Effective Conductivity of Carbon-Nanotube-Filled Systems by Interfacial Conductivity to Optimize Breast Cancer Cell Sensors [PDF]

open access: yesNanomaterials, 2022
Interfacial conductivity and “Lc”, i.e., the least carbon-nanotube (CNT) length required for the operative transfer of CNT conductivity to the insulated medium, were used to establish the most effective CNT concentration and portion of CNTs needed for a ...

Simulating of effective conductivity for graphene–polymer nanocomposites [PDF]

open access: yesScientific Reports, 2023
The efficient conductivity of graphene-polymer systems is expressed supposing graphene, tunneling and interphase components. The volume shares and inherent resistances of the mentioned components are used to define the efficient conductivity.

Estimating the effective conductivity for ellipse-inclusion model with Kapitza thermal resistance

open access: yesEPJ Applied Metamaterials, 2021
The ellipse assemblage model with imperfect interface has quite complex microstructure, that can be considered an extension of the circle assemblage model with imperfect interfaces.

The Effects of Propranolol on Cardiac Conduction [PDF]

open access: yesCirculation, 1969
The effects of propranolol, 0.1 mg/kg given intravenously, on atrioventricular (A-V) conduction and intraventricular (IV) conduction were studied in eight patients. Atrial pacing was used to control the heart rate. His bundle electrograms were recorded, and the interval from the pacing impulse to the His bundle electrogram (P-H interval) was used as a ...

Cooperative Effects in Molecular Conduction [PDF]

open access: yesJournal of Computational and Theoretical Nanoscience, 2008
Current experimental and theoretical studies on the effect of intermolecular interactions on molecular conduction appear to be in conflict with each other. In particular, some experimental results, e.g., the observation of 2-dimensional free-particle character for interface bound electrons indicate strong intermolecular interactions while other ...

Size dependent of the effective conductivity of composite with imperfect interfaces

open access: yesVietnam Journal of Mechanics, 2020
Based on the circle assemblage model, the effective properties of the inclusion with imperfect interface are derived. The equivalent inclusion is incorporated in the Fourier Transform algorithm to determine the effective conductivity of the composite ...

A further discussion on the effective thermal conductivity of metal foam: An improved model [PDF]

open access: yes, 2015
In this study, we explain the causes and effects of the geometrical impossible result encountered in the widely adopted tetrakaidecahedron model (Boomsma and Poulikakos, 2001; Dai et al., 2010) for the effective thermal conductivities (ETCs) of metal ...
