This paper describes a simple, cost-effective experiment which introduces students to drug delivery and modeling using alginate beads. Students produce calcium alginate beads loaded with drug and measure the rate of release from the beads for systems having different stir rates, geometries, extents of cross-linking, and drug molecular weight.…

The principles of sustainable development have been integrated in chemical engineering education by means of an environmental management system. These principles have been introduced in the teaching laboratories where students perform their practical classes. In this paper, the implementation of the environmental management system, the problems…

Sustainability has emerged as a primary context for engineering education in the 21st Century, particularly the sub-discipline of chemical engineering. However, there is confusion over how to go about integrating sustainability knowledge and skills systemically within bachelor degrees. This paper addresses this challenge, using a case study of an…

Reviews recent developments in synthetic organic sonochemistry, focusing on reactions involving metals. Cites important historical findings, discusses cavitation effects, and describes important reactions. (JM)

Scientific ideas of the biological laboratory are turned into economic realities in industry only after several problems are solved. Economics of scale, agitation, heat transfer, sterilization of medium and air, product recovery, waste disposal, and future developments are discussed using aerobic respiration as the example in the scale-up…

Describes stochastic models. Discusses the rationale for stochastic analysis and modeling, and provides a master equation for the models with respect to chemical processes. Lists 29 references. (YP)

Discusses direct chemical information that can be obtained from modern nuclear magnetic resonance (NMR) methods, concentrating on the types of problems that can be solved. Shows how selected methods provide information about polymers, bipolymers, biochemistry, small organic molecules, inorganic compounds, and compounds oriented in a magnetic…

Presents an imaginary dialogue between: (1) a student in search of a research project and (2) a professor in need of a research assistant. Various issues in engineering, chemical engineering, engineering education, and engineering research are addressed during the hypothetical discussion. (Author/JN)

Presents a framework identifying the molecular level assumptions underlying many thermodynamic models. Tests the assumptions using theory and computer simulation to develop better assumptions. (YP)

Discusses nuclear power and the consequences of a nuclear accident. Covers issues ranging from chemical process safety to risk management of chemical industries to the ethical responsibilities of the chemical engineer. (Author/ASK)

Presents six problems from an alternative approach to homework traditionally given to follow-up lectures. Stresses the advantage of longer term exercises which allow for creativity and independence on the part of the student. Problems include: "System Model,""Open-Loop Simulation,""PID Control,""Dahlin…

To illustrate the behavior of polymeric fluids and in what respects they differ from Newtonian liquids, an experiment was developed to account for the shear-rate dependence of non-Newtonian fluids. Background information, procedures, and results are provided for the experiment. Useful in transport processes, fluid mechanics, or physical chemistry…

Shows that the principles learned in the study of mass transport, thermodynamics, and kinetics associated with electrochemical systems can be applied to the transport and reaction processes taking place within a semiconductor. Describes impedance techniques and provides several graphs illustrating impedance data for diverse circuit systems. (YP)

Discusses a course focusing on fluid mechanics and physical chemistry of suspensions. Describes the main themes of the lectures and includes a list of course outlines. Possible textbooks and many journal articles are listed. (YP)

Presents a problem related to mass balances for checking the consistency of measured data from a process. Provides the solution to the problem with diagrams and calculation tables. (YP)
