| Abstract | This work presents the results of the characterization of nanostructured Al or Fe matrix composites reinforced with fullerenes. The fullerene used is a mix of 15 wt%C$_{60}$, 5 wt.%C$_{70}$, and 80 wt.% soot that is the product of the primary synthesis of C$_{60}$. The composites were produced by mechanical alloying and sintered by spark plasma sintering (SPS). It was found that in both composites, C$_{60}$ withstands mechanical alloying, and acts as a control agent, reducing the agglomeration of the particles. In both composite systems the as-mechanically alloyed powders as well as the SPS sintered products are nanostructured. During the SPS process the effect of the metal (Al or Fe) matrix with the fullerene is different for each composite. For instance, Al reacts with all the carbon in the fullerene mix and forms Al$_{4}$C$_{3}$; on the contrary, in the Fe-fullerene composite, Fe sponsors the synthesis of C$_{60}$ during the SPS process. The synthesis of the C$_{60}$ is presumably assisted by the catalytic nature of Fe and the electric field generated during the SPS sintering process. |

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.
