Corn oil, sodium carboxymethyl cellulose (CMC-Na), and dimethyl sulfoxide (DMSO) are widely used as solvents or suspensions in animal experiments, but the effects of prenatal exposure to them on fetal development have not been reported. In this study, Kunming mice were given a conventional dose of corn oil (9.2 g/kg·d), CMC-Na (0.05 g/kg·d) or DMSO (0.088 g/kg·d) during gestation days 10–18, and the pregnancy outcome, fetal physical development, serum phenotype, and multi-organ function changes were observed. The results showed that corn oil decreased serum triglyceride level in males but increased their serum testosterone and CORT levels, and affected female placenta and female/male multi-organ functions (mainly bone, liver, kidney). CMC-Na increased female/male body lengths and tail lengths, decreased serum glucose and total cholesterol levels in males as well as increased their serum LDL-C/HDL-C ratio and testosterone level, decreased female serum bile acid level, and affected male/female placenta and multi-organ functions (mainly bone, liver, hippocampus). DMSO decreased male body weight and serum glucose level, decreased male/female serum bile acid levels, and affected male/female placenta and multi-organs functions (mainly bone, hippocampus, adrenal gland). In conclusion, prenatal exposure to a conventional dose of corn oil, CMC-Na or DMSO could affect fetal physical development and multi-organ functions, and has the characteristics of "multi-pathway, multi-organ and multi-target". This study provides the experimental basis for the rational selection of solvents or suspensions in pharmacology and toxicology studies.

In this work, an efficient Fe 3+ adsorbent was synthesized by using the tryptamine and sodium carboxymethyl cellulose (CMC-Na) modified polyacrylamide gel. The functional monomers synthesized by the reaction of tryptamine and methacrylic acid chloride were doped into the composition, and CMC-Na participated in the formation of the gel network. By changing different conditions, the optimal use conditions of the gel were explored. The Langmuir and Freundlich isotherm models were used to discuss the adsorption behavior. According to the fitting results, the Freundlich model was more suitable for explaining the adsorption of Fe 3+ by gels. The feasibility of its adsorption process was confirmed by the study of its kinetics and thermodynamics. As an adsorbent, tryptamine CMC-Na modified polyacrylamide gel has excellent ability to remove Fe 3+ from aqueous solutions. The maximum adsorption capacity of tryptamine and CMC-Na modified polyacrylamide gel for Fe 3+ reached 127.5 mg g −1 .

Graphical In order to improve the stability and controlled release properties, NaClO 2 is microencapsulated based on emulsion crosslinking method adopting high biocompatibility sodium alginate (SA) and sodium carboxymethyl cellulose (CMC-Na) as shell material. The resulted sample is featured with selectivity and no secondary pollution, and brings about continuous degrading both liquid and gaseous formaldehyde. Sodium chlorite (NaClO 2 ) is a new type of air disinfectant, which can oxidize formaldehyde into carbon dioxide (CO 2 ) on account of releasing chlorine dioxide (ClO 2 ) gas under acidic condition. Unfortunately, NaClO 2 is prone to moisture absorption and decomposition when exposed to air. In this paper, NaClO 2 was microencapsulated based on emulsion crosslinking method for improving its stability and controlled release properties. Due to their high biocompatibility, sodium alginate (SA) and sodium carboxymethyl cellulose (CMC-Na) were selected as the wall material to prepare NaClO 2 -SA/CMC-Na composite microcapsules. The results showed that mean particle size of NaClO 2 -SA/CMC-Na composite microcapsules was about 225 nm, and their encapsulation ratio was up to 73.18%. In addition, the thermal stability and environmental tolerance of NaClO 2 are improved greatly through microencapsulating. It was proved by formaldehyde degradation testing that the efficiency of formaldehyde degradation using resulted samples can continue to increase after seven days in pH 6.5 environment, indicating their good controlled-release performance. Moreover, degradation efficiency on 30 µg/mL formaldehyde solution using the resulted microcapsules is up to 97.08%. Meanwhile, after 20 repetition degradation, NaClO 2 -SA/CMC-Na composite microcapsules can still continuously degrade formaldehyde gas. Therefore, NaClO 2 -SA/CMC-Na composite microcapsules reveal good stability and prolonged action on formaldehyde degradation.

