Generally, Fe(II) has an efficiently catalytic activity toward peroxymonosulfate (PMS), but the slow conversion of Fe(III) to Fe(II) and production of iron sludge impede the practical application of Fe(II)/PMS system. In this work, ascorbic acid (AA), a complexing agent and reductant, was introduced to Fe(III)/PMS process to facilitate the Fe(III) reduction. The decoloration of rhodamine B (RhB) was obviously enhanced in Fe(III)/PMS process with the addition of AA. Fe(III)-AA complex was firstly generated in Fe(III)/AA/PMS process via the complexation and then was reduced to Fe(II), which could catalyze PMS to yield oxidative species. Fe(IV), sulfate radical (SO 4 •− ) and hydroxyl radical ( • OH) were the working oxidants for RhB decoloration in this system, and SO 4 •− played a major role. Increasing Fe(III), AA or PMS dosage was beneficial to RhB decoloration, but their excessive concentration would hinder RhB decoloration. The existence of HCO 3 − , SO 4 2− or FA in this system showed an inhibition effect on RhB decoloration, while a facilitation effect was obtained when the high concentration of Cl − was present. This research offers a way to improve PMS activation by Fe(III) and a technology for eliminating the refractory organic pollutants from the contaminated water.

The increasing demand for potash has led to the increased use of 4-dodecyl morpholine (DMP), an important froth flotation agent for the extraction for potash extraction by “reverse flotation-cold crystallization”. As it is not easy to be stable and decompose in its natural state, it has seriously endangered the environment of salt lakes and the development of salt lake resources. The development of a safe and harmless catalytic system to accomplish the degradation and removal of DMP is urgent. Herein, A Cu 2 O/SnO 2 /PDA (CSP) nanoparticle with a synergistic effect of photocatalysis and Fenton-like catalysis was developed, and the CSP had a good photothermal conversion efficiency. Under 808 nm NIR irradiation, not only the catalyst activity was enhanced, but also the complexation rate of electron-hole pairs was reduced, which effectively increased the degradation efficiency of DMP (an increase of about 31.56 %). In addition, by analyzing the degradation products of DMP, the possible pathways of the DMP degradation process were proposed and, at the same time, the degradation catalytic system we used was proved to be safe and harmless. A new pathway is provided for the degradation and removal of DMP in the salt lake environment.

In recent years, with the development of electric vehicles and electric vessels, the issues of battery thermal safety have garnered significant attention. Composite phase-change materials (CPCMs) hold great potential as passive cooling systems in battery thermal management systems (BTMS), but their high flammability remains an unresolved challenge. This study successfully developed a flexible composite phase-change material, CPCM/P-CSF@rGO, by encapsulating a eutectic phase-change material composed of mannitol and galactitol in a three-dimensional hydrogen-bonded network, self-polymerised by phosphated corn straw cellulose (P-CSF) and reduced graphene oxide (rGO). The study demonstrates that the strong hydrogen bonding network formed between the phosphate groups introduced by phosphoric acid modification and rGO constructs highly efficient thermal conduction pathways, achieving a thermal conductivity of 1.039 W/(m•K) and significantly accelerating thermal response rates. Simultaneously, the incorporation of the P-CSF@rGO framework endows the material with excellent flexibility and shape stability. Due to the in-situ flame-retardant modification of the framework, the phase-change material maintains a high latent heat of phase-change (194.7 J/g) and achieves superior flame retardancy through gas-phase and condensation-phase mechanisms. It exhibits a limiting oxygen index of up to 30.64% and rapidly extinguishes itself when exposed to open flame in atmospheric conditions. Thus, the flexible composite phase-change material (CPCM/P-CSF@rGO) supported by a phosphorylated cellulose framework emerges as a promising candidate for ensuring safety and high performance in thermal management applications.

