Flexible kesterite Cu 2 ZnSn(S,Se) 4 (CZTSSe) photovoltaics are attractive for lightweight and portable applications, but their efficiency remains limited by uncontrolled alkali-metal incorporation. Here we elucidate and exploit the distinct and complementary roles of Na and Li in controlling CZTSSe crystallization on flexible substrates. Our results show that Na promotes crystal growth, but its induced Se enrichment simultaneously drives large-scale SnSe x phase segregation. The incorporation of Li reshapes the free-energy landscape of Cu-related phases, promoting the formation of Cu x Se that consumes Se and thereby suppressing SnSe x phase growth while driving ordered phase evolution. This kinetic competition strategy yields high-quality CZTSSe films with reduced charge recombination loss and enables power conversion efficiencies of 14.5% (certified 14.2%) for flexible cells and 12.7% (certified 12.0%) for shingled modules. Our results provide mechanistic insights into alkali-metal regulation in chalcogenide solar cells and demonstrate a kinetic competition strategy that can be generalized to regulate crystallization in complex multinary materials.

Photocatalytic oxidative coupling of methane (POCM) is a promising strategy for the production of sustainable C 2+ hydrocarbons; however, it typically relies on large quantities of noble metals, such as gold, to serve as active sites for methyl coupling. In this study, we demonstrate that ZnO-supported gold nanoclusters with an average diameter of 1.1 nm provide a robust alternative to conventional gold nanoparticles, enabling efficient POCM even at ultralow gold loadings of 0.1 wt%. The optimized photocatalyst affords a C 2 –C 4 hydrocarbon production rate of 3.89 mmol/(g h) with 94.8% selectivity under 365 nm irradiation in a batch reactor. Results reveal that the abundant interfaces between highly dispersed gold nanoclusters and ZnO substrates facilitate charge carrier separation and promote a light-induced Mars–van Krevelen reaction pathway. Methyl adsorption causes gold nanoclusters to exhibit a more intense d- σ hybridization state compared to gold nanoparticles, enhancing electron transfer interactions and substantially reducing the transition-state energy barrier for methyl coupling.

In the study, we present a molten salt-assisted hard-templating strategy for synthesising cobalt and nitrogen-doped carbon nanoflowers (Co/N-CNFs) as high-performance electrocatalysts for highly sensitive and selective electrochemical dopamine detection. The hierarchical surface roughness and excellent conductivity of Co/N-CNFs, combined with their uniformly dispersed Co sites, facilitate exceptional electrocatalytic performance toward dopamine oxidation. Electrochemical measurements demonstrated that the Co/N-CNFs composite exhibited outstanding performance for dopamine sensing, featuring a broad linear response range from 1 to 1000 µM and an exceptionally low detection limit of 0.13 µM. Moreover, the sensor exhibited remarkable stability, excellent anti-interference capability, and high accuracy in actual sample analysis. The work presents an innovative design strategy for Co/N-doped carbon catalytic systems, enabling the detection of dopamine in spiked human serum samples.

Respiratory patterns (including breathing rate and depth) are critical vital signs for many disorders, such as asthma, sleep apnea, and chronic obstructive pulmonary disease. Breath sensors are capable of identifying abnormalities in respiratory patterns, which can evaluate the basic human body conditions during sports, surgery, and sleep and play a significant role in the healthcare system. However, present breath sensors have limitations for timely response and are incompatible with practical usage in daily activities. Here, we report an ultrafast-response flexible thermal sensor based on vanadium pentoxide nanorods (V 2 O 5 NRs) network for human respiration monitoring. A polyimide (PI) substrate comprises the fundamental component of the sensor, followed by a V 2 O 5 NRs sensing layer and a medical-grade encapsulating tape. A two-step method which involves hydrothermal synthesis and thermal oxidation is used to synthesize the V 2 O 5 NRs, Raman spectroscopy, XRD, and XPS are used to verify their structural quality. Such fabricated sensor has demonstrated the ability to accurately detect temperature in the range of 25–42 °C and excellent sensitivity (-1.55% °C −1 ) and linearity ( R 2 = 0.985) with a detection accuracy of 0.5 °C, enabling it to successfully sense changes in temperature of the exhaled/inhaled breath. Consequently, the sensor exhibits the enhanced breath sensing performance with a response time of 0.56 s and a recovery time of 0.97 s. Cyclic testing results reveal that the sensor exhibits exceptional consistency and repeatability in sensing human breath at various breathing rates, indicating its potential for long-term, ambulatory respiration monitoring. Furthermore, the sensor can be applied for prewarning of sleep apnea when integrated with an apnea alarm module developed with a microcontroller unit circuitry.

