Ultrafast laser irradiation can trigger anisotropically structured nanoscaled gratinglike arrangements of matter, the laser-induced periodic surface structures (LIPSSs). We demonstrate here that formation LIPSS is intrinsically related to coherence field. Employing several test materials allow large optical excursions, we observe effect randomizing spatial phase in generating finite domains ripples. Using three-dimensional finite-difference time-domain methods, evaluate energy deposition...
Bone morphology protein-2 (BMP-2) encapsulated chitosan/chondrotin sulfate nanoparticles (CHI/CS NPs) are developed to enhance ectopic bone formation on biphasic calcium phosphate (BCP) scaffolds. BMP-2 contained CHI/CS NPs were prepared by a simple and mild polyelectrolyte complexation process. It does not involve harsh organic solvents high temperature, therefore retain growth factors activity. These immobilized BCP scaffolds, realize the sustained release of from The bare NP loaded...
High-entropy carbide ceramics have attracted extensive attentions for potential applications as high temperature structural materials, the mechanical and tribological performance of (TiNbTaWMo)C high-entropy carbides over wide range combined with oxidation behavior were investigated in present study. successfully prepared from five kinds powders by spark plasma sintering at 2000 °C. The properties room –800 °C studied. Vickers hardness, bending strength fracture toughness sintered are 21.31...
Abstract Various therapeutic platforms have been developed for repairing bone defects. However, scaffolds possess both cortical bone-matching mechanical properties and excellent osteoconductivity load-bearing defects repair is still challenging in the clinic. In this study, inspired by structure of ferroconcrete, a high-strength bifunctional scaffold has combining surface-modified magnesium alloy as internal skeleton bioglass-magnesium phosphate cement osteoconductive matrix. The combines...
The bioactivity and biocompatibility play key roles in the success of dental orthopaedic implants. Although most commercial implant systems use various surface microstructures, ideal multi-scale topographies capable controlling osteointegration have not yielded conclusive results. Inspired by both isotropic adhesion skin structures tree frog toe pads anisotropic corrugated ridges on scales Morpho butterfly wings, composite micro/nano-structures, including array micro-hexagons oriented...
Inspired from falling leaves, ZnO nanorods-nanoslices hierarchical structure (NHS) was constructed to modify the surfaces of two widely used implant materials: titanium (Ti) and tantalum (Ta), respectively. By which means, two-stage release antibacterial active substances were realized address clinical importance long-term broad-spectrum activity. At early stages (within 48 h), NHS exhibited a rapid releasing kill bacteria around immediately. second stage (over 2 weeks), slow realize...
The electrosurgical blade is the most common invasive surgical instrument in a cutting and hemostasis process; however, easily leads to adhesion of overheated soft tissues on blades induces potential danger for patients. To minimize adhesive tissues, we proposed one-step surface texturing method fabricate anti-adhesive biomimetic scales stainless steel 316L rapidly based self-organized microstructures induced by long-pulse fiber laser, which was inspired excellent performances anti-adhesion...
In this study, borosilicate bio-glass (BG) was incorporated into magnesium phosphate cement (MPC) for the purpose of developing an injectable and bioactive composite with suitable physicochemical biocompatible performance. Results show that BG-incorporated MPC possesses excellent injectability, can be used to fill in different 3D printed defect models using a syringe moderate setting time. Meanwhile, BG retard time adjust exothermic temperature MPC. When MPC/BG ratio 3:1 (MPC3-BG), its...
This study presents a novel reflective fiber Fabry–Perot (F–P) salinity sensor. The sensor employs femtosecond laser to fabricate an open liquid cavity, facilitating the unobstructed ingress and egress of liquid, thereby enabling direct involvement in light transmission. Variations refractive index induce corresponding changes effective optical path, which subsequently influences output spectrum. dimensions quality are meticulously regulated through combination cutting chemical polishing,...
Abstract To compensate for the growing need flexibility in pressure-sensing wearable devices, solid–liquid mixed-phase sensors have been improved to meet application needs.
