Describes a double pendulum apparatus and its mode of operation to produce a great variety of figures similar to Lissajous figures. The author suggests that several advanced physics topics can be studied with the aid of this instrument. Bibliography. (LC)

How to move science-based labs online has been one of the main obstacles associated with the development of online science programs. In the spring of 2006 and again in 2007, we organized online workshops broadly based around the central theme of Moving the Lab Online. The objective of these workshops was to provide a forum for the exchange of…

This report presents the procedures, findings, and conclusions of a study designed to determine the effects of instrumentation of freshmen chemistry laboratory on achievement and interest in chemistry. Students in each of 80 matched pairs were randomly assigned to the two types of laboratory. One group used instrumented laboratory techniques and…

Voltammetry is used as a model for teaching chemical instrumentation to chemistry undergraduates at the National University of Singapore. Lists six criteria used to select a successful teaching model and shows how voltammetry satisfies each criterion. (JN)

The basic principles, current techniques, instrumentation, and possible chemical applications of nuclear magnetic resonance (NMR) imaging are discussed. (JN)

The Nebraska Instrument Sharing Consortium (NISC) is a group of small colleges that have banded together to provide modern instrumentation to their students at an affordable price. Consortium activities are described, including how the instruments are moved between campuses. (JN)

Discusses the nature of Fourier transform mass spectrometry and its unique combination of high mass resolution, high upper mass limit, and multichannel advantage. Examines its operation, capabilities and limitations, applications (ion storage, ion manipulation, ion chemistry), and future applications and developments. (JN)

Reviews applications of laser methods to analytical problems, selecting examples from multiphoton ionization and fluorescence analysis. Indicates that laser methodologies promise to improve dramatically the detection of trace substances embedded in "real" matrices, giving the analyst a most powerful means for determining the composition of…

Describes the nature and capabilities of methods used to characterize protein and peptide structure, indicating that they have undergone changes which have improved the speed, reliability, and applicability of the process. Also indicates that high-performance liquid chromatography and gel electrophoresis have made purifying proteins and peptides a…
