Horikoshi, Ryo; Shirotani, Dai; Shioyama, Hiroshi – Journal of Chemical Education, 2022
Buckminsterfullerene (C[subscript 60]), along with diamond and graphite, appears in many chemistry textbooks as an example of an allotrope of carbon. This communication describes a hands-on activity to explore the characteristic structure of C[subscript 60] through the construction of a structural model using transistors and plastic tubes…

Bharti, Neelam; Singh, Shailendra – Journal of Chemical Education, 2017
As an emerging technology, three-dimensional (3D) printing has gained much attention as a rapid prototyping and small-scale manufacturing technology around the world. In the changing scenario of library inclusion, Makerspaces are becoming a part of most public and academic libraries, and 3D printing is one of the technologies included in…

Blanck, Harvey F. – Journal of Chemical Education, 2012
Naturally occurring gravity currents include events such as air flowing through an open front door, a volcanic eruption's pyroclastic flow down a mountainside, and the spread of the Bhopal disaster's methyl isocyanate gas. Gravity currents typically have a small height-to-distance ratio. Plastic models were designed and constructed with a…

Hladky, Paul W. – Journal of Chemical Education, 2007
Random-climb models enable undergraduate chemistry students to visualize polymer molecules, quantify their configurational properties, and relate molecular structure to a variety of physical properties. The model could serve as an introduction to more elaborate models of polymer molecules and could help in learning topics such as lattice models of…