Binary colloidosomes with periodic cubic symmetry are fabricated from anisotropic gold nanocubes and isotropic gold nanospheres. • The spatial arrangement of AuNPs within the colloidosomes is predominantly governed by entropic effects between the two components. • This study provides a general and efficient route to precisely engineer of binary colloidosomes from geometrically distinct nanocrystals. Binary colloidosomes constructed from polymer-grafted inorganic nanocrystals have recently garnered significant attention for their potential in constructing multifunctional materials. However, the fabrication of well-defined binary colloidosomes with tailored internal architectures using geometrically distinct nanoparticles remains challenging. In this study, we demonstrate the preparation of binary colloidosomes with periodic cubic symmetry via emulsion interfacial co-assembly of polystyrene-tethered anisotropic gold nanocubes (AuNCs@PS) and isotropic gold nanospheres (AuNPs@PS). The spatial distribution of AuNPs@PS within the resulting colloidosomes is predominantly governed by entropic effects between the two components, which are quantitatively characterized using the proposed effective size ratio parameter ( λ eff ). Furthermore, by tailoring the core size of AuNPs@PS and the molecular weight of the grafted polymer, the λ eff value and the resulting configuration of the colloidosomes can be precisely controlled. This strategy provides a versatile pathway for constructing binary colloidosomes with tailored internal structures, facilitating the rational design of advanced functional materials for applications in catalysis, optoelectronics, and photothermal therapy. Well-defined binary colloidosomes with periodic cubic symmetry self-assembled from anisotropic AuNCs@PS and isotropic AuNPs@PS building blocks are constructed through emulsion interface co-assembly strategy. The spatial distribution of AuNPs@PS within the resulting colloidosomes is predominantly governed by entropic effects between the two components.

Tissue trauma or chemical injury can compromise tissue integrity and trigger an inflammatory response, which can severely hinder the tissue repair process, particularly in patients with diabetes. Existing wound repair methods struggle to strike a balance between efficacy and cost. We develop a novel natural-based nano-cellulose membrane (LOBCC) by combining lignin-based carbon dots, modified cellulose nanocrystals, and a pure cellulose matrix. The low cost of the all-natural polymer matrix, combined with the introduction of antioxidant carbon dots and the antioxidant properties of cellulose nanocrystals, positions LOBCC as a viable alternative strategy for tissue repair.

The surface functional layer of biochar promotes lanthanum dispersion. • Lanthanum-loaded biochar adsorbed 63.5 mg P·g −1 of phosphate within 1 min. • Phosphate in the fixed-bed effluent kept below 0.2 mg P·L −1 . • Lanthanum raised phosphate selectivity over nitrate and sulfate by 14 and 32 times. • Molecular dynamics simulations show lanthanum boosting phosphate dehydration and diffusion. Metal-doped biochar is a promising phosphate adsorbent for mitigating phosphate-driven eutrophication and valorizing biomass, but its adsorption performance, selectivity and stability are strongly governed by the biochar-metal structure. Herein, the biochar was embedded into carbon nanofiber’ networks to construct a self-supporting biochar-carbon nanofiber framework (C-ACF). The C-ACF was first functionalized with an amine-rich HCCP-PEI polymer layer to obtain PCP@C-ACF, which was then used to anchor highly dispersed La species, yielding the performant La-loaded adsorbent PCP-La@C-ACF. Expectantly, PCP-La@C-ACF exhibited outstanding phosphate adsorption kinetics and selectivity, achieving phosphate uptake of 63.5 mg P·g −1 within 1 min (9.3-fold that of La(OH) 3 ) and an equilibrium capacity of 93.9 mg P·g −1 , along with broad pH tolerance and marked reusability. Under fixed-bed operation, PCP-La@C-ACF maintained the effluent phosphate concentration below 0.2 mg P·L −1 (removal rate > 99.4%). Owing to the loaded La species, markedly improved phosphate selectivity under high concentrations of Cl − , NO 3 – , and SO 4 2− was achieved, with selectivity coefficients against NO 3 – and SO 4 2− being 14- and 32-fold higher than La-free PCP@C-ACF. Molecular dynamics simulations rationalize that such dispersed La species enhance adsorption selectivity/rate by promoting phosphate dehydration and improving interfacial diffusion efficiency.

The core–shell FeNPs@Pt shows excellent catalytic activity and stability. • Selective detection via thiol–Michael addition without enzymes or aptamers. • The color development is rapid and convenient, taking only 150 s to complete. • The suppression–recovery mechanism amplifies the signal and enhances sensitivity. In this study, we propose an innovative Acrylamide (AA) detection platform based on platinum-coated magnetic iron nanoparticles (FeNPs@Pt). The introduction of a platinum shell not only preserves the intrinsic catalytic properties of FeNPs but also significantly enhances their structural stability and catalytic activity. Compared with traditional antibody–aptamer-based detection methods, this platform employs a thiol–Michael addition reaction combined with a nanocatalyst-mediated cascade colorimetric process. This approach overcomes key limitations of antibody–aptamer technologies, such as high cost and operational complexity, enabling rapid and low-cost detection of AA. The mechanism involves a specific Michael addition reaction between AA and 2,2′-(ethylenedioxy)diethanethiol (EDT), which mitigates the inhibitory effect of EDT on the catalytic activity of FeNPs@Pt. Subsequently, the addition of 3,3′-dimethylbenzidine (TMB) triggers a colorimetric reaction within 150 s, rendering the result visible to the naked eye. This sensing platform exhibits a linear response over the range of 1–200 μM, with a detection limit as low as 0.63 μM. Notably, the FeNPs@Pt–EDT–TMB-based colorimetric detection platform not only provides an efficient and low-cost method for acrylamide detection but also offers an innovative solution for on-site food safety monitoring, demonstrating significant application potential.

