A unique combination of cotton fabric (CF) with a mixture of EDTA and APTES Fe 3 O 4 magnetic particles was developed and utilized for the first time as an adsorbent for removing pollutants from wastewater. Initially, Fe 3 O 4 was synthesized using the co-precipitation method. Further, the surface of Fe 3 O 4 was modified by introducing amino functional groups through a reaction with APTES, resulting in Fe 3 O 4 -NH 2 . Following this, the surface of carbon fiber (CF) was altered using ethylenediaminetetraacetic acid (EDTA) to create CF@EDTA. Through the use of EDC-HCl and NHS, Fe 3 O 4 -NH 2 was attached to the surface of CF@EDTA, resulting in the final product CF@EDTA/Fe 3 O 4 . Subsequently, the prepared CF@EDTA/Fe 3 O 4 was utilized to adsorb metal pollutants from wastewater, with a thorough analysis conducted using various characterization techniques including FTIR, SEM, EDX , XRD , VSM , and XPS to study the materials. The study specifically aimed to assess the adsorption performance of our cotton-based material towards As(III) and Cr 3+ metal ions. The pH study was also performed. Results indicated that the material exhibited an adsorption capacity of approximately 714 mg/g for As(III) ions and 708 mg/g for Cr 3+ ions. The Langmuir and Freundlich models, as well as pseudo-first and second-order models were also analyzed. The Langmuir and pseudo-second-order models were found to best fit the data. In terms of regeneration and reusability, the materials showed straightforward regeneration and recyclability for up to 15 cycles. The remarkable adsorption capacity, combined with the unique blend of cotton and Fe 3 O 4 magnet, along with its recyclability, positions our material CF@EDTA/Fe 3 O 4 as a promising contender for wastewater treatment and other significant areas in water research.

Due to industrialization, soil heavy metal pollution is a growing concern, with humic substances (HS) playing a pivotal role in soil passivation. To address the long duration of the compost humification problem, coal fly ash (CFA) in situ catalyzes the rapid pyrolysis of the cotton stalk (CS) to produce HS to address Cd passivation. Results indicate that the highest yield of humic acid (HA) (8.42%) and fulvic acid (FA) (1.36%) is obtained when the CS to CFA mass ratio is 1:0.5, at 275 ℃ for 120 min. Further study reveals that CFA catalysis CS humification, through the creation of alkaline pyrolysis conditions, Fe 2 O 3 can stimulate the protein and the decomposition of hemicellulose in CS, and then, through the Maillard and Sugar-amine condensation reaction synthesis HA and FA. Applying HS-CS&CFA in Cd-contaminated soil demonstrates a 26.69% reduction in exchangeable Cd within 30 days by chemical complexation. Excellent maize growth effects and environmental benefits of HS products are the prerequisites for subsequent engineering applications. Similar industrial solid wastes, such as steel slag and red mud, rich in Fe 2 O 3 , can be explored to identify their catalytic humification effect. It could provide a novel and effective way for industrial solid wastes to be recycled for biomass humification and widely applied in remediating Cd-contaminated agricultural soil.

Plant bugs (Miridae species) have become major agricultural pests that cause increasing and severe economic damage. Plant-mediated RNA interference (RNAi) is emerging as an eco-friendly, efficient, and reliable strategy for pest management. In this study, we isolated and characterized a lethal gene of Apolygus lucorum and named it Apolygus lucorum LIM ( AlLIM ), which produced A. lucorum mortality rates ranging from 38% to 81%. Downregulation of the AlLIM gene expression in A. lucorum by injection of a double-stranded RNA (dsRNA) led to muscle structural disorganization that resulted in metamorphosis deficiency and increased mortality. Then we constructed a plant expression vector that enabled transgenic cotton to highly and stably express dsRNA of AlLIM ( dsAlLIM ) by Agrobacterium -mediated genetic transformation. In the field bioassay, dsAlLIM transgenic cotton was protected from A. lucorum damage with high efficiency, with almost no detectable yield loss. Therefore, our study successfully provides a promising genetically modified strategy to overpower A. lucorum attack.

Separation of oligosaccharides with a varied number of monosaccharides is an important issue in food chemistry. Raffinose, a functional oligosaccharide, has attracted increasing attentions due to its strong proliferative effect on bacteria. Industrially, cottonseed meal is an important resource for producing raffinose; however, raffinose extracted from the cottonseed meal contains a significant amount of sucrose that debases raffinose’s quality. In this work, an adsorptive separation of raffinose and sucrose on activated carbon was reported. Adsorption isotherms, adsorption kinetics and dynamic column adsorption–desorption were investigated. The activated carbon chosen has a significantly higher adsorption capacity of raffinose (0.60~0.65 g/g) than sucrose (0.35~0.40 g/g) at the equilibrium concentration studied (~35 g/L) and temperature from 293 K to 333 K. Adsorption isotherms and kinetics were fitted by the Freundlich isotherm model and the pseudo-second-order model, respectively. The effect of flow-rate and initial feed concentration on dynamic adsorption were investigated; meanwhile, the separation performance was further confirmed from dynamic desorption using aqueous ethanol of 20% as eluant. Remarkably, raffinose with purity over 90% and recovery of 79.2% could be obtained by the adsorption–desorption cycle using an aqueous feed solution containing 20 g/L of raffinose and 6 g/L of sucrose.

