Summary: A transparent superhydrophobic organic-inorganic composite coating was prepared to protect ancient bricks from micro-organisms and weathering. The composite coating, consisting of fluorinated B72 and methyl-modified silica/titania, demonstrated enhanced performance against weathering, bacteria, and algae. By coating the bricks with the composite, the weathering process can be slowed without altering the bricks' outward appearance, providing a non-destructive way to protect ancient buildings.

Summary: Chitosan-functionalized nanosilica was electrosprayed on a spin-coated base layer to form a composite coating with a micro-nano protruding surface, showing good antibacterial properties and sustained release effect. Nanosilica with uniform size was prepared by sol-gel method and coated with quaternized chitosan. The composite coating exhibited a unique micro-nano surface structure and the contact sterilization of chitosan quaternary ammonium salt played a synergistic effect, resulting in good sterilization effect on drug-resistant Staphylococcus aureus and controlled sustained release of quaternized chitosan.

Summary: Biocompatible chitosan and chitosan/silica hybrid coatings were prepared to enhance the biocompatibility and corrosion resistance of biodegradable AZ31 Mg alloy. The optimized coatings showed high corrosion resistance and the chitosan/silica hybrid coating had a small globular rough structure. The presence of functional groups was confirmed by ATR-IR, and the chemical states were examined by XPS studies. The coated samples exhibited a dense layer of coral-like structure and less stoichiometric ratio of calcium-deficient apatite in Earle's solution. In-vitro cell culture studies showed good cell proliferation and the Ch-3/Si coating was non-hemolytic. Bacterial studies demonstrated the inherent antibacterial activity of the Ch-3/Si coating.

Summary: Flexible coating materials have been developed for the functionalization of biomedical devices. In this study, a cationic coating material called AQTA was constructed and used to functionalize medical devices for antibacterial and hemostatic applications. Stable AQTA coatings with tunable contents were easily achieved using a one-step soaking process. The high-content AQTA coating showed high blood compatibility and antibacterial ability on a polyurethane substrate. The hemostatic ability of AQTA was confirmed by improved properties of functionalized alginate dressing and gauze. The hemostatic mechanism of AQTA for negatively charged dressings was found to be optimized surface-activated platelet adhesion.

Summary: A novel organic-inorganic nanohybrid resin was synthesized through a sol-gel process using nano magnesium oxide and specially designed acrylic resin. The uniqueness of this process lies in the incorporation and dispersion of nano magnesium oxide into the acrylic resin matrix where it functions as a component. Magnesium oxide nanoparticles were successfully synthesized using magnesium nitrate as a precursor. The synthesized nanoparticles and their distribution in the acrylic resin matrix were confirmed through spectroscopic, X-ray diffraction, and SEM analysis. Coatings based on this hybrid resin demonstrated excellent antimicrobial activity, making it a potential candidate for antimicrobial coating applications.

Summary: Hydrophobic fumed silica (HFS) was investigated for its dispersion technology in this study. The size and structure of HFS primary particles were observed using transmission electron microscopy (TEM). The particle size and dispersion performance of HFS were tested using dynamic light scattering (DLS), while the elemental distribution of the coatings was characterized using energy dispersive spectroscopy (EDS). The results showed that HFS in a non-ionic polymer dispersant exhibited the best dispersion performance, and the particle size of HFS in the aqueous dispersion was influenced by dispersion conditions. Under optimized conditions, a HFS aqueous dispersion with a particle size of D50 = 27.2 nm could be prepared, and it showed stable storage stability even after 47 days.

Summary: The long-term and indiscriminate use of synthetic pesticides to mitigate plant pathogens has created serious issues of water health, soil contamination, non-target organisms, resistant species, and environmental and human health hazards. To reduce dependency on synthetic chemicals, scientists have developed alternative plant disease management strategies, with biological agents and resistance elicitors being the most important alternatives in the past two decades. Silica-based materials/chitosan with a dual mode of action have shown promise as alternatives to prevent plant diseases through direct and indirect mechanisms.

Summary: Four novel bis-chalcone-based carbazole derivative photoinitiators were designed and synthesized in this study. Their maximum absorption wavelengths were determined and found to exhibit high molar extinction coefficients. Furthermore, a three-component photoinitiation system including bis-chalcone/iodonium/amine was successfully used to trigger the rapid and efficient photopolymerization of acrylates. The photoinitiators also showed good photo bleaching and biocompatibility, making them suitable for applications such as 3D printing and deep coating curing.
