Scientists at Oxford University are developing a new Doppler Global Velocimetry (DGV) technique that will enable three-dimensional fluid velocity fields to be imaged reliably and accurately.
Over the last twenty years, a number of techniques have been explored to enable clear imaging of fluid flows, with the most advantageous being those that are non-intrusive. To date, one of the most important techniques has been particle image velocimetry (PIV). However, there is a major disadvantage with using PIV because considerable off-line processing is necessary to deconvolve the double image into a velocimetry field and three-dimensional information is difficult to retrieve.
In order to improve this technique, researchers in the Department of Engineering Science at Oxford University have developed the Doppler Global Velocimetry (DGV) technique that enables three-dimensional imaging of fast fluid flows in both an efficient and reliable manner.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
