Operando Tracking of Oxygen‐Vacancy Dynamics and Negative Capacitance in Ca‐Doped BiFeO3

open access: yesAdvanced Functional Materials, EarlyView.
Operando electrochemical impedance spectroscopy, combined with electrocoloration, enables a direct correlation between real‐space ionic redistribution and the corresponding frequency‐domain electrical response. In lateral Ca‐doped BiFeO3 devices, time‐resolved impedance snapshots capture the evolution from bulk‐dominated mixed conduction to an ...

Spatial Mismatch or Racial Mismatch? [PDF]

open access: yes
We contrast the spatial mismatch hypothesis with what we term the racial mismatch hypothesis – that the problem is not a lack of jobs, per se, where blacks live, but a lack of jobs where blacks live into which blacks are hired.

Atom Probe Tomography as an Emerging Tool for Understanding Defect‑Driven Mechanisms in HfO2‑Based Ferroelectrics

open access: yesAdvanced Functional Materials, EarlyView.
This Perspective highlights atom probe tomography as a powerful tool for understanding the atomic‐scale defect chemistry in HfO2‐based ferroelectrics. 3D mapping of dopants, point defects, and interface chemistry can provide new insight into defect‐driven mechanisms underpinning the ferroelectricity in the system and guide the design of more reliable ...

Power enhancement of PV arrays in different configurations under different partial shaded condition

open access: yesScientific Reports
Among the most sustainable forms of energy, solar energy delivers clean, dependable, and limitless power. However, the PV arrays experience uneven irradiance as a result of partial shadowing situations, which causes several peaks in their PV ...

On the Measurement of Mismatch [PDF]

open access: yes
This paper introduces and examines a definition of an equilibrium rate of unemployment that can be used as mismatch indicator, too. In contrast to existing indicators this measurement method is based directly on the Beveridge-Curve. An application of the

Gradient‐Conductivity Architecture Enables Synchronous Enhancement of Sensitivity and Detection Range in Multifunctional All‐Paper Sensors

open access: yesAdvanced Functional Materials, EarlyView.
A gradient‐engineered all‐paper sensor is fabricated by integrating MXene and in situ grown AgNPs within hierarchical cellulose networks. The device breaks the sensitivity–detection range trade‐off through cascaded conductive pathways, enabling ultrahigh pressure sensitivity, humidity–pressure decoupled dual‐mode sensing, and outstanding EMI shielding,

Benefattori dall’aldilà: i lasciti per i lavori edilizi di pubblica utilità a Bologna (secoli XIII e XIV)

open access: yes, 2021
La trattazione riguarda i benefattori, i donatori che hanno deciso a Bologna di contribuire al bene comune non tramite le tradizionali istituzioni caritatevoli, quali ospedali, conventi e monasteri, ma anche attraverso l’investimento dei loro beni nel ...

Programmable Soft Actuator with Multi‐Responsiveness Based on Conductive MOF‐Liquid Crystal Polymer Composite

open access: yesAdvanced Functional Materials, EarlyView.
A sequential dual‐alignment strategy independently programs the orientation of conductive metal‐organic framework (c‐MOF) microrods and liquid crystals within a composite film. This approach creates an asymmetric bilayer structure that enables precise, multi‐responsive actuation.

DO AGGREGATE MEASURES OF MISMATCH MEASURE MISMATCH?A TIME SERIES ANALYSIS OF EXISTING CONCEPTS [PDF]

open access: yes
This paper discusses the performance of popular mismatch indexes proposed by Lilien (1982), Jackman and Roper (1987), Jackman, Layard and Savouri (1991), and Lambert (1988).

Enhanced Ferroelectric Phase Formation via Local Structure Modification in the Pre‐Crystalline State of Hafnium Zirconium Oxide Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
Hafnium zirconium oxide thin films are grown using plasma‐enhanced atomic layer deposition with the addition of an atomic layer annealing (ALA) step. ALA leads to a change in the short‐range structure of the deposit and encourages formation of the ferroelectric Pca21 phase. The result is wake‐up‐free performance with films exposed to ALA.
