Conventional drug delivery systems often face challenges such as low biocompatibility, and limited effectiveness; thus, developing sustainable, pH-responsive materials like carboxylated cellulose nanofibrils (CNF) can enhance drug delivery efficacy. In this study, carboxylated CNF was used as raw materials, acrylic acid (AA) was used as a pH-responsive monomer, and a pH-responsive CNF composite aerogel was constructed as a drug carrier using free radical polymerization and physical blending. The microstructure and physicochemical properties of the CNF composite aerogels before and after drug loading were analyzed using advanced technologies including Fourier-transform infrared (FTIR), thermogravimetric analysis (TGA), x-ray diffraction (XRD), elemental analysis, scanning electron microscopy (SEM), and pore size analysis. The introduction of graphene oxide (GO) modified and optimized the network structure of cellulose aerogels and increased the drug-loading capacity. The network structure formed by AA polymerization made the network structure of the CNF composite aerogel more compact and uniform and prolonged the drug-release time. The loading capacities of the CNF-GO-5-FU, CNF-AA-5-FU, and CNF-AA-GO-5-FU CNF composite aerogels for fluorouracil were 286.78, 275.35, and 312.64 mg/g, respectively. The release curve of the CNF composite aerogel demonstrated a pH response that conformed to the first-order kinetics, Higuchi, and Korsmyer–Peppas models. The sustained-release mechanism of the CNF composite aerogel followed the Fickian diffusion mechanism, highlighting the aerogel's strong biomedical application potential.

The synthesis of MXenes with high surface area and porosity remains challenging due to reliance on aggressive etchants and delamination step. This work reports a mild and straightforward strategy to synthesize Ti 3 C 2 and Ti 2 C MXenes using a nano-platelet MAX phase precursor prepared via anisotropic molten salt synthesis. This precursor’s unique architecture—featuring a 15× higher surface area and 5× greater pore volume than conventional MAX phases—enables efficient Al removal with dilute hydrofluoric acid (4% HF), eliminating the need for delamination agents or post-etching processing. These MXenes achieve a high specific surface area of 105m 2/g and pore volume of 0.11c m3/g, representing 5- and 3-fold improvements over conventional MXenes. Notably, this work demonstrates the first investigation of MAX phase photothermal properties and establishes a new synthesis paradigm that eliminates delamination requirements while achieving record photothermal conversion efficiency (71.4% for MXene, 63.1% for MAX). The pre-engineered nanoplatelet architecture inherently prevents restacking, enabling stable performance for over 200 days without intercalation agents—addressing a critical limitation in MXene shelf-life and practical applicability.

Conventional techniques such as screen printing and hand-brushing, though scalable, often compromise on patterning resolution and material waste. In contrast, advanced inkjet printing offers a promising route for high-resolution and efficient manufacturing. In this study, a flexible electrode based on Ni-MOF material used high-precision scalable inkjet printing was developed for glucose sensing in human body fluids for wearable devices. Initially, Ni-MOF material with a high specific surface area and porous structure was synthesized via a hydrothermal method, and its potential for electrochemical detection was investigated. Experimental results demonstrated that the material exhibited high sensitivity and a broad detection range for glucose. Importantly, graphite and carbon nanotubes were incorporated to construct a Ni-MOF composite material with the composition ratio optimized to enhance conductivity and mechanical stability, for further application in flexible electrodes. Typically, a cost-effective, high-efficiency, and scalable fabrication process was achieved through high-precision inkjet printing technology, which enables 1200 dpi resolution while supporting ultra-large-scale printing up to 1200 × 1200 mm. Simutaneously, simulation-based optimization was conducted to determine the most effective electrode shape. As a result, the detection range of the inkjet-printed flexible electrode was extended to 0.005–2.63 mM, with an improved sensitivity of 12.2 μA·μM −1 ·cm −2 . Moreover, excellent mechanical stability and long-term durability were achieved, enabling precise differentiation of glucose fluctuations in low-concentration simulated sweat. Finally, a microfluidic channel to provide environment for the reaction was designed, thereby establishing a fundamental foundation for applying the flexible electrode in wearable devices.

