The rapid and efficient separation of nanoscale targets in liquid matrices presents a critical yet formidable challenge. Polyamide (PA) membranes, while recognized as the benchmark for industrial-scale nanoscale separation, face ongoing limitations in performance optimization. Although advances in nanomaterials have enabled breakthroughs in PA membrane performance, scalable production remains hindered by integration challenges. Here, we present a scalable strategy to fabricate ultra-thin (<10 nm) nanofiltration membranes by constructing a layered double hydroxide (LDH) nanoplate-enhanced piperazine (PIP) intermediate layer via interfacial polymerization (IP) with trimesoyl chloride. Hydrogen-bond networks between PIP and LDH, combined with ordered water structures induced by LDH hydroxyl groups, restricted PIP diffusion, thus yielding ultrathin membranes with high ionization. Moreover, the rough LDH intermediate layer promoted a rougher membrane surface, enhancing the effective filtration area and permeability. The optimized membranes achieved a pure water permeance of 89.6 ± 3.5 L m −2 h −1 bar −1 and a Na 2 SO 4 rejection rate of 95.7%, achieving one of the best-reported levels. Leveraging the accessibility of LDH colloids and the scalable fabrication process, this strategy enables the production of large-area membranes via spraying and IP, making it highly promising for purifying and recovering antibiotics.

The development of eco-friendly time-dependent phosphorescent color (TDPC) materials faces a critical paradox: Boron oxide (B 2 O 3 ) derived from commercial boric acid (B 2 O 3 - CBA ) exhibits stable room-temperature phosphorescence (RTP) regardless of purity, while ultrapure synthetic analogs remain non-emissive. Here, this dilemma is resolved by engineering carbon dots (CDs) doped into B 2 O 3 - CBA at ultralow concentrations (10 ppb), achieving programmable TDPC through three breakthroughs. Synergistic host-guest confinement amplifies green RTP efficiency by an order of magnitude enhancement while activating yellow guest emission; Defect-mediated exciton transfer extends RTP lifetimes to 304 ms, doubling B 2 O 3 - CBA ; Time-resolved chromatic evolution (Δλ = 65 nm) emerges exclusively in doped systems, enabled by bifurcated decay kinetics from dual confinement mechanisms. The CDs@B 2 O 3 exhibits remarkable stability in harsh liquids, overcoming stability barriers for encryption applications. This ppb-level doping strategy circumvents purity debates while preserving host crystallinity—a critical advance toward scalable anti-counterfeiting tags and bioimaging probes with programmable temporal-color responses.

Sodium-ion battery (SIB), as a crucial supplement to lithium-ion battery (LIB), have shown significant application value in the field of large-scale energy storage and electric vehicles. However, the alkali erosion problem triggered by its cathode materials during high-temperature synthesis will become a key bottleneck restricting its industrialization. In this study, we broke through the traditional passive protection strategy, and based on the deepening and expanding of established protocol of stable coexistence of alkali erosion products and their corresponding homologous alkali metal compounds (EPAMC), we innovatively designed and verified the functionalization application of Na 4 Ca 3 (AlO 2 ) 10 (N 2 C 3 A 5 ) in the synthesis to SIB cathode material. The results show that under the simulated industrial calcination conditions (850 °C/12 h), the erosion depth of N 2 C 3 A 5 is only 56.33 ± 23.82 μm, which is significantly better than that of the traditional material system, and the erosion mechanism is recognized as “melt-penetration”. Compared with the control group, the apparent porosity of the experimental group decreased by 20.08 ± 2.57 %, and the residual strength retention after three cycles increased by 10.11 ± 0.05 %. It is noteworthy that this study provides new ideas for the first time to crack the alkali erosion challenge from the perspective of elemental composition and physical phase design, accelerates the exploration of novel alkali erosion-resistant materials, and is of great guiding significance for advancing the engineering application of energy storage materials .

A general approach is presented for synthesis of multicolored gold nanoparticles (GNPs) by Au(I)-mediated generation of interlocking rings in proteins and antibiotics. The Au(I) ions are shuttled from proteins to antibiotics, and this causes the formation of interlocking rings. The multicolored GNPs of different sizes were synthesized in the rings by using the rapid nucleation method. To take the unique colors of GNPs, a functional array was designed for the colorimetric determination and discrimination of antibiotics, specifically of amoxicillin, chlortetracycline, erythromycin, spiramycin, neomycin, thiamphenicol, gentamycin and lincomycin. The method is based on the “three color” (RGB) principle. The color response patterns are characteristic for each antibiotic and can be quantitatively differentiated by statistical techniques. The limits of detection (LOD, at S/ N = 3) for spiramycin (Sp) have been calculated to be 0.18 μM and 0.10 μM in water and milk, respectively. The good linear range (from 0.3 to 3.5 μM) has been used for the quantitative assay of Sp in a certified reference material.
Schematic presentation of gold nanoparticles (GNPs) synthesis via formation of interlocking rings in protein and antibiotics. The Au(I) ions mediate protein and antibiotics to be interlocking rings, which are quickly fixed via microwave reaction. The GNPs are synthesized and assembled in the rings.