To tackle the high volatility, hydrophobicity and instability that limited cinnamaldehyde (CMA) in practical applications, CMA nanoemulsion (CNE) synergistically stabilized by cinnamic acid (CA) and Tween-80 were successfully prepared and characterized by ultrasonic emulsification treatment. The results showed that the CNE particle size was uniform (105.54 ± 2.14 nm). The CMA in CNE showed better slow-release properties under sealed conditions (22.68 ± 2.81% on day 10). The heat stability, freeze–thaw stability and storage stability of CNE showed good stability during 10 d storage period. Sensory and physicochemical property analyses indicated that the CNE was released headspace under non-contact conditions, reducing the impact on the flavor of chilled beef. It also effectively mitigated the increase in pH, juice loss and the increase in total volatile base nitrogen (TVB-N), thiobarbituric acid-reactive substance (TBARS), and total number of microbial colonies (TNC) of chilled beef during refrigeration.

Ceramic fiber aerogels have emerged as promising candidates for thermal insulation in extreme environments, yet their mechanical toughness and high-temperature stability remain critical bottlenecks. To address this challenge, we propose a multiscale structural engineering strategy integrated with scalable direct three-dimensional (3D) electrospinning technology to fabricate silicon–aluminum ceramic fiber aerogels (SACFAs) with a phase-locked amorphous/crystalline architecture. The entangled network constructed by crimped ribbon-shaped fibers reinforces the fiber junctions and provides ample deformation space. Concurrently, aluminum doping introduces Si–O–Al bonds and forms a phase-locked structure wherein nano-alumina/mullite crystallites are uniformly embedded within the amorphous silica matrix. This unique architecture intrinsically reinforces the fibers through grain boundary pinning, thereby synergistically enhancing both mechanical properties and thermal stability. The SACFAs exhibit a superior combination of tensile performance (a high tensile strength of 0.4772 MPa with a fracture strain of 47.58%), compressive resilience (complete recovery after 80% compressive strain, corresponding to a maximum compressive stress of 120.92 kPa), and near-zero Poisson’s ratio. The material maintains stable mechanical properties from −196 °C to 1200 °C, with a low thermal conductivity of 0.03254 W·m −1 ·K −1 , a low density of 22.70 mg·cm −3 , and a high porosity of 98.72%. Additionally, the direct 3D electrospinning method delivers a single-nozzle production rate of 1800 cm 3 ·h −1 , highlighting its scalability for industrial production. This work provides a promising strategy for developing lightweight, flexible thermal insulation materials for aerospace and advanced energy applications. Graphical

Two coordination polymers, CP1 and CP2, based on Cu(II) and Zn(II) ions, were synthesized and structurally characterized as fluorescent sensors for 1,10-phenanthroline, an important nitrogen-containing chelating agent widely used in coordination chemistry and industrial systems. Both materials exhibit good crystallinity, thermal stability, and intrinsic fluorescence. Their fluorescence sensing behaviors toward 1,10-phenanthroline were systematically investigated in aqueous media. CP1 and CP2 show high selectivity and sensitivity toward 1,10-phenanthroline, with Stern–Volmer constants of 1.11 × 10⁵ M⁻¹ and 6.95 × 10⁴ M⁻¹, and detection limits of 3.2 µM and 4.5 µM, respectively. In addition, both coordination polymers display good anti-interference ability and recyclability. Comparative studies reveal that the different sensing efficiencies of CP1 and CP2 are closely related to the distinct electronic properties of the Cu(II) and Zn(II) centers. Mechanistic investigations indicate that the fluorescence quenching mainly arises from coordination interactions between 1,10-phenanthroline and the metal centers. This work not only demonstrates the potential of coordination polymers as effective fluorescent sensors for phenanthroline detection, but also provides insight into the role of metal centers in regulating fluorescence sensing performance.

Infected wounds present a high clinical incidence, and current treatments are inadequate in both effectively eliminating bacterial biofilms and continuously promoting tissue regeneration. To address these challenges, we develop a microwave-responsive thermoelectric nanocomposite of zinc oxide-bismuth telluride (ZnO-Bi 2 Te 3 ) via hydrothermal synthesis for the treatment of biofilm infected wounds. The heterointerface within the nanocomposite enhances phonon scattering, while the ZnO component provides additional charge carrier transport pathways, collectively significantly improving the thermoelectric conversion performance. Under microwave irradiation, the ZnO-Bi 2 Te 3 rapidly generates substantial amounts of reactive oxygen species (ROS), enabling efficient penetration and eradication of biofilms with an antibacterial rate of 99.2%. After irradiation ceases, the ZnO-Bi 2 Te 3 utilizes the wound-environment temperature difference to continuously produce thermoelectric signals. The continuous thermoelectric signals, in synergy with the release of zinc ions, activate the MAPK pathway and promote protein synthesis, processing, and transport, thereby enhancing cell migration, differentiation, and angiogenesis, leading to continuous tissue regeneration. In a mouse model of MRSA-biofilm infected wounds, the ZnO-Bi 2 Te 3 loaded microneedles effectively clear the infection and accelerate healing. This study develops a microwave-responsive thermoelectric system for infected wounds through efficient biofilm clearance and sustained pro-regeneration. Graphical

