Describes the procedures for construction of a nitrate coated-wire ion selective electrode and suggests experiments for evaluation of electrode response and illustration of typical analytical applications of ion selective electrodes. (CS)

Presents an undergraduate experiment demonstrating sampling error. Selected as the sampling system is a mixture of potassium hydrogen phthalate and sucrose; using a self-zeroing, automatically refillable buret to minimize titration time of multiple samples and employing a dilute back-titrant to obtain high end-point precision. (CS)

Presents an undergraduate quantitative analysis experiment, describing an atomic absorption quantitation scheme that is fast, sensitive and comparatively simple relative to other titration experiments. (CS)

Suggests nonfiction science books and novels for an elementary unit on science fiction. (SJL)

Relates a number of fundamental misconceptions and errors relating to the concepts of the crystal lattice and crystal symmetry. (CS)

Describes how a simplified version of order-disorder theory can be presented in an undergraduate course on physical or solid state chemistry. This version is also shown to be useful in dealing with a variety of physical phenomena. (CS)

Discusses optical fiber materials necessary for high performance telecommunications applications, fiber strength and coating, loss in optical fibers, and radiation damage in optical fibers. (CS)

Reviews the structure, preparation, and physical properties of a series of compounds characterized by structures formed from sublattices which have incommensurate repeat distances in one or two directions. (Author/CS)

Describes some contemporary concepts unique to the structure of advanced solids, i.e., their crystal distortions, domain structures, modulated structures, ferrimagnetism, and composition dependence. (Author/CS)

Rederives the relativistic transformations of light intensity from compact sources (stars) to show where and how the transformation of a solid angle contributes. Discusses astrophysical and other applications of the transformations. (Author/CS)

Presents a novel graphic representation for complex musical spectra, based on component intervals rather than component tones. Provides examples of this kind of plot in representing complex intervals and chords, discussing perceptual data; and carrying out various types of consonance analysis. (Author/CS)
