Advanced Functional Materials, EarlyView.Geometry‐driven design of soft cellular metamaterials is systematically investigated by combining experiments, finite element modeling, and statistical prediction. The study quantifies how unit cell geometry and material properties govern stiffness, instability, densification, and energy absorption.

On the existence of nested orthogonal arrays
Discrete Mathematics, 2008 An orthogonal array \(\text{OA}(N,k,s,g)\) has \(N\) rows, \(k\) columns, \(s\) symbols, and strength \(g\) if it is an \(N \times k\) array with entries from an \(s\)-set in which every possible combination of symbols appear equally often as rows in every \(N \times g\) subarray.

Advanced Functional Materials, EarlyView.Ferroelectric nematic liquid crystals (FNLCs) offer fast, tunable polarization and low‐voltage operation but suffer from poor polarization retention at zero field. Semiconductor‐modified FNLCs enhance polarization retention and exhibit short‐ and long‐term electro‐optical responses, while also supporting spike‐type signal integrations.

Advanced Functional Materials, EarlyView.A systematic review is conducted to assess the influence of electrode architecture across micro‐ to mesoscopic length scales on electron‐transfer pathways in electrocatalysis. We discuss the structure‐activity relationships in electrocatalytic applications, including resource recovery and environmental remediation, and provide cost‐effective, efficient

Beyond the orthogonal array concept
European Journal of Combinatorics, 2004 The aim of this paper is to investigate a notion of regularity that is more flexible than the orthogonal array concept. A close connection is given between \(t\)-form spaces and \(T\)-designs in a Hamming space. The full \(t\)-distribution matrix, whose entries are special kinds of numbers, is also computed.

Advanced Functional Materials, EarlyView.Contrary to conventional expectations, the bulk photovoltaic effect in CuCrP2S6 is enhanced rather than suppressed upon transitioning into the crystallographically centrosymmetric phase. Dynamic Cu‐ion disorder creates transient polar states, which substantially amplifies zero‐bias photocurrent (shift‐current) generation, establishing dynamic symmetry ...
