A coherent, nanoscale beam of X-rays from a synchrotron source have been used to map chemical reactions happening inside lithium-ion batteries in three dimensions at the nanoscale.
Infrared laser techniques have been used to study methane scattering on a nickel surface for the first time with full quantum-state resolution.
Raman, infrared, x-ray photoelectron and ultraviolet/visible spectroscopies are being used at the University of Liverpool to help develop better energy storage devices.
Nuclear resonant vibrational spectroscopy, a new X-ray spectroscopy technique has been used to study enzymes that can produce hydrogen gas, the understanding of their reactions could be important in developing a clean-fuel economy powered by hydrogen.
A new method, using deep-ultraviolet continuum pulses, has been developed to efficiently measure electron transfer in dye-sensitised, transition-metal oxide photovoltaics.
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.
X-ray images and XANES reveal battery materials’ chemical reactions in five dimensions: 3D space plus time and energy.
Edinburgh Instruments have installated one of their fluorescence spectroscopy systems at the brand new Vidyasirimedhi Institute of Science and Technology (VISTEC) in Thailand.
