Recent advancements have highlighted the potential of decellularized plant scaffolds, such as those derived from <em>Beaucarnea recurvata</em> leaves (BLDS). These offer intrinsic microstructural advantages with solving reproducibility, scalability, incurred cost, and biocompatibility challenges.

By functionalizing BLDS with GSPE, we investigated its impact on osteogenic and odontogenic differentiation of human dental pulp-derived mesenchymal stem cells (DPDMSCs). The modified scaffolds exhibited improved physicochemical properties, including enhanced cell proliferation, protein absorption, scaffold interactions, and upregulated osteogenic and dental marker gene expression.

Through the Mini LED assembly process, with the Mini LED size measuring 150 μm (length) ∗ 100 μm (width) ∗ 70 μm (thickness), polyamide was identified as a facilitator for precise alignment, which enhanced self-alignment capabilities by 68.8 % and improved the accuracy on self-aligned distance from 12.5 μm to 21.1 μm in Mini LED packaging.

This research examines how laser machining affects the wicking dynamics of open microchannels. Microchannels were fabricated on a pre-laser-machined hydrophobic square on a silicon substrate, and their wicking performance, i.e., flow rate, water meniscus shape, and durability, was evaluated under various conditions, including different laser parameters, channel orientation, and engraving designs. Depending on its distribution, surface roughness, influenced by laser parameters, is critical in enhancing or hindering wicking. The laser can create two distinct wicking modes on a single platform. Increased roughness slows wicking in horizontally oriented channels, while in vertically oriented channels, it significantly boosts the capillary rate. The durability of wicking also depends on surface roughness properties; microchannels with tightly structured textures maintain durable wicking independent of their capillary flow rate.

Nanoindentation analysis revealed that the composite containing 10 wt% SiC (TNi10SiC) exhibited significantly higher nanohardness (about 10.3 GPa) and elastic modulus (∼177.7 GPa) than the unreinforced Ti6Al4V alloy (sample T). The improved nanomechanical performance of the composites was attributed to the load-carrying capacity of the hard, <em>in-situ</em> formed reinforcement phases. The anti-wear characteristics of the composites showed that TNi5SiC composite displayed superior wear resistance with a specific wear rate of 4.75 ± 0.34 × 10⁻⁴ mm³/Nm and 2.15 ± 0.34 × 10⁻⁴ mm³/Nm under an applied loads of 10 N and 20 N, respectively, among the sintered samples.

This enhanced tribological behaviour was ascribed to the increased surface hardness, the formation of a stable transfer layer, and the reduction in direct asperity contact at the sliding interfaces.
