| Abstract | In ozone production using streamer discharges by pulsed power, the concentration of ozone is not high although ozone is produced with high efficiency. To improve ozone concentration, we studied the effects of electrode separation in a coaxial reactor using nanosecond pulsed power. We found that ozone concentration and yield increase with decreasing inside diameter of the outer electrode in the reactor. This occurs because dense plasma forms in a small-diameter reactor that has a small electrode separation. As the repetition rate of applied pulses was increased, the ozone yield remained nearly constant, while the ozone concentration increased proportionally. However, in a reactor having a small diameter of 17 mm, the tendency for the concentration to saturate and reductions in the ozone concentration were found to depend on pulse repetition rate. In such a small-diameter reactor, spark discharges occurred owing to the reduced separation of electrodes; these discharges cause the temperature of electrodes and gases to increase. Consequently, ozone molecules thermally dissociated and ozone concentration decreased. The occurrence of spark discharges was affected by not only the small separation of electrodes but also other factors. Potential of a small-diameter coaxial reactor for ozone production were presented and a control of occurrence of spark discharges was paramount. |

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.
