Freestanding PZT Films for Integrated Wearable Sensing and Intelligent Acoustic Recognition

open access: yesAdvanced Science, EarlyView.
A freestanding epitaxial PZT/LaNiO3/Pt heterostructure is achieved via water‐assisted delamination from mica, effectively eliminating substrate‐induced clamping and releasing intrinsic ferroelectricity. The released film exhibits substantially enhanced remanent polarization and piezoelectric response, delivering excellent mechanical flexibility and ...

Non-asymptotic stability and consistency guarantees for physics-informed neural networks via coercive operator analysis

open access: yesCommunications in Nonlinear Science and Numerical Simulation
We present a unified theoretical framework for analyzing the stability and consistency of Physics-Informed Neural Networks (PINNs), grounded in operator coercivity, variational formulations, and non-asymptotic perturbation theory. PINNs approximate solutions to partial differential equations (PDEs) by minimizing residual losses over sampled collocation

Magnetic‐Field‐Tuned Spin‐Dependent D‐Band and Bifunctionality in L10‐FeCoPt for Enhanced Methanol Oxidation

open access: yesAdvanced Science, EarlyView.
The d‐band center and bifunctional mechanism jointly regulate the amounts of adsorbed OH* and CO*, thereby enhancing electrocatalytic performance, while the application of an external magnetic field further boosts this performance. ABSTRACT The spin‐dependent electronic structure of transition‐metal alloys plays a key role in tuning the magnetic‐field ...

Interfacial Asymmetry and Surface Roughness Enhanced Topological‐Hall‐Like Transport in SRO/BTO/SRO Trilayers

open access: yesAdvanced Science, EarlyView.
Trilayer oxide architecture introduces interfacial asymmetry and surface roughness in SRO/BTO/SRO heterostructures, creating a locally modulated polar and magnetic landscape. This design enhances the topological‐Hall‐like response, achieving a broad 5–90 K stability window and a maximum ρTHE of 0.8 µΩ cm, demonstrating an effective route to amplify ...

Magnetoelectric Multiferroics for the Next‐Generation Ultralow‐Power Electronics

open access: yesAdvanced Science, EarlyView.
Magnetoelectric coupling provides a unifying route from electric‐field control of magnetic order to non‐volatile MeRAM, MESO logic, and emerging antiferromagnetic and magnonic devices. By connecting switching physics with device benchmarks, material platforms, and integration strategies, distinctive technological opportunities are identified alongside ...

Police responses to coercive control

open access: yes, 2018
This project aimed to analyse police responses to domestic abuse cases since the introduction of the coercive control offence. This research provides a much-needed empirical evidence base on the impact of the new coercive control legislation in the ...

A Variational–Spectral Framework for Coercivity and Stability: L*L Structure and Geometric Applications

open access: yes
This work develops a general variational–spectral framework for functionals of the form   F(u) = ||R(u)||²,   where R is a nonlinear operator between Hilbert spaces and critical points are characterized by the condition R(u₀) = 0.   A fundamental structural identity shows that the second variation at a critical point is given by   Hess F(u₀ ...

Quantized Analog Inference Hardware Enabled by MoS2–Hf1‐xZrxO2 FeFET Synapses

open access: yesAdvanced Science, EarlyView.
A monolayer MoS2–HZO FeFET is presented as a pulse‐engineered neuromorphic device suitable for crossbar‐based analog computing. Programming‐pulse design enables tunable conductance trajectories for synaptic weight updates, while quantized machine‐learning approaches account for device variation, nonlinearity, and write noise, translating analog ...
