| Abstract | The Cu@BaTiO3 powders were synthesised by a simple low-cost hydrothermal method for the very first time. The effects of copper (Cu) contents on the formation of core(Cu)@shell(BaTiO3) powders have been investigated by X-ray powder diffraction, scanning electron microscopy and energy dispersive spectrometer. Notably, the existence of Cu@BaTiO3 powders can only be obtained when Cu content happened to be 20%. A novel modification method, gaseous rare-earth penetration, has been adopted to reduce the resistivity and prepare Cu@BaTiO3 conductive powders. The results indicated that rare-earth penetration turned out an effective way to lower the resistivity of Cu@BaTiO3 powders significantly. Surprisingly, the core–shell structure of Cu@BaTiO3 powders has not perished after rare-earth penetration. Furthermore, the resistivity of Cu@BaTiO3 conductive powders turned out to be 8.30 × 10−4 Ω m, which can be a promising candidate for novel and environmental-friendly conductive powders. |

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.
