The fabrication of sustainable solar-powered interfacial evaporators is essential for addressing global water scarcity challenges. Herein, we propose a new photothermal evaporator by applying a zirconium carbide-polypyrrole (ZrC-PPy) composite coating to a cellulose filter (CF) possessing enhanced photothermal conversion. The 3D photothermal evaporator is constructed by integrating a ZrC-PPy@CF evaporator onto triangular polyurethane (PU) foam. With a poor thermal conductivity of 0.078 W m −2 K −1 , the synthesized evaporator allowed effective heat localization under light. The evaporator produced an evaporation rate of 1.92 kg m −2 h −1 with a corresponding photothermal conversion efficiency of 89%. Additionally, the evaporator achieved over 99.9% rejection of common metal ions (Na + , K + , Ca 2+ , Mg 2+ ) from saline water, yielding high-quality freshwater. These findings highlight the ZrC-PPy@CF evaporator as a scalable and versatile platform for efficient wastewater treatment and desalination.

Macrocycle-based porous organic polymers (M-POPs) are promising adsorbents for uptake of iodine vapor and adsorption of organic micropollutants (OMPs) from water. Herein, two conjugated triaryl triazine-incorporated, calix[4]pyrrole-based porous organic polymers were prepared by diazocoupling reaction between 4,4′,4′'-(1,3,5-triazine-2,4,6-triyl)trianiline (TTTA) and two configurational isomers of resorcinol-modified calix[4]pyrroles (2α,2β-C4P and 4α-C4P), referred as CP-POP-1 and CP-POP-2, respectively. The obtained CP-POPs were gifted with good porosity, high nitrogen contents and conjugated triaryl triazines, while CP-POP-1 and CP-POP-2 exhibited high iodine vapor uptake at 4.27 g/g and 4.25 g/g, respectively. Charge transfer interaction was the main mechanism for iodine vapor uptake on the CP-POPs. Besides, the CP-POPs displayed preferred adsorption feature to cationic dyes, such as methylene blue (MB), crystal violet (CV) and rhodamine B (RB), while CP-POP-2 showed superior adsorption performance towards cationic dyes. The q m values of MB, CV and RB by CP-POP-2 were as high as 317.46, 373.13 and 471.69 mg/g, respectively. Thermodynamic studies discovered that the adsorption of cationic dyes upon CP-POP-2 was a spontaneous process, while mechanism researches confirmed that electrostatic, hydrophobic and host-guest interactions were involved for adsorption of cationic dyes upon CP-POP-2. In addition, CP-POP-2 could adsorb cationic dyes efficiently from water samples containing complex matrix and exhibited good reusability. The obtained results suggested the bright prospect of the CP-POPs in removal of environmental pollutants. Download: Download high-res image (222KB) Download: Download full-size image

Oxidative polymerization strengthens PPy hydrogels and optimizes evaporation enthalpy. • Ti 3 C 2 T x -PPy multilevel channels guide salt crystallization to evaporator edges. • Ti 3 C 2 T x -PPy evaporator delivers 4.63 kg m −2 h −1 , 35% higher than PPy. Solar-driven interfacial evaporation, which relies on localized photothermal conversion at the gas-liquid interface, represents an effective strategy for seawater desalination. However, continuous salt crystallization and deposition at the evaporation interface remain a critical bottleneck that limits long-term operational stability. Herein, we develop a Ti 3 C 2 T x -PPy composite hydrogel evaporator with multilevel mass-transport channels for solar seawater desalination and spatial regulation of salt crystallization. The incorporation of Ti 3 C 2 T x optimizes the internal pore network of the polypyrrole hydrogel, establishing hierarchical mass-transport pathways that promote the preferential migration of salts towards the evaporator edges, where crystallization subsequently occurs. Meanwhile, Ti 3 C 2 T x enhances the photothermal conversion capability of the system and modulates the hydrogen-bonding structure of water molecules, thereby effectively lowering the evaporation energy barrier. Under 1 sun illumination, the Ti 3 C 2 T x -PPy evaporator achieves an evaporation rate of 4.63 kg m −2 h −1 , while maintaining a clean surface and undiminished performance after 50 h of continuous operation. The evaporator also exhibits purification efficiencies exceeding 99% in hypersaline solutions, dye-contaminated wastewater and real seawater, and delivers an average daily water yield of over 25 L m −2 under natural sunlight. This work provides a promising strategy for the design of hydrogel-based solar desalination systems with high efficiency, excellent salt resistance and long-term operational stability.

