Building lithium fluoride (LiF)-rich solid electrolyte interphases (SEIs) by the decomposition of fluorinated salts has been widely adopted to be effective to suppress lithium dendrite growth, thus prolonging the lifespan of fast-charging lithium metal batteries (LMBs). Nevertheless, the slow dissociation of LiF salts reduces both their utilization and the formation of inorganic SEI. Herein, cellulose acetate (CA) was incorporated into the electrolyte to create an inorganic-rich SEI through ester groups, where the lithiophilic oxygen atoms in the ester group (C═O) enhanced lithium-ion diffusion and anion dissociation rates. Therefore, rapid ion diffusion and dendrite-free anodes were achieved in the ester-based electrolyte with CA (named as CA-E). As a result, the lithium symmetric batteries with the CA-E electrolyte exhibited stable cycling performance for 5,000 h at a current density/capacity of 3 mA cm−2/1 mAh cm−2, while a short-circuiting was observed after ~450 h for the bare electrolyte. Benefiting from the rational design, lithium iron phosphate batteries with the CA-E electrolyte showed an excellent C-rate performance with a capacity of 100.7 mAh g−1 at the rate of 10 C. Moreover, a specific capacity of 110.3 mAh g−1 was maintained after 300 cycles at the rate of 6 C with a Coulombic efficiency of 99.87%. This work proposes a new approach to dendrite inhibitors for fast-charging LMBs.

In order to solve the drawbacks of carboxylated cellulose nanocrystals (CNCs) prepared by critic acid (CA) hydrolysis method, such as low yield and low esterification degree, herein, ball milling assisted CA hydrolysis method was applied to obtain carboxylated CNCs and cellulose nanofibers (CNFs) with fine and uniform size, high yield and carboxyl content, good crystallinity, and good thermal stability. It was discovered that the diameter of CNCs and CNFs were decreased and the size uniformity was improved. The yield of CNCs was obviously improved to 39.8 % due to the promoted esterification reaction, which was 3.3 times of that without ball milling. Moreover, the carboxyl group content of CNCs and CNFs were improved to a maximum of 0.52 and 0.48 mmol/g, respectively. As ball milling progressing, more amorphous regions were destroyed and cellulose bundles were dissociated, resulting in CNCs and CNFs with high crystallinity. The thermal decomposition temperature of CNCs and CNFs were ranged from 317 to 331℃, which was higher than that had reported. This work provided an effective route for carboxylated CNCs with good yield, esterification degree and other performance, which was beneficial for the subsequent applications in the field of biomaterials.

Capturing CO 2 using clamshell/eggshell-derived CaO adsorbent can not only reduce carbon emissions but also alleviate the impact of trash on the environment. However, organic acid was usually used, high-temperature calcination was often performed, and CO 2 was inevitably released during preparing CaO adsorbents from shell wastes. In this work, CaO-based CO 2 adsorbent was greenly prepared by calcium-induced hydrogenation of clamshell and eggshell wastes in one pot at room/moderate temperature. CO 2 adsorption experiments were performed in a thermogravimetric analyzer (TGA). The adsorption performance of the adsorbents obtained from the mechanochemical reaction (BM-C/E-CaO) was superior to that of the adsorbents obtained from the thermochemical reaction (Cal-C/E-CaO). The CO 2 adsorption capacity of BM-C-CaO at 650 °C is up to 36.82 wt%, but the adsorption decay rate of the sample after 20 carbonation/calcination cycles is only 30.17%. This study offers an alternative energy-saving method for greenly preparing CaO-based adsorbent from shell wastes.

