In recent years, pressure sensors with high sensitivity and flexibility have been widely used in the fields of wearable electronics, soft robots, medical monitoring, and so on. In this paper, a through-hole structure comprising of multi-walled carbon nanotubes (MwCNTs)/carboxymethyl cellulose (CMC)/polydimethylsiloxane (PDMS) was constructed through an ice template method and then it functioned as the dielectric layer of a newly made flexible capacitive pressure sensor. The sensitivity, stability, response time, and human applicability of the sensor were fully studied. The experimental method with ice template has the advantages of environmental protection and safety. More importantly, through the regulation of chemical composition, the porous sponge can have a specific pore morphology. The experimental e results showed that the dielectric layer with a through-hole structure had been built successfully and the PDMS resin was impregnated into the through-hole structure. The MwCNTs/CMC/PDMS capacitive pressure sensor possessed a high sensitivity (~ 2.143 kPa −1 ) and good stability in the low-pressure range (0–1 kPa). Moreover, a low detection limit (~ 3 Pa) and fast response time (~ 250 ms) were obtained. Human applicability tests revealed that our flexible sensor could catch the response of the human body swiftly so that it exhibited bright application prospects in wearable electronics.

As society rapidly progresses, environmental issues, including water pollution and ecosystem degradation are steadily worsening. In this work, a novel functional nanofiber composite film based on polyvinyl alcohol (PVA), carboxymethyl cellulose (CMC), and polyethylene oxide (PEO) were prepared by using electrospinning technique. The incorporation of PEO facilitated a more concentrated nanofiber diameter distribution. The prepared composite films were further modified with glutaraldehyde vapor to enhance their hydrophobicity and improve pore-making capabilities on the fiber surface. The nanocomposite fiber film, with its simple preparation process, cost-effectiveness, and environmental friendliness , exhibits a promising prospect in addressing environmental challenges. Notably, the designed nanofiber films demonstrated remarkable efficiency in dye adsorption, owing to the high specific surface area of the fibers and the selective binding of active groups on the fiber surface to the dyes. Moreover, they showed good reusability, which is of great significance for adsorbents. Therefore, the obtained composite films from environmentally friendly preparation process has great application potential in wastewater treatment and dye removal .

Polyacrylamide (PAM) hydrogel is easy to prepare and has been widely used in industrial and biomedical fields. But its mechanical properties and environmental adaptability are very poor. In this work, by introducing carboxymethyl cellulose (CMC) into the PAM crosslink network, a semi-interpenetrating (semi-IPN) network structure was constructed to improve the mechanical properties of PAM hydrogels. PAM/CMC hydrogel microspheres (HMPs) with semi-IPN structure were successfully prepared by in-situ precipitation droplet crosslinking polymerization (PDIC). On this basis, a double locking water strategy was proposed and achieved: firstly, lithium chloride (LiCl) was introduced into PAM/CMC hydrogel to retain the internal water; secondly, the PAM/CMC HMPs were coated with single layer graphene oxide (GO) to restrain the loss of free water on the HMPs surfaces. The morphology, the state of water in HMPs, the compression performance, phase transition behavior and heat transfer performance of the GO coated PAM/CMC/LiCl HMPs (GO@HMPs) were further studied. The experimental results showed that the CMC could effectively improve the compression performance of PAM HMPs, and the PAM/CMC HMPs had also good compression recovery performance. The anti-dehydration performance of PAM/CMC HMPs was effectively improved by the double locking water strategy. The latent heat of GO@HMPs was higher than that of the current commercial phase change microsphere materials. The GO@HMPs had excellent heat absorption ability and were expected to be used in infrared stealth and thermal camouflage fields.

The structural advantages of the membrane material itself are critical to the membrane separation performance. Two-dimensional (2D) graphitic carbon nitride (g-C 3 N 4 ) nanosheets can achieve minimal mass-transfer barrier and high gas sieving performance due to their ultra-thin thickness, inherent surface porosity and abundance of amine groups. However, the 2D g-C 3 N 4 nanosheets are prone to stacking during the self-assembly process, which reduces the membrane permeability. Based on this line, herein, we proposed a concept of construction of 1D-2D intercalated network supported ionic liquid membrane composed by one-dimensional (1D) carboxymethylcellulose ( CMC ) and g-C 3 N 4 nanosheets to overcome the low permeability of 2D graphitic carbon nitride membrane in separating CO 2 /N 2 and CO 2 /CH 4 . The as-prepared 1D-2D intercalated network supported ionic liquid gas separation membrane exhibits superior CO 2 permeance of 953.96 GPU, CO 2 /N 2 selectivity of 55.46 in separation of CO 2 /N 2 , and CO 2 permeance of 854.00 GPU, CO 2 /CH 4 selectivity of 50.62 in separation of CO 2 /CH 4 . In addition, the resulting CMC@g-C 3 N 4 /IL membrane has excellent durability. After 120 h of testing, it still has outstanding separation performance. In short, this concept in this study provides an effective modulation of molecular sieving of g-C 3 N 4 membrane for high-efficiency CO 2 capture by combination of the advantages of the 1D (CMC) and 2D (g-C 3 N 4 ) materials.

