Summary: In this study, metallic substrates with a nanocrystalline grain size were structured down to the micro-and nanometre range using a room temperature nanoimprinting process. Hard metal dies patterned by Direct Laser Interference Patterning (DLIP) were used to deform the metallic substrates, transferring the pattern onto a nanocrystalline CuZn30 model alloy. The replication process allowed for the formation of separated dimples and LIPSS on the alloy surface.

Summary: An acrylic resin guide rail was designed and 3D printed to facilitate femtosecond laser surface microstructuring on zirconia dental implant, resulting in two surface topographies: microgrooves and nanoparticles. The fracture strength of control, microgrooved, and nanoparticles implants were 907.8 +/- 59.0 N, 793.7 +/- 83.3 N, and 755.6 +/- 144.5 N, respectively. Using femtosecond laser with the advocated guide rail is an effective method to fabricate micro-nano hierarchical topographies on zirconia dental implants precisely.

Summary: One challenge in biosensing technology is detecting very low concentrations of analytes. The fluorescence interference contrast (FLIC) technique improves sensitivity by selectively amplifying or suppressing the emission of a fluorophore-labeled biomolecule. FLIC's extreme sensitivity to wavelength can be a problem due to variations in the fluorophore's vertical position.

Summary: Non-dimensional similarity groups and analytically solvable proximity equations can estimate fluid film parameters in elastohydrodynamically lubricated contacts. In this study, machine learning and artificial intelligence approaches are shown to predict these parameters more efficiently and accurately than EHL simulations and proximity equations. The architecture of artificial neural networks and the activation functions have an impact on prediction accuracy. Artificial neural networks can predict local film thickness 25 times faster than FE-based EHL simulations. This advancement in prediction methods can enhance multibody system dynamics simulations.

Summary: Solution-processed multilayer Ti3C2Tx-MoS2 blends were spray-coated onto rough steel surfaces to achieve superlubricity. The tribological performance of these nanocomposites was evaluated and found to have superior friction properties, surpassing previous reports for individual MoS2 and Ti3C2Tx materials. The formation of a robust tribolayer at high contact pressures and sliding speeds was responsible for the exceptional performance. This study presents the lowest friction achieved by MoS2 or MXene or any combination of the two to date.

Summary: The mechanical performance and surface friction of graphene oxide (GO) depend on the number of layers. The nanowear resistance of GO nanosheets on a silicon oxide substrate shows a non-monotonic layer-dependence. As the thickness of GO increases, the nanowear resistance first decreases and then increases, with a critical number of layers at 4. This change corresponds to a shift in the wear mode from overall removal to progressive layer-by-layer removal.
