To enhance ablation resistance in (Ta₀.₂Nb₀.₂Ti₀.₂Hf₀.₂Zr₀.₂)C–SiC (HEC–SiC) ceramics, the influence of SiC particle size on microstructure and ablation behavior was examined. With the addition of 20 wt% fine SiC particles, its relative density increases from 91.23% to 97.79%, and the grain size of the HEC phase decreased from 3.58 to 0.79 μm. The fine SiC particles facilitated the formation of a continuous SiC network, thereby enhancing the thermal conductivity from 6.94 to 22.35 W/mK. This enhanced thermal conductivity contributed to reducing the ablation temperature from 2358 to 1721 °C during the ablation. The HEC-SiC sample with 0.5 μm fine SiC particles added exhibits a mass and linear ablation rate of 0.05 mg/s and 0.67 µm/s. The superior ablation resistance can be attributed to the reduced ablation temperature, altering the preferential oxidation sequence. This change in preferential oxidation led to the formation of a compact oxide scale with a multi-layer structure.

A cellulose-based hydrogel with synergistic therapeutic effect was prepared by a one-pot method. The hydrogel had hydroxyethyl cellulose (HEC) as a framework and epichlorohydrin (EPI) as a cross-linking agent. Cationic-β-cyclodextrin (C-β-CD) was homogeneously embedded in the grid of the cross-linked structure. Zinc oxide nanoparticles (ZnO NPs) and menthol were used to provide analgesic and bactericidal effects . Menthol was uniformly loaded onto the hydrogel matrix by the addition of C-β-CD and increased the solubility of menthol in water. ZnO NPs were synthesized by in situ hydrothermal treatment . The positively charged group of C-β-CD and the active hydroxyl group of HEC were used to distribute the ZnO NPs uniformly on the hydrogel matrix without significant agglomeration. The hydrogel had a smoothly ordered and compact morphology. It exhibited adequate mechanical, swelling, water retention and oxygen permeability properties in tests. In addition, the hydrogel had an efficient bactericidal effect. Release experiments showed that the encapsulation of menthol by C-β-CD allowed for a slow release of menthol. Biocompatibility tests had shown that the hydrogel was non-toxic to normal human cells.

Injectable thermosensitive hydrogels have been widely investigated as minimally invasive scaffolds for three-dimensional (3D) cell culture. In this study, we systematically screened a chitosan (CS)/β-glycerophosphate (β-GP)/hydroxyethyl cellulose (HEC) ternary hydrogel system using a 2 × 2 × 2 factorial design. By evaluating gelation kinetics, injectability, and structural stability through a weighted scoring model, two superior formulations (G1 and G3) were selected for their ability to balance rapid gelation at 37 °C with reliable room-temperature injectability. Subsequent biological evaluations demonstrated that, compared to conventional 2D cultures, the 3D hydrogels supported robust cellular viability and spatial proliferation through Day 10. The stable biomimetic matrix provided essential physical anchorage, enabling Huh7 cells to self-assemble into dense tumor spheroids and BMSCs to establish spatial networks. This study presents a structured formulation-screening strategy and demonstrates the effectiveness of the CS/β-GP/HEC hydrogel as a reliable platform for in vitro 3D cell culture applications.

In this study, hydroxyethyl cellulose (HEC) was cross-flow deposited on flat-sheet polypropylene (PP) porous support and insolubilized by cross-linking using glutaraldehyde (GA) to fabricate cost-effective thin-film composite membrane for aqueous and non-aqueous nanofiltration. Membrane physico-chemical property, permeation performance, as well as tolerance to acid, alkaline and organic solvents were systematically characterized. The obtained HEC/PP composite membrane was found to be effectively modulated in pore size via changing HEC and GA contents and possessed good fabrication reproducibility. The desired HEC/PP composite membrane with an average pore diameter of around 2.21 nm exhibited high fluxes of 41.0 and 8.2 L/m 2 h to pure water and ethanol, respectively, and removals of 99.9%, 99.9% and 96.7% to 50 mg/L dye aqueous solutions of methyl blue, Congo red and sunset yellow, respectively. Soaking tests revealed that the HEC/PP composite membrane possessed good tolerance to acid, alkali and organic solvents of tetrahydrofuran, ethyl acetate and ethanol. Continuous filtration of dye/ethanol solution demonstrated that the HEC/PP membrane possessed excellent long-term durability in ethanol solution, maintaining a stable flux higher than 4.6 L/m 2 h and removals of 95.4% and 84.2% to methyl blue and Congo red, respectively, during the whole filtration of 110 h.

