Tribocorrosion behavior of Al-based amorphous coatings prepared by different spraying methods
The correlation between the wear behavior of three types of Al-based amorphous coatings prepared by low-temperature high-velocity oxygen fuel (LT-HVOF), high-velocity air fuel (HVAF) and cold spraying (CS), and the corrosion behavior of the coatings has ...

Surface‐initiated photoiniferter‐mediated polymerization (SI‐PIMP) enables the controlled growth of UHMW polymer brushes with multi‐micrometer thicknesses, bridging conventional brushes and bulk‐like coatings. UHMW brushes are synthesized through a controlled/living process; they provide low friction and enhanced wear resistance under aqueous ...

Molecular rotors are fluorescent molecules that are sensitive to viscosity and temperature variations in the environment. They exhibit a direct correlation between fluorescence and viscosity within Newtonian fluids. However, this correlation becomes less straightforward in complex systems.

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe
By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.

Development of a friction model for the numerical simulation of clinching processes
In numerical simulations of mechanical joining processes, such as clinching, modeling of material behavior is of decisive importance. In addition to the correct representation of plasticity and damage mechanisms, this primarily includes modeling of the ...

Collagen II coatings support the formation of synovial fluid nanofilms, while collagen I coatings do not. Both bind recombinant equine lubricin similarly. These findings may help explain articular cartilage surface joint dysfunction, inform biomaterial design for synovial joint repair, and expand on lubricin‐based osteoarthritis therapies.
