Magnesium alloys have better biocompatibility and biodegradability than conventional biomedical metal materials, but the corrosion resistance is so poor that implant loses its mechanical integrity before damaged tissue completely recovers. In this study, ZEK100 magnesium alloy was pre-deformed with a high-pressure torsion (HPT) process then fabricated hydroxyapatite (HA) coatings different contents of Mg(OH)2 nanopowder via hydrothermal method. The specimens were characterized by scanning...
Silver nanoparticles (AgNPs) are emerging as powerful tools in healthcare due to their unique properties, including antimicrobial activity, high surface area, and biocompatibility. They widely used medical applications such wound healing, drug delivery, cancer therapy, diagnostics, particularly for combating multidrug-resistant bacteria. AgNPs enhance the effectiveness of traditional antibiotics show potential synergistic therapies with other nanomaterials. However, challenges remain...
Purpose The paper aims to study the effect of sintering temperature on microstructure, shear strength and ratcheting fatigue life nanosilver sintered lap joint. In addition, Gerber model is used predict lives joints at different temperatures. Design/methodology/approach this paper, were prepared three temperatures 250 °C, 280 °C 310 °C. bonding quality was characterized by scanning electron microscopy, X-ray diffraction, transmission microscope tests, long-term reliability studied conducting...
Abstract Ultrahigh molecular weight polyethylene (UHMWPE) artificial joint has remained the preferred polymer component in total replacement surgery. However, more and concerns have been raised about failure of UHMWPE components due to initiation propagation cracks at notches with fixed functions. For this reason, biaxial fatigue crack growth (FCG) experiments reinforced by carbon nanofibers (CNF) hydroxyapatite (HA) were carried out using elastic–plastic fracture mechanics theory. The FCG...
Power electronics may operate at high temperatures even above 200∘C. In recent years, silver sintering technology is being gradually applied in high-temperature power electronic packaging due to its excellent thermal, electrical, and mechanical properties. Compared with early pressure-assisted technology, pressureless can simplify the process reduce capital investment. Silver chip-level substrate-level presented as follows: firstly, traditional state-of-the-art technologies are reviewed:...
Silver paste, as a novel thermal interface material, has wide applications in elevated temperature power electronics. In practice, usually pressure higher than 5 MPa is necessary for large‐area bonding by silver regardless the fact that uneven may cause fracture of brittle components such chips and ceramic substrates. Herein, feasibility using liquid dispersant to assist sintering proved. The introduced method can obtain sound with lower MPa. employed dispersants, namely, α terpineol,...
Mandibular defect repair has always been a clinical challenge, facing technical bottleneck. The new materials directly affect technological breakthroughs in mandibular field. Our aim is to fabricate scaffold for repairing with advanced biomaterials. Therefore, novel dual-channel printed consisting of silk fibroin/collagen type I /hydroxyapatite (SCH) and polycaprolactone/hydroxyapatite (PCL/HA) was fabricated by 3D printing technology double nozzles. mechanical properties behaviors were...
