Dewi Ayu Kencana Ungu; Mihye Won; David F. Treagust; Mauro Mocerino; Henry Matovu; Chin-Chung Tsai; Roy Tasker – Journal of Chemical Education, 2023
Magnetic molecular models help students explore molecular structures and interactions. In this study, we investigated how pairs of students used magnetic models to explore hydrogen bonding and the 6-fold symmetry of snowflakes. Fourteen first-year students enrolled in a chemistry unit participated in pairs. Students' interactions with the magnetic…

Kaixin Liu; Shuquan Huang; Yangxin Jin; Jason Chun-Ho Lam – Journal of Chemical Education, 2023
The rapid growth of personal electronics has promoted a surge of e-waste worldwide. Among the e-waste stream, waste printed circuit boards (WPCBs) contain a lot of recyclable valuable metals that can incentivize the recycling operation when recovered. This pedagogical exercise demonstrates a simple electrocatalytic metal recovery strategy that…

Si-Ke Chen; Xiao-Jie Ju; Jie Wei; Wei Wang; Liang-Yin Chu – Journal of Chemical Education, 2023
Previous educational articles on microfluidic technology mainly focused on continuous microfluidics, so we set up an undergraduate laboratory experiment to introduce droplet microfluidics to students. Students can understand the concept of microfluidic channels and the principles of droplet microfluidics, prepare polydimethylsiloxane (PDMS)…

Alisha R. Szozda; Peter G. Mahaffy; Alison B. Flynn – Journal of Chemical Education, 2023
New resources have recently been emerging for educators to implement systems thinking (ST) in chemistry education, including a proposed set of ST skills. While these efforts aim to make ST implementation easier, little is known about how to assess these skills in a chemistry context. In this study, we investigated ST skills employed by students…

Takahiro Suzuki; Misaki Fujino; Yoji Yamada – Journal of Chemical Education, 2023
A laboratory experiment is proposed, wherein students fabricate a glucose fuel cell, use it to operate a solar motor, and investigate its performance. First, a fuel cell catalyst is prepared by plating palladium on two nickel wire meshes using an aqueous palladium chloride solution containing sodium dodecyl sulfate, an anionic surfactant that…

Adrian R. Hilts; Jason Cooke – Journal of Chemical Education, 2023
The addition of a small excess of triethyl orthoformate to an alcoholic mixture of NiCl[subscript 2]·6H[subscript 2]O and triphenylphosphine (PPh[subscript 3]) results in an increase in the typical isolated yield of [NiCl[subscript 2](PPh[subscript 3])[subscript 2]] from below 50% to over 85%. The impact of water when present in the reaction…
