Ionic liquids key to sustainable energy storage

High-capacity energy storage systems are an important part of the renewable energy transition and can be realised using RTILs, room temperature ionic liquids, as electrolytes.
A research team from University of Tartu, Estonia, recently used beamline FlexPES to study the stability of RTILs for such applications.

Nano solutions for future supercomputers: resolving the von-Neumann bottleneck

Researchers from Lund University benefitted from MAX IV laboratory to find solutions to the long-standing technological challenge: the von-Neumann bottleneck. After nearly year-long research during the pandemic, they successfully integrated the processor and memory onto a single vertical nanowire in a 3D configuration while showcasing in-memory computing with a minimal footprint.

Deciphering corrosion resistance of superalloys

To develop longer-lasting metallic materials for harsh operating conditions requires understanding of their surface composition, structure and properties. A Swedish research group investigated the surface chemistry and thickness of the protective native oxide layer of nickel superalloys at MAX IV’s FlexPES beamline.

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.
