The rapid detection of polyethylene terephthalate (PET) nanoplastics (PET NPs) is hindered by their low concentration, high mobility and lack of a distinguishable interface with other nanoplastics. In this study, we developed an SnS 2 @MoS 2 /APTES amino-functionalized photoelectrochemical sensor capable of detecting PET NPs with high specificity. The SnS 2 @MoS 2 heterojunction synthesized via in situ hydrothermal synthesis and the APTES self-assembled amino-functionalized interface enable PET NPs to interact with amino-functionalized interface at multiple sites through oxygen-containing groups such as ester groups, carbonyl oxygen and ether oxygen. The sensor exhibits a detection range of 0.5-800 μg mL −1 for PET NPs, with a detection limit of 0.17 μg mL −1 . DFT calculations further indicate that the PET-APTES system exhibits a lower adsorption energy (−1.37 eV) and a more significant interfacial charge rearrangement, demonstrating that the APTES amino siloxane interface exhibits a polymer structural selectivity toward PET. Furthermore, this PEC sensor exhibits good recovery rates (96.04%-102.76%) in practical water samples such as seawater, bottled water and tap water. It provides a new method for interface recognition and signal conversion for the specific PEC detection of PET nanoplastics.

Poly(vinylidene
fluoride) (PVDF) has garnered extensive attention
for flexible applications, yet its practical utilization is severely
hampered by its limited piezoelectric response, the demand for high-voltage
poling, and the difficulty in controlling the oriented amorphous fractions
(OAFs). Herein, we demonstrate a thiourea (TU) cocrystallization strategy
to efficiently regulate the phase evolution in PVDF toward superior
piezoelectricity. PVDF/TU complexes are fabricated via electrospinning,
followed by TU removal to obtain coalesced PVDF ( c -PVDF). The c -PVDF film exhibits a high crystallinity
of 61.8% and a dominant content of polar β/γ-crystal phases.
More importantly, the c -PVDF film is capable of generating
a substantial fraction of OAFs and distinct dipole orientation under
moderate-to-low electric fields (<70 MV/m), far below conventional
poling voltages. Systematic structural characterizations reveal that
OAF content evolves nonmonotonically with poling field and plays a
decisive role in piezoelectric performance. The optimized c -PVDF exhibits a high piezoelectric coefficient ( d 33 ) exceeding 70 pC/N at a poling field of only
55 MV/m, displaying low-field high- d 33 characteristics compared to state-of-the-art PVDF-based piezoelectric
materials. Furthermore, the poled c -PVDF film exhibits
outstanding voltage outputs toward finger bending and airflow stimuli,
demonstrating promising potential in flexible sensing. This work establishes
an energy-efficient route toward high-performance piezoelectric PVDF,
and provides mechanistic insights into OAF-governed piezoelectric
enhancement, which will facilitate the rational design of high-performance
electroactive polymer materials.

Chemiluminescence (CL) biosensors have attracted extensive attention in biomarker detection owing to their high sensitivity and simplicity. However, the advancement of high-performance CL-functionalized nanoparticles (NPs) continues to encounter challenges, such as achieving high luminescence efficiency, ensuring good stability, and enhancing functionality. In this work, CL-functionalized magnetic NPs (CoFe 2 O 4 @TA@luminol-Ag NPs) were successfully synthesized. CoFe 2 O 4 NPs were modified with tannic acid (TA) and effectively coated with luminol and silver NPs (Ag NPs) on their surfaces. This configuration efficiently catalyzes the luminol-hydrogen peroxide (H 2 O 2 ) CL system, thereby significantly enhancing the CL signal. A highly sensitive biosensing platform for the detection of glucose, uric acid, and cholesterol in human serum was developed. A mixture of glucose oxidase (GOD)/glucose, uricase/uric acid, or cholesterol oxidase (ChOx)/cholesterol, which are capable of generating H 2 O 2 , was combined with CoFe 2 O 4 @TA@luminol-Ag NPs to generate a CL signal. The developed CL sensing platform was applied for the sensitive and quick detection of glucose, uric acid, and cholesterol in human serum samples. The concentrations of glucose, uric acid, and cholesterol present excellent linear correlation with the CL signal, with detection limits below 1.51 × 10 –11 M, 6.93 × 10 –12 M, and 2.44 × 10 –11 M, respectively. This biosensor combines the simplicity of magnetic separation with the specificity of enzymatic reactions and the enhanced signal amplification capabilities of nano-catalysis, demonstrating strong anti-interference properties, ease of operation, and good selectivity.

