Carbon nanosheets (CNS) have garnered significant interest as anode materials for potassium-ion batteries (PIBs) due to the excellent potassium storage kinetics and rate performance. Moreover, tuning the thickness of CNS can enhance the potassium storage performance by exposing abundant surface active sites and shortening the K + migration path. Herein, crystallization-induced thickness tuning of carbon nanosheets in polyvinyl pyrrolidone-potassium chloride (PVP-KCl) solution is reported to enhance the fast potassium storage. PVP with varying molecular weights is employed to induce the crystallization behavior of KCl, leading to the formation of KCl grains with controllable sizes. Concurrently, these KCl grains act as hard templates for dispersing the PVP molecules to fabricate carbon nanosheets on the surface during annealing. PVP with high molecular weight is beneficial for hindering ion migration to reduce crystal sizes, which can decrease the thickness of carbon nanosheets. The ultrathin structure exposes abundant potassium storage sites, endowing CNS with high reversible capacity (359.0 mAh/g at 100 mA/g). The reduction in the migration path of K + ions facilitate rapid ion and electron transport kinetics, resulting in rate performance with a capacity of 181.9 mAh/g at 1 A/g. Our work extends the application of the crystallization-induced strategy for controllable designing carbon nanosheets, and puts forward some conceptions on improving the potassium storage performance of carbon anode materials.

Conventional methods of preparing carbon nano in most cases prepare worm-like carbon nanomaterials in a single dispersed arrangement, agglomerated into a spherical worm-like carbon nano is more special and uncommon. Tetradecyl trimethyl ammonium bromide (TTAB) and potassium chloride were used as raw materials, and sphericity of worm-like carbon nano could be prepared by in situ carbonization method. This particular morphology is called worm-like carbon nanospheres. The yield of worm-like carbon nanospheres was calculated to be about 5‰ using tetradecyl trimethyl ammonium bromide as the carbon source. A series of characterization means such as SEM, FT-IR, Raman, XRD and XPS were used for characterization. The characterization results show that the size of worm-like carbon nanospheres is between 300 and 600 nm, relatively dispersed, and the aggregation phenomenon is not obvious. The structure of worm-like carbon nanospheres has some defects with graphitization degree ID/IG = 0.8. About the formation mechanism of worm-like carbon nanospheres is explained accordingly in the existing cases.

Although copper is essential for various functions in the human body, excessive intake can damage the nervous and immune systems. In this study, a new fluorescent covalent organic framework probe (DP-TFPB COF) was first reported. Relying on the rational design, the synthesized DP-TFPB COF demonstrates a distinctive fluorescence enhancement effect upon different solvent induction, achieving a quantum yield of up to 20.5 %. Then, a covalent organic framework-based ratiometric fluorescent system was developed, incorporating blue-emitting carbon dots to leverage the fluorescence energy transfer effect. Blue-emitting carbon dots served as the reference signal, while the DP-TFPB COF acted as the response unit, enabling successful quantitative detection of Cu 2+ . The mechanism study demonstrated that fluorescence quenching occurs through an electron transfer process, wherein the covalent organic framework serves as the electron donor and Cu 2+ functions as the electron acceptor. The developed method demonstrated excellent linearity for Cu 2+ within the concentration range of 0.5 to 200 μM, accompanied by a detection limit of 0.38 μM. The robust recognition capabilities exhibited significant effectiveness in the Cu 2+ analysis within herbal plants. The results correspond closely with those obtained using inductively coupled plasma mass spectrometry, thereby emphasizing its potential applicability in real samples with complex matrix.

Chalcopyrite and galena are significant sulfide minerals found in copper-lead (Cu-Pb) ores, drawing attention to environmentally friendly separation techniques in mineral processing . This research explored the use of calcium lignosulfonate (CLS) as a depressant to achieve efficient separation of chalcopyrite from galena under weakly alkaline conditions (pH=8–10). The adsorption behavior of CLS was analyzed using Fourier transform infrared spectroscopy (FT-IR), ultraviolet-visible spectroscopy (UV–vis), zeta potential measurements, and time-of-flight secondary ion mass spectrometry (ToF-SIMS). The findings revealed that CLS selectively adsorbed onto the galena surface, inhibiting the interaction between xanthate and galena. Furthermore, the results of X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) calculations indicated that CLS chemisorbed onto the galena surface through bonding between oxygen atoms in the sulfonic acid group and lead atoms, and the process occurred spontaneously. This selective adsorption significantly increased the hydrophobicity of the galena surface, enabling chromium-free separation of chalcopyrite and galena.

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.