The accumulation and autoxidation of residual oily soil from human sebum is regarded as a major reason for the aging and yellowing of clothing and household textiles. In this study, the yellowing degree of cotton fabrics soiled with human sebum components and aged under various environmental conditions (various temperatures, humidities and light intensities etc.) were investigated. The representative sebum components including olive oil, squalene, oleic acid and cottonseed oil were selected and their chemical changes were studied by FTIR analysis. The results showed that, olive oil, squalene, oleic acid and cottonseed oil could caused more significant fabric-yellowing than other components in human sebum, and the yellowing degree could become higher with increasing temperatures, humidities and/or light intensities of aging environments. The chemical structures of olive oil, squalene and oleic acid changed remarkably after aging treatment. The aging products contained hydroxyl groups and carbonyl groups, and the conjugated C=O group was considered to be the chemical species leading to the yellowing of sebum-soiled fabrics.

The cotton fabric is esterified with a carboxylic acid (4-azidobenzoic acid) having an azide group to obtain a cotton fabric with an azide group on the surface. Then, the hydrophobic group-containing substance (1-heptyne) was modified on the surface of the cotton fabric through click chemistry, and a cotton fabric with super-hydrophobic and super-lipophilic properties was prepared. Scanning electron microscope (SEM), Fourier transform infrared spectrometer (FTIR), thermogravimetric/differential thermal analyzer (TG), and contact angle measuring instrument were used to characterize the surface morphology and hydrophobicity of the cotton fabric. The effect of pore size on the efficiency of oil-water separation was explored. The results show that the prepared cotton fabric has super-hydrophobic and super-lipophilic properties with a contact angle of up to 154.1°, and it has been successfully applied to oil/water separation. Even for different oil/water mixtures, the separation efficiency was better than 94% on average. The large pore size is beneficial to improve the efficiency of oil-water separation.

The evolution of pest resistance to insecticidal proteins from Bacillus thuringiensis (Bt) restricts the sustainable application of transgenic Bt crops, and exploring other ecofriendly insecticides to efficiently suppress Bt-resistant populations is thus urgently needed. The plant secondary metabolite rutin possesses pest resistance effects and plays an important role in plant resistance to pests, but the effect of rutin on pink bollworms is unclear. We investigated the effects of rutin on two types (Bt-susceptible and Bt-resistant) of pink bollworms ( Pectinophora gossypiella ). Rutin had significant inhibitory effects on the growth, development, and oviposition of both Bt-susceptible and Bt-resistant strains. For both strains, rutin ingestion by larvae did not significantly affect larval survival at 7 days after treatment or egg hatching rate but significantly decreased pupation rate, eclosion rate, neonate-to-adult survival, pupal weight and eggs per female and significantly prolonged larval developmental periods, and the effect increased with increasing rutin content. The response to rutin ingestion was basically consistent between Bt-resistant and Bt-susceptible strains, indicating that the Bt-resistant strain did not exhibit cross-resistance to rutin. These results provide a reference basis for green control and resistance management of pink bollworms and may be used as a component of comprehensive management for this pest.

Bacterial adhesion to material surfaces can lead to biofilm formation, posing risks of pathogen infections and reducing the service life of materials. Consequently, developing cotton fabrics with resistance to bacterial adhesion holds significant promise for enhancing hygiene and durability. In this study, a kind of cotton fabric with hydrophobic and antibacterial adhesion properties was designed in order to inhibit biofilm growth. A multifunctional coating was applied directly to the cotton fabric surface using the pad-dry-cure technique, and the fabric was subsequently chlorinated to confer antibacterial characteristics. Hcotton-Cl exhibited a water contact angle of 146° in hydrophobic experiments and demonstrated effective resistance against dye and soil contamination in self-cleaning tests. According to the GB/T 20944.3-2008 test method, Hcotton-Cl exhibited potent antibacterial activity, capable of inactivating 1 × 10⁶ CFU·mL -1 of bacteria within 10 minutes. Moreover, the fabric showed robust anti-adhesion properties, significantly reducing the likelihood of bacterial colonization. Anti-biofilm assays further confirmed that Hcotton-Cl markedly diminished biofilm formation, even after enduring 50 washing cycles.

