Chiral sum frequency generation spectroscopy is a comparatively new technique involving the interaction of two beams of different frequencies. It is providing important information about how water interacts with biological systems such as DNA.
Scientists at the University of Sheffield have used NMR spectroscopy to examine the molecules in live sperm, and early data suggests it could discriminate between populations of good and poor sperm. Thus, it might be useful to improve diagnosis of sperm problems because it is non-destructive, so the sperm examined could be used in fertility treatments after analysis.
Ultraviolet spectropolarimetry has produced some unexpected results from analysis of solar radiation, showing important information on aspects of the Sun’s magnetic field.
A Japanese research group has developed new techniques to perform analysis and imaging of chemical elements by taking images of a target material using an ordinary, visible-light digital camera with a slight modification, and obtaining X-ray spectra from processed images.
Spectroscopy imaging on the nanoscale is being helped by a new fibre nanoimprinting process.
A group of scientists from EAWAG, the Swiss Federal Institute of Aquatic Science and Technology, have developed a portable mass spectrometer allowing on-site measurements, and a spin-off has been created to commercialise the new system.
A study by the UPV/EHU-University of the Basque Country is using a portable device based on Raman spectroscopy to monitor the ripeness of tomato fruits.
Analytik has been appointed as exclusive distributors for Nanophoton, Japanese manufacturers of benchtop Raman imaging systems for both industrial and research laboratories.
Enhancements of photoacoustic spectroscopy enable analysis of single melanoma cells and improved detection of melanoma.
Professor Andrew Orr-Ewing, known for his work on ultrafast laser spectroscopy, has been elected as Fellow of the Royal Society.
A new optical spectroscopy technique developed by researchers at Lawrence Livermore National Lab promises to improve accuracy and lower costs of real-time assessment of kidney function.
Stimulated Raman projection microscopy and tomography using a special type of laser beam to penetrate deep into tissue might lead to technologies that eliminate the need to draw blood for analyses including drug testing and early detection of diseases such as cancer and diabetes.
A research team at Osaka University has developed an approach to increase the resolution of multichannel spectrometers.
Researchers at Northwestern University have created a new method (gradient-assisted multi-dimensional electronic Raman spectroscopy) to extract the static and dynamic structure of complex chemical systems. This new method uses four spectral dimensions to resolve structure to reveal hidden features of molecular structure.
The study of jet disintegration focuses on fuel breakup and mixing within the combustion chamber of propulsion devices. A team of researchers at the University of Florida have applied spectroscopic diagnostics techniques to learn more about the fundamentals of sub- and supercritical jet disintegration.
Titanium dioxide (TiO2) is one of the most promising materials for photovoltaics and photocatalysis nowadays. This material appears in different crystalline forms, but the most attractive one for applications is “anatase”. EPFL scientists have now shed light onto the problem by a combination of steady-state and ultrafast spectroscopic techniques, as well as theoretical calculations.
Electron movements in a transient state of a reaction important in biochemical and optoelectronic processes have been captured and, for the first time, directly characterised using ultrafast X-ray spectroscopy at the Department of Energy’s Lawrence Berkeley National Laboratory.
TOPTICA Photonics and Menlo Systems have entered into a license agreement for the use of patented frequency comb technology.
The WADI project is using hyperspectral, multispectral and thermographic infrared imaging to detect soil moisture and those leaks from water mains in rural areas.
Quantum mechanics dictates how particles and forces interact, and thus how atoms and molecules work, for example, what happens when a molecule goes from a higher-energy state to a lower-energy one. But beyond the simplest molecules, the details become very complex. Now, a Pixel-Imaging Mass Spectrometry camera and a femtosecond vacuum ultraviolet light source are showing how does quantum mechanics work in larger, more complex systems.
