Describes the life of Niels Bjerrum, a Danish physical chemist, best known as the originator of the concept that strong electrolytes are almost completely dissociated into ions in solution. (Author/JN)

Provides a brief review of the latest developments in nuclear chemistry. Nuclear research today is directed toward increased activity in radiopharmaceuticals and formation of new isotopes by high-energy, heavy-ion collisions. (Author/BB)

Describes CIRRUS (the Chemistry Internet Resource for Research by Undergraduate Students), an Internet-based resource in support of the undergraduate chemical research enterprise. Supports communication and information-sharing by providing a companion electronic mail server. Presents examples of services provided by CIRRUS. (JRH)

Discusses the use of the mixture of a carboxylic acid and sodium borohydride as a reagent. The chemical mechanism of the mixture is described using structural formulas. Lists 15 references. (YP)

Outlines the chemistry of the rapid synthesis of relatively large DNA fragments (100-200 monomers each) with yields exceeding 99 percent per coupling. DNA synthesis methodologies are outlined and a polymer-supported synthesis of DNA using deoxynucleoside phosphoramidites is described with structural formulas. (YP)

Describes current and cutting-edge research on proteins that may spark the interest of biology students. Contains 27 references. (WRM)

Discusses the most famous hoax in the history of science involving fossils including fragments of human or simian skulls and jaws and teeth found in gravel pits. Describes a laboratory experiment that exposes students to the problems of scientific misconduct. (CCM)

Toni Austin Watt, the winner of the 2004 James Bryant Conant Award in High School Chemistry Teaching says that she was always an average student and had to invest more time in improving her skills and getting experiences, thus she is exhilarated that her efforts have received such acclaim and is honored that people thought her efforts were…

Marion D. Francis and Rosemary L. Centner tell the story of a special group of compounds, developments at their home company, Procter and Gamble, and contributions by researchers in Europe and the U.S., in "The Development of Diphosphonates as Significant Health Care Products."

A study involves multiple chemistry and physics concepts applied to a state of matter that has biological relevance. An experiment involving the synthesis and physical properties of liquid crystals illustrates the interdisciplinary nature of liquid crystal research and the practical devices derived from such research.

Discusses legislation and programs aimed at preventing occupational cancer. Includes the results of recent research in the identification of occupational carcinogens. (MLH)
