The interesting transport properties of SWNT nanorings

As a novel superstructure, single-walled carbon nanorings exhibit interesting transport properties, such as Aharonov-Bohm effects, magnetotransport or establishment of persistent currents. Researchers in China have developed a new technique to produce large quantities of small-diameter single-walled carbon nanotube (SWNT) nanorings.

Fabricating palladium nanostructures in a simple and inexpensive way

Researchers in Canada used the electroless deposition process for self-assembling Palladium nanostructures, such as wires, from nanoparticles on a rough stainless steel substrate. This discovery holds a lot of potential for various engineering applications because the deposition process and the preparation of the substrate are simple and inexpensive.

Bonding of carbon nanotubes to metal electrodes through ultrasonic nanowelding

Building reliable interconnections between carbon nanotubes (CNTs) and external electrical and mechanical systems is an essential prerequisite to exploring the potential of CNTs in various domains. The formation of a stable and low-resistance ohmic contact between CNTs and electrodes contributes to speeding up the development of applications with CNTs in nanoelectronic devices with small size, fast speed and low power dissipation.
