Asymmetric Electrostrain/Electrobending in Piezoelectric Ceramics: Role of Defect Dipoles or Oxygen Vacancies

Advanced Science, EarlyView.
Defect‐configurational origins of the asymmetric apparent electrostrain are revealed in different piezoelectric ceramics via atomic‐scale visualization of defect configurations. Migration of oxygen vacancies leads to the electrobending effect in N2‐sintered BaTiO3, while defect dipoles in Ba0.99TiO2.99 generate true asymmetric electrostrain without ...

EPR Dosimetry in Recent Radiation Accident Cases

, 2008
The use of Electron Paramagnetic Resonance (EPR) for dosimetry is based on the capability of the technique specifically and sensitively to measure unpaired electron species and the fact that ionizing radiation creates such species in exact proportion to ...

Quantifying Magnetic Anisotropy of Ferroelectric Fe(II) Square‐Pyramidal Systems Using Torque Magnetometry

Advanced Science, EarlyView.
Five‐coordinate, square‐pyramidal Fe(II) complexes adopting polar, non‐centrosymmetric crystal structures exhibit exceptionally large easy‐axis magnetic anisotropy. Ligand‐driven distortions critically control the anisotropy, and the dielectric, Polarization vs Elecric field and piezo response studies confirm intrinsic polarization, positioning these ...

Interactive Simulation of CW and Pulsed EPR Spectra

, 2007
A general program for the computer simulation of cw electron paramagnetic resonance spectra has previously been developed [1]. This simulation package is currently being extended to include the simulation of pulsed EPR spectra.

Trap Depth Modulation and Antenna Effect of Organic Ligands for Enhancing Rare‐Earth Long Persistent Luminescence

Advanced Science, EarlyView.
Different from the current research trends that mainly focus on optimizing a single color system, a universal organic–inorganic hybrid strategy is proposed, aiming to synergistically enhance the luminescent properties of red, green, and blue multi‐color inorganic long‐persistent phosphorescent materials by trap depth modulation and antenna effect of ...

K+‐Triggered Defect Engineering and Proton‐Coupled Storage in V2O5·nH2O for Advanced Zn‐Ion Thin‐Film and Microbatteries

Advanced Science, EarlyView.
K+ pre‐intercalation in V2O5·nH2O induces interlayer contraction, oxygen‐vacancy formation, and mixed‐valence states, activating defect‐mediated proton‐dominated transport. This enables cooperative H+/Zn2+ storage with enhanced kinetics and stability. The resulting Zn‐based thin‐film and microbatteries deliver high areal energy and capacity, offering a

Atomic‐Level CuOx‐CoOx‐Pd Interfacial Engineering Enables Hierarchical Synergy for High‐Efficiency ORR Pathways and Boosted Power Output in Alkaline Fuel Cells

Advanced Science, EarlyView.
Atomically dispersed CuOx (CPCu‐1) forms isolated Cu–Ov sites that enable defect‐mediated O2 activation and fast electron/proton transfer via interfacial synergy. In contrast, thick CuOx clusters (CPCu‐10) promote a surface‐adsorption‐controlled pathway with intermediate accumulation, highlighting a mechanism switch from interfacial activation to ...
