Phenolic impregnated carbon ablator (PICA) is a lightweight ablative material extensively used in thermal protection systems. However, its performance is limited by the poor oxidation resistance of carbon fibers and the insufficient thermal stability of the phenolic matrix at elevated temperatures. To address these challenges, a Si–Zr binary-modified carbon fiber-reinforced phenolic aerogel composite (denoted as S a Z b -CF/PA) was fabricated via a two-step sol–gel process. A SiO 2 –ZrO 2 ceramic coating was formed in situ on the fiber surface, serving as an effective barrier against oxygen diffusion. The resulting composite exhibits a low density (∼0.70 g/cm 3 ), high compressive strength, and excellent oxidation and ablation resistance. After exposure to air at 1000 °C, S a Z b -CF/PA retained 47.5 wt% of its mass, whereas the unmodified composite retained only 2 wt%. Under oxyacetylene flame testing (2 MW/m 2 for 60 s), the composite demonstrated low linear and mass ablation rates of 0.0160 mm/s and 0.0048 g/s, respectively. Microstructural analysis revealed the formation of a dense and continuous SiO 2 –ZrO 2 -rich ceramic layer that effectively protects the underlying structure during ablation. These results indicate that fiber-level ceramic modification via sol–gel coating is a promising strategy for developing high-performance lightweight ablative composites for extreme thermal environments.

With the fast development of precision medicine, porphyrin-based photosensitizers (PSs) have been extensively employed in photodynamic therapy (PDT). However, their poor water solubility and aggregation-induced self-quenching during reactive oxygen species (ROS) generation result in less satisfactory therapeutic outcomes. Herein, three novel porphyrin derivatives have been successfully synthesized through adjusting the ratios of hydrophilic and hydrophobic side chains, and ultimately three different sizes of carrier-free porphyrin nanoparticles (NPs) have been prepared by nanoprecipitation. The three porphyrin NPs exhibited good water dispersion, stable photophysical properties, and showed a higher efficiency in singlet oxygen (1O2) generation than traditional porphyrin-based PSs under 660 nm laser irradiation. Among them, T2 NPs exhibit the highest phototoxicity during in vitro cell experiments, attributed to their effective cellular uptake, high intracellular ROS yields, and specific localization in the mitochondria and lysosomes of T2 NPs in tumor cells. Moreover, in vivo animal experiments further confirmed the outstanding antitumor activity of T2 NPs under PDT treatment, along with excellent biocompatibility and biosafety. This study provides a promising strategy for utilizing modified water-soluble porphyrin NPs as highly effective PSs, demonstrating great potential in enhancing PDT efficacy.

The rapid growth of flexible Internet of Things devices and multisensory human-computer interaction necessitates advanced systems capable of multimodal data sensing, processing, and feedback in an intelligent and energy-efficient manner. However, conventional architectures face limitations in energy inefficiency and interface mismatch due to the fragmented architecture of sensing, processing, and feedback units. Inspired by biological sensory systems, we introduce an MXene-based flexible dual-mode sensing-processing-visualizing integrated system into a single wearable device through a hierarchical MXene platform combining piezoelectric nanogenerators (mechanosensation), optoelectronic synapses (visual processing), and color-shifting quantum dot light-emitting diodes (optical feedback) with optimized interfaces. The wearable integrated system demonstrates tactile-visual signal recognition capabilities, biological self-protection behavior to adapt to environmental stimuli, dynamic trajectory recognition, and spatial positioning for motion recognition, which are highly desired in multisensory interaction. The bio-inspired material-architecture-function co-design strategy and integrated system promote the development of wearable neuromorphic hardware, edge computing, and intelligent human-machine interaction.

To overcome the limitations of conventional ionic liquid-based CO 2 absorbents—namely high regeneration energy consumption and low absorption capacity—a novel biphasic dual-functionalized ionic liquid system, [AEPH][Im]/NPA/H 2 O, was synthesized and evaluated. Initially homogeneous, the system undergoes spontaneous phase separation upon CO 2 absorption, forming distinct lean and rich phases. At saturation, the rich phase accounted for 53.00% of the total volume, with a viscosity of 15.75 mPa·s and a CO 2 loading capacity of 3.43 mol·L −1 . The system exhibited a high regeneration efficiency of 83.42% at 393.15 K, and the regenerated phases could be recombined into a uniform solution. After six absorption-desorption cycles, the absorbent retained 96.39% of its initial capacity, with only a 1.32% decline in desorption efficiency. The 13 C NMR analysis and DFT calculations revealed that CO 2 primarily reacts with [AEPH][Im] to form carbamate, carbonate, and bicarbonate species, which are predominantly concentrated in the rich phase, while only unreacted components remain in the lean phase. NPA facilitates the formation of alkyl carbonates via reaction with carbamates, and the high concentration of bicarbonate significantly enhanced desorption efficiency. The total regeneration energy consumption was calculated to be as low as 1.58 GJ·t −1 CO 2 —markedly lower than that of traditional MEA-based solvents. The [AEPH][Im]/NPA/H 2 O biphasic system demonstrates superior cyclic stability, high CO 2 capture capacity, and low energy demand, presenting a promising alternative for industrial-scale carbon capture applications.

