The June 2016 issue of the Journal of Chemical Education is now available online to subscribers. Topics featured in this issue include: visualizations for chemistry teaching and learning, periodic table resources for teaching visually impaired students, biochemistry in the classroom and laboratory, spectroscopy in the laboratory, commentaries on analytical chemistry topics, resources for teaching, distilling the archives: guided-inquiry experiments.

Editorial

In the Editorial Communicating Chemistry in Informal Environments: A Framework for Chemists, Mary M. Kirchhoff of the Education Division of the ACS discusses a recent report by the National Academies, Effective Chemistry Communication in Informal Environments. This freely available resource offers a framework to guide and encourage chemists in engaging successfully with the public.

Visualizations for Chemistry Teaching and Learning

Visualizing Molecular Chirality: Cover Feature

The cholesteric liquid crystal phase is a fluid in which rod-like molecules are orientationally ordered, with an overall helical twist. Such phases can be induced by adding a chiral solute to an (achiral) nematic liquid crystal. With sufficiently powerful chiral dopants, the pitch of the twist is on the order of the wavelength of visible light, and the phase will selectively reflect circularly polarized light. This property allows for a straightforward macroscopic visualization of molecular chirality. In Visualizing Molecular Chirality in the Organic Chemistry Laboratory Using Cholesteric Liquid Crystals, Maia Popova, Stacey Lowery Bretz, and C. Scott Hartley describe a simple experiment in which students synthesize a single enantiomer of a chiral dopant and then dissolve it in a commercially available liquid crystal host. A film on a glass slide allows students to deduce the absolute configuration of their starting material by observing the reflection of light through the filters in disposable glasses for 3D video.
