Applied Physics and Mathematics Annotation << Back Methane nanosensors for fire-explosion safety of objects of mining, transportation and usage of natural gas Yu.А. Sorokin Development results of methane nanosensors are considered in the article. These devices are systematized according to construction features of their sensitive elements. Thus three nanosensor groups are defined. Group 1 is devices sensitive elements of which have a covering from metal oxide. Group 2 is nanosensors with the sensitive elements containing a covering from metal oxide and an external layer of other material. Group 3 is devices sensitive elements of which have a covering from composite. Information on the basic technical characteristics of the listed nanosensor groups (composition, morphology and thickness of a covering of sensitive element, kind of measuring transducer, measurement range, temperature of sensitive element, response time, recovery time) are submitted. The applicability of the developed devices for fire-explosion safety of objects of mining, transportation and usage of natural gas is analyzed.
