Helping Students Assess the Relative Importance of Different Intermolecular Interactions Paul G. Jasien
A semi-quantitative model has been developed to estimate the relative effects of dispersion, dipoledipole interactions, and H-bonding on the normal boiling points for a series of simple, straight-chain organic compounds. Application of this model may be useful in addressing student misconceptions related to the additivity of intermolecular interactions.

Hydrophilic Inorganic Macro-Ions in Solution: Unprecedented Self-Assembly Emerging from Historical "Blue Waters" Tianbo Liu, Ekkehard Diemann, and Achim Müller
The behavior of supramolecular structures in solution is different from that of simple ions, polymers, surfactant micelles, and colloids. New research involving polyoxometalates, which are fully hydrophilic but tend to self-associate into macro-ionic structures, may change our understanding of inorganic ionic solutions.

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.

Effects of Solution Physical Properties on Copper and Chromium Signals in Flame Atomic Absorption Spectrometry Fàbio R. P. Rocha, Joaquim A. Nòbrega
Instrumental techniques, such as flame atomic absorption spectrometry (FAAS), are frequently used in chemical analysis. Independently of the technique used, the chemical principles must be considered to assure that the analytical results are correct.

Illustration of Mn and Mw in chain-growth polymerization using a simplified model: An undergraduate polymer chemistry laboratory exercise Snyder, Donald M.
This exercise helps to attain three pedagogical objectives. Laying out the chains illustrates that a polymer is composed of a mixture of various chain lengths, the random-number assembly of the chain illustrates the statistical aspects of chain growth, the limited number of chains and chain length of the chain allows direct calculation of the number of chains and the weight averages of the chains.

Chemical origins of color Orna, Mary Virginia
Color is one of the few disciplines that cuts across the boundaries of art, biology, physics, psychology, chemistry, geology, mineralogy, and many other fields. There is hardly an object or a substance in nature that is not colored and virtually every commercially marketed item today is either deliberately colored or de-colored.
