This study presented a unique process of mechanical alloying (MA) and laser powder bed fusion (LPBF) to prepare heterogeneous grain structure (HGS) Zn with strength-plasticity synergy. The results showed that the MA-treatment significantly refined sizes nano-scale contributed formation HGS powders. Moreover, ultra-fast heating cooling LPBF inhibited growth resulted in specific core/shell HGS, wherein cores (micron-grains) were surrounded by interconnected shells (nano-grains). Notably,...
Magnetostrictive Fe–Ga alloys have been demonstrated potentialities for numerous applications, whereas, suffering a tradeoff between large magnetostrictive strain and high sensitivity. Herein, bulk polycrystalline Fe81Ga19 were prepared by laser-beam powder bed fusion (LPBF) then annealed in magnetic field manipulating the comprehensive properties. Results indicate that <001> oriented grains are developed LPBF-prepared due to temperature gradient. After annealing (MFA), domains within...
The aggregation of graphene oxide (GO) is considered as main challenge, although GO possesses excellent mechanical properties which arouses widespread attention reinforcement for polymers.In this study, silicon dioxide (SiO2) nanoparticles were decorated onto surface nanosheets through in situ growth method promoting dispersion poly(l-lactic acid) (PLLA) bone scaffold.Hydroxyl and carboxyl functional groups provided sites SiO2 nucleation, grew with hydrolysis polycondensation tetraethyl...
Fe3O4 nanoparticles are highly desired for constructing endogenous magnetic microenvironment in scaffold to accelerate bone regeneration due their superior magnetism. However, random arrangement easily leads mutual consumption of poles, thereby weakening the stimulation effect.In this study, nanochains synthesized by magnetic-field-guided interface co-assembly nanoparticles. In detail, multiple aligned along direction force lines and connected series form nanochain structures under an...
Mg has been considered a promising biomaterial for bone implants. However, the poor corrosion resistance become its main undesirable property. In this study, both alloying Mn and laser-melting were applied to enhance resistance. The resistance, mechanical properties, microstructure of rapid laser-melted Mg-xMn (x = 0-3 wt %) alloys investigated. composed dendrite grains, grains size decreased with increasing Mn. Moreover, could dissolve induce crystal lattice distortion matrix during...
A nano-sandwich construct was built by combining two-dimensional graphene nanosheets (GNSs) and one-dimensional carbon nanotubes (CNTs) to improve the mechanical properties of hydroxyapatite-polyetheretherketone (HAP-PEEK) scaffolds for bone tissue engineering. In this construct, long tubular CNTs penetrated interlayers prevented their aggregation, increasing effective contact area between matrix. The combination GNSs in a weight ratio 2:8 facilitated dispersion each other provided...
Abstract N6‐methyladenosine (m 6 A) is one of the main epitranscriptomic modifications that accelerates progression malignant tumors by modifying RNA. Methyltransferase‐like 16 (METTL16) a newly identified methyltransferase has been found to play an important oncogenic role in few malignancies; however, its function osteosarcoma (OS) remains unclear. In this study, METTL16 was be upregulated OS tissues, and associated with poor prognosis patients. Functionally, substantially promoted cell...
Although forsterite (Mg₂SiO₄) possesses good biocompatibility and suitable mechanical properties, the insufficient bioactivity degradability hinders its further application. In this study, a novel MgO-CaO-SiO₂ system was developed by adding wollastonite (CaSiO₃) into Mg₂SiO₄ to fabricate bone scaffolds via selective laser sintering (SLS). The apatite-forming ability of were enhanced because degradation CaSiO₃ could form silanol groups, which offer nucleation sites for apatite. Meanwhile,...
Abstract Treating bone infections and ensuring recovery is one of the major global problems facing modern orthopedics. Prolonged antibiotic use may increase risk antimicrobial resistance, inflammation caused by biofilms can obstruct tissue healing, making infection treatment even more challenging. The optimal strategy combines immune response modification to promote osteogenesis with effective bacterial removal that does not require long‐term use. A one‐step plasma immersion ion implantation...
It remains the primary issue to enhance corrosion resistance of Mg alloys for their clinical applications. In this study, β-tricalcium phosphate (β-TCP) was composited with Mg-6Zn-1Zr (ZK60) using laser rapid solidification improve degradation behavior. Results revealed effectively restrained aggregation β-TCP, which thus homogenously distributed along grain boundaries α-Mg. Significantly, uniformly β-TCP in matrix promoted formation apatite layer on surface, contributed a compact product...
