137 Cs and 131 I exhibit pronounced radiotoxicity, prolonged environmental persistence, and high mobility, posing dual threats to ecosystems and human health. The simultaneous removal of Cs + and I − using a single adsorbent is an area of growing research interest. In this study, a rationally designed dual-imprinted membrane (IPA-MC) was engineered via electrospinning and ion-imprinting technology for selective cesium and iodine adsorption. Crosslinking of zwitterionic polyethyleneimine-acrylic acid (PEI-AA) yielded hierarchical porous structures, which enhanced adsorption selectivity and capacity. Optimal adsorption performance occurred at pH 6.0, and its adsorption kinetics followed the pseudo-second-order model, indicating that chemical adsorption was the dominant mechanism mechanisms. IPA-MC maintained efficient and selective adsorption in the presence of interfering ions and demonstrated excellent regeneration capacity. Synergistic amino-carboxyl interactions enhanced adsorption for Cs + and I − , with particularly high efficiency for iodine removal. This work demonstrates an effective strategy for the selective extraction of nuclides using composites through multiple interactions. These composites show significant potential for radioactive wastewater treatment applications.

Energy-efficient windows are crucial for enhancing energy efficiency. However, developing novel window materials that simultaneously achieve high visible light transmittance, exceptional ultra-broadband near-infrared (NIR) shielding performance, neutral color appearance, long-term stability, cost-effectiveness, and sustainable production remains a formidable challenge. This study introduces a breakthrough material fulfilling all these requirements: ferrous ion-doped phosphosilicate glass (Fe 2+ -PSG), which emerges as a promising candidate for energy-efficient windows. Comprehensive characterization using UV–Vis-NIR transmittance/absorption spectroscopy and Raman spectroscopy reveals that Fe 2+ -PSG exhibits remarkable visible light transmittance of 83.7 ± 0.5%, a neutral color temperature of 6809 ± 53 K, and a high NIR shielding figure of merit of 1.80 ± 0.01. These exceptional properties primarily originate from the formation of colorless ferrous [FeO 6 ] units, influenced by phosphorus and cesium oxide incorporation. Moreover, Fe 2+ -PSG exhibits outstanding stability, retaining its optical performance for over 10 years under ambient conditions, and maintaining structural integrity after 24-hour immersion hot water (80 °C) and hot air (120 °C) exposures. These superior characteristics stem from unique structural modifications that modulate the crystal field splitting energy of Fe 2+ ions, enabling precise tuning of optical properties across the visible and NIR spectral ranges. Produced via a scalable, facile and low-cost melt-quenching process, Fe 2+ -PSG offers a feasible and sustainable solution for energy-efficient window fabrication. This innovation overcomes existing technological limitations and facilitates widespread practical applications.

Multilayer PVDF membrane with TiO₂/ZIF-8 and CS-SDAEM brush. • Superhydrophilic: water contact angle drops to 0° within 1.3 s. • Pure water flux 1440 L·m⁻²·h⁻¹ and dye rejection over 93%. • Synergy enables > 93% flux recovery after 10 cycles without cleaning. • Excellent stability against ultrasonication, abrasion, and harsh chemicals. Conventional polymer separation membranes suffer from severe fouling, limiting their efficiency in wastewater treatment. To address this issue, we develop a multilayer-modified PVDF membrane by integrating a TiO₂/ZIF-8 photocatalytic layer and a CS-SDAEM zwitterionic polymer brush. The TiO₂/ZIF-8 nanoparticles are deposited on the membrane surface, followed by crosslinking and grafting of CS-SDAEM, which forms a robust hydration layer and physically encapsulates the nanoparticles. The resulting membrane exhibits superhydrophilicity (water contact angle drops to 0° within 1.3 s) and achieves a pure water flux of 1440 L·m⁻²·h⁻¹ with over 93% dye rejection for various dyes. Owing to the synergistic adsorption, photocatalysis, and antifouling effects, the membrane shows excellent self-cleaning ability, maintaining a flux recovery rate > 93% after 10 photocatalytic cycles without chemical cleaning. In addition, it exhibits excellent mechanical and chemical stability when subjected to ultrasonication, abrasion, and exposure to aggressive chemicals. This multilayer strategy offers a promising route to construct high-performance, long-lasting separation membranes for advanced water treatment.

