| Abstract | Agarose gels were fabricated by water-in-oil emulsification with the addition of CaCO(3) granules at 8-16 wt%. Thus agarose beads of different superporosities were produced after dissolving the solid porogen. The superporous agarose (SA) and homogeneous agarose gels were double cross-linked and modified with diethylaminoethyl chloride to produce anion exchangers. We have proposed to use a superporous replica (porous titania microspheres) to examine the superporous structure and pore size distribution of the soft gel. The replica was prepared with the agarose gel entrapping CaCO(3) granules by a sol-gel-templating method. It was found that the superpores created by CaCO(3) granules were uniformly distributed and ranged from 0.95 microm to 1.33 microm. The physical properties of the gels were significantly affected by the porogen content. Importantly, by increasing the solid porogen to 12 wt%, the bed permeability and effective porosity increased about 48% and 33%, respectively. Further increase in the porogen to 16 wt% led to a decrease of the mechanical strength. With increasing superpores in the beads, the dynamic adsorption capacity of the packed columns increased obviously at 305-916 cm/h. Besides, the column efficiency changed less with increasing flow velocity up to 1200 cm/h. It was concluded that the use of 12 wt% CaCO(3) granules in agarose solution was beneficial for the fabrication of the SA gel with good mechanical stability and promising performance for protein chromatography. |

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.
