Free‐Volume Regulation Enables Significantly Enhanced Electrical Breakdown via Short‐Chain Molecular Spatial‐Positioning Intercalation into Poly(vinylidene fluoride)

Advanced Science, EarlyView.
An innovative molecular spatial‐positioning shimming strategy is developed to optimize the electrical properties of poly(vinylidene fluoride) (PVDF). By intercalating polyethylene wax (PE wax) short‐chain molecules into PVDF's free volume, the film achieves a significantly enhanced energy density of 32.67 J cm−3.

Optimal tracking control for underactuated airship

Journal of Engineering and Applied Science
A non-linear mathematical model of underactuated airship is derived in this paper based on Euler-Newton approach. The model is linearized with small disturbance theory, producing a linear time varying (LTV) model.

Atomic‐Scale Mechanisms of Multi‐Resistance States in HfOx‐Based RRAM: Evolution of Atomic Electric Fields and Oxygen Vacancies

Advanced Science, EarlyView.
Atomic‐scale mechanisms governing multilevel resistive switching in HfOx‐based RRAM are reveal through advanced TEM. Thermally driven m‐phase rotation ([101]↔[011]) enables selective oxygen vacancy migration, which reconstructs atomic electric fields and dictates conduction—from Schottky/Poole‐Frenkel emission to Ohmic transport.

A Van der Waals Material Exhibiting Room Temperature Broken Inversion Symmetry with Ferroelectricity

Advanced Science, EarlyView.
This study reports a βp$\ubeta^{\text{p}}$ phase of indium selenide showing ferroelectricity over large areas at room temperature in a low‐dimensional limit. It is found that indium selenide films with βp$\ubeta^{\text{p}}$ layers display electric field‐induced switchable polarization characteristic of ferroelectric materials, suggesting the breaking ...

Gutmann Donor Theory‐Guided Design of Mononuclear Ionic Cluster for Exceptional N‐Type Thermoelectric Ionogel

Advanced Science, EarlyView.
Super‐stretchable and self‐healing polyacrylate ternary ionogel elastomers are used for flexible i‐TE devices. Based on Gutmann donor theory of doped anion, the work proposes a three‐parameter tuning strategy of flexible polymer‐doped anion‐synergistic cation to achieve the systematic design of ionic thermoelectric materials. Abstract Quasi‐solid‐state,

Migrasomes in Ischemic Stroke: Molecular Landscape and Pathophysiological Impact

Advanced Science, EarlyView.
Multi‐omics profiling of stroke patients exposes systemic molecular fingerprints of immune activation, oxidative stress and metabolic collapse. Complement and coagulation cascade, and cholesterol metabolism emerge as shared functional hallmarks of plasma migrasomes in stroke patients and migrasomes isolated from experimental stroke mice.
