AI supports analysis of metallic materials

"With our specially developed algorithm, we are three times faster"

22-May-2023 - Until now, the analysis of crystalline microstructures in metallic materials has been technically challenging and particularly time-consuming. Researchers from the fields of materials engineering and computer science have now developed an algorithm for this purpose and published it in the ...

Overcoming the optical resolution limit

Microsphere assistance enables interferometric topography measurements

03-Nov-2022 - When measuring with light, the lateral extent of the structures that can be resolved by an optical imaging system is fundamentally diffraction limited. Overcoming this limitation is a topic of great interest in recent research, and several approaches have been published in this area. In a recent ...

Optimized laser pulses drill narrower and deeper holes

28-Apr-2016 - Nanotechnology is at the forefront of today’s advance in areas such as electronics, optical communica-tion and biomedicine. It is about custom-designed structures that are smaller than a micrometer which is already a hundredth of the diameter of a human hair. These so-called nanostructures ...

Where electrons get stuck in traffic

17-Aug-2011 - The thinnest wire in the world, made from pure gold, is being examined by physicists from the universities of Würzburg and Kassel. Its exceptional electrical conductivity is causing quite a stir: the electrons do not move freely through the wire, but like cars in stop-and-go traffic. Normally, ...

Opening the door to unexplored carbene chemistry

26-Oct-2010 - Scientists in Germany have shed new light on the addition of small molecules to the ubiquitous N-heterocyclic carbenes (NHCs), previously thought to be impossible for NHCs. Ulrich Siemeling and colleagues have shown that stable NHCs can show strongly enhanced reactivities towards fundamentally ...