For food packaging, a novel composite film was prepared by solution casting method using hydroxyethyl cellulose (HEC), carboxymethyl chitosan (CMCS), and zinc oxide nanoparticles as raw materials. The composite film successfully compounded the nanoparticles, as deduced by spectroscopy, crystallography and morphology observation. The addition of CMCS and ZnO enhanced the solvent resistance (the water solubility of the composite film was reduced by 94.3 %) and UV shielding ability (the UV shielding capacity of the composite film was increased by 45.73 %) of the composite film, thus improving the application prospects of the composite film in water-rich foods. In addition, the synergistic effect of CMCS and ZnO helped the composite film to efficiently inhibit the pathogenic bacteria Listeria monocytogenes and Pseudomonas aeruginosa (rate of inhibition>99.99 %) in food. The addition of CMCS and ZnO also significantly improved the elasticity (improve 494.34 %) and maximum load capacity (improve 142.24 %) of the composite film.

As an inorganic phase change material (PCM), CaCl 2 ·6H 2 O is an effective energy storage material because its energy can be transformed around 30 °C through the melting and crystallization. The different compositions of PCM were prepared in order to decrease the phase transition temperature to 20–25 °C and to improve its capability of heat storage and release. MgCl 2 ·6H 2 O was added as a nucleating agent and the composite PCMs (CPCMs) of CaCl 2 ·6H 2 O/MgCl 2 ·6H 2 O binary salt system was prepared. At the same time, SrCl 2 ·6H 2 O was added to reduce the supercooling degree of inorganic PCM. As a thickener, hydroxyethyl cellulose (HEC) was also included to improve the recycling ability. With the application of thermogravimetric analysis and differential scanning calorimeter, the phase transition temperature, thermal properties of CPCMs, supercooling degree and thermal cycle performance were studied by changing the content of each component in the CPCMs. The results demonstrated that the phase transition temperature of PCM with 35% MgCl 2 ·6H 2 O, 5% SrCl 2 ·6H 2 O, 0.5% HEC balanced by CaCl 2 ·6H 2 O was reached to 23 °C. The phase change latent heat of PCM was kept at 130 J/g. The degree of supercooling was kept within 0.7 °C and the recyclability was greatly improved after 100 cycles.

Emulsifiers based on amphiphilic cellulose are typically created by adding a hydrophobic group to hydrophilic cellulose. There are few reports on the use of rigid large skeleton structures as hydrophobic groups in the modification of hydrophilic cellulose. This study investigated the hydrophobic rosin (DAGE, containing a large rigid hydrogenated three-phenanthrene ring) modified hydroxyethyl cellulose (HEC), and it was applied to stabilize emulsion gels as an emulsifier (DAGE-g-HEC). DAGE-g-HEC was successfully prepared and DAGE-g-HEC (I–V) were obtained with different grafting degrees ranging from 34.65 % to 46.20 %. In terms of lowering water surface tension, DAGE-g-HEC demonstrated greater activity than HEC, and the γ CMC was about 36.00 mN/m. DAGE-g-HEC stabilized emulsion gels with 80 % oil phase showed that emulsion stability remained for more than six months at 0.05 wt% or above 0.05 wt% DAGE-g-HEC concentration due to the tight interfacial films established by the rigid group of rosin. The rheological property showed that as the DAGE-g-HEC concentrations rose, so did the emulsions' apparent viscosity. All emulsion gels exhibit strong elastic behavior, according to the loss tangent (tan δ = G″/G′) evolutions.

Graphical An open liquid plasticine-based FASS system (FASS: field-amplified sample stacking) for protein enrichment was developed, with which proteins can be enriched 40–80-fold by LP-FASS within 40 min. Protein analysis is an important approach for disease diagnosis, in which sample pretreatment is an essential step since protein samples are often complex and many protein biomarkers are of low abundance. Here, given the good openness and light transmission of liquid plasticine (LP), which is a liquid entity formed by SiO 2 nanoparticles and encapsulated aqueous solution, we developed a LP-based field-amplified sample stacking (FASS) system for protein enrichment. The system was composed of a LP container, a sample solution and a Tris-HCl solution containing hydroxyethyl cellulose (HEC). The system design, mechanism investigation, optimization of experimental parameters and characterization of LP-FASS performance for protein enrichment were well studied. Under the optimized experimental conditions of 1 % HEC, 100 m m Tris-HCl and 100 V in the LP-FASS system, a 40–80 times enrichment of proteins was obtained in 40 min using bovine hemoglobin (BHb) as the model protein using the constructed LP-FASS system. The simultaneous enrichment of multiple proteins (phycocyanin, BHb and cytochrome C) was also realized using the system. The LP-FASS system can serve as a new platform for protein enrichment which is easy to be combined with online and offline detections.

