Summary: In this work, a novel silicon-containing intumescent flame retardant (LK) was developed by grafting gamma-aminopropyltriethoxysilane (APTES) onto self-assembled lignin-based flame retardant (LMA). The obtained LK was applied on polypropylene (PP) to obtain flame retardant PP (PP-LK). Additionally, low cost flame retardant PP biocomposite (PP/M/L) with high lignin content was prepared by compounding lignin, LK and PP. The developed PP-LK and PP/M/L exhibited excellent flame retardancy, smoke suppression and mechanical properties.

Summary: The study established the influence of the crystalline phase and agglomeration degree of TiO2 nanoparticles on photocatalytic hydroxyl radical formation and bacterial inactivation in TiO2/SiO2 composite coatings. A relationship between hydroxyl radicals' formation and charge carrier transfer mechanism between defect levels in SiO2 and TiO2 embedded nanoparticles was established through a simple spectroscopic method. This correlation complements the lack of mechanisms behind the photocatalytic activity in TiO2/SiO2 composites.

Summary: This study synthesized methylene bisacrylamide (MBA) crosslinked cellulose-kaolin (CMK) composite hydrogels and investigated their internal structures and combustion behavior. The results showed that the addition of kaolin improved the fire retardancy of hydrogels but reduced their swelling ability. The hydrogel with a cellulose to MBA ratio of 1:2 and 2% w/v kaolin exhibited the lowest heat release rate and total heat release, and the cotton fabric coated with this hydrogel showed a significant increase in limiting oxygen index. The kinetic analysis confirmed the increased LOI after kaolin addition, and VFT and OFT validated the delay in the burning process and the formation of a protective char layer.

Summary: In this study, the fire resistance of flax fibre composites produced with a polyurethane-based shape memory polymer matrix was improved by incorporating diammonium phosphate, polydopamine, and titanium dioxide. The treated composites exhibited a protective char layer, which preserved the integrity after combustion and reduced mass loss. Additionally, the incorporation of polydopamine and titanium dioxide resulted in improved fire resistance, as evidenced by increased limiting oxygen index values and decreased flame propagation rate.

Summary: This study compares two processing techniques, chemical and physical, to repurpose chicken feathers into flame-retardant chicken fibres (FRCF) for enhancing the fire and mechanical performances of polypropylene (PP) composites. Repurposing chicken feathers helps reduce industrial waste and expensive waste management solutions. The suitable method of attaining FRCF is selected based on fire reaction and mechanical outcomes. PP composites with 44 wt% FRCF achieve a significant reduction in peak heat release rate and the chemically-treated fibre composites achieve a V-0 rating, demonstrating the impact of fibre processing techniques on composite performance.

Summary: This study investigates the effect of arsenic (As) contamination on tomato plants and the potential use of silicon nanoparticles (Si NPs) to mitigate this effect. The results show that higher concentrations of As in irrigation water lead to greater uptake and translocation of As in tomato plants. However, the application of Si NPs reduces As translocation and tomato yield. The increased production of photosynthetic pigments and improved enzymatic activity suggest that Si NPs can help tomato plants adapt to high concentrations of As.

Summary: This study evaluated the applications of drench (D) and foliar (F) ZnO nanoparticles (NZnO) compared to ionic Zn2+ (ZnSO4) in lettuce. Results showed that NZnO promoted increases in biomass (14-52%), chlorophylls (32-69%), and antioxidant compounds such as phenolics, flavonoids, and vitamin C compared to Zn2+. A better response was found in the plants with foliar applications of NZnO equivalent to 50-75% of the total Zn2+ applied conventionally. These findings demonstrate the potential of NZnO in improving fertilizer efficiency and the quality of lettuce.

Summary: This study aimed to evaluate the ability of different shapes of gold colloids to elevate the temperature of blood plasma and breast cancer-simulated fluid under laser stimulation. The light-to-heat efficiency of the gold particles depends on their shape, with star-shaped colloids showing a 36% higher efficiency compared to sphere-shaped colloids. However, the raised temperature of the surrounding medium is the lowest in star-shaped colloids. Attaching fluorescein and polyethylene glycol to gold spheres enhances their colloidal stability and light-to-heat efficiency, while maintaining their optical properties post-treatment.

Summary: The dispersion and compatibility of carbon nanoparticles (CNPs) in a polypropylene (PP) matrix were improved by modifying the CNPs using cold propylene plasma and mixing carbon nanofibers (CNFs) and graphene nanoplatelets (GNPs) with the PP matrix. This resulted in a nanocomposite with enhanced mechanical properties, where the use of mixtures improved the dispersion and hindered reagglomeration of CNPs, and the surface modification with plasma promoted higher compatibility between the phases.

Summary: The tomato crop is vulnerable to different types of stress, including the phytopathogen Fusarium oxysporum f. sp. lycopersici. Graphene-Cu nanocomposites have shown positive effects on tomato plants infected with Fusarium oxysporum, including delaying the incidence of vascular wilt disease, increasing photosynthetic pigments, and improving the antioxidant defense system. Furthermore, graphene functionalization enhances the effectiveness of the nanocomposites. The plants treated with the Graphene-Cu nanocomposite exhibited better responses to biotic stress in terms of water potential and the efficiency of photosystem II.