To suppress the ever-increasing challenge of electromagnetic radiation pollution and exploit lightweight wave absorbers, enormous attention has been focused on aerogels. Herein, a sequence of Fe3C/Fe/NC aerogels with variable dielectric/magnetic ratios has been successfully synthesized by redox reaction, freeze-drying, and high-temperature calcination. Benefiting from the dielectric-magnetic coupling loss, optimized impedance matching, and structural advantages, the Fe3C/Fe/NC-2/PVDF composite displays optimal microwave absorption performance with a minimum reflection loss (RLmin) value of −59.03 dB at 2.53 mm under an ultralow filler loading of 3 wt %. Meanwhile, the maximum effective absorption bandwidth (EAB) of Fe3C/Fe/NC-3/PVDF composite nearly covers the entire X-band at 2.92 mm. Moreover, the radar cross-section (RCS) simulation results and infrared thermal images respectivelly verify their application potential in radar wave attenuation and the infrared stealth domain. The specific wave absorption mechanism is mainly ascribed to dielectric loss, including conduction loss and polarization loss, magnetic loss containing eddy current loss and exchange resonance, as well as multiple reflections and scattering caused by the porous structure. This study can effectively decouple the impedance matching and microwave dissipating ability by dielectric/magnetic ratio modulation and microstructure design, which is of great significance for the development of lightweight and advanced wave absorbers.

In an effort to address the inherent trade-off between electrostatic safety and combustion performance in solid propellants, a series of CuCr₂O₄/polypyrrole (PPy) composite catalysts with tunable microstructures was designed in this study. CuCr₂O₄/PPy composite catalysts with CuCr₂O₄ loadings of 10, 30, and 50 wt% were synthesized via the hydrothermal method and in-situ polymerization. The microstructural evolution was characterized by electron microscopy, X-ray diffraction, and N₂ physisorption. These composites were incorporated at 2 wt% into GATo propellants, a Composite Modified Double-Base (CMDB) propellant, and their effects on electrical resistivity, thermal decomposition, burning rate, and sensitivities were systematically evaluated. The specific surface area of the composites decreased progressively from 52.7 m²/g (10 wt% CuCr₂O₄, 1#) to 38.1 m²/g (50 wt% CuCr₂O₄, 3#), confirming a microstructural transition from a continuous PPy network to agglomerated CuCr₂O₄ particles. The composite with low CuCr₂O₄ loading (10 wt%) imparted the lowest electrical resistivity and the most significant safety enhancement, while slightly improving the combustion performance of the GATo propellant: the negative electrostatic sensitivity threshold increased by 38% (from 1.78 J to 2.45 J), and the impact sensitivity threshold improved by 150% (from 4.0 J to 10.0 J). In contrast, the composite with high CuCr₂O₄ loading (50 wt%) achieved the highest combustion performance while reducing the sensitivity of the GATo propellant: the burning rate increased by 44% (from 3.79 to 5.47 mm/s), and the exothermic peak temperature decreased by 5.3°C.

Peripheral nerve injury (PNI) remains a major clinical challenge because of the limited regenerative capacity of nerve tissue and the formation of an unfavorable inflammatory and fibrotic microenvironment after injury. In this study, a multifunctional conductive hydrogel-composite nerve conduit was developed by integrating an electrospun silk fibroin/polycaprolactone (SF/PCL) hollow conduit loaded with ursolic acid (UA) and an injectable SF/hyaluronic acid (HA) conductive hydrogel containing polydopamine-modified polypyrrole (PDA–PPY) nanoparticles. The electrospun conduit provided structural support, balanced wettability, sustained UA release, and relatively slow degradation, while the conductive hydrogel created a hydrated three-dimensional microenvironment with tunable porosity, swelling behavior, and mechanical properties. PDA modification reduced the aggregation of PPY nanoparticles, improved their dispersion stability and interfacial compatibility within the hydrogel matrix, and promoted the formation of a more homogeneous conductive network, thereby significantly enhancing hydrogel conductivity. In vitro studies demonstrated good cytocompatibility toward Schwann cells, inhibition of fibroblast proliferation and collagen-related secretion, regulation of macrophage polarization under inflammatory conditions, and enhanced cellular activity under appropriate electrical stimulation. These findings indicate that the developed conductive hydrogel-composite conduit integrates structural support, electrical conductivity, and biological activity, providing a promising multifunctional platform for further investigation in peripheral nerve repair.

