An EZ${\mathcal {E}\mathcal {Z}}$‐structure for the mapping class group

open access: yesProceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.
Abstract We construct a boundary for the mapping class group Mod(S)${\rm Mod}(S)$ of a surface S$S$ of finite type. The action of Mod(S)${\rm Mod}(S)$ on this boundary is minimal, strongly proximal and topologically free. The boundary is the boundary of an EZ${\mathcal {E}\mathcal {Z}}$‐structure for Mod(S)${\rm Mod}(S)$.

Exploration of Pseudobinary Alloys (Al–Mn)‐(Co–Fe–Ni) to Design High‐Entropy and Compositionally Complex Alloys to Stabilize the τ Phase in Al–Mn‐Based Ferromagnetic Alloys

open access: yesAdvanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
This experimental study investigates the thermodynamic limits of the Al–Mn τ ferromagnetic phase within complex‐composition alloys (CCAs). Using nine rare‐earth‐free compositions, it explores a broad region of the pseudobinary AlMnCoFeNi system. The results reveal intricate links between composition, phase stability, and magnetic behavior, highlighting

Beyond Single‐Active Sites: The Emergence of High‐Entropy Perovskites in Energy and Environment Catalysis

open access: yesChemSusChem, Volume 19, Issue 13, 14 July 2026.
This review examines high‐entropy perovskites (HEPs) as a promising catalyst platform for energy and environmental applications. The focus is on configurational entropy engineering, design and synthesis, and computational understanding. These materials possess tunable active sites, enhanced stability, and improved electronic interactions, leading to ...