Perovskite solar cells (PSCs) have been demonstrated to be one of the most promising technologies in the field of renewable energy. However, the presence of the defects in the perovskite films greatly limits the efficiency and the stability of the PSCs. The additive engineering is one of the most effective approaches to overcome this problem. Most of the successful additives are extracted from the petroleum-based materials, while the research on the biomass-based additives is still lagging behind. In this paper, two ecofriendly hydroxyalkyl cellulose additives, i.e., hydroxyethyl cellulose (HEC) and hydroxylpropyl cellulose (HPC), are investigated on the performance of the MAPbI 3 -based inverted PSCs. Due to the strong interaction between the hydroxyl groups of the cellulose and the divalent cations of the perovskite, these additives enhance the crystal grain orientation and significantly repair the defects of the perovskite films. Working as the additives, these two cellulose derivatives show a strong passivation ability, which significantly reduces the trap density and improves the optoelectronic feature of the PSCs. Compared with the average power conversion efficiency (PCE) of the control device (19.19%), an enhancement of ~10% is achieved after the addition of HEC. The optimized device (PCE = 21.25%) with a long-term stability (10:80 h, PCE = 20.93%) is achieved by the incorporation of the HEC additives into the precursor solution. It is the best performance among the PSCs with the cellulose additives up to now. This research provides a novel choice to develop a cost-effective and renewable additive for the PSCs with high efficiency and excellent long-term stability.

By preparing Cu@CuO aerogel as a nanozyme which exhibits prominent peroxidase-like (POD) activity, an innovative homogeneous electrochemistry (HEC) coupled with the colorimetry dual-model sensing strategy is proposed to detect perfluorooctane sulfonate (PFOS) for the first time. Cu@CuO aerogel accelerates the oxidation process of colorless o-phenylenediamine to form yellow 2,3-diaminophenazinc (DAP), and meanwhile, DAP as an electroactive substance creates a reduction peak current upon the electrochemical measurements. Interestingly, in the presence of PFOS, the POD activity of Cu@CuO aerogel is inhibited since the specific coordination between PFOS and Cu(II) can cover the active sites, resulting in the color of the sensing system becoming light and the peak current of DAP decreasing. This innovative dual-mode detection method showed excellent electrochemical detection of PFOS in the concentration range 10.0 ~ 1125.0 nM with a limit of detection (LOD) as low as 3.3 nM and a LOD of 20.8 nM in the colorimetric detection in the range 62.3 ~ 875 nM. Furthermore, the sensor was successfully used for the analysis of real samples with an RSD value ≤ 6.5%. The successful application of this two-mode sensing method for the determination of PFOS holds promise for the detection of other contaminants in the future. Graphical Abstract

Achilles tendon sleeve avulsions often involve tissue defects. Standard bone tunnel fixation risks tunnel enlargement, inflammation, and graft failure. Native tendon and bone tissue exhibit inherent bioelectrical properties whose disruption impedes healing. To address these, the study developed electroactive, anti-inflammatory sutures featuring a strong polylactic acid (PLA) micron yarn core and a conductive poly(3,4-ethylenedioxythiophene)/hydroxyethyl cellulose/glycerol/chondroitin sulfate/PLA (PEDOT/HEC/glycerol/CS/PLA) nanofibrous shell. A novel synthesis strategy enabled EDOT polymerization templated by HEC, eliminating the need for poly(styrene sulfonate) (PSS), oxidants, or catalysts and allowing direct electrospinning. In vitro, it can regulate macrophage polarization and enhance tenocytes and bone marrow mesenchymal stem cell (BMSCs) proliferation and differentiation. In a rabbit Achilles tendon avulsion model, the suture enables secure tendon-to-bone fixation via calcaneal bone tunnels. At 12 weeks post-operation, the suture exerts anti-inflammatory effects by modulating CD206/CD86 expression. Electroactive suture significantly enhances tendon regeneration and bone formation within the tunnels, and achieves robust tendon-to-bone integration at the interface, markedly improving fixation stability. In summary, this electroactive, anti-inflammatory suture effectively promotes tendon-bone regeneration for repairing Achilles tendon sleeve avulsions.

GO/HEC/PGDE/Fe 3 O 4 materials were successfully fabricated using environmentally-friendly hydroxyethyl cellulose (HEC), poly(ethylene glycol) diglycidyl ether (PGDE), graphene oxide (GO) and magnetic Fe 3 O 4 . Systematic investigations were completed to explore the influences of GO content in GO/HEC/PGDE/Fe 3 O 4 and adsorption conditions on the adsorptions of cationic dyes (methylene blue (MB), crystal violet (CV)) and anionic dye acid blue 25 (AB-25). The increase of GO content can remarkably improve the adsorption capacity of GO/HEC/PGDE/Fe 3 O 4 for the dyes. The three kinetic, four isothermic and three thermodynamic models were investigated to reveal the adsorption behaviors of the dyes. The formation of HEC/PGDE/Fe 3 O 4 and adsorption mechanisms of the dyes by GO/HEC/PGDE/Fe 3 O 4 were suggested. The GO/HEC/PGDE/Fe 3 O 4 endowed with easy-fabrication, eco-friendly feature, efficient adsorption capacity of anionic/cationic dyes, convenient separation and reusability has potential applications in wastewater purification industry.
