Although ion doping can enhance the luminescence properties of these compounds, the mechanism of foreign ions that undergo ultrafast diffusion into the host lattice or construct new compounds remains an open question. In this study, Sb³⁺ was doped into a KCl matrix via room-temperature grinding route. By varying the Sb³⁺ concentration, a structural evolution from KCl:Sb³⁺ to the 0D inorganic metal halides (IMHs) K₃SbCl₆ has been confirmed. The resulting K₃SbCl₆ exhibits broad-spectrum yellow emission with near-unity photoluminescence quantum yield. The luminescence mechanism can be attributed to the ³P₁→¹S₀ transition of Sb³⁺ ions, characterized by a broad emission band. Furthermore, a room-temperature solid-liquid interface diffusion method is developed for ultrafast single-crystal growth of K₃SbCl₆ (only 20 s) with stable luminescence, and demonstrated excellent temperature sensing performance within the 50–310 K range, achieving a maximum relative sensitivity of 9.99%/K. Additionally, the application potential of K₃SbCl₆ is successfully demonstrated in information encryption, flexible composite fluorescent films, and white light-emitting diodes. This study provides new insights and prospects for the ultra-fast synthesis of high-performance luminescent materials.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"69 8","pages":"4604 - 4616"},"PeriodicalIF":7.7,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among them, Cr₂AlB₂ is of great interest due to its good thermal and electrical properties. However, the conventional synthesis method of Cr₂AlB₂ needs to be carried out under inert gas protection to avoid oxidation, which greatly increases the cost and limits its development in the field of wave absorption. To resolve the issue, we have successfully synthesized high-purity Cr₂AlB₂ in air using the molten salt shield synthesis (MS³). It can not only isolate the interference of oxygen, but also reduces the synthesis temperature of Cr₂AlB₂, which is a cost-effective method. Also, Cr₂AlB₂ synthesized using MS³ exhibits excellent wave-absorbing properties. A minimum reflection loss (RL_min) of −42.10 dB at 12.6 GHz and a maximum effective absorption bandwidth (EAB_max) of 3.44 GHz are achieved at a thickness of 1.9 mm. Therefore, this study not only contributes to the large-scale synthesis of Cr₂AlB₂ materials but also offers valuable insights for its potential application in electromagnetic wave absorption.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":773,"journal":{"name":"Science China Materials","volume":"69 8","pages":"4872 - 4883"},"PeriodicalIF":7.7,"publicationDate":"2026-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148652235","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it still presents risks of iatrogenic injury from vascular access, necessitating prompt and reliable vascular closure. Although various closure systems have been developed, they often suffer from complicated deployment procedures, potential for loosening, and risk of device migration. Herein, we develop a smart self-deployable vascular closure device enabled by a semi-interpenetrating network (sIPN) that synergistically integrates a programmable shape memory effect and robust tissue adhesion. The sIPN was designed by interpenetrating flexible, dopamine-functionalized poly(tetrahydrofuran) (PTD) chains into a photo-cross-linkable poly(ε-caprolactone)-based copolymer (PCC) network. The vascular closure model was fabricated via a UV-assisted fused deposition modeling printing strategy, significantly reducing mechanical anisotropy while facilitating structural customization. The resulting device exhibits autonomous self-deployment at 37 °C, along with reliable tissue adhesion under physiological conditions (maximum shear strength of 150.5 kPa). <i>In vitro</i>, the material demonstrates exceptional hemocompatibility (below 3%) and excellently enhanced cell migration (up to 38.9%). <i>In vivo</i>, immunofluorescence analysis reveals a promotion for CD31 (162.18%) and aSMA (154.93%) compared to the control group.

In this study, we demonstrate giant electromechanical control over the magnetism of the room-temperature van der Waals ferromagnet Fe₃GaTe₂ by integrating it with the ferroelectric α-In₂Se₃. Modest gate voltages lead to an almost complete suppression of the coercive field by 96.5%, corresponding to a remarkable peak modulation sensitivity of ∼8.l mT V⁻¹, which stands out among existing van der Waals magnetoelectric systems. Importantly, this substantial magnetoelectric response is predominantly unaffected by voltage polarity, as both positive and negative gate voltages induce similar magnetic modulation effects. To elucidate the underlying mechanism, we tracked the voltage-induced Raman spectral changes, revealing a peak shift of 1.7 cm⁻¹ that accurately represents an effective in-plane tensile strain of ∼l.42% under an equivalent bias, demonstrating polarity independence as well. The synchronized magnetic response and strain variation unequivocally indicate that the induced tensile strain serves as the fundamental physical driver behind the magnetic modulation. Additionally, density functional theory calculations corroborate that the reduction in magnetic anisotropy induced by tensile strain results in a decrease in the coercive field.

We first outline four major synthesis routes: thermal activation, solvent-mediated strategies, energy-intensive methods and template-etching approaches, enabling high loading, stable anchoring and scalable, environmentally compatible production. We then dissect the multimodal antibacterial mechanisms of Cu-SACs: functioning as nanozymes to catalyze reactive oxygen species (ROS) generation; acting as photosensitizers to enable photocatalytic and photothermal bactericidal activity; and integrating these pathways with gas therapy, controlled ion release and immune modulation to construct multidimensional antimicrobial networks capable of eradicating drug-resistant bacteria and biofilms. We further discuss the substantial potential of Cu-SACs across three application domains: chemical-free, high-efficiency disinfection and real-time monitoring in water purification; durable self-disinfecting performance in antimicrobial textiles; and precision infection management in biomedical settings through integrated “bactericidal-anti-inflammatory-tissue-repair” therapeutic frameworks for both superficial and deep-tissue infections.

Anion intercalation engineering has emerged as a powerful strategy to systematically address these challenges. By inserting functional anions, ranging from simple inorganic ions and polyoxometalates to organic molecules, into LDH interlayers, it is possible to expand interlayer spacing for improved mass transport, directly modulate the electronic structure of metal centers to boost intrinsic OER activity, and create a negatively charged interfacial microenvironment that selectively enriches OH⁻ due to its superior ability to participate in the interfacial reaction network.
