Iranian Scientists Design Nano Device to Detect Cyanogen Toxic Gas

Abstract:
Iranian researchers studied the effect of a type of nanosheet on the adsorption of cyanogen toxic gas.

Story:
Results of the research have applications in designing gas sensors to detect the toxic gas in the environment.

Cyanogen is a colorless and odorless gas that smells bitter almond, which is used in wars. This toxic gas causes digestive problems, including nausea and vomiting, convulsion, coma, pupil dilatation and the slow reaction of pupil to light.

This research studied the adsorption of the cyanogen from the environment by using a nanosheet made of boron nitride. The calculations have been carried out at the theoretical level.

Based on the results, boron nitride nanosheet adsorbent is very good for the adsorption of cyanogen, and it can be used in designing gas-sensitive sensors to detect and separate the toxic gas from the environment. Studies showed that when the sheets are doped with silicon, the amount of cyanogen sorption significantly increases. Therefore, boron nitride nanosheets doped with silicon can be used to modify the performance of the sensors.

Various parameters effective on the adsorption of the nanosheets, including the type of atoms and size of sheets were studied in this modeling to obtain the optimum result.

Results of the research have been published in Indian Journal of Fundamental and Applied Life Sciences, vol. 5, issue S1, 2015, pp. 5074-5080.
