This month's cover depicts the history of ion selective electrodes
up to the 1980's, as reported at the seventh James L. Waters Symposium,
held at Pittcon in March 1996. Included are a variety of electrode
designs, the cover page of Arnold Beckman's patent for a vacuum-type
pH meter, and a time line showing developments and the people who
made them. In our special section on the Waters Symposium, Frant,
in Where Did Ion Selective Electrodes Come From?,
describes development and comercialization of ion selective electrodes.
Ruzicna, in The Seventies - Golden Age for Ion
Selective Electrodes, reports on the interactions among industrial
and academic chemists during that time. Light discussesIndustrial
Use and Applications of Ion Selective Electrodes, and Young's
Evolution of Blood Chemistry Analyzers Based
on Ion Selective Electrodes shows how ion selective electrode
developments led to improvements in blood chemistry analyzers.
The "Chemistry Teacher Connection" (CTC) is especially for high school chemistry teachers. For only $40/year, it offers an online-only subscription to CLIC along with membership in the Division of Chemical Education, normally $65/year. CTC subscribers receive access to all articles and supplements from 1996 through the current issue.
Through special arrangement with the ACS, JCE High School CLIC is now able to provide subscribers with online access to Chemical & Engineering News articles that have been selected specifically for secondary science instructors and their students.
Occasionally, collections of JCE back issues become available for donation to individual teachers, schools, or libraries. JCE matches collections with interested recipients. Recipients pay shipping costs or pick up the collection.
