Theoretical studies on electrical conductance in nanostructures which consist of two semi-infinite leads separated by a typical molecular wire are carried out within Green's function (GF) formalism in the linear regime. For this reason, the GF of extended molecular wire is obtained. Hence, the electrical conductance of the system is derived theoretically, using the GF elements and wire ...

We report a simple method involving mechanical attrition followed by hot press sintering to fabricate tablet samples consisting of silver nanoparticles (Ag NPs) dispersed in luminescent silicon nanocrystal (Si NC) matrix. A dramatic increase in current by almost six orders of magnitude is observed for this type of Si NC-Ag NP hybrid nanocomposite compared with bare Si NC-based tablets. Collective ...

Conducting core-sheath nanofibres were prepared by the vapour-phase polymerisation of poly(3,4-ethylenedioxy thiophene) (PEDOT) on electrospun polyurethane (PU) nanofibres both with and without incorporating graphene nanoplatelets (GNPs) as the core part. The morphology, mechanical properties, electrical conductivity, and electroactive actuation of the core-sheath nanofibres were investigated. ...

This study assesses the suitability of developing a material for use in an experimental model of the carotid baroreceptors. Such a model could then be used in future studies to assess the impact of carotid artery stenting on hemodynamic stability. The material must exhibit a significant measurable electrical response to strain in a fashion analogous to baroreceptor behaviour. A modified ...

The Hybrid Sulphur (HyS) cycle has attracted much attention as a mass production process for hydrogen. It consists of an electrolysis step and a thermal decomposition one. In order to achieve high efficiency for hydrogen production and operational cost reduction, some developments in electrode materials with high corrosion resistance, high electrical conductivity and low anodic potential is a key ...

Electrical conductivity is a measure of the ability of a solution to cany* a current. Current flow in liquids differs from mat in metal conductors in that electrons cannot flow freely, but must be carried by ions. Ions are formed when a solid such as salt is dissolved in a liquid to form electrical components having opposite electrical charges. For example, sodium chloride separates to form Na" ...

The electrical properties of Bilirubin Rich Gallstone (BGS) were investigated by the Complex Impedance Spectroscopy (CIS) technique. The dielectric relaxation was found to be of non-Debye type. Evidences of temperature-dependent electrical relaxation phenomena as well as Negative Temperature Coefficient of Resistance (NTCR) character of the sample have been observed. The ac conductivity obeys the ...

A procedure based on electrical conductivity is described for measuring bentonite content in soil-bentonite mixtures having a wide range of bentonite contents. Standard equipment used for sedimentation analysis and an electrical conductivity meter are required. The procedure employs calibration curves relating electrical conductivity and bentonite concentration for soil-bentonite-water slurries. ...

The use of the dielectrophoresis as a tool for DNA manipulation is demonstrated experimentally, using both unmodified 48,500 base pairs long bacteriophage lambda dsDNA (λ-DNA), ∼16 μm in length and 414 base pairs long thiol modified natural dsDNA (avDNA), ∼140 nm in length. We show that both the dsDNA types used, are effectively directed between the planar gold electrodes by the positive ...

Operation Principle of Jiarun Eddy Current Separator Eddy current separators have a conveying belt with a rapidly rotating magnetic rotor in the drum. The high rotation speed of the magnets generates an induction field, producing a quickly alternating magnetic field. The separation is based on the principle that every electrically conductive particle located in an alternating ...
