Historical Foundation and Practical Guideline for Ferroelectric Switching Kinetic Studies

Advanced Functional Materials, EarlyView.
The P and U pulses in the conventional PUND measurements are not identical because of the interplay between switching current and the measurement circuit components. This circuit effect can lead to a shift in polarization transients and misinterpreted physics in the switching kinetics.

On a Free Boundary Problem for thep-Laplacian

Journal of Mathematical Analysis and Applications, 1998
The author considers the problem \[ \text{div} \bigl(| Du |^{p-2}Du \bigr) =0\quad\text{in}\quad\Omega_0- \Omega_1, \] \(u\to 1\), \(Du\to c_1\) uniformly a.e. as \(x\to \partial \Omega_1\), \(u\to 0\), \(Du\to c_0\) uniformly a.e. as \(x\to \partial\Omega_0\), where \(\Omega_1 \) and \(\Omega_0\) are bounded connected domains, \(\Omega_1 \subset ...

Long‐Range Coordination Environment Modulates Single‐Atom Local States and Systemic Impact on CO2 Photoconversion

Advanced Functional Materials, EarlyView.
Terminal groups on Cu porphyrins modulate the electronic states of single‐atom Cu centers through a long‐range electronic effect, without altering the Cu coordination geometry. Meanwhile, a multi‐descriptor framework is established that incorporates porphyrin regulation, hybrid catalyst properties, and CO2 photoreduction capabilities.

Ultrasmall High‐Entropy Materials: Nanoscale Effects, Synthesis, and Mechanistic Insights

Advanced Functional Materials, EarlyView.
This review article focuses on sub‐10 nm high‐entropy materials that combine nanoscale design with complex compositions for next‐generation applications. ABSTRACT Ultrasmall high‐entropy nanomaterials (USHENMs, <10 nm) merge multicomponent chemistry with size‐dependent effects, forming a distinct class of materials with unprecedented properties.

Powering Nanocrystal‐Based Heat Engines With Light‐Emitting Metasurfaces That Influence Their Temperature

Advanced Functional Materials, EarlyView.
Metasurfaces and other structured photonic environments can dramatically modify the absorption and/or light emission of semiconductors. However, the consequences of these changes on the temperature of the system are not well understood. The authors address this problem for colloidal nanocrystals and leverage their findings to convert light into ...

Bioinspired Mechanically Robust Organic–Inorganic Hybridized Bio‐Adhesives With up to 50% Inorganic Components by Bi‐Continuous Phase Engineering

Advanced Functional Materials, EarlyView.
A robust plant protein adhesive was prepared by fabricating a bi‐continuous organic–inorganic hybrid structure. Compared with traditional organic–inorganic hybrid adhesives, the addition amount of inorganic phase is increased from 0.2%–3.0% to 50%, and the strength and toughness are increased by 6 and 121 times, respectively.

On the tidal motion around the earth complicated by the circular geometry of the ocean's shape

Electronic Journal of Differential Equations, 2000
We study the Cauchy-Poisson free boundary problem on the stationary motion of a perfect incompressible fluid circulating around the Earth. The main goal is to find the inverse conformal mapping of the unknown free boundary in the hodograph plane onto ...

On well-posedness of the free boundary problem for ideal compressible MHD equations and Maxwell equations in vacuum

Современная математика: Фундаментальные направления
We survey results on the well-posedness of the free interface problem when an interface separates a perfectly conducting inviscid fluid (e.g., plasma) from a vacuum.
