Nanoparticles drill holes at will in silicon
Industrially usable technique for producing porous silicon and glass opens up fresh perspectives for numerous applications
21-Feb-2023 - A Hamburg-based research team has developed a new method for producing a network of large to very fine pores in silicon and glass. At DESY’s X-ray source PETRA III, scientists led by DESY researchers Stella Gries and Patrick Huber were able to analyse the porosity using X-ray tomography. The ...
Tomography shows high potential of copper sulphide solid-state batteries
Processes during charging and discharging observed
30-Nov-2022 - Solid-state batteries enable even higher energy densities than lithium-ion batteries with high safety. A team led by Prof. Philipp Adelhelm and Dr. Ingo Manke succeeded in observing a solid-state battery during charging and discharging and creating high-resolution 3D images. This showed that ...
Research paves the way for stronger alloys
High-speed synchrotron X-ray tomography ‘photograph’ the changing crystal structures in molten alloys as they cool
07-Jun-2022 - Scientists from the University of Birmingham have described how microscopic crystals grow and change shape in molten metals as they cool, in research that is breaking new ground in alloy research and paves the way for improving the tensile strength of alloys used in casting and welding. Their ...
Seeing more deeply into nanomaterials
New 3D imaging tool reveals engineered and self-assembled nanoparticle lattices with highest resolution yet
21-Apr-2022 - From designing new biomaterials to novel photonic devices, new materials built through a process called bottom-up nanofabrication, or self-assembly, are opening up pathways to new technologies with properties tuned at the nanoscale. However, to fully unlock the potential of these new materials, ...
Using neutrons and X-rays to analyse the ageing of lithium batteries
11-Feb-2020 - An international team has used neutron and X-ray tomography to investigate the dynamic processes that lead to capacity degradation at the electrodes in lithium batteries. Using a new mathematical method, it was possible to virtually unwind electrodes that had been wound into the form of a compact ...
3D X-rays measure particle movement inside lithium ion batteries
23-May-2018 - Lithium ion batteries have come a long way since their introduction in the late 1990s. They're used in many everyday devices, such as laptop computers, mobile phones, and medical devices, as well as automotive and aerospace platforms, and others. However, lithium ion battery performance still can ...