Artificial visual systems require hardware that can directly couple light sensing with information storage and processing. Here, we fabricate an egg-albumen/reduced-graphene-oxide (EA/rGO)-based photoelectric synaptic memristor with reproducible bipolar resistive switching, an ON/OFF current ratio of 2.21 × 10 5 , retention exceeding 10 4 s, and 100-cycle endurance. Benefiting from the incorporation of rGO, the device exhibits improved switching uniformity and supports eight distinct conductance states for multilevel data storage. Under photoelectric co-stimulation, the memristor emulates key synaptic functions, including paired-pulse facilitation and potentiation/depression behavior, and further implements AND/OR logic operations. In addition, a 5 × 5 device array reproduces an “E” pattern through spatially selective optical-state modulation and cell-by-cell readout, demonstrating array-level optical-pattern sensing and nonvolatile state storage. These results establish the EA/rGO device as a promising biomaterial platform for photoresponsive sensing–memory integration and neuromorphic electronics.

LC sensing platform based on WGM laser is developed for the AD-related biomarker Aβ42 detection. • The sensor sensitivity is approximately 0.003 nm/pg/mL, and the LOD is 3 pg/mL. • RNA aptamer is used as recognition probes to enhance the specificity of the biosensing platform. • The combination of RNA aptamer and Aβ42 causes RI changes, resulting in WGM spectral shifts. • The structure design provides an ideal sensing platform for detecting biomedical samples. Alzheimer's disease (AD) is an irreversible and progressively worsening neurodegenerative disorder. Amyloid beta (Aβ42) plays a crucial role in the early diagnosis of this disease. However, the concentration of Aβ42 in the blood is extremely low, which poses a challenge for Aβ42 detection. Herein, a liquid crystal (LC) biosensing platform based on whispering gallery mode (WGM) laser was developed for rapid and real-time monitoring of the AD-related biomarker Aβ42. The LC microcavities were functionally modified using cetyltrimethyl ammonium bromide (CTAB) and RNA aptamers. Based on this, the quantitative monitoring mechanism of Aβ42 was analyzed, stemming from the interaction between the negatively charged RNA aptamer and CTAB, leading to the reorientation of LC molecules. This alters the refractive index distribution within the microcavity, thereby enabling the shift of the WGM spectrum. The dynamic changes of molecular orientation in the LC microcavity were monitored by polarization optical microscopy and spectral analysis. The experimental results showed that the total shifts in the resonance spectrum were directly proportional to the concentration of Aβ42 within the range of 0–1000 pg/mL. The sensitivity of the sensor is 0.003 nm/pg/mL. The experiment further confirmed the practicability of this sensor in the mouse serum. The sensor is inexpensive, easy to manufacture and fast and it is potentially useful for AD-related biomarker screening after further validation.

While selenium (Se) exposure in endemic poisoning areas has been extensively investigated, its co-occurrence with other heavy metals and the implications for integrated environmental health management remain insufficiently addressed. This study developed a risk-based dietary optimization framework by assessing the concentrations, spatial distribution, and probabilistic health risks of 24 elements in four staple crops (rice, maize, potato, and sweet potato) collected from Shuang’an Township, a recognized human Se poisoning area in China. Results revealed widespread exceedances of maximum limits (ML) for Cd, Se, Cr, Zn, and Cu, with Cd (65.8% of samples exceeded ML; maximum exceedance factor = 145.7) and Se (52.1% exceeded ML; maximum exceedance factor = 56.3) posing the most significant risks. Potatoes exhibited the highest contamination levels among all crops. Monte Carlo simulations demonstrated that dietary composition substantially influenced cumulative health risks, with total target hazard quotient (TTHQ) values ranging from 9 to 24 under different consumption scenarios. Potato intake showed a significant positive correlation with TTHQ (r = 0.67, p < 0.05), whereas sweet potato intake showed a significant negative correlation (r = –0.71, p < 0.05), indicating sweet potato as a comparatively lower-risk alternative. The proposed probabilistic framework provides useful information for dietary risk management in Se-endemic areas. These findings highlight the necessity of shifting from a Se-centered management perspective toward integrated multi-metal risk control strategies in Se-endemic areas.

