Describes a course in chemometrics offered at Tufts University which is designed to provide college chemistry majors with an understanding of potential roles which computers might play in chemical research. (CS)

Two laboratory procedures in experimental chemotaxonomy are outlined for determining the presence of betalains in genera representing different plant families. A list of materials and equipment needed is provided. (DC)

Lists colleges and universities having the most chemistry graduates in 1979-1980, including the totals for B.S. graduates, certified B.S. graduates, M.S. graduates, and Ph.D. graduates. (CS)

Reviews information on solar radiation as an energy source. Discusses these topics: the key photovoltaic material; the bank theory of solids; conductors, semiconductors, and insulators; impurity semiconductors; solid-state photovoltaic cell operation; limitations on solar cell efficiency; silicon solar cells; cadmium sulfide/copper (I) sulfide…

Describes a simple, relatively inexpensive, and easily implemented approach for introducing visually handicapped students to chemical instrumentation via experiments on operational amplifiers as examples of some of the electronic building blocks of chemical instrumentation. The approach is applicable to other chemical instruments having electrical…

Describes a general chemistry course which encourages students to investigate the applications of chemical concepts to everyday situations. Commercially available products are analyzed and the accuracy of manufacturers' claims are evaluated. For example, students compare different aspirin brands, calculating percentage of active ingredients and…

Suggests reasons why courses in industrial chemistry are desirable, briefly outlines the course taught at Colby College (Maine) for the past four years, and points out some lessons learned from this experience. (Author/SK)

Describes the discovery, physical properties, and future applications of liquid crystals. (SK)

Reports proceedings of the First Annual Workshop at the Interface of High School and College Chemistry, sponsored by the Cincinnati Section of the American Chemical Society. The conference brought together secondary and college chemistry teachers in an effort to establish communication and enhance interaction between the two groups. (Author/CS)

Thermochemical cycles are used to decide which hypothetical compounds might exist and, if not, what is the factor that condemns them to non-existence. Hypothetical compounds of rare gases provide examples of the approach with added historical interest that thermochemical considerations led to prediction and demonstration that XePtF-6 was stable.…

Provides syllabus for courses in introductory polymer chemistry (including major topics and recommended time allotments) and currently available textbooks and audio courses which may be used with the syllabus. Syllabus topics are congruent with those used in American Chemical Society (ACS) standardized examination in polymer chemistry. (Author/JN)

Describes interactive, computer-graphics program emulating behavior of high resolution, ultraviolet-visible analog recording spectrophotometer. Graphics terminal behaves as recording absorption spectrophotometer. Objective of the emulation is study of optimization of the instrument to yield accurate absorption spectra, including…

Describes a semi-automatic viscometer which incorporates a microprocessor system and uses optoelectronics to detect flow of liquid through the capillary, flow time being displayed on a timer with accuracy of 0.01 second. The system could be made fully automatic with an additional microprocessor circuit and inclusion of a pump. (Author/JN)

Describes modification of a gas viscometer to produce a low cost instrument with high precision and safe design. Three tungsten electrodes are mounted in the viscometer using graded glass seals and a ball trap is inserted between mercury reservoir and all external stopcocks. Also describes modifications in experimental procedures. (Author/JN)

Describes an experiment in which parameters from an "ab-initio" potential are used to calculate vibrational-rotational energy levels and construct a "stick spectrum" for the overtone emission of the hydroxyl radical. Provides background information on ab-initio spectrum, experimental procedures, and analysis of data. (Author/JN)
