The status of refrigeration fluids underwent a circle of changes in the 20th century. The invention of chlorofluorocarbons in the 1930s removed the health problem caused by leaks of toxic refrigerants, but by the 1970s CFCs became a serious threat to the enviornment. Throughout the century, JCE issues contained articles and short news bites about the fundamentals of refrigeration and the highs and lows of coolant fluids.
Our Secondary School editors work hard to distill all the JCE materials to produce a fraction of particular interest to high school teachers. We call it CLIC.
In recent years we have worked hard to better match our advertisers with our readers. When shopping for chemistry education materials, visit our advertisers' WWW sites first.
