Research

Atoms are the smallest building blocks of matter. Under the basic quantized physical and chemical framework, through the guidance of atoms in the preparation process, it is theoretically possible to prepare new materials, construct efficient devices and create advanced systems. This is a kind of extreme atomic scale manufacturing technology, namely atomic fabrication. Atomic fabrication enables the customization of the structure and properties of materials on demand, which will promote technological change in the field of material science.

    Guanghui Cao#, Jingjing Liang#, Zenglong Guo#, Kenan Yang#, Gang Wang, Huiliu Wang, Xuhao Wan, Zeyuan Li, Yijia Bai, Yile Zhang, Junlin Liu, Yanpeng Feng, Zhenying Zheng, Cai Lu, Guangzhi He, Zeyou Xiong, Ze Liu, Shengli Chen, Yuzheng Guo*, Mengqi Zeng*, Junhao Lin*, Lei Fu* First Pubulished: 14 June 2023

    High-entropy alloy nanoparticles (HEA-NPs) show great potential as functional materials. However, thus far, the realized high-entropy alloys have been restricted to palettes of similar elements, which greatly hinders the material design, property optimization and mechanistic exploration for different applications. Herein, we discovered that liquid metal endowing negative mixing enthalpy with other elements could provide a stable thermodynamic condition and act as a desirable dynamic mixing reservoir, thus realizing the synthesis of HEA-NPs with a diverse range of metal elements in mild reaction conditions. The involved elements have a wide range of atomic radii and melting points. We also realized the precisely fabricated structures of nanoparticles via mixing enthalpy tuning.

    First Pubulished: 5 March 2024

    The self-lattice-framework with mixing assistor guided strategy was proposed for synthesizing ultrathin high-entropy oxides with the desired phase structures. Natural bonding preference constructed the basis of the lattice framework, and the Ga assistor promoted multiple elements into the lattice site to form the high-entropy state. The glucose and glycine were utilized to generate the carbon template for guiding the morphology. This work lays the foundation for applications of high-entropy oxides and inspires a similar methodology to explore high-entropy compounds.

    We report a material system that differentiates from layered and non-layered materials, termed quasi-layered domino-structured (QLDS) materials, effectively bridging the gap between these two typical categories. Considering the skewed structure, the force orthogonal to the 2D QLDS-GaTe growth plane constitutes a synergistic blend of vdW forces and covalent bonds, with neither of them being perpendicular to the 2D growth plane. This unique amalgamation results in a force that surpasses that in layered materials, yet is weaker than that in non-layered materials.
