Inspired by natural biomineralization, high-performance pervaporative desulfurization membranes were engineered through a one-step synthesis strategy. Cysteamine served as both an inducer and catalyst, steering the deposition of silica (SiO 2 ) onto graphene oxide (GO) nanosheets that were pre-dispersed in a polydimethylsiloxane (PDMS) matrix. The Fourier transform infrared spectroscopy and x-ray diffraction results demonstrated that in situ-formed SiO 2 was attached firmly onto the GO sheets. The scanning electron microscopy results showed that the GO/SiO 2 fillers were uniformly dispersed in the PDMS matrix. The incorporation of GO/SiO 2 within the lipophilic PDMS matrix markedly enhanced the desulfurization performance of the resultant biomineralized membranes. The fabricated membranes were evaluated for the separation of thiophene from an n -octane/thiophene mixture by pervaporation. It was demonstrated that the membrane displayed high selectivity towards thiophene. The sulfur enrichment factor reached a maximum of 6.30 for the biomineralized membrane containing 0.3 wt% GO, accompanied by a permeation flux of 6973 g m −2 h −1 in a 1312 ppm thiophene/ n -octane mixture at 303 K. The desulfurization performance of the biomineralized membranes maintained practically constant over 168 consecutive hours, displaying long-term stability. This facile one-step strategy offers a readily scalable route to fabricate high-performance pervaporative membranes for deep gasoline desulfurization.

Introducing uniform, stable, and small pores by adding air-entraining agents (AEAs) is an effective strategy for improving the freeze–thaw resistance and workability of cement concrete materials. In this study, the gelatin with hydrophobic and hydrophilic functional groups was used as an AEA for cement concrete materials and systematically studied its effect on the performance of cement mortar specimens. The results showed that gelatin has a surfactant-like function and can effectively reduce the surface tension of the gas–liquid interface. In an alkaline environment, Ca 2+ ions in cement pore solution chelate with carboxylate ions formed by carboxyl ionization, further enhancing the performance of gelatin-based AEAs. Thanks to the reduction in surface activity and carboxyl ionization, introducing gelatin increased the porosity of cement mortar specimens from 0.53% to 2.69%. Furthermore, introducing an appropriate amount (>0.1 wt%) of gelatin does not significantly impact the workability or mechanical properties of cement mortar. Based on these characteristics, gelatin has potential as an AEA for cement concrete materials.

In the process of unconventional oil and gas exploitation, the invasion of a large amount of drilling fluid into the formation is one of the most critical reasons leading to wellbore instability. A temperature-sensitive polymer (AOS) was synthesized from acrylamide, oligo (ethylene glycol) methyl ether methacrylate (OEGMA), and sodium p-styrene sulfonate by emulsion polymerization. The material is a solid-free fluid with good fluidity at room temperature, after injection into the formation, the fluid is gradually transformed into hard gel above the lower critical solution temperature (LCST) (90°C), thus blocking micro-fractures and improving wellbore stability. Infrared and NMR characterization confirmed the successful preparation of the target product. The transmittance of AOS with ambient temperature was measured by UV–vis spectrophotometer, and the LCST behavior of AOS was verified by rheological and viscoelastic measurements. The interaction mechanism between AOS and sodium bentonite was evaluated according to the American Petroleum Institute standard. The results show that after aging at 180°C, the filtration loss is reduced by 93%, and the medium permeability (100, 200 mD) formation is effectively plugged, with a plugging efficiency is as high as 74.7%.

External plasticization is one of the effective ways to toughen epoxy resins. In this study, an inorganic filler (EMD) was prepared by chemical modification of diatomite and was used to fill epoxy resin matrix. The effects of different amounts (5%, 10%, 15%, and 20%) of raw diatomite (RD) and modified-diatomite (EMD) on the mechanical and thermal properties of epoxy resin composites were studied. The mechanical results showed that the impact strength, tensile strength, and bending strength of EMD/EP were higher than those of RD/EP. The impact strength of EMD-15/EP reached 5.39 KJ/m 2 , which was 36.8% higher than that of RD-15/EP. Thermogravimetric analysis showed that the thermal stability of EMD/EP was better than that of RD/EP. The results of DMA show that the glass transition temperature of EMD/EP was lower than that of RD/EP. Non-isothermal differential scanning calorimetry study showed that the apparent activation energy of EMD-15/EP was much lower than that of RD-15/EP, which proved that EMD could promote the curing of epoxy resin. The Malek method was used to determine that both the RD-15/EP and EMD-15/EP curing systems were autocatalytic (Šesták–Berggren) models.

