Summary: Removing organic pollutants, textile dyes, and pharmaceutical wastes from water bodies is crucial for a safe environment. This study developed semiconductor zinc oxide nanoparticles (ZnO NPs) and plasmonic Ag-supported ZnO nanocomposites (ZnO-Ag) using a bio-approach as an alternative to hazardous synthesis methods. The ZnO-Ag nanocomposite exhibited enhanced photocatalytic activity for the degradation of methylene blue (MB) dye due to the presence of plasmonic Ag NPs and the surface plasmon resonance (SPR) effect. The research provides valuable insights for the future application of noble metal-modified nanocatalysts in water treatment.

Summary: ZnO nanomaterials with stereochemical structure have attracted attention in photocatalytic materials research, but their sensitivity to UV light restricts their application; composites of ZnO with other nanomaterials can enhance photocatalytic activity. TiO2/ZnO cube nanocomposites and Ag/ZnO hollow spheres were successfully synthesized via hydrothermal reaction and chemical deposition, respectively, with the Ag/ZnO hollow spheres showing higher RhB degradation activity under visible light.

Summary: This paper investigates the possibility of producing nanocomposites of chitosan incorporated with bioactive compound-modified ZnO nanoparticles (NP). ZnO nanoparticles were synthesized using a biogenic method, and curcumin (CRC) was anchored onto their surface. Chitosan-based ZnO-CRC nanocomposites were prepared through an ex-situ method that involved separate preparation of ZnO particles and their dispersion in the chitosan matrix by mechanical and ultrasonic mixing. The synthesized samples were characterized using X-ray diffraction, SEM microscopy, FTIR and EDX spectroscopy, as well as contact angle measurements. The results demonstrate that the synthesized materials have suitable morpho-structural and wetting characteristics for application in biotechnological coating systems.

Summary: This study utilized carboxylic acid-based deep eutectic solvents for pretreating cellulose, resulting in the production of cellulose nanofibers with widths less than 100 nm through simultaneous esterification modifications. Esterification modifications prevented over-hydrolysis and dissolution of cellulose while maintaining the cellulose I crystal structure. The esterified cellulose nanofibers showed improved dispersibility and interfacial compatibility with polylactic acid, leading to mechanical enhancement of CNF/PLA composites.

Summary: The paper proposes a novel deep learning-based prediction framework, aTCN-LSTM, for accurate cooling load predictions. The framework utilizes a gate-controlled multi-head temporal convolutional network and a sparse probabilistic self-attention mechanism with a bidirectional long short-term memory network to capture both temporal and long-term dependencies in the cooling load sequences. Experimental results demonstrate the effectiveness and superiority of the proposed method, which can serve as an effective guide for HVAC chiller scheduling and demand management initiatives.
