| Abstract | A simple method for the preparation of carbon nanotubes (CNTs) from bitumen waste and their derivatisation with polyacrylamide was achieved. Synthesised CNTs were functionalised in the presence of dilute nitric acid followed by derivatisation with polyacrylamide using the mixture of potassium persulphate-ferrous ammonium sulphate as a redox initiator and N,N′-methylene-bis-acrylamide as a crosslinking agent. The functionalisation and derivatisation of the CNTs were confirmed through Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and X-ray diffraction techniques. The effect of derivatisation on the thermal properties of the CNTs was studied by thermogravimetric analysis, differential thermogravimetric analysis and differential thermal analysis. The crosslinked derivatised product, CNT-cl-poly(AAm), was thermally more stable than the functionalised CNTs. The water-absorption capacity of the derivatised CNTs was investigated in deionised water as a function of time, temperature and pH of the swelling medium. CNT-cl-poly(AAm) was found to be an efficient water-absorption device with the maximum absorption capacity of 476 %. |

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.
