Describes an experiment that shows that fluorescence emission intensities are significantly modified by absorption processes and that these effects can be eliminated by positioning the sample cell such that the interrogation region corresponds to the corner of the cell. (MLH)

Demonstrates how to use the area of proton magnetic resonance peaks to distinguish protons in water molecules close to a metal cation from protons in the bulk of the water. (MLH)

Discusses a chemical engineering course which includes laboratory experiments on polymerization, polymer fabrication, and polymer properties. (MLH)

Discusses the dipositive oxidation state of silicon and describes laboratory experiments concerning the synthesis and reactions of silicon difluoride. (MLH)

Describes an experiment in which the student is presented with the problem of selecting a suitable indicator for the determination of the hydroxide in basic copper chromate. (MLH)

Summarizes the early discussion results in the development of a physics project in higher education. Indicates that the first-year experience concentrates on the following aspects: laboratory work, tutorial programs, and individualized instruction. (CC)

Describes some laboratory projects to enable high school students to learn about bromelin, a protein-digesting enzyme. (PS)
