 | | Very Large 2D Superlattice Domain of Gold Nanoparticles | | The largest (19500x2037 pixels, 360,000 nanoparticles) 2D superlattice domain of 18 micrometer length and 8.8 nm lattice constant in a millimeter-scale monolayer film of hexagonal-close-packed gold nanoparticles. For details, check the J. Mater. Chem. 2011 paper (http://dx.doi.org/10.1039/C1JM11671A/) or the Eah group at RPI (http://www.rpi.edu/~eahs/).

 | | Monolayer-Protected Gold Nanoparticles: Ultra-Fast Synthesis & Ultra-Simple 2D Self-Assembly | | Monolayer films of gold nanoparticles can be fabricated simply by drying a toluene droplet without using any sophisticated instruments. Synthesis of dodecanethiolate-protected gold nanoparticles is fast, reproducible, and 1 nm size-tunable without any need for post-synthesis cleaning. For details, check the Eah group at RPI ("http://www.rpi.edu/~eahs/") or the Langmuir-2010 paper ("http://dx.doi.org/10.1021/la100591h"), one of the top 10 most downloaded papers over the last 12 months.

 | | Hindered rolling of carbon nanotubes | | When sliding on a nanotube along its axis and perpendicular to it, there is a large friction difference that origins in the soft lateral distortion of the tube. In the first part of the movie, an AFM tip is scanning transversely across a chiral nanotube. There is a shape distortion accompanied by an attempted lateral rolling and a large frictional force. In the second part, the tip is scanning longitudinally. There is a slight swaying of the tube due to the chirality, with a friction of about 1/2 of the transverse one. In the third part, as the outermost tube is nonchiral, no swaying of the tube is observed, corresponding to a much smaller friction. Simulations agree with the experimental results of the friction anisotropy, that can be used as a way to control the assembly of nanotubes on a surface for nanoelectronics, sensors and other applications. Our study can be found at 10.1038/nmat2529. | | | Added: 2 years ago, in category: Current Contest - What is Nano?

 | | How does salt dissolve in water? | | Here is the answer to how salt dissolves in water from computer simulations on some of the world's largest supercomputers. The large (yellow) chlorine ion at the corner of the crystal leaves first, as it leaves in becomes increasingly coordinated (bonded) to water molecules in the aqueous film above. | | | Added: 2 years ago, in category: Current Contest - What is Nano?