Abstract The isothermal dissolution equilibrium method was employed to investigate the phase equilibrium and phase diagram of the ternary system (Na+, Cs+//Cl––H2O) at 313.15 K. This ternary system features the coexistence of double salts and solid solutions. The solid solution, formulated as ([Cs1–x(Na·H2O)x]Cl), was characterized by wet-residue analysis, X-ray diffraction, scanning electron microscopy, energy-dispersive spectroscopy, and thermogravimetry–differential scanning calorimetry (TG–DSC). Three representative equilibrium compositions of the solid solution and their respective proportions within the crystallization region were determined, and the results were compared with those of the two pure salts (NaCl and CsCl). The physicochemical property diagrams indicate that both density and refractive index increase with rising cesium chloride content. A comparative phase diagram of the ternary system (Na+, Cs+//Cl––H2O) was constructed over the temperature range from 298.15 to 318.15 K. The results show that as temperature increases, the crystallization region of NaCl expands, whereas the crystallization regions of CsCl·2NaCl·2H2O and [Cs1–x(Na·H2O)x]Cl simultaneously contract.

AuAgNCs-NFM is used for the efficient enrichment of HMs in soil. • The detection sensitivity and accuracy for Cs, Sr, and Co are enhanced. • The LODs for Cs, Sr, and Co reach 0.078, 0.085, and 0.16 mg/kg, respectively. • The 1D-CNN model is developed to improve predictive performance. Rapid, sensitive, and accurate detection of heavy metals (HMs) in soil is of importance for ensuring food security and advancing smart agriculture. However, conventional detection methods face numerous limitations, such as complicated operations and time-consuming procedures. This study proposed a novel method using AuAg nanoclusters (AuAgNCs)-modified nanofibrous membranes combined with double-pulse LIBS (DP-LIBS) for the sensitive detection of available cesium (Cs), strontium (Sr), and cobalt (Co) in soil. The AuAgNCs-modified nanofiber membranes were utilized to efficiently adsorb Cs + , Sr 2+ , and Co 2+ from soil solution, with simultaneous DP-LIBS detection. The results revealed that the limits of detection (LODs) for Cs, Sr, and Co in soil reached 0.078 mg/kg, 0.085 mg/kg, and 0.16 mg/kg, respectively. Furthermore, a one-dimensional convolutional neural network (1D-CNN) model was developed for accurate quantitative analysis and exhibited excellent predictive performance. The residual predictive deviations (RPDs) for Cs, Sr, and Co in soil were 6.0121, 5.1844, and 6.7082, respectively. This method holds great application potential in HMs monitoring, soil risk assessment, and human health protection. Download: Download high-res image (322KB) Download: Download full-size image

Visualization of the ion exchange mechanism for 137Cs and 90Sr decontamination is important for safe radioactive liquid waste reprocessing and emergency response improvement in the event of a nuclear accident. Here, the remediation of Cs+ and Sr2+ was achieved through ion exchange using a cadmium selenidostannate, [CH3NH3]3[NH4]3Cd4Sn3Se13·3H2O (CdSnSe-1), with rapid exchange kinetics, high β/γ radiation resistances, broad pH durability and facile elution. The framework constructed from mono-lacunary supertetrahedral clusters features a great negative charge density of 3.27 × 10−3 that accounts for the superhigh exchange capacities of 371.4 (Cs+) and 128.4 mg g−1 (Sr2+). Single-crystal structural analysis on the exchanger during the “pristine–ion exchange–elution” cycle supplies instructive information to elucidate the uptake and recycle mechanism for Cs+ and Sr2+. The broken symmetry of the cluster caused by a vacant site, combined with the co-templating effects of mixed methylammonium/ammonium, contributes to the formation of voids I and II that show adsorption activity for both Cs+ and K+ ions. In comparison, the divalent Sr2+ ions with higher hydration degree exchange with (alkyl)ammonium cations in a 1 : 2 molar ratio, resulting in its location at a new void (III) closer to the framework and thus a higher binding strength. The energy variation during the adsorption process based on a DFT calculation illustrates the high efficiency of CdSnSe-1 for capture of both Cs+ and Sr2+. This “visualized” ion exchange underlines the robustness and flexibility of CdSnSe-1 as a Cs+ and Sr2+ trapper, and reveals the deeper structure–function relationship from a new surface interaction viewpoint.

