To address the low power output issue of Betavoltaic Batteries in practical applications, this paper proposes a novel isotope beta radiation energy conversion and storage system integrating a GaAs-based Betavoltaic Batteries with a low self-discharge lithium metal battery utilizing flake graphite. This system enables simultaneous collection, conversion, and storage of beta radiation energy. In experiments, we fabricated a lithium metal battery employing flake graphite as the cathode, lithium metal as the anode, and LiFSI in DME electrolyte supplemented with 4-n-pentyl-4′-cyanobiphenyl(5CB) additive. This battery was then connected to the GaAs-based Betavoltaic Batteries. Experimental results demonstrate successful energy harvesting from the Betavoltaic Batteries alone, which effecttively powered an LCD display.

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.

A facile one-step ball milling strategy was developed for direct synthesis of functionalized carbon adsorbents from natural flake graphite. The obtained ball-milled carbon materials (FG-BM) were systematically characterized and evaluated for their enhanced toluene removal performance. The obtained FG-BM exhibited a transformed morphology from stacked layers to micron-sized spherical particles with hierarchical porosity, a dramatically increased specific surface area, and abundant nitrogen/oxygen functional groups. These structural and chemical modifications significantly enhanced toluene removal performance, achieving 99.75% efficiency compared to 67% for pristine FG, with complete mineralization of toluene into non-toxic CO 2 rather than CO. Systematic optimization revealed that milling parameters, including particularly ball size, rotational speed, and cycle number, critically influenced performance, with 15 mm balls, 700 rpm, and 8 cycles delivering optimal results. The strategy demonstrated high generality, notably improving toluene removal efficiency for three commercial carbon adsorbents from 25 to 35% to 90.6–99.8%. Mechanistic studies identified pyridinic-N and oxygen-containing groups (C O, O-C=O) as key active sites, facilitating toluene adsorption and catalytic oxidation via intermediates such as benzaldehyde and benzoic acid. This work provides a scalable, solvent-free route to high-performance functionalized carbon adsorbents for efficient toluene removal.

Based on the confined flow - dual-network fixation mechanism, a self-adaptive composite phase change material was prepared. • In the chip thermal management, this composite phase change material could reduce the CPU temperature by up to 31.25 °C. • The composite phase change material has self-adaptive capability, reducing the interface thermal resistance by up to 78.56%. With the continuous trend toward high integration, chips are increasingly subjected to high heat-flux densities. However, excessive heat-flux density can induce chip overheating and warpage, increase local interfacial thermal resistance, and ultimately raise the risks of heat-dissipation failure and performance degradation. Therefore, thermal management has become a critical bottleneck restricting the further development of advanced chips, whereas conventional thermal interface materials (TIMs) still struggle to simultaneously accommodate chip warpage and maintain structural stability. To address this challenge, this study proposes a self-adaptive thermal-interface strategy based on a confined-flow and dual-network fixation mechanism. By constructing a calcium chloride tetrahydrate (CaCl 2 ·4H 2 O)/expanded graphite (EG)/in situ-grown silicon carbide nanowire (SiCnws) system, a high-efficiency heat-dissipating composite phase change material (CPCM) was developed, enabling simultaneous warpage conformability and structural stability. When applied to central processing unit (CPU) thermal management, the CPCM achieved a maximum core-temperature reduction of 31.25 °C. After 300 thermal cycles, the maximum fluctuation in the CPU core temperature was only 10.9 °C. Characterization results showed that, upon heating, the CPCM softened and conformed tightly to curved copper sheets, thereby reducing local thermal resistance. Interfacial thermal resistance measurements indicated that the adapted interface exhibited a resistance of 0.215 cm 2 ·K·W −1 , corresponding to a 78.56% reduction relative to the non-adapted state. This study provides a promising technical pathway and theoretical guidance for addressing chip warpage and high-heat-flux dissipation challenges.

With the rapid development of the photovoltaic and solar cell industry, the growing generation of crystalline silicon sawing/cutting waste has become an urgent problem. However, silicon (Si) is considered a promising alternative to graphite for next-generation high-energy density Li-ion batteries owing to its much higher theoretical capacity. Herein, photovoltaic silicon sawing/cutting waste is recycled as high-performance silicon/carbon anode active material of lithium-ion battery through an integrated strategy combining mechanical activation, acid leaching, dopamine self-assembly coating, and graphite buffering. The as-prepared silicon/carbon composite features a hierarchical architecture, which is composed of nanometer-sized Si particles covered with amorphous carbon and uniformly anchored in a conductive carbon matrix, effectively mitigating the severe volume fluctuation during charge/discharge. Enabled by the enhanced structural stability and interfacial compatibility, the activated silicon/carbon anode delivers a high reversible capacity of 641 mAh g −1 after 350 cycles at 0.5 A g −1 , with a capacity retention of 98.1%. Therefore, the investigation introduces an innovative method for recycling and enhancing the value of photovoltaic silicon sawing/cutting waste for further use, offering a sustainable and economically viable solution.

