Electronics built from ferroelectric materials have low power consumption and are well-suited for information storage. Their competitiveness depends on developing novel architectures on the nanoscale. A research team from Lund University and ETH Zurich in Switzerland has used the NanoMAX beamline at MAX IV to image through metal contacts on the ferroelectric material bismuth ferrite to see how they affect the material beneath them.
Beamline Collaborations through MAX IV’s Shared Postdocs: Leonardo Oliveira
Collaboration with the user community is a core part of MAX IV’s work. One joint initiative is enabled through close interaction with universities, with postdoctoral researchers dividing their time between a university research group and the synchrotron.
Imagine if you move the beam
Think differently, or in some cases, look at the problem from an entirely new angle. An international research group from PETRA III synchrotron in Germany and MAX IV has developed a new method for the scanning lens-less imaging technique known as ptychography. The system is designed for various sample environments, in situ and in operando conditions, and is portable, enabling usage at different beamlines or synchrotrons.
The great planetary reset: Mapping glass pearls
Their days were numbered, all manner of Cretaceous life in kingdom plantae and animalia. Those that survived the impact winter became our modern groups of terrestrial and aquatic plants, animals, and marine plankton. Scientists want to understand how the Chicxulub asteroid that hit Earth 66 million years ago changed the conditions for life on the planet and veiled the sun for so many years, leading to the extinction of the dinosaurs. Secrets to this understanding are locked in the asteroid’s physical composition. An international research group has now produced a unique elemental map of the spherules formed by the asteroid impact, with data from MAX IV’s Balder and NanoMAX beamlines. The findings may better explain the aerosol cloud formation that catalysed extinction-level climate change.
A path to polymerize metallic hydrogen?
An international research group reports in Nature the observation of the phase transition of a hexagonal close-packed (HCP) crystal structure of hydrogen to a 6-fold larger hydrogen supercell. The findings describe polymerization activity at extreme pressures which reveals how atoms arrange themselves in solid hydrogen and offers clues to the formation of metallic hydrogen. The study includes X-ray diffraction (XRD) data from MAX IV’s NanoMAX beamline.
High-resolution imaging provides clues to lung disease
Researchers have imaged lung tissue affected by Idiopathic Pulmonary Fibrosis (IPF) with nanometre resolution. They managed to capture differences in the distribution of trace elements compared to a healthy lung. The result is a step towards better understanding the body at the nanoscale and managing this and other currently untreatable diseases.
Looking for clues in stroke-causing plaques with X-rays and machine learning
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.