Trypsin is a kind of digestive enzyme capable of catalyzing the hydrolysis of proteins. Abnormal changes in the levels of trypsin can cause a series of pancreatic-related diseases. Therefore, based on the special interface interaction between green-emitting ionic liquid-based carbon dots (G-CDs) and BSA, a highly sensitive fluorescence "on-off" mechanism was developed for detecting trypsin in urine. The G-CDs were synthesized by a one-step hydrothermal approach using 2,5-dihydroxybenzoic acid (2,5-DHBA) and 1-octyl-3-methylimidazolium tetrafluoroborate ([OMIM]PF 4 ). The interaction between G-CDs and bovine serum albumin (BSA) led to the formation of the G-CDs-BSA fluorescence sensing system, which induced aggregation and fluorescence enhancement of G-CDs. The G-CDs-BSA system was disrupted under optimal incubation conditions after the addition of trypsin, and the fluorescence was quenched. According to the fluorescence quenching value (∆F) of the system, the quantitative analysis of trypsin in urine was realized and demonstrated good recoveries. This study not only developed a novel fluorescence sensing system with excellent performance for trypsin detection, but also provided a theoretical basis for the binding of carbon dot-protein systems.

Auxenochlorella pyrenoidosa 's industrial utility is closely associated with the concentration of high-value products. This study focuses on the effects of cinnamic acid (CA) and its derivatives, which known as secondary metabolites in higher plants and effective plant growth regulators, on the growth and metabolic profiles of A. pyrenoidosa . It was discovered that CA and its derivatives significantly enhance the biomass of A. pyrenoidosa under conditions of 10 mg/L over 48 h or 100 mg/L over 120 h. Cells treated with 10 mg/L CA exhibited lower oxidative stress and maintained robust metabolic activity. Metabolic pathways, including those for carbohydrates, lipids, small peptides, and cofactors, were stimulated, leading to the accumulation of a wide array of bio-products, notably high-value products such as α-linolenic acid, cis-4,7,10,13,16,19-docosahexaenoic acid (DHA), nicotinamide adenine dinucleotide plus hydrogen (NADH), glutathione, and vitamins B2/B3. This study demonstrates that CA and its derivatives are good nutritional enhancers for cultivating A. pyrenoidosa , highlighting their potential for broad application in biotechnological industries.

The inefficient application and ineffective delivery of nematicides on agriculture have caused serious waste of pesticides and environmental pollution. It is urgent to develop new carriers for nematicides that are long-acting and environmentally friendly. In this study, biodegradable cellulose acetate was used as the carrier material to prepare two kinds of fluopyram (Flp)-loaded nanofibers by coaxial electrospinning (CA-CE@Flp) and uniaxial electrospinning (CA-UE@Flp), respectively. During the preparation of two Flp-loaded nanofibers, we deposited them on the root of the plant. In the 45-day pot experiment, the root-protective films would release Flp to protect root from the Meloidogyne incognita infection. The control effects of CA-UE@Flp and CA-CE@Flp are 80% and 64%. In the distribution of Flp around the rhizosphere soil, the CA-CE@Flp with sustainable release property performed the more uniform distribution of Flp, which led to the long-term control effect against M. incognita and plant safety. CA-UE@Flp with high release efficiency can achieve short-term disease prevention and control. The novel Flp-loaded nanofiber precision application developed provides a new strategy for the green, safe, and efficient application of nematicides and shows a great potential for electrospinning fiber products on plant protection.

