Effect of van der Waals forces on thermal conductance at the interface of a single-wall carbon nanotube array and silicon

AIP Advances, 2014
Molecular dynamics simulations are performed to evaluate the effect of van der Waals forces among single-wall carbon nanotubes (SWNTs) on the interfacial thermal conductance between a SWNT array and silicon substrate.

Exploring Forces between Individual Colloidal Particles with the Atomic Force Microscope

CHIMIA, 2012
Forces between individual colloidal particles can be measured with the atomic force microscope (AFM), and this technique permits the study of interactions between surfaces across aqueous solutions in great detail.

Dynamical importance of van der Waals saddle and excited potential surface in C(1D)+D2 complex-forming reaction

Nature Communications, 2017
It is commonly held that van der Waals wells are inevitable in chemical reactions. Here, the authors show that weak van der Waals forces in the entrance channel of a prototypical complex-forming reaction cause a van der Waals saddle instead, with ...

Van der Waals interactions and the limits of isolated atom models at interfaces

Nature Communications, 2016
Van der Waals forces are individually weak, but on scale can drive many nano- and macroscopic processes. Here, Kawai et al. directly measure the van der Waals interactions between noble gas atom pairs and show how this changes with atom size and surface ...

SAPT: ligação de hidrogênio ou interação de van der Waals?

Química Nova, 2012
It is through the application of an electronic partition approach called Symmetry-Adapted Perturbation Theory (SAPT) that the nature of hydrogen bonds and van der Waals interactions can be unveiled according to the contribution of electrostatic, charge ...

Effects of the van der Waals Force on the Dynamics Performance for a Micro Resonant Pressure Sensor

Shock and Vibration, 2016
The micro resonant pressure sensor outputs the frequency signals where the distortion does not take place in a long distance transmission. As the dimensions of the sensor decrease, the effects of the van der Waals forces should be considered.

Refined 2D and Exact 3D Shell Models for the Free Vibration Analysis of Single- and Double-Walled Carbon Nanotubes

Technologies, 2015
The present paper talks about the free vibration analysis of simply supported Single- and Double-Walled Carbon Nanotubes (SWCNTs and DWCNTs). Refined 2D Generalized Differential Quadrature (GDQ) shell methods and an exact 3D shell model are compared.