It was previously understood that the smelting process involving high-graphite content sulfide concentrates would result in a chemical reaction with oxygen, which would subsequently release a significant amount of CO 2 . This not only contributes to environmental pollution but also hampers smelting efficiency and quality, consequently escalating smelting costs. Therefore, this work improved the purity of sulfide ores by flotation methods using environmentally friendly depressant to depress graphite. The results of the micro-flotation study reveal that the flotation separation of graphite and sphalerite mixed ore was best under the flotation reagent concentration system of 10 mg/L PBX, 10 mg/L CMC and 8 × 10 −5 mol/L CuSO 4 , and the flotation recoveries were 8.22 % and 79.24 %, respectively. Analyses conducted using FTIR and XPS reveals that PBX competed with CMC for the adsorption of Cu 2+ , and exhibited a stronger adsorption for Cu 2+ on the sphalerite surface compared to CMC, which increased the adsorption of PBX with the sphalerite surface. Meanwhile, the graphite is only affected by CMC, which results led to sphalerite surface hydrophobicity and graphite surface hydrophilicity for efficient separation. Further confirmation was provided by DFT and MD simulations that Cu 2+ were adsorbed on the graphite (001) surface through physical interactions. The adsorption order was as follows: CuOH + < Cu 2+ < Cu(OH) 2 . CMC chemisorbed with Cu 2+ on the graphite surface, resulting in an increase in the adsorbed content of CMC on the graphite surface and an improvement in the hydrophilicity of graphite. These results indicate that CMC effectively depress graphite during the flotation separation of graphite and sphalerite.

Traditional pesticide formulations have issues such as poor targeting, low adhesion performance, and a tendency to leach into the environment, causing pollution. In this study, a pesticide delivery platform (PRO@FeMOFs@CMC) with a dual response was designed by encapsulating prochloraz technical (PRO) within Fe-based metal–organic frameworks (FeMOFs) and using carboxymethyl cellulose (CMC) as the gatekeeper. The results showed that PRO@FeMOFs@CMC exhibited a loading capacity of 28.86 % for PRO and efficient adhesion to wheat and rice leaves. This delivery platform showed a significant increase in the release of PRO under environments similar to that produced by a pathogen infection, involving cellulase and glutathione (GSH). Importantly, compared to prochloraz suspension concentrate (PRO@SC), PRO@FeMOFs@CMC exhibited higher fungicidal efficacy against Rhizoctonia cereali and Rhizoctonia solani and its acute toxicity to zebrafish and earthworms was reduced by 3.7 times and 8.6 times, respectively. Compared to PRO@SC, the cells treated with PRO@FeMOFs@CMC had higher cell viability and a significantly reduced apoptosis rate, demonstrating greater safety. Additionally, FeMOFs@CMC showed no evident toxicity to wheat and rice. In summary, PRO@FeMOFs@CMC is an efficient and safe pesticide controlled-release system for the sustainable management of wheat and rice diseases.

Charge transfer and separation play a critical role in the photocatalytic efficiency of photoresponsive materials and their subsequent applications. Herein, for the first time, we constructed a homo-heterostructured S–Cu–FC/CuS modified carboxymethyl cellulose (CMC) hydrogel doped with graphene oxide (GO) (S–Cu–FC/CuS/GO@CMC) through an in situ ionic complexation reaction, which exhibited enhanced photocatalytic performance under 808 nm near-infrared (NIR) light irradiation. On the one hand, photo-excited charges can rapidly transfer across the homo-heterojunction interface with copper atoms in S–Cu–FC/CuS as both donors and acceptors. On the other hand, the interface between GO and S–Cu–FC/CuS also favors the fast transfer of photogenerated charges. Hence, with the assistance of a photothermal effect, the enhanced photocatalytic performance of S–Cu–FC/CuS/GO endowed the hydrogel with robust sterilization ability for killing 99.5% S. aureus and 100.0% E. coli under 10 min NIR light irradiation. An in vivo test disclosed that this hydrogel could also accelerate the healing of bacteria-infected wounds.

