Synthetic Active Liquid Crystals Powered by Acoustic Waves
Advanced Materials, EarlyView.A fully synthetic active liquid crystal, energized by an acoustic field, is presented. This system exhibits active nematic behavior, tunable topological defect dynamics, and persistent hydrodynamic vortices at high activity levels. The material maintains stable properties while enabling precise activity control in a wide range.

General Topology and its Applications, 1973 AbstractIn this paper, a shape category having all topological spaces for objects is constructed and axiomatically characterized. Spaces which are isomorphic objects in this category are said to be of the same shape. An axiomatic characterization of the full subcategory or the shape category having all Hansdorff compact spaces for objects is also given.

1D Magnetic Topological Inorganic Electrides
Advanced Materials, EarlyView.A series of 1D stable magnetic inorganic electrides are identified by high throughput screening and experimental synthesis. Furthermore, these 1D inorganic electrides exhibit various applications, including spintronics, topological electronics, low work function, electron emission, and high‐performance catalysts for NH3 reductions.

Topology of Misorientation Spaces
Proceedings of the Steklov Institute of MathematicsLet $G_1$ and $G_2$ be discrete subgroups of $SO(3)$. The double quotients of the form $X(G_1,G_2)=G_1\backslash SO(3)/G_2$ were introduced in material science under the name misorientation spaces. In this paper we review several known results that allow to study topology of misorientation spaces.

Non‐Hermitian Boundary in a Surface Selective Reconstructed Magnetic Weyl Semimetal
Advanced Materials, EarlyView.This study is the first to propose that the surface reconstruction of a Weyl semimetal creates a Hermitian bulk‐non‐Hermitian boundary system. The non‐Hermitian effects arising from the surface reconstruction are manifested by the emergence of non‐topological surface Fermi arcs (NTSFAs) and the broadening of both topological surface Fermi arcs (SFAs ...
