Ultrahigh Energy-Storage Density of BaTiO3‑Based Ceramics via the Interfacial Polarization Strategy
, 2023 Lead-free dielectric capacitors are excellent candidates for pulsed power devices. However, their low breakdown strength (Eb) strongly limits their energy-storage performance.

Interfacial Polar Interactions Affect Gramicidin Channel Kinetics [PDF]
Biophysical Journal, 2008 Critical to biological processes such as secretion and transport, protein-lipid interactions within the membrane and at the membrane-water interface still raise many questions. Here we examine the role of lipid headgroups in these interactions by using gramicidin A (gA) channels in planar bilayers as a probe.

An Electrochemical Impedance Study of AISI 321 Stainless Steel in 0.5 M H2SO4
International Journal of Electrochemistry, 2011 The electrochemical behavior of passive films formed on AISI 321 has been examined using electrochemical impedance spectroscopy. AISI 321 is characterized by high interfacial impedance, thereby illustrating its high corrosion resistance.

A fractional stochastic theory for interfacial polarization of cell aggregates
CoRR, 2020 We present a theoretical framework to model the electric response of cell aggregates. We establish a coarse representation for each cell as a combination of membrane and cytoplasm dipole moments. Then we compute the effective conductivity of the resulting system, and thereafter derive a Fokker-Planck partial differential equation that captures the time-

Interfacial Polarization-Dominated Dielectric Loss in SnO2@rGO Electromagnetic Wave Absorbers
Metals, 2022 Interfacial polarization is generally a major cause of dielectric loss, but its exact contribution to the electromagnetic wave (EMW) absorption capacity of absorbers remains to be elucidated.

Polarization enhancement in short period superlattices via interfacial intermixing
, 2007 The effect of intermixing at the interface of short period PbTiO3 SrTiO3 superlattices is studied using first-principles density functional theory. The results indicate that interfacial intermixing significantly enhances the polarization within the ...

Molecules, 2021 In this paper, we will discuss the excellent broadband microwave absorption behaviors of Cu/CuO/carbon nanosheet composites: traces of copper and oxide embedded in a carbon nano-sheet not only cut down the high permittivity of adsorbs but also induce ...

Polarization Saturation in Multilayered Interfacial Ferroelectrics
Advanced MaterialsAbstractVan der Waals polytypes of broken inversion and mirror symmetries have been recently shown to exhibit switchable electric polarization even at the ultimate two‐layer thin limit. Their out‐of‐plane polarization has been found to accumulate in a ladder‐like fashion with each successive layer, offering 2D building blocks for the bottom‐up ...
