High-value utilization of agricultural waste • Green and low-cost fabrication • Synergistic double-layer design • Efficient solar desalination performance • Practical applicability Sorghum distillers' grains (SDG) are abundant by-product of sorghum liquor production but are often underutilized. In this study, we report a form-stable, carbohydrate-based double-layer aerogel (DLA) fabricated via directional freezing followed by ambient-pressure drying, which avoids energy-intensive supercritical freeze-drying routes. Cellulose nanofibers (CNF) extracted from SDG via TEMPO-mediated oxidation were combined with sodium alginate to form a Ca 2+ -crosslinked skeleton, and an rGO/g-C 3 N 4 photothermal layer was integrated on top to construct the DLA evaporator. By tuning the rGO/g-C 3 N 4 ratio, A 3 (0.6/0.4, w /w) exhibited markedly enhanced dimensional stability during cycling, showing only 3.2% projected-area shrinkage after 10 days, compared with severe shrinkage in the control samples. Meanwhile, A 3 maintained efficient solar evaporation with an evaporation rate of 1.43 kg·m −2 ·h −1 and a photothermal conversion efficiency of 93.14% under simulated irradiation. Outdoor tests further confirmed robust freshwater production across seasons (maximum 2.74 kg·m −2 ·h −1 ), and the collected condensate satisfied WHO ion-concentration guidelines. This work demonstrates an ambient-pressure-drying-enabled, form-stable CNF aerogel platform for scalable solar desalination and SDG valorization.

In recent years, with the development of electric vehicles and electric vessels, the issues of battery thermal safety have garnered significant attention. Composite phase-change materials (CPCMs) hold great potential as passive cooling systems in battery thermal management systems (BTMS), but their high flammability remains an unresolved challenge. This study successfully developed a flexible composite phase-change material, CPCM/P-CSF@rGO, by encapsulating a eutectic phase-change material composed of mannitol and galactitol in a three-dimensional hydrogen-bonded network, self-polymerised by phosphated corn straw cellulose (P-CSF) and reduced graphene oxide (rGO). The study demonstrates that the strong hydrogen bonding network formed between the phosphate groups introduced by phosphoric acid modification and rGO constructs highly efficient thermal conduction pathways, achieving a thermal conductivity of 1.039 W/(m•K) and significantly accelerating thermal response rates. Simultaneously, the incorporation of the P-CSF@rGO framework endows the material with excellent flexibility and shape stability. Due to the in-situ flame-retardant modification of the framework, the phase-change material maintains a high latent heat of phase-change (194.7 J/g) and achieves superior flame retardancy through gas-phase and condensation-phase mechanisms. It exhibits a limiting oxygen index of up to 30.64% and rapidly extinguishes itself when exposed to open flame in atmospheric conditions. Thus, the flexible composite phase-change material (CPCM/P-CSF@rGO) supported by a phosphorylated cellulose framework emerges as a promising candidate for ensuring safety and high performance in thermal management applications.

Phase change materials (PCMs) show great promise for thermal management and solar energy harvesting, but their practical applications are hindered by liquid leakage, low thermal conductivity and weak optical absorption. Herein, we report a series of multifunctional composite PCMs engineered via a synergistic dual-encapsulation strategy. The interfacial assembly of TEMPO-oxidized cellulose nanofibrils (TOCN) and graphene oxide (GO) on the n-docosane droplet surface is achieved via the Pickering emulsion method. Subsequently, ultraviolet-assisted reduction and in situ polymerization of polypyrrole (PPy) are employed to construct a hierarchical 3D microcapsule. This robust architecture effectively improves leakage resistance, achieving a high encapsulation rate of 82.80% and exceptional cycling stability. The continuous 3D network formed by vacuum-filtered microcapsules increases the thermal conductivity to 0.435 W·m −1 ·K −1 and the electrical conductivity to 90.09 S/m. Meanwhile, the synergistic rGO/PPy network provides broadband optical absorption and high electrical conductivity, yielding photothermal and electrothermal conversion efficiencies of 91.25% and 78.86%, respectively. In practice, the composite reduces the peak temperature of a simulated CPU by 12.06 °C, and integration with a thermoelectric generator (TEG) enables simultaneous solar-thermal-electricity conversion. This work pioneers a scalable route for high-performance composite phase change materials in advanced thermal management and multi-source energy harvesting.

