Flame-retardant cotton is of great importance in clothing, household goods and various industrial products. In this work, we report a synthesis of phosphorus-rich ammonium ethylenediamine tetramethylenephosphonate (AEDTMP) and its application to flame-retardant cotton fabrics. We synthesize AEDTMP in three step reactions using ethylenediamine, formaldehyde, phosphorous acid and ammonia and characterized through Fourier transform infrared (FTIR), nuclear magnetic resonance, and ultra-performance liquid chromatography-mass spectrometry analyses. The flame-retardant finishing of cotton is done by immerse-pressing fabrics in 5% AEDTMP and 5% trimethylol melamine (TMM) binder solution with increasing treating times to realize multilayer coating on the fabrics. Vertical flame tests show an enhancement of flame retardancy and durability of the treated cotton samples as increasing the treating times. Through FTIR, thermogravimetric, cone calorimetry, scanning electron microscopy image and energy-dispersive X-ray analyses, we reveal that the P–O–C and C–O–C bonds are newly formed by reactions between the fiber, AEDTMP flame retardant and TMM binder, and the multilayer coating enhances such binding reactions. We further performed the tests of mechanical properties, verifying that the 5-times treated sample has less effect on the comfort and air permeability of the cotton fabrics than the single-treated sample. Our work highlights that the multilayer coating with lower density AEDTMP is superior in flame retardancy, durability and mechanical properties of treated cotton. Graphical abstract

Covalently bonded metal-free electrocatalysts exhibit significant potential for sustainable energy technologies, yet their performances remain unsatisfactory compared with metal-based catalysts. Herein, we propose an all-organic electrocatalyst, MEC-2, that conforms to the infrequent oxide path mechanism in alkaline oxygen evolution reaction through post-oxidation modification. MEC-2 achieves an intrinsic overpotential of 257.7 ± 0.6 mV at 10 mA·cm −2 and possesses durability with negligible degradation over 100,000 CV cycles or 250 h of operation at 1.0 A·cm −2 , being comparable to the advanced metal-based OER electrocatalysts. The 18 O-labeled operando characterization and theoretical calculations unveil that post-oxidation modification enhances the electron affinity to OH intermediates, and adjusts the adsorption configuration and proximity distance of O intermediates, thereby promoting direct O−O radical coupling. In this work, we show a fresh perspective for understanding the role of non-metallic elements/functional groups in electrocatalysis, and to a certain extent, narrows the gap between all-organic electrocatalysts and metal-based electrocatalysts.

Hydrovoltaic technologies that generate electricity by absorbing or transferring free water without chemical reactions have been explored as potential candidates for renewable energy. Self-powered flexible sensors, including hydrovoltaic fibers, are becoming an important research direction in the field of renewable energy. However, integrating sensing and power generation in functional fibers remains challenging due to the need to regulate water movement to achieve performance differences. Here, we present a gas-liquid two-phase flow spinning method, inspired by spider multimodal spinning, that uses bubble-triggered spinning-liquid deformation to fabricate hollow, solid spindle, and ratchet tooth-shaped fibers. These structures alter water adsorption and transfer behaviors, making them suitable for targeted applications in hydrovoltaic devices for energy and sensing fields. Shaped fibers prepared from alginate-bridged MoS₂ enable a wide range of hydrovoltaic applications. The obtained fiber has a power density of 2.18 mW/cm 3 , stable operation at 2.1 V for 43 hours, and sensitivity of 9.36 mV/RH%/s, leading to the development of smart masks for nasal cycle monitoring, diagnosis, and therapy as potential applications. Spinning materials were extended to materials such as carboxymethyl cellulose, polyvinyl alcohol, etc., inspiring the design of structure-responsive hydroelectric materials and advancing textile electronics.

Thermal and mechanical properties of yttrium tantalate (YTaO 4 ), a top coat ceramic of thermal barrier coatings (TBCs) for aeroengines, are enhanced by synthesizing Y 1− x Ta 1− x M 2 x O 4 (M = Ti, Zr, Hf; x = 0.06, 0.12, 0.18, 0.24) medium-entropy ceramics (MECs) using a two-step sintering method. In addition, the thermal conductivity, thermal expansion coefficients (TECs), and fracture toughness of MECs were investigated. An X-ray diffraction study revealed that the Y 1− x Ta 1− x M 2 x O 4 MECs were monoclinic, and the Ti, Zr, and Hf doping elements replaced Y and Ta. The variations in atomic weights and ionic radii led to disturbed atomic arrangements and severe lattice distortions, resulting in improving the phonon scattering and reduced thermal conductivity, with Y 1− x Ta 1− x M 2 x O 4 MECs ( x = 0.24) exhibiting the lowest thermal conductivity of 1.23 W·m −1 ·K −1 at 900°C. The introduction of MO 2 increased the configurational entropy and weakened the ionic bonding energy, obtaining high TECs (10.4 × 10 −6 K −1 at 1400°C). The reduction in the monoclinic angle β lowered the ferroelastic domain inversion energy barrier. Moreover, microcracks and crack extension toughening endowed Y 1− x Ta 1− x M 2 x O 4 MECs ( x = 0.24) with the highest fracture toughness of (4.1 ± 0.5) MPa·m 1/2 . The simultaneous improvement of the thermal and mechanical properties of the MO 2 (M = Ti, Zr, Hf) co-doped YTaO 4 MECs can be extended to other materials.