Nanoformulation was an important strategy to reduce the use of pesticides and the impacts on the environment. However, complex process and high cost hurdled the application in agriculture. In this work, sodium lignosulfonate (SL) and cetyltrimethyl ammonium chloride (CTAC) were combined into nanoparticles and utilized as carriers for emamectin benzoate (EB), using a one-pot method at mild conditions. The structure of nanoparticle was investigated by dynamic light scattering, ζ-potential measurement, Fourier transform infrared spectroscopy, and transmission electron microscopy, and related to the loading and release properties. The mass ratio of SL and CTAC had great impacts on the structure of nanoparticle. The release of EB from SL-CTAC nanoparticles was pH-triggered. The retarding efficacy was enhanced in the medium of higher pH, due to the increased interaction between the EB and carrier. The incorporation into the nanoparticles greatly increased the insecticidal toxicity of EB. The median lethal concentration, against Spodoptera litura Fabricius larvae , of typical nanoformulation was 55% and 63% of that of conventional formulation emulsifiable concentrates after feeding for 24 and 48 h, respectively. The results indicated SL-CTAC nanoparticles were good candidates of nanovehicles with high efficiency and low-cost, which was of great significance to prompt the nanopesticides from laboratory investigation to agricultural application.

This study presents the development of a biodegradable composite scaffold designed to address the limitations associated with conventional bone repair materials. 3D-printing filaments were developed using fish scale powder (FSP) or fish scale-derived hydroxyapatite (HAP), polylactic acid (PLA), and polycaprolactone (PCL), with a focus on the optimal effect of 5 wt% HAP on the mechanical properties of PLA. Composite scaffolds were further prepared by integrating 3D-printed grid scaffolds with chitosan/gelatin composite hydrogels through vacuum freeze-drying. The properties of the composite scaffolds were evaluated through mechanical property tests, thermal analysis (including DSC and TGA), absorption rate assessments (conducted via immersion experiments in various solutions), and surface morphology analyses (utilizing SEM and EDS). The results show that the addition of HAP significantly improves the mechanical properties of 3D-printed filaments. The high absorption rate exhibited by the HAP/PLA composite scaffold suggests improved biocompatibility and its potential for in vivo tissue fluid absorption. The HAP/PLA composite scaffold showed visible surface mineralization and degradation after 10 days of immersion in simulated body fluid (SBF), highlighting its potential for bone repair and regeneration.

The development of conductive scaffolds has emerged as a promising strategy to enhance cell proliferation and differentiation by leveraging the electrical properties of biomaterials to stimulate cellular behaviors. This study initially prepared polypyrrole-modified Silk Fibroin (PPy/SF) composite scaffolds by in situ polymerization of PPy on SF fibers through electrospinning and in situ interface polymerization methods. The results demonstrated that modification of PPy can improve the thermal stability of SF and mechanical strength. Cytotoxicity experiments showed that the PPy/SF nanofiber scaffold has good cytocompatibility. PPy modification significantly enhanced the conductivity of SF scaffolds and promoted the proliferation and migration of PC-12 cells at 200 mV. The findings of this study will provide significant scientific evidence for the development of bioactive materials for promoting the proliferation and differentiation of biological cells and wound healing.

Conductive hydrogels are promising for flexible electronic device applications, where strain change is converted to electrical signal responses. However, most reported conductive hydrogels are typically frozen around 0°C and dried out limiting their potential applications. Herein, a highly stretchable ionic conductive hydrogel (ICH) with antifreezing and water retention properties was prepared using a natural polymer-based hydrogel (sodium alginate-co-polyacrylamide) as the matrix material. By introducing highly hydrated salt CaCl 2 and ethylene glycol via a solvent displacement method, the ICH exhibits high ionic conductivity (0.91S/m at 20°C), high transparency (95%), and antifreezing properties (−43°C). Moreover, the optimized ICH achieves a satisfactory sensitivity toward tension strain (gauge factor = 2.58 at 100% strain). Interestingly, a real-time sensing system for wearable motion based on the resulting ICH is well developed by integrating a wireless transmission platform. It is anticipated that such an ICH sensing system will significantly broaden the opportunities for flexible sensor applications.

Chronic wound healing is often compromised by bacterial infection, and wound pH changes strongly correlate with infection. Therefore, the development of wound dressings capable of real-time pH monitoring, antimicrobial activity, and tissue repair is crucial for the effective management of infected chronic wounds. This study reports a novel multifunctional composite hydrogel (GM-C-mBG@P) synthesized by incorporating microwave-synthesized carbon quantum dots (CQDs) and polydopamine-modified mesoporous bioactive glass nanoparticles (mBG@P) into modified gelatin methacryloyl (GelMA). The incorporated polydopamine (PDA) confers excellent photothermal properties to the hydrogel, enabling effective antimicrobial activity. Under 360 nm UV excitation, the fluorescence intensity of CQDs in GM-C-mBG@P exhibits a strong linear correlation with pH, enabling real-time wound pH monitoring. Furthermore, mBG@P can gradually dissolve calcium, silicon, boron, and other functional ions to enhance the bioactivity and functionality of the hydrogel and accelerate wound healing. These findings suggest that the GM-C-mBG@P hydrogel has the potential to serve as a promising wound dressing for the treatment of infected chronic wounds.

