Gold nanoparticles (AuNPs) are textbook model systems to introduce "Nanomaterials" and "Nanotechnology" to students and laypersons. AuNPs are also suitable materials to raise awareness about the "Green Chemistry" principles. The unique optical and catalytic properties of nanosized gold make it ideal to timely develop…

Diversity in teams has been shown to enhance creativity and innovation, particularly in teams where all members felt a sense of belonging. Creating an inclusive environment in a lab setting that provides a sense of belonging to all is challenging. This is particularly true in a field like Biomedical Engineering/Bioengineering where diversity is…

Protein engineering represents a modern approach to generate novel proteins for the different fields of biotechnology. Here, we report about an 8-day laboratory activity in which students generate enzyme variants to degrade the herbicide glyphosate. The students conduct a true research experiment in an important field (bioremediation by novel,…

A simple apparatus is described which serves as a materials testing laboratory. Bolts are placed in it and subjected to tensile and torsional stress while being tightened. The tensile and torsional stress and strain can be measured, which enables the determination of several mechanical properties of the bolt material, including Young's…

As part of a biomechanics course aimed at both upper-division Biology and Physics majors, this laboratory exercise introduces students to the ingenious ways in which organisms vary the composition and form of support and defensive structures such as bone and shell to maximize their strength while minimizing the energetic cost needed to produce…

When students complete a lab experiment at home or in a staffed lab on campus, they come to class better able to explain what they have done and why they think the approach is correct, and to provide explanations or questions about any problems they encountered. What is so cool is that the learning experience has all the key aspects of the…

A technique for automatic error analysis using interval mathematics is introduced. A comparison to standard error propagation methods shows that in cases involving complicated formulas, the interval approach gives comparable error estimates with much less effort. Several examples are considered, and numerical errors are computed using the INTLAB…

This paper presents interactive power electronics educational tools. These interactive tools make use of the benefits of Java language to provide a dynamic and interactive approach to simulating steady-state ideal rectifiers (uncontrolled and controlled; single-phase and three-phase). Additionally, this paper discusses the development and use of…

This paper discusses an experiment-based approach to teaching an advanced control engineering syllabus involving controlled plant analysis and modeling, control structures and algorithms, real-time laboratory experiments, and their assessment. These experiments are structured around the representative case of the longitudinal slip control of an…

Physics is essential for students who want to succeed in science and engineering. Excitement and interest in the content matter contribute to enhancing this success. We have developed a laboratory experiment that takes advantage of microwave ovens to demonstrate important physical concepts and increase interest in physics. This experiment…

The University of Waterloo, Waterloo, ON, Canada, is home to North America's first undergraduate program in nanotechnology. As part of the Nanotechnology Engineering degree program, a scanning probe microscopy (SPM)-based laboratory has been developed for students in their fourth year. The one-term laboratory course "Nanoprobing and…

Nanoscale science and engineering are disciplines that examine the unique behaviors and properties of materials that emerge at the size range of 1 to 100 nanometers (a billionth of a meter). Nanobiotechnology is a sub-discipline of nanoscience that has arisen more recently. Nanobiotechnology is already impacting the fields of healthcare and…

While looking for labs for his pre-engineering class, the author came across an idea for a marine engineering project from the Future Scientists and Engineers of America website. The author thought the lab looked fun, and it was not too expensive. These were two important criteria as he chose labs for the class. Another important criteria he had…

Higher education institutions and scientific funding agencies are emphasizing international projects that involve the integration and synergy between research groups, particularly if different disciplines are involved. Students with an education that reflects these trends will have more tools to succeed in the future, but it is challenging to…

This article describes experiments for an undergraduate instrumental analysis laboratory that aim to observe individual double-stranded DNA (dsDNA) molecules using fluorescence microscopy and atomic force microscopy (AFM). dsDNA molecules are observed under several different conditions to discuss their chemical and physical properties. In…
