We have witnessed the flourish of bioelectronics, brain–computer interface, and brain science programme in recent decades. In this review, up-to-date advances dielectric, piezoelectric, ferroelectric nanomaterials biomedical applications are summarised. Biomolecular detection methods been developed, including dielectric-gated field-effect transistor, dielectrophoresis, non-linear dielectric res...

We present the synthesis of ~250 nm thick K0.5Na0.5NbO3 thin films on platinized silicon substrates from alkoxide-based solutions with the stoichiometric composition and with the 5 or 10 mole % potassium acetate excess. The films crystallized into a pure perovskite phase, but depending on the amount of the alkali excess in solutions, they consisted of ~50 nm or of ~200 nm large grains. The fine...

The perovskites Pb(SclpNblp)O, and Pb(SclpTalp)O, can be obtained in a disordered state by means of a synthesis a t high temperature (1 250 to 1600 "C). Ordering of the trivalent and pentavalent ions occurs during annealing a t lower temperatures. The kinetics of this ordering process are investigated by means of X-ray diffraction, dielectric polarisation, and DSC measurements. The ordering pro...

The aim of this study is to propose simple and reliable techniques to assess the condition of metal oxide arrester based on the dielectric response techniques. A number of modern electrical diagnostics for Metal Oxide Surge Arrester (MOSA) are discussed in this paper. The techniques included return voltage, decay voltage and polarisation/depolarisation current measurement. The single and multip...

The definition for dielectric constant relates to the permittivity of the material (symbol use here ε). The permittivity expresses the ability of a material to polarise in response to an applied field. It is the ratio of the permittivity of the dielectric to the permittivity of a vacuum. Physically it means the greater the polarisation developed by a material in an applied field of given streng...

In this article, we analyse an integral equation of the second kind that represents solution N interacting dielectric spherical particles undergoing mutual polarisation. A traditional analysis can not quantify scaling stability constants- and thus approximation error- with respect to number involved spheres. We develop a new priori error demonstrates -independent continuous discrete formulation...

We study the microscopic basis of bistable switching of a confined liquid crystal via Monte Carlo simulations of hard pear-shaped particles. Using both dielectric and dipolar field couplings to this intrinsically flexoelectric fluid, it is shown that pulsed fields of opposing polarity can be used to switch between the vertical and hybrid aligned states. Further, it is shown that the field-susce...

Creation of correlated photon pairs is one the key topics in contemporary quantum optics. Here, we theoretically describe generation process spontaneous parametric down-conversion a resonant spherical nanoparticle made dielectric material with bulk $\chi^{(2)}$ nonlinearity. We pick size that satisfies condition eigenmodes described by Mie theory. reveal highly directional photon-pair can be ob...