Maintaining rheological stability of high-density water-based drilling fluids (WDFs) under high temperature conditions remains a formidable challenge for deep-well drilling operations. In this study, a zwitterionic polymer thinner (ZPT-3) was synthesized and systematically evaluated in both weighted mud (WM) and weighted polymer mud (WPM) systems through comprehensive rheological testing. Total organic carbon (TOC) analysis, focused beam reflectance measurement (FBRM), and optical microscopy were employed to investigate the mechanism of ZPT-3 in regulating the rheological behavior of high-density WDFs. ZPT-3 demonstrated exceptional thermal stability and thinning efficiency, yielding a viscosity reduction rate of 66.3% in complex WPM at 2 wt% after aging at 200 °C, significantly surpassing conventional commercial thinners (XY27 and SF260). To facilitate practical engineering applications, a multi-output machine learning (ML) model was developed to accurately predict rheological parameters of WM systems under varying additive concentrations and aging temperatures. These findings highlight ZPT-3 as a promising and robust thinner for high-density WDFs, with the ML predictive model providing a reliable digital assistant for the design and optimization of drilling fluid formulations.

TiO 2 nanosheets with rutile as the principle crystalline phase were prepared through the in-situ electrochemical oxidation of Ti 3 C 2 T x nanosheets. • Electrochemical transformation method exhibits higher efficiency in inducing the anatase-to-rutile phase transition than the conventional method of high-temperature heating. • Our study elucidates the mechanism underlying the structural evolution and phase transition in TiO 2 nanosheets from a thermodynamic perspective, offering valuable insights for the rational design of biosensing platforms towards biomolecules. Two-dimensional TiO 2 nanosheets (NS) enable efficient stabilization of aptamers and enhanced electron transfer on electrode surface for electrochemical biosensing applications. However, the effect of morphology and crystalline phase of TiO 2 NS on its detection performance towards biomolecules are unclear. Meanwhile, the mechanism underlying the structural evolution and anatase-to-rutile phase transition in TiO 2 NS via electrochemical transformation remains elusive. Thus, TiO 2 NS with rutile as the principal crystalline phase were prepared through the in-situ electrochemical oxidation of Ti 3 C 2 T x NS, offering a more accessible and sustainable alternative method compared to previously reported approaches. Density functional theory simulations demonstrated that electrochemical transformation method minimizes the phase transition energy difference and accelerates the phase transition. TiO 2 NS-based electrodes presented a low detection limit of 10.2 nM towards UA with sensitivity as 1.924 μA . cm –2. μM –1 (0.03–0.3 μM) and linear range from 0.03–0.3 and 0.03–300 μM, and achieved acceptable stability, interference resistance, temperature adaptability and feasibility in urine sample analysis. Our approach exhibits higher efficiency in inducing the anatase-to-rutile phase transition than the conventional method of high-temperature heating. Thus, our study elucidates the mechanism underlying the structural evolution and phase transition in TiO 2 NS from a thermodynamic perspective, offering valuable insights for the rational design of biosensing platforms towards biomolecules. TiO 2 nanosheets (NS) was in-situ fabricated and grown on the surface of Ti 3 C 2 T x NS controllably via the electrochemical oxidation of Ti 3 C 2 T x NS in the electrochemical reactor, as shown in Figure a. Extending the oxidation time leads to a monotonic increase in the surface coverage of TiO 2 nanoparticles (NP) until full coverage is achieved. Our synthesized TiO 2 NS exhibits superior electrochemical performance, owing to their increased surface-to-volume ration, shorter ion diffusivity paths, faster electron transferring and efficient immobilization of aptamers. Density functional theory simulations demonstrated that electrochemical transformation method minimizes the phase transition energy difference and accelerates the phase transition (Figure b). Our approach exhibits higher efficiency in inducing the anatase-to-rutile phase transition than the conventional method of high-temperature heating.

TAMOLL selectively adsorbed on the surface of calcite. • Using TAMOLL can effectively separate cassiterite from calcite. • The S-O - and S=O groups in TAMOLL chemically interacted with the Ca sites on calcite. The flotation separation of cassiterite from calcite has long been a challenge. In this study, the eco-friendly depressant sodium poly(naphthaleneformaldehyde sulfonate) (TAMOLL) was employed. Single-mineral tests demonstrated that TAMOLL strongly depressed calcite while barely affecting cassiterite. In the artificially mixed mineral system, a cassiterite concentrate grading 66.69% with a recovery of 86.59% was obtained at 16 mg/L TAMOLL. Multi-technique characterization, including contact angle, zeta potential, FTIR, XPS, and ToF-SIMS, combined with DFT calculations, systematically elucidated the selective depression mechanism. The sulfonate groups (−SO 3 - ) of TAMOLL coordinate with Ca sites on calcite via S-O - and S=O bonds, accompanied by pronounced electron transfer and orbital hybridization, forming stable S-O-Ca bonds. This leads to a dense, hydrophilic film on calcite, whereas TAMOLL adsorption on cassiterite is negligible, substantially widening the floatability difference. Consequently, cassiterite can be effectively floated by the subsequent NaOL collector. The strong chemisorption between TAMOLL and calcite is therefore the core mechanism, endowing TAMOLL with outstanding selective depression performance in cassiterite-calcite separation.

