The Michelson interferometer is one of the best established tools for quantitative interferometric measurements. It has been, and is still successfully used, not only for scientific purposes, but it is also introduced in undergraduate courses for qualitative demonstrations as well as for quantitative determination of several properties such as…

When embedded within a continuum of mental health services including both prevention and treatment, school-based mental health identification programs can promote improved academic and mental health functioning among students. This article describes the scientific status of assessment instrumentation that may be used for early mental health…

A unifying modular approach to the description of modern instrumentation used in analytical measurements is described. Through the identification of five modules for analytical instrument, discussions pertaining to the different physical and chemical interactions can be better directed towards the similarities and differences in the actual methods.

Note is presented on the standard lab from a second year chemistry course. The lab "Determining which of the Seven FD&C Food-Approved Dyes are Used in Making Green Skittles", familiarizes students with the operation of the CHEM2000 UV-Vis spectrophorometer.

A study of the development of commercial electron spectroscopy of chemical analysis (ESCA) instrumentation over a span of three decades is presented. The field has also been extended significantly by use of synchrotron radiation as a bright X-ray source, which has opened new areas of research in solid-state physics, molecular biology, and many…

The author describes four capacities--interpretation, instrumentation, interaction, and inner direction--that are as important as traditional academic subjects in preparing young adults for college and career success. He suggests how high schools should address each of these capacities. For example, to develop students' capacity for inner…

This paper sits within the research on the affordances of new technologies in the mathematics classroom and focuses on a specific feature that is available in dynamic geometry environments, i.e. measuring tools, within the context of conjecturing and proving in open geometry problems. We develop a classification of different modalities of…

Investigates some of the psychometric characteristics of the results from visual-analogue scales used to measure mental imagery. Reports that the scores from visual-analogue scales are positively related to scores from longer pencil-and-paper measures of mental imagery. Implications and limitations for the use of visual-analogue scales to measure…

The difference between solution and surface properties such as pK(sub a) is illustrated enabling students to understand the differences between nanoscale and macroscopic systems. Details regarding the usage of electrochemical instrumentation, such as a potentiostat, and of the technique such as cyclic voltammetry are given.

Discusses the need to encourage increasing numbers of persons to enter analytical chemistry, educate them thoroughly in basic chemical science, and expose them to the most modern methods and instrumentation. Examines some problems and several university's efforts to overcome them. (MVL)

Discusses: (1) the design of the Fourier Transform-Infrared Spectroscopy (FT-IR) spectrometer; (2) the computation of the spectrum from the interferogram; and (3) the use of apodization. (Part II will discuss advantages of FT-IR over dispersive techniques and show applications of FT-IR to difficult spectroscopic measurements.) (JN)

Reviews literature on Raman spectroscopy from late 1981 to late 1983. Topic areas include: instrumentation and sampling; liquids and solutions; gases and matrix isolation; biological molecules; polymers; high-temperature and high-pressure studies; Raman microscopy; thin films and surfaces; resonance-enhanced and surface-enhanced spectroscopy; and…

Contained are condensed excerpts from the Lawrence Berkeley Laboratory Survey of Instrumentation for Environmental Monitoring. The survey describes instrumentation used to analyze air and water quality, radiation emissions, and biomedical impacts. (BB)

The development of an FI analyzer for chemiluminescence detection using a low-cost photoiodide is presented. The experiment clearly demonstrates in a single interdisciplinary project the way in which different aspects in chemical instrumentation fit together to produce a working analytical system.

Two studies were completed that focused on instrumentation and procedural issues associated with measurement of lingua-palatal contact pressure (LPCP) during speech. In the first experiment, physical features and response characteristics of 2 miniature pressure transducers (Entran EPI-BO and Precision Measurement 60S) were evaluated to identify a…
