Let your friends know you're working late in the lab, tell everyone your paper was accepted by JACS, and send your PI a research update with your very own chemistry emoji set! Choose from a developing set of chemistry themed emoji featuring traditional smiley faces decked out in goggles (safety first!), glassware, the periodic table, element tiles that spell out some of your favorite Internet acronyms, and two very important molecules. Use the ACS Chemoji app to share the experience of chemistry with your friends by text or use it on Facebook and Twitter. Tell us your Chemoji story with the #ACSchemoji hashtag.
