Bioorganic Chemistry: Designing Peptides with Defined Folding Properties Caroline R. Pharr, Erik B. Hadley, and William C. Pomerantz
This Today's Science for Tomorrow's Scientists (TSTS) tutorial introduces current scientific research involving the design of molecules with well-defined folding properties, including short polymer chains of β-amino acids (β-peptides) that display antibiotic activity or form liquid crystals.

Stilling Waves with Ordered Molecular Monolayers Ed Vitz
The amazing ability of a film of oil one molecule thick to dissipate the relatively large energy of water waves can be readily demonstrated, but an explanation of the effect has been elusive until recently.

Determination of Sugar Content in Commercial Beverages by Density: A Novel Experiment for General Chemistry Courses Susan K. Henderson, Carol A. Fenn, and John D. Domijan
A laboratory experiment based on the determination of density, suitable for introductory-level chemistry courses, is described. The experiment provides students an opportunity to develop skills in weighing, preparing solutions, pipetting, constructing and using a calibration curve, and proper use of significant figures.
