| Abstract | Several precursors such as zinc nitrite, zinc chloride, zinc acetate and zinc sulfate were used to synthesize ZIF-8. These zeolitic imidazolate frameworks synthesized from different zinc precursors under different reaction conditions were characterized by XRD, SEM and FTIR. The synthesis of ZIF-8 was not sensitive to zinc precursor and reaction parameter. Subsequently, we used ZIF-8 to modify the γ-Al$_{2}$O$_{3}$ porous ceramic membrane, expecting improvement of separation performance in the γ-Al$_{2}$O$_{3}$ porous ceramic membrane. The experimental results indicated that the permselectivity of hydrogen/nitrogen was enhanced in the γ-Al$_{2}$O$_{3}$ porous ceramic membrane modified with ZIF-8, although the gas permeance through the modified membrane slightly decreased. In addition, the modified γ-Al$_{2}$O$_{3}$ porous ceramic membrane was used to separate the binary systems containing ethanol-water and acrylic acid-water. The separation factor of ethanol to water is 3.1, while it is 2.6 as for acrylic acid-water. Furthermore, the permeance in the former is about five times than that of the latter. |

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.
