A continuous semiconducting thin film can be created from a large sheet of graphene, which does not have a bandgap at room temperature, using block copolymer lithography.
Dynamic changes in the light-driven proton pump, bacteriorhodopsin, which occur on stimulation with light, can be visualized using high-speed atomic force microscopy.
Ultrasharp scanning probe microscope tips made of diamond-like carbon that contains silicon and oxygen demonstrate very high levels of wear resistance.
Nanoscale filaments with a Magnéli structure are shown to be responsible for resistance switching in thin films of TiO2, and the properties of the filaments are directly observed during the switching process.
The quantum Hall effect has been measured in epitaxial graphene to an accuracy of a few parts per billion, potentially establishing a new quantum resistance standard.
Biological nanofactories selectively bind to bacteria and produce molecules that trigger a quorum sensing response and facilitate the communication with nearby bacteria, offering a way to generate new antimicrobial treatments.
Steps in the electrostatic potential at domain walls in a ferroelectric material give rise to a new kind of photovoltaic effect that produces voltages significantly higher than the bandgap of the material.