Poly(3,4-ethylenedioxythiophene) (PEDOT) has become a key electrode material for supercapacitors due to its high conductivity, stability, and flexibility. Its charge storage is associated with redox reactions, and oxidation doping is a critical factor to determine the redox reaction. However, the mechanism by which oxidation doping affects PEDOT's capacitive performance lacks a thorough systematic explanation. This study controlled the oxidation doping characteristics of PEDOT by introducing chloromethyl (-MeCl) and hydroxymethyl (-MeOH) groups for surface modification. For the first time, the combination of density functional theory and experiment proves that the oxidative doping level of PEDOT is determined by both oxidation and doping processes. The electron-withdrawing effect of -MeCl lowers the highest occupied molecular orbital (HOMO) energy level of PEDOT and reduces the electron density on its conjugated backbone, making it more difficult to be oxidized. Conversely, the electron-donating effect of -MeOH promotes the oxidation of PEDOT. The steric hindrance effect of the side chain increases the interlayer spacing of PEDOT's molecular chains, hindering its doping. Under the combined effects of oxidation and doping, the oxidation doping level and carrier concentration of PEDOT decrease obviously after introducing -MeCl, while the decrease was not obvious after the introduction of -MeOH. The introduction of side groups, particularly -MeCl, significantly increases the interlayer spacing and π-π stacking distance of PEDOT, leading to a significant decrease in carrier mobility. Although increasing the interlayer spacing of PEDOT hinders its doping, it simultaneously exposes more active sites. Therefore, the redox reaction can be fully carried out at low current density, which obviously improves the capacitance of PEDOT. As the current density increases, the capacitance of PEDOT decreases most rapidly after the introduction of -MeCl. This is because the lowest carrier mobility hinders the redox reaction. -MeCl increases the oxidation potential of PEDOT, thereby enhancing its cycling stability, with a capacitance retention exceeding 99% after 2000 cycles. The introduction of -MeOH, which exhibits lower steric hindrance, exposed more active sites without significantly reducing the oxidation doping level and carrier mobility of PEDOT. Consequently, it significantly boosts the capacitance and energy density of PEDOT without noticeable degradation in cycling stability, delivering the best overall performance. This study systematically reveals for the first time the mechanism by which oxidative doping affects the capacitive properties of PEDOT. It is proved that surface modification of PEDOT is an effective method to improve its capacitance performance. This has important theoretical value for promoting the performance breakthrough of conductive polymer electrode materials.

This study investigated the impact of rice bran protein (RBP) fibril polymers (PFs) on the properties of mayonnaise-like emulsions. Using RBP with different structures during PFs formation, plant-based emulsions were prepared and evaluated for interfacial protein adsorption (AP%), water-holding capacity (WHC), rheological and textural properties, color, sensory quality, and storage stability. PFs–based emulsions had 11.29% and 16.8% higher AP% values and 43.73% and 107.64% higher WHC values than those of RBP emulsions and homemade mayonnaise, respectively. Texture analysis showed significant improvements in hardness, viscosity, cohesiveness, and springiness. After 30 days, peroxide values in PFs-emulsions were 25.13% lower than those in RBP emulsions and 33.57% lower than homemade mayonnaise; malondialdehyde content was 15.57% and 21.25% lower, respectively. The total viable count of PF aggregate emulsions was 21.51% lower than that of RBP emulsions. These findings highlight the enhanced stability of PFs–based mayonnaise-like emulsions.

Triethylamine (TEA), a hazardous industrial volatile organic compound, requires sensors with rapid response and ppb-level sensitivity. This study synthesized m-LaVO 4 nanospheres with controlled exposed crystal facets via a hydrothermal method. The optimized material, featuring a layered morphology and dominant (200) plane, showed a high response of 27.2 to 100 ppm TEA at 225°C with a 5 s response time, shortening to 2 s at 15 ppm. The sensor demonstrated a low detection limit of 1 ppb, excellent selectivity, repeatability, long-term stability, and light-modulated sensing behavior. These properties are attributed to the unique layered structure and surface characteristics of m-LaVO 4 , making it a promising candidate for efficient, low-concentration TEA detection.

Efficient extraction and sensitive determination of neonicotinoid insecticides in intricate matrix remain a challenge due to their high-water solubility and trace level. Herein, an irreversible 4-carboxyl-quinoline linked COF, named CQ-COF TAPB-DHTA/DMTA , was synthesized via a one-pot multicomponent Doebner reaction. The CQ-COF TAPB-DHTA/DMTA incorporated abundant bifunctional hydroxyl and carboxyl groups while exhibiting enhanced hydrophilicity and excellent chemical stability. Then, solid-phase microextraction (SPME) fiber based on CQ-COF TAPB-DHTA/DMTA was prepared and exhibited exceptional durability and remarkable extraction performance for eight neonicotinoids. After coupling with ultra-high performance liquid chromatography tandem mass spectrometry (UPLC-MS/MS), an ultrasensitive analytical method was developed with low limits of detection (0.51–3.5 ng L −1 ), wide linear range, and satisfactory correlation coefficients (R 2 ≥ 0.9910), and was successfully used for analysis of neonicotinoids in water and honey samples. This work highlights the potential of multifunctional and stable COFs for the extraction and analysis of polar pollutants from intricate matrices.

Photothermal (PT) synergistic catalysis for the conversion of CO 2 to methanol (MeOH) represents a promising strategy for CO 2 utilization. However, the development of Cu-ZnO catalysts exhibiting high thermal stability and photocatalytic activity remains a critical challenge for efficient CO 2 conversion via the PT catalysis. To address these issues, Pd single atoms are successfully anchored onto the Cu-ZnO surface of the Z -scheme heterostructure (designated as Pd 1 /Cu-ZnO), resulting in three distinct asymmetric coordination environments: Pd-O-Cu, Pd-Cu, and Pd-O-Zn. The non-uniform charge distribution at the Pd-Cu site on Pd 1 /Cu-ZnO enhances the adsorption and dissociation of H 2 , while the Pd-O-Zn site simultaneously optimizes the CO 2 adsorption configuration, thereby promoting significant elongation of the C=O bond. The band structures of semiconductors (CuO and ZnO) are modulated by Pd single atoms, which simultaneously enhances the localized surface plasmon resonance (LSPR) effect for Cu 0 , thereby improving Pd 1 /Cu-ZnO light response. The MeOH yield achieved with Pd 1 /Cu-ZnO as the catalyst is 1.45 times greater in the PT catalytic reaction compared to the thermal catalytic reaction, reaching 332.1 mmol·g −1 Cu·h −1 , while the selectivity increased from 50.1% to 87.2%, highlighting the exceptional performance of the single atom asymmetric sites. This study underscores the crucial role of single atoms in PT synergistic catalysis, demonstrating their superior potential for enhancing CO 2 utilization under mild conditions and improving atomic economy.

The aggregation of TiO 2 precursors affects the structural evolution and catalytic performance of sulfated titania, highlighting a relationship between microscale and macroscale reactivity. In the present work, the sulfated titania (TiO 2 /SO 4 2− ) solid acid catalysts were synthesized through the impregnation approach using two different precursors, pre-aggregated TiO 2 (microscale) and molecular-scale Ti(OH) 4 . The catalysts were characterized using X-ray diffraction, Fourier transform infrared spectroscopy, Brunauer-Emmett-Teller analysis, and ammonia temperature-programmed desorption (NH 3 -TPD). Their catalytic activity was tested in the transesterification reaction of ethyl acetate with n-butanol. The TiO 2 /SO 4 2− derived from Ti(OH) 4 precursor exhibited a single-phase anatase structure with (92%) higher specific surface area (63.85 m 2 g − 1 vs. 33.38 m 2 g − 1 ), smaller crystallite size (8.05 nm), and higher catalytic conversion (70%) as compared to the catalyst prepared from pre-aggregated TiO 2 . These differences are attributed to variations in precursor aggregation, which influence crystallite growth, sulfate dispersion, and surface area acidity, thereby enhancing catalytic performance during transesterification. The present work establishes a link between TiO 2 precursor aggregation and the catalytic activity of TiO 2 /SO 4 2− . The results demonstrate that the aggregation state of the TiO 2 precursor inherently governs the physicochemical characteristics and catalytic behavior of sulfated titania, providing a rational basis for tailoring solid acid catalysts for esterification and transesterification reactions.

Effective intra-articular therapy requires injectable depots that persist in the synovial space and modulate local inflammatory and oxidative microenvironments. Here, we developed a high-aspect-ratio short-fiber platform based on acid-labile acetalated dextran (AcDEX) for sustained intra-articular drug delivery. Continuous AcDEX fibermats electrospun from low-molecular-weight (10 kDa) dextran self-disintegrated within seconds into injectable short fibers (average aspect ratio ~ 30) upon mild agitation in aqueous media, enabling on-demand preparation without post-processing. Resveratrol (RES), a hydrophobic antioxidant and anti-inflammatory compound, was encapsulated into AcDEX by blend electrospinning. RES@AcDEX fibers remained chemically intact during disintegration and provided sustained, pH-accelerated RES release (pH 6.8 vs 7.4) together with prolonged intra-articular retention, as evidenced by joint-confined fluorescence detectable for up to 10 days after injection. Released RES scavenged reactive oxygen species (ROS) in a dose-dependent manner, reduced intracellular ROS in lipopolysaccharide (LPS)-stimulated macrophages, and modulated inflammatory macrophage phenotypes in vitro. In a gouty arthritis model, a single intra-articular injection of RES@AcDEX short fibers reduced swelling, improved gait performance, downregulated proinflammatory cytokines, and upregulated anti-inflammatory cytokines in periarticular tissues. Overall, self-disintegrating AcDEX short fibers offer a simple and tunable, shape-engineered intra-articular depot for local modulation of ROS and inflammation, with potential utility for gouty arthritis and other inflammatory joint disorders.
