Atoms have the habit of jumping through solids - a practice that physicists have recently been able to follow for the first time using a brand new method. This scientific advance was made possible thanks to the utilisation of cutting-edge X-ray sources, known as electron synchrotrons.
The detailed findings of the project, backed by the Austrian Science Fund FWF, were recently published in the prestigious journal NATURE MATERIALS. The work unlocks new potential for the study of material ageing processes at the atomic level.Now and then, things can get pretty "wild" in solids. For example, billions of atoms in a gold ring can shift position every second. However, it is not just ordinary people who cannot see the atoms jumping around - physicists too have long been unable to witness this process for themselves. However, there is one very good reason in particular why scientists should want to change all that. The restlessness of atoms is responsible for ageing, and therefore the loss of specific material properties.

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
Theoretical physicists propose to use negative interference to control heat flow in quantum devices. Study published in Physical Review Letters
Quantum computer parts are sensitive and need to be cooled to very low temperatures. Their tiny size makes them particularly susceptible to a temperature...
Let’s say the armrest is broken in your vintage car. As things stand, you would need a lot of luck and persistence to find the right spare part. But in the world of Industrie 4.0 and production with batch sizes of one, you can simply scan the armrest and print it out. This is made possible by the first ever 3D scanner capable of working autonomously and in real time. The autonomous scanning system will be on display at the Hannover Messe Preview on February 6 and at the Hannover Messe proper from April 23 to 27, 2018 (Hall 6, Booth A30).
Part of the charm of vintage cars is that they stopped making them long ago, so it is special when you do see one out on the roads. If something breaks or...
