| Abstract | Activated carbon from sugarcane residues, bagasse and straw was obtained with phosphoric acid activation. All samples were characterized by N$_{2}$ adsorption–desorption isotherm, scanning electron microscopy, coupled with energy dispersive microscopy, X-ray photoelectron spectroscopy and thermal analysis. The advantages of using a ball or hammer milling process were investigated, together with the effect of the impregnation ratio and its influence on the final activated carbon porosity. The results show that all samples exhibit a high surface area and well developed porosity, but those which were ball-milled have a greater gas adsorbed amount, especially those which had straw (1415 m$^{2}$/g) as precursor material. Furthermore, the results suggest that the process may have an optimum impregnation ratio, which should be around 2 or 3, irrespectively of the lignocellulosic source material. The mechanochemical process seems to be more relevant than the percentage of cellulose in the raw material. According with spectroscopy results, the homogeneous distribution of phosphorus throughout the sample was verified, even after repeated washing steps. Surface phosphate linkages like C–O–PO$_{3}$ and C–PO$_{3}$ were also detected. |

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.
