Gas phase acidity data shown are offered to writers of elementary organic chemistry texts for replacement of the aqueous phase data that are universally used. Relative acidities in the gas phase are controlled virtually exclusively by enthalpic factors. Structural-energetic explanations of acidic trends can therefore be used. (SK)

Summarizes a survey on undergraduate research in chemistry from 1920-1976. Reviews the role and importance of factors such as faculty compensation and student ability on such research. Includes raw data for schools in the survey. (SK)

Describes a three-hour liquid chromatography experiment involving rapid separation of colored compounds in glass columns packed with a nonpolar absorbent. Includes apparatus design, sample preparation, experimental procedures, and advantages for this determination. (SK)

Examined and confirmed are differences in science and nonscience majors in the ways in which they obtain information about science and technology. Importance of these information sources was determined for each group: radio, television, newspaper, news magazine, scientific journal, family, friends, and faculty. (CS)

A series of well-defined steps is given for solving titrimetric problems, based on the mole concept. An example is given, including calculations from the first step to the last. (SA)

Provides a gas chromatography experiment that exercises the quantitative technique of standard addition to the analysis for a minor component, methyl salicylate, in a commercial product, "wintergreen rubbing alcohol." (CS)

Reviews the benefits and hazards of genetic engineering, or "recombinant-DNA" research. Recent federal safety rules issued by NIH which ease the strict prohibitions on recombinant-DNA research are explained. (CS)

Presents a description of the curricula in physics at 124 universities, colleges, and polytechnical institutes in England, Wales, and Northern Ireland. General information is provided on examination requirements for admission and procedures for making application to the schools. (SA)

Presents a description of the curricula in physics at 16 universities, colleges, and polytechnical institutes in Scotland. The entry requirements are summarized and procedures for making application are given. (SA)

Describes an autoremediation (self-remediation) system designed to allow students to diagnose their individual prerequisite deficiencies and then correct them. The system consists of a curriculum diagram, set of diagnostic tests, and a set of slide-tape self-instruction modules. Includes summary of evaluative efforts. (SK)

Offers rationale for and a description of a microprocessor-based control system project for mechanical engineering students. Includes reasons for selecting a Texas Instruments TM990/189 microprocessor system. (SK)

Reactions utilized to incorporate a metal-containing moiety into a polymer chain (addition, condensation, and coordination) are considered, emphasizing that these reactions also apply to smaller molecules. (JN)

Describes the historical development, performance characteristics (sample requirements, analysis time, ionization characteristics, speciation capabilities, and figures of merit), and applications of laser microprobe mass spectrometry. (JN)

An overhead projector, projection screen, and clear tungsten Filament light bulb operated through a dimmer or variac switch are used to demonstrate the fact that black appearance of sunspots is due only to contrast and that sunspots are bright. (SK)

The use of computers as laboratory instruments is viewed as overlooked. Numerous applications developed for a simple, single-board microcomputer by a group of Technical Education Resource Centers (TERC) are noted. The trend toward decreasing costs of lab interfacing is expected to continue into the future. (MP)
