Thermal Conductivity of Carbon Nanotubes and their Polymer Nanocomposites: A Review [PDF]

open access: yes, 2011
Thermally conductive polymer composites offer new possibilities for replacing metal parts in several applications, including power electronics, electric motors and generators, heat exchangers, etc., thanks to the polymer advantages such as light weight ...

Series, index and threshold for random 2D composite

open access: yesArchives of Mechanics, 2015
Effective conductivity of a 2D random composite is expressed in the form of long series in the volume fraction of ideally conducting disks. The problem of a direct reconstruction of the critical index for superconductivity from the series is solved with ...

Percolation Effects In Electrical Conductivity Of Carbon Fibre Composites [PDF]

open access: yes, 2011
The effects due to percolation on the bulk electrical conductivity of Carbon Fibre Composites are studied in detail. To simulate the CFCs manufacturing process the fibres are placed randomly in the polymer matrix using Monte Carlo based simulation ...

Effect of solid thermal conductivity and particle-particle contact on effective thermodiffusion coefficient in porous media [PDF]

open access: yes, 2011
Transient mass transfer associated to a thermal gradient through a saturated porous medium is studied experimentally and theoretically to determine the effect of solid thermal conductivity and particle-particle contact on thermodiffusion processes.

Effect of Potassium on A-V Conduction [PDF]

open access: yesCirculation, 1970
"When the potassium is injected slowly, after a time the heart gradually slows to perhaps half its normal rate, the auricle and ventricle being markedly dilated but still contracting synchronously. This is an example of sinus slowing, and is probably due to the direct action of the salt upon what Lewis has termed the `pace-maker' of the heart; it is ...

Effect of Digoxin on A-V Conduction [PDF]

open access: yesBMJ, 1971
The effect of digoxin on A-V conduction in 19 patients with known disease of their conduction tissue was studied while a demand pacing system was in position. Fifteen had transient complete heart block after myocardial infarction and four had chronic intermittent complete heart block. The patients were studied on return to sinus rhythm.

Heat conduction in polymer chains: Effect of substrate on the thermal conductance

open access: yesThe Journal of Chemical Physics, 2022
In standard molecular junctions, a molecular structure is placed between and connected to metal leads. Understanding how mechanical tuning in such molecular junctions can change heat conductance has interesting applications in nanoscale energy transport.

Effective conductivity of 2D disk – ring composite material

open access: yesMathematical Modelling and Analysis, 2013
For 2D bounded composite material geometrically composed by a disk of variable radius r and an outer ring it is determined in an analytic form the x-component of the effective conductivity tensor.
