Bone tissue engineering is the main method for repairing large segment bone defects. In this study, a layer of bioactive MgO nanoparticles was wrapped on surface spherical Zn powders, which allowed to be incorporated into 3D-printed matrix and improved biodegradation biocompatibility matrix. The results showed that porous pure scaffolds Zn/MgO with skeletal-gyroid (G) model structure were successfully prepared by selective laser melting (SLM). average porosity two 59.3 60.0%, respectively....
The effects of extrusion temperatures on the microstructure, mechanical properties, and corrosion performance biomedical Mg-1Zn-0.4Ca-1MgO composites were systematically investigated. results indicated that lower notably refined grain size promoted formation numerous nano-scaled secondary phase particles. sizes 0.8 μm, 1.7 3.4 μm for materials extruded at 280 °C, 310 330 which named ET280, ET310, ET330. finest abundant precipitates enhanced properties composite with a microhardness 86.9 HV,...
MoS<sub>2</sub>nanosheets with higher adsorption capacity for dyes.
An ultra-fine grained (UFG) Mg-1Zn-0.2Ca-1.0MgO composite with an average grain size of 0.49 µm as well excellent combination yield strength (379 MPa) and ductility (10.1%) was produced by one-step extrusion. Subsequent heat treatment at 200 ℃ for 30 min further improved its to 420 MPa elongation 12.1% a slight growth 0.76 µm. Microstructure observations revealed that the precipitation high number density Ca2Mg6Zn3 phase main reason enhanced after ageing treatment. Grain coarsening recovery...
Various kinds of copper sulfides (CuS, a mixture Cu7S4–CuS and Cu9S5) were synthesized by simply adjusting the amount chloride sodium sulfide in solvothermal process. The different molar ratios result formation with various morphologies, such as tiny particle, hexagonal plate octahedron. products characterized X-ray powder diffraction, scanning electron microscopy, transmission microscopy photoelectron spectroscopy. And optical properties recorded means UV-Vis absorption photoluminescence...
Magnesium and its alloys are biodegradable materials with great potential for biomedical development; however, their high rate of degradation in biological environments limits the widespread application these materials. In order to improve corrosion resistance magnesium alloy, a functional calcium phosphate coating was prepared on Mg–3Zn–0.5Zr–0.5Sr alloy by microarc oxidation (MAO) combined chemical deposition fluoridated hydroxyapatite (FHA). A dense calcium–phosphorus 6 μm thick composed...
At present, titanium (Ti) and its alloys are most commonly use in hemostasis clip clinical applications. However, the Ti Clip cannot be absorbed human body produce artifacts on computed tomography (CT), induce clinically relevant hypersensitivity patients. In order to overcome drawbacks of non-degradable clips, an Mg-Zn-Ca alloy operative was fabricated by combining hot extrusion blanking processing. vitro vivo biocompatibility were evaluated L-929 Cells SD rat model respectively. It found...
The effects of nano-CaO contents on the microstructure, mechanical properties and corrosion resistance lean Mg-1Zn alloy were investigated. results showed that addition significantly refined grain size improved alloy. At same time, CaO reacted with molten Mg in situ to form nano-MgO, whose product SBF solution was degradation matrix, resulting enhanced compactness Mg(OH)2 layer reduced rate matrix. had lower due excessively large shedding products. composite 0.5 wt.% best a weight loss 9.875...
The heterostructure of obtained ZnS–CuS can timely transfer and separate photogenerated electrons holes, which enhances their photocatalytic abilities.
Biodegradable devices for medical applications should be with an appropriate degradation rate satisfying the various requirements of bone healing. In this study, composite materials polylactic acid (PLA)/stearic acid-modified magnesium oxide (MgO) a 1 wt% were prepared through blending extrusion, and effects MgO shapes on composites’ properties in vitro vivo investigated. The results showed that long-term behaviors samples depended significantly filler shape. composites is accelerated by...
Biomedical magnesium alloys have become an ideal material for degradable implants because of their similar density and elastic modulus with human bone. In this study, Mg-3Zn-0.2Ca-xAg (x = 0%, 0.1%, 0.3%, 0.5%, 0.7%, wt.%) were fabricated to enhance the comprehensive properties Mg-3Zn-0.2Ca (wt.%) alloys. The microstructure shows that alloy possesses relatively smaller grain size 2.08 μm when addition Ag is 0.3 wt.%. Mg-3Zn-0.2Ca-0.3Ag also owns best mechanical whose elongation, yield...
