| Abstract | Blended nanofiber webs of poly(L-lactic acid) (PLLA)/poly(L-lysine) (PLys) with a PLys content of up to 3 % were prepared using an electro-spinning process with trifluoroacetic acid as the spinning solvent, and employed as a substrate for silicification. Silica formation on the surface of the PLLA/PLys nanofibers was carried out by immersing the nanofiber webs in silicic acid solutions at various concentrations for different times. The effects of the silicification conditions and PLys content on silicification were examined by scanning electron microscopy, FT-IR, energy dispersive spectroscopy, and the increase in weight of the substrates. Although the amount of silica formed on the PLLA nanofibers increased with increasing silicification time and silicic acid concentration, the uniformity of the coated layer was not controlled. However, the incorporation of small amounts of PLys in the PLLA nanofibers increased the amount and uniformity of the silica formed on the nanofibers. |

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.
