Mikania, a well-accepted invasive plant in nature, has been difficult to be completely removed even based on chemical herbicides. Moreover, the employment of chemical herbicides will lead to hazardous results to health or environment. In this study, the whole-new carbon polymer quantum dots (CPDs) have been afforded in the light of Mikania as the carbon source. Moreover, sesame has been selected as a plant model and the effect of such kind of nanoscale fertilizer on its growth has been explored. Results support that CPDs at a concentration of 0–0.4 mg/mL possess a physiological response to the germination and no toxicity has been observed. Confocal images demonstrate that CPDs can spread through the roots of sesame seeds to the stems and leaves. The utilization of micrantha-derived carbon quantum dots with fluorescence characteristics in the growth of sesame will give rise to new ideas for waste-plant management and biological control, and strengthen the importance of nanomaterials in related fields.

Spermidine is a naturally occurring polyamine with multiple biological activities and potential food and agricultural applications. However, sustainable and scalable spermidine production has not yet been attained. In this study, a homospermidine synthase (HSS) from Pseudomonas frederiksbergensis (PfHSS) capable of catalyzing the synthesis of spermidine from 1,3-diaminopropane and putrescine was identified based on multiple sequence alignment using Blastochloris viridis HSS (BvHSS) as a template. The optimal reaction pH and temperature for purified PfHSS were determined to be 8.5 and 45 °C, respectively, and K+ was able to promote the enzyme activity. Further analysis of the structural and functional relationships through molecular docking and molecular dynamics simulation indicates that glutamic acid at position 359 is the essential residue for the enzyme-catalyzed synthesis of spermidine. The whole-cell catalytic reaction yielded 1321.4 mg/L spermidine and 678.2 mg/L of homospermidine. This study presents a novel, promising, and sustainable biological method for producing spermidine.

The development of sustainable and recyclable adhesives simultaneously requiring high strength and ductility is challengeable. Herein, we synthesized furan ring-containing copolyesters as sustainable, strong, and tough adhesives. FTIR and 1H NMR analyses confirmed the successful synthesis of copolyesters. Furthermore, structures and physiochemical properties of copolyesters were easily tunable by varying the feeding ratio of comonomers. The obtained copolyesters exhibited several interesting features as adhesives, which synergistically resulted in superior adhesion behavior, including high adhesion strength (12.60 MPa), satisfactory toughness (work of debonding = 2623 N m–1), wide temperature adaptability (adhesion strength = 8.23 MPa at −70 °C and 3.83 MPa at 100 °C), and excellent solvent resistance (9.27 MPa of adhesion strength in N,N-dimethylformamide after 24 h). The present work significantly advances and provides perspectives on the design of strong and tough sustainable adhesives.

The complete separation of vanadium (V) and chromium (Cr) from chrome vanadium slag is still challenging. Many studies focus on the activity of vanadium, while the effect of the other element chromium and their mutual interaction are ignored. Here, we found that proper concentration of chromium can promote the extraction efficiency of vanadium. The extraction of V and Cr with various mass ratios ranging from 8:1–4:3 at different initial pH values using primary amine N1923 were studied. The extraction efficiency of V reached nearly 100%, while none of Cr was extracted when the mass ratio of Cr and V is 0.5 under proper pH. Through the dynamic monitoring of species evolutions during extraction, the transformation of the two metals and advantage extracted species were analyzed. Cr would transfer H + for the combination of V 3 O 9 3- /V 4 O 12 4- , providing a great contribution to the continuous extraction of V. The real leachate was applied and 99.9% vanadium pentoxide was produced at a scale of 50 L/h. This paper offers deep insights of the separation of similar metal elements, and guide sustainable vanadium recovery from hazardous waste .

Producing room temperature phosphorescent materials from natural sources is essential for sustainability. However, either toxic chemical reagents or complicated processing is still required to produce such phosphorescent materials derived from natural resources. Here, we produce sustainable room temperature phosphorescence (RTP) materials from wood and sugar. Specifically, sugar is introduced into a wood matrix, which confines the lignin in the wood matrix in situ . As a result, the treated wood (sucrose wood [S-wood]) exhibited RTP emissions with a lifetime of ∼284.4 ms. Life cycle carbon analysis indicates that ∼8.1–11.2 kg CO 2 is produced during the preparation of S-wood, which is lower than for other similar materials. Moreover, the S-wood could be naturally degraded in the soil over 40 days. As a demonstration of the practical potential, S-wood is used for visual decorations and anti-counterfeiting applications.

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.

In this work, the approach for separating paraffin wax is proposed by using Span 80 combined with switchable water N,N,N′,N′-tetramethyl-1,6-hexanediamine (TMHDA), where the emulsification of paraffin wax can be promoted and paraffin wax is also separated sustainably. Here, the Span 80-containing mixture system exhibits an enhanced emulsification ability and CO2-switchable behavior upon the addition of TMHDA. Then, the paraffin wax is effectively emulsified by this switchable system containing Span 80 and TMHDA. Based on the detection of water separation rate, rheological behavior, and micrographs of emulsified paraffin wax, it is found that the emulsification of paraffin wax can be improved by increasing the paraffin wax content and Span 80 content, and the viscosity of the paraffin wax is reduced after emulsification by this switchable system, which ascribes to the dispersion of wax crystals. In addition, the paraffin wax is separated upon introducing CO2, and the TMHDA solution is recovered upon treating with N2 at 65 °C after separating the paraffin wax. The sustainable separation of paraffin wax results from the aggregation of wax crystals because of the reduced obstruction of oil droplets for wax crystals caused by the high ionic strength and the reduced surface activity of this system upon introducing CO2. Herein, it is expected that this sustainable separation can be applied in deposited wax removal in pipelines of crude oil transport.

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.

Fish scales, considered as low-value by-products, contain peptides and hydroxyapatite that can be applied to produce peptide chelated calcium directly. This study developed a sustainable and one-pot fabrication method for the peptide-chelated calcium from fish scale hydrolysates (FSP-Ca). During pepsin hydrolysis, the releases of peptides (FSP), calcium, and phosphate from fish scales occurred simultaneously, and the chelation was also effectively performed. After a 6-h hydrolysis, the yield of FSP was 46.18%, and the dissolution rate of calcium was 49.53%. Under the optimal conditions (pH 7, chelation time of 25 min, and chelation temperature of 48 °C), a high chelation rate of 86.16% was obtained, with a calcium content of 81.8 mg/g. The results of UV absorption, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD) and scanning electron microscopy (SEM) confirmed the successful chelation between FSP and calcium derived from fish scales. The –NH 2 , –COO – , N–H, C=O, C–H, and –OH groups in FSP participated in the formation of FSP-Ca. Graphical Abstract

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.
