Multi-walled carbon nanotubes (MWCNTs) are elongated cylindrical nanoobjects made of sp2 carbon. Their diameter is 3–30 nm and they can grow several cm long, thus their aspect ratio can vary between 10 and ten million. They can be distinguished from single-walled carbon nanotubes on the basis of their multi-walled Russian-doll structure and rigidity ...

Magnetic Properties of Multi-Walled Carbon Nanotubes
Journal of Nanoscience and Nanotechnology, 2009The magnetic properties of multiwall carbon nanotubes (MWCNTs) grown by microwave plasma enhanced chemical vapor deposition (MPECVD) were studied by electron paramagnetic resonance and magnetization measurements. The ferromagnetic characters of virgin grown MWCNTs are mainly attributed to the catalyst nanoparticles embedded on the tips.

CESR in multi walled carbon nanotubes
Physica E: Low-dimensional Systems and Nanostructures, 2003Abstract We have clarified carrier spin relaxation process in multi walled carbon nanotubes (MWCNT) fabricated by DC arc discharge and studied the fundamental transport mechanism in MWCNT by means of electron spin resonance (ESR) in order to discuss on the transport properties in the MWCNT.

Cutting of multi walled carbon nanotubes
Applied Surface Science, 2006Abstract Multi walled carbon nanotubes (MCNT) synthesized by CVD method have been successfully cut into different lengths by controlling H2SO4/HNO3 (5:3) oxidation time. During the cutting process H2SO4 and HNO3 were added independently and the oxidation processes were carried out at a lower temperature to void excess weight loss and damage to MCNT ...

Functionalization of Multi-Walled Carbon Nanotubes
Materials Science Forum, 2007In order to alter the physical/chemical characteristics of multi-walled carbon nanotubes (MWNTs) we modified them by different organic reactions (Diels-Alder and Sand-Meyer reaction, oxidation) and their d properties were characterized by thermogravimetry/mass spectrometry, photoelectron spealterectroscopy, and nuclear magnetic resonance spectroscopy ...

Silylation of multi-walled carbon nanotubes
Chemical Physics Letters, 2003Functionalisation of carbon nanotubes is expected to improve their utility in a range of applications. This paper describes a method of silylating multi-walled nanotubes that have first been acid treated in order to introduce polar surface groups. A range of reagents were tested and N-(tert-butyldimethylsilyl)-N-methyltrifluoroacetamide (MTBSTFA) or 1-(

Lipase immobilized on magnetic multi-walled carbon nanotubes
Bioresource Technology, 2012Magnetic iron oxide nanoparticles were loaded onto the surfaces of multiwalled carbon nanotubes (MWNTs) by the impregnation method. The obtained magnetic nanotubes were characterized with high-resolution transmission electron microscopy (HRTEM), X-ray photoelectron spectroscopy (XPS), and X-ray diffraction (XRD).

Ag-catalysed cutting of multi-walled carbon nanotubes
Nanotechnology, 2016In this work, the cutting of carbon nanotubes is investigated using silver nanoparticles deposited on arc discharge multi-walled carbon nanotubes. The composite is subsequently heated in air to fabricate shortened multi-walled nanotubes. Complementary transmission electron microscopy and spectroscopy techniques shed light on the cutting mechanism.
