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.

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.

Dual Optical Hyperbolicity of PdCoO2 and PdCrO2 Delafossite Single Crystals
Advanced Functional Materials, EarlyView.In this work, the hyperbolic response of PdCoO₂ and PdCrO₂ delafossites is investigated for the first time. They exhibit dual hyperbolic regimes, one localized around a phonon absorption in the mid‐infrared spectral region, and the other extending into the visible range.

Peak‐in‐Valley Metal Nano‐Architectures via E‐Beam‐Guided Metal Oxide Redox
Advanced Functional Materials, EarlyView.Focused electron beam irradiation of nanoelectrosprayed water‐ammonia films enables the synthesis of topologically complex metal nanostructures via solvent‐mediated metal/metal‐ion redox control. Low ammonia favors radiolytic oxidation, etching copper.