Removal of copper ions (Cu(II)) efficiently from water is crucial for water environment security. We use sustainable, low-cost, renewable cellulose derivatives (carboxymethylcellulose sodium (CMC-Na)) and polyvinyl alcohol (PVA) as the matrix, and cellulose nanocrystals (CNCs) as the functional addition. The CNC/CMC-Na/PVA hydrogel was prepared by the physical cross-linking method. Static adsorption experiments proved that CNC/CMC-Na/PVA hydrogel has a greater adsorption potential (108 mg/g) towards Cu(II). At the same time, the adsorption of Cu(II) on CNC/CMC-Na/PVA hydrogels is spontaneous and endothermic, and obeys the pseudo-second-order model with intra-particle diffusion. Furthermore, the primary adsorption mechanisms had been electrostatic attraction and surface complexation. Importantly, CNC/CMC-Na/PVA hydrogel has efficient absorbability and preferable reusability in actual water samples. Furthermore, the copper nanoparticles (Cu NPs) adsorbed on the surface of CNC/CMC-Na/PVA hydrogels were reduced with NaBH 4 in situ to realize the secondary utilization in CNC/CMC-Na/PVA hydrogels supported by Cu NPs. It is found that the material can be used as a catalyst to efficiently catalyze the conversion of HMF to BHMF (99%). Consequently, we provide insights into the hydrogel preparation that would possibly be promising novel adsorbents for the elimination of heavy-ion from sustainable water purification.

Electrochemical mechanical polishing (ECMP), through the introduction of electric field, promotes the chemical reaction during polishing. However, the addition of electric field will accelerate the oxidative corrosion, at this time the effective corrosion inhibitor must be added in the polishing solution. Nevertheless, most traditional corrosion inhibitors are toxic and inhibition efficiency is low. In order to meet this technical challenge, this paper investigates the effect of two green corrosion inhibitors, chitosan oligosaccharide (COS) and carboxymethylcellulose sodium (CMC-Na), on Co ECMP, and compares them with the traditional inhibitor TAZ. The results show that when COS and CMC-Na are added at the same time, the polished Co surface quality can be greatly improved, and the surface roughness decreases by 94.6 %. It indicates that adding COS and CMC-Na simultaneously can play the best corrosion inhibition effect and achieve the best surface quality. The synergistic behavior and action mechanism of COS/CMC-Na are analyzed by polishing experiments, static corrosion, electrochemical tests, XPS, and AFM. This study provides a reference for the development of green polishing solutions for Co ECMP.

Materials integrating electromagnetic interference (EMI) shielding and infrared (IR) stealth possess great application potential but face obstacles in large-scale production. Herein, MXene/sodium carboxymethyl cellulose (CMC-Na) composite ink is synthesized via facile, scalable vacuum ball milling. CMC-Na chains adhere to MXene through intermolecular hydrogen bonds; electrostatic repulsion restrains nanosheet stacking, while the coating hinders MXene oxidation. The ink exhibits outstanding machinability and can form uniform films on various substrates via screen printing or coating. At a MXene/CMC-Na mass ratio of 4:1, the film achieves balanced performance: a tensile strength of 82.84 MPa, an elongation at break of 2.67%, a toughness of 1.58 MJ·m – 3 , an EMI shielding effectiveness of 33 dB, and a specific shielding effectiveness of 37,260 dB·cm 2 ·g –1 . Low IR emissivities of 19.56% (3–5 μm) and 13.65% (8–14 μm) reduce the surface radiant temperature to 69 ° C under 150 ° C heating. Its layered structure combines surface and internal multiple reflections to reconcile EMI shielding and IR stealth. This low-cost scalable strategy supports the development of integrated shielding-stealth wearable electronic devices.

Flexible humidity sensors with excellent flexibility and sensitivity have been widely used in various fields such as human and plant health monitoring and management, non-contact human-machine interaction, smart e-textiles, and industrial and agricultural production. However, many sensors are limited their application due to the problems of unbreathable and poor wear comfort. Herein, a highly sensitive humidity sensor based on flexible polyester fabric with directional moisture transport is proposed. The facile method of coating is conducted by the preparation of poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) and sodium carboxymethylcellulose (CMC-Na) paste with adjustable content and applied to the polyester fabric. The difference of hydrophilicity between the two sides of the fabric caused by the coating helps to directional moisture transport, thus giving rapid sensitivity, while using PEDOT: PSS can obtain the changes of electrical conductivity coming from the humidity. and the addition of CMC-Na not only helps the coating, but also provides hydrophilic groups, which is conducive to humidity sensing and directional moisture transport. The combination of this moisture-sensitive coating and directional moisture transport gives the sensor a fast humidity response time of 0.35 s, a wide humidity detection range (0‐100%(0–100% RH) and sensitivity of 4.15. Furthermore, the sensor can maintain the humidity response time in milliseconds even after being subjected to water washing and friction, indicating its excellent durability and stability.

