The gas sensing potential of the 9CB (4-cyano-4′-nonylbiphenyl) liquid crystal compound at ambient conditions is investigated. solid room temperature incorporated in a hybrid gel formulation ionic liquid/liquid droplets immobilized gelatin matrix. Several liquids are tested order to tackle crystallization and also 9CB-based mixture with different smectogen considered. resulting demonstrates gre...

A major research effort has been devoted over the years for the development of chemical sensors for the detection of chemical and explosive vapors. However, the deployment of such chemical sensors will require the use of multiple sensors (probably tens of sensors) in a sensor package to achieve selective detection. In order to keep the overall detector unit small, miniature sensors with suffici...

Electronic noses utilizes an array of chemical sensors of different specificities which responds to the volatile organic compounds present in the gases. The use of electronic chemical sensors in an array design with coupled signal conditioning and appropriate pattern recognition system is capable of identifying complex odours.Such an artificial gas sensing system is called 'electronic nose'. Th...
