Summary: Researchers constructed BaTiO3/TiO2@polypyrrole (PPy) composites with hollow multishelled structure (HoMS) to enhance the electromagnetic wave absorbing properties of BaTiO3-based absorbing material. BaTiO3/TiO2 HoMSs were prepared using TiO2 HoMSs as a template. FeCl3 was then introduced to initiate the oxidative polymerization of pyrrole monomer, successfully forming BaTiO3/TiO2@PPy HoMSs. The electromagnetic wave absorbing properties of BaTiO3/TiO2 HoMSs and BaTiO3/TiO2@PPy HoMSs with different shell numbers were investigated. The results show that BaTiO3/TiO2@PPy HoMSs exhibit improved microwave absorption, with tripled-shelled BaTiO3/TiO2@PPy HoMS having the most excellent absorbing performance.

Summary: A combination of hollow melanosomes and carbon black is proposed to mimic hollow melanosomes for the fabrication of amorphous photonic structures (APSs) and non-iridescent structural colors. The APSs show a wide range of structural colors and reflection peaks, which can be controlled by adjusting the diameters of hollow melanosomes, the amount of carbon black, and the mixing ratios. The APSs demonstrate high sensitivity in visual detection for chemicals with similar refractive indices and have potential applications in display, visual detection, information encryption, and anti-counterfeiting.

Summary: Freestanding membranes of CuCl2-implanted TpPa covalent organic frameworks (COFs) were produced using mechanochemical methods. These membranes exhibited high I2 adsorption capacity (566.78 gmol-1) in cyclohexane, with 2.2I2 per unit cell and 1.3I2 immobilized on 3Cl- ions (60%) and 0.9 on 3N atoms (40%). When placed in aqueous media, the membrane released 61.1% of its loaded I2 within 10 min, primarily from the Cl- ions, followed by the remaining 38.9% released mainly from the N atoms within about 5 h. The I2-loaded TpPa-CuCl2 COF membranes showed promising potential for instant and sustained disinfection, being able to repeatedly kill E. coli and retain bactericidal activity for several hours.

Summary: In this study, PVS-capped surfaces were constructed on PEMs via electrostatic assembly. The water wetting behavior on the resulting PVS-capped PEMs was meticulously studied. It was found that by adjusting the molecular packing density of surface sulfonate groups, the PVS capping promoted complete surface wetting by water and diminished the affinity to adhesion of ice, oil, and wax.

The resulting M2-SAM of Au@OLA NPs exhibit unconventional Moire ' patterns beyond the imaging limit of scanning electron microscopy. The mono-crystallinity enables the M2-SAM to be used as SERS substrates for quantitative analysis and fabricate high precision and broad measurement span temperature sensors.

Summary: Zero-dimensional (0D) metal halide perovskites (MHPs) have unique crystal and electronic structure. However, their luminescent efficiencies are lower than three-dimensional (3D) MHPs. This study synthesized Sn2+-doped 0D Rb4CdCl6 crystals with near-unity quantum efficiency (PLQY -98.04%) under UV excitation. The emission is attributed to self-trapped excitons, and Sn2+ dopant plays a vital role in improving the PLQY of 0D MHPs. These luminescent materials have promising applications in optoelectronic devices.

Summary: This study systematically investigated the role of sodium hydroxide in the formation and emission properties of Au nanoclusters. It was found that the activity of the gold precursor and the emission properties of the resulting Au nanoclusters depend on the addition time of sodium hydroxide. Additionally, the reducing ability of BSA is dependent on the concentration of sodium hydroxide in the reaction solution. By optimizing the addition time and concentration of sodium hydroxide used, Au nanoclusters with improved emission properties were successfully synthesized under relatively low BSA concentrations, showing improved performance in sensing Cu2+ ions.

Summary: This study developed a simple strategy of ternary co-assembling to facilitate narrowband circularly polarized luminescence (CPL) response from cyanine J-aggregates. The J-aggregate emitters were co-assembled as a shell of light harvester nanoparticles to form core-shell structures at the nanoscale. By taking advantage of core-shell energy transfer and chiral transfer, narrowband CPL response of TDBC-J was demonstrated with a dissymmetric factor glum of +/- 1 x 10-3. This work provides a simple approach to achieve narrowband CPL response from J-aggregates in an aqueous solution, with potential applications in the greatly red-shifted or near-infrared regime.

Summary: In this study, the excited-state proton transfer (ESPT) behavior between photoacids and silanols on mesostructured surfaces was investigated using steady and picosecond time-resolved fluorescence spectroscopy. It was found that deprotonated silanols acted as acceptors in ESPT, while protonated silanols affected ESPT by changing the basicity of the silica surface. The non-uniform distribution of Q(3)/Q(2) silanols on the surface led to heterogeneous properties, such as basicity, which greatly influenced the ESPT dynamics. This work provides new insights into the ESPT mechanism in mesostructured systems and inspiration for designing smart sensors and materials sensitive to proton concentration.

Summary: The electrochemical activity of Au nanoparticles (NPs) with varied sizes and shapes was analyzed based on cyclic voltammetry data deconvolution and density functional theory calculation. The study found that the defective {111} facets induced a large negative shift in electrode potential, the defective {100} facets caused a relatively large positive shift, and the defective {110} facets caused a small negative shift. The reducing activity of Au NPs increased with the surface fractions of defective {111} facets, which was mainly determined by the NP surface topographic features. Furthermore, the surface topography-induced electrocatalytic activity of Au NPs was demonstrated by using them as electrocatalysts for the oxygen reduction reaction (ORR).
