Summary: In this study, hydroxyapatite nanofibers were introduced as fillers to enhance the bioactivity of poly(lactic acid) (PLA) for potential use in spinal implant materials. The composites showed improved tensile and flexural strength compared to PLA resin, with even higher performance observed for composites with higher aspect ratio HANF and PLA grafted HANF. The bioactivity test revealed that composites with HANF and HANF-g-PLA had higher apatite growth rate and uniformity, suggesting their potential application in the field of spinal implant materials.

Summary: In this study, dye-doped polymer-dispersed liquid crystalline (DDPDLC) films were prepared with high mechanical properties and low driving voltage by doping different dichroic anthraquinone dyes. The effects of various dye and doping concentrations on microscopic morphology, electro-optical characteristics, and mechanical characteristics were investigated. The optimal doping concentrations of different dyes were also explored. Electrochromic PDLC films have been prepared based on the research results of dye content. The mechanical properties, electro-optical properties and microstructures of the films have been studied. The research provides a theoretical basis for obtaining PDLC films with a wider color gamut and supports the practical application of visible light camouflage technology in the military.

Summary: This paper investigates the impact of reprocessing on the rheological and mechanical properties of a biocomposite. The results reveal that increasing the number of extrusions leads to a decrease in viscosity and molecular weight of the matrix and biocomposite. Additionally, the mechanical properties, such as tensile strength and elongation, decrease with the number of extrusions for the matrix, while the biocomposite shows a temporary increase in these properties after the first extrusion, followed by a slight decrease but still higher values compared to the virgin biocomposite.

Summary: Chemical mechanical polishing (CMP) is used to achieve planarization in copper interconnect fabrication. In this study, polyacrylic acid (PAA) was used as a lubricant and complement to 1,2,4-triazole for copper CMP. The addition of PAA led to an ultra-smooth copper surface with 1 nm roughness and a relatively uniform surface film. PAA served as an effective lubricant and complemented 1,2,4-triazole to improve the copper surface quality.

Summary: In this study, the stabilization of a nematic liquid crystal using chiral amino acid-based polymers is reported. The effect of molecular weight of structurally similar polymers on the physical parameters of polymer-stabilized liquid crystals (PSLCs) is investigated for the first time. By varying the molecular weight of the polymers, the size of the self-assembled network in the liquid crystal can be adjusted, thereby altering the dielectric, electrical, electro-optic, and optical properties. This method presents several possibilities for fabricating optoelectronic devices.

Summary: In this study, a fluoride-free triblock copolymer poly(styrene-b-butadiene-b-styrene) (SBS) fibrous membrane was prepared using electrospinning. A coarse structure was built onto the surface of the SBS fiber using dip-coating of silicon dioxide nanoparticles (SiO2 NPs) based on the bionics of lotus leaves. Polydopamine was introduced as an interfacial adhesive between the SBS fiber and SiO2 NPs. The modified nanofibrous membrane exhibited significantly improved hydrophobicity and retained super-hydrophobic properties after stretching cycles.

The platform consists of a plasma oxazoline-coated polyvinyl chloride (POx-PVC) film with tough hydrogel covalently bound to its surface and a reactor tube for reactions. The hydrogel arrays on the film provide a strong matrix for entrapping biomolecules and tolerate shear stress, resulting in a >6-fold increase in reaction rate.

Summary: Pacific oysters are important in aquaculture, and this study investigated how to improve larval cryopreservation techniques. The results showed that adding the lipid POPC to the base CPA significantly increased larval development after thawing. Adding tocopherol alone had no significant effect. However, combining POPC and tocopherol improved survival rates and doubled the spat production compared to the base CPA.

Summary: This study developed phase-change thermoregulated nanofiber membranes using polyethylene glycol (PCM) as the phase change material and polyacrylonitrile (PAN) as the polymer backbone, with increased thermal conductivity by adding spherical nano-alumina (Al2O3) through coaxial electrospinning technology. The membranes exhibited excellent thermal responsiveness and thermoregulation when 5% Al2O3 was added. They had a high melting enthalpy of 60.05 J·g(-1) and retained a high enthalpy after 50 cycles of cold and heat, withstanding sudden changes in ambient temperature well. Additionally, the nanofiber membranes had good air and moisture permeability, enhancing wearer comfort. Therefore, they can be considered as a promising textile for personal thermal management.

Summary: In this study, the effects of three different dopants (Mg, Sr, and Ba) on the structure of C-S-H-tobermorite were investigated using DFT calculations. The results showed that Mg doping led to a decrease in lattice volume and significant changes in the structure and coordination of magnesium-oxygen polyhedra. On the other hand, Sr and Ba doping only increased the volume of the respective oxygen polyhedra. Despite distorting the structure, Mg doping improved the compressive and shear resistance of tobermorillonite, while having less effect on the anisotropy of the Young's modulus. The findings suggest that Mg doping is a promising approach for optimizing the structural design of C-S-H.

Summary: In this study, a simple strategy was developed to enable molecules with near-infrared II (NIR-II) imaging and photothermal therapy (PTT)/photodynamic therapy (PDT) abilities by equipping NIR-II aggregation-induced emission luminogens (AIEgens) with the cationic trimethylammonium unit, named as TDTN+. The resulting TDTN+ species could self-assemble into nanoparticles, exhibiting a maximum emission at approximately 1052 nm, high photothermal conversion efficiency (66.7%), type I and type II ROS generation, and mitochondria-targeting ability. TDTN+ enabled bright fluorescence brain imaging and effective tumor killing. Overall, this work presents an innovative design strategy for developing multimodality phototheranostic agents.
