Physarum polycephalum slime mould can modify polyaniline (PANI) features due to its internal activity. We created networks with different conductivity made by the slime mould on PANI substrates. Thus, Physarum’s growth results in changing the conductivity state of PANI layers, providing negative and positive patterning of the samples. A spectrophotometric scanner is here exploited to investigat...

This work examines electro-thermal transport in silicon devices and in single-wall carbon nanotubes (SWNTs). Non-local transport is found to strongly affect heat generation in quasi-ballistic silicon devices. Under such conditions, Joule heat is mainly dissipated in the drain region, and increasing power densities may lead to phonon non-equilibrium. Significant current degradation is observed i...

In this Letter, we propose and experimentally demonstrate a simple method to provide additional information on the electro-mechanical properties of soils by electrical conductivity measurements. The AC electrical conductance of the soil is measured while it is exposed to a periodic vibration. The vibration-induced density fluctuation implies a corresponding conductivity fluctuation that can be ...

The effect of different plasticizers on the properties of PAN– polymer electrolytes has been studied. Propylene carbonate (PC) and ethylene carbonate (EC) having different values of donor numbers, dielectric constant and viscosity have been used as plasticizers. The highest room temperature conductivity for the film in the PAN– system was 3.04 × 10-4 S cm-1. The highest room temperature conduct...

The L-type Ca2+ channel or dihydropyridine receptor (DHPR) in vertebrate skeletal muscle is responsible for sensing sarcolemmal depolarizations and transducing this signal to the sarcoplasmic Ca2+ release channel RyR1 via conformational coupling to initiate muscle contraction. During this excitation-contraction (EC) coupling process there is a slow Ca2+ current through the mammalian DHPR which ...

The electrical conductivity (EC) of soil is generally measured after soil extraction, so this method cannot represent the in situ EC of soil (e.g., EC of soils with different moisture contents) and therefore lacks comparability in some cases. Using a resistance measurement apparatus converted from a configuration of soil microbial fuel cell, the in situ soil EC was evaluated according to the Oh...

The influence of the alkali resistant surfactant Dowfax 2A1 on single ion track etching in 30 lm polycarbonate foils is studied at low etch rate (5 M NaOH at 41.5 ± 2 C) using electro conductivity measurements. At surfactant concentrations above 10 4 vol.% breakthrough times are predictable (Dt/t < 0.25). At high surfactant concentrations (P0.1 vol.%) the formation of cylindrical channels is fa...

this paper is a preliminary communication of a study on removal and recovery of heavy metalsfrom industrial waste waters using electro-coagulation (ec) technique. the larger study envisages use of solarenergy for producing the d.c. current, and simple chemical methods of standard methods in chemistry like useof hydrochloric acid, hydrogen sulfide, collection of precipitate, incineration and get...

Milk electrical conductivity is employed for mastitis detection in cows due to its automation, low cost, and infection detectability at early stage. Nevertheless, the number of publications about its use in dairy goats is scarce. The aim of this study was to check and compare the detectability of goat mastitis (sensitivity and specificity) using different algorithms, constructed with individual...
