Two-dimensional (2D) materials, recognized for their atomic-level thickness, high specific surface area, and robust chemical adaptability, significantly reduce ion transport resistance and improve sieving selectivity in membrane separation. This review focuses on recent advancements in 2D material membranes for ion-selective separation, delving into the fundamental properties of 2D materials for membrane fabrication, their synthesis and preparation methods, their classification based on electrical properties, and strategies to enhance ion selectivity and ion permeability. It also explores applications at the forefront of desalination, osmotic energy conversion, and acid recovery. Furthermore, this review discusses developmental challenges and future research directions related to vertical 2D nanochannels, anion-exchange membranes, large-scale preparation, structure stability, 2D material assembly, and mass transfer mechanisms.

Arene-perfluoroarene interaction is a unique form of π-π interaction that has gained attention in recent years. This review begins by introducing the properties of arene-perfluoroarene interaction to highlight its significant difference from arene-arene interaction. Through employing density functional theory (DFT) calculations, we elucidate the binding affinities of diverse arene-perfluoroarene interaction pairs. Moreover, manifold self-assembly constructions arise from the varying binding affinities of arene-perfluoroarene interaction in solid and solution phases. The impact of arene-perfluoroarene interaction in materials science is significant, with numerous examples covering various popular categories of materials, such as graphenes, perovskites, and hydrogels, as well as functions, such as organic luminescent materials, solar cells, and biological engineering materials. This review is expected to offer guidance on the application of arene-perfluoroarene interaction in materials science, providing an alternative tool for current challenges in the field.

The development of inexpensive and easily processable X-ray-sensitive materials is of great importance because a number of commercial scintillators, such as LaBr3(Ce), Gd3Al3Ga2O12(Ce), Cs2HfCl6, NaI:Tl, CsI:Tl, and LiI:Eu, are fabricated using highly toxic or rare-earth elements via high-temperature synthesis. This has spurred research into radioluminescence-enhancing mechanisms and solution-processable scintillating materials made from earth-abundant elements that have excellent optoelectronic properties, including high quantum yields and a low afterglow effect. In recent years, a range of metal halide perovskite (MHP) integrated with thermally activated delayed fluorescence (TADF) materials have been developed, exhibiting excellent scintillation properties and a high spatial resolution. Meanwhile, plasmonic technologies are reported to exploit light-energy confinement capabilities beyond the diffraction limit that produces local-field enhancement. This enhancement has subsequently improved the performance of small-sized optoelectronic devices such as solar cells and diagnostic optical sensors. This perspective summarizes the current development of innovative MHP, TADF, and plasmonic materials for use in scintillators and their integrated moieties while also identifying the relevant challenges. Following a thorough evaluation of the efforts made to improve the X-ray scintillation efficiency of these materials, we propose an outlook for future research in order to further enhance their scintillation properties and spatial resolution.
由于许多商用闪烁体，如 LaBr3(Ce)、Gd3Al3Ga2O12(Ce)、Cs2HfCl6、NaI:Tl、CsI:Tl 和 LiI:Eu，都是使用剧毒或稀土元素通过高温合成制造的，因此开发廉价且易于加工的 X 射线敏感材料具有重要意义。这激发了人们对放射发光增强机制和溶液可加工闪烁材料的研究，这些材料由丰富的地球元素制成，具有优异的光电特性，包括高量子产率和低余辉效应。近年来，一系列集成了热激活延迟荧光（TADF）材料的金属卤化物过氧化物（MHP）已被开发出来，显示出优异的闪烁特性和高空间分辨率。与此同时，据报道等离子体技术利用了超越衍射极限的光能约束能力，从而产生局部场增强。这种增强随后提高了太阳能电池和诊断光学传感器等小型光电设备的性能。本视角总结了目前用于闪烁体及其集成分子的创新型 MHP、TADF 和等离子材料的发展情况，同时也指出了相关的挑战。在全面评估了为提高这些材料的 X 射线闪烁效率所做的努力之后，我们对未来的研究提出了展望，以进一步提高它们的闪烁特性和空间分辨率。

Cr2TiC2Tx is an ordered double-transition-metal MXene with peculiar magnetic properties. Previous studies produced sub-1-μm sheets of Cr2TiC2Tx, which prevented complete characterization of its intrinsic properties at a single-flake level. We report the synthesis of high-quality Cr2TiC2Tx monolayers with lateral sizes exceeding 15 μm for single-flake measurements. These measurements establish Cr2TiC2Tx as a unique material among the MXenes experimentally tested so far. Field-effect electrical measurements on Cr2TiC2Tx monolayers revealed an average conductivity of 180 S cm−1 and p-type transport, while established MXenes, such as Ti3C2Tx and Nb4C3Tx, demonstrated n-type behavior. In contrast to negative photoresponse reported for Ti3C2Tx flakes, Cr2TiC2Tx devices show positive photoresponse to visible and infrared light. Nanoindentation measurements of monolayer Cr2TiC2Tx membranes yielded an effective Young’s modulus of 220 ± 22 GPa. Density functional theory calculations provide insights into the p-type character of Cr2TiC2Tx and predict its potentially tunable p-/n-type behavior depending on the concentrations of Cr vacancies, oxygens substituting carbon atoms, and surface terminations.

Increasing extreme heat stress puts humans at risk of heat stroke and dehydration in outdoor environments. However, current personal thermal management (PTM) approaches in hot summers suffer from low cooling efficiency. Here, we designed a lightweight, hierarchically porous hydrogel (HPHG) with low density, robust breaking strength, high evaporation enthalpy, high solar reflectance, and infrared emissivity, and controlled evaporation speed. The HPHG shows strong and prolonged passive cooling: sub-ambient temperature cooling up to 22.5°C under direct sunlight and a prolonged cooling time of >15 h. The HPHG can also be fabricated into a lightweight cooling vest (<350 g), achieving an average temperature drop of 11°C compared to air temperature. The concept of HPHG proposed in this study opens an avenue for hydrogel as a lightweight and wearable material in PTM and solves the bottleneck problem of passive cooling under extreme heat stress in an outdoor environment.

Energy absorption capability is critical in biological and engineering materials, particularly when subjected to extreme compressive and impact loading. In the current work, we demonstrate how natural biological materials, like horns and hooves, control crack generation and propagation through lamellar and tubular structural designs. Inspired by these biological tissues, lamellar and tubular structures were fabricated via multi-material three-dimensional (3D) printing. The resulting bioinspired structures exhibit an impressive energy absorption density of ∼18.75 kJ kg−1, comparable to the performance of metal foams and bioinspired honeycomb structures. Introducing soft-hard interfaces in lamellar and tubules notably enhances impact energy absorption by approximately 167% compared to solid structures printed with a single material. The bioinspired structures maintain structural integrity even under high-strain-rate impacts of around 2,000 s−1, showcasing resistance to deformation and catastrophic failure. This bioinspired approach allows for a combined energy absorption capability in quasi-static compression and high-strain-rate impact scenarios.
