|Abstract||Porous gas diffusion electrodes of two layer and three layer type are prepared by cold compacting and sintering technique. The optimum concentration of acetylene black is 2 wt% and activated charcoal is 10 wt%. The incorporation of silver by different techniques like thermal decomposition of silver salts is presented. The amount of silver varies from 53 mg.cm-2 to 106 mg.cm-2. Electrode area is 30 cmz. The electrodes were polarised as oxygen gas diffusion electrodes in 6.0 M KOH solution at 333K.The electrodes were found to be polarised to -145 mV at 60 mA.cm-2 and to -190 mV at 80 mA.cm9 at 333K. These electrodes have been tested continuously and were found to show the same performance for 500 hrs -7000 hrs. The performance of the same was compared with the electrode containing acetylene black, heat treated and untreated in nitrogen atmosphere at 1073K for 20 hours. Incorporation of platinised acetylene black (carbon) as electrocatalyst for oxygen reduction has also been attempted|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and 9 other languages are available). It is designed 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 being developed to help students to prepare for entrance and competitive examinations, 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 being developed at 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 Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
