|Abstract||A new strategy involving the introduction of a cationic surfactant, cetyltrimethylammonium bromide (CTAB), for the modification of electrodes with cobalt hexacyanoferrate (CoHCF) film has been found to be beneficial. The surfactant has been found to influence the electrochemical properties of the CoHCF-modified electrode by way of enhancement of voltammetric currents and reversibility of redox reactions. CoHCF surface films deposited by a potential cycling procedure in the presence and absence of CTAB are compared for K+ transport characteristics, using cyclic voltammetry (CV). CV parameters in 0.1 M KCl + 0.1 M HCl for electrodes modified both in the presence and in the absence of CTAB and diffusion coefficient values obtained from double potential step chronocoulometry at different pulse widths are presented and discussed. A comparative study is made for the transport behavior of K+, Na+, Li+, and NH4 + ions through CoHCF films, prepared both in the presence and in the absence of CTAB.|

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.
