Crafting a sustainable non-aqueous electrolyte is paramount in the pursuit of high-voltage lithium batteries that exhibit exceptional performance. Traditional carbonate-based electrolytes encounter hurdles in maintaining electrochemical stability due to unstable interphases, as well as continuous degradation of the electrolyte itself. Herein, based on heterogeneous doping, a colloidal electrolyte with multiple functions via simple integrating methyl-encapsulated fumed silica (MFS) into a conventional carbonate-based electrolyte effectively addresses the aforementioned challenges. The produced colloidal electrolyte endowed with unexpected self-purification capabilities effectively eliminates HF and H2O, consequently enhancing stability of the electrolyte, interphase, and electrode. Furthermore, MFS induces a weakly solvated Li+ structure that is heterogeneously doped into the original solvation matrix and contributes to the formation of tailored and stable electrode/electrolyte interphases for both anode and cathode. Using such electrolyte, Li||LiCoO2 batteries demonstrate capacity retentions of 83.6% and 95.4% within 3000 and 1000 cycles at charging voltages of 4.4 and 4.5 V, respectively. Remarkably, with addition of 2000 ppm H2O in this electrolyte, cells can be cycled stably over 400 cycles with a capacity retention of 88.6%. This simple and effective electrolyte engineering strategy has the sustainability to significantly advance the development of highly stable high-voltage lithium batteries.

Wearable sweat sensors offering real-time monitoring of biomarker levels suffer from stability and accuracy issues, primarily due to low biomarker concentrations, fluctuating sweat pH, and material detachment from sensor deformation. Here, we developed a wearable sensing system integrated with two advanced electrodes and a flexible microchannel for long-term reliable monitoring of sweat pH and uric acid (UA). By printing the ink doped with nanomaterials (Co3O4@CuCo2O4 and polyaniline), we achieved highly stable electrodes for the direct analysis of perspiration, without additional surface modification. Additionally, real-time pH analysis provided a means for sensitivity calibration, reducing the effect of individual metabolism and exercise intensity. As a result, the wearable sensing system for effective gout management was validated by accurately tracking the UA fluctuations in serum and sweat of hyperuricemia patients and healthy individuals. These findings offer a reliable method for tracking biomarkers to assess personal health.

High salinity in wastewater often hampers the performance of traditional adsorbents by disrupting electrostatic interactions and ion exchange processes, limiting their efficiency. This study addresses these challenges by investigating the salt-promoted adsorption of Cu ions onto amino-functionalized chloromethylated polystyrene microspheres (EDA@CMPS). The adsorbent was synthesized by grafting ethylenediamine (EDA) onto CMPS, which significantly improved Cu adsorption, achieving nearly three times the capacity in saline solutions (1.65 mmol/g) compared to non-saline solutions (0.66 mmol/g). Mechanistic analysis showed that the presence of salts, such as NaCl, promoted the protonation of amino groups on EDA@CMPS, increasing their positive charge and enhancing their affinity for Cu ions. The solution's ionic strength further amplified this protonation, reducing electrostatic repulsion between the adsorbent and Cu ions, thus improving binding efficiency. Additionally, the increased ionic strength altered Cu speciation, favoring the formation of Cu(NH₃)₄²⁺ complexes, which were more easily adsorbed. These synergistic effects resulted in faster adsorption kinetics, higher capacity, and improved Cu ions removal, particularly in saline environments. Overall, these findings bridge the gap between material design and functional performance in high-salinity wastewater, offering a promising strategy for efficient heavy metal removal and environmental remediation.

High-performance deep ultraviolet (DUV) spectroscopy is crucial in driving innovations for biomedical research, clinical diagnosis, and material science. DUV resonant nanostructures have shown capabilities for significantly improving spectroscopy sensitivity. However, they encounter significant challenges in practical applications, including instability due to oxidation and light-induced damage, and the strong photoluminescent noise background from their constituent materials. An efficient and robust DUV spectroscopy platform based on the polaritonic properties in all-dielectric silicon (Si) metasurfaces is proposed. Unlike conventional dielectric metasurfaces that rely on Mie-type modes, this approach leverages the polaritonic resonances in Si nanostructures—a striking yet underexplored property driven by interband transitions in the DUV regime—for nanophotonic sensing. A polaritonic Kerker-type void metasurface providing strong near-field enhancement localized on the surface is designed and fabricated. The metasurface facilitates double-resonance Raman scattering, a process that reveals key information about lattice dynamics and electronic structures, for analyzing 2D semiconductor monolayers. It also demonstrates superior stability in solvents and enhances biomolecule autofluorescence. These capabilities demonstrate the versatile potential of Si metasurfaces as a scalable, robust platform for interdisciplinary DUV spectroscopy applications, including advanced biomedical research and the investigation of emerging nanomaterials.

