Electronics environmental chemical engineering

Surface tension is an important property in the study of physics and chemistry at free surfaces as it affects the transfer rates of vapor absorption at the vapor-liquid interface. Such data are of importance to scientists, engineers, and practitioners in many fields such as chemical process and reactor engineering, flow and transport in porous media, materials selection and engineering, biomedical and biochemical engineering, electronic and electrical engineering, etc. The surface of a liquid is not only interesting for the fundamental aspects but also for its relevance in environmental problems, biological phenomena, and industrial applications. 

I believe that these books will also be useful to university students, postdocs, and professors. The structure of the books offers the basis for courses in the field of materials science, chemical sensors, sensor technologies, chemical engineering, semiconductor devices, electronics, and environmental control. Graduate students could also find the books useful while conducting research and trying to understand the basics of gas sensor design and functioning. 1 hope very much that in these books all will find specific information that will be of interest and use in his/her area of scientific and professional interests. 

Most aquatic oxidation reactions are attributable to well-defined chemical oxidants. As a result, model systems can be designed where second-order rate constants can be determined precisely for families of organic congeners. The comparatively high quality of these data allows mechanistic models of electron transfer to describe aquatic oxidations of environmental interest. Kinetic studies of these processes have produced many QSARs, mostly simple empirical correlations with common convenient descriptors such as the Hammett constant (a), half-wave oxidation potential ( j/2)> energies of the highest occupied molecular orbital ( HOMO), or rate constants for other oxidation reactions as descriptors (Canonica and Tratnyek, 2003). Their predictive power has lead to engineering applications in water treatment and remediation. 

Software and Online Sources of Chemical Properties. Larson et al.28 and Andren et al.16 provide a thorough listing of electronic databases and online search engines for environmental fate properties. Very useful online databases for these parameters include Syracuse Research Corporation s (SRC s) (Syracuse, NY) Environmental Fate Database (EFDB) and the Hazardous Substances DataBank available at http //toxnet.nlm.nih.gov/. The SRC Web site...
