diamond-aerialUnderstanding the crystal chemistry of Nickel (Ni), in particular how the element is bonded to its surrounding elements, can improve its extraction process, making it greener and increasing the yield. Scientists from Diamond (the UK’s national synchrotron facility), in collaboration with mineralogists from the University of Barcelona, Spain, have combined measurements on the Microfocus Spectroscopy beamline (I18) and Raman spectroscopy to elucidate the chemistry and local environment of Ni in a Mn-oxyhydroxyde aggregate.

The first group of graduates of a new European Master's degree received their diplomas at the European Commission's Joint Research Centre (JRC) in Geel, Belgium. The degree, “Measurement Science in Chemistry”, was based on training initiatives developed by the JRC's Institute for Reference Materials and Measurements (IRMM).

Hairbrush for functional NIR imaging of brain

fNIR-hairbrush1-sOne of the main techniques for measuring and monitoring mental activity, functional near infrared spectroscopy (fNIRS), can often be impaired because a person’s hair gets in the way. A team of researchers at the University of Texas at Dallas and the University of Texas at Arlington have developed a “brush optrode”, which provides increased sensitivity with fibre tips designed to thread through hair to enhance scalp contact.

optical-frequency-comb-sScientists at JILA (a joint operation of the National Institute of Standards and Technology and the University of Colorado at Boulder) and collaborators have demonstrated an improved laser-based "molecular fingerprinting" technique that picks out traces of key hydrogen-containing and other molecules from a billion other particles in a gas in just 30 seconds or less—performance suitable for breathalysers for diagnosing disease, measuring trace gases in the atmosphere, detecting security threats and other applications.

Faster CARS has potential for cell diagnostics

Faster CARS has Potential for Cell DiagnosticsA paper by researchers at the National Institute of Standards and Technology (NIST) may breathe new life into the use of a powerful—but tricky—diagnostic technique for cell biology. The paper in the Biophysical Journal, demonstrates that with improved hardware and better signal processing, an enhancement to Raman spectroscopy, broadband coherent anti-Stokes Raman scattering (B-CARS), can quickly deliver detailed molecular maps of the contents of cells without damaging them. Earlier studies have suggested that to be useful, the technique would need power levels too high for cells.
