Cover: Exploring Magnetic Properties

In Microscale Extraction of Liquid Oxygen from a Cryogenic Mixture Formed through Condensation of Ambient Air, Jeffrey Statler describes a simple and inexpensive demonstration, in which small amounts of liquid oxygen can be safely collected and observed through condensation using a small neodymium magnet. Several techniques are suggested that allow for efficient handling and display of the magnet used for the extraction. The cover shows a small neodymium magnet suspended from the end of a bent paper clip, extracting liquid oxygen from a cryogenic mixture by virtue of its paramagnetism. The cryogenic mixture was collected in 25 minutes via condensation from air into a previously empty test tube as it was partially submersed in liquid nitrogen.

From the Archives: Chemistry Outreach

In the article, Characterizing the Landscape: Collegiate Organizations’ Chemistry Outreach Practices (available to non-subscribers as part of ACS’s Editors’ Choice program), Justin M. Pratt and Ellen J. Yezierski examine practitioners’ expected outcomes of outreach events, the types of activities and chemistry content widely practiced, and how outreach practitioners evaluate the success of events. The top three most frequently mentioned activities have been discussed extensively in past issues of JCE:
