Summary: A new bioadsorbent was proposed in this study using Luffa cylindrica and cross-linked chitosan for efficient removal of Allura red from aqueous solutions. The biosorbent showed highly efficient functional groups and morphology favorable for adsorption. The results regarding the adsorptive potential of the biosponge were supported by the degree of swelling and degree of crosslinking evaluations.

Summary: The study focused on preparing activated biochar from Luffa cylindrica fruits and found that sulfuric acid-treated biochar exhibited higher efficiency in 4NP adsorption. Additionally, the increase in surface area, pore filling, and hydrogen bonding were identified as important factors contributing to the high adsorption performance of the biochars.

Summary: In this study, cetylpyridinium bromide functionalized ZIF-8 (CPB@ZIF-8) was synthesized by post-synthetic modification strategy using methyl orange (MO) as the target dye. The introduction of CPB molecules into ZIF-8 greatly enhanced the adsorption performance of MO due to the incorporation of more positively charged sites, hydrophobic sites and aromatic rings in CPB-modified ZIF-8 frameworks. The prepared CPB@ZIF-8 composite showed a higher adsorption capacity for anionic dyes compared to pure ZIF-8 and other reported absorbents.

Summary: Enzymatic browning is a significant problem in the storage, processing, and transportation of Luffa cylindrica, reducing its commercial value. This study found that 1% CaCl2 treatment effectively reduced the surface browning of fresh-cut luffa, leading to higher total phenolic content and lower accumulation of malondialdehyde and hydrogen peroxide. The calcium treatment also increased the activities of superoxide dismutase, catalase, and phenylalanine ammonia lyase while inhibiting polyphenol oxidase activity. Gene expression analysis suggested that Ca2+ regulated the activities of these enzymes to inhibit browning. Additionally, the treated luffa maintained cell membrane and organelle integrity, potentially due to Ca2+ acting as a second messenger to reduce oxidative damage. These findings provide insights for breeding new luffa varieties resistant to browning and developing post-harvest treatments to reduce browning of luffa tissue.

Summary: The study investigated the use of Luffa cylindrica as a material to immobilize crosslinked chitosan for the removal of FR17 dye from aqueous solutions. LC/CS/GLUT and LC/CS/EPIC showed suitable morphology for mass transfer and relevant functional groups for adsorption. LC/CS/GLUT exhibited a higher maximum adsorption capacity for FR17 dye.

Summary: The sorption efficiency of ultra-trace levels of polonium by Luffa Cylindrica biochar fibers in water and seawater samples was investigated. The pH value greatly affects the sorption efficiency, and the Ag-coating of the surface improves the efficiency significantly. The modified adsorbent shows enhanced removal efficiency for polonium-contaminated waters, making it useful for treatment purposes.

Summary: We prepared a Luffa cylindrica/polypyrrole (LC/PPy) composite and investigated its application in the removal of tartrazine dye (E102) from water. Characterization techniques including FTIR, EDX, XRD, and SEM confirmed the thorough coating of PPy chains on the LC matrix, with the composite exhibiting amorphous and crystalline phases. We examined various parameters and found that the highest adsorption rate was achieved with a 30 min polymerization. The highest removal capacity was observed at pH 2.0, 298 K, and after 360 min of interaction. The composite showed potential for multiple adsorption-desorption cycles and also exhibited good results for the removal of other dyes.

Summary: Luffa Cylindrica, a dried fruit of a sponge-type plant, shows potential for replacing conventional porous composites due to its unique multi-porous structure. Impregnating Luffa Cylindrica with epoxy resin results in improved viscoelastic properties, with a 30% decrease in creep strain and compliance.

Summary: 3D naturally derived composites consisting of calcium alginate hydrogels and oxidized biochar obtained from Luffa cylindrica were synthesized for the removal of U(VI) from aqueous media. The composites showed high adsorption capacity and the formation of inner-sphere complexes. The adsorption process was endothermic and entropy-driven. These composites have potential use as effective adsorbents for the recovery of uranium ions.

Summary: This study investigated the selection of reference genes in luffa under various abiotic stresses using qRT-PCR analysis, and validated their stability. EF-1 alpha was identified as the most stable overall reference gene, while UBQ, and TUB were suitable for specific stress treatments. The reliability of the selected reference genes was confirmed by analyzing the expression of a target gene in luffa.

Summary: This study investigated the effectiveness of using Fe-based MOF or MIL-100(Fe) in conjunction with a PEDOT-modified Pt electrode for detecting the synthetic azo dye tartrazine. By modifying the electrode with two different methods, favorable lower reductive potentials, competitive sensitivities, and good repeatability and stability were achieved in all MIL-100(Fe)/PEDOT/Pt electrodes.
