Improved energy storage property in polyvinylidene fluoride‐based multilayered composite regulated by oriented carbon nanotube@SiO2 nanowires

open access: yesIET Nanodielectrics, 2023
High‐performance dielectric capacitors are essential components of advanced electronic and pulsed power systems for energy storage. Because of their high breakdown strength and excellent flexibility, polymer‐based capacitors are regarded as auspicious ...

An improved formulation of Jaccard's theory of the electric properties of ice

open access: yes, 2018
In the standard derivation of Jaccard's theory of the electric properties of ice, no fundamental distinction is made between bound and free charges.

Transport theory and low energy properties of colour superconductors [PDF]

open access: yes, 2001
The one-loop polarisation tensor and the propagation of ``in-medium'' photons of colour superconductors in the 2SC and CFL phase is discussed. For a study of thermal corrections to the low energy effective theory in the 2SC phase, a classical transport ...

3D‐Printable Near‐Infrared‐Responsive Microscale Cantilever made of the Composite Consisting of Ceramic Particles and Graphene Flakes

open access: yesAdvanced Engineering Materials, EarlyView.
A near infrared‐responsive microscale cantilever is developed using a 3D‐printable composite based on photocurable resin consisting of sepiolite and graphene flakes. The material absorbs 1064 nm light, causing shape transformation with an average displacement of 1.3 mm in 1.7 s. Displacement is measured via video recording.

Measurements of electric properties using an open-ended probe blocked by a non-conducting foil

open access: yesResults in Physics, 2016
An open-ended coaxial probe separated from the investigated medium by a thin non-conducting layer (foil) is proposed for making dielectric permittivity measurements within the RF range.

The effect of nitrogen ion implantation on the physical and dielectric properties of cobalt-doped PZT ceramics

open access: yesResults in Physics, 2020
Cobalt-doped PZT ceramics (Pb(Zr0.52Ti0.48)1-xCoxO3, where x = 0.005, 0.010, 0.015 and 0.02, were implanted by nitrogen ions at 70 keV with fluences of 1 × 1017 and 5 × 1017 ions/cm2.

Ultrasensitive and fast single wavelength plasmonic hydrogen sensing with anisotropic nanostructured Pd films

open access: yes, 2018
Anisotropic nanostructured porous Pd films are fabricated using oblique angle deposition in vacuum on a glass substrate. They display a dichroic response, due to localised surface plasmon resonances (LSPR) within the nanoparticles forming the film ...

Strain Gradients in Epitaxial Ferroelectrics [PDF]

open access: yes, 2004
X-ray analysis of ferroelectric thin layers of Ba1/2Sr1/2TiO3 with different thickness reveals the presence of internal strain gradients across the film thickness and allows us to propose a functional form for the internal strain profile.

Effects of electrothermal ageing on dielectric performance of metallised biaxial orientation polypropylene film capacitors in strong magnetic fields

open access: yesHigh Voltage
The dielectric performance of the pristine and the electrothermal‐aged metallised polypropylene capacitors are investigated under different magnetic fields. The energy storage capacity decreases under the magnetic field. At 12 T, the capacitance value of
