Chemically Processed Porous V2O5 Thin‐Film Cathodes for High‐Performance Thin‐film Zn‐Ion Batteries
Advanced Functional Materials, Volume 35, Issue 12, March 18, 2025.This study presents a rapid, cost‐effective chemical method for fabricating porous vanadium oxide thin‐film cathodes, aimed at enhancing charge storage in Zinc‐ion thin‐film batteries. The approach promises high‐performance, safe, and affordable thin‐film batteries, with industrial viability through efficient processing of highly porous cathodes ...

, 1991 A relatively obscure eigenvalue inequality due to Wielandt is used to give a simple derivation of the asymptotic distribution of the eigenvalues of a random symmetric matrix. The asymptotic distributions are obtained under a fairly general setting.

Universal Superconductivity in FeTe and All‐Iron‐Based Ferromagnetic Superconductor Heterostructures
Advanced Functional Materials, EarlyView.The first all‐iron‐based ferromagnetic superconductor heterostructures with high‐temperature superconductivity and strong ferromagnetism aredemonstrated. From this, it is discovered that FeTe becomes universallysuperconducting with a minute level of cationic impurities through doping ordiffusion from neighboring layers, suggesting its ground state can ...

Print‐and‐Plate Architected Electrodes for Electrochemical Transformations Under Flow
Advanced Functional Materials, EarlyView.Typical flow cell electrodes are composed of stochastic porous carbon, limiting understanding of electrode structure‐performance relationships. This work describes an approach, termed “print‐and‐plate,” to prepare porous electrodes by direct ink writing followed by conformal metal coating.

Symmetry Feature and Construction for the 3-Band Tight Framelets with Prescribed Properties
Journal of Applied Mathematics, 2012 A construction approach for the 3-band tight wavelet frames by factorization of paraunitary matrix is developed. Several necessary constraints on the filter lengths and symmetric features of wavelet frames are investigated starting at the constructed ...

Symmetric schemes for computing the minimum eigenvalue of a symmetric Toeplitz matrix [PDF]
Linear Algebra and its Applications, 1999 In [8] and [9] W. Mackens and the present author presented two generalizations of a method of Cybenko and Van Loan [4] for computing the smallest eigenvalue of a symmetric, positive definite Toeplitz matrix. Taking advantage of the symmetry or skew-symmetry of the corresponding eigenvector both methods are improved considerably.

Advanced Functional Materials, EarlyView.The plasma edge of transparent conducting oxide SrNbO3 shifts from ∼2 eV in the visible range to 1.37 eV in the near‐infrared region by off‐stoichiometry using the vacancy sites as quasi‐substitutional virtual elements. This work advances the stoichiometry engineering of perovskite oxides using oxide molecular beam epitaxy, allowing synthesis beyond ...
