| Abstract | This paper describes in-situ chemical vapor deposition (CVD) method to deposit alumina catalyst bed selectively on the suspended membrane of a microreactor. The microreactor with suspended membrane structure can realize good thermal isolation of the reaction area on the membrane, because heat conduction through the thin suspended membrane is quite small. However, it is difficult to form catalyst selectively on the suspended membrane. The solution can be given by the in-situ CVD method, by which alumina is deposited from alumina precursor selectively on the suspended membrane heated by integrated micro-heaters. We fabricated the suspended-membrane microreactors, and set up an in-situ CVD system using aluminum tri-isopropoxide (Al[(CH/sub 3/)/sub 2/CHO]/sub 3/) as the precursor. Preliminary deposition tests were preformed. The deposits were observed using a scanning electron microscope (SEM), and the composition of the deposits was analyzed by energy dispersive spectroscopy (EDX). |

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.
