Because of the prevailing issue of water scarcity , the application of non-aqueous media Decamethylcyclopentasiloxane (D5) was employed in the chemical fiber dyeing and washing process. Confocal laser scanning microscope (CLSM) and X-ray photoelectron spectroscopy (XPS) analysis have been carried out to analyze the penetration of D5 into the interior of nylon fiber and its distribution in fiber cross-section. The solubility of pure disperse dye in D5 has been measured to check the feasibility of dispersing agent exclusion from dyeing formulation. For developing the solvent dyeing and washing process for nylon, nylon fabric was dyed with pure disperse dyes in D5 solvent and washed with D5 without any process auxiliaries. Findings from CLSM and XPS spectrum showed that D5 can diffuse into the nylon fabric surface with and without the addition of accelerant. And accelerant doesn’t affect D5’s ability to penetrate and uniform distribution within the fiber structure. As compared to aqueous dyeing, the 30 and 43 percent increase in K/S was achieved for azo and anthraquinone dyes by using D5 as dyeing media. Furthermore, more than 99 percent solvent can be recycled or recovered. The level dyeing with commercial dyes under conventional dyeing conditions in D5 solvent dyeing media prove the commercial feasibility of this dyeing technology .

Rubidium (Rb) is a valuable rare alkali metal that plays a crucial role in various high-tech applications, but extracting Rb from conventional sources poses sustainability challenges. A considerable amount of Rb is found in potassium chloride (KCl) salts, which can serve as a sustainable source depending on the extraction methods. Current liquid-phase methods are problematic due to the low Rb/K separation factor and high consumption of energy, water and chemicals. Extracting Rb directly from solid KCl salts is a promising approach, but achieving efficient recovery remains a challenge. Here we propose a crystal ripening microextraction strategy that enables in situ extraction of Rb from solid KCl salts with high selectivity, simplicity and high efficiency. By applying this strategy, we recovered 92.37% of Rb from KCl salts with an initial Rb content of 113 ppm. Compared with liquid-phase extraction, our approach results in a 97.57% reduction in energy consumption, a 22.24% increase in recovery efficiency and a 13.46-fold higher Rb/K separation factor, which substantially enhance environmental and economic benefits. In addition, this approach is suitable for recovering other target metals needed for various industrial applications directly from different solid metallic salts, providing a pathway to improve the sustainability of critical metal supply.

Flexible pressure sensors play a vital role in advancing wearable electronics by enabling precise health monitoring, human-machine interfaces, and environmental sensing. MXene-based piezoresistive sensors have garnered significant attention due to their exceptional electromechanical properties. However, enhancing their performance and ensuring environmental sustainability simultaneously still remain critical challenge. In this study, we prepared hydroxyl-rich deacetylated cellulose acetate (DCA) fibers and attached MXene to the surface to form a three-dimensionally interconnected conductive network. Taking advantage of the typical micromorphology and in turn the high electrical conductivity modulation, the resulting MXene/DCA (MDCA) flexible sensors exhibited exceptionally high sensitivity (54.62 kPa–1), excellent linearity in the range of 0–40 kPa (R2 = 0.998), fast response/recovery time (154/125 ms), and outstanding long-term durability over 10 000 compression cycles at 12.37 kPa without significant degradation. This study offers promising insights into the development of high-performance, environmentally friendly piezoresistive sensors.

Seed coating technology is vital in agriculture, enhancing seed protection and growth. However, conventional coatings often include chemical fungicides that pose environmental risks, highlighting the need for sustainable alternatives. This study explores silk fibroin (SF), a natural biopolymer with excellent film-forming properties, as a potential seed coating agent, addressing its antimicrobial limitations by combining it with the commercial agent CRUISER®and the antimicrobial peptide Nisin. Experimental methods included solution stability analysis, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscope (SEM), and growth assessments of wheat seeds. Findings reveal that silk fibroin-CRUISER®(SC) composites form stable β-sheet structures, enhancing the coating’s mechanical strength. SF-based coatings improved seedling emergence rates (up to 1.65-fold), plant height (up to 1.05-fold), and root growth (up to 1.2-fold), especially under cold stress. The addition of Nisin further significantly boosted the antibacterial properties, providing sustained pathogen inhibition (p< 0.01). Identifying the optimal concentration of SF was essential for achieving a balance between protection and breathability, a key factor for industrial application. This research provides valuable insights into the development of eco-friendly seed coatings, presenting a viable and sustainable alternative to traditional chemical-based options in agricultural practices.

