Neutrophil‐Mimetic MRI Enables Ultra‐Early Detection of Vascular Inflammation After Stroke
Advanced Healthcare Materials, EarlyView.In this study, we developed neutrophil‐mimetic MRI probes that detect ultra‐early neuroinflammation following ischemic stroke by targeting E‐selectin. Within seconds of their injection, these microparticles mimic initial leukocyte adhesion to the activated cerebral endothelium.

Experimental study on vortex induced vibration of risers with fairing considering wake interference
International Journal of Naval Architecture and Ocean Engineering, 2017 Vortex Induced Vibration (VIV) is a typical flow-structure interference phenomenon which causes an unsteady flow pattern due to vortex shedding at or near the structure's natural frequency leading to resonant vibrations.

Enhancing Biogenic Formic Acid Production in the Modified OxFA Process by Acetonitrile Addition
Advanced Science, EarlyView.In this study, the beneficial effect of using acetonitrile as a co‐solvent in the modified OxFA process is shown, outperforming methanol, demonstrating improved reaction kinetics combined with high selectivity for the HPA‐2 (H5PV2Mo10O40) catalyzed oxidation of xylose to FA.

Ban Glyphosate—Does It Affect the Swedish Farmers' Willingness to Grow Cover Crops?
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT The cultivation of cover crops is one of the new Eco‐scheme practices introduced in Sweden. This study examines how the design of policy attributes of these schemes influences farmers' willingness to grow cover crops on arable land, with particular focus on the potential impact of a glyphosate ban.