Metal-organic framework (MOF) membranes have emerged as a breakthrough technology for gas separation, offering unparalleled selectivity and permeability due to their high surface area, tuneable pore size, and versatile chemical functionalities. Encompassing the immense recent progress in the development of MOF-based membranes as supported thin layers as well as mixed matrix membranes (MMMs), this review is focussed on recent developments such as electrodeposition, use of glassy MOFs, two-dimensional (2D) MOF nanosheets and use of artificial intelligence (AI) to assist in the design of MOF membranes. Each type of MOF membrane presents unique advantages: polycrystalline membranes excel in molecular sieving, thin-film composite membranes provide enhanced gas permeance, MMMs combine MOF properties with polymer flexibility, and MOF glass membranes offer exceptional stability under harsh conditions. The comprehensive development of MOF membranes promises to revolutionize gas separation technologies, significantly contributing to environmental sustainability and economic efficiency. Finally, future advances in MOF membranes will focus on improving stability, scalability, and integration into industrial processes, with key research areas including improving chemical and thermal stability, developing scalable synthesis methods, and employing AI and machine learning for material optimization

Due to the rapid growth in the miniaturization, portability, and flexibility of electronic devices, the demand for polymer composites with high thermal conductivity and electromagnetic shielding properties has increased significantly. Herein, we present a multifunctional thin film with a Janus-like structure that simultaneously enhances conductivity and electromagnetic interference shielding effectiveness. Owing to the unique Janus-like structure, heating performance tests show that the composite film has a high Joule heating temperature of 129.4 °C at a low supply voltage of 3.0 V, a fast response time of less than 12 seconds, and excellent sensitivity, heating stability and reliability. In addition, the electromagnetic interference shielding effectiveness of AgNWs-Fe3O4/ANF can reach 80.0 dB at 8.5 GHz. This excellent performance of this multifunctional bilayer composite film demonstrates its potential for advanced electronic applications such as wearable devices, artificial intelligence and high-performance heating devices.

Obtaining hydrogen through photocatalytic water decomposition presented a reliable strategy to alleviate the energy crisis. ZnIn2S4 is a promising candidate for photocatalysts, however, the application of ZnIn2S4 was severely inhibited due to the recombination of photogenerated carriers and the slow surface reaction kinetics. In order to enhance the photocatalytic hydrogen evolution performance of ZnIn2S4, transition metal phosphide (TMP) catalysts with different numbers of transition metal elements were synthesized and compounded with ZnIn2S4 in this work. The TMP/ZnIn2S4 composite photocatalyst constructed a direct Z-scheme heterojunction to effectively inhibit the recombination of carrier recombination. Additionally, the multiple metal phosphides accelerated reaction kinetics, acting as co-catalysts to further enhance the photocatalytic performance. Meanwhile, with the increase in the transition metal elements, the catalytic reaction kinetics of TMPs was improved significantly while the charge transfer resistance gradually declined because of the synergistic effect between different metal atoms. The bifunctional multiple transition metal phosphide modification of ZnIn2S4 resulted in (MnFeCoNi)Px/ZnIn2S4 exhibiting the best photocatalytic performance with a hydrogen evolution rate of 2796.17 μmol/(h·g), which is approximately twice that of the pure ZnIn2S4 catalyst. This work provided a strategy for optimizing the photocatalytic hydrogen production of ZnIn2S4 and a comprehensive approach to investigate the mechanism of multiple transition metal phosphide catalysts.

Marine energy, a renewable source within blue energy, offers substantial potential for various applications. However, harnessing wave energy effectively poses challenges due to its irregular and unpredictable nature. Triboelectric nanogenerators (TENGs) are particularly well-suited for marine energy collection because of their lightweight design, cost efficiency, and high energy conversion rates at low frequencies. This paper provides an in-depth review of TENGs used in marine energy harvesting by analyzing their operational mechanisms, structural innovations, performance improvement methods, and real-world applications. The main features of TENG structures are evaluated, along with strategies aimed at optimizing their performance and predicting future trends.

Recently discovered skyrmion phases have provided the research communities a great opportunity to study and understand novel spin-structure arrangements which are quite different than many known regular magnetic ordering. However, the direct observation of skyrmion spin structure requires very specialized experimental facilities, although some laboratory-based experiments, viz., magnetocaloric effect (MCE) studies can often able to provide sufficiently strong indications. Using these techniques recently a number of Gd-based intermetallic compounds e.g. Gd2PdSi3, Gd3Ru4Al12 and GdRu2Si2 was established to host skyrmion phases. In this work, we have reported MCE properties of Gd2Ir0.97Si2.97 and showed that the results are very similar to that expected in a skyrmion system. Additionally, the value of adiabatic temperature change (ΔTad) around its Neel temperature was found to be quite high and has been argued to have originated due to the presence of magnetic frustration, coupled with large ground state degeneracy.
