Ramos, L. M.; Reis, C. R. N.; Calheiro, L. B.; Goncalves, A. M. B. – Physics Education, 2021
Using a joystick module, we followed the movement of a chaotic magnetic pendulum. The pendulum bar was attached to a joystick that served as a pivot point and biaxial angular motion sensor. Using an Arduino board, we could follow the position as a function of time along both the "x" and "y"-axis and draw a graph showing the…

Flexible and Modular 3D-Printed Peptide Models
Peer reviewed Peer reviewed
Direct linkDirect link
Kerwin, Sean M. – Biochemistry and Molecular Biology Education, 2019
A flexible and modular peptide modeling set was designed using freely available software tools. The set consists of space-filling models of all 20 naturally occurring amino acid side chains and a modular kit for constructing peptides employing C-alpha carbons and amide bond groups. Connectors that allow free rotation about phi and psi angles on…

Peterson, Celeste N.; Tavana, Sara Z.; Akinleye, Olukemi P.; Johnson, Walter H.; Berkmen, Melanie B. – Biochemistry and Molecular Biology Education, 2020
Biology and biochemistry students must learn to visualize and comprehend the complex three-dimensional (3D) structures of macromolecules such as proteins or DNA. However, most tools available for teaching biomolecular structures typically operate in two dimensions. Here, we present protocols and pedagogical approaches for using immersive augmented…