To overcome critical challenges in flexible aqueous zinc-ion batteries (AZIBs)—specifically zinc dendrite proliferation, recurrent side reactions, and electrolyte mechanical-electrochemical incompatibility—we engineered a hydrogel electrolyte (PZEC). Synthesized in one step, PZEC integrates polyacrylamide (PAM)/ZnSO₄ with synergistic enhancements from ethylene glycol (EG)-based deep eutectic solvent (DES) and sodium carboxymethyl cellulose (CMC Na). A synergistic multi-component modification strategy reconstructing the hydrogen bond network yielded concurrent, major gains in mechanical strength and electrochemical stability. Hydrogen bond deconvolution analysis revealed a 3.1 % increase in strong hydrogen bonds within PZEC, accompanied by a significant reduction in the phase transition temperature to −29.46 °C, indicative of enhanced bound water confinement and low-temperature adaptability. PZEC manifests excellent mechanical properties (90 kPa fracture stress, 1280 % elongation) while attaining high ionic conductivity (29.26 mS·cm −1 ) and zinc ion transference number (0.63) via zinc solvation sheath compression and guided ion transport. The Zn//Zn symmetric battery exhibited exceptional cycling endurance, operating for 700 h at 5 mA·cm −2 and over 2000 h at 0.5 mA·cm −2 . Notably, PZEC maintained superior rate performance and cycling stability at 0 °C, retaining high reversible capacity and near-100 % coulombic efficiency (CE) even under high-rate conditions. Consequently, this work outlines a new methodology for high-performance flexible AZIBs and delivers significant insights for hydrogen bond-functionalized electrolyte engineering.

Aeromonas sobria , recognized as a psychrotrophic specific spoilage organism in refrigerated aquatic products, facilitates its proliferation by metabolizing proteins, lipids, and carbohydrates, thereby generating spoilage-associated metabolites and compromising product quality. Quorum sensing (QS), a bacterial cell-to-cell communication mechanism, orchestrates the secretion of virulence and spoilage factors in A. sobria via the LuxI/R QS system. Targeting this regulatory pathway presents a novel strategy to mitigate spoilage and extend the shelf life of aquatic products. Previous studies have demonstrated that zingerone (ZRN) exhibits quorum-quenching activity at sub-inhibitory concentrations; however, its practical application is constrained by limited solubility and bioavailability. To overcome these challenges, ZRN was encapsulated within halloysite nanotubes (HNTs) and incorporated into a self-assembled composite film composed of chitosan (CS) and sodium carboxymethyl cellulose (CMC-Na). The fabricated film was characterized for its structural, thermal, and mechanical properties and subsequently evaluated for its preservation efficacy on refrigerated perch fillets. The composite film exhibited a homogeneous surface morphology with uniformly dispersed HNTs, alongside adequate thermal stability, tensile strength, and physicochemical attributes suitable for refrigerated aquatic product preservation. Notably, the film suppressed spoilage indicators, including total volatile basic nitrogen (TVB-N) accumulation, lipid peroxidation, and bacterial spoilage potential, without inhibiting A. sobria growth. Furthermore, it mitigated muscle tissue degradation and biogenic amine formation in perch fillets during refrigerated storage. Molecular docking simulations revealed that ZRN competitively binds to the LuxR-type receptor at the same binding pocket as the endogenous autoinducer C 4 -HSL, thereby disrupting QS signaling. Collectively, this ZRN-loaded composite film represents a promising biodegradable packaging solution for enhancing the quality and shelf life of refrigerated aquatic foods.

In this study, cellulose-based superabsorbent hydrogel was synthesized from sodium carboxymethyl cellulose (CMC-Na), acrylic acid (AA), and 2-acrylamido-2-methylpropanesulfonic acid (AMPS) to enhance its water absorbency and salt tolerance for soil-conditioning applications in areas suffering from drought and soil salinization. Superabsorbent hydrogels (SHs) were prepared by CMC-Na and AMPS successfully, using chemical graft technology. Structure, morphology, thermal stability , and water absorbency of SHs were deduced. The cellulose-based hydrogel showed a high salt tolerance that the maximum water absorbency reached 604 and 119% in distilled water and saline water, respectively. The swelling behavior in aqueous solvents indicated that the water absorption of hydrogels was improved with the increasing ratio of CMC-Na. All SHs exhibited adsorption of nitrogen with the maximum adsorption of ammonia nitrogen 30 mg·g −1 and the presence of hydrogels could slow down the loss of nutrients in the soil. This study provided a feasible strategy that AMPS was substituted by CMC-Na to synthesize SHs with strong water absorbency and high salt tolerance which could be efficiently applied in agriculture as a soil conditioner.