To address the issues of capacity decay and poor rate performance of Bi 2 S 3 anode materials, which are caused by their intrinsically low conductivity and significant volume expansion during cycling, this study adopts a redox self-assembly strategy. Under mild hydrothermal conditions, oxygen-containing functional groups on the surface of graphene oxide (GO) induce the directed growth of Bi 2 S 3 along the [001] crystallographic direction, successfully constructing a Bi 2 S 3 /GO composite anode with strong interfacial coupling. This structure effectively suppresses the agglomeration of Bi 2 S 3 nanorods, forms a 3D conductive network, alleviates volume strain, and avoids structural damage caused by traditional high-temperature sulfidation processes. Electrochemical tests show that the 1.0-Bi 2 S 3 /GO composite retains a capacity of 300 mAh·g −1 after 100 cycles at a current density of 100 mA·g −1 . At a high rate of 5000 mA·g −1 , it still exhibits a reversible capacity of 198.62 mAh·g −1 , and after current recovery, the capacity rapidly increases to 439 mAh·g −1 , with a capacity retention rate exceeding 70%. The lithium-ion diffusion coefficient reaches 8.7×10 −1 2 cm 2 ·s −1 , which is 2.8 times higher than that of the pure phase. Mechanistic analysis reveals that the characteristic peak (τ = 0.3 s) in the distribution relaxation time (DRT) relaxation spectrum corresponds to the pseudocapacitive behavior on the GO surface, with a contribution rate of 58% at a scan rate of 2 mV·s −1 , significantly optimizing the ion storage dynamics at the interface. Additionally, the built-in electric field at the interface facilitates charge transfer, effectively shortening the relaxation time. The synergistic π-π stacking buffering network further enhances structural stability and reaction reversibility. This study, through the “directed growth-pseudocapacitance regulation-relaxation matching” triple mechanism, provides new insights for the design of high-performance sulfide-based anodes. Graphical

This paper introduces a novel electrolyte additive, 3,5-bis(trifluoromethyl)phenyl isocyanate (3,5-Bis(CF 3 )PhNCO), designed to mitigate interfacial instability and structural degradation of single-crystal LiNi 0.92 Co 0.06 Mn 0.02 O 2 cathodes under 4.6 V high-voltage cycling. Distinct from conventional monofunctional additives, 3,5-Bis(CF 3 )PhNCO integrates strongly reactive -NCO groups and electronegative -CF 3 groups, enabling a unique synergistic working mechanism. The -NCO moiety scavenges moisture and neutralizes acidic species (e.g., HF) to suppress electrolyte hydrolysis, while the -CF 3 groups enhance hydrophobicity and induce preferential oxidative decomposition for the formation of a robust cathode-electrolyte interphase (CEI). Driven by this synergistic effect, the additive constructs a ∼20 nm nitrogen-rich CEI layer, which effectively alleviates uneven Li + deposition, stabilizes the valence states of transition metals, and inhibits microcracking of the NCM92 cathode-effects validated by focused ion beam (FIB) 3D reconstruction, X-ray absorption fine structure spectroscopy (XAFS), and COMSOL Multiphysics simulations. Electrochemically, with 2 wt.% additive incorporation, the cells achieved an excellent capacity retention of 87.08% after 150 cycles at a 0.5 C rate, while full cells maintained 86.67% of their capacity after 1400 cycles at 1 C. This work establishes theoretical and experimental frameworks for multifunctional additive design, offering critical guidance for developing high-energy-density, long-life lithium-ion battery cathodes.

Intercalation-based exfoliation offers a cost-effective approach to producing 2D materials. While molecular intercalation surpasses ionic methods in preserving the crystallinity and intrinsic properties of 2D materials, its broader adoption is limited by weak driving forces and slow kinetics. To address these challenges, we propose an interlayer modulation strategy using H 3 PO 4 -amine complexes as mediators. Structural and molecular dynamics analyses demonstrate that these complexes regulate interlayer proton activity through strong hydrogen bonding, thereby optimizing interlayer dynamics to enable in situ PW 12 formation and efficient graphite exfoliation. The PW 12 intercalant shows excellent recyclability via simple alkaline hydrolysis and regeneration, establishing a sustainable route for graphene production. This work overcomes the barrier to molecular intercalation by rationally engineering complex molecular intercalation, achieving universal and high-throughput exfoliation of van der Waals layered materials.

