This report describes the implementation of a laboratory exercise for an advanced biochemistry or enzyme kinetics class at the undergraduate or graduate level, designed to improve understanding of protein conformational changes associated with the binding of a ligand. Students measure the fluorescence changes induced by the conformational…

In this work, two exercises are described that are designed to teach students about the evolution and behavior of the electronic bands of graphene and bilayer graphene. These exercises involve performing extended Hückel molecular orbital theory calculations on polyacenes and polycyclic aromatic hydrocarbons. In the first exercise, students…

This paper reports on a case study of a project-focused introduction to big data science course. The pedagogy of the course leveraged boundary theory, where students were positioned to be at the boundary between a client's desire to understand their data and the academic class. The results of the case study demonstrate that using live clients…

An upper-level undergraduate or beginning graduate project is described in which students obtain the Lennard-Jones 6-12 potential parameters for Ne[subscript 2] and Ar[subscript 2] from ab initio calculations and use the results to express pairwise interactions between the atoms in clusters containing up to N = 60 atoms. The students use simulated…

Reviewed is the use of the Thin-Film Mercury Electrode for anodic stripping voltammetry, simple voltammetry of solution cations and cathodic stripping voltammetry for the determination of an environmentally important molecule, thiourea. The construction of a simple potentiostat and applications for student laboratory courses are included. (CW)

Described is the separation of dyes using a conventional liquid chromatographic pump and a glass column. Included are the preparation of the column and dye separations. (CW)

Activities using the same historical case study can be designed for courses of varying degrees of proficiency by altering the format to suit each academic level. The case of Isidro Mejia, a construction worker who had six nails accidentally shot into his head from a nail gun, is the basis for a series of case study exercises. (Contains 4 figures.)

Reports on the session at the New England Association of Chemistry Teachers meeting on chemistry laboratories in March 1987. Speakers included Leonard K. Nash and Audrey Champagne on values and goals; Howard Ende on regulation; Stanley Smith and Jerry Bell on the uses of computers; and Miles Pickering on the human dimension. (CW)

Reported are the results of a survey conducted to identify which analytical methods are most commonly used in nonacademic analytical laboratories. Laboratory supervisors' ratings of various aspects of chemical education are included. (CW)

Considers the applicability of the simple emersion/weight-gain method for predicting diffusion coefficients, solubilities, and permeation rates of chemicals in polymers that do not undergo physical and chemical deterioration. Presents the theoretical background, procedures and typical results related to this activity. (CW)

Discussed are four major advantages to the use of microscale laboratories for teaching chemistry. Included are effects on waste generation, laboratory safety, reagent variety, and laboratory efficiency. (CW)
