| Abstract | ZrO2 fibres have been used in aspects of aeronautics and astronautics because of their properties such as high strength, good toughness and thermal shock resistance. In this reported work, polyvinylpyrrolidone (PVP)/Y(NO3)3·6H2O/ZrOCl2·8H2O (PVP-precursor) nanofibres were prepared by the sol–gel method and an electro-spinning technique. Then, the ZrO2 fibres by Y-doping were obtained by calcination of the above precursor fibres at 550°C for 0.5 h. These fibres were characterised by X-ray diffraction, scanning electron microscopy, energy-dispersive X-ray spectroscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry and thermogravimetry to study the physical and chemical properties. The formation mechanism of ZrO2 fibres is also illustrated. The results show that: (i) the diameter of the nanofibres is in the range of 500–3000 nm; (ii) PVP-precursor fibres should reach the level of obvious dehydration, oxidation decomposition and phase transition to synthesise ZrO2 nanofibres; (iii) through thermal poly-condensation reaction, PVP turns into a network structure of graphitised carbon. |

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.
