Single-walled carbon nanotube ~SWNT! tips have been used to image nanostructures with high resolution. Studies of gold nanocrystal standards showed that SWNT tips provide a significant improvement in lateral resolution with respect to multi-walled nanotube tips and microfabricated Si tips. The nanotube tips were also used to resolve substructure within SWNTs deposited on surfaces. These results...

aim : the aim of this study is to design multi-walled carbon nanotubes (mwcnts) loaded with paclitaxel (ptx) anti-cancer drug and investigate its anti-cancerous efficacy of human gastric cancer. the sidewall surfaces of pristine mwcnts are highly hydrophobic. a major goal in carbon nanotube chemistry has been functionalization for aqueous solubility, and exploiting nano-tubes as macromolecules ...

In the present work a full-dimensional study of the dynamics of a hydrogen molecule confined in a narrow Single-walled Carbon Nanotube (SWCNT) is performed by using the Multi-configurational Time-dependent Hartree approach. New insights on the coupling between the different degrees of freedom of the molecule during the diffusion along the nanotube are found and discussed.

Introduction We have previously reported downsizing ancient twistbased spinning technology for making continuous, densified nanotube yarns from multi-walled carbon nanotube (MWNT) forests [1]. Such nanotube yarns provide unique properties and property combinations. Despite this important progress, the relationship between nanotube yarn properties and component carbon nanotube properties is not ...

An efficient multi-walled carbon nanotube/gold colloidal nanoparticle paste electrode (MWCNTs/ Au Nps PE) was prepared for detection of hydrazine in the presence of pyrogallol red as a mediator in the homogenous solution. The prepared MWCNTs/ Au Nps PE and multi-walled carbon nanotube paste electrode (MWCNTs PE) were characterized by Raman spectroscopy, scanning electron microscopy and cyclic v...

We exploit the remarkable low-friction bearing capabilities of multiwalled carbon nanotubes (MWNTs) to realize nanoelectromechanical switches. Our switches consist of two open-ended MWNT segments separated by a nanometer-scale gap. Switching occurs through electrostatically actuated sliding of the inner nanotube shells to close the gap, producing a conducting ON state. For double-walled nanotub...

X-ray Compton scattering measurements of the electron momentum distribution in water confined in both single-walled and double-walled carbon nanotubes (SWNT and DWNT), as a function of temperature and confinement size are presented here together with earlier measurements of the proton momentum distribution in the same systems using neutron Compton scattering. These studies provide a coherent pi...
