Direct linkLabbe, Amelia B.; Bagshaw, Clive R.; Uttal, Lisa – Journal of Chemical Education, 2020
Microplastic contamination of the environment is a major concern but detecting such contamination presents a challenge, particularly for particles <0.1 mm in size. Community scientists and students who participated in a plankton monitoring program and routinely examined samples of seawater using brightfield microscopy, often found fragments and…

Koshut, W. J.; Arnold, A. M.; Smith, Z. C.; Wright, Z. M.; Sydlik, S. A. – Journal of Chemical Education, 2019
This work describes a semester-long learning module designed to equip students with the analytical and practical skills necessary to be successful in an interdisciplinary polymer research environment. This learning module combines laboratory experiments involving both synthesis and materials characterization with lectures in polymer theory, and…

Dickson-Karn, Nicole M. – Journal of Chemical Education, 2017
A multi-instrument approach has been applied to the efficient identification of polymers in an upper-division undergraduate instrumental analysis laboratory course. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) is used in conjunction with differential scanning calorimetry (DSC) to identify 18 polymer samples and…

Kusch, Peter – Journal of Chemical Education, 2014
An experiment for the identification of synthetic polymers and copolymers by analytical pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) was developed and performed in the polymer analysis courses for third-year undergraduate students of chemistry with material sciences, and for first-year postgraduate students of polymer sciences. In…

Vasanthan, N. – Journal of Chemical Education, 2012
Polymer science represents an important area in industrial and research laboratories for chemists and material scientists. However, experiments involving polymers are uncommon in chemistry and material science curricula; therefore, an experiment involving polymers has been developed. This experiment has been used to teach fabrication of polymer…

Bellamy, Michael K. – Journal of Chemical Education, 2010
The internal standard method is widely applied in quantitative analyses. However, most analytical chemistry textbooks either omit this topic or only provide examples of a single-point internal standardization. An experiment designed to teach students how to prepare an internal standard calibration curve is described. The experiment is a modified…
