Organic electrochemical transistors could be used in in-sensor computing and wearable healthcare applications. However, they lack the conformity and stretchability needed to minimize mechanical mismatch between the devices and human body, are challenging to fabricate at a scale with small feature sizes and high density, and require miniaturized readout systems for practical on-body applications. Here we report a wearable in-sensor computing platform based on stretchable organic electrochemical transistor arrays. The platform offers more than 50% stretchability by using an adhesive supramolecular buffer layer during fabrication that improves robustness at interfaces under strain. We fabricate stretchable transistor arrays with feature sizes down to 100 μm using a high-resolution six-channel inkjet printing system. We also develop a coin-sized data readout system for biosignal acquisition. We show that our coin-sized, smartwatch-compatible electronic module can provide wearable in-sensor edge computing.

Vascular calcification (VC) poses significant challenges in cardiovascular health. This study employs single-cell transcriptome sequencing to dissect cellular dynamics in this process. We identify distinct cell subgroups, notably in vascular smooth muscle cells (VSMCs), and observe differences between calcified atherosclerotic cores and adjacent regions. Further exploration reveals ID3 as a key gene regulating VSMC function. In vitro experiments demonstrate ID3′s interaction with USP1 and E12, modulating cell proliferation and osteogenic differentiation. Animal models confirm the critical role of the USP1/ID3/E12/P21 axis in VC. This study sheds light on a novel regulatory mechanism, offering potential therapeutic targets. 1.

In this study, carbon nanorods (CNRs) were synthesized via a surfactant@salt self-assembly strategy, overcoming the limitations of conventional carbon nanomaterials in morphology control. Sodium dodecylbenzenesulfonate (SDBS) served as the carbon precursor, while sodium chloride (NaCl) acted as a structural spacer to guide nanorod formation. The synthesized SDBS@NaCl CNRs were systematically characterized by SEM, XPS, FT-IR, XRD, and Raman spectroscopy. The results demonstrate that amorphous carbon nanorods with a partially graphitized ordered structure have been successfully synthesized. The CNRs feature dominant oxygen-containing functional groups (C–O, C = O), uniform diameters (∼60 nm), and tunable lengths (1200 ± 400 nm), achieving an exceptional L/D ratio of up to 30. This work not only validates the efficacy of the salt-mediated self-assembly approach but also underscores its potential for designing advanced carbon nanostructures with tailored dimensions and surface properties, paving the way for multifunctional applications in energy storage and catalysis.

A poly( N -vinylpyrrolidone)-graphene oxide (NVP-GO) composite with high adsorption capacity for methylene blue (MB) was synthesized and comprehensively characterized using SEM, XRD, FT-IR, TG, elemental analysis, nitrogen physical adsorption, and XPS. The adsorption of MB onto NVP-GO was examined in relation to several variables, including contact time, adsorption temperature, initial concentration of MB, and pH. Adsorption kinetics, isotherms, and thermodynamics were thoroughly investigated. The adsorption kinetics followed the pseudo-second-order model, and the Langmuir isotherm model indicated a monolayer adsorption pattern of MB onto NVP-GO, with the maximum adsorption capacities ranging from 116.6 to 161.3 mg·g −1 at temperatures between 25 and 45 °C. Thermodynamic assessments and activation energy calculations demonstrated that the adsorption process was spontaneous, endothermic, and controlled by chemical activation. XPS analysis highlighted the significance of electrostatic interactions, n–π interactions, π–π stacking, and hydrogen bonding in mediating the adsorption mechanisms between NVP-GO and MB. Notably, NVP-GO maintained stable adsorption efficiency over three consecutive adsorption–desorption cycles, highlighting its potential as a promising adsorbent for wastewater treatment. Graphical

Polymer nanocomposites with high energy density hold great promise for the future miniaturization of dielectric capacitors in modern electronics. However, their performance is limited by the poor dispersion of inorganic fillers and severe interfacial electric field distortion. To address the above challenges, ultrathin two-dimensional (2D) BiOCl nanosheets are employed as the nanofiller for the first time, achieving excellent energy storage performance for the PMMA-based nanocomposites. Remarkably, the nanocomposite film with 0.5 wt% 2D BiOCl exhibits an outstanding energy storage density of 13.28 J/cm 3 and charge-discharge efficiency of 86.11 %, which is 108 % and 13.4 % higher than that of the pristine PMMA . Furthermore, the underlying enhancement mechanism is elucidated by finite element simulations. This work highlights the exceptional potential of 2D BiOCl as a novel nanofiller for designing high-performance polymer nanocomposites.

