Graphene Pocket and Bubble Formation

Caption

(A) Graphene pocket protects the sample contained in the liquid. (B) Photo of the graphene pocket. (C) As a result of the incident electron beam, an air bubble fills most of the pocket after a short period of time. (D) Bubble forming time, depending on the type of solution filling the pocket. The longest bubble-free time is obtained when the pocket is filled with a) heavy water (D2O), followed by water (H2O) with b) 50% glycerol, c) 100 mM NaCl, d) 10 mM n-propyl gallate, e) 3% glycerol, and f) water only.
