Ultraviolet spectropolarimetry has produced some unexpected results from analysis of solar radiation, showing important information on aspects of the Sun’s magnetic field.
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.
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 WADI project is using hyperspectral, multispectral and thermographic infrared imaging to detect soil moisture and those leaks from water mains in rural areas.
Salmon is one of the most popular edible fish of all. Shops sell fish caught in the wild, but their main produce is salmon from breeding farms, the effluent from which can pollute rivers, lakes and oceans. German and Chilean scientists have used fluorescence measurements, high-resolution mass spectrometry and nuclear magnetic resonance spectroscopy to answer this question.
A chemist at the National Institute of Standards and Technology (NIST) has developed a portable version of his headspace method for recovering trace chemicals such as environmental pollutants and forensic evidence including secret graves and arson fire debris.
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.
A new study led by scientists at The Scripps Research Institute (TSRI) shows that gas chromatography mass spectrometry fundamentally alters the samples it analyses.
