Summary: In this study, a multifunctional coating was prepared through layer-by-layer self-assembly, which effectively improved osseointegration of implants. The surface morphology and biomechanical properties of the coating were analyzed, and the feeding consistency and adsorption ratios of peptides were explored. The (TA-OGP@RGD)n composite membrane promoted cell migration, adhesion, osteogenic differentiation, and mineralization, and exhibited excellent osteogenesis and osseointegration in vivo. Additionally, the membrane regulated the balance of reactive oxygen species in the cell growth environment. This study provides a novel approach for constructing multifunctional coatings for implants and has significant application potential in orthopedics and dentistry.

Summary: In recent years, researchers have extensively studied multifunctional inorganic-organic hybrid materials to determine their potential effects on reactivity. This study designed and characterized a hybrid material by combining photocatalytic TiO2 nanoparticles with sodium surfactin (SS), a biosurfactant with high affinity for metal cations and antimicrobial properties. The synthesis methodologies and different TiO2:SS weight ratios were investigated to understand their effects on colloidal, physicochemical, and functional properties. The breaking point between TiO2 and SS single-component trends was identified and different ranges of applicability were determined. At low SS contents, the hybrid material showed preserved photocatalytic properties and additional antimicrobial effects, while at high SS contents, TiO2 photoactivity was inhibited and the hybrid material could be used as a UV blocker. Around the breaking point, the hybrid material exhibited high surface area, NOx depletion, and improved adhesion for antibacterial coatings, making it suitable for water/soil remediation applications.

Summary: Engineering thermoplastics, such as poly(arylene ether sulfone), are commonly synthesized using fluorine-containing monomers. However, this study found that the reactivity was improved when chlorine atoms were used instead of fluorine atoms. The copolymers synthesized with chlorine-containing monomers showed slightly higher solution viscosity and mechanical strength compared to those synthesized with fluorine-containing monomers. Despite this difference, there were no significant variations in the structural, elemental, and chemical properties of the copolymers.

Summary: We investigate the interface properties between WSi2N4 and Mo2B, O-modified Mo2B, and OH-modified Mo2B nanosheets. We find that WSi2N4 and Mo2B form n-type Schottky contacts, while functionalizing Mo2B with O and OH leads to the formation of both n-type and p-type ohmic contacts with WSi2N4. Additionally, we demonstrate the emergence of quasi-ohmic contact with ultralow lateral Schottky barrier and zero vertical interfacial tunneling barriers in Mo2B(OH)2-contacted WSi2N4.

Summary: When rare-earth ions are embedded in a ferroelectric material, their photoluminescence can serve as an all-optical probe for temperature, electric field, and mechanical stimulus. However, the impact of ferroelectric phase transitions on photoluminescence is not well understood. In this study, we demonstrate changes in the photoluminescence of green emission bands during critical ferroelectric transitions in an Er-doped BaTiO3 material. We also find that the intensity ratio and wavelength position difference of sub-peaks provide information on the phase transitions.

The compound exhibits a high ferromagnetic transition temperature, making it excellent for room temperature applications. The nearly temperature-independent resistivity, conductivity, and carrier concentration of the compound, adherence to the Slater-Pauling rule, and the high intrinsic anomalous Hall conductivity achieved through hole doping further confirm its spin-gapless semiconductor nature. Additionally, the compound's SGS and topological properties make it suitable for spintronics and magneto-electronics devices.
