Summary: Researchers have developed a simple and effective method to make plastic surfaces hydrophilic/oleophobic by coating them with a perfluoropolyether and irradiating them with UV/Ozone. The treated plastics exhibit both hydrophilicity and oleophobicity, as confirmed by contact angle measurements and FTIR results. These functionalized plastics show superior antifogging performance and detergent-free cleaning capability, and do not degrade in aging tests.

Summary: This paper presents a method for synthesizing a fluorine-containing coating with hydrophobic and oleophobic properties and studies its performance. By modifying epoxy resin and introducing fluorine, the epoxy resin is further modified through chemical reactions such as ring opening, esterification, and neutralization, using acrylic acid, maleic anhydride, and organic base as raw materials. The effects of the amount of fluorine monomer on the properties of the synthetic coating were characterized and discussed. The results showed that the synthesized coating exhibited good hydrophobic and oleophobic properties.

Summary: The hydrophobic block copolymer PCL-b-PFPE was successfully synthesised by reacting PFPE-COOH with PCL. The surface morphology of the microspheres was influenced by the solvent and ambient humidity, with chloroform forming smooth microspheres and DMF/CF mixed solvent producing a 'pit' surface morphology. The introduction of PFPE chain into PCL enhanced the hydrophobicity of coatings, providing super-hydrophobicity to the finished polyester fabric.

Summary: This paper reports the effect of silver doping on the interaction between a silica-based bioactive glass and albumin and fibronectin. The presence of silver significantly increases the adsorption of albumin and fibronectin and leads to a higher loss of secondary structure. It is also observed that proteins are embedded inside the surface reaction layer during adsorption due to the formation of a hydrated silica gel layer.

Summary: We conducted the first comprehensive characterization of the structural and photoluminescence properties of optically active centers formed through implantation of Mg+ ions in synthetic diamond. Using electron emission channeling technique, we analyzed the structural configurations of Mg-related defects and observed a major fraction of Mg atoms (around 30% to 42%) in sites consistent with the split-vacancy structure of the MgV complex. Photoluminescence emission studies revealed new spectral features and provided insights into the optimal conditions for stable and intense emission. Our findings have significant implications for quantum information processing applications utilizing the tunable properties of the MgV center.