Characterizing exercise-induced fatigue is challenging due to difficulties in monitoring biochemical and electrophysiological signals consistently. While wearable sensors able to monitor both signals are available, they struggle to maintain stable signal acquisition across exercise-rest scenarios because of significant sweat variation. Here we describe the development of a system, FatigueVisual, combining an adaptive sweat-regulating hybrid electronic textile (e-ASRHT) patch with artificial intelligence (AI) analytics to improve fatigue management. The key innovation lies in the precise regulation of the breakthrough pressure of micropores in fabric electrodes and sweat-excreting areas, allowing for accurate sweat management. This design enables efficient enrichment at an ultralow sweat rate (5.0×10 −4 ml cm −2 min −1 ) while rapidly transporting excess sweat at a rate 2533 times the human physiological limit, ensuring stable chemical-electrophysiological sensing from exercise to rest. A cloud-connected AI model, trained on over 200,000 time-resolved observations collected from 10 participants, recognizes six fatigue-related states and provides personalized exercise management via a mobile app. Validation in three participants showed 87.3% agreement with clinical assessments. The system reduced exercise fatigue by 51.8% and accelerated recovery by 48 h compared with the control group. In practice, FatigueVisual may enable intelligent sports health management.

A chloramphenicol (CAP) electrochemical sensor based on zinc tungstate and maghemite nanocomposites (ZnWO 4 /γ-Fe 2 O 3 ) is proposed. First, ZnWO 4 and γ-Fe 2 O 3 nanomaterials were synthesized using a hydrothermal synthesis method, then compositely modified onto glassy carbon electrodes to construct electrochemical sensors for measuring CAP. Under optimal conditions, the ZnWO 4 /γ-Fe 2 O 3 -modified electrode exhibits a stronger reduction peak current for CAP detection than the single-component electrode and demonstrates better electrocatalytic activity. The results demonstrate that ZnWO 4 /γ-Fe 2 O 3 /GCE exhibits a linear detection range of 8–1000 μM and a detection limit of 1.04 μM, demonstrating good selectivity in the presence of different interferers, as well as outstanding stability and reproducibility. ZnWO 4 /γ-Fe 2 O 3 /GCE was used to detect of CAP in milk samples, yielding satisfactory results.

The development of robust biomimetic interfaces remains challenging due to the inherent instability of native cell membranes when integrated into functional devices. Herein, we reported a bio-based functional composite in which a chitosan-derived conductive hydrogel served as a multifunctional matrix to achieve unprecedented stabilization of red blood cell membranes (RBCMs). Leveraging the three-dimensional polycationic network and abundant amino groups of this natural polysaccharide, the hydrogel electrostatically anchored RBCMs while preserving their native fluidity and membrane-bound acetylcholinesterase conformation-overcoming a long-standing bottleneck in biomembrane-based material engineering. Integration of carboxylated multi-walled carbon nanotubes endowed the composite with efficient electron transfer capability without compromising biocompatibility. The resulting biomimetic interface retained 85.8% of its initial electrochemical response after 7 days of continuous operation and enabled sensitive detection of organophosphate pesticides in real agricultural samples (apples, oranges, and tomatoes). This work established chitosan hydrogel as a versatile bio-based platform for constructing stable biomembrane composites, expanding the application scope of natural polysaccharides in functional material design for environmental monitoring.

Paper-based analytical devices (PADs) have revolutionized environmental monitoring, food safety and disease diagnosis due to their inherent portability, simplicity, and cost-efficiency. Among these, distance-based PADs enable instrument-free quantitative detection by translating target concentration into measurable flow distance. Stimuli-responsive hydrogels, whose viscosity can be altered by target-triggered sol-gel transitions, are widely used in distance-based PADs, among which click-chemistry hydrogels stand out by virtue of their efficient and stable covalent bonding. Such stable covalent networks provide click hydrogels with strong anti-swelling and anti-degradation properties, crucial for reliable performance in on-site environments. In this study, we present a novel distance-based PAD approach that integrates target-induced click hydrogels, establishing a highly stable, versatile, and sensitive platform for multi-analyte detection. This innovative PAD makes use of copper-catalyzed azide-alkyne cycloaddition click chemistry to craft hydrogels from polyethylene glycol derivatives. Notably, specific target analytes like Cu²⁺, ascorbic acid, alkaline phosphatase, and pyrophosphate finely modulate the hydrogel crosslinking degree, causing noticeable changes in its viscosity. These viscosity variations are then translated into measurable flow distances on pH test papers, providing a direct and quantitative visual readout without the need for complex instrumentation or extensive operation. The entire detection process, from sample loading to result readout, can be accomplished within approximately 5 min, demonstrating the rapid analysis capability of this approach. This work offers stable, rapid, sensitive, and cost-effective multi-target detection, significantly advancing instrument-free PAD technology and expanding the scope of versatile analyte detection.
