Gas Sensing Properties

Unsubstituted copper phthalocyanine (CuPc) thin films on glass substrate were prepared using spin coating technique. The effects of heat annealing of CuPc films on the NO2 gas sensing properties were studied. The results showed that the films annealed at 150°C have highest sensitivity, highest response rate and lower response time. Sensitivity and response rate were decreased and response time was increased after annealing with temperature 200°C and above. The duration over which the films were annealed changes the gas sensing properties. Highest sensitivity, highest response rate, lower response time and highest recovery rate were observed for 2 hour (150°C) annealed films. Longer annealing time causes the decrease of sensitivity, response rate and recovery rate and increase of response time however improves recovery ratio. The heat treatment limited to the temperature of 150°C for 2 hours duration improves the sensing properties of the films. Hence heat annealed unsubstituted CuPc spin coated films can be used as nitrogen dioxide gas sensor.

Realization probability is a new concept pertaining to perturbation analysis of closed queuing networks. The sensitivities of throughputs in a closed single-class Jackson network can be expressed in terms of realization probabilities. In this paper, based on a discussion of perturbation analysis for networks with state-dependent service rates, we derive some new formulas for sensitivities of throughputs using realization probability.

Effects Of Temperature

Intravascular PO2 electrodes of a commercially available design were tested in vitro to establish their characteristics and to further elucidate on their clinical usability. In addition, four different cathode-anode combinations, utilizing the same geometrical design, were evaluated to establich the best combination. Au-Ag/AgCl exhibited the best characteristics as verified by the evaluation of stabilization time, sensitivity and reproducibility of the response, response time, linearity, drift, effects of temperature, flow, and pH, and the useful life of the sensors. Even though the Au-Ag/AgCl combination exhibited the best characteristics, it fell far below clinically recommended criteria for continuous monitoring of less than 10 Torr/24 h.