SnO 2 is considered as an ideal substitute for graphite anode in lithium ion batteries since it has a four-fold theoretical capacity and low discharge potential. However, the poor transformation from Sn/Li 2 O to SnO 2 due to sluggish kinetic results in a low initial Coulombic efficiency (ICE) of only 52.4%. At the same time, the intrinsically low ionic/electronic conductivity and high volume swings during charge/discharge processes seriously limit its long-term stability and high-rate performance. Different from traditional strategies, nanotechnology and composite, this work prepares sub-10 nm SnO 2 /Fe 3 O 4 /graphene nanosheets with controllable Fe/Sn atomic ratios through a hydrothermal method to study the nanocatalytic effect of Fe on improving the ICE. The component, structure and lithium storage performance of the samples, with varied Sn/Fe ratios, are systematically investigated. The sample with Sn/Fe of 1.31 shows a high ICE of 70.9% (considering the negative effect of huge solid/electrolyte interface films, this value is quite high) and an outstanding reversible capacity of 1048 mA h g −1 after 800 cycles at the current density of 200 mA g −1 . The valence states of Sn and Fe before and after cycling are analyzed by X-ray photoelectron spectroscopy. Our findings offer new evidence for electrochemical catalytic conversion mechanism for lithium storage and highlight opportunities to boost the energy storage capability of the fourth main group compounds.

Hydrogel-enabled skin bioelectronics that can continuously monitor health for extended periods is crucial for early disease detection and treatment. However, it is challenging to engineer ultrathin gas-permeable hydrogel sensors that can self-adhere to the human skin for long-term daily use (>1 week). Here, we present a ~10-micrometer-thick polyurethane nanomesh–reinforced gas-permeable hydrogel sensor that can self-adhere to the human skin for continuous and high-quality electrophysiological monitoring for 8 days under daily life conditions. This research involves two key steps: (i) material design by gelatin-based thermal-dependent phase change hydrogels and (ii) robust thinness geometry achieved through nanomesh reinforcement. The resulting ultrathin hydrogels exhibit a thickness of ~10 micrometers with superior mechanical robustness, high skin adhesion, gas permeability, and anti-drying performance. To highlight the potential applications in early disease detection and treatment that leverage the collective features, we demonstrate the use of ultrathin gas-permeable hydrogels for long-term, continuous high-precision electrophysiological monitoring under daily life conditions up to 8 days.

The ultra-small Lu6O5F8: 1%Er3+/10%Yb3+ up-conversion nanoparticles (UCNPs) were prepared via a co-precipitation method and used for detection of metal ions . Compared with other metal ions (Na+, Mg2+, Al3+, Fe2+, Co2+, Cd2+, etc), the up-conversion luminescence (UCL) intensity was reduced by 90% in the presence of Cu2+. Moreover, Strong quenching (65%) of the emission was observed upon the addition of Cu2+ in the concentration range of 0–10 μM. Meanwhile, the Cu2+ luminescence quenching mechanism was studied in detail. Under the 980 nm (1550 nm) excitation, the red UCL intensity of (Lu0.79Y0.1)6O5F8: 1%Er3+/10%Yb3+ and (Lu0.85Gd0.04)6O5F8: 1%Er3+/10%Yb3+ UCNPs enhanced about 4.67 (19.3) times and 3.95 (8.89) times than that of Y3+, Gd3+-absent samples, respectively. The temperature-sensing effect of Lu6O5F8: 1%Er3+/10%Yb3+ was also studied in detail, including not only this thermally coupled level (Er3+ 2H11/2, 4S3/2), but also the non-thermally coupled levels (Er3+ 2H11/2, 4F7/2). The absolute (S a ) and relative sensitivity (S r ) of Lu6O5F8: 1%Er3+/10%Yb3+ based on non-thermally coupled levels is much higher than that based on thermally coupled levels in the 293–473 K range. The maximum S a and S r is 0.087 and 0.0185 K −1 at 293 K. These meaningful results indicate that Lu6O5F8: 1%Er3+/10%Yb3+ materials have broad prospects in UCL multifunctional applications.

