This report describes the incorporation of digital learning elements in organic chemistry and biochemistry courses. The first example is the use of pen-based technology and a large-format PowerPoint slide to construct a map that integrates various metabolic pathways and control points. Students can use this map to visualize the integrated nature…

This final report of a feasibility study describes the research performed in assessing the requirements for a chemical signature file and search scheme for organic compound identification and information retrieval. The research performed to determined feasibility of identifying an unknown compound involved screening the compound against a file of…

Discussed are definition, history, approaches and methods, nature of the results, limitations, and future work in this new field. (DF)

Changes in the 1971 edition of the IUPAC book, Nomenclature of Organic Chemistry," from the previous editions (Sections A and B, 1966, and Section C, 1965) are listed with details of the changes. (Author)

This is the first of a two part series on Hermann Staudinger which describes the background of the discovery of chemical macromolecular structure. (DS)

Describes how the carbonylation of organoboranes in a suitable solvent can produce various alcohols, ketones, aldehydes and oxymethylation derivatives. The synthesis of alpha-alkylated ketone using alkylboranes is discussed. (RR)

This document presents the proceedings of the 19th Annual Research Forum held June 26, 2014, at Wake Forest University in Winston-Salem, North Carolina. Included are the following 17 action research papers: (1) Using Voices to Change Minds: Oral Performance and Poetry in the English Classroom (Erika Bunpermkoon), (2) Imagining Audiences: The Use…

This article presents a study of the techno-economical feasibility of manufacturing biofuel ethanol at small scale from agricultural sources in New Zealand. It investigates possible agricultural products and wastes as potential feedstock and looks at laboratory-scale fermentation trials to determine their ethanol yields. The ethanol requirement to…

A general result for the integrals of the Gaussian function over the harmonic oscillator wavefunctions is derived using generating functions. Using this result, an example problem of a harmonic oscillator with various Gaussian perturbations is explored in order to compare the results of precise numerical solution, the variational method, and…

The titration of HCl with NaOH has traditionally been used to introduce beginning chemistry students to the concepts of acid-base chemistry and stoichiometry. The demonstration described in this article utilizes this reaction as a means of providing students an opportunity to observe the dynamic motion associated with a swirling vortex and its…

Students in introductory chemistry classes often wonder about the relevance of chemistry to their daily lives. We have sought to increase their awareness by requiring each student in first- and second-semester general chemistry to make a two-minute presentation on a chemistry-related topic. This exercise gives students an opportunity to think…

A comparison of capillary rise and nucleation is presented. It is shown that both phenomena result from a balance between two competing energy factors: a volume energy and a surface energy. Such a comparison may help to introduce nucleation with a topic familiar to the students, capillary rise. (Contains 1 table and 3 figures.)

An experiment is described where students troubleshoot a published procedure for the analysis of ethanol. UV-vis spectroscopy is used to measure the change in absorbance upon reaction of dichromate with ethanol. The experiment requires the students to critically evaluate their experimental results to correct a fundamental flaw in the original…

The use of permanent magnet [to the thirteenth power]C NMR in large-section first-semester organic chemistry lab courses is limited by the availability of experiments that not only hinge on first-semester lecture topics, but which also produce at least 0.5 mL of neat liquid sample. This article reports a discovery-based experiment that meets both…
