Summary: In this study, thermally activated kaolinite clay was used as an effective material for dye removal applications, producing reactive silica species. Multinuclear NMR studies revealed the presence of a short-range network of Al sites coordinated with IV, V, and VI, and mainly Si(Q4(1Al)). Critical parameters for methylene blue (MB) removal were determined using Plackett-Burman Design (PBD). Response Surface Methodology optimization resulted in a 90% removal rate. The kinetics and thermodynamics of the adsorption process were studied and fit into different models, showing chemisorption and a pseudo-second-order reaction, with a thermodynamically spontaneous and endothermic process. X-ray photoelectron spectroscopy (XPS) showed the involvement of Si, Al, O, Ca, Na, and N in the adsorption process. Regeneration of the adsorbent without loss of efficiency was achieved through thermal treatment.

Summary: In the past decades, the excessive use of chemical pesticides for crop protection has had negative effects on the environment and does not align with the goals of sustainable agriculture. Green nanotechnology offers a proactive solution for preventing and controlling plant diseases. This review focuses on the application of biogenic nanoparticles for early diagnosis and treatment of diseases in plants. It was observed that biogenic nanoparticles improve the selectivity, efficiency, and sensitivity of various methods such as DNA-based biosensing, colorimetric tests, lateral flow assays, and immunosensing. Among these methods, pocket-sized test kits based on lateral flow assays combined with biogenic nanoparticles can be an effective and convenient tool for screening potential food plant pathogens. Biogenic nanoparticles also contribute to the control of plant pathogens and show promising prospects in antimicrobial food packaging, postharvest technologies, environmental mitigation, and soil amendment.

Summary: Antibacterial packaging films were prepared using poly (vinyl alcohol) (PVOH), agarose, and cinnamon oil (CO). The films' mechanical, antibacterial, water- and UV-barrier properties were fully characterized. The addition of CO slightly affected the color of the films, but the dispersibility of CO in the polymeric matrix was influenced by its concentration. The UV-barrier property of PVOH/agarose was improved with the addition of a small amount of CO. The tensile strength of the films remained unchanged with increasing CO content, while the flexibility significantly decreased. The PVOH/agarose film with 1.5% (v/v) CO showed strong inhibition against Pseudomonas aeruginosa, Escherichia coli, Salmonella typhimurium, and Staphylococcus aureus due to the presence of cinnamaldehyde in CO, and this inhibitory capability was maintained for up to 7 days. Moreover, the PVOH/agarose film with 1% (v/v) CO was effective in enhancing the storability of bread slices during 50-day storage at room temperature.