The application prospects of magnetic nanocomposites in cancer treatment and diagnosis are extensive, as they enable targeted drug delivery to tumors. Herein, a novel therapeutic strategy was proposed for oral squamous cell carcinoma (OSCC), in which polyethylene glycol-folic acid (FA-PEG) was modified on nanocomposites by combining Fe 3 O 4 and layered double hydroxide (LDH) to obtain a drug carrier for the targeted delivery of the anticancer drug berberine (Ber). We have confirmed that FA-PEG/Fe 3 O 4 @LDH exhibited a high drug loading capacity for Ber and excellent biocompatibility. Moreover, it demonstrated remarkable pH-responsive drug release (Ber release of 3.87% and 53.77% within 48 h at pH 7.4 and 5.0, respectively). The cellular experiments demonstrated that FA-PEG/Fe 3 O 4 @LDH@Ber exhibited significant inhibition of cellular activity, while the targeted release of Ber effectively depleted the overexpressed GSH and promoted ROS generation, thereby facilitating oxidative stress and inducing mitochondrial dysfunction in CAL27 cells, thus promoting apoptosis of CAL27 cells. Therefore, FA-PEG/Fe 3 O 4 @LDH can be used as a potential pH-controlled release drug delivery system which has great significance for the targeted therapy of OSCC.

Biomass-based long carbon-chain polyamide elastomers (LCPAEs) have attracted widespread attention due to their favorable physical and mechanical properties, excellent flexibility, and good heat resistance, and so on. However, the precise structure and molecular weight control of long carbon-chain polyamide (LCPA) hard segments remains underexplored, yet is pivotal for fabricating high-performance LCAPEs. Herein, the effects of temperature and time on the polymerization of dicarboxylic-terminated polyamide 1010 prepolymer (PA1010dC) are detailedly studied by end-group titration technique, and the reaction kinetic equation of PA1010dC prepolymerization stage is established. By optimizing the polymerization process based on kinetic parameters, different PA1010dC with ideal chemical structures and molecular weights (ca. 500 ~ 2700 g·mol −1 ) is obtained. Subsequently, a series of LCPAEs with various wholly-biobased hard segment (PA1010dC) contents are successfully prepared via polycondensation reaction with polytetramethylene ether glycol (PTMG) soft segments. The resulting LCPAEs show excellent comprehensive properties that can be tuned orientationally by varying the relative content of hard and soft segments. Their Shore hardness, tensile strength, and elongation at break can be varied within 20–55 D, 13–45 MPa, and 340%–1080%, respectively. This work provides a facile method for the efficient and stable preparation of LCPA hard segments and corresponding biomass LCPAEs.

With the advancement of the global dual-carbon goal, green technology has become a priority in the energy field. Among energy storage technologies, all-solid-state batteries attract significant attention due to their high energy density, enhanced safety, and long cycle life. Poly(ethylene oxide) (PEO)-based polymer solid-state electrolytes are a research hotspot for next-generation lithium-metal batteries because of their flexibility, film-forming capabilities, and compatibility with lithium salts. In this study, cyclodextrin (β-CD) is employed as a green filler and combined with high-modulus polyacrylonitrile (PAN) fibers and plastic crystalline succinonitrile (SN) to synergistically enhance the electrochemical and mechanical properties of PEO-based electrolytes. The PAN/PEO/LiClO 4 /β-CD/SN electrolyte achieves an ionic conductivity of 6.5 × 10 −5 S cm −1 at 30°C and a lithium ion transference number of 0.33 at 80°C. PAN fiber significantly improves mechanical properties, achieving a tensile strength exceeding eight times that of the PEO/LiClO 4 membrane. In Li/Li symmetric batteries, the electrolyte demonstrates excellent interfacial stability for over 1100 h at 0.1 mA cm −2 . Additionally, the LiFePO 4 |PAN/PEO/LiClO 4 /β-CD/SN|Li coin cell exhibits an initial discharge specific capacity of 148 mAh g −1 at 80°C and 0.5C, retaining 70% capacity after 200 cycles. This study presents a novel design approach for utilizing green fillers in SPEs.
