Presents an example of a greenhouse-effect experiment from the Climate Protection Institute. Analyzes the amount of carbon dioxide in ambient air, human exhalation, automobile exhaust, and nearly pure carbon dioxide by titrating with ammonia and bromthymol blue. (MVL)

Uses a method which involves weighing out an amount of the appropriate weak acid or base and dissolving it in distilled water close to the final volume. Solution is then titrated with strong acid or base to give the desired pH. Provides three examples. (MVL)

Estimates that about 30,000 universities, colleges, and high schools produce a total of 4000 metric tons of hazardous waste annually. Discusses the difficulties that academic institutions have in disposing of small amounts of waste. Lists college courses with the potentially hazardous wastes usually produced. (MVL)

Notes that bachelor's degrees under ACS approved programs decreased 6.8 percent while master's degrees decreased 3.3 percent. Ph.D. degrees showed an increase of only 1 percent. Provides a summary of degrees received between 1984-88. Includes a listing of chemistry and chemical engineering degrees awarded by ACS-approved schools for 1987-88. (MVL)

States that if photochemical reactions can be followed spectrophotometrically, reactivities can be estimated by evaluating data from only one curve. Studies such a system using computerized evaluation and simulation. Uses chlorocuprate(II) complexes in acetonitrile solutions for the model systems. (MVL)

Describes some support programs and materials that facilitate preparation of an effective and inexpensive classroom program on online searching of the chemical literature. Presents more than 20 databases by type of database and subject area. Discusses practice files and overall cost. (MVL)

Focuses on the CAS ONLINE database, the Registry File which consists of substance names, Registry numbers and characteristics, and actual structural representations. Presents several examples covering most typical problems a chemist faces daily. (Author/MVL)

Presents a practical and attractive alternative to the sand bath used in the microscale procedures developed by Mayo, Pike, and Butcher. Urges the organic chemistry teaching community to continue towards complete conversion to microscale techniques. Presents the use of aluminum devices in the microlaboratory. (MVL)

Describes the titration of a weak base with a strong acid and subsequent treatment of experimental data using commercially available software. Provides a BASIC program for determining first and second derivatives of data input. Lists 6 references. (YP)

Evaluates the attributes of a microcomputer software package as a supplement to chemistry instruction. Reports higher scores among the students in a control group. Discovers no significant interaction between treatment and development stage. Discusses several implications for further research. Provides the General Chemistry Test and error analysis…

Described is a heterogeneous catalysis course which has elements of materials processing embedded in the classical format of catalytic mechanisms and surface chemistry. A course outline and list of examples of recent review papers written by students are provided. (MVL)

Uses simple pulse NMR experiments to discuss Fourier transforms. Studies the generation of spin echoes used in the imaging procedure. Shows that pulse NMR experiments give signals that are additions of sinusoids of differing amplitudes, frequencies, and phases. (MVL)

Presents a device to illustrate the concepts of entropy of mixing and the contribution of one term in the Gibb's equation. Notes the device is relatively easy to construct and provides a visual demonstration on diffusion. (MVL)

Proposes that higher education insist more on the education of its chemists and less on strictly instrument training. Lists several instances where education may have been more useful than the strict training military officers received. Discusses the role of chemists in society. (MVL)

Covers four areas that relate to the 1989 employment outlook for chemistry: the importance of the use of computers in undergraduate chemistry education; current demand for chemical professionals; current salaries; and availability of career planning. (MVL)
