- New X-ray method uses scattering to visualize nanostructures
Both in materials science and in biomedical research it is important to be able to view minute nanostructures, for example in carbon-fiber materials and bones. A team from the Technical University ... - Structure of "concrete disease" solved
When bridges, dam walls and other structures made of concrete are streaked with dark cracks after a few decades, the culprit is AAR: the alkali-aggregate reaction. Also called the "concrete disease... - Spin-Echo-Spectroscopy will enable most accurate neutron measurement yet
Our universe consists of significantly more matter than existing theories are able to explain. This is one of the great puzzles of modern science. One way to clarify this discrepancy is via the neu... - A method developed for x-ray free-electron lasers should help researchers to decode biomolecules
Without proteins, our bodies wouldn't even work. These multifaceted transformation artists sit in every cell and control our bodily functions. One of the many examples is the so-called chemokine re...
- High resolution in tomography with hard X-rays
Tomography enables the interior of a vast range of objects to be depicted in 3D - from cellular structures to technical appliances. Researchers from the Paul Scherrer Institut (PSI) have now devise... - New insight into photosynthesis
The way that algae and plants respond to light has been reinterpreted based on results from experiments studying real-time structural changes in green algae. Under particular lighting conditions du...
- Particle formation in the atmosphere - further aspect unveiled
Natural and man-made amine emissions could influence the formation of particles in the atmosphere - and thus our climate. Thanks to new measuring methods with unprecedented accuracy, the formation ... - How Matter assembles: Tiny Magnets as a Model System
In the microscopic world, everything is in motion: atoms and molecules vibrate, proteins fold, even glass is a slow flowing liquid. And during each movement there are interactions between the small... - Observing engine oil beneath metal
Lubricating oil is essential for engines. Multi-disc clutches, like those found in motorcycles, are also lubricated and cooled with oil. The oil pump has to be driven by the engine at the same time...
- Ultra-short X-ray laser pulses precisely surveyed for the first time
X-ray lasers belong to a modern generation of light sources from which scientists in widely different disciplines expect to obtain new knowledge about the structure and function of materials at the... - Distribution of soot particles in particulate filters of diesel vehicles seen for the first time
Nowadays, all diesel motor vehicles are fitted with a particulate filter as standard, as part of the Euro5 Emission Standard. These filters prevent the harmful soot and ash particles in exhaust gas... - Ultrafast magnetic processes observed "live" using an X-ray laser
In first-of-their-kind experiments performed at the American X-ray laser LCLS, a collaboration led by researchers from the Paul Scherrer Institute has been able to precisely follow how the magnetic...
- A possible new career for a vital biomolecule
As a component of the haemoglobin molecule, porphyrin enables the transport of oxygen within the human body. However, in a slightly altered form, it may find also various applications in technical ...
- Super-Resolution X-ray Microscopy unveils the buried secrets of the nanoworld
A novel super-resolution X-ray microscope developed by a team of researchers from the Paul Scherrer Institut (PSI) and EPFL in Switzerland combines the high penetration power of x-rays with high sp...