The pursuit of high-energy-density lithium-ion batteries demands high-silicon silicon-graphite composite negative electrodes, yet their commercialization remains hindered by interfacial incompatibility and mechanical instability. While an ideal binder must simultaneously achieve robust adhesion to both silicon and graphite, accommodate substantial silicon volume changes, and maintain high binder bulk stability, existing systems fail to harmonize these requirements. Here, we present a molecularly engineered binder that resolves this trilemma through interfacial-mechanical synergy. By integrating a hydrophobic-soft copolymer and hydrophilic-hard copolymer, our design enables amphiphilic interfacial adhesion and provides mechanical properties specifically tailored to accommodate silicon volume changes. A supramolecular crosslinker further reinforces interchain cohesion, ensuring binder bulk stability during long cycling life. This design enables a 2 Ah-level pouch cell to sustain 500 cycles at 0.3 C with 99.83% average Coulombic efficiency. At a commercial binder loading of 5 wt%, 1 Ah cells deliver over 2000 cycles at 1 C with an average Coulombic efficiency of 99.93%. Our work has the potential to not only resolve the long-standing trade-off between interfacial and mechanical stability in silicon-based negative electrodes but also provide a practical framework for designing next-generation binders targeting energy-dense, durable batteries.

A thiolated graphene/AuNPs nanointerface was constructed to enhance electron transfer. • An electropolymerized EMIP layer enabled selective epitope-based recognition of AFP. • A sensitive epitope-imprinted electrochemical biosensor was developed for AFP analysis. • The sensor exhibited a wide linear range (0.001–100.0 ng mL −1 ) and a low LOD of 0.069 pg mL −1 . • The biosensor enabled reliable AFP determination in spiked human plasma samples. Alpha-fetoprotein (AFP) is a clinically important serum biomarker for the early diagnosis of hepatocellular carcinoma. However, conventional AFP detection methods often suffer from limited sensitivity, selectivity and operational complexity. In this work, an electrochemical biosensor based on an epitope molecularly imprinted polymer (EMIP) was developed for the sensitive and selective determination of AFP. The sensing interface was constructed by electropolymerization of o -phenylenediamine ( o -PD) on a gold electrode sequentially modified with thiolated graphene (G–SH) and gold nanoparticles (AuNPs), using the AFP C-terminal dodecapeptide (KLISKTRAALGV) as the epitope template. The excellent analytical performance of the biosensor can be attributed to the synergistic integration of the EMIP recognition layer, G–SH, and AuNPs, which provide highly selective molecular recognition, an enlarged electroactive surface area and accelerated interfacial electron transfer. Under the optimized conditions, the proposed biosensor exhibited a wide linear range of 0.001–100.0 ng mL −1 , and a low detection limit of 0.069 pg mL −1 , together with excellent selectivity against NMP22, bovine serum albumin (BSA), human serum albumin (HSA), and neuron-specific enolase (NSE), good reproducibility, and satisfactory storage stability. Satisfactory recoveries obtained in spiked human plasma samples demonstrated its potential applicability for AFP determination in complex biological matrices. This work provides a sensitive and robust platform for AFP determination and highlights the potential of epitope-imprinted electrochemical biosensors for hepatocellular carcinoma screening and clinical biomarker monitoring. An epitope-imprinted electrochemical biosensor integrating an electropolymerized EMIP film with a thiolated graphene/AuNPs nanointerface was developed for AFP detection. The biosensor combines highly selective molecular recognition with enhanced electron transfer, achieving a 0.069 pg mL −1 detection limit and successful analysis of spiked human plasma samples.

Achieving efficient structural integration in epoxy asphalt remains challenging because the cured epoxy phase is prone to forming heterogeneous domains within the asphalt matrix, limiting the connectivity of the cured epoxy domains and overall performance. Here, we report a graphene oxide (GO)-assisted reactive bridging strategy that enables the molecular-level integration of epoxy resin (ER) and asphalt through a continuous GO-ER/asphalt crosslinked network. GO acts as a multifunctional reactive platform, where its oxygen-containing groups covalently anchor ER chains and provide active sites for subsequent curing with methyl tetrahydrophthalic anhydride (MTHPA). This sequential grafting and curing process transforms the epoxy asphalt system from a loosely dispersed multiphase structure into a chemically connected network with enhanced continuity and compatibility. The resulting GO-ER crosslinked network suppresses free volume, restricts molecular mobility, strengthens interfacial interactions, and improves thermal stability, thereby promoting more effective stress transfer and deformation resistance. Consequently, the GO-ER modified asphalt exhibits improved storage stability, high-temperature rutting resistance, elastic recovery, fatigue resistance, and tensile performance, while maintaining a favorable balance between strength and deformability. This work reveals a molecular-level reactive bridging mechanism and provides a general strategy for designing high-performance epoxy asphalt materials through GO-assisted interfacial regulation.

