Demonstrating Electron Transfer and Nanotechnology: A Natural Dye-Sensitized Nanocrystalline Energy Converter Greg P. Smestad and Michael Gratzel
A unique solar cell fabrication procedure has been developed using natural anthocyanin dyes extracted from berries. It can be reproduced with a minimum amount of resources in order to provide an interdisciplinary approach for lower-division undergraduate students learning the basic principles of biological extraction, physical chemistry, and spectroscopy as well as environmental science and electron transfer.

The Chemical and Educational Appeal of the Orange Juice Clock Paul B. Kelter, James D. Carr, Tanya Johnson, and Carlos Mauricio Castro-Acuña
The Orange Juice Clock, in which a galvanic cell is made from the combination of a magnesium strip, a copper strip, and juice in a beaker, has been a popular classroom, conference, and workshop demonstration for nearly 10 years. The discussion that follows considers the recent history, chemistry, and educational uses of the demonstration.

The conversion of chemical energy: Part 1. Technological examples Wink, Donald J.
When a chemical reaction occurs, the energy of the chemical species may change and energy can be released or absorbed from the surroundings. This can involve the exchange of chemical energy with another kind of energy or with another chemical system.

Redox reactions and the electropotential axis Vella, Alfred J.
An introductory discussion should not get bogged down with the problems of representing cells by standard cell diagrams and notations and instead should concentrate on the chemistry of galvanic cells and the use of these cells in describing the concepts of redox chemistry.
