Movement of atoms viewed at 100 times higher than previous resolution

06.05.2005


A paper published in Nature, by scientists at the Universities of Sheffield and Warwick and the European Synchrotron Radiation Facility, describes how experts have used X-rays to see structures in unprecedented detail at the atomic scale. The technique is 100 times more sensitive than any other method, and has the potential to allow scientists to improve things like data storage, healthcare sensors and security systems.



Prof Mike Gibbs, of the Department of Engineering Materials at the University of Sheffield explains, “We have known for some time that when certain magnetic materials are exposed to a magnetic field they lengthen or contract slightly. However, we still don’t have a detailed understanding”.

“This new technique uses X rays to look at the movement of atoms with unprecedented resolution; 100 times better than ever achieved before.”


“Once we can look at atom positions in this way, we will get a much better idea about the atomic structures of a range of materials, meaning that we will be able refine our understanding of how structures and materials are made up. This should lead to improvements in a wide range of technologies in the future.”

Dr. Robert Pettifer, of the University of Warwick says, “To improve a technique by two orders of magnitude means that phenomena can now be investigated which produce subtle changes in the local atomic environment. For example, the ways atoms respond to temperature, electric field and pressure as well as the magnetic field investigated in our paper can now be investigated. Movements comparable to the size of a nucleus can now be resolved. The technique will be especially valuable for materials which are not easily investigated by more conventional techniques such as glasses and thin films.

“We can see applications in such diverse things such as computer disks, domestic refrigerators, and understanding the Earth’s core.”

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