Adsorption is considered to be a promising butanol recovery method for solving the issue of inhibition in the ABE (acetone-butanol-ethanol) fermentation. As a byproduct in the second generation biobutanol industry, lignin was found to be a good adsorbent for the butanol enrichment. It is conducive to the full utilization of renewable lignocellulose biomass resource. Kinetic and equilibrium experiments indicated that lignin had a satisfactory adsorption rate and capacity that are comparable to those of many synthetic materials. Multicomponent adsorption experiments revealed that lignin had higher adsorption selectivity toward butanol than that of ethanol and acetone. The adsorption capacity of lignin for butanol first increased and then gradually decreased with increasing temperature. And maximum adsorption capacity reached 304.66 mg g −1 at 313 K. The inflection point of temperature is close to the ABE fermentation temperature of 310 K. The condensed butanol by desorption was 145 g L −1 , with a satisfying regeneration performance. 1 H NMR and FT-IR spectra indicated that the aromatic units of lignin formed π -systems with A/B/E. The π -system is particularly significant for butanol due to its longer hydrocarbon chain. These results could contribute to the emerging lignin-based materials for butanol separation.

Sustainable underwater adhesives have drawn much interest in promising applications and environmental engineering. However, developing a convenient strategy to combine recyclability and underwater adhesion into adhesive materials remains a formidable challenge. In this work, a degradable and closed-loop recyclable underwater adhesive tackifier is designed by nucleotide, via the ring-opening polymerization of thioctic acid in the presence of 5′-adenosine monophosphate and methacrylatoethyl trimethyl ammonium chloride. The nucleotide-tackified adhesives present an excellent underwater adhesion for various materials, tissues, and on-demand detachment adhesion behavior. The underwater adhesives demonstrate reusability, degradability, and closed-loop recyclability of dual monomers of thioctic acid and 5′-adenosine monophosphate. Interestingly, the waste residues of the underwater adhesives demonstrate processability and can be employed again in the construction of tough adhesive interfaces in both air and underwater, with further expanding sustainability. It is envisioned that the strategy of nucleotide-tackified sustainable underwater adhesives would offer promising insights for advancing sustainable and recyclable adhesive materials.

In this study, an efficient and eco-friendly method was developed for continuous liquid–liquid extraction of lutein from microalgaeChlorella vulgaris. By employing a limonene-based biphasic liquid system, high-purity lutein was successfully obtained from the crude extract in a single run via centrifugal partition chromatography (CPC). Evaluation and optimization results demonstrated that limonene could effectively serve as a replacement forn-hexane as the solvent system for lutein extraction, exhibiting natural renewability and minimal environmental impact. Furthermore, the elution–extrusion operation mode was employed to fully exploit the liquid nature of the stationary phase in the extraction process, allowing for continuous sampling and separation without interruption. This proposed protocol offers a sustainable and environmentally friendly alternative for extracting valuable ingredients from microalgae biomass, demonstrating its potential as a scalable solution for producing lutein-enriched ingredients applicable to functional foods and nutraceuticals.

Nanocellulose extracted from agricultural waste for the development of reinforced sustainable composites is needed, due to a greater environmental responsibility and awareness of environmental pollution. In this work, the extraction of nanocellulose (GNC) from ginger residue was conducted via acid hydrolysis without complicated pretreatments. The potential application of GNC as a reinforcing agent for sustainable composite films was also explored. The results showed that the obtained GNC exhibited a rod-like shape with a high aspect ratio (15.75 ± 4.25). X-ray diffraction patterns revealed a cellulose II structure with a crystallinity index of 88.47 %. The reinforcing effects of GNC were evaluated in composite films made from different matrices, including sodium alginate (SA) and chitosan (CS), to assess its performance in enhancing material properties. The incorporation of 5 % of GNC significantly improved the tensile strength of SA and CS by 94 % and 64 %, respectively. Notably, the addition of GNC also enhanced the elongation at break of the SA-based films. This study demonstrates that ginger residue is a promising and sustainable feedstock for extracting nanocellulose, which can serve as an effective reinforcing agent in biocomposite films.