BACKGROUND Many natural products confer health benefits against diverse diseases through their antioxidant activities. Carbon tetrachloride (CCl 4 ) is often used in animal experiments to study the effects of substances on liver injury and the related mechanisms of action, among which oxidative stress is a major pathogenic factor. AIM To compare antioxidant and hepatoprotective activities of ten herbs and identify and quantify phytochemicals for the one with strongest hepatoprotection. METHODS The antioxidant activity of ten medicinal herbs was determined by both ferric-reducing antioxidant power and Trolox equivalent antioxidant capacity assays. The total phenolic and flavonoid contents were determined by Folin–Ciocalteu method and aluminum chloride colorimetry, respectively. Their effects on CCl 4 -induced oxidative liver injury were evaluated and compared in a mouse model by administrating each water extract (0.15 g/mL, 10 mL/kg) once per day for seven consecutive days and a dose of CCl 4 solution in olive oil (8%, v/v, 10 mL/kg). The herb with the strongest hepatoprotective performance was analyzed for the detailed bioactive components by using high-performance liquid chromatography-electrospray ionization source-ion trap tandem mass spectrometry. RESULTS The results revealed that all tested herbs attenuated CCl 4 -induced oxidative liver injury; each resulted in significant decreases in levels of serum alanine transaminase, aspartate transaminase, alkaline phosphatase, and triacylglycerols. In addition, most herbs restored hepatic superoxide dismutase and catalase activities, glutathione levels, and reduced malondialdehyde levels. Sanguisorba officinalis ( S. officinalis ) L., Coptis chinensis Franch., and Pueraria lobata (Willd.) Ohwi root were the three most effective herbs, and S. officinalis L. exhibited the strongest hepatoprotective effect. Nine active components were identified in S. officinalis L. Gallic acid and (+)-catechin were quantified (7.86 ± 0.45 mg/g and 8.19 ± 0.57 mg/g dried weight, respectively). Furthermore, the tested herbs displayed a range of in vitro antioxidant activities proportional to their phenolic content; the strongest activities were also found for S. officinalis L. CONCLUSION This study is of value to assist the selection of more effective natural products for direct consumption and the development of nutraceuticals or therapeutics to manage oxidative stress-related diseases.

Optical waveguide (OWG) sensors are widely used in gas detection, and sensitive materials are the key factors affecting sensor performance. Herein, we report on a 5,10,15,20-tetrakis-(4-methoxyphenyl) porphyrin (TMP) deposited optical wave guide (OWG) sensor. The porphyrin solutions with different acidity were deposited on a K + -ion exchanged glass OWG surface by spin coating, to fabricate porphyrin film-coated OWG gas sensing devices. The effects of pH values of the porphyrin solution used to prepare the sensitive film on the sensing properties of these devices were investigated. The gas sensitive performances of these devices in response to analytes were compared. Among them, the sensing devices fabricated using original and acidic solutions of porphyrin exhibited significant responses to sulfide gases and ethanediamine, respectively. The sensing device prepared using an acidic solution has a good response to ethanediamine gas (response and recovery times of the sensor for 1 ppm of EDA (ΔI = 48) are 13 and 38 s, respectively). The RSD of the output light intensity is ±2.84, the signal to noise ratio (S/N) is 5.6. The device prepared using the original solution has an excellent response to sulfide gases (H 2 S, SO 2 ), and can detect low concentration levels (ppm) of sulfide gases. These sensing devices thus have the potential to be used in food quality testing and environmental monitoring.

An imidazolium-based ionic liquid (IL) was employed and modified by sodium lignosulfonate (LnNa) to synthesize hierarchical ETS-10 zeolite with porous structure, morphology and surface properties effectively adjusted. The template and structure-directing effects of both IL and LnNa proved to be well maintained after modification. And more importantly, the unique molecular recognition of LnNa was preserved well, while the aggressiveness of LnNa implementing through interaction with other inorganic species can be efficiently suppressed. This led to the formation of hierarchical ETS-10 zeolite with not only high crystallinity and structure integrity but also enhanced catalytic performance in aqueous-phase biomass conversion. Thus, for guaiacol hydrodeoxygenation, a notable conversion (92.8%) and cyclohexane yield (89.7%) can be acquired. This remarkable catalytic reactivity should be owing to its distinguished analogous molecular recognition pattern, promoted crystallinity, modified morphology and porous structure, and what’s more, the strengthened acid property.

The partial substitution of Cu+ with Ag+ into the host lattice of Cu2ZnSn(S,Se)4 thin films can reduce the open-circuit voltage deficit (Voc,deficit) of Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. In this paper, elemental Cu, Ag, Zn, Sn, S, and Se powders were dissolved in solvent mixture of 1,2-ethanedithiol (edtH2) and 1,2-ethylenediamine (en) and used for the formation of (Cu1–xAgx)2ZnSn(S,Se)4 (CAZTSSe) thin films with different Ag/(Ag + Cu) ratios. The key feature of this approach is that the impurity atoms can be absolutely excluded. Further results indicate that the variations of grain size, band gap, and depletion width of the CAZTSSe layer are generally determined by Ag substitution content. Benefiting from the Voc enhancement (∼50 mV), the power conversion efficiency is successfully increased from 7.39% (x = 0) to 10.36% (x = 3%), which is the highest efficiency of Ag substituted devices so far.

In the present work, two LiBH4 based hydrogen storage composites, namely, 3LiBH4/graphene and 3LiBH4/graphene–10 wt% CeF3, were prepared through ball milling and their hydrogen sorption behaviors were investigated. It was shown that the dehydrogenation kinetics of 3LiBH4/graphene was improved by doping 10 wt% CeF3, which was attributed to the formation of CeB6. The rehydrogenation of the 3LiBH4/graphene composite could be achieved under 440 °C with 3.3 MPa hydrogen pressure and the hydrogen absorption capacity reached 7.40 wt% to LiBH4 after 10 h. Further addition of CeF3 did not improve the rehydrogenation kinetics but reduced the absorption capacity. SEM observations suggested that LiBH4 was confined in a graphene wrapper after rehydrogenation, forming “graphene capsules” that helped the regeneration of LiBH4.
