Wake‐Up and Fatigue under Electrical Cycling in HfO2‐Based Ferroelectrics: Mechanisms and Strategies toward Reliable Devices

open access: yesAdvanced Science, EarlyView.
HfO2‐based ferroelectrics exhibit wake‐up and fatigue behaviors during electrical cycling, significantly affecting device endurance and reliability. These phenomena are governed by defect dynamics, including oxygen vacancy redistribution and charge trapping.

Derived equivalences of upper-triangular ring spectra via lax limits

open access: yesComptes Rendus. Mathématique
We extend a theorem of Ladkani concerning derived equivalences between upper-triangular matrix rings to ring spectra. Our result also extends an analogous theorem of Maycock for differential graded algebras.

Polynomial functions on upper triangular matrix algebras [PDF]

open access: yesMonatshefte für Mathematik, 2016
There are two kinds of polynomial functions on matrix algebras over commutative rings: those induced by polynomials with coefficients in the algebra itself and those induced by polynomials with scalar coefficients. In the case of algebras of upper triangular matrices over a commutative ring, we characterize the former in terms of the latter (which are ...

Automorphism groups of generalized triangular matrix rings [PDF]

open access: yes, 2011
We call a ring strongly indecomposable if it cannot be represented as a non-trivial (i.e. M≠0) generalized triangular matrix ring RM0S, for some rings R and S and some R-S-bimodule RMS.

The Plant‐to‐Plant Circular Strategy: Coupling Photodegradation and Phytoremediation With Plant‐Based Nanomaterials for Plastic Degradation

open access: yesAdvanced Science, EarlyView.
Plant‐based nanomaterials derived from alfalfa serve as dual‐function catalysts, coupling photodegradation and phytoremediation to degrade polyethylene under UV‐A light and in soil. The nanomaterials work synergistically with alfalfa and soil microbes, achieving efficient plastic breakdown without trophic transfer.

On a generalized Jordan normal form of an infinite upper triangular matrix

open access: yes, 2019
Any square matrix over an algebraically closed field has a Jordan normal form. In this paper, we prove that every infinite upper triangular matrix over an arbitrary field has a generalized infinite Jordan normal ...

Transparent Topological Meta‐Diplexer via Tightly Confined Valley Surface States

open access: yesAdvanced Science, EarlyView.
An optically transparent topological metasurface supporting tightly confined valley surface states enables robust and flexible wave routing in an ultrathin platform. A compact transparent meta‐diplexer with spatially and spectrally separated channels is realized, while communication experiments verify high‐fidelity signal transmission, opening new ...

Belitskii's canonical forms of upper triangular nilpotent matrices under upper triangular similarity

open access: yes, 2016
All indecomposable canonical forms are determined for upper triangular nilpotent matrices of size less than or equal to 7 under upper triangular similarity via Belitskii's algorithm. Furthermore, we show that there exists an indecomposable canonical form

Revealing the Underlying Mechanisms in Performance Enhancement of Shellular Lattice Electrodes During Anion Exchange Membrane Water Electrolysis Process

open access: yesAdvanced Science, EarlyView.
Micro laser powder bed fusion enables architected nickel shellular lattice gas diffusion layers for anion exchange membrane water electrolysis. Among regular open cell geometries, the Gyroid lattice promotes bubble release, convective reactant replenishment and continuous electron transport, delivering low overpotentials, enhanced charge transfer and ...

A Unified Approach to Generalizing π-Extending and π-Baer Rings

open access: yesJournal of Mathematics
This paper introduces and examines the right essentially π-Baer ring property, which serves as a new extension of the π-extending and π-Baer ring conditions. The initial phase of the study involves the development of several foundational results.
