We investigate the motion of a nano tippe top, which is formed from a C60 fullerene, and which is assumed to be spinning on either a graphene sheet or the interior of a single-walled carbon nanotube. We assume no specific geometric configuration for the top, however for example, the nano tippe top might be formed by joining a fullerene C60 with a small segment of a smaller radius carbon nanotub...
The mechanisms underlying the cytotoxic action of pure fullerene suspension (nano-C60) and water-soluble polyhydroxylated fullerene [C60(OH)n] were investigated. Crystal violet assay for cell viability demonstrated that nano-C60 was at least three orders of magnitude more toxic than C60(OH)n to mouse L929 fibrosarcoma, rat C6 glioma, and U251 human glioma cell lines. Flow cytometry analysis of ...
in this research at the first, xylometazoline hydrochloride drug (xy) and its fullerene connected form (fxy) were optimized. natural bond orbital (nbo) calculations for these compounds were carried out at the b3lyp/6-31g* quantum chemistry level, in the gas phase and the liquid phase. these calculations can be performed at different accuracy levels depending on the aim of the theoretical study....
In this research at the Adenine tautomers and their fullerene derivatives were optimized. NBO calculations and NMR for the tautomers and their Fullerene derivatives were carried out at the B3lyp/6-31G*quantum chemistry level. The core and the valence electrons of atoms were compared. Other cases examined in this study, resonance energy, chemical potential (µ ),...
This study describes a world of new carbon “fullerene” allotropes that may be synthesized by molten carbonate electrolysis using greenhouse CO2 as the reactant. Beyond conventional diamond, graphite and buckyballs, vast array unique nanocarbon structures exist. Until recently, was thought to unreactive. Here, we show can transformed into distinct nano-bamboo, nano-pearl, nano-dragon, solid holl...
we used dbsa and nano-magnetic for the synthesis of amido alkylnaphtols.
Nano carbon materials as nanotube and fullerene have a potential for applications to the advanced industries. For nano carbon materials, it has been recognized that large-scale simulation is a powerful and efficient tool to find and create new functional nano carbon materials. Aiming at conducting the productive simulation for nano-materials, we have developed the large-scale simulation models ...
We have developed a method that enables the efficient insertion of transition-metal atoms and their small clusters into carbon nanotubes. As a model system, Os complexes attached to the exterior of fullerene C60 (exohedral metallofullerenes) were shown to be dragged into the nanotube spontaneously and irreversibly due to strong van der Waals interactions, specific to fullerenes and carbon nanot...
High Energy Materials is a term that is used for explosives, propellants and pyrotechnics. Explosives are used for military applications. 5-Picrylamino-1,2,3,4-tetrazole(PAT) is an explosive substance. In this study the reactions of the 5-Picrylamino-1,2,3,4-tetrazole(PAT) with nanostructures of fullerene and boron nitride nano-cages in different conditions of temperature, with density function...
We are studying the application of the electron cyclotron resonance ion source (ECRIS) for the new materials production on nano-scale. Our main target is the endohedral fullerenes. There are several promising approaches to produce the endohedral fullerenes using an ECRIS. One of them is the ion-ion collision reaction of fullerenes and aliens ions to be encapsulated in the mixture plasma of them...
