We report the design of a low-cost electrochemical workstation and open-source graphical user interface capable of performing a variety of electrochemical methods in an undergraduate teaching laboratory. The instrument--based on the popular Arduino microcontroller board--can be constructed from common components for $40 USD. The modular design of…

This paper outlines a comprehensive teaching laboratory course program that centers on titration analysis, a timeless and essential technique in analytical chemistry spanning various disciplines, such as environmental science, medicine, and industry. In these fields, titration analysis is paramount for determining the concentrations of substances…

Laboratories are an indispensable part of the fundamental sciences. Laboratories are important learning environments that enable students to relate events to daily life as well as being places where theoretical knowledge is implemented. The present study investigated the knowledge and usage level of preservice biology teachers regarding lab…

Because she had been blind since birth, we knew that our new student, Cricket, would be unable to make the necessary measurements needed to get any meaningful lab data while all of the other students would be able to use highly accurate commercial Vernier calipers. All we had on loan for Cricket was a Brailled plastic tactile meter stick with low…

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…

Electrospinning has been used to create nanofibers for filtration devices, tissue engineering, and protective clothing. Although electrospinning is now widely studied, because of the expensive equipment required and the advanced nature of this topic, it is not commonly found in high school science labs. Through grants from the Ohio State…

This article discusses factors in the design, commissioning, project management, and intellectual property protection of developments within a new clinical anatomy facility in the United Kingdom. The project was aimed at creating cost-effective facilities that would address widespread concerns over anatomy teaching, and support other activities…
