| Abstract | The purpose of this study is to develop a novel semi-active micro-mixer. The developed mixer has neither obstacles in microchannels or external electrical power sources outside the microchannel. However, an oil-base ferro-nanofluid is employed to segment two aqueous solutions into droplets when two aqueous solutions interact with the oil-based ferro-nanofluid at a dragonfly shape junction. The mixing between two aqueous solutions in the droplet can be significantly enhanced when the ferro-nanofluid carrying the droplets flow through a permanent magnet outside the microchannel. It is due to the reason that boundaries between the droplets and the oil-based ferro-nanofluid are distorted when the carrier ferro-nanofluid moves into and out of the magnetic field exerted by the permanent magnet. Since no external electrical power is required in the developed micromixer for enhancing the mixing between two aqueous solutions. This type of micro-mixer is called a “Semi-Active Micromixer”. |

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.