Solar-driven advanced oxidation processes and interfacial water evaporation represent promising strategies to simultaneously address water pollution and freshwater scarcity. However, conventional photo-Fenton catalysts are predominantly powder-based and suffer from difficult catalyst recovery, inefficient H2O2utilization, and limited practical applicability. Herein, a multifunctional bacterial-cellulose-based composite membrane (BC-MTP) was designed by immobilizing 1T-2H MoS2and a tea-polyphenol/polypyrrole (TP/PPy) copolymer through a blending–copolymerization strategy. The three-dimensional BC network anchors the catalytic components and supports their repeated use, while the BC-MTP membrane achieves 88.2% tetracycline removal using 20 μL H2O2, four times lower than the dosage used for the corresponding powder catalyst. Because dissolved Fe was not quantified by ICP-OES or ICP-MS, the present results are interpreted as evidence of improved H2O2utilization and component immobilization rather than quantitative proof of suppressed iron leaching. The incorporation of 1T-2H MoS2and TP/PPy also provides strong broadband light absorption and photothermal conversion, yielding a solar-driven evaporation rate of 1.34 kg m−2h−1and an energy efficiency of 80.1% under the tested laboratory conditions. This work demonstrates a membrane platform integrating photo-Fenton degradation and solar-driven water evaporation for water-purification applications.

Photothermal aerogel fibers offer promise for intelligent
thermal management in extreme cold environments, yet their scalable
production is hindered by slow gelation kinetics, poor mechanical
strength, and limited dyeability. Herein, we report an in situ photo-cross-linking
strategy for the fast gelling fabrication of dyeable photothermal
aerogel fibers, using thermoplastic polyurethane (TPU) as the sheath
and methacrylated chitosan (CSMA) aerogel as the core. The photosensitive
CSMA core cross-links within 15 s under UV irradiation, enabling fast
sol–gel transition in a deionized-water coagulation bath within
1 min. The trade-off between dyeability and photothermal performance
is addressed by incorporating cesium tungsten bronze (CWO) nanoparticles
into the TPU sheath layer or in situ polymerizing polypyrrole (PPy)
in the CSMA core layer, whereby light-blue TPU/CWO@CSMA fibers and
near-white TPU@CSMA-PPy fibers were developed. Both fibers exhibit
excellent mechanical properties (tensile strength 3.1–3.3 MPa,
elongation >1600%) and low thermal conductivity (0.047 ± 0.0004
W·m –1 ·K –1 ), achieving
a good synergistic optimization of passive thermal insulation and
active photothermal heating performance. They also display good dyeability
for multicolored fabrication while maintaining strong photothermal
performance. TPU/CWO@CSMA fibers heat to 66.7 ° C under 1-sun
illumination and reach 19.2 ° C at −20 ° C via CWO’s
LSPR effect. TPU@CSMA-PPy fibers show mild, controllable warming (≈16
° C at −7 ° C; 20 ° C at 0 ° C) with slower
cooling. Outdoor tests confirm fabric temperatures remain in a mild
25–34 ° C range without overheating. This work overcomes
the long-standing technical bottleneck of conventional photothermal
aerogel fibers that are typically restricted to single, undyeable
colors, demonstrating promising potential for personal thermal management
and related applications.

