Iron organic complexes in Sweden’s boreal rivers significantly contribute to increased iron concentration in open marine waters, X-ray spectroscopy data shows. A Lund University study in Biogeosciences characterizes the role of salinity for iron-loading in estuarine zones, a factor which underpins intensifying seasonal algal blooms in the Baltic Sea.
What doesn’t break you makes you stronger – how to design optimal steels for impact
Your car gets hit by another vehicle, and the steel in its construction is deformed by the impact. The steel isn’t just designed to be strong enough to protect you. It also gets stronger because of the impact. It all has to do with the different arrangements that the atoms inside the steel can assume and under which conditions these so-called phases can exist.
Salts of the Earth aid understanding of Martian salt chemistry
How does one learn more about the characteristics of the Martian atmospheric chemistry and climate system while seated 56 million plus kilometres away? Using MAX IV’s HIPPIE beamline, an international research group studied the surface solvation of salts from Earth’s Qaidam Basin, which bear close resemblance to Martian salts and how these influence the respective planet’s surface. The work also establishes the feasibility of the APXPS technique for future studies with Martian salts.
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 unlock secrets of surface receptor activation opening door to engineer plant-microbe interactions
In a study combining structural biology, biochemical and genetic approaches, scientists showed that plant cell-surface receptors employ a mechanism for error correction responsible for the control of receptor activation and signaling select bacterial symbionts. This demonstration opens the door to potentially manipulating such receptors’ binding sites in legumes and other organisms in the future.
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.
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.
Understanding NUDT15: lessen the efficacy of HCMV treatment
Ganciclovir, a regular medicine used to treat human cytomegalovirus (HCMV) infections, was found less efficient when reacting to human’s NUDT15 enzyme — based on a recent BioMAX study. This finding gives further insight into pharmaceutical treatments’ efficacy in HCMV cases. Although being regarded as a common disease, HCMV infections might cause severe consequences for immunocompromised
Aarhus scientists investigate secrets behind mantis shrimp clubs at DanMAX
Mantis shrimp or stomatopods, intrigue humans due to their beauty but also fierce predatory behavior.
Strong coupling of thin ferromagnet to Manganese Gold compound yields successful antiferromagnetic read-out
Scientists demonstrated a strong coupling of very thin ferromagnetic permalloy layers to the antiferromagnetic spintronics compound Manganese Gold. This enabled them to apply well-established read-out methods commonly applied to ferromagnets in antiferromagnetic spintronics as well.
