Influence of Ti-6Al-4V Scaffold Architecture on Early Cellular Responses Relevant to Bone Regeneration

Background: Optimal porosity and surface area of additively manufactured Ti-6Al-4V scaffolds for early human mesenchymal stem cell (hMSC) retention remain unclear, despite their importance in reconstruction of critical-sized bone defects. This study evaluated scaffold architectures fulfilling biomechanical criteria for...

Influence of spur-gear tooth-profile geometry on mesh efficiency and transmission error: A common-benchmark multi-objective comparison

Reducing gear-mesh loss without compromising STE, DTE and load capacity is central to high-performance transmission design. Non-involute tooth-flank geometries can redistribute sliding, contact conformity and mesh compliance, but published comparisons often confound geometry with benchmark and modelling assumptions. Th...
