| Abstract | The possibility is shown to obtain a nanodispersed powder with the spherical shape particle and with the equal components distribution in a hypervelocity electrical discharge plasma jet generated by a coaxial magnetoplasma accelerator (CMPA). The developed method allows to obtain: nanodispersed (∼ 50 nm), polymorphic crystalline TiO2 phases with the admixture of cubic TiN by the titanium plasma efflux in the air atmosphere; nanodispersed (10 ÷ 40 nm) TiO2 (rutile) crystalline phases with the TiC admixture by the titanium plasma efflux in the CO2 atmosphere; nanodispersed (30÷70 nm) cubic TiN by the titanium plasma efflux in the nitrogen atmosphere; nanodispersed composite powders by using electrodes of the CMPA made of several different metals, mixture of different gases and additional reagents introduction in the high-current discharge plasma jet. The process, including such stages as the electroerosive obtaining of the initial material, the dynamic synthesis, the nanodispersed particles formation, is fully realized in the short term $(10^{−4}$ ÷ $10^{−3}$ sec.) cycle of the accelerator work. The basic initial material is generated by the electric erosion from the CMPA acceleration channel surface. |

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.