Size-controllable Cu 2 O nanocubes grow in-situ on AMXene via Oswald-ripening mechanism. • Cu 2 O induces MXene amorphization, generating edge-ligand unsaturated sites for HER. • The electron-rich Cu + boosts orbital hybridization for selective glycerol oxidation. • The catalyst requires only 1.31 V electrolyzer voltage with stability exceeding 150 h. Glycerol oxidation reaction (GOR) is a mild, sustainable pathway with great potential for producing high-value chemicals such as formic acid (FA). Integrating GOR with hydrogen evolution reaction (HER) circumvents the high energy barrier of anodic oxygen evolution in traditional water splitting. However, achieving selective C C bond cleavage in glycerol-to-FA conversion remains a major technical and scientific challenge. Here, via the Ostwald ripening mechanism, size-tunable cuprous oxide nanocubes are in-situ grown on amorphous MXene (Cu 2 O/AMXene), creating well-defined dual active sites with clear functional division: electron-rich Cu + for GOR and Ti sites for HER. The optimized Cu 2 O-0/AMXene (28 nm Cu 2 O) delivers a HER overpotential of 32 mV at 10 mA cm −2 , a GOR potential of 1.13 V at 10 mA cm −2 , and a full electrolyzer voltage of 1.31 V, while maintaining excellent catalytic efficiency after 150 h of continuous operation. Cu 2 O growth induces MXene amorphization, generating edge ligand-unsaturated Ti sites that enhance water dissociation for proton supply, while Ti 4+ promotes hydrogen spillover to transfer protons to Ti 3+ for efficient HER. Electron-rich Cu + forms asymmetric Ti-O-Cu interactions via electron donation from AMXene, enhancing orbital overlap with p orbitals of glycerol oxygen atoms for GOR. This electron-rich environment inhibits Cu + oxidation to Cu 2+ at high anodic potentials, stabilizing the active s - p hybrid configuration. This work also highlights the critical role of O-functional groups on AMXene and lattice O atoms in Cu 2 O for strengthening metal-support interactions.

Five correlatable stone coal layers formed in the Ediacaran-early Cambrian succession. • Critical metals display pronounced spatial-stratigraphic heterogeneity. • Layer 3 hosts anomalous Se-Mo and significant Cd-V enrichment. • Metal enrichment was dominated by hydrothermal fluids and enhanced by algal activity. • Ga, V, Mo, and Cd indicate substantial critical-metal resource potential. The Qinling-Daba Mountains represent one of the major stone coal bearing areas in China, where multiple stone-coal layers occur within the Ediacaran-early Cambrian strata. These stone coal are commonly enriched in critical metals; however, their spatial and stratigraphic enrichment patterns remain poorly understood. In this study, we investigated the enrichment characteristics of 14 critical metals across three major belts (southern, central, and north) in the Qinling-Daba stone coal area. The results show that the Ediacaran-early Cambrian strata contain five regionally correlatable stone coal layers, three within the Ediacaran and two within the lower Cambrian. Critical metal enrichment exhibits pronounced spatial and stratigraphic pattern: the southern belt displays the strongest enrichment, whereas layer 3 ( Z 2 3 ) consistently hosts the highest enrichment of critical metals. Within this layer, Se and Mo reach anomalous enrichment levels (EF max > 100), and Cd and V are significantly enriched (EF max > 10) across all three belts. Four critical metals, Ga, V, Mo, and Cd, show significant mining potential. Inorganic and organic geochemical evidence indicates that hydrothermal input was the primary control on metal enrichment across the five layers, whereas the exceptionally high metal enrichment in layer 3 were further amplified by biogenic contributions, particularly from marine algae. These findings clarify the spatial and stratigraphic controls on critical metal enrichment in the Qinling–Daba stone coal area and provide new insights into hydrothermal–biological interactions and metalliferous sedimentation in Ediacaran-Cambrian basins.