To characterize the metabolic disorders of dairy cows treated with gossypol, 12 dairy cows were assigned to either a control group or a treatment group that was fed 1000 mg of gossypol per kilogram of dry matter feed for 28 days. Milk quality was adversely affected, as both milk protein and lactose levels were significantly decreased in the gossypol-treated group (3.40% vs 3.16%, P = 0.044; 5.15% vs 4.91%, P = 0.027; respectively). Plasma samples revealed increases in alanine aminotransferase (P = 0.092), choline esterase (P = 0.02), and glutathione transferase (P = 0.0005) and decreases in glucose (P = 0.076) in the gossypol-treated group. Mass spectrometry based comparative metabolomic analyses showed reduced concentrations of the gluconeogenesis precursor l-glutamine (P = 0.047), with significant decreases (P < 0.05) in plasma l-lysine, l-threonine, and homoserine levels after gossypol treatment. HDL-C and LDL-C levels in the gossypol-treated group were increased (P = 0.044) and decreased (P = 0.023), respectively. These results demonstrate that gossypol induced oxidative stress and hepatotoxicity; reduced peripheral lipid metabolism, and enhanced hepatic lipid accumulation; decreased amino acid bioavailability and milk protein synthesis; and decreased gluconeogenesis and milk lactose in dairy cows.

A new halogen-free and formaldehyde-free ammonium salt of melamine hexa(methylphosphonic acid) (AMHMPA) was facilely synthesized as flame retardant (FR) material under water-solvent and low temperature condition to counter inflammable cotton fabric fire hazard. The reactive P O(NH 4 ) 2 and PO(OH) 2 groups from AMHMPA reacted with cotton reactive OH groups to form P O C bonds. A layer of AMHMPA was coated onto the treated-cotton surface, and a carbon skeleton was formed after combustion. The char residue percentages of the treated-cotton fabrics and untreated fabric were 38.5 and 3.6% at 600 °C, respectively. The phosphorus contents for the control, treated-cotton and burned-cotton were 0, 37.499 and 24.896%, respectively. The LOIs of cotton treated with 30–90 g/L AMHMPA reached 32.0–43.0%. After 50 laundering cycles (LCs), the LOIs still maintained 26.0–33.4%. AMHMPA-treated cotton had no cytotoxicity towards the environment and humans. These results demonstrated that AMHMPA-treated cotton exhibited eco-friendly, outstanding durability and excellent flame retardancy. TG-IR and cone calorimeter results confirmed AMHMPA condensation phase flame retardant mechanism.

BACKGROUND Insects use odor detection to sense their surroundings. Use of volatile compounds, such as essential oils (EOs) of plants, to repel pests and disrupt their olfaction-driven behaviors has great practical potential for use in integrated pest management. Despite the available information on the repellent effects of EOs on herbivorous insects, the olfaction-based mechanisms remain unknown. RESULTS Y-tube olfactometer tests showed that the EOs of three Lamiaceae plants – Mentha arvensis L., Mentha piperita L. and Lavandula angustifolia Mill. – were significantly repellent to winged cotton aphid, Aphis gossypii Glover. Electrical penetration graph (EPG) tests indicated the EOs reduced phloem feeding and increased the level of non-productive probing by the aphids. The EOs also reduced the fecundity of winged Aphis gossypii . Electrophysiological bioassays and gas chromatography–mass spectrometry (GC–MS) identified five physiologically active volatiles, that is menthone, isomenthone, neomenthol and menthol from Mentha piperita ; menthone and menthol from Mentha arvensis ; and linalool from L. angustifolia . Behavioral tests confirmed that all five compounds repelled winged Aphis gossypii . Under field conditions, the growth rate of aphid populations after 7 days was significantly lower in fields treated with these compounds than in the control fields. CONCLUSION Our findings demonstrated that three EOs not only repelled winged Aphis gossypii but also interfered with the aphid's feeding behavior and reduced its fecundity. These EOs and their active constituents have great potential as eco-friendly control products for use against Aphis gossypii . The effects of these EOs also exceed other repellents that only keep pests away from host plants. © 2024 Society of Chemical Industry.

Polyester-cotton fabrics (PTCO) have excellent properties and are ubiquitous in daily life, but their serious flammability brings great safety hazards to people's lives. This study used phenylphosphonic acid (PPOA) and urea as raw materials to prepare a flame retardant named POU. PTCO/POU was prepared by the pad-dry-cure technique, and the performance was compared with that of PTCO/PPOA, revealing many interesting phenomena. Based on the gas phase and condensed phase flame-retardant mechanism brought by P/N synergy, PTCO/POU had better flame retardancy than PTCO/PPOA did. The damaged length was 6.7 cm, and the limiting oxygen index (LOI) value was 30.1%. The char residues after burning were complete and denser with a higher degree of graphitization. Thermogravimetric analysis showed that POU can significantly reduce the R max of PTCO, and improve its thermal stability in high temperature zones. The CCT results showed that PTCO/POU had the longest time to ignition and the smallest fire growth index, which was of great significance for reducing fire risk. The TG-FTIR results showed that the volatile products of PTCO/POU were greatly reduced, and during the burning process, NH 3 was produced to dilute the concentration of combustible gases. In addition, PTCO/POU also had better whiteness performance than PTCO/PPOA did. This work greatly improved the flame retardancy of PTCO in a simple way and expanded its application prospects.
