by employing the theoretical method based on tight-binding, we study electronic band structure of single-wall carbon nanotube (cnt) superlattices, which the system is the made of the junction between the zigzag and armchair carbon nanotubes. exactly at the place of connection, it is appeared the pentagon–heptagon pairs as topological defect in carbon hexagonal network. the calculations are base...

The present study concerns experimental and fin ite element analysis of carbon epoxy and carbon epoxy carbon nanotube composites to estimate interlaminar shear strength. Mechanical properties such as elastic ratios, thickness are varied for double notched specimen and the corresponding deflections and interlaminar shear strengths are estimated by ANSYS. From simple ru le of mixtures, equivalent...

Friction properties of carbon nanotubes have been widely studied and reported, however, the friction properties of carbon nanotubes related on state of itself. It is showing superlubricity under nanoscale, but indicates high shear adhesion as aligned carbon nanotube film. However, friction properties under high load (which is commonly in industry) of carbon nanotube films are seldom reported. I...

Carbon nanotube-In2O3 nanocomposites were synthesized by sol-gel method with the help of ultrasonic radiation. The samples were characterized by X-ray diffractometer, transmission electron microscopy and energy dispersive spectrometer. The UV absorbing properties were detected by the UV spectrophotometer. Photo degradation of methylene blue in aqueous solution was investigated by using CNT/In2O...

Carbonaceous mesophases are liquid crystalline precursor materials that can be spun into high performance carbon fibers using the conventional melt spinning process. Carbon fiber property optimization requires a better understanding of the principles that control the structure development during the fiber formation processes and the rheological processing properties. This work presents the elas...

in this work the conduction of ion-water solution through two discrete bundles of armchair carbon and silicon carbide nanotubes, as useful membranes for water desalination, is studied. in order that studies on different types of nanotubes be comparable, the chiral vectors of c and si-c nanotubes are selected as (7,7) and (5,5), respectively, so that    a similar volume of fluid is investigated ...

Imogolite nanotubes (INTs) display a range of useful properties and provide an ideal material system to study the assembly nanomaterials into macroscopic fibers. A method wet spinning pure, binder-free imogolite fibers has been developed using double-walled germanium nanotubes. The nanotube aspect ratio can be controlled during initial synthesis is critical process. Fibers made from short (<100...

Bovine serum albumin is commonly used in many biochemical applications due to its stability, lack of interference within biochemical reactions and low production cost. Here, we model the interaction of bovine serum albumin inside a carbon nanotube. The carbon nanotube is chosen as an example to demonstrate its potential use in targeted drug and protein delivery and as an enzyme immobilizing mat...
