Advanced Functional Materials, EarlyView.Ferroelectric nanoclusters create local internal fields in a normally non‐switchable polar film because of polarization mismatch at their interfaces. That field opposes polarization in the regions with larger polarization and reinforces polarization in the regions with smaller polarization.

On the creation of representative samples of random quasi-orders
Frontiers in Psychology, 2015 Dependencies between educational test items can be represented as quasi-orders on the item set of a knowledge domain and used for an efficient adaptive assessment of knowledge.

Observations on quasi-uniform products [PDF]
, 2007 We prove that any product of quotient maps in the category of quasi-uniform spaces and quasi-uniformly continuous maps is a quotient map. We also show that a quasi-uniformly continuous map from a product of quasi-uniform spaces into a quasi-pseudometric ...

Helical spin dynamics in commensurate magnets: A study on brochantite, Cu_{4}SO_{4}(OH)_{6}
Physical Review Research, 2023 We report the direct observation of a commensurate-ordered antiferromagnetic (AFM) state but incommensurate helical spin dynamics in the natural mineral brochantite Cu_{4}SO_{4}(OH)_{6} through neutron diffraction and neutron spectroscopy measurements ...

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

Advanced Functional Materials, EarlyView.A single‐step laser annealing strategy is presented for dual‐gate a‐IGZO TFTs. The steep thermal gradient induces graded oxygen doping in the channel and simultaneous WOx removal at the contacts, enabling concurrent interface and contact engineering.

Relations between generalized von Neumann-Jordan and James constants for quasi-Banach spaces
Journal of Inequalities and Applications, 2016 Let C N J ( B ) $\mathcal{C}_{NJ} ( \mathcal{B} )$ and J ( B ) $J ( \mathcal{B} )$ be the generalized von Neumann-Jordan and James constants of a quasi-Banach space B $\mathcal{B}$ , respectively.
