| Abstract | Aligned multi-wall carbon nanotubes (CNTs) were synthesized by a catalytic cracking chemical vapor deposition (CC-CVD) method. The effects of hydrogen flow rates and hydrocarbon amounts were studied to selectively synthesize carbon nanomaterials at high yield, high purity, and high quantity. Iron nanoparticles that were produced from the thermal decomposition of iron oxide on the surface of aluminum oxide powder were used as a catalyst for the synthesis of the carbon structures. The effects of different hydrogen flow rates (10–700 ml/min) and the amount of ethylene gas (50–700 ml/min) on the morphology, quality and quantity of the product were investigated. The thermal oxidation kinetics of CNTs was investigated by dynamic thermogravimetry, in an air atmosphere, over the temperature range 25–800 °C and at constant nominal heating rate 10 °C/min. The corresponding activation energies, frequency factors, and reaction orders were determined. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