Vertical-oriented Cs-doped rutile TiO 2 nanorod (Cs-TiO 2 NR) arrays were prepared without a seed layer through the hydrothermal method . One-dimension TiO 2 nanorod (TiO 2 NR) arrays not only provide a direct and fast channel for charge transfer but also increase the perovskite loading amount. Further research shows that the conduction band minimum of Cs-TiO 2 NRs increases from − 3.94 eV to − 3.86 eV when compared with the pristine TiO 2 NRs, which favors the positive band alignment at the ETL/perovskite interface and reduces the carrier recombination and energy loss. Furthermore, we simultaneously replaced the expensive and unstable organic hole transport layer and noble metal electrode with a carbon electrode for the purpose of reducing the cost of the PSCs . The study proves that Cs-TiO 2 NRs not only improve the energy level arrangement at the ETL/perovskite interface but also reduce the density of defect states at the interface and increase carrier lifetime. The hole-transport-material-free carbon-based all-inorganic FTO/Cs-TiO 2 NRs/CsPbI 2.25 Br 0.75 /C solar devices exhibited a high-power conversion efficiency (PCE) of 12.72%, showing a 16% increase in PCE when compared with the control device. This work opens the door to the preparation of high-efficiency hole-transport-material-free carbon-based all-inorganic PSCs via the energy level calibration engineering.

The need for high-performance and novel technologies for selective treatment of radionuclides in water has recently stimulated broad research. In this study, we examined the ability of carbon nanotube (CNT) membranes in selective removal of strontium (Sr 2+ ) and cesium (Cs + ) from water and wastewater. In single-metal systems that contained only Sr 2+ , Cs + or their competitive metal ions, the distribution coefficients ( K d ) of functionalized CNT membranes for divalent cations, i.e., Sr 2+ , Ca 2+ , and Mg 2+ , were measured as 4.41 mmol g −1 , 2.14 mmol g −1 , and 1.30 mmol g −1 , respectively, and those for monovalent cations, i.e., Cs + , K + and Na + , were 0.81 mmol g −1 , 0.79 mmol g −1 , and 0.81 mmol g −1 , respectively. When Cs + or Sr 2+ co-existed with a competing cation, both pristine and functionalized CNT membranes showed excellent selectivity to Sr 2+ over Mg 2+ and Ca 2+ while their selectivity to Cs + over K + and Na + diminished. Moreover, the CNT membranes remained their selectivity for Sr 2+ in a wastewater effluent despite the complex water composition. Overall, the selectivity sequence of the CNT membranes for divalent cations support the occurrence of inner-sphere complexation on CNT surfaces, while that for the monovalent cations was probably determined by electrostatic interactions. This study demonstrates that Ar/O 2 plasma treatment is a greener technology for the production of CNT functionalized membranes for selective removal of contaminants from water to achieve “fit-for-purpose” treatment.

Currently, the most effective way to improve the anti-fouling performance of water treatment separation membrane is to enhance the hydrophilicity of the membrane surface, but it can still cause contamination, leading to the occurrence of flux reduction. The construction of a strong hydration layer to resist wastewater contamination is still a challenging task. In this study, a defect-free hydration layer barrier was achieved by grafting chitosan polysaccharide derivatives (CS-SDAEM) on the membrane, which achieved in effective fouling prevention and low flux decline rate. A layer of tannic acid-coated carbon nanotubes (TA@CNTs) has been uniformly deposited on the commercial PVDF membrane so that the surface was rich in -COOH groups, providing sufficient reaction sites. These reactive groups facilitate the grafting of amphiphilic polymers onto the membrane. This modification strategy achieved in enhancing the antifouling performance. The modified membrane achieved low contamination rate with DR of 16.9 % for wastewater filtration, and the flux recovery rate was above 95 % with PWF of 1100 (L·m −2 ·h −1 ). The membrane had excellent anti-fouling performance, which provided a new route for the future development of water treatment membrane.