The dielectric response of carbon-based single-atom (SA) absorbers is intrinsically constrained by the highly symmetric charge distribution of planar M-N 4 coordination motifs, which suppresses dipole polarization and limits electromagnetic wave (EMW) attenuation. Here, a nanocurvature-driven symmetry-breaking strategy is proposed to activate latent dielectric polarization at SA sites through geometric regulation. By combining click chemistry with template-assisted synthesis, metal SAs are anchored onto hollow nitrogen-doped carbon spheres with precisely tunable diameters, enabling systematic modulation of local nanocurvature. Theoretical calculations and experimental analyses reveal that curvature-induced surface charge accumulation disrupts the electronic symmetry at Ni-N 4 centers, markedly enhancing local charge density, dipole moments, and polarizability. Consequently, the optimized Ni/HNC-200 absorber achieves an ultralow minimum reflection loss of −74.1 dB, representing a staggering 390% enhancement over HNC-200 (−15.1 dB), and exhibits a reduced radar cross section of −70.49 dB m 2 . A flexible electronic patch further demonstrates over fivefold suppression of electric-field radiation from mobile phone chips. The universality of this mechanism is validated in Co- and Cu-based systems, establishing nanocurvature as a geometry-enabled design paradigm for high-performance SAs EMW absorbers.

Selective capture of structurally diverse molecules remains a major challenge in chemical separations. Here, we introduce dual-acidic deep eutectic solvents (DESs) in which Lewis acids modulate the Brønsted acidity, creating a synergistic environment for the simultaneous extraction of basic and non-basic nitrogen-containing molecules. Brønsted sites, activated by adjacent Lewis centers, preferentially bind basic heterocycles, while the Lewis sites coordinate with non-basic species, achieving unprecedented extraction efficiencies. Mechanistic studies combining FT-IR spectroscopy, density functional theory, and molecular electrostatic potential analysis reveal that proton transfer, Lewis acid–base coordination, and π–cation interactions collectively govern selective recognition. This dual-acidic design strategy is generalizable across different LA-metal DES compositions and robust against competing chemical species. Our findings demonstrate a rational approach to fine-tune cooperative acid functionalities, establishing a versatile platform for selective molecular capture and separations beyond conventional single-acid systems.

Achieving exceptional strain hardening is a promising strategy for simultaneously enhancing the strength and ductility of titanium matrix composites (TMCs). In this study, a novel carbon-based nanomaterial, namely polypyrrole (PPy), was used to fabricate TMCs reinforced with intragranular titanium carbide (TiC) through spark plasma sintering and hot rolling. Concurrently, face-centered cubic of titanium (FCC-Ti) was formed through the synergistic effects of high local stress field and interstitial solid solution oxygen atoms. The ultimate tensile strength and uniform elongation of the Ti-0.6PPy composites reached 1029 MPa and 11.3%, representing a 67% and 88% improvement over the pure Ti (614 MPa, 6.0%), respectively. The significantly enhanced strength was benefited from the O atoms solid solution strengthening and Orowan strengthening. Ex-situ EBSD combined with TEM characterization were conducted to analyze the microstructure of the deformed Ti-0.6PPy composites. It had revealed that dislocation hot spots moved from grain boundaries to the grain interiors and surrounded to the new formed FCC-Ti phase. This transformation enhanced the dislocation storage capacity, led to higher dislocation density and prolonged strain hardening, thereby achieved superior uniform elongation and ductility.

Constructing vanadium oxide/metal selenide heterostructure is a promising strategy to enhance the reaction kinetics and structural stability for high-performance sodium-ion batteries (SIBs) anode. However, achieving a uniform and robust heterointerface remains challenging due to the multivalent state transformation of the V and the thermodynamic stability difference between V O and V Se bonds. Herein, we design and synthesize the V 2 O 3 /Fe 3 Se 4 @C heterostructure via a facile liquid-phase reaction followed by a seleniziation method. The unique coordination environment in a ferric vanadate and the reduction potentials difference between Fe and V cations promote the formation of a well-defined heterointerface. Density functional theory calculations confirm the formation of a built-in electric field at the heterointerface, thereby accelerating the reaction kinetics. The electric field originates from the orbital hybridization, which promotes the formation of a robust Se V O bonding configuration. Meanwhile, the carbon coating maintains structural integrity by suppressing volume expansion during cycling. These synergistic effects effectively enhance the overall structural stability of the material. Thus, the prepared V 2 O 3 /Fe 3 Se 4 @C anode exhibits exceptional electrochemical performance, delivering a high specific capacity of 378.2 mAh g −1 at 0.5 A g −1 and 308.9 mAh g −1 at 8 A g −1 , and retaining a specific capacity of 313.8 mAh g −1 after 2500 cycles at 5 A g −1 . This work establishes a new electron orbital modulation strategy for exploring high-performance vanadium oxide-based anode materials for SIBs.
