Zeolite Beta single crystals with intracrystalline hierarchical porosity at macro-, meso-, and micro-length scales can effectively overcome the diffusion limitations in the conversion of bulky molecules. However, the construction of large zeolite Beta single crystals with such porosity is a challenge. We report herein the synthesis of hierarchically ordered macro-mesoporous single-crystalline zeolite Beta (OMMS-Beta) with a rare micron-scale crystal size by an in situ bottom-up confined zeolite crystallization strategy. The fully interconnected intracrystalline macro-meso-microporous hierarchy and the micron-sized single-crystalline nature of OMMS-Beta lead to improved accessibility to active sites and outstanding (hydro)thermal stability. Higher catalytic performances in gas-phase and liquid-phase acid-catalyzed reactions involving bulky molecules are obtained compared to commercial Beta and nanosized Beta zeolites. The strategy has been extended to the synthesis of other zeolitic materials, including ZSM-5, TS-1, and SAPO-34.

Vanadium oxides are a class of promising anode candidates for sodium-ion batteries (SIBs) with high theoretical capacity and low cost. However, their practical application has been impeded by the low electronic conductivity, sluggish ionic transport and large volume change upon sodiation. Herein, a novel, high-performance anode for SIBs based on an oxygen-deficient vanadium oxide (VO/V₂O₃) heterostructure embedded in porous nitrogen-doped carbon (denoted as VNC) derived by a very simple and localized phase transition from a vanadium glycolate precursor has been demonstrated. The strong synergy of the hierarchically porous framework, VO/V₂O₃ phase heterojunctions with oxygen vacancy defects, and interfacial coupling with N-doped carbon (NC) efficiently promotes the electron/ion transport and alleviates the volume change during the sodiation/de-sodiation process. Electrochemical evaluation reveals that this novel VNC anode material manifests high sodium-ion storage capability and stability. Ex situ X-ray diffraction (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS) analyses show that (a portion of) the vanadium oxides can be converted into vanadium metal and sodium oxides. First-principles density functional theory (DFT) calculations reveal that coupling with NC effectively enhances the interfacial interactions and charge transfer between vanadium oxides and carbon, as well as the conversion reaction kinetics during sodiation/desodiation. The present work offers a viable strategy for the rational design and exploration of novel heterostructure composite electrodes for a wide array of beyond-lithium-ion batteries.

Lithium-ion batteries have become dominant in the markets for portable electronic devices and electric vehicles owing to their high energy density and long cycle life. However, traditional alloy-based anode materials (such as Si, Bi, and Sn) still suffer from significant volume expansion, severe electrode pulverization, slow lithium diffusion kinetics, and low Coulombic efficiency. Intrinsic high-capacity liquid metal (LM) materials effectively mitigate the volume deformation of traditional alloy anodes during cycling through their unique deformable liquid properties. Specifically, during delithiation, the ternary alloy solid phase reversibly transforms into a binary liquid structure, and the phase transformation behavior endows the material with self-healing ability, which can spontaneously repair the cracks or pulverized structures generated during cycling. This study proposes a self-assembled dynamic encapsulation strategy based on a Ga[sbnd]Sn eutectic alloy (EGaSn), in which liquid metal nanodroplets are encapsulated via the liquid-phase self-assembly of graphene oxide (GO). The resulting LM-rGO anode exhibits excellent specific capacity (779.29 mAh g−1 after 100 cycles at 0.5 A g−1) and outstanding cycling stability (453.77 mAh g−1 after 500 cycles at 2 A g−1). The encapsulation strategy not only mitigates the volume expansion effect of alloy-based anodes but also enhances the lithium-ion transport kinetics through the synergy between its unique stress-buffering mechanism and the three-dimensional conductive network. This strategy provides an innovative solution for the development of high-performance lithium-ion batteries with self-healing functionalities. © 2025

Molybdenum carbide has been reported as an efficient and stable catalyst for reverse water-gas shift (RWGS) reaction. The conventional understanding of the mechanism suggests domination of the surface phenomena, with only surface or subsurface layers partaking in the catalytic cycle. In this study, we presented a highly active MoC catalyst from carburization process, which showed a mass-specific reaction rate over 260 μm with dynamic carbon flux in the bulk phase of the catalyst. Through Isotopic Temperature-Programmed Reaction (ITPR) analysis and Environmental Transmission Electron Microscopy (ETEM), we discerned dynamic carbon flow circulating between the α-MoC bulk phase and the gas phase reactants under the RWGS reaction atmosphere. This circulation, essential to maintaining the structural stability of the metastable α-MoC and its ultra-high reactivity, is accompanied by thorough carbon component exchange among the bulk, the surface and the gas-phase reactants during the reaction process.

Flexible pressure sensors hold great potential for electronic skins and wearable devices. However, conventional piezoresistive flexible pressure sensors often lack the ability to detect high-frequency dynamic stimuli. Here we present a piezoresistive flexible pressure sensor by combining porous materials with a pyramid array composite hierarchical structure. The sensor significantly improve the response-relaxation time and can accurately capture dynamic stimuli exceeding 20 kHz with a frequency resolution of 0.1 Hz. Meanwhile, the sensor can detect a minimum pressure of 1 Pa and has a wide pressure sensing range from 1 Pa to 1000 kPa. In addition, we developed a structural vibration detection system, a sound detection system, and a human motion detection system to verify the broadband multifunctional detection capability of the sensor. This work provides innovative ideas for the development of flexible wearable devices and electronic skins.

The amphipathic properties of surfactant macromolecules, characterized by their hydrophilic and hydrophobic terminal groups, are ubiquitously used to modulate the surface tension of interfaces and clean surfaces. Previously, the crucial role of surfactants was reported for the performance of catalytic nano/- and micromotors. In this study, we extrapolate this concept to the membraneless hydrogen peroxide (H 2 O 2 ) Fuel Cells (FCs), which exhibit performance dependence on the addition of different types of surfactants: cationic - Sodium Dodecyl Sulfate (SDS), anionic - Benzalkonium Chloride (BACl), and nonionic - Tween20. Among them, charged SDS and BACl show promotion and inhibition towards fuel cell performance, respectively. Non-charged Tween20 shows a neutral effect on fuel cell performance.

A highly efficient on-chip acousto-optic modulator, as a key component, occupies an exceptional position in microwave-to-optical conversion. Homogeneous thin-film lithium niobate is preferentially employed to build the suspended configuration forming the acoustic resonant cavity to improve the modulation efficiency of the device. However, the limited cavity length and complex fabrication recipe of the suspended prototype restrain further breakthrough in the ME and impose challenges for waveguide fabrication. In this work, based on a nonsuspended thin-film lithium niobate-chalcogenide glass hybrid Mach–Zehnder interferometer waveguide platform, we propose and demonstrate a built-in push-pull acousto-optic modulator with a half-wave-voltage-length product VπL as low as 0.03 V cm, presenting a modulation efficiency comparable to that of the state-of-the-art suspended counterpart. Based on the advantage of low power consumption, a microwave modulation link is demonstrated using our developed built-in push-pull acousto-optic modulator. The nontrivial acousto-optic modulation performance benefits from the superior photoelastic property of the chalcogenide membrane and the completely bidirectional participation of the antisymmetric Rayleigh surface acoustic wave mode excited by the impedance-matched interdigital transducer, overcoming the issue of amplitude differences of surface acoustic waves applied to the Mach–Zehnder interferometer two arms in traditional push-pull acousto-optic modulators.