Narrow band red-emitting A2GeF6:Mn4+ (A = Na, K, Rb, Cs) phosphors were prepared through a two-step precipitation–cation exchange route using a K2MnF6 precursor as the Mn4+ source. The phase purity, morphology, and constituent were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectric spectroscopy (XPS), and electron paramagnetic resonance (EPR) examination. Optical properties were investigated by photoluminescence spectra (PL and PLE) and high-resolution PL. A temperature-dependent PL examination was performed to investigate the electron–phonon coupling emission mechanism of Mn4+ in these alkali fluorogermanates. The PL data show that both ordered distribution and appropriate distance between Mn4+ ions are propitious for enhancement of the emission intensity. A resonance emission enhancement (REE) mechanism has been proposed to explain the intensity increment among these products. These phosphors present bright red emission under blue light (467 nm) illumination, among which Cs2GeF6:0.03Mn4+ exhibits the most excellent optical properties with a quantum yield (QY) of 93%. A WLED (white light-emitting diode) fabricated with blend of commercial YAG:Ce3+ and this phosphor emits intense warm white light with low color temperature (CCT = 3385 K) and high color rendering index (Ra = 90.5), implying its potential application as red phosphor in WLEDs.

Mn2+-doped luminescent materials play a significant role in a variety of fields, including modern lighting, displays, and imaging. Mn2+ exhibits a broad and adjustable emission, hinging on the local environment of the crystal field and the interaction of the 3d5 electrons. However, it is still a challenge to realize the precise control of the emission of Mn2+ ions due to site-prior occupation in a specific lattice. Here, the formation of Mn–Mn dimers is proposed to be an effective strategy to design a novel red emission. Multimode emitters in Mn2+-activated AZn4(PO4)3 (A = K, Rb, and Cs) with unique [Zn4PO12] chains and [ZnOn] groups are observed to achieve regular green and unusual red emissions. KZn4(PO4)3:Mn2+ shows broad dual emissions at 542 and 608 nm, attributed to [MnO4] and [Mn2O7] dimers, respectively. While K is replaced with Rb and Cs, the Zn ions form [ZnO4] tetrahedra and [ZnO5] octahedra. RbZn4(PO4)3:Mn2+ exhibits a broad red emission at 618 nm, ascribing to [Mn2O7] and [Mn2O8] dimers. CsZn4(PO4)3:Mn2+ also displays a broad orange-red emission at 608–620 nm with increasing doping levels, deriving from energy transfer from [MnO5] to [Mn2O7] and [Mn2O8] dimers. This work provides a framework for creating novel red emissions from Mn2+-doped luminescent materials.

Aeromonas sobria , recognized as a psychrotrophic specific spoilage organism in refrigerated aquatic products, facilitates its proliferation by metabolizing proteins, lipids, and carbohydrates, thereby generating spoilage-associated metabolites and compromising product quality. Quorum sensing (QS), a bacterial cell-to-cell communication mechanism, orchestrates the secretion of virulence and spoilage factors in A. sobria via the LuxI/R QS system. Targeting this regulatory pathway presents a novel strategy to mitigate spoilage and extend the shelf life of aquatic products. Previous studies have demonstrated that zingerone (ZRN) exhibits quorum-quenching activity at sub-inhibitory concentrations; however, its practical application is constrained by limited solubility and bioavailability. To overcome these challenges, ZRN was encapsulated within halloysite nanotubes (HNTs) and incorporated into a self-assembled composite film composed of chitosan (CS) and sodium carboxymethyl cellulose (CMC-Na). The fabricated film was characterized for its structural, thermal, and mechanical properties and subsequently evaluated for its preservation efficacy on refrigerated perch fillets. The composite film exhibited a homogeneous surface morphology with uniformly dispersed HNTs, alongside adequate thermal stability, tensile strength, and physicochemical attributes suitable for refrigerated aquatic product preservation. Notably, the film suppressed spoilage indicators, including total volatile basic nitrogen (TVB-N) accumulation, lipid peroxidation, and bacterial spoilage potential, without inhibiting A. sobria growth. Furthermore, it mitigated muscle tissue degradation and biogenic amine formation in perch fillets during refrigerated storage. Molecular docking simulations revealed that ZRN competitively binds to the LuxR-type receptor at the same binding pocket as the endogenous autoinducer C 4 -HSL, thereby disrupting QS signaling. Collectively, this ZRN-loaded composite film represents a promising biodegradable packaging solution for enhancing the quality and shelf life of refrigerated aquatic foods.
