On incomplete orthogonal arrays

open access: yesJournal of Combinatorial Theory, Series A, 1985
\textit{E. T. Parker} [Proc. Am. Math. Soc. 13, 219-221 (1962; Zbl 0105.015)] remarked that if an incomplete orthogonal array with parameters (1,r,s,k,2) exists then \(s\geq (r-1)k\). As the author shows, this result is easily extended to incomplete orthogonal arrays (1,r,s,k,t) for which \(s\geq (r-t+1)k\). \textit{K. A. Bush} [Ann. Math.

Azaporphyrinoid‐Based Photo‐ and Electroactive Architectures for Advanced Functional Materials

open access: yesAdvanced Materials, EarlyView.
A long‐standing collaboration between the Torres and Guldi groups has yielded diverse azaporphyrinoid‐based donor‐acceptor nanohybrids with promising applications in solar energy conversion. This conspectus highlights key molecular platforms and structure‐function relationships that govern light and charge management, supporting the rational design of ...

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

open access: yesAdvanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Observation of Dislocation Bound States and Skin Effects in Non‐Hermitian Chern Insulators

open access: yesAdvanced Materials, EarlyView.
Experimental observation of the dislocation‐induced bound states and skin effects is demonstrated in a line‐gap non‐Hermitian acoustic lattice. By utilizing active meta‐atoms to measure the full complex spectrum and biorthogonal eigenstates, the study reveals the exceptional‐point‐driven melting of defect modes.
