Manufacture, properties, uses, and economic aspects of inorganic chemicals are discussed in an industrial chemistry course. Provided and discussed is a flowchart used in the course. The flowchart is a logical method of presenting the important features of inorganic chemicals and a summarizing their method of manufacture. (JN)

Describes an experiment designed to teach temperature programed gas chromatography (TPGC) techniques and importance of derivatizing many classes of substrated to be separated. Includes equipment needed, procedures for making trimethylsilyl derivatives, applications, sample calculations, and typical results. Procedure required one, three-hour…

Describes a laboratory designed to give students practical experiences with experimental phenomena discussed in lectures, focusing on laboratory organization and typical experiment. In addition to a list of experiments, three exercises are discussed: fluorescence/laser, ferromagnetic domains, and thermal population (which uses PET computer…

Discusses five recent advances in sedimentary tectonics, noting how they are incorporated into college curricula. Advances discussed include basin type, tectonic setting, facies analysis (in conjunction with basin type/setting), stratigraphic analysis of reflection seismic data, and quantitative analysis of subsidence histories of sedimentary…

Discusses the physics of liquid crystal displays (LCD) which is based on polarizing properties of crystals controlled by electric command. Production of alphanumerics, display control, and input are considered. (JM)

Describes the construction of a small (portable), inexpensive, and easy to build Foucault pendulum. Includes photographs of the apparatus, a schematic of the electrical circuit used, and discussion of the amount of accuracy to be expected during classroom investigation. (JM)

Discusses mechanisms and functional intent of visual communication signals in iguanid/agamid lizards. Demonstrated that lizards communicate with each other by using pushups and head nods and that each species does this in its own way, conveying different types of information. (JN)

Focusing on research is suggested as an approach for teaching organic chemistry for nonmajors. Topics of saturated hydrocarbons and unsaturated hydrocarbons are used as examples to illustrate the approach. (SK)

Outlines content and use of slide audiotape pre-lab lectures at California State College (Stanislaus). Includes advantages of using the materials and data, indicating their success as teaching aids. (Author/SK)

Presents an experimental comparison of the efficacy of two neutron sources under conditions commonly used in laboratory experiments for demonstrating neutron activation of liquid samples. (Author)

Lists physics courses at universities, colleges of education and technology, and polytechnics in England, Wales, and Northern Ireland. Includes honors degree courses, course structure, special entry requirements (if any), special notes, and name of contact person. (SK)

Electrochemical studies can give insights into the chemical aspects of enzymatic and in vivo redox reactions of naturally occurring organic compounds. This is illustrated by studies of the electrochemical oxidation of the purinem uric acid. The discussion is limited to information at pH 7 or greater. (JN)

The current organic synthesis program at Harvard University is called the Logic and Heuristics Applied to Synthetic Analysis (LHASA). Discusses this program in detail, focusing on retrosynthetic analysis approach, LHASA hardware, graphical input/perception, strategy control, transform evaluation, and LHASA enhancement. (JN)

Describes a procedure which identifies an experiment as unreasonably hazardous or indicates precautions to be taken rendering the experiment acceptable for assignment to undergraduate students. The procedure follows in parallel form the procedure used to prepare chemical labels. (Author/JN)

Reviews mathematical techniques for solving systems of homogeneous linear equations and demonstrates that the algebraic method of balancing chemical equations is a matter of solving a system of homogeneous linear equations. FORTRAN programs using this matrix method to chemical equation balancing are available from the author. (JN)
