Biodiesel from Used Oil Roland Stout
Recently three papers have appeared in this Journal discussing the properties of biodiesel fuels and their production from biological oils, either new or used. We will frustrate students if we do not discuss why laboratory scale productions of biodiesel from used oil may produce significant amounts of emulsion.

Peer Review of Chemistry Journal Articles: Collaboration across Disciplines Bozena Barbara Widanski and Debra Courtright-Nash
Organic chemistry students conducted self-designed experiments and submitted their manuscripts to English composition students who reviewed them according to journal guidelines. The results indicate that chemistry students improved their understanding of the scientific process and scientific writing.

Making Usable, Quality Opaque or Transparent Soap Suzanne T. Mabrouk
First-year and organic chemistry students will learn the chemistry of soap by making some of the eleven described formulations, which produce usable, quality bars of soap. Opaque and transparent soaps are made in two and three hours, respectively. With an introduction to formulation chemistry, organic chemistry students can devise a formulation to synthesize their own opaque soap. Many of the formulations use commonly-available fats and oils, while some formulations incorporate specialty fats and oils for therapeutic purposes, for example, to relieve dry skin or itching.

Synthesis and Physical Properties of Liquid Crystals: An Interdisciplinary Experiment Gerald R. Van Hecke, Kerry K. Karukstis, Hanhan Li, Hansford C. Hendargo, Andrew J. Cosand, and Marja M. Fox
This experiment features an investigative approach designed for the introductory science or engineering major and integrates concepts in the fields of chemistry, biology, and physics. Derived from faculty research interests, this novel experiment gives students the opportunity to draw conclusions from tests performed to illustrate the connection between molecular structure and macroscopic properties. The chemical synthesis of the compounds studied further enhances the connection between molecular structure and macroscopic physical properties. The results of two separate physical measurements, refractometry and absorption spectroscopy, are combined to calculate a microscopic, but very practical, property of chiral nematic liquidsthe pitch of the helix formed in the liquid crystalline phase.

Comment on the Hazards of Peroxide Decomposition J. C. Jones
The issue under discussionthe presence in ether of peroxides and their explosive decompositionis an important one, and the correspondence referred to is focused on laboratory safety. I believe however that an interesting point of pedagogic value can be gleaned from it.

An Organoleptic Laboratory Experiment John M. Risley
Compounds in ten different classes of organic molecules that are used in the fragrance and food industry are provided to students. Students whiff the vapors of each compound and describe the organoleptic properties using a set of terms utilized in the fragrance and food industry. A set of questions guides students to an understanding of the relationship between structure of molecules and smell.