High-performance underwater adhesives are essential for
marine
engineering. But their application is hindered by hydration layer
interference, poor durability, and organic solvent pollution. In this
work, the reactive deep eutectic solvent (DES) was formed via intermolecular
hydrogen bonding reactions between thiourea and trioctylmethylammonium
chloride (TOMAC), providing a mild and green strategy to introduce
thiourea into the polyurethane (Thiourea-PU) adhesive. Thiourea functions
as a “polar hydrophobic” hydrogen-bonding motif, which
is beneficial to underwater adhesion. On the other hand, by utilizing
the reaction between isocyanate groups and water molecules, Thiourea-PU
adhesive disrupted the hydration layer and enhanced cohesive strength.
It exhibited strong underwater adhesion on various substrates, reaching
a maximum strength of 7.88 MPa on steel. And its strength can retain
90% of the maximum value after 6 months of water immersion. Meanwhile,
Thiourea-PU adhesive exhibited outstanding stability in harsh environments
(e.g., simulated seawater, acidic, and alkaline conditions). The incorporation
of TOMAC endowed the adhesive with extremely high antibacterial efficacy
(≥99.9999%). This work provides a reactive DES strategy for
the fabrication of high-performance Thiourea-PU underwater adhesive
with excellent durability, strong adhesion, complex environment resistance,
and antibacterial property, holding broad application potential.

Peroxymonosulfate (PMS)-assisted photocatalytic degradation represents an efficient advanced oxidation process for water purification. In this study, a novel SrTiO₃/Cu₂SnS₃ heterojunction was synthesized via a hydrothermal method, which was employed for visible-light-driven PMS activation to degrade norfloxacin (NOR). The STO/CTS-2 (n SrTiO₃ /n Cu₂SnS₃ = 2) composite exhibited superior catalytic performance, achieving 92.65% NOR degradation within 60 min, attributed to enhanced charge separation and efficient PMS activation. Comprehensive characterization confirmed the heterostructure formation, optimized band alignment, and improved light absorption. Radical trapping experiments revealed that superoxide radicals (•O₂⁻) dominated the degradation process, with additional contributions from SO 4 •⁻ , •OH, 1 O 2 , and h⁺. A plausible NOR degradation pathway and the underlying PMS activation mechanism were proposed. This study provides new insights into visible-light-driven PMS activation and presents an effective strategy for antibiotic wastewater treatment.

DTU suppresses curvature-accelerated copper nodule growth. • In situ SHINERS reveals geometry-dependent DTU adsorption on Cu. • Multiphysics simulation links nodule height to apex thickening. • DTU smooths nodular and planar Cu deposits in acidic electrolyte. Copper nodulation is a critical interfacial instability in copper electrodeposition under electrorefining-relevant acidic CuSO₄/H₂SO₄ conditions, where protrusion curvature intensifies local current density, Cu 2+ flux, and preferential deposition. Here, 1,3-diethyl-2-thiourea (DTU) was evaluated as a thermally durable thiourea analogue for suppressing curvature-accelerated nodule growth on a model copper nodular electrode containing nodular surface (NS) and planar surface (PS) regions. Electrochemical measurements, in situ shell-isolated nanoparticle-enhanced Raman spectroscopy (SHINERS), COMSOL simulations, density functional theory (DFT) calculations, and deposit characterizations were combined to correlate local current focusing, additive-related interfacial responses, and deposit evolution. COMSOL simulations showed that increasing nodule height intensified current focusing, with the maximum local current density reaching 366 A m −2 on the 2 mm nodule. Compared with thiourea (TU), DTU induced stronger cathodic polarization, decreased the anodic stripping response, delayed nucleation transients, increased charge-transfer resistance, and introduced an additional adsorption-related interfacial polarization response. Thermal degradation analysis demonstrated the higher solution-phase durability of DTU, while DFT calculations suggested stronger relative DTU–Cu interactions on representative Cu surfaces. Cu 2+ -free SHINERS revealed potential-dependent and spatially heterogeneous TU/DTU-related interfacial responses, with DTU maintaining clearer molecular signals over a broader cathodic potential range. SEM and AFM confirmed that DTU reduced the average surface roughness from 84.8 ± 6.2 to 22.3 ± 1.7 nm on the NS and from 55.3 ± 4.4 to 9.14 ± 0.8 nm on the PS. Overall, DTU suppresses curvature-accelerated nodule growth by inducing adsorption-mediated kinetic inhibition, thereby weakening the conversion of curvature-enhanced current density into excessive local copper growth.

CoS/C nanofibers were constructed via MOF-template-assisted interfacial engineering. • Rich CoS/C interfaces and defect sites enable strong broadband microwave attenuation. • Gradient periodic structures further regulate multiband absorption and RCS reduction. Developing fibrous microwave absorbers with balanced electromagnetic attenuation, broad effective absorption bandwidth, and radar-scattering suppression capability is important for electromagnetic protection and stealth-related applications. Herein, CoS/C composite nanofibers were fabricated through electrospinning, surface-confined Co-MOF growth, carbonization, and subsequent sulfidation. The obtained one-dimensional composites consist of a PAN-derived conductive carbon framework decorated with CoS nanoparticles, producing CoS/C heterointerfaces and N/O/S-associated defect sites. By regulating the cobalt precursor content, the dielectric response and impedance matching of the composites were effectively tuned. The optimized CSN-6 sample achieves a minimum reflection loss of −61.33 dB at a thickness of 2.27 mm and an effective absorption bandwidth of 6.32 GHz at 2.31 mm, indicating a favorable balance between dielectric attenuation and impedance matching. Electromagnetic-parameter analysis suggests that the enhanced absorption mainly originates from conduction loss in the interconnected carbon-fiber network, CoS/C interfacial polarization, heteroatom/defect-induced dipolar relaxation, and possible multiple reflection/scattering within the fibrous architecture. CST simulations based on the measured electromagnetic parameters further show that the CSN-6-based absorber achieves a maximum simulated radar cross-section reduction of 17.53 dB relative to a perfect electric conductor at 14.56 GHz. Moreover, a simulation-guided gradient periodic unit cell was proposed as a proof-of-concept structural design, generating multiple absorption responses at 2.57, 7.56, and 13.47 GHz. This work provides an interface-regulation and structure-simulation strategy for developing dielectric-loss-dominated CoS/C fibrous microwave absorbers.

The electrocatalytic reduction of CO2into value-added chemicals offers a promising route to mitigate greenhouse gas emissions, yet the uncontrollable structural reconstruction and surface rearrangement of electrocatalysts during operation often lead to severe activity degradation. Herein, we reveal that Bi2O2SO4(BSO) undergoes an irreversible phase transformation into Bi2O2CO3(BCO) nanosheets accompanied by the partial reduction of Bi3+to metallic Bi0under cathodic potentials. A series of BCO/BSO heterojunction catalysts with tunable compositions are synthesized via a mild in situ ion-exchange method. To circumvent the detrimental effects of this dynamic reconstruction, we devise a pre-activation strategy that deliberately completes the structural evolution prior to electrocatalysis. The optimized 20%-BCO/BSO heterojunction achieves a remarkable Faradaic efficiency of 98.4% for formate production in a flow cell at elevated potentials, with >95% FE(HCOOH)over a wide potential window (−0.8 to −1.7 V vs. RHE). In situ infrared spectroscopy elucidates that the reconstructed interface can promote CO2adsorption, stabilize the *OCHO intermediate, and facilitate HCOOH desorption. This work provides experimental evidence of the reconstruction behaviour of bismuth-based catalysts and offers a rational design method for constructing structurally stable heterojunction electrocatalysts.

Heterojunction structure MOSF NCs serve as an “electron reservoir”. • MOSF NCs transport electrons into bacteria via the surface Fe 3+ /Fe 2+ cycle. • Electronic attack on the CoQ-mediated respiratory chain of bacteria. • This study built a real-time fluorescence system for bacterial ETC interference. Although the phenomenon of current flow between bacteria and nanomaterials has long been observed, the direction of electron flow and specific interaction sites remain unclear. To address this, we designed a molybdenum (Mo) - based heterojunction electron reservoir (MOSF nanocrystals), enabling rapid Mo 6+ /Mo 4+ cycling, and introduced Fe as a mediator to shuttle electrons into bacteria through surface Fe 3+ /Fe 2+ redox. Upon contact with bacteria, MOSF nanocrystals (NCs) have the potential to block the coenzyme Q (CoQ)-mediated electron transport chain (ETC), causing energy depletion and bacterial death. This study also pioneers the development of a real-time fluorescent detection system to monitor electronic interference with bacterial ETC. This system can track how electrons in MOSF NCs inhibit bacterial deoxyribonucleic acid (DNA) replication, which is attributed to the inhibition of adenosine triphosphate (ATP) synthesis. By integrating transcriptomic and biochemical analysis techniques, we deduced at the atomic level that the antibacterial effect likely stems from the disruption of CoQ on the bacterial cell membrane, which in turn blocks the bacterial ETC. This study proposes an effective antibacterial nanoenzyme and a novel detection system, and provides an in-depth exploration of electron interference at the molecular level, advancing the development of bioenergetic therapeutics. We designed a strategy utilizing a Mo-based heterojunction as an electron reservoir (MOSF NCs), enabling rapid electron transfer between Mo 6+ in MoO₃ and Mo 4+ in MoS₂. Additionally, we introduced iron as an electron transfer mediator between the nanomaterials and the bacteria, thereby regulating the electron flow between them and ultimately achieving the goal of bacterial inactivation. Concurrently, this study pioneered the development of a real-time fluorescent detection system for monitoring electronic interference with the bacterial ETC. This system enables direct visualization of how electrons from MOSF NCs inhibit bacterial DNA replication, a process attributed to the suppression of ATP synthesis.

Scallion-inspired 3D CMC@NF evaporator was prepared. • Ultrahigh ER of 6.17 kg·m −2 ·h −1 achieved under 1-sun irradiation. • Evaporation enthalpy significantly reduced from 2415 to 828 kJ·kg −1 . • 3D CMC@NF exhibited excellent salt resistance and stable desalination. Due to its ease of operation and minimal environmental impact, solar-driven evaporation technology holds significant potential in addressing the worsening global water crisis. Inspired by the multi-layered coiled scallion, a 3D g-C 3 N 4 /MoS 2 /chitosan hydrogel@nickel foam (CMC@NF) evaporator was fabricated by decorating photothermal g-C 3 N 4 and MoS 2 , along with hydrophilic chitosan onto porous 3D nickel foam. Remarkably, water evaporation enthalpy decreased significantly from 2415 to 828 kJ·kg −1 due to the presence of hydrophilic chitosan. The multi-layered coiled structure of the scallion-like CMC@NF-2 enhances solar reflection and refraction, and enlarges the water evaporation area through its hierarchical interfacial design. Leveraging synergistic material advantages and optimized geometric configuration, the CMC@NF-2 evaporator attained an ultrahigh water evaporation rate of 6.17 kg·m −2 ·h −1 (normalized to the top-irradiation projected area). The CMC@NF-2 system also exhibited outstanding outdoor water evaporation of 74.54 kg·m −2 ·d −1 , an output adequate to satisfy the daily water requirements of 23 adults (based on a standard of 3.2 L·person −1 ·day −1 ). This study significantly enhances the capabilities of existing solar desalination techniques for delivering portable, cost-effective freshwater supplies, and simultaneously provides a thorough physical interpretation and actionable optimization frameworks for CMC@NF-2 systems.

The commercial deployment of lithium–sulfur batteries remains largely obstructed by the notorious shuttling behavior of lithium polysulfides (LiPSs) alongside their slow redox kinetics. Herein, a synergistic heterostructure composed of SnS and CoS nanoparticles (SnS-CoS@rGO) is developed as a multifunctional interlayer for separator modification. The SnS-CoS@rGO heterojunction integrates the strong chemisorption capability of SnS and the superior catalytic efficiency of CoS, while the interfacial electric field significantly accelerates interfacial charge transfer. Consequently, the SnS-CoS@rGO-modified separator effectively traps LiPSs and promotes their rapid catalytic conversion. With the SnS-CoS@rGO separator, the Li–S battery exhibits a remarkable first-cycle discharge capacity of 1528.2 mAh g –1 at 0.1 C and maintains exceptional long-cycle durability after more than 1000 cycles at 1 C, with a mere capacity degradation rate of 0.0375% cyclically. Furthermore, the modified separator exhibits favorable lithiophilicity and flame retardancy, thereby effectively impeding the growth of lithium dendrites and enhancing the battery safety performance. This study demonstrates the potential of SnS-CoS@rGO heterostructured electrocatalysts, providing an innovative avenue for designing advanced Li–S batteries.

Construction of a novel Z-scheme MIL-88@CuS heterojunction that couples photocatalysis with a Fenton-like reaction system. • MIL-88@CuS achieves synchronous photocatalysis/Fenton-like synergistic degradation of tetracycline. • The Z-scheme mechanism and built-in electric field significantly promote charge separation and interfacial electron transfer. • Effectively accelerate the redox cycle of Cu(II)/Cu(I), continuously generating highly active OH free radicals. • Achieves 93% tetracycline degradation within 60 min under visible light, with significantly enhanced performance. The widespread discharge of antibiotic residues into natural water environment have become a new water pollution problem, posing significant risks to aquatic ecosystems and human health. Herein, we report the utilization of a Z -scheme MIL-88@CuS nanocomposite that functions as a synergistic photocatalysis-Fenton-like system for the degradation of tetracycline antibiotics (TC). Mechanistic investigations reveal that the built-in electric field and Z-scheme electron transfer channel in MIL-88@CuS greatly facilitates charge separation and accelerates electron transfer to the CuS surface, thus boosting Cu(II)/Cu(I) circulation and producing more active hydroxyl radical (·OH) for TC oxidation degradation. As a result, the as-prepared MIL-88@CuS exhibits excellent photocatalytic TC degradation activity with the removal efficiency of 93% in 30 min under visible-light irradiation, much higher than that of simple MIL-88 or CuS samples. This work may provide an efficient and low-cost strategy for the remediation of antibiotic-contaminated water. Herein, we report a Z -scheme MIL-88@CuS nanocomposite as the synchronous photocatalysis-Fenton-like system to eliminate TC, which can accelerate the one-electron redox cycle of Cu(II)/Cu(I) and produce more active ·OH radicals for efficiently TC degradation.
