Describes a computer game used in an introductory experimental psychology class which simulates in a few months the activities of years of effort in a research laboratory. Ideas on developing new computer based simulation games are included. (Author/JJD)

Thermal features of and beneath the surface of a sample can be detected and imaged with a thermal-wave microscope. Various methodologies for the excitation and detection of thermal waves are discussed, and several applications, primarily in microelectronics, are presented. (Author)

Desorption ionization (DI) is used to obtain mass spectra of molecules whose vaporization by heating may lead to thermal degradation. Discusses DI techniques, characteristics of DI mass spectra, ion production, current applications of DI in mass spectroscopy, developments in DI, and prospects for future evolution of new DI techniques. (Author/JN)

The kinetic of the Jaffe reaction with picrate ion selective electrode (ISE) and a kinetic method for determining creatinine in urine is presented. The experiment could be used to familarize students with the application of ISE in kinetic studies and chemical analysis. (Author/JN)

Describes fluorescence experiments demonstrating that emitted light is at longer wavelengths than absorbed light and that fluorescence decays rapidly when the source of excitation is removed. Systems whose acidic and basic forms have different fluorescent characteristics are used to demonstrate fluorescence visible and invisible to the naked eye.…

Background information and procedures are provided for experiments in which the zinc and strontium content in bones (fossils and/or fresh mammalian samples) is analyzed to determine relative amounts of animal and vegetable foods consumed by an individual during its lifetime. (JN)

Reactions of phenolphthalein with sodium hydroxide and sulfuric are discussed. Also discusses the sulfonation of phenolphthalein, listing experimental results related to the sulfonation reaction. (JN)

Provides background information, procedures, and results of an undergraduate physical chemistry experiment on the polarization of absorption spectra of cyanine dyes in stretched polyvinyl alcohol films. The experiment gives a simple demonstration of the concept of linear dichromism and the validity of the TEM method used in the analyses. (JN)

Three experiments demonstrating the feasibility of encapsulating liquids within a starch matrix are described, including encapsulation of linseed oil using the zanthate method and of turpentine and butylate using the calcium adduct procedure. Encapsulated materials, including pesticides, are slowly released from the resulting matrix. Considers…

Background information, laboratory procedures, and discussion of results are provided for syntheses of cobalt (III) complexes, I-III, illustrating three possible bonding modes of glycine to a metal ion (the complex cations II and III being linkage/geometric isomers). Includes spectrophotometric and potentiometric methods to distinguish among the…

Laboratory procedures, background information, and discussion of experimental results are provided for the preparation of Thallium (I) Pentacyanocobaltate (II). The preparation of this pale green salt is carried out in an aqueous medium. (Author/JN)

Background information, laboratory procedures, and discussion of results are provided for the synthesis and chemiluminescence of adamantylideneadamantane-1,2-dioxetane (I). Results provided were obtained during a normal junior level organic laboratory course. All intermediates and products were identified using routine spectroscopic analysis.…

Background information, laboratory procedures, and discussion of results are provided for experiments designed to familiarize students with the biochemistry of nicotinamide coenzymes and the chemistry involved in their reactions. In addition, students are exposed to ultraviolet (UV)-spectroscopy as a tool for investigating reaction mechanisms in…

Describes use of laboratory kits for home-based experimental studies for external science students. Contents of kits and extra equipment the student would need are listed, selection of suitable experiments and arrangements for loan of kits are discussed, and performance of external students using kits is compared to that of internal students. (EAO)

Discusses current research on behavior in organizations as it relates to building group cohesiveness in a writing lab staff and describes the operation of the writing lab at the University of Central Arkansas. (AEA)
