Examines topics related to classical solution thermodynamics, considering energy, enthalpy, and the Gibbs function. Applicable mathematical equations are introduced and discussed when appropriate. (JN)

Analyzes steady-state multiplicity in chemical reactors, focusing on the use of two mathematical tools, namely, the catastrophe theory and the singularity theory with a distinguished parameter. These tools can be used to determine the maximum number of possible solutions and the different types of bifurcation diagrams. (JN)

Degrees of freedom analysis, the nature of Sorel's equations and sparsity patterns, equation-tearing strategies, simple and complex separation operations, and the complete tearing method are among the topic areas addressed in this discussion of equilibrium-stage operations, with and without computer applications. (JN)

Current chemical engineering textbooks teach that the driving force for diffusive mass transport in ideal solutions is the gradient in mole fraction. This is only true for ideal solution liquids. Therefore, it is shown that the appropriate driving force for use with ideal gases is the gradient in partial pressure. (JN)

Discusses the nature of semiconductor chemical reactor engineering, illustrating the application of this engineering with research in physical vapor deposition of cadmium sulfide at both the laboratory and unit operations scale and chemical vapor deposition of amorphous silicon at the laboratory scale. (JN)

Carries on from an article about the context for assessment of problem solving skills. Describes other forms of evidence in problem solving skill besides the options given in the previous article. Lists eight forms of evidence related more directly to the problem solving process. Analyzes the relationship among some of these suggested forms of…

Highlights findings from the National Science Foundation's "1982 Postcensal Survey of Natural and Social Scientists and Engineers." Indicates that, from 1972 to 1982, employment of scientists and engineers increased 4 percent per year. However, these employment gains do not reflect the picture for chemists or chemical engineers. (JN)

The job situation for new chemical engineers with bachelor's degrees is continuing to reflect the gradual improvement that began in 1983. However, companies are looking for graduates with technical expertise as well as marketing, sales, or communications skills. Smaller classes may lead to shortages of chemical engineering graduates in the future.…

Details the chemical engineering program at Northwestern University and factors that contribute most to its success. Also considers whether the quality of public and private education in this field differ significantly. Discusses BS degree production, measures of program quality, trends, and challenges to maintenance of faculty effectiveness.…

Describes experiences using the World Wide Web (WWW) at Rensselaer Polytechnic Institute. Offers teaching tips, describes problems encountered, and considers possible changes in teaching. Notes that assignments with the WWW in courses in environmental and chemical engineering are popular, but the best ways of using the WWW for teaching are still…

Discusses employment prospects for chemists and chemical engineers working in energy research and development (R & D) based on the Department of Energy report "Energy-related Manpower, 1983." Indicates that conclusions related to R & D funding and employment are uncertain because of the difficulty in predicting future changes in…

Chemical reaction rates can be controlled by varying composition of miniscule clusters of metal atoms. These bimetallic catalysts have had major impact on petroleum refining, where work has involved heterogeneous catalysis (reacting molecules in a phase separate from catalyst.) Experimentation involving hydrocarbon reactions, catalytic…

Presents salary data and findings from the 1983 annual survey of the economic status of American Chemical Society members. Indicates that unemployment is down, median salaries are 5 percent higher than last year for Ph.D chemists (3 percent for non-Ph.Ds), and that raises are moderate compared to previous years. (JN)

Discusses a biochemical engineering program for undergraduate and graduate students. Describes three university programs including the goals, courses, and problems involved. (YP)

The approach taken to chemical engineering education at New Mexico State University is described in this report. The curriculum model for its undergraduate and graduate program emphasizes both content and skill development. Involvement in tasks related to ongoing research projects is stressed and serves as the basis for course assignments at the…
