Preparation of Dppe-Stabilized Gold Nanoparticles Keenan E. Dungey, David P. Muller, and Tammy Gunter
This laboratory experiment is designed to give upper-level undergraduate students experience in nanotechnology by synthesizing and characterizing gold nanoparticles. The two-to-four week project begins with the synthesis of the ligand, 1,2-bis(diphenylphosphino)ethane (dppe). Students then use the dppe to prepare gold nanoparticles. The products are analyzed by IR and NMR spectroscopies and comparisons are made between the bound and unbound ligand.

Preparation and Properties of an Aqueous Ferrofluid Patricia Enzel, Nicholas B. Adelman, Katie J. Beckman, Dean J. Campbell, Arthur B. Ellis, and George C. Lisensky
This paper describes a simple synthesis of an aqueous-based ferrofluid that may be used in an introductory science or engineering laboratory. This paper also describes a method for repelling both oil- and water-based ferrofluid from solid surfaces that would otherwise be stained by the fluid. Finally, a demonstration of the interaction between ferrofluid and magnetic fields, in which ferrofluid is induced to leap upward by a stack of magnets, is described.

Efficient Light-to-Electrical Energy Conversion: Nanocrystalline TiO2 Films Modified with Inorganic Sensitizers Gerald J. Meyer
The basic features of the sensitized nanocrystalline solar cell are presented. An emphasis is placed on the molecular electron transfer processes that convert and inhibit the conversion of visible photons to an electrical current. New strategies for improving this technology and future research directions are also discussed.

Polymer additives: III. Surface property and processing modifiers Stevens, Malcolm P.
The final installment of a three-part paper on the subject of polymer additives. Some of the properties these additives bring to polymers are: anti-blocking agents, anti-fogging agents, antistatic agents, coupling and releasing agents, blowing and crosslinking agents, defoaming agents, emulsifiers, and heat stabilizers.