A straightforward dip-coating method was proposed for the direct construction of three-dimensional NiO micro-nanorod arrays on nickel foam. The morphology and crystal structure were characterized by scanning electron microscopy and X-ray diffraction, respectively, confirming the beneficial growth and favorable crystallinity of the fabricated micro-nanorods. Electrochemical measurements revealed that the NiO micro-nanorod arrays electrode delivered a high specific capacitance of 1400 F g −1 at a current density of 1 A g −1 in 2 M NaOH electrolyte. Furthermore, an asymmetric supercapacitor was assembled using the fabricated NiO as the positive electrode and activated carbon as the negative electrode. At a current density of 0.5 A g −1 , the device achieved a energy density of 114.74 Wh kg −1 , while a maximum power density of 14 kW kg −1 was attained at an energy density of 73.84 Wh kg −1 . Remarkably, the device exhibited outstanding cycling stability, maintaining 100% capacitance retention and 99.1% Coulombic efficiency after 5000 charge–discharge cycles. This work presented a simple, safe, and efficient strategy for fabricating NiO micro-nanorod arrays structure, offering a promising route toward high-performance electrochemical energy storage devices.

Polyimide (PI) aerogels demonstrate significant potential in cutting-edge applications such as aerospace thermal protection and flexible sensors. However, their limited elasticity and flexibility, coupled with the common issue of volume shrinkage during preparation, hinder their ability to meet the stringent material requirements of flexible devices. In this study, the rigid diamine (PPDA) was partially replaced by the aromatic flexible diamine (BAPP) to copolymerize with (BPDA), forming a polyamic acid (PAA) precursor. Subsequently, NH 2 -SiO 2 nanoparticles were introduced to construct an organic–inorganic dual-crosslinked network, successfully yielding PI/SiO 2 composite aerogels. The resulting material exhibits high elasticity, good flexibility, and superior thermal insulation properties. The incorporation of BAPP significantly enhances the elasticity and flexibility of the material. After 50 radial compression cycles, the aerogel retains over 90% of its compressive strength. The incorporation of NH 2 -SiO 2 effectively suppressed drying shrinkage and reduced material density, endowing the aerogel with a low thermal conductivity (0.0285 W·m −1 ·K −1 ), high thermal stability (T 5% , 547 °C), and significant thermal insulation performance across a wide temperature range (− 40 to 300 °C). This study proposes a synergistic design strategy. It combines rigid–flexible copolymer chains with NH 2 -SiO 2 . The strategy effectively balances the flexural elasticity, thermal insulation properties, and structural stability of the aerogel. It demonstrates significant application potential in advanced thermal insulation fields. Graphical abstract

Polymers play a crucial role in our daily lives; however, achieving a balance among mechanical performance, resistance to high and low temperatures, and mild shaping remains challenging. Here, we report a water-triggered supramolecular polymer composed of cellulose and polymethyl methacrylate. Following water-induced transformation of a stretchable supramolecular network into a densified cross-linked domain, the resulting polymer exhibits a remarkable increase in tensile strength from 2.7 MPa to 61.7 MPa, representing more than a 22-fold enhancement, and a flexural strength of 97 MPa, while maintaining structural integrity across a temperature range of −196 °C to 200 °C. In addition, the polymer enables scalable water-mediated shaping and reinforcement even in seawater, surfactant wastewater, and dye wastewater, while retaining high mechanical performance. Economic analysis and recycling assessment demonstrate that this polymer is amenable to scalable production and has considerable market potential. This study provides a biomimetic formulation for the fabrication of high-performance supramolecular polymers and broadens their potential applications across diverse fields.

Electromagnetic pollution and radiation now extend to encompass millimeter waves, while the development of broadband millimeter-wave absorbers remains significantly hindered by lacking efficient loss mechanisms. High-entropy M-type ferrites are promising due to their excellent magnetic resonance and dielectric polarization, yet precise electromagnetic parameter regulation remains challenging because intermediate-phase impurities persist from insufficient configurational entropy. Herein, we propose an iron-deficient strategy to synthesize the single-phase Zr 4+ -doped high-entropy M-type ferrites. It is found that iron deficiency eliminates impurities by enhancing entropy and provides a more adaptable local structure. The synergistic effect of high entropy and iron deficiency amplifies the dielectric loss capacity, while Zr 4+ doping broadens the magnetic loss range by modulating natural resonance. This yields an ultra-broad absorption bandwidth of 12.18 GHz and ultra-thin matching thickness below 1 mm within the millimeter-wave atmospheric window around 35 GHz, offering insights for absorbers against electromagnetic pollution and radar stealth.
