The Microstructure and High‐temperature Cycle Oxidation Mechanism of the Nickel‐Based Superalloy Surface Treated by Laser Shock Processing and Ion Implantation at 1100 °C

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
Laser shock processingcombination with Hf ion implantation results in dual modification on the surface of GH202 nickel‐based superalloy, which induces a large number of crystal defects, providing channels for the diffusion of metal cations. Hf ion implantation forms an amorphous HfO2 layer.

Static Stretching Acutely Reduces the Ergogenic Effects of Caffeine on Sprint Performance but Not Maximal Ball Velocity in Football Players

open access: yesEuropean Journal of Sport Science, Volume 26, Issue 2, February 2026.
ABSTRACT This study aimed to investigate the independent and combined effects of caffeine and static stretching (SS) on maximal ball velocity and 30‐m sprint performance. Sixteen male amateur football players performed 30‐m sprint and an instep kicking ball velocity test under six conditions.

Friends or foes? Polyploidy and competition in a grassland geophyte

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Previous studies have suggested polyploids may possess a competitive advantage over diploids, due to their larger size, increased vigour or ability to better respond to abiotic stress. However, few studies have tested the effect of polyploidy on competitive ability directly, and only relatively recently has this oversight begun to be addressed. Here we

Magnon‐Mediated Long‐Range Entanglement in a Spin‐1/2 Heisenberg Chain Coupled to Magnetic Skyrmions

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 2, February 2026.
Magnetic skyrmions generate via their stray magnetic fields, entanglement in a nearby interacting spin chain and control the transfer of information encoded in the spin excitations. ABSTRACT Magnetic skyrmionic stray fields are functionalizable to trigger, maintain, and steer quantum entanglement in a coupled chain of localized spins.
