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.

Method to map catalyst structure and local gas environment simultaneously enables depiction of transitional surface structures

One of the key challenges in catalysis research is to understand how catalysts’ structure and function relate to each other. Regardless of the type of catalyst in question, structure and function are dynamic with a strong dependence on the localized reaction conditions such as temperature, pressure, and gas composition just above the catalyst surface. Now, researchers developed a new event-averaging-based method employing time-resolved ambient pressure photoelectron spectroscopy to map catalyst structure and local gas environment simultaneously while reaction conditions change rapidly.

The role of synthesis gas in tomorrow’s sustainable fuels

In a new publication in Nature Communications, a team from the Dutch company Syngaschem BV and the Dutch Institute for Fundamental Energy Research elucidates for the first time some aspects of the Fischer-Tropsch reaction, used for converting synthesis gas into synthetic fuels. Analysis performed at the HIPPIE beamline at MAX IV was instrumental to achieving these results.

Identifying chemical content to increase the usefulness of solid waste ashes

Fortum Waste Solutions, Sysav, Eon, Stena and NOAH, in collaboration with Researchers from RISE and Chalmers, used beamline Balder to identify chemical species of copper and zinc in ashes that remain after burning solid waste. Not all forms of the metals in ashes pose the same risk to the environment. Therefore, more detailed knowledge can increase the possible uses of the ashes.

Honeycomb borophene: myth or reality?

Scientists examined whether honeycomb boron can function as a structural analogue 2D material to graphene. Employing core-level X-ray spectroscopies, scanning tunneling microscopy, and DFT calculations, they analyzed the structure and electronic properties of honeycomb boron after its reaction with aluminum. They found that although it resembles graphene in electronic structure to some extent, it fails to form a quasi-freestanding monolayer on aluminum. This lack of a freestanding state is a clear difference from the behavior of graphene or monolayer hexagonal boron nitride (h-BN) on lattice-mismatched metal surfaces.

Dear user community: CoSAXS beamline is performance ready

A successful, first rigorous test of CoSAXS, the Small-Angle X-ray Scattering beamline at MAX IV has now completed. A collaboration of scientists from NanoMAX, Balder, and CoSAXS beamlines demonstrated the accuracy, capabilities, and most especially, coherence properties of the instrument. The work marks the first experimental measurements for coherence in a SAXS beamline at a fourth generation synchrotron.

Designing a Model Catalyst for Large-Scale Biofuel Production

The future of efficient biofuel production is within reach. With measurements from MAX IV’s SPECIES beamline, a group from Lund University and RISE, Research Institutes of Sweden, has successfully developed a model catalyst that, once tuned, holds the potential to significantly improve the treatment process for the large-scale manufacture of viable biofuels from lignin. Lignin is a plant polymer only secondary in abundance to cellulose in nature.