The epoxy resin made from petroleum-based bisphenol A has clear shortcomings both in raw material sustainability and the heat resistance as well as mechanical properties of polymers, which limits its use in high-performance products. A multifunctional epoxy resin was derived from sustainable resveratrol and phloroglucinol via a solvent-free procedure. The matrix showed its advantages in phase transition temperature ( T g , 247.5°C), storage modulus (4.14GPa), flexural strength (184.70 MPa), tensile modulus (6.14 GPa), and lap shear strength (28.15 MPa). Besides, the thermal conductivity (0.151 W/m•K), and coefficient of thermal expansion (84 ppm/°C) suggested its outstanding structural stability and dimensional stability below 250 °C. Moreover, it also possessed an intrinsic flame retardancy. The highly extended performances implied its promising applications in lightweight, fireproof, and heat insulation engineering.

Wood has garnered renewed interest due to its capacity to reduce carbon emissions when replacing non-renewable materials. Wood modification is often necessary because achieving optimal performance solely from the wood itself is challenging. Strategies for wood modification fall short of being genuinely sustainable and eco-friendly. In this context, a catalyst-free esterification method mediated by maleic anhydride (MA) is introduced for modifying wood. Notably, this approach aligns with principles of recycling, reuse, and reduction. A comprehensive comparison of MA-mediated wood esterification versus TEMPO-mediated wood oxidization highlights the effectiveness and superiorities of the MA esterification approach. Delignified wood esterified by MA (MA-DW) exhibits higher charge content (2.42 ± 0.24 vs. 0.53 ± 0.08 mmol/g), superior mass gain (18.4 ± 2.6 wt% vs. −15.92 ± 3.5 wt%), efficient recycling capability of the reaction medium (MA could be recycled five times, while TEMPO cannot be recycled), and integrity of the final products (retaining intact geometry vs. complete disintegration) compared to TEMPO-oxidized delignified wood (TEMPO-DW). Moreover, the MA-DW platform can serve in energy storage applications as an electrode or in sewage remediation applications as a catalyst. The esterification method mediated by MA provides an eco-friendly pathway for modifying wood, serving as a platform for creating diverse materials, potentially offering innovative concepts and insights for wood modification research.

Sustainable nitrogen fixation is essential for advancing agriculture and chemical production. However, existing methods face trade-offs between energy intensity and efficiency. Low-activation-energy approaches fail to dissociate nitrogen effectively due to the strong N2 bond, while energy-intensive methods face energy loss from product decomposition. Here, we present an in-water plasma-based nitrogen fixation system that integrates metal electrodes (W, Al, and Fe) to achieve in situ activation of pulsed discharging plasma. This design enables efficient nitrogen dissociation and selective product formation of soluble nitrogen species (nitrate, nitrite, and ammonia), while minimizing decomposition through optimized product diffusion. This system achieves an energy consumption of 1.14 MJ mol–1 and a production rate of 12.9 mmol h–1 cm–2 for total soluble nitrogen species, surpassing other water-assisted methods and rivaling the Haber–Bosch process. Operating under ambient conditions, this electricity-driven, carbon-neutral approach offers a sustainable and efficient solution for decentralized application in agriculture and chemical production.

For the purpose of degrading tetracycline (TC), a three-dimensional electro-oxidation (3D EO) system using particle electrodes of carbon black (CB) and polytetrafluoroethylene (PTFE) was developed. The CB-PTFE particles fabricated at a CB/PTFE mass ratio of 3:2 and calcination time of 60 min exhibited the high performance for TC removal, as well as low energy consumption and high mechanical strength. TC removal efficiency reached 95% within 15 minutes, driven by a pseudo-first-order reaction with a rate constant of 0.20 min −1 . The process incurred an energy consumption of 20.31 kWh/m 3 . The surface characterizations indicated that the CB-PTFE particles possessed excellent catalytic properties for H 2 O 2 production. Despite the substantial influence of voltage and particle dosage on performance, the system demonstrated consistently high efficiency in TC removal regardless of solution pH within the range of 3–11. Quenching experiments and probe experiments using benzoate suggested that the surface-bound hydroxyl radicals (•OH (ads) ) dominated (64.7%) the oxidation of TC in the 3D CB-PTFE EO system. The •OH (ads) was produced by the reduction of H 2 O 2 on the particle surface. Products examination by LC-MS-MS confirmed a degradation pathway of TC by •OH attacking. These findings indicate that the CB-PTFE EO system has unique advantages and potentials in treating antibiotics due to its high oxidizing capacity, a wide range of applicable pH, no chemical adding, and self-cleaning.
