Summary: Novel renewable biomass-based cellulose-AONS dielectric composites were prepared by dissolving cellulose in NaOH/urea solution and using hydrothermally synthesized Al2O3 nanosheets as fillers. The addition of two-dimensional AONS significantly improved the dielectric constant and breakdown strength, achieving an energy density of 6.2 J/cm3 for the composite film with 5 wt% AONS content. Moreover, the introduction of hydrophobic PVDF further enhanced the dielectric energy storage properties, with a storage density of 8.32 J/cm3 and more than 10,000 cycles under 200 MV/m.

Summary: PVDF membranes blended with different amounts of MWCNT-ZnO nanocomposites were prepared, and their structural and morphological properties were investigated. The hydrophilicity of the membrane increased with the increase of nanocomposite content, as shown by the reduced contact angle. Blending 0.5% of MWCNT-ZnO in a PVDF membrane achieved 85% removal rate of RbB under UV light irradiation. The pollutant removal occurred through the processes of adsorption and photocatalysis, improving the membrane's self-cleaning property and lifetime.

Summary: This study demonstrates the effectiveness of a thin silica shell overcoating on Ag3PO4 nanoparticles in improving their photocatalytic activity and stability for repeated cycles of dye degradation. The silica-coated Ag3PO4 nanoparticles exhibited retained photocatalytic activity even after five cycles, while the bare Ag3PO4 nanoparticles showed a significant decline in activity. The findings suggest that the design of core-shell semiconductor nanostructures can provide insights into the development of reusable photocatalytic materials.

Summary: Surface-enhanced Raman spectroscopy (SERS) is a powerful tool in biophysics, bioanalytical chemistry, and biomedicine for monitoring extracellular chemical activity. However, the limited choice of SERS nanotags has hindered its practical application. This study repurposes fluorescent chemosensors as SERS nanotags, using a plasmon-induced reaction to immobilize them onto plasmonic nanostructures. The results demonstrate the successful immobilization and functionality of xanthene-based chemosensors as SERS chemosensors.
