A high-pressure phase of a material can be maintained even at ambient conditions by irradiating the material with heavy ions while it is under pressure.

Logic circuits can be enhanced by building a layer of memristors made of nanowires on existing chips.

Crystalline sheets of zeolite that are only one unit cell thick.

Strong control over the magnetic state of a solution-processed quantum dot doped with magnetic impurities is demonstrated.

A sensor based on single-walled carbon nanotubes can be used to monitor how certain cells take up materials.

By attaching a small molecule to the tip, an atomic force microscope can image the atoms within an adsorbed molecule.

Fullerene molecules make small holes when they adsorb onto a silver substrate.

Most scientists think of science as completely objective, but lab studies by social scientists — including several carried out in nanotechnology labs — suggest that it is more subjective than many scientists realize. Chris Toumey looks at the results of these studies.

Lack of progress on nanotoxicology has been highlighted by a tragic accident in China.

By analysing publication and citation data, it is possible to explore the relationships between nanoscience and nanotechnology and the rest of science and technology.

Silver nanoparticles can record temperatures of an event and be read out after the episode.

Water droplets can be self-propelled at high speed on nanopatterned wedge-shaped surfaces.

By imaging light emission from chains of silver atoms, a fundamental principle of quantum mechanism can be visualized.