Heavy metal wastewater pollution has been a globally important and serious issue for the industrial manufacturing center. Herein, we developed a novel CAP@Ui0-66-NH 2 @PPy nanocomposite fibrous membrane, by combining the in-situ growth and oxidative polymerization technical routes, which possessed a high specific surface area and abundant amino-active sites to remove Cr (Ⅵ). Systematic characterization showed that the porous structure and in situ growth of MOF provided sites for polymerization of charged polypyrrole (PPy), resulting in the large specific surface area (78.837 m 2 /g) of CAP2@Ui0-66-NH 2 @10 %PPy. The maximum adsorption capacity was as high as 312.70 mg/g at 298 K, which was significantly better than that of CAP (CA and PVP electrostatic spinning and then washing off the PVP) nanomembranes. The adsorption process was consistent with the proposed secondary kinetic and Langmuir model, and the high adsorption capacity was maintained after five rounds of cyclic adsorptions. Through XPS analysis, the abundant amino groups on the surface of the adsorbent material were protonated, caused the electrostatic attraction and ion-exchange interaction with the anion Cr(Ⅵ). These protonated amino groups were able to reduce the toxic Cr (Ⅵ) to non-toxic Cr (Ⅲ), which was immobilized on the surface of the material through chelation. The MOF lattice achieved in-situ growth on porous CA nanofibrous membranes, which significantly enhances the mass-transfer dynamics and the membrane cycling stability, the amine-based functionalization of the UI0-66-NH 2 improved the coordination activity and increased the adsorption efficiency, and polypyrrole (PPy) conductive layer promoted the directional migration of Cr (VI) and effectively suppressed the interference of competing ions. In sum, the prepared CAP@Ui0-66-NH 2 @PPy hybrid fibrous membranes showing great potentially applicable for heavy-metal wastewater treatment.

The development of environmentally friendly biodegradable films is urgently required for reducing the plastic pollution crisis and ensuring food safety. Thus, here we aimed to prepare ZIF-8 that has delivery ability for gallic acid (GA) and further incorporated this material (GA@ZIF-8) into carrageenan (CA) matrix to obtain a series of CA-GA@ZIF-8 films. This design significantly improved the mechanical strength and UV barrier and reduced water vapor permeability, moisture content , and swelling rate of the CA films. CA-GA@ZIF-8 films exhibited sustainable release of GA and controlled migration of Zn 2+ up to 144 h in a high-fat food simulator. Also, the composite films performed high-efficiency antioxidant activities (83.29 % for DPPH and 62.11 % for ABTS radical scavenging activity) and 99.51 % antimicrobial effects against Escherichia coli O157:H7 after 24 h. The great biocompatibility of GA@ZIF-8 and CA-GA@ZIF-8-10 % was confirmed by hemolysis, cell cytotoxicity, and mice model. Finally, the preservation experiments showed that CA-GA@ZIF-8 films could effectively maintain freshness and reduce the growth of microorganisms and oxidation of lipids during the preservation of beef. These results suggest that CA-GA@ZIF-8 films hold promising potential for improving the quality preservation of beef.

A new type of bifunctional Deep Eutectic Solvent (DES), crafted from a blend of ethylene glycol (EG), ethanol (EtOH) and citric acid (CA), has been developed for the efficient and selective extraction of valuable metals from spent lithium-ion batteries (LIBs) cathode materials. This innovative solvent leverages the inclusion of EtOH to fine-tune the solubility of metal complexes, notably enhancing the separation of Co by reducing its concentration in the leachate from 3.099 g/L to 0.7508 g/L. This adjustment facilitates the in situ separation of Li and Co/Ni/Mn. Through meticulous single-factor leaching experiments, the influence of various parameters on the extraction efficiency of Li and Co was explored. It is revealed that EtOH’s presence not only improves separation efficiency but also promotes the precipitation of a novel cobalt citrate complex, Co 3 (C 6 H 6.8 O 7 ) 5 , formed between Co 2+ and CA. A comprehensive analysis of the Co leaching and separation mechanism was conducted, characterizing the properties of the formed complex. Optimal extraction conditions (150 °C, 16 h, 8 g/L, 6 EG: 6 EtOH: 1 CA) resulted in the leaching of 97.4 % of Li from LiCoO 2 and 94.4 % from Li 3.2 Ni 2.3 Co 0.9 Mn 1.4 O 6.3 , along with a partial Mn (52.6 %) and small amounts of Co/Ni (<15 %). The leaching mechanism and reaction kinetics were investigated, confirming that diffusion is the rate-limiting step of the reaction. After 5 cycles of DES leaching, the η Li exceeded 90 %, demonstrating the reusability of DES. Through precipitation, evaporation, and calcination processes, high-purity CoC 2 O 4 ·H 2 O, EG, EtOH, and Li 2 CO 3 can be recovered. This research introduces EtOH as a key component in DES formulation, offering a strategy to enhance the selectivity of dual-functional DESs.