The advancement of wearable and human-centered electronics drives increasing demand for high-speed, reliable chemical sensors capable of detecting physiologically relevant signals. Among various target analytes, ammonia (NH 3 ) is of particular importance due to its relevance in environmental exposure assessment and noninvasive health monitoring. However existing wearable NH 3 sensors are often limited by slow response dynamics, rigid material systems, and poor tolerance to humidity and temperature variations. Herein, these challenges are addressed by integrating a disordered graphene–protein composite with a micro-gap electrode architecture. Exfoliated disordered graphene ( EG ), synthesized via a scalable solvent-assisted exfoliation process, is combined with chicken egg-derived albumen to form a conductive and biocompatible sensing layer interfaced with ∼13 µm micro-gap electrodes. Owing to the synergistic dual-sensing mechanism arising from EG and protein functional groups, the sensor exhibits fast response and recovery times of 0.7 s and 1.1 s, respectively, toward 5 ppm NH 3 at room temperature. The test gas was injected in the test chamber close to the sensor surface. Systematic investigations revealed that the NH 3 response is influenced by environmental conditions, with (absolute) resistance magnitude decreasing under elevated humidity and temperature due to enhanced adsorption and charge-transfer processes. Leveraging these attributes, real-time NH 3 detection is demonstrated under physiological temperature conditions and for urine-derived ammonia. This work establishes a sustainable and high-performance sensing strategy for next-generation wearable monitoring technologies.

Ship icing poses significant safety and operational risks. Although superhydrophobic coatings (SHCs) offer a promising passive anti-icing strategy, their practical application is limited by factors such as poor durability, the environmental constraints of single-function de-icing methods, and ecological issues associated with fluorinated materials. To address these challenges, this study has designed a novel fluorine-free multifunctional superhydrophobic coating that integrates photothermal effects and self-healing capabilities. The coating uses γ-aminopropyltriethoxysilane (KH-550) as the key modifier for the fluorine-free modification of epoxy resin; the surface layer achieves self-healing superhydrophobic functionality through the thermal mobility of beeswax, while the bottom layer consists of acetylene black and nanoscale graphite powder to form a conductive network. Leveraging its photothermal and electrothermal effects, the coating can melt accumulated ice via rapid photothermal heating (reaching approximately 90 °C within 300 s). Additionally, through heat-induced conduction of beeswax, the coating can autonomously restore its superhydrophobicity after mechanical or chemical damage and maintain performance over multiple cycles. The resulting coating exhibits strong adhesion to the substrate. After immersion in a 3.5 wt.% NaCl solution for 14 days, its corrosion current density is only 2.56 × 10 –10 A/cm 2 , representing a 99.47% improvement compared to silicon-modified epoxy resin (Si-EP). Furthermore, even under prolonged sand particle erosion, the coating retains long-lasting superhydrophobicity. This study provides a promising and scalable strategy for advanced anti-icing applications in marine environments by synergistically combining environmental friendliness, photothermal de-icing, self-healing durability, and enhanced corrosion resistance in a fluorine-free system.

In this work, a “CO 2 capture and ex situ utilization” strategy was proposed by combining calcium looping and a subsequent cycloaddition reaction. In the calcium looping step, the CaO-based sorbent was prepared from bulk industrial solid waste, i.e., carbide slag as the calcium source and blast-furnace slag as the dopant. Both wet mixing and sol-gel methods were explored in this study. Among them, the sorbent synthesized via the sol-gel route with sucrose as a complexing agent showed improved cyclic performance. This improvement is presumably attributable to the sol-gel method's ability to enhance the distribution of blast furnace slag and optimize the sorbent's pore structure. By further regulating sorbent preparation parameters such as the mass ratio of carbide slag to blast furnace slag, the sucrose amount, and the calcination temperature and time, the optimal sorbent was obtained with an initial CO 2 uptake of 0.552 g CO 2 /g sorbent at 740 o C. Furthermore, the CO 2 uptake was still retained at 92% even after 10 cycles. The CO 2 released from Ca-looping ex situ reacted with propylene oxide (PO) to afford a 91% yield of propylene carbonate catalyzed by graphene oxide (GO) and tetrabutylammonium bromide (TBAB), avoiding conventional CO 2 compression and transportation. As expected, this study represents a potential large-scale application of integrating industrial solid waste management, carbon capture, and valorization to value-added chemicals and materials.

