Although hexagonal 2D MOFs generally display impressive electrical conductivity because of their dual in-plane (through bonds) and out-of-plane (through π-stacked ligands) charge transport pathways, notable differences between these two orthogonal conduction routes cause anisotropic conductivity and lower bulk conductivity. To address this issue, we have developed the first redox-complementary dual-ligand 2D MOF Cu<sub>3</sub>(HHTP)(HHTQ), featuring a π-donor hexahydroxytriphenylene (HHTP) ligand and a π-acceptor hexahydroxytricycloquinazoline (HHTQ) ligand located at alternate corners of the hexagons, which form either parallel HHTP and HHTQ stacks (AA stacking) or alternating HHTP/HHTQ stacks (AB stacking) along the c-axis.

Boron nitride nanosheets (BNNS) have emerged as promising fillers for thermally conductive epoxy based composite. However, the improvement of composite thermal conductivity is often constrained by interfacial thermal resistance (ITR) at filler-filler and filler-matrix interfaces. The smooth and inert surface of BNNS exacerbates this challenge. To address these issues, silver nanoparticles (AgNPs) are in situ synthesized on BNNS surfaces through a simple annealing process. The BNNS-Ag fillers are subsequently modified using 3-(Mercaptopropyl)triethoxysilane (MPTS) to enhance filler-polymer matrix interactions through thiol-silver and silane-epoxy reaction. This dual modification strategy reduces ITR at both filler-filler and filler-matrix interfaces, enabling the epoxy nanocomposite to achieve a thermal conductivity of 1.64 W (m·K)<sup>−1</sup> at 30 wt.% filler loading, representing an 811.1% improvement compared to neat epoxy. Furthermore, the BNNS-AgNPs@MPTS nanocomposite exhibits excellent electrical properties. Meanwhile, both experimental studies and simulations have demonstrated the promising potential of epoxy nanocomposites as high-performance thermal interface materials (TIMs).

One critical process in these applications is the precise patterning of LMs into desired shapes. Yet, existing LM patterning techniques predominantly focus on 2D patterns due to challenges posed by the inherent fluidity and leakage of LMs. Here, we introduce an approach that bypasses these limitations, enabling the creation of complex 3D leakage‐free LM structures. This is achieved through mechanical programming of 2D magnetically immobilized LM paste formed via incorporating magnetic particles into LMs. Such composite effectively resists leakage due to the combined effect of strong magnetic inter‐attraction within the porous magnetic networks and the high surface tension of LMs, while retaining the high conductivity. Diverse freestanding magnetic LM structures, obtained upon LM solidification at ambient temperature, dynamically morph between their 2D and various 3D configurations through multiple cycles of induction heating and magnetic‐assisted reprogramming, featuring large compression resistance and self‐healing capabilities. Potential applications of these leakage‐resistant, shape‐adaptable structures are demonstrated through a helical magnetic LM antenna, which showcases its efficiency in wireless communication and energy harvesting.","PeriodicalId":110,"journal":{"name":"Advanced Electronic Materials","volume":"20 1","pages":""},"PeriodicalIF":6.2,"publicationDate":"2025-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144701434","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}

Using a machine learning framework based on feature engineering, it is possible to accurately identify and classify distinctly pronounced letters from sensor outputs with an accuracy rate as high as 98%.
