| Abstract | The catalysis of cyclopentane–deuterium exchange by nickel–copper alloy films persists to low (4 atom %) nickel content. Activation energies where measurable and product distribution patterns are constant for nickel contents greater than ca. 24 atom % nickel, but below this value there is a marked increase in over-all activation energy and an even-numbered distribution pattern (maxima for tetra- and hexa-deuterio-products) develops. The latter feature is ascribed to doubly bonded intermediate described as ααββ- and ααββγγ-adsorbed. These are the species believed to be responsible for the severe self-poisoning found on pure nickel. The strength of their adsorption decreases with the increasing fraction of copper, causing initially a decrease in the extent of self-poisoning and ultimately the appearance of the even-numbered deuteriocyclopentane exchange products. These features are discussed in terms of compositional and texture changes. |

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.
