Literature on ion-selective electrodes (ISEs) is reviewed in seven sections: books, conferences, reviews; potentiometric membrane electrodes; glass and solid-state membrane electrodes; liquid and polymer membrane ISEs; coated wire electrodes, ion-selective field effect transistors, and microelectrodes; gas sensors and selective bioelectrode…

This review, designed to make analysts aware of uncertainties introduced into analytical measurements during sampling, is organized under these headings: general considerations; theory; standards; and applications related to mineralogy, soils, sediments, metallurgy, atmosphere, water, biology, agriculture and food, medical and clinical areas, oil…

This review on infrared spectrometry covering the period from late 1981 to late 1983, is divided into nine sections. Topic areas include: books; reviews; analytical applications; biochemical applications; environmental applications; polymer applications; infrared instrumentation; sampling techniques; and software and algorithms.

Suggests that a broad and balanced science education for all up to 16+ is a good thing, that it should be built from the bottom up, be differentiated to accomodate all abilities, and contain within it core streams in the general fields of biology, chemistry, and physics. (JN)

Describes the overall design, content, and use of Chemical Literature Exercises and Resources (CLEAR), a set of materials which introduces students to the chemical literature. Indicates that, overall, student evaluations of the CLEAR materials were very positive. (JN)

Describes an undergraduate experiment for the potentiometric determination of urea based on the physical entrapment of urease on the tip of an ammonia gas sensor. An advantage of this technique is the ease with which the ammonia electrode can be converted to a urea electrode. (JN)

Describes a variety of laboratory experiments including carbon dioxide reduction, animal respiration, atmospheric pressure determination, and others, that can be performed using discarded syringes. (GS)

Discusses the objectives and classroom management of IAC (Interdisciplinary Approaches to Chemistry) modules designed for individualized, self-paced instruction in secondary school chemistry. (MLH)

Describes an experimental method of isotope dilution analysis that determines radioactive compound volume rather than mass. Suitable for degree-level biology and chemistry students. (MLH)

Describes an experiment that utilizes an acidic ion-exchange-chromatography column to separate two cobalt complexes. (MLH)

Compares curriculum project adoption figures derived from examination entries with figures derived from questionnaires in an attempt to place the questionnaire returns in perspective and give an indication of the confidence which may be placed in them. (GS)

Presents an undergraduate experiment that uses ion-exchange techniques to recover the silver chloride precipitate from argentimetric determinations of chloride ions. (MLH)

Discusses the theory of radiometric force and the historical development of the radiometer. (MLH)

Discusses some current research on hemoproteins, describes the process of metal replacement in hemoproteins, and reviews the preparation of cobaltmyoglobin. (MLH)