It is highly desirable that artificial circularly polarized phosphorescent materials with high luminescence asymmetry factor ( g lum ), narrowband emission and tunable chiral phosphorescent performance can be constructed. Especially, precise control and simultaneous independent switching of circularly polarized fluorescent and phosphorescent performance for the same molecules remain a formidable challenge. Herein, we propose a strategy to customized design of circularly polarized phosphorescent materials based on large language models and transfer learning methods, which not only enables efficient identification of suitable synthesis precursors, but also provides valuable guidance for experimental procedures. We demonstrate the significant advantages of transfer learning with limited chemical data, and precisely fabricate films with high g lum (1.86), narrow full-width at half-maximum (49 nm) and customized circularly polarized phosphorescent performance with targeted spectral position. The inverse customization of materials with user-specified circularly polarized fluorescent/phosphorescent performance can be achieved, favoring their application in multicolor display and multidimensional information encryption.

Cili fruit is rich in nutrients, but its sourness is difficult to accept. Kombucha is a fermentation-derived functional beverage with widespread consumer acceptance due to its balanced flavor profile. In this study, the fermentation of Cili juice with SCOBY to improve its flavor, the effect of fermentation conditions on the quality of Cili kombucha beverages was explored. Results showed that the TSS of Cili kombucha beverages decreases during fermentation, while the total and organic acids increase. The fermentation conditions of Cili soft beverage (CSB) and Cili alcoholic beverage (CAB) optimized by orthogonal experiment are as follows: the Cili juice, sucrose, kombucha fermentation broth, and fermentation temperature were 15%, 16%, 15%, 24℃ and 5%, 16%, 25%, 28℃. The total flavonoid content, SOD activity, and antioxidant capacity in CSB and CAB all increased during fermentation. The content of Vc and total phenolic in CSB increases during fermentation, while CAB decreases. The correlation analysis shows that the content of Vc and total flavonoids is the main contributing compound for the antioxidant capacity in CSB and CAB. In conclusion, fermented Cili juice with kombucha not only improves the taste of Cili juice but also increases the bioactive compounds and antioxidant capacity of kombucha beverages.

Lactylation, a lactate-mediated post-translational modification, has garnered significant attention for its pivotal role in epigenetic modulation. However, the intricate interplay between lactylation and ferroptosis in lung adenocarcinoma (LUAD) remains to be fully elucidated. Utilizing metabolomic profiling and comprehensive metabolic library screening, our study uncovers that ferroptosis markedly enhances lactic acid accumulation and subsequent protein lactylation, which in turn confers resistance to ferroptosis in LUAD cells. Functional assays, comprising cell viability tests, lipid peroxidation detection, as well as malondialdehyde and glutathione measurements, collectively reveal that SUMO2-K11 lactylation (SUMO2-K11la), the most prominently elevated lactylation in response to ferroptosis induction, serves as a pivotal factor in determining ferroptosis resistance. Sumoylation proteomics and co-immunoprecipitation assays reveal that SUMO2-K11la impairs the interaction between SUMO2 and ACSL4. Consequently, this disruption facilitates the degradation of ACSL4, thereby disrupting lipid metabolism and effectively mitigating ferroptosis. Furthermore, AARS1 is identified as the lactyltransferase and HDAC1 as the delactylase for SUMO2-K11la. Based on these findings, we develop a cell-penetrating peptide that competitively and specifically inhibits SUMO2-K11la. This peptide significantly potentiates ferroptosis and sensitizes LUAD to cisplatin in xenograft models, while enhancing chemoimmunotherapy responses in spontaneous lung cancer models. Overall, our findings imply that SUMO2-K11la is a pivotal regulator of ferroptosis resistance in LUAD, and suggest a promising strategy to potentiate ferroptosis-based cancer therapies via targeting SUMO2-K11la by the cell-penetrating peptide.

High-fructose corn syrup (HFCS) is an agro-source product and has been the most commonly used substitute for sugar as sweetener in food industry due to its low price and high solution property. In this study, the F55 HFCS, rich in fructose and glucose, was first tested for biomass and docosahexaenoic acid productions as a mixed carbon source by a newly isolated Aurantiochytrium sp.YLH70. After the compositions of the HFCS media were optimized, the results showed that the HFCS with additions of metal ion and vitamin at low concentrations was suitable for biomass and docosahexaenoic acid productions and the metal ion and sea salt had the most significant effects on biomass production. During the 5-l fed-batch fermentation, total HFCS containing 180 g l −1 reducing sugar was consumed and yields of biomass, lipid, and DHA could reach 78.5, 51, and 20.1 g l −1 , respectively, at 114 h. Meanwhile, the daily productivity and the reducing sugar conversion yield for docosahexaenoic acid were up to 4.23 g l −1 day −1 and 0.11 g g −1 . The fatty acid profile of Aurantiochytrium sp.YLH70 showed that 46.4 % of total fatty acid was docosahexaenoic acid, suggesting that Aurantiochytrium sp.YLH70 was a promising DHA producer.

