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.

DOI: 10.1039/C4CC06916A, CommunicationKhoi Tan Nguyen
Electronically enhanced chiral SFG spectroscopy was employed to study the lipid bound cyt c in situ. It was directly observed that upon interacting with anionic phospholipids, the amino acid residues around the heme adopted the [small beta]-sheet conformation. In addition, the orientation of this newly formed [small beta]-sheet structure was found to be sensitive to the bulk pH.
