Locking Metastable Topological Domains in Nematic Liquid Crystal Pi Cells
Advanced Functional Materials, EarlyView.Selective photopolymerization in the presence of a controlled voltage defines permanent director walls that lock‐in metastable bend and twist configurations within nematic liquid crystal Pi cells. Q‐tensor simulations corroborate the experiments, demonstrating the topological state stabilization.

Direct Evidence of Topological Dirac Fermions in a Low Carrier Density Correlated 5d Oxide
Advanced Functional Materials, EarlyView.The 5d oxide BiRe2O6 is discovered as a low‐carrier‐density topological semimetal hosting symmetry‐protected Dirac fermions stabilized by nonsymmorphic symmetries. Angle‐resolved photoemission spectroscopy, quantum oscillations, and magnetotransport measurements reveal gapless Dirac cones, quasi‐2D Fermi surfaces, high carrier mobility, and a field ...

Advanced Functional Materials, EarlyView.Block copolymer microcapsules with ultrathin, perpendicularly perforated membranes are developed through double emulsions, initiated by the diffusion of water into single emulsions. Both shell thickness and channel diameter can be systematically tuned, offering precision in molecular sieving and significantly enhanced permeation rates.

Analytic torsion forms and torsion-signature
, 1996 Local families index theorems have revealed a rich context in which to place nonlocal spectral invariants such as the eta invariant and analytic torsion. The index theorem for families of Dirac operators on manifolds with boundary involves the eta invariant as the degree-zero component of an ``eta differential form'' on the base.

Confinement Driven Spin‐Texture Evolution in Directly Written Nanomagnets
Advanced Functional Materials, EarlyView.Spin‐texture is directly written by triggering lattice ordering locally at the nanoscale. Geometric confinement drives the formation of spin‐textures such as Néel walls with perpendicular core spins, essential for technological applications. Abstract In low‐dimensional magnetic structures, magnetostatic energy minimization yields a uniform spin‐texture,
