Structure evolution at the gate-tunable suspended graphene–water interface
Using centimetre-sized substrate-free monolayer graphene suspended on aqueous electrolyte surface, the structural evolution versus gate voltage at the graphene–water interface is shown, demonstrating minimal influence of extrinsic factors.

Asymmetric response of interfacial water to applied electric fields
Experimental measurements of vibrational sum-frequency generation spectra indicate that the dielectric response of water near an electrode may be strongly asymmetric, with different responses to positive and negative electrode charge.

Clear signals from surfaces
Nuclear magnetic resonance is a versatile analytical technique, but acquiring well-resolved NMR spectra of chemical surfaces has been hard. The coming of age of a spectral enhancement method should change all that.
