For many college students, “pulling an all-nighter” is a familiar routine typically accomplished with copious amounts of caffeine. Often, the go-to option is a so-called “energy shot” drink that boasts a special blend of energy-boosting ingredients. New research by a behavioral neuroscience professor and her students at Centre College calls the popular drink—and the extra boost it claims to provide—into question. And their preliminary findings are creating quite a buzz.

Problem: Users in EM facilities with several current generation tools including FE SEM and dual beam FIB/SEM will, despite taking precautions to insert only clean specimens, sometimes get contamination introduced into their microscopes. This manifests itself as a dark rectangle on areas which have been exposed to the incident beam. How can this be prevented? Can it be removed from the previously exposed samples?
