Reinforcing Multi-Wall Carbon Nanotubes by Electron Beam Irradiation

To prepare the samples for Transmission Electron Microscopy (TEM) imaging and Atomic Force Microscopy (AFM) measurements, as-grown carbon nanotubes were dispersed in isopropanol and sonicated using HD2200 homogenizer with a power of 20W for 5 minutes. To characterize the nanotubes by HRTEM, a droplet of the suspension was put on a Cu TEM grid with a lacey C film. Alternatively, we deposited a d...

Transmission electron microscopy at 20 kV for imaging and spectroscopy.

The electron optical performance of a transmission electron microscope (TEM) is characterized for direct spatial imaging and spectroscopy using electrons with energies as low as 20 keV. The highly stable instrument is equipped with an electrostatic monochromator and a C(S)-corrector. At 20 kV it shows high image contrast even for single-layer graphene with a lattice transfer of 213 pm (tilted i...

Carbon Nanotubes as Diffraction Microscopy Mounts

Consider the possibility of using carbon nanotubes as a sample mount for individual biomolecules in a diffraction microscopy apparatus. You should consider this question in the context of developing a generalpurpose method to replace the huge efforts currently employed in structural biology. For example, can you think of a way to make arbitrary proteins stick to a nanotube (at some low linear d...

Electrochemical Sensor for Determination of Fenitrothion at Multi-wall Carbon Nanotubes Modified Glassy Carbon Electrode

A sensor, based on multi-wall carbon nanotubes modified glassy carbon electrode (MWCNT/GCE), was developed for determination of fenitrothion. Determining the surface area of MWCNT/GCE showed that this surface is three times more active than that of a glassy carbon electrode. The experimental parameters, such as the amount of MWCNTs, pH of the fenitrothion solution, preconcentration potential an...

Low pressure adsorption of CO2 on multi-wall carbon nanotubes

Volumetric techniques were employed to study the adsorption of CO2 on a purified multi-wall carbon nanotubes (MWNT’s) sample, as a mesoporous material, at isothermal conditions of 288, 293 and 298 K and pressures ranging from 30 to 150 kPa. Langmuir, Freundlich and Sips equations were used to represent the isotherms. Also the parameters of these fitted isotherm models have been determined. The ...