Hemostatic powder, which can absorb large amounts of water and tends to produce repeated hydration with tissue, has been clinically proven as an ideal engineering material for treating wounds and tissues. We herein designed a polypeptide-based hemostatic powder. A water-soluble polypeptide, γ-polyglutamic acid (γ-PGA), was mixed with the polyethyleneimine (PEI), N-hydroxysuccinimide, and 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide. The solution of these polymers was lyophilized to harvest the γ-PGA/PEI powder (PP hemostatic powder). When deposited on a bleeding wound, the PP hemostatic powder can quickly absorb a large amount of blood and interstitial fluid, concentrate coagulation factors, coagulate blood cells, and eventually form a stable mechanical hydrogel. The wound bleeding time of the PP hemostatic powder group was 1.8 ± 0.4 min, significantly lower than that of the commercial chitosan hemostatic powder group (2.8 ± 0.4 min). The PP hemostatic powder was endowed with antioxidant capacity by introducing protocatechuic aldehyde, which can effectively inhibit inflammation and promote wound healing. Therefore, via preparation through a facile lyophilization method, the PP hemostatic powder is expected to find a wide application prospect as a qualified hemostatic powder.Keywords:hemostatic powder;hydrogel;γ-polyglutamic acid;polyethyleneimine;wound hemostasis

The combination of polyphenols and protein can improve the functional characteristics of protein. How to effectively promote the binding of polyphenols to protein is still a difficult topic. In this study, hydrodynamic cavitation (HC) was used to induce the fabrication of complexes between soy protein isolate (SPI) and different polyphenols (tannic acid (TA), chlorogenic acid (CGA), ferulic acid (FA), caffeic acid (CA), and gallic acid (GA)). The effect of HC on the interaction between polyphenols and SPI was investigated, and the structural and functional properties of the formed complexes were characterized. The results showed that HC treatment led to SPI structure stretching, which increased the binding level of polyphenols, especially that of TA (increased from 35.08 ± 0.73% to 66.42 ± 1.35%). The increase in ultraviolet–visible absorption intensity and quenching of fluorescence intensity confirmed that HC enhanced the interaction between polyphenols and protein. HC treatment reduced the contents of free sulfhydryl and amino groups in SPI–polyphenol complexes and altered their Fourier transform infrared spectroscopy, indicating that HC treatment promoted the formation of C–N and C–S bonds between SPI and polyphenols. Circular dichroism spectroscopy indicated that HC treatment altered the secondary structure of SPI–polyphenol complexes, inducing an increase in α-helix and random coil contents and a decrease in β-sheet content. Regarding functional properties, HC treatment improved the emulsification and antioxidant activity of SPI–polyphenol complexes. Therefore, HC is an effective technique for promoting the binding of polyphenols to protein.

Silicon serves as a promising anode material for lithium-ion batteries. However, silicon suffers from low initial coulombic efficiency (ICE) and poor cycling performance due to large volume change, lithium consumption, the formation of a solid-electrolyte interphase (SEI), and low conductivity. To improve the performance of silicon anodes, this work proposed a new strategy for the design of silicon electrode binders based on β -cyclodextrin, citric acid, and sodium alginate, where a binder with a chemical/ionic/hydrogen-bonded triple-crosslinked network was constructed in situ during electrode preparation. The binder with a triple-crosslinked network provided the silicon electrode with a high binding strength, excellent ion/electron permeation network, and robust interfacial protective layer, providing better tolerate volume changes, and inhibiting the interfacial side reactions and the formation of solid-electrolyte interphase, as well as accelerating Li + diffusion during the charge/discharge processes. The prepared silicon electrodes had a higher ICE (92.8%), better cycling stability (1429 mAh/g after 400 cycles at 0.5 C), and superior rate performance (1274 mAh/g at 4 C). This work may guide the design of high-performance binders for silicon electrodes.
