For the enhancement of the anticorrosion and antibacterial performance of the biomedical alloy Ti6Al4V, a novel Cu incorporated multilayer TaOceramic composite coating Cu-TaO/TaO/TaO-TiO/TiO/Ti (coating codeCu-MTaO) was developed by radio frequency (RF) and direct current (DC) reactive magnetron sputtering. Meanwhile, to better display the multilayer TaO coating mentioned above, a monolayer TaO ceramic coating was deposited onto the surface of Ti6Al4V alloy as a reference. The surface morphology, microstructure, phase constituents, and elemental states of the coating were evaluated by atomic force microscopy, scanning electron microscopy, X-ray diffraction, and X-ray photoelectron spectroscopy, respectively. The adhesion strength, wettability, anticorrosion and antibacterial properties of the coating were examined by a scratch tester, contact angle measurement, electrochemical workstations, and plate counting method, respectively. The results showed that the deposited coatings were amorphous and hydrophobic. Cu doped into the TaO coating existed as CuO and CuO. A TaO-TiO/TiO/Ti multi-interlayer massively enhanced the adhesion strength of the coating, which was 2.9 times stronger than that of the monolayer TaOcoating. The multilayer Cu-MTaO coating revealed a higher corrosion potential and smaller corrosion current density as compared to the uncoated Ti6Al4V, indicating the better anticorrosion performance of Ti6Al4V. Moreover, a 99.8% antibacterial effect of Cu-MTaO coated against obtained.

Although Silicon monoxide (SiO) is regarded as the most promising next-generation anode material, the large volume expansion, poor conductivity, and low initial Coulombic efficiency (ICE) severely hamper its commercialization application. Designing a multilayer conductive skeleton combined with advanced prelithiation technology is considered an effective approach to address these problems. Herein, a reliable strategy is proposed that utilizes MXene and carbon nanotube (CNT) as dual-conductive skeletons to encapsulate SiO through simple electrostatic interaction for high-performance anodes in LIBs, while also performing chemical prelithiation.

Background: We have developed a new hybrid warp-knit fabric for induction of in situ tissue regeneration that has shown appropriate antideterioration properties and expandability in preclinical studies. This study was performed to assess the clinical efficacy and safety of this fabric in the early postoperative period after congenital cardiac surgery.
Methods: The fabric comprises biodegradable (complete degradation period, 2-3 years) and nonbiodegradable yarns coated with cross-linked gelatin.
