Roman, Harry T. – Technology and Engineering Teacher, 2013
The ability to remotely inspect equipment of an aging infrastructure is becoming of major interest to many industries. Often the ability to just get a look at a piece of critical equipment can yield very important information. With millions of miles of piping installed throughout the United States, this vast network is critical to oil, natural…

Cesin-AbouAtme, Tania; Lopez-Almeida, CelesteG.; Molina-Labastida, Geronimo; Ibanez, Jorge G. – Journal of Chemical Education, 2021
Due to social distancing constraints during the COVID-19 pandemic, several experiments were designed in the Fall 2020 and Spring 2021 semesters in our Electrochemistry and Corrosion elective course to demonstrate electrochemical phenomena and applications at the students' homes with a kit sent by the school. We report here a student-designed…

Andrews, Steven S.; Tretton, James – Journal of Chemical Education, 2020
Circular dichroism (CD) is the differential absorption of left and right circularly polarized light. It arises from molecular electron oscillations that are driven by both the light's electric and magnetic fields, where the effects are in phase for one circular polarization and out of phase for the other. We describe these interactions, which have…

Ürek, Handan; Çoramik, Mustafa – Acta Educationis Generalis, 2022
Introduction: Science courses involve a wide range of content. The benefits of science education become clear when science is applied to daily life because science has the capability of raising the quality of life by eliminating a variety of problems. Accordingly, as technological advances are made, daily life applications are frequently refreshed…

Baptista, Vander – Advances in Physiology Education, 2015
From a Cartesian perspective of rational analysis, the electric potential difference across the cell membrane is one of the fundamental concepts for the study of physiology. Unfortunately, undergraduate students often struggle to understand the genesis of this energy gradient, which makes the teaching activity a hard task for the instructor. The…

Sanchez-Viesca, Francisco; Gomez, Maria Reina Gomez; Berros, Martha – Journal of Chemical Education, 2011
There are still gaps in the theory of supposedly well-known chemical reactions. For example, there is no explanation why there is a notorious preponderance of one of the expected isomers in some electrophilic aromatic substitutions. The preferred ortho orientation of acetyl nitrate has been used widely to obtain ortho nitro compounds; however,…

This article describes the projects on solar hydrogen powered vehicles using water as fuel conducted by teams at Brooklyn Technical High School. Their investigations into the pure and applied chemical thermodynamics of hydrogen fuel cells and bio-inspired devices have been consolidated in a new and emerging sub-discipline that they define as solar…

Klara, Kristina; Hou, Ning; Lawman, Allison; Wu, Liheng; Morrill, Drew; Tente, Alfred; Wang, Li-Qiong – Journal of Chemical Education, 2014
A simple, affordable hydrogen proton exchange membrane (PEM) fuel cell laboratory was developed through a collaborative effort between faculty and undergraduate students at Brown University. It has been incorporated into the introductory chemistry curriculum and successfully implemented in a class of over 500 students per academic year for over 3…

Ingram, Jay; Cangemi, Joseph – Education, 2012
When people think of emotions, usually they think of different states of being, such as happiness, sadness, or anger. However, emotions generate very powerful chemicals that can create positive feelings, such as motivation and enthusiasm, or they can create more negative responses, such as offending and even attacking others. When an emotionally…

Basken, Paul – Chronicle of Higher Education, 2009
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…

Chien, Sen-I; Su, Chaochin; Chou, Chin-Cheng; Li, Wen-Ren – Journal of Chemical Education, 2018
The present study describes the design of a simple teaching module for each student to fabricate a dye-sensitized solar cell (DSSC) that could power a small fan motor. The significance of this laboratory exercise is to stimulate students' motivation by visualizing the light being converted into electricity, which is then switched over to kinetic…

Vidal-Iglesias, Francisco J.; Solla-Gullon, Jose; Rodes, Antonio; Herrero, Enrique; Aldaz, Antonio – Journal of Chemical Education, 2012
The goal of the present laboratory experiment is to deepen the understanding of the Nernst equation and some other concepts that are essential in electrochemistry. In this practical laboratory session, students first learn that the equilibrium potential of an electrode is related to the difference between two equilibrium inner electric potentials…

Montrezor, L. H. – Advances in Physiology Education, 2014
Medical school students are expected to learn many subjects at the same time. As a result, they often experience stress and find it difficult to cope with the curriculum. In addition, some first-year students find theory and practical classes to be monotonous. One of the difficulties faced by faculty members is, therefore, to maintain student…
