A developed equation for electrical conductivity of polymer carbon nanotubes (CNT) nanocomposites based on Halpin-Tsai model

open access: yesResults in Physics, 2019
This paper expresses a simple equation for conductivity of polymer carbon nanotubes (CNT) nanocomposites (PCNT) based on Halpin-Tsai model supposing the volume fraction of networked CNT, CNT conductivity, CNT size and tunneling dimensions between ...

Intercellular Communication in the Brain through Tunneling Nanotubes. [PDF]

open access: yesCancers (Basel), 2022
Intercellular communication is essential for tissue homeostasis and function. Understanding how cells interact with each other is paramount, as crosstalk between cells is often dysregulated in diseases and can contribute to their progression. Cells communicate with each other through several modalities, including paracrine secretion and specialized ...

Nanospintronics with carbon nanotubes [PDF]

open access: yes, 2006
One of the actual challenges of spintronics is the realization of a spin-transistor allowing to control spin transport through an electrostatic gate. In this review, we report on different experiments which demonstrate a gate control of spin transport in

Electronic spectra of commensurate and incommensurate DWNTs in parallel magnectic field [PDF]

open access: yes, 2009
We study the electronic spectra of commensurate and incommensurate double-wall carbon nanotubes (DWNTs) of finite length. The coupling between nanotube shells is taken into account as an inter-shell electron tunneling. Selection rules for the inter-shell

Percolation onset and electrical conductivity for a multiphase system containing carbon nanotubes and nanoclay

open access: yesJournal of Materials Research and Technology, 2021
The modeling methods estimating the conductivity of multiphase systems are limited. In this article, two simple equations are developed for percolation onset and electrical conductivity of multiphase polymer systems containing carbon nanotubes (CNTs) and

Nonequilibrium Singlet-Triplet Kondo Effect in Carbon Nanotubes [PDF]

open access: yes, 2006
The Kondo-effect is a many-body phenomenon arising due to conduction electrons scattering off a localized spin. Coherent spin-flip scattering off such a quantum impurity correlates the conduction electrons and at low temperature this leads to a zero-bias

Tunneling Nanotubes: Intimate Communication between Myeloid Cells

open access: yesFrontiers in Immunology, 2018
Tunneling nanotubes (TNT) are dynamic connections between cells, which represent a novel route for cell-to-cell communication. A growing body of evidence points TNT towards a role for intercellular exchanges of signals, molecules, organelles, and ...

Mapping of functionalized regions on carbon nanotubes by scanning tunneling microscopy

open access: yes, 2010
Scanning tunneling microscopy (STM) gives us the opportunity to map the surface of functionalized carbon nanotubes in an energy resolved manner and with atomic precision. But this potential is largely untapped, mainly due to sample stability issues which

Perspectives of cellular communication through tunneling nanotubes in cancer cells and the connection to radiation effects

open access: yesRadiation Oncology, 2019
Direct cell-to-cell communication is crucial for the survival of cells in stressful situations such as during or after radiation exposure. This communication can lead to non-targeted effects, where non-treated or non-infected cells show effects induced ...
