Heavy metal pollution in industrial effluents continues to be a major obstacle to environmentally friendly water reuse. To effectively remove heavy metal ions from wastewater, a unique Zeolite-NaX-doped polyethylene terephthalate–polysulfone membrane (Zeolite-NaX@PET-PSF) was synthesized and tested for nanofiltration wastewater treatment. The resulting membrane demonstrated remarkable mechanical integrity, maintaining a stable permeate flux of about 16 ± 0.52 L m − 2 h − 1 at an operating pressure of 10 bars without collapsing structurally. Batch and filtration tests demonstrated excellent rejection of lead, chromium, and cadmium ions, with removal efficiency as high as 99%. Cobalt, mercury, and manganese had rejection rates of 55%, 75%, and 64%, respectively, which was due to their difficulty in removal. In all filtering cycles, near-total removal of Cd 2+ , Cr 3+ , and Pb 2+ was confirmed by inductively coupled plasma–optical emission spectrometry and surface composition of the treatment membrane using energy-dispersive spectroscopy. The hydrophilic change of the membrane surface and the production of nanoscale porosity were verified by complementary BJH, contact angle, XRD, FTIR, SEM/EDX, and TEM investigations. The Zeolite-NaX@PET-PSF composite membrane is a promising platform for advanced wastewater treatment targeting heavy metal contamination.

Heterointerface engineering is a catalyst design strategy based on the symbiotic growth of heterogeneous metal oxides. This strategy endows electronic structures, surface properties, and generation of active centers that are unavailable in the individual oxides. It can even generate entirely new active sites, thereby significantly enhancing catalytic performance. Herein, we prepared MoO 3 @Cu x O with symbiotic MoO 3 and CuO as a catalyst for aerobic catalytic oxidative desulfurization. Notably, after symbiosis, the catalyst exhibits new low-valence Cu + active sites absent in the individual oxides, along with defective interfaces more favorable for catalytic reactions and enhanced surface redox properties. Catalytic testing validates these findings: these new low-valence Cu + active sites enable the activation of superoxide radicals, achieving 100% desulfurization of aromatic sulfur compounds under air atmosphere within 5 h. Through the rational design of symbiotic heterogeneous metal oxides, this study not only highlights the pivotal role of heterointerface engineering in catalytic oxidation but also offers an effective strategy for designing oxidative desulfurization catalysts.

Ammonia (NH 3 ) synthesis via nitrate reduction offers a sustainable energy conversion and mitigates aquatic NO 3 − pollution, yet most catalysts require high overpotentials for appreciable NH 3 yields. Here, we report a sulfur-leaching strategy to transform Cu 1.8 S/Ru heterostructures into a small CuRu-Cu 2 O nanocomposite with abundant heterointerfaces, enabling strong electronic coupling between CuRu and Cu 2 O particles, synergistically enhancing NO 3 – adsorption and reaction kinetics. The optimized catalyst achieves 95.4% NH 3 Faradaic efficiency at a low potential of 0.0 V versus reversible hydrogen electrode, stable over 30 cycles. Operando spectroscopy and density functional theory calculations reveal the incorporation of Ru facilitates active hydrogen generation, alleviating the energy barrier for hydrogenation steps at heterointerfaces. The catalyst demonstrates high stability in a membrane electrode assembly at 450 mA cm –2 over 200 h and enables a Zinc-NO 3 – battery operation exceeding 50 h, offering a design model for durable, active nanocomposites in sustainable NH 3 synthesis.

Co-free Ni-rich layered oxide cathodes hold great promise for cost-effective, high-energy lithium-ion batteries, but their practical application remains limited by sluggish Li + kinetics and rapid capacity fading. Although doping has been widely used to mitigate these issues, conventional trial-and-error dopant selection remains inefficient for guiding rational materials development. Here we move beyond empirical dopant screening by developing a descriptor-informed multi-component dopant selection strategy based on dopant charge density and metal–oxygen bond strength. Low-charge-density dopants reduce electrostatic barriers to Li + migration, while high-bond-energy dopants reinforce the oxygen sublattice and stabilize the metal–oxygen framework. This doping strategy simultaneously accelerates Li + kinetics, suppresses cycling-induced phase transitions and mitigates chemomechanical fatigue, thereby delivering exceptional electrochemical performance in Co-free Ni-rich cathodes. The enhanced apparent Li + transport and structural stability enable an ultrahigh-rate capability of 130.9 mAh g −1 at 25 C and at 25 °C, excellent cycling retention of 82.4% after 350 cycles at 10 C and robust low-temperature operation delivering 112.2 mAh g −1 at 1 C under −20 °C. These findings, transitioning the design principle from empirical or trial-based selection to a targeted selection regime, present a promising route for developing high-performance cathode materials for lithium-ion batteries.

