Abstract | In this work, a metal-oxide gas sensor array was fabricated for discriminating several gases at room temperature using ultraviolet (UV) illumination. The sensor array consisted of four interdigitated gold microelectrodes, and titanium dioxide (TiO2) nanofibres were electrospun on them. The nanofibres were calcined at 550°C for 1 h. Finally, one of these sensors was coated with a thin layer of gold (Au) using DC sputtering method at a thickness of 2 nm. Similarly, the other two sensors were coated with a thin layer of platinum (Pt) and copper (Cu), respectively, and the last one remained uncoated. The nanofibres were characterised by scanning electron microscope, X-ray diffraction, and UV spectroscopy. The examined analytes were methanol, ethanol, NH3, and acetone, each at seven various concentration levels, including 50, 100, 150, 200, 300, 400, and 500 ppm. Principal component analysis and linear discriminant analysis were used to evaluate the proposed technique. The results demonstrated that the sensor array along with UV illumination could successfully discriminate the analytes at room temperature. |

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.
