
