Ultra-short X-ray laser pulses precisely surveyed for the first time
X-ray lasers are modern light sources from which scientists expect to obtain new knowledge about the structure and function of materials at the atomic level. The scientific value of an X-ray laser stands or falls on the quality of the ultra-short X-ray pulses it produces and which researchers use to illuminate their samples. An international team led by scientists from the Paul Scherer Institute, PSI, has now precisely measured these pulses
Distribution of soot particles in particulate filters of diesel vehicles seen for the first time
Diesel motor vehicles have to be equipped with soot particulate filters, so the harmful soot and ash cannot get into the environment. Whilst these operate according to appropriate standards, up until now, the details about the distribution of soot and ash inside these filters has been unknown. Now, thanks to the special examination techniques of the Paul Scherrer Institute [PSI], the actual filter loads have been seen for the first time.
Observation of a New Particle with a Mass of 125 GeV
In a joint seminar today at CERN and the ICHEP 2012 conference in Melbourne, researchers of the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC) presented their preliminary results on the search for the standard model (SM) Higgs boson in their data recorded up to June 2012.
Controversy clarified: Why two insulators together can transport electricity
How can two materials which do not conduct electricity create an electrically conducting layer when they are joined together? Since this effect was discovered in 2004, researchers have developed various hypotheses to answer this question. Now, an international team under the leadership of researchers at the Paul Scherrer Institute has probably settled the controversy.
