Palmer, S. B.; Forster, G. A. – Amer J Phys, 1970
Describes and apparatus designed to generate and detect pulsed ultrasonics in solids and liquids over the frequency range 1-20 MHz. Experiments are suggested for velocity of sound, elastic constant and ultrasonic attenuation measurements on various materials over a wide temperature range. The equipment should be useful for demonstration purposes.…

Peer reviewedWang, Joseph – Journal of Chemical Education, 1983
Describes an experiment designed to acquaint students with the theory and applications of anodic stripping voltammetry (ASV) as well as such ASV problems as contamination associated with trace analysis. The experimental procedure, instrumentation, and materials discussed are designed to minimize cost and keep procedures as simple as possible. (JM)

Peer reviewedMurray, William Henry – American Journal of Physics, 1974
Discusses the construction of a diffractometer table and four microwave models which are built of styrofoam balls with implanted metallic reflecting spheres and designed to simulate the structures of carbon (graphite structure), sodium chloride, tin oxide, and palladium oxide. Included are samples of Bragg patterns and computer-analysis results.…

Peer reviewedMak, S. Y.; Young, K. – Physics Education, 1986
Describes a simple method for determining self-inductance of non-ferromagnetic rings. Suggests fitting the ring with an auxiliary coil and using a solenoid driven with a known frequency alternating current. Amplitude change and phase shift can be measured and used to calculate inductance. Material list, calculations, and sample results are given.…
