CEP: September 2014

Some materials are more vulnerable to supply disruptions than others. This month's cover feature on critical materials introduces methods to identify at-risk critical materials, and outlines general strategies to address challenges related to these materials. Other article topics include: solid-fluid equilibrium modeling; DOE's Superior Energy Performance program; and identifying energy-saving process improvements.

Elements of Fun

Whenever I come across an interesting article or tidbit of information in the general media that I think might make a good topic for an editorial, I file it away. Then, each month when it’s time to write my editorial, I browse through those (paper and electronic) files to find anything that relates to what’s in the issue or what’s happening at AIChE.
A few years ago, I came across Discover magazine’s “20 Things You Didn’t Know About … The Periodic Table,” and I knew it was a keeper. Surely, I thought, at some point I’ll be able to relate this to an article.
