Volcano-like relation between surface confinement and heat generated in electrical double layers

Computational Materials Today
Electrical double layer (EDL) formation generates heat; however, the underlying mechanisms remain poorly understood, particularly under surface confinement.

Monitoring the interfacial polarization parameters of transformers insulation for the assessment of ageing condition of transformer

, 1994
Interfacial polarization spectra (IPS) has been investigated for the assessment of the condition of insulation in aged transformers. The measurement technique with some special reference to distribution transformers is discussed in detail in this paper ...

The influence of an extrinsic interfacial layer on the polarization of sputtered BaTiO3 film [PDF]

, 2005
As an origin of degradation of remnant polarization in Pt/BaTiO33/Pt capacitor structure, an interfacial layer formed at the interface of BaTiO (film and a Pt bottom electrode is considered.

Electrospun Wood‐Derived Biopolymers as Electrodes in Electrochemical Energy Storage Technologies

Advanced Functional Materials, EarlyView.
Electrospinning transforms wood‐derived cellulose and lignin into architecturally defined, binder‐free carbon electrodes with tuneable porosity and functionality. This review shows how fibre design enables decoupled charge and mass transport, enhancing performance across battery systems, while identifying key challenges in spinnability, scalability ...

Multimodal Optoelectronic Synapses for Neuromorphic Intelligence: Coupling Light, Electrical, Thermal, and Beyond

Advanced Functional Materials, EarlyView.
This review revisits optoelectronic neuromorphic devices that extend from unimodal sensing toward multimodal perception. Five types of stimuli‐to‐output information flow that are classified based on the device roles within the system and applications are summarized and discussed.

Demo 24-07 Polarization by Scattering

, 2001
Light is polarized when it scatters from materials like air or water. This demonstration shows some of the properties of this polarization, using the apparatus of Figure 1, in which the light beam passes through a water tank into which a small amount ...

Polarization-induced interfacial coupling modulations in BaTiO3/GaN heterojunction devices

, 2017
We report on the ferroelectric polarization-induced switchable interfacial coupling modulations in BaTiO3/GaN heterojunction transport behaviour. The ferroelectric barium titanate, BaTiO3 (BTO) was integrated with polar semiconductor gallium nitride (GaN)

Strong Lead‐Free Bioinspired Piezoceramics for Durable Energy Transducers

Advanced Functional Materials, EarlyView.
We fabricated brick‐and‐mortar lead‐free piezoceramics with Bi0.5Na0.5TiO3 monocrystal platelets as bricks and amorphous silica as mortar. The alignment of the bricks and the presence of the amorphous silica led to anisotropic residual stresses. These residual stresses increase the samples toughness, strength and durability while the brick alignment ...

Enhanced superconductivity and coexisting ferroelectricity at oxide interfaces

Nature Communications
The coexistence of superconductivity and ferroelectricity is rare due to their conflicting requirements: superconductivity relies on free charge carriers, whereas ferroelectricity typically occurs in insulating systems.

Visualization of interfacial adhesive defects at dental restorations with spectral domain and polarization sensitive optical coherence tomography

Current Directions in Biomedical Engineering, 2018
Restoration loss based on interfacial adhesive defects and associated caries at the restoration margin are the main causes for invasive replacement of dental restorations.