Graphite-based nanocomposites with nitrogen-rich covalent two-dimensional materials are promising for energy, catalytic and sensing applications, but their controlled construction remains challenging because both graphite and many covalent 2D materials consist of stacked sheets that are difficult to integrate homogeneously without prior exfoliation, dispersion, mixing, and restacking. Here, we explore a solvent-free strategy that uses melamine-confined graphite as a preorganized precursor for chemical transformations between graphene layers. We demonstrate that intercalated melamine can undergo reaction pathways analogous to those of bulk melamine, enabling not only the previously reported formation of graphite/g-C3N4composites but also the construction of a new graphite/melem composite. The same concept is further extended to multicomponent solid-state reactions by introducing pyromellitic dianhydride, enabling the formation of new graphite/polyimide-linked two-dimensional material composites from either melamine or melem precursors. Comparison of one-pot and stepwise routes shows that precursor preorganization within graphite improves framework preservation, structural continuity, and morphological homogeneity. Overall, this work presents graphite interlayers as confined reaction environments for transforming simple nitrogen-rich molecules into integrated graphite/2D-material composites, providing a scalable platform for exploring solid-state chemistry and hybrid material synthesis between graphene layers.

Agricultural
waste peanut shells are rich in cis -diol flavonoid
luteolin (LTL). However, conventional separation
materials suffer from insufficient specific sites, binding limitations
only under alkaline environments, and poor anti-interference performance
in complex matrices. Herein, an integrated fabrication strategy combining
in situ polymerization in mesoporous soft confined space and teamed
boronate (TBA)-functional molecular imprinting technology is innovatively
proposed. The hierarchical substrate of GO@MS was covalently assembled
via a thiol–ene click reaction, and a boronate affinity-imprinted
polymer was grown confinedly inside mesoporous channels. The TBA molecular
group as a functional monomer would be used for specific recognition
of LTL under neutral conditions. As a result, the prepared MI-GO@MS@GLYMO-TBA
exhibits high binding capacity (61.78 μmol g –1 ) for LTL at 308 K under physiological pH (7.4), with an equilibrium
time of 360 min. In addition, MI-GO@MS@GLYMO-TBA could be recycled
six times with a slight loss of 8.00% in adsorption. Meanwhile, the
commercially available LTL with 85% purity could be easily enriched
and further extracted with high selectivity (up to 93.67%). Remarkably,
the purified LTL solutions displayed lasting antibacterial performance
against Staphylococcus aureus ( S. aureus ) with an inhibition zone of 12.15 mm. Therefore,
the MI-GO@MS@GLYMO-TBA nanocomposite could be potentially developed
as a feasible and efficient method to achieve the goals of green sustainable
chemistry for precise identification and separation of LTL from complex
samples from agricultural wastes.

With the rapid advancement of electronic devices, electromagnetic
radiation has increasingly caused environmental interference, thereby
stimulating the development of flexible and wearable electromagnetic
interference (EMI) shielding materials. However, it remains challenging
to achieve EMI shielding textiles that simultaneously possess facile
fabrication, high shielding efficiency, and excellent durability.
Herein, a multilevel composite conductive network composed of reduced
graphene oxide (rGO) and poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate)
(PEDOT:PSS) was successfully constructed on silk fabric (SF) via a
layer-by-layer self-assembly strategy, resulting in a flexible EMI
shielding fabric (SF-PEDOT:PSS-rGO). Specifically, PEDOT:PSS formed
a uniform conductive coating through in situ polymerization, while
rGO further established a continuous conductive network and strengthened
the interfacial interactions among the different components. Benefiting
from the synergistic effect conductive network and interfacil interactions
among PEDOT:PSS, rGO, and SF, the resulting textile exhibited outstanding
EMI shielding performance with a maximum shielding efficiency of approximately
80%. Moreover, the fabric demonstrated excellent durability, retaining
over 80% of its initial shielding efficiency after 30 washing cycles,
while maintaining stable surface resistance and EMI shielding performance
during repeated folding and tape-peeling tests. This study provides
an effective strategy for constructing durable multilevel conductive
networks on textile substrates and offers valuable guidance for the
development of high-performance wearable EMI shielding materials.