A hydrogen-bond-regulated PVA/CMC quasi-solid-state electrolyte with EG/H 2 O solvent was designed to realize antifreezing and dendrite-free aqueous Zn-ion batteries. • The synergistic polymer network and EG effectively reduced free-water activity, optimized Zn 2+ solvation, and enabled uniform Zn deposition. • COMSOL simulations and experimental analyses confirmed that the quasi-solid-state electrolyte homogenized the interfacial electric field and suppressed dendrite growth. • The Zn||Zn symmetric cell achieved a long cycling lifespan of 1100 h at room temperature and 1700 h at −30 °C. Aqueous zinc-ion batteries (AZIBs) have attracted extensive attention owing to their intrinsic safety, low cost, and environmental benignity. However, the practical application of AZIBs is severely hindered by the freezing of aqueous electrolytes at low temperatures and by uncontrolled Zn 2+ deposition, which induces dendrite growth. Herein, a freeze-resistant quasi-solid-state gel electrolyte is proposed, in which poly (vinyl alcohol) (PVA) and carboxymethyl cellulose (CMC) form a robust three-dimensional network via hydrogen bonding and chain entanglement. Ethylene glycol (EG) regulates the solvation environment by confining free water molecules, thereby depressing the freezing point and stabilizing the Zn 2+ solvation structure, enabling efficient ion transport at low temperatures. COMSOL Multiphysics (COMSOL) further confirms that the quasi-solid-state electrolyte effectively homogenizes the electric field distribution, suppresses dendrite growth, and mitigates interfacial corrosion. Benefiting from these synergistic effects, Zn||Zn symmetric batteries deliver a prolonged cycling lifespan of 1100 h at 1 mA cm –2 and 1 mAh cm –2 , which is 12 times longer than that of the ZnCl 2 electrolyte. Notably, an ultralong lifespan of 1700 h is achieved at -30 °C. Furthermore, the Zn||V 2 O 5 full cell exhibits outstanding cycling stability over 2000 cycles at 1 A g –1 . This work provides a promising strategy for designing antifreezing electrolytes and stabilizing Zn anodes for high-performance AZIBs under extreme conditions.

A Hofmann-degraded HTO/CMC/PVA composite film solves powdered HTO’s solid-liquid separation issue via a dense cross-linked network. • Protonated primary amine groups boost lithium selectivity by nearly twofold through the Donnan exclusion effect. • Superior lithium adsorption in real samples, retaining 91.3% capacity after six adsorption-desorption cycles. Rapid global new energy development fuels explosive lithium demand, with efficient purification of salt lake brine and battery leachate a research hotspot. Liquid-phase lithium recovery is severely hindered by coexisting metal ions with ionic radii similar to lithium, leading to high system complexity. Although powdered H 2 TiO 3 (HTO) lithium ion sieves have inherent advantages of stable structure and excellent adsorption capacity, they face critical technical bottlenecks including low solid-liquid separation efficiency and easy co-adsorption by high-valence interfering ions. To solve these problems, this study modified polyacrylamide (PAM) through Hofmann degradation reaction to introduce primary amine groups, and further compounded modified PAM with carboxymethylcellulose (CMC) and polyvinyl alcohol (PVA) to prepare an HTO-loaded CMC/PVA/PAM composite adsorption film. The film forms a dense cross-linked network via intermolecular hydrogen bonds among the three polymers, fundamentally solving the solid-liquid separation issue of powdered HTO. In an alkaline adsorption environment (pH < 10.5), primary amine groups on modified PAM are protonated to form positive charge sites, which exert the Donnan exclusion effect through electrostatic repulsion to effectively inhibit co-adsorption of magnesium, cobalt, manganese and nickel ions, raising the lithium selective separation efficiency of HTO/CPP2 by nearly twofold compared with HTO/CP. The film showed outstanding specific adsorption performance in actual Da Qaidam Salt Lake water samples and waste battery residue leachate, with good cycling stability that retains 91.3% of the initial adsorption capacity after six cycles. This research thus provides a novel and feasible technical solution for the integrated green extraction of high-purity lithium from two typical complex lithium-containing systems.

