Presents an experiment which includes fractional distillation with gas-liquid chromatography (GLC) and infrared analysis. Objectives are to introduce students to fractional distillation and analysis of each fraction by GLC, to induce them to decide if each fraction is sufficient for infrared analysis, and to identify unknowns.

Discusses issues related to comments made by Britain's Secretary of State for Education and Science that the government may soon take a more direct role in determining teaching/research programs at British universities. Includes comments on the dual support system and impact of potential changes in funding basic scientific research. (JN)

Provides background material which relates to the concept of activation energy, fundamental in the study of chemical kinetics. Compares the related concepts of the Arrhenius activation energy, the activation energy at absolute zero, the enthalpy of activation, and the threshold energy. (CS)

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)

Described is a nine-week undergraduate semester program (12 credit hours) conducted at the Bermuda Biological Station for Research which included three courses: introductory oceanography, sedimentology, and independent field study. Brief descriptions of sample student projects are included. (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…

Reports results of a survey of postsecondary students that examines the main difficulties encountered in using elementary algebra in the sciences. (CS)

Describes a computer program (FORTRAN and APPLESOFT) demonstrating the effect of copolymer composition as a function of conversion, providing theoretical background and examples of types of information gained from computer calculations. Suggests that the program enhances undergraduate students' understanding of basic copolymerization theory.…

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…

Provides background information procedures, and results for the photochemical synthesis and reactions of nitrosomethane dimer. The experiments described have shown a high degree of reliability with student use and are suggested to illustrate some problems of physical and organic photochemistry. (Author/JN)

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 an instructional strategy to convey the elements of trigonometry to introductory physics students. (SK)

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