Stroke affects around 15 million people globally every year according to the WHO. Stroke can lead to significant health consequences or even death, and further knowledge of causes for prevention is a priority. Atherosclerotic plaques that can rupture and cause stroke has been investigated by a combination of X-ray imaging and machine learning to understand more about stability and risks.
Nano-focused X-rays aid integrated circuit development
A modern chip contains billions of transistors. The size of individual features is just a couple of tens of nanometres. With decreasing size follows increased demands on material control and characterisation down to the atomic scale. The nano-focused X-ray beam at beamline NanoMAX prove to be a useful tool for investigating electromigration, a significant cause of failure in on-chip interconnects.
Research done at MAX IV contributes to CIGS solar cell world record
A recent publication from Uppsala University reported a world record for efficiency for a CIGS solar cell. Nano X-ray Fluorescence imaging was done at beamline NanoMAX. With this method, the researchers can detect which elements are present in the sample on the nanometre scale. By scanning the sample, they can acquire an image with a
X-ray eyes on artifact from shipwreck Gribshunden
When history meets present-day science fascinating things reveal themselves. In such a case, a sample of chain mail from the 15th century Danish flagship, Gribshunden, was recently analysed at MAX IV’s NanoMAX beamline. Researchers from Lund University want to know more about the structural and chemical makeup of the metal to give us a window into Sweden’s past.
Oxygen cycling reveals path to next-gen ferroelectric devices
Research is heating up to achieve greater fundamental understanding of the mechanism of ferroelectricity in hafnia-based materials, a crucial step in the development of next generation devices. New findings from the University of Groningen (RUG) in the journal Science define the key role of oxygen for greater miniaturization potential and structural stability beyond that of standard ferroelectric materials used in low-power memories. Electron microscopy and MAX IV’s NanoMAX beamline have illuminated the nature of polarization in thin films of hafnium zirconium oxide for ferroelectronics.
Metal industry giant conducts experiments at MAX IV
Sandvik Coromant and Chalmers University of Technology teamed up to conduct experiments for increasing the product lifetime of metal cutting tools. With the help of the NanoMAX beamline at MAX IV, a team of scientists and R&D professionals will further study the atomic structure of the Titanium Aluminium Nitride (TiAlN) coatings. What makes metal cutting tools
4th generation X-ray brilliance and nanoscale microscopy reveal clearest crystalline form
To capture extraordinary nanoscale details in crystallography takes the powerful coherent flux of a 4th generation light source. Recent work in Light: Science & Applications by an international research team has revealed 3D images of a complex crystalline star structure using Bragg ptychography and new advanced analysis tools at MAX IV’s NanoMAX beamline. The results demonstrate the possibility of unprecedented data quality beyond experimental limitations from new synchrotron sources.
Scientists probe ferroelectric domains in curved free-standing superlattices
By growing superlattices consisting of ferroelectric and non-ferroelectric transition metal oxides and releasing them from their underlying substrates, researchers explore polarization patterns in curved geometries.
Using strain to control echoes in ultrafast optics
Researchers at MAX IV measured echoes produced by silicon crystals using the coherent X-ray based technique, tele-ptychography, at NanoMAX imaging beamline. Their findings reveal that strain can be used to tune the time delay of echoes, an important step for tailoring ultrafast X-ray optics.
