Deposition of VS2/MoS2 bilayer layers of 2D material on nickel inverse opal structural substrates by SILAR and ECD processes as supercapacitor electrodes.

The composition, microstructure, and electrochemical properties of the two kinds of thin film electrode materials, namely VS2/MoS2/Ni-IOS and VS2/MoS2/ Ni-foam, were analyzed. The research results indicate that the self-assembled photonic crystal templates with adjusted EPSA processing parameters (100 V/cm; 7 min) would lead to an FCC closest-packed structure. Metallic nickel inverse opal structure (IOS) photonic crystals whose thickness can be freely regulated simply by electrochemical deposition time.

Enhancing Bone Cement Efficacy with Hydrogel Beads Synthesized by Droplet Microfluidics.

Effective filling materials, typically bone cements, are essential for providing mechanical support during bone fracture treatment. A current challenge with bone cement lies in achieving continuous drug release and forming porous structures that facilitate cell migration and enhance osteoconductivity. We report a droplet microfluidics-based method for synthesizing uniform-sized gelatin hydrogel beads.

Fabrication of Glutaraldehyde Vapor Treated PVA/SA/GO/ZnO Electrospun Nanofibers with High Liquid Absorbability for Antimicrobial of .

In this study, we aim to develop organic-inorganic hybrid nanofibers containing high moisture retention and good mechanical performance as an antimicrobial dressing platform. The main theme of this work focuses on several technical tasks including (a) the electrospinning process (ESP) to produce organic polyvinyl alcohol/sodium alginate (PVA/SA) nanofibers with an excellent diameter uniformity and fibrous orientation, (b) the fabrication of inorganic nanoparticles (NPs) as graphene oxide (GO) and ZnO NPs to be added to PVA/SA nanofibers for enhancement of the mechanical properties and an antibacterial function to , and then (c) the crosslinking process for PVA/SA/GO/ZnO hybrid nanofibers in glutaraldehyde (GA) vapor atmosphere to improve the hydrophilicity and moisture absorption of specimens. Our results clearly indicate that the uniformity nanofiber with 7 wt% PVA and 2 wt% SA condition demonstrates 199 ± 22 nm in diameter using an electrospinning precursor solution of 355 cP in viscosity by the ESP process.

Electrochemically Deposited MoS and MnS Multilayers on Nickel Substrates in Inverse Opal Structure as Supercapacitor Microelectrodes.

High-dispersion polystyrene (PS) microspheres with monodispersity were successfully synthesized by the non-emulsification polymerization method, and three-dimensional (3D) photonic crystals of PS microspheres were fabricated by electrophoretic self-assembly (EPSA). The metal nickel inverse opal structure (IOS) photonic crystal, of which the structural thickness can be freely adjusted via electrochemical deposition (ECD), and subsequently, MnS/MoS/Ni-IOS specimens were also prepared by ECD. Excellent specific capacitance values (1880 F/g) were obtained at a charge current density of 5 A/g.
