Summary: The purpose of this study was to develop a novel approach for designing multifunctional technical cotton textiles by coating them with smart bio-materials. Two different ternary nanocomposites were prepared and applied to cotton fibers to provide antimicrobial and ultraviolet protection characteristics. The study found that the ZnO-rich nanocomposite showed better antimicrobial and ultraviolet protection performance compared to the TiO2-rich nanocomposite. The results demonstrate the potential of these coated cotton fabrics for various applications.

Summary: In this study, a sustainable flame retardant and superhydrophobic cotton fabric was prepared using chitosan and sodium polyborate treatment, followed by PDMS treatment. The fabric demonstrated enhanced flame retardancy and superhydrophobic properties, as well as anti-sticking, self-cleaning, and oil/water-separating capabilities. This coating method, free from F, Cl, Br, and P elements, is considered a clean approach for producing functional cotton fabrics.

Summary: TiO2+Pt plasmonic solids with 1 wt% Pt and different TiO2 supports (anatase nanoparticles (TNP), polycrystalline nanorods (a-TNR) and single-crystal anatase nanorods (TNR)) were synthesized and tested as photo, thermal and photothermal catalysts. The formation of Pt particles with different sizes, crystallinities and degrees of interaction with the TiO2 supports was influenced by the charges of the TiO2 support surfaces. The TNR+Pt catalyst showed low visible-light-triggered photocatalytic activity but exhibited the highest photothermal catalytic H2-assisted NO2 reduction rate.

Summary: This study successfully synthesized various types of thiolated-graphene quantum dots (GQDs) and utilized them in a one-droplet microfluidic paper-based analytical device for the simultaneous multi-sensing of heavy metal ions. The GQDs were functionalized and stabilized on the surface of hydrophobic fiber-glass, enabling colorimetric chemosensing of ions including iron, copper, cobalt, mercury, chrome, manganese, and nickel. The results were confirmed using fluorescence spectrometry, and the platform showed potential for facile metal ion detection in human urine models and environmental fluids.

Summary: Laboratory illumination is strong enough to create a photostationary state (PSS) of amphiphilic azo-benzene compounds in water. The [cis]PSS/[trans]PSS ratios were observed to be 0.33-1.2 in D2O and 0.37-3.8 in dimethyl sulfoxide-d6. ortho-Fluoroazobenzene amphiphiles show higher cis-isomer concentration at equilibrium compared to non-fluorinated compounds due to differences in optical absorption profiles. The kinetics of isomerization were measured using UV-Vis spectroscopy and the ratio of trans-to-cis rates does not directly correlate with the observed PSS. The half-life for PSS formation is 40 minutes for fluorinated compounds and 80 minutes for non-fluorinated compounds.

Summary: This study designed an integrated structure of Cu2O@Au/Cu2O heterostructure particles, which achieved significantly enhanced photocatalytic performance by simultaneously considering the integrated structural characteristics and localized surface plasmon resonance (LSPR) effect. Experimental characterization and theoretical simulation confirmed the three-in-one synergy of the integrated heterostructure, including the LSPR effect of Au nanoparticles, the light scattering based on core-shell heterostructure, and the effective charge separation based on inter-embedded heterostructure. The concept of integrated heterostructure cooperated with LSPR effect provides a new strategy for designing future catalysts.

Summary: In this study, the recombination of separated ion-radical states (SIRS) in PAPh films was analyzed, and it was found that the contribution of X-SIRS recombination to total luminescence varies with different environments. It was also shown that the recombination of labile SIRS is independent of the nature of the atmosphere. The study theoretically substantiated that SIRS recombination can occur via the transfer of both positive and negative charges, and the efficiency of thermal activation of recombination processes depends on the ratio of radiant and conductive channels of energy transfer.

Summary: Bifunctional hybrids containing photochromic indolyl(thienyl) diarylethenes and an ionochromic rhodamine moiety connected by a dimethylene spacer were synthesized. These hybrids exhibit absorption at 450-455 nm and fluorescence at 560 nm in toluene. UV light triggers ring-closed non-fluorescent diarylethene formation, which can be reversed under visible light or in the dark. In the presence of H+ cation, a naked eye effect is observed with the opening of the rhodamine-spirolactam ring and a pink-crimson coloration at 561 nm accompanied by intense long-wavelength emission at 586 nm. This process is reversible by exposure to triethylamine, as confirmed by NMR experiments. The light-induced isomerizations and proton-induced transformations were explained using computational methods. Reversible switching of fluorescent properties can be achieved by light irradiation and proton.
