| Abstract | Microfluidics configuration may facilitate greater success for photocatalytic water treatment. In this paper, we designed a planar microfluidic reactor which can overcome the limitations of mass transfer and photon transfer in the previous photocatalytic reactors and improve the photoreaction efficiency by 2 orders of magnitude. The microreactor consisted of two TiO-coated glass slides and a microstructured UV-cured NOA81 layer, forming a planar chamber (5 cm × 1.8 cm × 100 µm). In our studies, methylene blue (MB) was used as the model chemical. 3 ml MB solution $(3×10^{−5}$ M) was degraded by more than 60% within 15 min using the microfluidic reactor, and the reaction rate constant was found to be 100 times higher than that by using the bulk reactor. The photodegradation performance of the microreactor was also optimized by adjusting the TiO film thickness and flow rate and achieved a reaction rate of 8% $s^{−1}$ under solar irradiation. |

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.
