| Abstract | Metallic oxides aerosols are prepared by decomposition of anhydrous chlorides in the diffusion flame of a hydrogen–oxygen reactor. The flow rate of the chloride vapour, the temperature of the flame and the residence time of the reagent in the flame determine the shape (spherical or polyhedral), the dimensions (in the range from 60 Å to 2000 Å) and in some cases the crystalline structure of the particles, which in all cases are non-porous.These highly divided oxides exhibit unusual photocatalytic properties which are not encountered with aerosols in the micron range or with porous particles prepared in a conventional way. Titanium dioxide, in particular, enables the catalytic photo-oxidation (in the u.-v. range) at room temperature of organic and inorganic compounds. Paraffins and olefins are oxidized partially and/or totally whereas ammonia yields N2O and N2, carbon monoxide yields carbon dioxide and hydrogen sulphide yields sulphur dioxide and sulphur. |

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.