Given that ochratoxin A (OTA) exhibits immunotoxic, teratogenic, and carcinogenic properties, it is essential to monitor its presence in food samples. In the present work, a novel electrochemical aptasensor for OTA detection uses β-cyclodextrin-functionalized graphene (CG) to enhance electron transfer and provide abundant double-stranded DNA (dsDNA) binding sites. The sensor immobilizes OTA aptamers, complementary DNA (cDNA), and ferrocene-labeled dsDNA on a gold nanoparticle-modified electrode. The host–guest interaction between β-cyclodextrin (β-CD) and ferrocene (Fc) stabilizes the sensing layer, while thiolated dsDNA ensures strong attachment to AuNPs. Without OTA, impedance is high and current is low. In the presence of OTA, its high affinity for the aptamer induces conformational changes in dsDNA. Upon applying an oxidative potential, ferrocene is oxidized to Fc+, which, due to reduced hydrophobicity, dissociates from β-CD. This releases dsDNA from the electrode surface, reducing the impedance and enhancing the current response. The sensor demonstrates a robust response across a concentration range of 1 pg mL−1 to 100 ng mL−1, achieving a detection limit of 0.78 pg mL−1. Notably, this method has been successfully applied to detect OTA in wine, yielding high recovery rates of 96.20% to 98.67%. These findings suggest that the MCH/AuNPs/dsDNA/CG/GCE configuration is a promising electrochemical sensor for OTA detection.

This study presents a novel slit evaporation self-assembly method for fabricating freestanding sulfuric acid-treated reduced graphene oxide/commercial graphene films (S-ATrGO/CG). The unique capillary slit-induced self-assembly process facilitates the alignment and stacking of graphene flakes, resulting in a well-ordered, laminated film. The treatment of graphene oxide (GO) with sulfuric acid facilitates the ring-opening of inert functional groups, converting them into active functional groups. Sulfuric acid-treated graphene oxide (ATGO) can serve as an effective binder for adhering commercial graphene flakes. X-ray photoelectron spectroscopy was used to quantitatively analyze the oxygen-containing functional groups in GO, ATGO, and S-ATrGO/CG. A series of electrochemical tests were conducted to investigate the behavior of the S-ATrGO/CG films, which exhibited well-defined redox peaks, indicating the contribution of unreduced oxygen-containing groups to redox reactions and pseudocapacitance. The S-ATrGO/CG films exhibit superior electrochemical performance, with an ultra-high area-specific capacitance of 1,589.78 mF cm-2 at a scan of 5 mV s-1 and an impressive initial capacitance retention of 99.80% after 20,000 cycles at a current density of 50 mA cm-2. This study highlights the potential of S-ATrGO/CG films as high-performance electrodes for supercapacitors, contributing to the advancement of sustainable energy storage systems.

Electric-field-sensitive dielectrics play a crucial role in electric field induction sensing and related capacitive conversion, with interfacial polarization and charge accumulation largely determining the signal output. This paper introduces graphene/transition metal dichalcogenide (TMD) (MoSe 2 , MoS 2 , and WS 2 ) heterojunctions as functional fillers to enhance the dielectric response and electric-field-induced voltage output of flexible polydimethylsiloxane (PDMS) composites. Density functional theory (DFT) calculations were used to evaluate the stability of the heterojunctions and interfacial electronic modulation, including binding behavior, charge redistribution, and Fermi level-referenced band structure/total density of states (TDOS) characteristics. The calculations show that the graphene/TMD interface is primarily controlled by van der Waals forces, exhibiting negative binding energy and significant interfacial charge rearrangement. Based on these theoretical results, graphene/TMD heterojunction powders were synthesized and incorporated into polydimethylsiloxane (PDMS). Structural characterization confirmed the presence of face-to-face interfacial contacts and consistent elemental co-localization within the heterojunction filler. Dielectric spectroscopy analysis revealed an overall improvement in the dielectric constant of the composite materials while maintaining a stable loss trend within the studied frequency range. More importantly, calibrated electric field induction tests (based on pure PDMS) showed a significant enhancement in the voltage response of all heterojunction composite materials, with the WS 2 -G/PDMS system exhibiting the best performance, exhibiting an electric-field-induced voltage amplitude 7.607% higher than that of pure PDMS. This work establishes a microscopic-to-macroscopic correlation between interfacial electronic modulation and electric-field-sensitive dielectric properties, providing a feasible interface engineering strategy for high-performance flexible dielectric sensing materials.