Reductive bioremediation is widely applied to detoxify environmental contaminants in wastewater, yet its efficiency is often constrained by the limited availability of electron donors required to sustain microbial metabolism. Herein, we establish an electromagnetic induction–driven nanobiohybrid strategy for efficient reductive degradation of methyl orange (MO) without the addition of conventional chemical reductants or external solar irradiation. By integrating the electroactive bacterium Geobacter sulfurreducens PCA ( G. s ) with conductive graphite nanosheets (GNS), we constructed a nanobiohybrid system that transduced magnetic flux variations under magnetic field (MF) stimulation into bioavailable electrons, thereby creating a microbial electron supply pathway powered by magnetic energy. The G. s -GNS nanobiohybrid system maintained high MO degradation efficiency (≥ 94.9%) over three consecutive 48-h cycles under MF conditions, demonstrating robust operational stability. Mechanistic investigations revealed that electromagnetic induction significantly enhanced interfacial electron availability within the nanobiohybrid system. This enhanced electron flux, enabled by interfacial water dissociation facilitated by surface potential amplification at GNS interfaces, facilitated extracellular electron transfer and reshaped microbial carbon and energy metabolism, ultimately accelerating reductive pollutant transformation. Overall, this work establishes a physical energy–microbe coupling paradigm for regulating microbial redox processes, providing new insights into the design of energy-efficient and sustainable wastewater treatment technologies.

GO/PDA-160 is used as a photothermal filler in organic coatings. • The coating shows a water contact angle of 163.1° and sliding angle of 3.83°. • The coating suppresses icing and enables fast photothermal de-icing. • The GO/PDA-160 coating can scratch repair and restore superhydrophobic. Traditional superhydrophobic coatings are susceptible to mechanical damage and generally lack active de-icing and self-healing capabilities, which limits their long-term application in harsh environments. In this study, graphene oxide (GO) is modified with different amounts of polydopamine (PDA) to optimize its photothermal performance, and the GO/PDA-160 composite exhibits relatively high photothermal response. GO/PDA-160 is subsequently incorporated with silica, polydimethylsiloxane, and epoxy resin to fabricate a multifunctional composite coating with superhydrophobic, photothermal anti-icing/de-icing, and photoresponsive self-healing properties via a spray-coating method. The results shows that the coating containing 20 mg of GO/PDA-160 achieves a water contact angle of 163.1° and sliding angle of 3.83°, indicating favorable superhydrophobic and self-cleaning performance. The coating effectively delays ice-crystal nucleation and enables active photothermal de-icing through rapid heating under visible light irradiation. In addition, it exhibits strong resistance to water-jet impact and blade scratching. After 20 min of visible-light irradiation, surface scratches are partially repaired, and both the surface morphology and superhydrophobic properties are largely restored. These results suggest that the proposed coating provides a promising strategy for developing durable multifunctional protective coatings for harsh and complex environments.

The synthesis of phase-pure out-of-plane ordered MAX phases (o-MAX) Cr2VAlC2 and Cr2V2AlC3 is notoriously challenging and often hindered by parasitic reactions inherent to conventional elemental powder routes. This work combines thermodynamic calculations with experimental synthesis to validate the proposed solid-state reaction pathways employing Cr2AlC and VC as starting compositions to prepare high-purity o-Cr2VAlC2 and o-Cr2V2AlC3 MAX phases in the Cr–V–Al-C system. The thermodynamic formability of 312 and 413 MAX phases is evaluated by calculating the formation enthalpies and Gibbs free energies for both fully ordered o-MAX phases and their corresponding solid solutions, confirming the high thermodynamic stability of o-MAX compounds in comparison to solid solution forms from both typical elemental powder metallurgy and solid-state reaction synthesis. Combining the linear programming optimization algorithm for reaction thermodynamics and the systematic experimental verifications of phase formation kinetics, high yields of o-Cr2VAlC2 (82.0 wt %) and o-Cr2V2AlC3 (88.7 wt %) MAX phases are obtained with starting compositions as Cr2AlC/VC = 1:1.2 and 1:1.9 at the sintering temperature of 1500 °C. Using the JMAK equation, the apparent activation energies for phase nucleation and growth of o-Cr2VAlC2 and o-Cr2V2AlC3 phases are found to be 313.6 and 98.4 kJ mol–1, respectively. The calculated electronic density of states and bond orders for solid solutions and fully ordered MAX phases confirm that the stabilization of higher-order o-MAX phases in the Cr–V–Al-C system is mainly attributed to the significant reduction of Cr–C and V–C bond orders for those antisite atoms in disordered structures. This work elucidates a new pragmatic strategy to precisely tailor both reaction thermodynamics and kinetics for the synthesis of o-MAX phases in general.