Near-infrared (NIR) luminescent materials are promising NIR light sources for multifunctional applications; providing a strategy to tailor the emission and enhance the performance of NIR phosphors is crucial. Herein, a green HF-free synthetic strategy is realized to tune the NIR emission advantageously by substituting on the adjacent octahedral, completely different from breaking the d–d parity forbidden transitions of Cr3+ through conventional lattice distortion. Broadband NIR phosphor K2Na1−xLixAlF6:Cr3+ with excellent thermal quenching resistance is prepared using the hydrothermal method. Controllable emission tuning from 726 to 765 nm and broadening full width at half-maximum from 105 to 130 nm, is achieved by substituting Li+ for Na+, resulting from weakening the crystal field and increasing electron–phonon coupling. Lithium ions play a critical role in suppressing nonradiative relaxation of the emission centers, thereby significantly enhancing the emission intensity of K2NaMF6:Cr3+ (M = Al, Ga, In) phosphors. The as-fabricated prototype NIR phosphor-converted light-emitting diode device, exhibits significant promise in the fields of night vision and information encryption. This study provides an effective design strategy for developing broadband NIR luminescent materials with high efficiency and good thermal stability.

The synergistic treatment of pollutants in water by radical and non-radical pathways based on photo-like Fenton-activated peroxydisulfate (PDS) has received much attention from researchers. However, clarifying the structure–activity relationship between the photocatalyst structure and the dual-pathway degradation mechanism is difficult. Herein, the flower-like nickel–iron layered double hydroxide containing oxygen vacancy (NiFe-LDH-V O ) was constructed by dual-hydrothermal method. The NiFe-LDH-V O /PDS/light system exhibited excellent degradation performance (93.1%) for norfloxacin (NOR). Notably, the apparent rate constant exceeded pristine NiFe-LDH by 2.6 times. The results of experiments, characterization and DFT calculations indicated that the enhanced degradation activity was attributed to the dual-pathway of radical and non-radical induced by V O on the catalyst surface. V O can not only improve the migration and separation efficiency of photogenerated carriers, which ensures the energy base of PDS activation, but also act as the active site of both radical pathway and non-radical pathway. In particular, V O can change the adsorption conformation of PDS, which enhances the adsorption of PDS on the catalyst and significantly reduces the energy barriers of the two activation pathways of PDS. The reasonable pathways for NOR degradation were proposed based on HPLC-MS and DFT calculations. In addition, the toxicity analysis of intermediates indicated lower developmental toxicity and mutagenicity compared to NOR. The present work provides innovative insights into the study of photocatalysts with dual degradation pathways and their mechanistic elaboration.

UNCA employs upconversion nanoparticles as signal probes for specific IGF-1 recognition. • Single-molecule counting enables IGF-1 detection with a low LOD of 6.04 pg/mL. • This method exhibits low cross reactivity and good recovery rates in milk products. There is rapidly growing interest in food nutrition assessment, particularly for nutrients present at low abundance. Here, an upconversion nanoprobe counting analysis (UNCA) is designed for ultra-sensitive detection of insulin-like growth factor-1 (IGF-1). The high sensitivity is attributed to the strong fluorescent intensity of upconversion nanoparticles (UCNPs) and highly specific antibody-antigen binding. Core–shell structured UCNPs are synthesized via co-precipitation followed by layer-by-layer epitaxial growth, and detection probes are constructed through hydrophilic ligand exchange and antibody conjugation. Two detection methods, traditional fluorescent intensity detection and single-molecule counting, are established with linear working ranges of 0.05–5000 ng/mL, which reach limit of detections (LODs) of 21.23 and 6.04 pg/mL, respectively. UNCA is further employed for analyzing three representative milk products, achieving recovery of 73.90%–107.09% with coefficients of variation (CVs) between 2.24% and 7.57%. This method demonstrates quantitative detection of trace-level IGF-1, especially via single-molecule counting. Download: Download high-res image (111KB) Download: Download full-size image

Polyethylene glycol (PEG), a versatile non-ionic surfactant with excellent biocompatibility and robust chemical stability, offers significant potential for the precise regulation of interfacial polymerization (IP). In this study, PEG was introduced into the aqueous phase as an additive to modulate the interfacial diffusion behavior of piperazine (PIP). By systematically optimizing its molecular weight, concentration, and terminal group parameters, a polyamide (PA) active layer with a smaller and more uniformly distributed pore structure was successfully constructed. This optimized architecture effectively strengthened both the size exclusion and charge repulsion mechanisms of the nanofiltration (NF) membrane. Consequently, the optimal MP 1000 -10 membrane exhibited highly competitive NF performance, achieving an impressive Na 2 SO 4 rejection of 98.0% and a high water permeance of 11.5 L m −2 h −1 bar −1 . More importantly, tailoring the PEG terminal groups facilitated targeted control over the pore size and surface charge properties, significantly enhancing the removal of structurally and physicochemically diverse emerging organic contaminants (EOCs). Across a broad set of experimental parameters, PEG modification consistently delivers improved separation performance for membranes. With excellent stability, high efficiency and economic feasibility, this strategy provides solid technical and theoretical support for developing advanced separation membranes targeting high-efficiency EOCs removal.

