| Abstract | Poly(2-hydroxyethylmethacrylate) (PHEMA) is one of the most well known synthetic hydrogels. In this study, PHEMA gel containing a charge transfer dye was synthesized using a copolymerization method. This polymer gel swelled appropriately in water with a swelling ratio (Q) of approximately 1.0, and swelled significantly in aprotic polar solvents, such as DMF and DMSO, with Q values of >8.0, whereas it never swelled in nonpolar solvents. The fluorescence (FL) emission band of the hydrogel polymer showed a red shift exclusively in water, whereas it showed a blue shift in the other solvents tested. The emission band also shifted to shorter wavelengths with increasing proton activity (with decrease in pH) or iron cation concentration, and the FL intensity increased gradually. The FL intensity also decreased significantly with increasing absolute humidity.A charge transfer dye-based PHEMA gel was synthesized using a copolymerization method.

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.
