| Abstract | Three carbon aerogels (AGC) were prepared using the sol–gel method from the polymerization of mixtures of resorcinol–catechol (RC), resorcinol-m-cresol, and resorcinol–phloroglucinol (RP). Cobalt acetate was used as polymerization catalyst. The porous texture and the morphology of carbon aerogels were characterized by nitrogen adsorption at 77 K, carbon dioxide at 273 K and scanning electron microscopy. Their structure and chemical surface were analyzed by means of X-ray diffraction and X-ray photoelectron spectroscopy. It was found that the addition of a second phenol influences the porosity of the material. The carbon aerogel prepared with m-cresol as a monomer presented constrictions at the entrance of the micropores and lower pore volume compared to that of RC and RP. This fact is possibly due to the presence of the methyl group. Moreover, this monomer favors the formation of carbon fibers. |

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.
