Developments in analytical chemistry were made using acoustically levitated small volumes of liquid to study enzyme reaction kinetics and by detecting volatile organic compounds in the gas phase using single-walled carbon nanotubes. Experience gained in engineering, electronics, automation, and software development from the design and…

Separations have played a major role in the history of chemical engineering and will continue to be important. Since separations have always been a major cost item in the process industries, they have always been a critical key to successful commercialization. First, while reviewing the history of separation processes we will observe that many…

As the General Motors Corporation shuts assembly plants and veers toward bankruptcy, the lonely remnants of one of its top technological achievements--the first modern mass-produced electric car--lie scattered across a few dozen American college campuses. GM produced and leased to customers more than 1,000 "EV1" automobiles beginning in 1996. In…

In order to address some of the challenges facing engineering education, namely the demand that students be better prepared to practice professional as well as technical skills, we have developed an intervention consisting of equipment, assessments and a novel pedagogy. The equipment consists of desktop-scale replicas of common industrial…

Most chemical engineering programs that offer M.S. and Ph.D. degrees have a common seminar series for all the graduate students. Many would agree that seminars lack student interest, leading to ineffectiveness. We questioned the possibility of adding value to the seminar series by incorporating non-technical topics that may be more important to…

The preponderance of the evidence from the engineering education literature demonstrates that inductive teaching methods are more effective than deductive approaches. When students are already familiar with the fundamentals of a topic, however, deductive approaches may make more sense. This paper discusses the implementation of a combination of…

This paper describes an experiment performed by the fourth year chemical engineering students in the process control laboratory at the University of Waterloo. The objective of this experiment is to test the capabilities of a constrained Model Predictive Controller (MPC) to control the operation of a Double Pipe Heat Exchanger (DPHE) in real time.…

The pressure on world-wide manufacturing industries to meet tougher demands and regulations has forced companies to focus on improving manufacturing using tools like process automation. This focus requires better-prepared students. The process control course of the Department of Chemical Engineering at the University of Puerto Rico at Mayaguez has…

For some time there has been a focus in higher education research towards understanding the student experience of learning. This article presents a narrative analysis of the experience of a teacher who re-entered the learning world of undergraduate students by enrolling in a challenging chemical engineering course. The analysis identifies multiple…

Chemical engineering students begin their studies of mechanics in a department of physics where they are introduced to the mechanics of Newton. The approach presented by physicists differs in both perspective and substance from that encountered in chemical engineering courses where Euler's laws provide the foundation for studies of fluid and solid…

In engineering careers courses, differential equations are widely used to solve problems concerned with modelling. In particular, ordinary differential equations (O.D.E.) linear systems appear regularly in Chemical Engineering, Food Technology Engineering and Environmental Engineering courses, due to the usefulness in modelling chemical kinetics,…

A reference electrode is one of the prerequisites of electrochemical investigations. Many electrodes are commercially available but are expensive and prone to accidental breakage by students. Here we report a simple, easy-to-fabricate, inexpensive, reliable, unbreakable, and reproducible Ag/AgCl reference electrode. The empty barrel of a…

Oral interviews in focus groups and written surveys were conducted with 877 men and women, including administrators, faculty members, postdoctoral associates, and graduate students, during one-day site visits to chemistry and chemical engineering departments at 28 Ph.D.-granting institutions. This report is a preliminary review of the perceptions…

Inter-group peer evaluation through wikis was implemented as a method for senior capstone design teams to improve writing and the critical evaluation of data. Each group was evaluated by peers using a qualitative discussion and evaluated quantitatively by instructors. Students had an increased interest in contributing to online knowledge centers,…

An academic and professional development course has been introduced to help first-year chemical engineering students to deal proactively with the transition from secondary school to university and to develop professional skills. The course uses the Myers-Briggs Type Indicator (MBTI) as a personality model to facilitate skills development and many…