Despite progress on noble-metal high-entropy alloy catalysts, noble-metal-free high-entropy alloy catalysts continue to face limitations in activity and stability. Atomic defect engineering holds promise for unlocking catalytic potential, yet efficient strategies for designing defects to simultaneously tailor electronic structures and enhance catalytic active sites in noble-metal-free high-entropy alloys remain challenging. Here, we report a general rule to drive twin formation via precisely tuning lattice strain in metallic nanomaterials. By modeling twin formation energy as a descriptor and employing a gradient-radius hetero-atomic doping strategy, we derive a generalized lattice strain-twin formation energy function that determines critical strain for twinning propensity. Guided by this principle, Ce is incorporated into CuCoNiMnMo nanoparticles, promoting coherent five-fold twinning along {111} planes. Twin boundaries generate high-activity sites by disrupting atomic symmetry and reducing coordination numbers, while modulating band width via altered orbital overlap. Meanwhile, strong Ce-O affinity forms an amorphous CeO x passivation layer on twinned noble-metal-free high-entropy alloy, triggering hetero-interfacial electron transfer. These effects synergistically optimize reaction kinetics. Consequently, the engineered catalyst achieves a 405-cycle lifespan in lithium–oxygen batteries and operates across −20 to 80 °C. Our study brings fundamental insights into defect engineering for electrocatalysis in energy conversion fields.

Interfacial defects, particularly those of intergranular origin, are a persistent challenge limiting the performance of modern optoelectronic devices. Conventional three-dimensional and low-dimensional (two- or one-dimensional) semiconductors all suffer from surface or edge-related bonding discontinuities that degrade the carrier dynamics and optical efficiency. Here we report on a new semiconductor design strategy based on zero-dimensional structured materials, which inherently lack dangling bonds along all crystallographic directions. By introducing anisotropic chemical bonding within the zero-dimensional framework, we can achieve customizable morphologies—such as rods—without compromising the isotropic and defect-free electronic properties. Using the uranyl-based halide Cs 2 UO 2 Cl 4 as a model, we exploit the bonding disparity between U=O and U–Cl to drive anisotropic crystal growth. When applied to X-ray scintillation imaging, columnar structured Cs 2 UO 2 Cl 4 achieved a high spatial resolution (34 lp mm −1 ). This work introduces a generalizable approach for decoupling material geometry and electronic dimensionality, offering a new platform for high-performance, defect-tolerant semiconductors.

Interorgan communication is vital for tissue homeostasis and health in multicellular organisms, and its disruption can lead to diseases such as cancer. Adipose tissue acts as a key endocrine center, secreting cytokines that influence remote organs. Despite clear links between obesity and increased cancer risk, the underlying mechanisms are unclear. Here, utilizing a Drosophila genetic model combining Gal4-UAS and QF-QUAS tissue-specific transgene expression systems, we reveal that adipose-secreted Spz5 ligand promotes distal epithelial tumor overgrowth and invasion. Mechanistically, Spz5 binds to tumor cell Toll-6 receptors, triggering the degradation of the endocytic adaptor protein AP-2α via Mib1-mediated ubiquitination. Consequently, impaired endocytosis leads to Smoothened (Smo) accumulation on the cell membrane and subsequent activation of the Hedgehog (Hh) pathway. This abnormal Hh activation synergizes with the oncogenic Yorkie (Yki) to drive tumor growth and invasion. Furthermore, tumor-derived Unpaired ligands (Upds) activate the JAK-STAT pathway in the fat bodies, which leads to Hippo pathway-dependent upregulation of spz5 expression. Thus, our study provides insights into the complex regulatory mechanisms by which systemic interorgan communication influences tumor progression.

The fly ash water treatment filler prepared using the foaming method is characterized by low energy consumption and a simple preparation process, effectively promoting the resource utilization of fly ash. To further enhance the filler's water treatment performance, this study employed the co-precipitation method to synthesize Fe 3 O 4 magnetic particles and optimize the magnetic modification of the foamed fly ash filler. The results show that the specific surface area of the magnetically modified foamed fly ash filler increased by 30.51%, and the average pore diameter increased by 26.47% compared with the original filler before modification. In the simulated domestic wastewater treatment test, the magnetically modified filler achieved COD and ammonia nitrogen removal rates of 74.61% and 70.18%, respectively. These values are higher than those of the unmodified and sintered ceramic fillers and represent improvements of 21.99% and 9.76% over the unmodified filler. Illumina MiSeq sequencing revealed that the microbial community on the magnetically modified filler was more abundant, with Proteobacteria and Bacteroidetes as the dominant phyla. Magnetic modification is more effective in promoting the formation of biofilms on the surface of fillers, enhancing microbial diversity, and increasing the proportion of functional bacteria.