Multi-platform analysis identified 184 compounds in Curcuma wenyujin . • An NP-CMC-HPLC strategy was developed for screening antidepressant candidates. • Six potential antidepressant candidates were identified by multi-target screening. • Dihydrocurcumin and furanodienone were highlighted as neuroprotective candidates. • PRM-based quantification supported activity-associated quality evaluation of WYJ. Depression is a complex disorder involving multiple pathological processes, and the identification of bioactive candidates from traditional Chinese medicine (TCM) remains challenging. This study established an integrated network pharmacology (NP)–cell membrane chromatography (CMC)-high-performance liquid chromatography (HPLC) strategy (NP-CMC-HPLC) for activity-guided screening of potential bioactive compounds and activity-associated quality characterization of the dried tuberous root of Curcuma wenyujin Y. H. Chen & C. Ling (WYJ). The chemical profile of WYJ was comprehensively characterized using ultra-performance liquid chromatography coupled with quadrupole Orbitrap mass spectrometry (UPLC-Q-Orbitrap-MS), combined with headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC-MS) and headspace gas chromatography-ion mobility spectrometry (HS-GC-IMS). A total of 184 compounds were identified, and potential bioactive compounds were prioritized through network pharmacology analysis. Multi-target cell membrane chromatography (CMC) systems based on 5-hydroxytryptamine 1 A receptor (5-HT 1A ), 5-hydroxytryptamine 2 A receptor (5-HT 2A ), dopamine D1 receptor (DRD1), dopamine D2 receptor (DRD2), and monoamine oxidase A (MAO-A) were subsequently established, enabling the identification of six compounds exhibiting target-associated retention behavior. Molecular docking and a corticosterone-induced PC12 cell injury model provided complementary computational and cellular evidence supporting compound selection. Finally, a parallel reaction monitoring (PRM)-based method was developed for the quantitative analysis of four non-volatile CMC-prioritized compounds. The proposed strategy integrates chemical profiling, target affinity screening, cellular evaluation, and quantitative analysis to facilitate the discovery of bioactive candidates and activity-associated quality characterization of complex herbal medicines.

Conductive hydrogels possess excellent flexibility and tunable conductivity, making them promising materials for flexible strain sensor and triboelectric nanogenerator (TENG). However, conventional conductive hydrogels suffer from low mechanical strength, toxic crosslinkers, and poor recyclability. In this study, a lignosulfonate (LS)-Fe 3 + autocatalytic system was utilized to rapidly initiate the polymerization of polyacrylic acid (PAA). In addition, carboxymethyl cellulose (CMC) was incorporated to reinforce mechanical strength, while ethylene glycol (EG) was introduced to improve antifreezing and moisturizing properties. The resulting PCL-EG hydrogel was employed to fabricate flexible strain sensor and triboelectric nanogenerator. This hydrogel exhibits outstanding adhesion, self-healing ability, and recyclability. The PCL-EG hydrogel-based strain sensor exhibits a wide detection range and high sensitivity (GF = 13.3 at 300–500 % strain), enabling reliable monitoring of human motion across multiple body regions. Furthermore, TENG assembled with the PCL-EG hydrogel generate stable electrical output, sufficient to power small wearable electronics and support self-powered signal transmission. This work offers valuable insights and guidance for the development of multifunctional flexible electronic devices.

This study employed β-cyclodextrin (β-CD) for the hydrophilic modification of iron tetraoxide (Fe3O4) magnetic materials. Subsequently, potassium humate (KHA) and carboxymethyl cellulose (CMC) were used as raw materials. A β-CD@Fe3O4/KHA/CMC/AM/MAH hydrogel with magnetic properties which can be easily recycled was synthesized for the slow release of glyphosate (GLY). FTIR, XRD, TG and VSM analyses demonstrated that the hydrogel possesses good thermal stability and magnetic properties with a saturation magnetization strength of 29.77 emu g−1. The equilibrium solubility of the hydrogel in pH = 7.4 and pH = 8.5 buffer was 24.58 g g−1 and 25.83 g g−1, respectively. The maximum release of GLY was recorded at 63.31% and 67.78%, with the drug release behavior under different loading gels following the Fickian diffusion mechanism. A pot planting experiment indicated that the water content of plants treated with the β-CD@Fe3O4/KHA/CMC/AM/MAH drug-loaded gel decreased by 51.69%. Additionally, soluble protein levels decreased to 2.69 mg g−1, chlorophyll content decreased to 0.486 mg g−1, SOD levels decreased to 43.81 U g−1, and MDA increased to 4.02 μmol g−1, effectively inhibiting the growth of grass and providing a theoretical basis for achieving slow drug release.
