Studying localized corrosion using liquid cell transmission electron microscopy

12 November, 2014 - 19:17

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC06443G, CommunicationSee Wee Chee, Sarah H. Pratt, Khalid Hattar, David Duquette, Frances M. Ross, Robert Hull
Localized corrosion of Cu and Al thin films exposed to aqueous NaCl solutions was studied using liquid cell TEM. We demonstrate that potentiostatic control can be used to initiate pitting and that local compositional changes, due to FIB implantation of Au+ ions, can modify the corrosion susceptibility of Al films.

Co-solvent exfoliation and suspension of hexagonal boron nitride

12 November, 2014 - 19:17

Chem. Commun., 2014, Advance Article
DOI: 10.1039/C4CC07324J, CommunicationK. L. Marsh, M. Souliman, R. B. Kaner
A simple method is presented for exfoliating and suspending hexagonal boron nitride using a co-solvent approach. A 60 w/w% concentration of tert-butanol in water is very effective at exfoliating boron nitride especially when compared to the individual components alone as indicated by UV-vis and transmission electron microscopy. Molecular weight and surface tension are found to play inverse roles in the exfoliation.
