Chemical sensors are integral to the automation of myriad industrial processes and everyday monitoring of such activities as public safety, engine performance, medical therapeutics, and many more. This 4 volume reference work covering simulation and modeling will serve as the perfect complement to Momentum Press’s 6 volume reference works "Chemical Sensors: Fundamentals of Sensing Materials" and "Chemical Sensors: Comprehensive Sensor Technologies", which present detailed information related to materials, technologies, construction and application of various devices for chemical sensing. This 4 volume comprehensive reference work analyzes approaches used for computer simulation and modeling in various fields of chemical sensing and discusses various phenomena important for chemical sensing such as bulk and surface diffusion, adsorption, surface reactions, sintering, conductivity, mass transport, interphase interactions, etc. In this work it will be shown that theoretical modeling and simulation of the processes, being a basic for chemical sensors operation, could provide considerable progress in choosing both optimal materials and optimal configurations of sensing elements for using in chemical sensors. Each simulation and modeling volume in the present series reviews modeling principles and approaches peculiar to specific groups of materials and devices applied for chemical sensing. Volume 3: Solid State Devices covers phenomenological and molecular modelling of processes which control sensing characteristics and parameters of various solid state chemical sensors including surface acoustic wave, MIS, microcantilever, thermoelectric-based devices and sensor array aimed for electronic nose design. Modeling of nanomaterials and nanosystems promising for solid state chemical sensors design is analyzed as well.