In this study, a photorechargeable supercapacitor was prepared with ZnMoO4, Zn(CF3SO3)2 and reduced graphene oxide hydrogel (rGH) as the photoanode, electrolyte and cathode, respectively. The microstructure, phase composition, light absorbance, specific surface area and chemical structure of products and the photoelectrochemical performance of supercapacitors were characterized using field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), high-resolution transmission electron microscopy (HR-TEM), ultraviolet-visible (UV-vis) spectroscopy, Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS), Raman spectroscopy, and electrochemical workstation. The ZnMoO4//rGH supercapacitor exhibited a high specific capacity of 156.09 F g−1 under photoelectric synergistic charging (namely, a light intensity of 95 mW cm−2 and a current density of 0.5 A g−1), which increased by 35.66% relative to that of only electric charging. Meanwhile, the capacity retention and coulombic efficiency rates of the device are 137% and 100%, respectively, under photoelectric synergistic charging and discharging for 10 000 cycles. This suggests that the ZnMoO4//rGH photorechargeable supercapacitor exhibits excellent stability and shows applications in the wearable electronic industry.

Rechargeable aqueous Zn||MnO 2 batteries using near-neutral electrolytes have attracted considerable interest owing to their environmental benignity and high safety. However, MnO 2 cathodes with high mass loading suffer from sluggish reaction kinetics and structural degradation during long-term cycling, particularly under low-current-density conditions. Limited ion diffusion in thick electrodes results in capacity fading, while slow proton intercalation aggravates irreversible phase transitions, leading to active material dissolution and rapid capacity loss. To address these challenges, we propose a dual-modification strategy involving Ce doping and reduced graphene oxide (rGO) coating. The charge compensation effect induced by Ce doping increases the Mn 3+ /Mn 4+ ratio in MnO 2 from 0.36 to 0.61, effectively optimizing the electronic structure and improving lattice stability. Meanwhile, the constructed three-dimensional rGO conductive network reduces interfacial charge-transfer resistance and alleviates volume strain during cycling. Benefiting from this synergistic effect, the composite cathode achieves an areal capacity of 2.05 mAh cm −2 at 0.1C and retains 77.8 % of its initial capacity over 507 cycles at 2 C. This work offers a novel synergistic strategy for designing high-mass-loading cathodes and advances the practical implementation of Zn||MnO 2 batteries in grid-scale energy storage.

This study developed a S-doped two-dimensional molybdenum carbide composited with graphene oxide (S-Mo x C/GO) for efficient electrochemical degradation of methyl orange (MO). The incorporation of S refined the MoₓC nanocrystals and reduced graphene stacking, significantly enhancing electrocatalytic performance. The S- Mo x C /GO system achieved 99.9% removal of 10 mg/L MO within 45 min, outperforming the undoped counterpart (95.2%). Quenching tests identified singlet oxygen ( 1 O 2 ) as the dominant reactive species. DFT calculations revealed that S doping facilitates H 2 O adsorption and promotes electron transfer from H 2 O to adjacent Mo sites, thereby accelerating the activation of oxygen species for 1 O 2 generation. Degradation pathways were proposed based on HPLC and computational analysis. Additionally, toxicological assessment indicated that most degradation products exhibit low ecological risk. This work elucidates the role of S doping in enhancing catalytic activity and provides a feasible strategy for designing efficient Mo x C-based catalysts for organic wastewater treatment.
