Cover: Nanochemistry

Photonic crystals are structures that form their color by diffraction rather than by electronic transition. In Emulsion Polymerization, Size Determination, and Self-Assembly of Monodispersed Poly(methyl methacrylate) Nanospheres for Photonics, George Lisensky, Fabian Dauzvardis, Jiaqi Luo, Jacob Horger, and Emma Koenig present a laboratory experiment in which students create their own synthetic opal (microfuge tubes) to template an inverse opal (background SEM image) while using two forms of polymerization. During the experiment, students synthesize ~250 nm poly(methyl methacrylate) (PMMA) spheres. The spheres are self-assembled by sedimentation and capillary evaporation, and these close-packed structures exhibit opalescence because the repeat distance is similar to the wavelength of light. Students gain exposure to polymers, nanochemistry, photonics, and self-assembly to measure the size of the PMMA nanospheres by four different methods. This experiment provides students with opportunities to collaborate and work on multiple related experiments at once.

From the Archives: Using Dice To Let the Chemistry Learning Roll

The use of dice for teaching has appeared in the Journal since its earliest issues, including the game “chemical dice” as described in a 1935 article Games for a Chemist’s Party by William E. Caldwell:

A second game which has been found amusing, and which is not original with us, is “chemical dice”. Symbols of metals may be placed on the faces of each of three wooden cubes, each face having one symbol. Symbols for non-metals or non-metallic radicals are placed on faces of three other cubes. The six dice are rolled some given number of times and the player tries to match up top faces to obtain molecular formulas. Fun and trouble for the player may be caused by putting symbols of rare gas or rare earth elements on some facets. Sub-numerals to cause valence difficulty may be used beneath symbols.

Eighty-five years later, this issue includes Rolling the Dice: Modeling First- and Second-Order Reactions via Collision Theory Simulations in an Undergraduate Laboratory in which Jessica Iribe, Terianne Hamada, Hyesoo Kim, Matt Voegtle, and Christina A. Bauer use dice to teach kinetic principles. Other articles found in the intervening years that use dice in a variety of ways to teach chemistry concepts include:
