the team fabricated single crystal nanostructures made with III-V materials, including alloys of indium, gallium and arsenide.

and to lithographically define oxide templates and fill them via epitaxy, making nanowires, cross junctions,

nanostructures containing constrictions and 3d stacked nanowires. According to Schmid, more work is required before the same level of control can be exerted over III-V materials as currently exists for silicon,

#Researchers produce'nanoribbons'with mortar and pestle A newly discovered solid-state chemical reaction could help advance the production of nano-strucutures,

Now, researchers at Rice university in the US have found a new way of producing the material by grinding modified nanotubes with a mortar and pestle.

According to materials scientist Pulickel Ajayan this breakthrough reported in the current issue of Nature Communications-has been achieved by mixing two types of chemically modified nanotubes which,

react and unzip into nanoribbons. The team claims that the new process could lead to significant advances in nanomaterials development. f we can use nanotubes as templates,

functionalise them and get reactions under the right conditions, what kinds of things can we make with a large number of possible nanostructures and chemical functional groups?

said Ajayan. In their tests, the researchers prepared two batches of multi-walled carbon nanotubes, one with carboxyl groups and the other with hydroxyl groups attached.

When ground together for up to 20 minutes with a mortar and pestle, the chemical additives reacted with each other,

triggering the nanotubes to unzip into nanoribbons, with water as a byproduct. The experiments were duplicated by participating labs at Rice, at the Indian Institute of technology and at the Lebanese American University in Beirut.

so the energy enough to break up the nanotubes into ribbons, but the details of the dynamics are difficult to monitor,

Beirut. here no way we can grind two nanotubes in a microscope and watch it happen.

which densely populated, lumpy nanostructures were formed. The optical and wetting properties of the surfaces of the three metals were altered by these nanostructures.

The nanostructures created by the lasers are intrinsic to the metal surface. According to the researchers, properties they provide to the metal will not deteriorate.

The super-hydrophobic properties of the laser-patterned metals are similar to the famous nonstick coating.

They used extremely thin nanowires that were made of indium arsenide to fabricate the quantum dots. The placed the qubits 6 mm apart in a cavity that was made from niobium at a temperature near absolute zero(-459 degrees Fahrenheit.