Chiral nematic cellulose nanocrystal films are one-dimensional photonic crystals, which receive a lot of attention in many fields, including visible sensors and actuators, anticounterfeiting, iridescent coatings, and other photonic materials that profit from the unique optical properties. Herein, we report a dual-actuated bilayer film of cellulose nanocrystals and graphene oxide for circular polarization encryption. The bilayer structure is capable of reversible shape deformation in response to humidity and NIR irradiation, accompanied by tunable circular polarization properties. The shape deformation generates the band gap of cellulose nanocrystal layer blue shift with the increase of incident light angle, and the peak wavelength of the cellulose nanocrystal layer no longer matches the original photosource. Different patterns appear on the degree of circular polarization (DOCP) distribution map resulting from incident angle-dependent circularly polarized reflection. The cellulose nanocrystal-based bilayer film shows unique potential for circular polarization display of humidity actuators.

In the present study, an amperometric aflatoxin B1 sensor was constructed via modifying a nano-graphite carbon paste microelectrode with a cationic surfactant of cetyltrimethylammonium bromide (CTAB) and a perfluorosulfonic acid resin of Nafion through a simple and controllable electrochemical scanning method. The experiment results show that CTAB–Nafion composite film has a good catalytic effect on the electrochemical response of aflatoxin B1. The electrocatalytic mechanism was investigated with the aid of different analytical techniques, including square wave voltammetry, electrochemical impedance spectroscopy, chronocoulometry, energy-dispersive spectroscopy and scanning electron microscopy. Under the optimal conditions, the linear range of the sensor is from 0.1 nM to 100 nM, and its detection limit and sensitivity are 20 pM (S/N = 3) and (24.9 ± 1.51) μA/nM, respectively. The accurate and rapid detection of aflatoxin B1, which has strong carcinogenicity, is of great significance for food quality monitoring and the protection of human health. Therefore, finally, the sensor was used to detect the concentration of aflatoxin B1 in milk and soy sauce samples, and the favorable recovery results indicated its good application prospects.

Designing efficient and stable photocathodes remains a critical challenge for advancing high-performance photocatalytic fuel cell (PFC) systems toward simultaneous pollutant removal and energy conversion. Herein, we report a novel Cu-Cu 2 O/carbon nanofibers (CNFs) photocathode, synthesized via an electrospinning-calcination method, in which the Cu-Cu 2 O heterostructures are uniformly anchored onto conductive CNFs rich in oxygen vacancies. As a proof of concept, a dual-photoelectrode PFC system was constructed to evaluate the performance of the Cu-Cu 2 O/CNFs photocathode. The PFC achieved an 83 % degradation rate for Rhodamine B (RhB) in 2 h and a maximum power density (P max ) of 42.99 μW/cm 2 , markedly outperforming the commercial Cu 2 O-based cathode PFC system. Moreover, the PFC system assembled with the Cu-Cu 2 O/CNFs photocathode exhibited consistent degradation efficiency and power output over multiple cycles, demonstrating that the cathode plays a crucial role in ensuring the long-term stability of the system. Experimental and theoretical calculation results confirm that the unique local electronic structure and coordination environment at the Cu/Cu 2 O interface promote O 2 adsorption and lower the energy barrier for the oxygen reduction reaction (ORR). This work demonstrates a rational strategy for designing high-efficiency Cu-based photocathodes and offers new insights into optimizing photoelectrocatalytic materials for environmental and energy applications.
