Describes a simple experiment using an inexpensive RCA 931A photomultiplier, in which a measurement of the secondary electron emission coefficient is measured at the last dynode. (MLH)

Describes the chemistry of dyeing, including acid, basic, vat, and disperse dyes. Includes laboratory experiments. (MLH)

Describes eleven laboratory experiments, including the catalytic effect of copper in zinc-acid reaction; a study of the rate of polymerization of some aldehydes; and a demonstration automatic potentiometric titrator. (MLH)

Discusses a laboratory experiment in which uranium is isolated by the reduction of uranyl acetate. (MLH)

Describes the synthesis of a sweetening compound that requires seven laboratory periods of three-hours duration. (MLH)

Describes an entry into the synthesis of the cyclopropenone series that is designed for the undergraduate organic chemistry laboratory. (MLH)

Describes a laboratory procedure for separating a mixture of plastics representative of scrap plastic using various solvents and solubility techniques. (MLH)

Described is an advanced undergraduate physics laboratory experiment for determining an area, and bandwidth-independent parameter, D* ("dee star"), of an infrared detection devices' detectivity. (SL)

Described is an undergraduate laboratory experiment involving synthesis of chelidonic acid and its identification in plants. The experiment is offered as an ancillary topic for biology or chemistry classes. (SL)

Discussed is drag experiment for an intermediate level college mechanical physics course. Drag forces exerted on a falling object are examined. (Author/SL)

Describes two experimental apparatus which may be used to demonstrate the skin effect phenomenon. One apparatus shows the decrease of a magnetic field as it penetrates a thickness of metal; the other demonstrates the decrease with depth of current in a wire. (Author/MLH)

Describes a set of student projects, each involving about 240 hours of laboratory time, covering the following topics: wind power monitoring, wind generator design, solar power, and the heat pump. (MLH)

Describes an experiment that uses anodic stripping voltammetry as an alternative to atomic absorption for quantitating lead and cadmium leached from pottery samples. (MLH)

Describes an organic-biological experiment that illustrates an important chemical commercial process and the use of microorganisms as chemical reagents. (MLH)

Describes an experiment in which the iodonation of aniline reaction is shown to undergo catalysis in solution of sodium lauryl sulfate which forms micelles with negatively charged pseudo surfaces. (MLH)