MoO 4 2− triggers rapid reconstruction of NiFe into corrosion-resistant LDH. • Surface MoO 4 2− stabilizes Fe, promotes high-valence Ni; detached ions sieve Cl − . • Delivers 1000 h durability at 500 mA cm −2 in natural seawater with 4.65 kW⸳h/Nm 3 H 2 . Suppressing the chlorine evolution reaction and mitigating chloride-induced corrosion remain central challenges for seawater electrolysis. Herein, this paper proposes an anion-accelerated directional catalyst reconstruction strategy. Guided by density functional theory (DFT) screening among a series of oxyanions, MoO 4 2− is identified as the optimal species to tailor the NiFe surface. MoO 4 2− not only drives the rapid and controlled reconstruction of NiFe into highly corrosion-resistant NiFe layered double hydroxide (LDH) but also optimizes the surface electronic structure, thereby lowering the oxygen evolution reaction (OER) energy barrier and enhancing intrinsic activity. The resulting MoO 4 2− /NiFe LDH delivers an overpotential of only 324.85 mV at 100 mA·cm −2 and exhibits extraordinary durability in natural seawater, operating stably at 500 mA·cm −2 for over 1000 h. Mechanistic investigations reveal a dual protection mechanism: surface-anchored MoO 4 2− stabilizes Fe sites while promoting the formation of high-valence Ni active species, and detached MoO 4 2− confined within the electric double layer functions as an ion sieve, selectively repelling Cl − and reinforcing corrosion resistance. When integrated with commercial platinum on carbon (Pt/C) in an anion exchange membrane (AEM) electrolyzer, the system achieves a cell voltage of only 1.96 V at 500 mA·cm −2 , stable operation for 200 h, and a remarkably low energy consumption of 4.65 kW·h/Nm 3 H 2 , outperforming conventional RuO 2 -based systems. The paradigm of anion-accelerated reconstruction is established, endowing earth abundant catalysts with excellent seawater corrosion resistance and bringing practical industrial scale hydrogen production from seawater electrolysis one step closer.

Nanofiltration (NF) for advanced drinking-water treatment has long been constrained by the need to remove contaminants while preserving beneficial mineral ions in health-oriented drinking water. Herein, an ethylene-glycol (EG)-regulated aqueous microenvironment was introduced to tailor the interfacial polymerization process. EG-mediated hydrogen bonding and modified interfacial thermodynamics jointly regulated piperazine diffusion, interfacial transport, and polymerization kinetics, producing polyamide NF membranes with enhanced negative charge surface density and a more uniform effective pore structure. Compared with the pristine membrane, the EG-20 membrane exhibited a thinner, more hydrophilic, and more negatively charged selective layer, together with a narrower pore-size distribution. The optimized EG-20 membrane achieved a permeance of 23.6 L m −2 h −1 bar −1 while maintaining Na 2 SO 4 rejection above 95.5%. In the treatment of natural surface water, dissolved organic matter removal reached approximately 92.1%, while partial passage of beneficial mineral ions was maintained, enabling effective organic contaminant removal with mineral preservation for health-oriented drinking water treatment. Moreover, high rejection of PFAS and antibiotics was maintained, mainly because steric exclusion and enhanced electrostatic repulsion compensated for the moderately enlarged effective pores. In addition, the membrane showed improved antifouling performance, as enhanced surface hydration and electrostatic repulsion reduced foulant adhesion and suppressed irreversible fouling. Overall, this microenvironment-regulation strategy provides a feasible route for developing NF membranes that integrate effective contaminant control, mineral preservation, and stable operation.

An ORR/EO-Cl system using commercial electrodes achieves efficient disinfection at 5 mA/cm 2 . • Cathodic H 2 O 2 consumes anodic free chlorine to generate 1 O 2 as the dominant bactericide. • The system suppresses chlorate and chlorite formation in real medical wastewater. • Multi-level oxidative damage to membranes, DNA, proteins and lipids causes irreversible inactivation. Electrochemical disinfection of chloride-rich medical wastewater faces an inherent trade-off: killing pathogens efficiently while avoiding toxic chlorate and chlorite formation. Here we show that coupling oxygen reduction at a commercial carbon felt cathode with chlorine evolution at a DSA@Ru/Ir anode breaks this trade-off. At 5 mA/cm 2 , cathodic H 2 O 2 rapidly consumes anodic free chlorine, generating singlet oxygen ( 1 O 2 ) as the dominant bactericidal species while suppressing chlorate and chlorite. In real hospital wastewater, chlorate drops from 0.66 to 0.39 mg/L, and the system inactivates 10 7 CFU/mL Escherichia coli in 5 min and Staphylococcus aureus in 10 min-using, the energy consumption was 0.1169 kWh/m 3 and 0.2338 kWh /m 3 , respectively. Quenching, flow cytometry, DNA electrophoresis, protein carbonylation and lipid peroxidation collectively confirm that 1 O 2 -driven oxidative stress causes irreversible membrane, DNA, protein and lipid damage. This work offers a low-energy, commercially viable strategy for electrochemical disinfection of real medical wastewater with intrinsic byproduct suppression.
