Describes new experimental techniques, such as dye-laser photodetachment studies, which have recently provided accurate values for the electron affinity of numerous elements. Provides a periodic chart with available electron affinity data. (MLH)

Describes the chemical compounds responsible for the odor generated in the Kraft process of pulping wood chips; this subject can be used as a relevant topic in introductory chemistry, especially environmental chemistry. (MLH)

Divides addition reactions into molecular, stepwise, or termolecular, depending on whether the reaction is synchronous or multistep; and further into nucleophilic, electrophilic, or concerted, depending on how the electrons are transferred in the initiation step. (MLH)

Describes a laboratory activity in which polystyrene spheres in two preassembled motifs must be arranged to form a tetrahedral structure. (MLH)

Describes the construction of unit cells using clear plastic cubes which can be disassembled, and one inch cork balls of various colors, which can be cut in halves, quarters, or eighths, and glued on the inside face of the cube, thus simulating a unit cell. (MLH)

Addresses the problem of insufficient guidance for graduate students who are choosing their doctoral research area. Describes a required graduate course for all doctoral candidates in chemistry at SUNY Buffalo entitled, "Selection of Thesis Research." (MLH)

Describes a supplementary first-year chemistry course offered to selected students also enrolled in the regularly scheduled first-year chemistry course.

Describes a group of short courses, primarily for the high school science teacher, dealing with the chemistry of drugs, food, and water pollution; and a group of short courses, primarily for the full time college student, dealing with scientific instrumental methods. (MLH)

Describes a general chemistry autoinstructional system, without formal lectures, supplemented by tutorial assistance from paid undergraduate chemistry majors. Although examination results indicated that the Personalized Instruction System (PSI) students performed on the same level as the lecture section students, the PSI students felt they learned…

Describes an experiment, using a soap bubble raft, intended to provide insight into the orderly packing of spherical objects and the properties of metallic crystals. Also describes a solubility product experiment which uses barium hydroxide. (MLH)

Illustrates that the knowledge of crystal structure, particularly face centered cubic array, can be applied to an explanation of how a solid fuel nuclear reactor works. (MLH)

Provides procedures and comments for 15 short chemical experiments suitable for classroom demonstrations or public displays about chemistry. (MLH)

Describes a general chemistry level kinetics experiment requiring three 3-hour laboratory periods. Data analyses can be accomplished with graphical techniques or a non-linear least squares computer program. (MLH)
