Background: CNT’s are nanomaterials that are one-dimensional structure, which are considered to be of the 2nd generation allotrope of carbon. They usually constitute pure carbon and carbon atoms are present in a repetitive manner in a hexagonal pattern an... see more

El carbono es uno de los elementos más abundantes de la naturaleza. Su particular estructura hace que pueda tener hasta cinco tipos distintos de alótropos. Durante los últimos años se han producido grandes avances en el estudio de estos materiales de carb... see more

In this work, the synthesis of carbon nanotubes was carried out on the sand surface with hydrophobic properties by chemical vapor deposition (CVD). The effective temperature for the synthesis of carbon nanotubes is 800 °C. Propane-butane gas mixture was u... see more

Sol-gel method has been used to coat multiwalled carbon nanotubes (MWCNTs) with zirconia at room temperature and the coated tubes were sintered at high temperature. The samples were characterised by Raman spectroscopy, x-ray diffraction, environmental sca... see more

The opportunity of creating and tailoring unprecedented and beautifully symmetric 3-D structures haspropelled the science of carbon nanotubes to become one of the highly promising areas in the field ofnanotechnology. The unique properties of carbon nanotu... see more

An exceptionally high yield of carbon nanotubes (CNTs) has been achieved by chemical vapour deposition (CVD) of camphor over zeolite support. A simple 30 min CVD of 12 g camphor over Fe-Co-impregnated zeolite at 650 °C in an academic laboratory setup, yie... see more

Carbon nanotubes have attracted the fancy of many scientists world wide. The small dimensions,strength, and the remarkable physical properties of these structures make them a unique material with a whole range of promising applications. In this review, th... see more

The study analyzes the published literature data on key properties of one of the most important nanomaterials,carbon nanotubes. This material has a wide range of applications for biological and medical use. Among them there are visualization of molecular,... see more

L’objectif de ce travail est l’étude thermodynamique et structurale du nanocomposite Al+0,25% nanotubes multiparois de carbone. Pour la réalisation de cet article, nous avons utilisé plusieurs techniques expérimentales: la calorimétrie, la diffraction des... see more
