Chromatographic instrumentation has been really influential in shaping the modern chemical practice, and yet it has been largely overlooked by history of science.Gas chromatography in the 1960s was considered the analytical technique closer to becoming dominant, and being the first automated chromatography set the standards that all the subsequent…

Education, science, and technology disciplines are closely and extensively connected in all formats and levels. The outbreak of COVID-19 has further squeezed this interconnection where the delivery of education in different scientific fields of studies at all education levels is almost impossible without the presence of technology. Today, there is…

Contains a short history of the development of industrial chemistry. (BB)

This article is designed to inform chemical educators not engaged in this technology as to the nature and methods used in the technology, the reasons for scientific and social concern, and the attempts made to assuage concerns involving recombinant DNA research. (author/BB)

Discusses various topics and issues related to the scientific enterprise in Cuba. Notes that Cuban science is emphasizing biotechnology and research on the island's chief crop (sugarcane), although hampered by limited personnel and lack of modern laboratory equipment. (JN)

Discusses role of laboratory techniques in scientific investigations. Describes Rutherford's development of scattering techniques and von Wassermann's development of test for syphilis. States that discovering an effect requires a brilliant scientist, however, making it a technique requires that it be made usable by ordinary people. Uses Moseley's…

Spill control methods have been developed to control, treat and monitor spills of hazardous materials during their manufacture, transport, and storage. Spills on both land and water, and methods of treatment and control in these environments were studied. A discussion of detection and monitoring equipment and protective clothing concludes this…
