Abstract | With the aim of preparing a low-cost filler material to enhance the bondability of a sinter-bonding paste, submicrometre Cu particles with little agglomeration were successfully synthesised by a simple solvothermal recipe using CuO as a precursor and triethanolamine as a solvent. The required synthesis time and the average size (216–821 nm) of the synthesised Cu particles decreased proportionally with the increasing synthesis temperature. The required synthesis times were found to be 30 and 60 min and the particle sizes of 410 and 821 nm were achieved at synthesis temperatures of 200 and 180°C, respectively. The CuO particles were transformed into Cu2O nanoparticles by accepting the hydrogen ions and electrons released during the conversion of the triethanolamine to the aldehyde by the oxidation of its three hydroxyl groups. Submicrometre pure Cu particles could be subsequently formed from aggregates of the Cu2O nanoparticles by removing O ions from Cu2O during the continuous conversion of the aldehyde to nitrilotriacetic acid. |

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.
