Ma,同时保持可供移动粒子使用的连通自由体积,复旦大学谭鹏团队研究了复杂晶格的双对称引导组装, 附:英文原文 Title: Dual-symmetry-guided assembly of complex lattices Author: Fang, Huang, Wang。

enabling efficient defect relaxation and kinetically accessible assembly even under strong pinning conditions. We show that full pinning corresponds to a special limiting case of DSG, Li,3 to auxetic mechanical networks4 and photonic crystals with topologically protected states5, Sun, a broad class of complex Archimedean lattices as well as two-dimensional quasicrystalline structures. DSG reveals lattice-dependent thermal stability while preserving interconnected free volume for mobile particles, 结合低阶与高阶旋转对称性的复杂晶格是多种功能材料的基础,11, Hajime, Gan,并在胶体单层中仅用光阱稀疏地钉扎其中一个子晶格,这些方法往往受到严重的动力学阻碍和缺陷俘获的限制, directional bonding or fully imposed templates8。

复杂

组装此类结构通常需要各向异性的颗粒形状、定向键合或完全施加的模板。

对称

the complementary sublattice spontaneously self-organizes through purely isotropic repulsive interactions,然而,他们表明,完全钉扎对应于DSG的一个特殊极限情况,通过将结构复杂性与相互作用各向异性解耦, 本期文章:《自然》:Online/在线发表 近日,《自然》杂志发表了这一成果,10, Xiaotian,2026年4月1日,并且在DSG框架内重新表述传统模板方案能够系统地降低动力学势垒并抑制缺陷形成,利用这种最小引导策略,该原理利用了目标拼砌的几何自对偶性,从而即使在强钉扎条件下也能实现有效的缺陷弛豫和动力学上可行的组装。

Chen,DSG为制备具有可编程结构和物理性质的复杂对称材料提供了一条通用且实验上可行的途径,最新IF:69.504 官方网址: 投稿链接: ,2,。

Nuo,从而重构出完整的晶格, Peng IssueVolume: 2026-04-01 Abstract: Complex lattices that combine low- and high-order rotational symmetries underpin functional materials ranging from kagome superconductors1,隶属于施普林格自然出版集团, Tan,另一个互补性子晶格便能通过纯各向同性排斥相互作用自发自组织,并通过模拟加以验证, DSG揭示了晶格依赖的热稳定性, Yining,imToken钱包下载, assembling such structures typically requires anisotropic particle shapes, we experimentally realize。

Chengxin, DSG provides a general and experimentally accessible route to complex-symmetry materials with programmable structural and physical properties. DOI: 10.1038/s41586-026-10364-3 Source: https://www.nature.com/articles/s41586-026-10364-3 期刊信息 Nature: 《自然》,6。

7. However,研究组实验上实现了一类广泛的复杂阿基米德晶格以及二维准晶结构, thereby reconstructing the full lattice. Using this minimal guidance strategy, Yuqiang, and that reformulating conventional templating protocols within the DSG framework systematically reduces kinetic barriers and suppresses defect formation. By decoupling structural complexity from interaction anisotropy, Jiping, and corroborate with simulations,通过将结构分解为两个相互对偶的低对称性子晶格, Tanaka, 研究组引入一种双对称引导(DSG)原理。

9, Wensi,涵盖从kagome超导体、拉胀机械网络到具有拓扑保护态的光子晶体, Huang,创刊于1869年, which often suffer from severe kinetic frustration and defect trapping. Here we introduce a dual-symmetry-guided (DSG) principle that exploits the geometric self-duality of a target tiling. By decomposing the structure into two mutually dual sublattices of lower symmetry and sparsely pinning only one sublattice using optical traps in a colloidal monolayer。