Purpose The present study is aimed at designing an appropriate co-delivery system for chemotherapeutic drugs and gene drugs with high loading capacity, on-demand release behaviors, efficient endosomal escape, and enhanced nucleic localization, thereby providing efficacious antitumor activity. Methods Schiff-base linked imidazole dendritic mesoporous silica nanoparticles (SL-IDMSN) were developed and employed to load doxorubicin (DOX) and survivin shRNA-expressing plasmid (iSur-pDNA) to form nanocomplexes. The nanoparticles were assessed by structural characterization, drug loading and release, cellular uptake, intracellular distribution, gene transfection, in vitro anti-proliferation of hepatoma cells, and in vivo tumor growth inhibition in H-22 tumor bearing mice. Results SL-IDMSN showed high loading capacity for both DOX and iSur-pDNA due to their hierarchical mesostructures. The cleavage of Schiff-base linkage on SL-IDMSN in the weakly acidic endosomes/lysosomes led to microenvironment-specific release of both DOX and iSur-pDNA. Meanwhile, the imidazole modification could trigger the efficient endosomal escape via proton sponge effect, thereby enhancing nuclear accumulation of iSur-pDNA and gene silencing efficiency. More importantly, these superior performances of SL-IDMSN resulted in their improved inhibitory effects on in vitro cancer cell proliferation and in vivo tumor growth. Conclusions SL-IDMSN is a microenvironment-sensitive and biocompatible nanocarrier for the co-delivery of DOX and iSur-pDNA, which might be a promising carrier for co-delivery of chemotherapeutic drugs and gene drugs for synergistic cancer therapy.

A highly binding dummy template surface of molecularly imprinted polymers (MWNTs-MIPs) was synthesized on multi-walled carbon nanotubes surface using 2-phenylpropionic acid as dummy template, 4-vinylpyridine as the functional monomer, ethylene glycol dimethacrylate as the cross-linker, and DMF as porogen by precipitation polymerization method. MIPs were characterized by FT-IR spectroscopy, scanning electron microscope, thermo-gravimetric analysis, and nitrogen adsorption-desorption experiment. Adsorption and selectivity experiments of MIPs and non-imprinted polymers (NIPs) verified that the MIPs had a good selectivity and adsorption properties for five 2-phenylpropionic acid nonsteroidal anti-inflammatory drugs (NSAIDs). Imprinted polymer was used as a sorbent material for μSPE in current work and μSPE-DLLME method was selected for pretreatment of water samples. The μSPE-DLLME method was successfully used for the pre-concentration of five non-steroidal anti-inflammatory drugs in different environmental water samples prior to ultra-high performance liquid chromatography-tandem mass spectrometry. Efficiencies of μSPE and DLLME were thoroughly investigated and optimized in this study. The optimal results were obtained by using 3 mL of 1% formic acid-acetonitrile as elution solvent and dichloroethane and acetonitrile as extractant and disperser solvent, respectively. Limits of detection and quantification of five NSAIDs for different water matrices varied from 0.50 to 1.10 ng L −1 and 0.93 to 2.20 ng L −1 , respectively. Each target analyte had a good linearity in its corresponding concentration range. Enrichment factors of target analytes ranged from 91 to 215. Recoveries of the target analytes were between 72.43 and 113.99% at the concentration levels of 0.02, 0.1, and 0.5 μg L −1 . The developed method was successfully applied to extraction and analysis of NSAIDs in different water samples with satisfactory results which could help us better understand their environmental fate and risk to ecological health.

There are some drawbacks such as the propagation and spread of bacteria and viruses during the use of normal paper. Therefore, this work designed a starch styrene-acrylic antibacterial emulsion for improving the paper properties. The modified antimicrobial monomer was prepared by the subject-object recognition of β-cyclodextrin with hydrophobic modified titanium dioxide. The antibacterial performance of prepared emulsion was tested by Escherichia coli, Staphylococcus aureus. And the mechanical properties of the modified paper were measured according to the national standards. The results showed that the antibacterial emulsion has excellent comprehensive performance with the viscosity of 1750 mPa·s, the inhibition ring diameter of 11.82 mm, the good chemical stability and storage stability. Therefore, the proposed cationic starch styrene-acrylic antibacterial emulsion has promising applications in paper surface modification.

During the tantalum ore smelting process, radioactive substances such as uranium and thorium accumulate in the slag, posing significant environmental risks if not properly treated. The traditional acid leaching method remains suboptimal for extracting these elements from tantalum slag. To address this limitation, this study employed aluminum salt as leaching aid, effectively enhancing uranium and thorium extraction efficiency. This approach offers a novel methodology for recovering uranium and thorium from refractory slag generated after tantalum ore smelting.