The strategic integration of functional monomers within the molecular structure of polycarboxylate superplasticizers offers a viable route to augment their inherent performance capabilities or introduce novel functionalities. In this investigation, a novel silane-modified polycarboxylate superplasticizer (Si-PCE) was synthesized via a free radical polymerization process at room temperature. This synthesis leveraged the high reactivity of ethylene glycol monoethylene glycol ether (EPEG), acrylic acid, and vinyltriethoxysilane (VTEO) as the core monomers. The chemical structure of Si-PCE was characterized by Fourier transform infrared spectroscopy (FTIR), 1 H Nuclear magnetic resonance ( 1 H NMR), and Energy dispersion spectroscopy. To evaluate the performance of Si-PCE, its influence on the early hydration products of cement was analyzed using X-ray Diffraction (XRD). Furthermore, the dispersibility of Si-PCE was assessed through cement paste fluidity and mortar fluidity tests, while its impact on mechanical property was investigated via mortar strength measurement. The findings revealed that Si-PCE surpassed silane-free PCEs in terms of dispersibility and dispersion retention, leading to enhanced mechanical property. In addition, the adaptability of Si-PCE in sulfate-rich environments was examined by conducting cement paste fluidity, mortar fluidity, and mortar compressive strength tests. Notably, Si-PCE demonstrated superior performance compared to its silane-free counterpart, particularly in high-sulfate environments, where it effectively dispersed cement particles and significantly bolstered the mechanical property of cement mortar. In conclusion, Si-PCE exhibited not only superior performance under conventional conditions but also remarkable adaptability and stability in sulfate-rich environments, thereby portending its extensive potential for application and profound implications.

Literature reports indicate that existing synthesis methods for leveling agents often suffer from complex procedures, high environmental burden, challenging purification processes, and insufficient via filling efficiency. To address these limitations, a novel leveling agent (CDT) was synthesized using environmentally friendly materials through a simplified, cost-effective process that eliminates the need for post-synthesis purification. This study systematically investigates the influence of CDT on blind via filling performance in an acidic copper sulfate plating bath containing polyethylene glycol (PEG), bis(3-sulfopropyl) disulfide (SPS), and chloride ions. The chemical structure of CDT was characterized by Fourier-transform infrared spectroscopy (FTIR), nuclear magnetic resonance (NMR), and gel permeation chromatography (GPC). Quantum chemical calculations and molecular dynamics (MD) simulations revealed that CDT exhibits stronger adsorption on copper surfaces compared to conventional leveling agents. Electrochemical measurements confirmed its ability to suppress copper deposition and helped determine the optimal working concentration of CDT. Electroplating experiments further demonstrated CDT’s capability to achieve superfilling, indicating its suitability for printed circuit board (PCB) manufacturing. Scanning electron microscopy (SEM) results corroborated the validity of the optimal concentration established by electrochemical tests. Finally, X-ray photoelectron spectroscopy (XPS) confirmed strong interfacial interactions between CDT and the copper surface. These findings collectively suggest that CDT is a highly promising candidate for advanced leveling agent applications.

Imidazolium-based hexafluorophosphate ionic liquids (ILs) have attracted widespread interest due to their unique physicochemical properties. Accordingly, in this work, four kinds of diimidazolium hexafluorophosphate ILs with different cation structures were synthesized and characterized. Moreover, their stability (e.g., thermal stability, oxidation-reduction stability, and acid-base stability), and catalytic performance in furfural coupling were systematically explored to elucidate the correlation between their physicochemical properties and cation structures. Thermal stability results showed no weight loss within 250 °C, and the cations in ILs with shorter R-groups or linked via an alkyl carbon chain correlated with better thermal stability. Moreover, the conventional oxidation-reduction stability of the ILs was not desirable, but they displayed promising electrochemical stability. Among them, the cations with longer R-groups or linked via the phenyl group were correlated with a wider window of electrochemical stability. Notably, they also displayed a correlation with better acid-base stability, and more resistance to alkaline environments (pH = 13) compared to acidic environments (pH = 1). Furthermore, ILs could also realize furfural coupling with a 60.48% furoin yield in an alkaline environment. Overall, the correlation between the cation structures of ILs and their physicochemical properties was revealed, and the ILs with longer R-groups or linked via the phenyl group displayed better prospects. This work may provide insights into the future design and application of ILs.

Developing a promising on-demand controllable microneedle drug delivery system could provide stronger self-control and precision delivery of a large payload capacity. Nevertheless, the efficacy of existing systems has been constrained by limitations in the therapeutic payload capacity and slow diffusion of molecules, as well as the necessity for external resource configurations. Drawing inspiration from the multidimensional biomimetic strategies observed in the material properties and functional mechanisms of the bombardier beetle’s defensive secretion system, a battery-free and self-propelled biomimetic microneedle system (BSBMs) is proposed for improving therapeutic outcomes and enabling controlled, on-demand drug delivery. The self-powered microneedle delivery platform fully emulates the structure and spray mechanism of bombardier, employing Pt nanoparticles and H 2 O 2 loaded in the reaction chamber, as a built-in fuel source for active and controllable payload delivery. The robust bionic gas injector can serve as an active engine, facilitating the effective permeation of drugs through hollow microneedles without a complex pumping system. This BSBMs triggers the H 2 O 2 decomposition reaction through thumb pressure, generating O 2 pressure as an endogenous driving force to achieve transdermally precise and on-demand drug delivery. The pharmacokinetics of drug release from the BSBMs were evaluated in vivo by quantifying the levels of levonorgestrel (LNG). This active delivery system maintains in vivo LNG concentrations within the therapeutic window range, greatly enhancing on-demand, controlled, and stable drug delivery. This versatile and efficient self-propelled bionic microneedle delivery technology holds substantial promise for a broad spectrum of transdermal therapeutic applications, offering a simplified, convenient, and improved method of administration.
