Silicon nanowire (SiNW) based thermoelectric device (TED) has potential applications in areas such as chip level cooling/ energy harvesting. It is a great challenge however, to assemble an efficient device with these SiNW. The presence of parasitic in the form of interfacial electrical resistance will have a significant impact on the performance of the TED. In this work, we explore the effect o...

background: with increasing age, some changes appeared in specifications of vessels which including dimensions and elasticity in their. the changes in parameters such as resistance, inertance and compliance vessels appear and eventually changes in the environmental pulse releases are in circulation. these changes clearly appear in specification of photoplethysmogram particularly in the size and...

conventional and nanostructured ysz coatings were deposited on the in-738 ni super alloy by the atmospheric plasma spray technique. the oxidation was measured at 1100°c in an atmospheric electrical furnace. according to the experimental results the nanostructured coatings showed a better oxidation resistance than the conventional ones. the improved oxidation resistance of the nanocoating could ...

The electrical potential difference and electrical resistance of the nonswelling cornea of the dogfish, Squalus acanthias, were examined. It was found that routine procedures used in the procurement of fish invariably produce damage to the corneal epithelium which affects electrical measurements and possibly composition of the aqueous humor. We found no electrical evidence of ionic pumps in the...

1. BASIC THEORY The electrical conductivity of a metal depends on the movement of electrons through its crystal lattice. Due to thermal excitation, the electrical resistance of a conductor varies according to its temperature and this forms the basic principals of resistance thermometry. The effect is most commonly exhibited as an increase in resistance with increasing temperature, a positive te...

Heat transfer is a critical aspect related to Electrical machine design. To insure a successful design of the electrical machine, special attention has to be given to thermal aspects in parallel with the traditional Electromagnetic design. For calculating the temperature rise in electrical systems such as electrical machines or power electronic systems it is important to measure the temperature...

One of the fundamental principles of neuroscience is that direct electrical interactions between neurons are not possible without specialized electrical contacts, gap junctions, because the transmembrane resistance of neurons is typically much higher than the resistance of the adjacent extracellular space. However it has been proposed that in the retina direct electrical interactions between co...
