Summary: A sandwich-like scaffold was developed in this study, consisting of hemostatic sponges made of sodium carboxymethyl cellulose as the top and bottom layers, and an anti-adhesion fibrous membrane with poly-lactic-co-glycolic acid and polyethylene glycol-polylactic acid block copolymer as the intermediate layer. This scaffold serves as a physical barrier, preserving morphological integrity and having hemostasis and anti-adhesion properties, potentially reducing the activation level of coagulation factors and bleeding.

Summary: In this study, ant-nest type porous (ANP) scaffolds consisting of CO(3)Ap were fabricated using calcium carbonate powder or slurry and two types of polyurethane foam. The ANP structures displayed a clear structural advantage in bone regeneration, owing to the promotion of cell and tissue migration throughout the scaffolds. ANP-structured CO(3)Ap scaffolds, especially those with highest porosity, interconnectivity, and smallest strut thickness, showed mechanical strength comparable to cancellous bone and resulted in cancellous bone-like bone tissue regeneration at 12 weeks of healing.

Summary: This study investigates the effect and evolution of frost condensation on a micro-nano structured Ni metal surface. The ice adhesion strength to the porous-structured surface is found to change with both surface morphology and different stages of frosting coverage. The study shows that the wettabilty of the porous-structured surface under different frosting coverage affects the ice adhesion strength by influencing the infiltration state of the surface and resulting in different mechanical interlocking, air-pockets, and cracks states at the ice solid interface.

Summary: In this paper, a novel OTA method is proposed that considers the relationship between tolerance of machine tools' key parts and volumetric error. A volumetric error prediction model is established based on the bridge between geometric error and tolerance. Additionally, a Processing Simplicity Index (PSI) is introduced to replace manufacturing cost and a tolerance-PSI model is established. An OTA model is formulated to minimize volumetric error and maximize PSI. The feasibility and effectiveness of the method are validated through simulations and experiments.

Summary: This paper studies the electromechanical behavior of elliptical APAs by analyzing the multi-domain dynamics of piezoelectric stacks and compliant mechanisms using a novel electro-mechanical transfer matrix method. An analytical electro-elasto transfer matrix of piezoelectric stacks operating at the d33 mode is derived in the form of Taylor's series. The dynamic response spectrum of displacement and impedance for elliptical APAs is accurately captured by this electro-mechanical model, and different topologies of elliptical APAs are compared to suggest the optimal configuration.
