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.
There is universal consensus among scientists and researchers that more work is needed on all of the new carbon nanomaterials that have been developed over the past years to adequately assess their toxicity and health risks. A recent review addresses the current status, trends and perspectives of this issue.
Fabrication of nanowires arrays with different patterns and separations is a major concern of the nanowire community. For this purpose, a catalyst template, which is usually a metal nanoparticle array, is needed to guide the nanowire growth.
The area of nanodielectrics is relatively unexplored but research shows that nanocapacitors could find important applications for instance in energy storage and ultrasensitive transducers in nanoelectronic circuits.
Researchers in Germany managed to integrate quantum dots (QD) into the walls of nano- and microtubes. This novel structure serves as a quantum light emitter as well as optical waveguide. This represents a major step toward the realization of flexible high quality factor optical resonators based on tubes.
Polymeric hollow nanospheres with high stability and controllable permeability have interesting potential applications associated with the controlled release of encapsulated active ingredients (e.g., drugs, vaccines, antibodies, hormones, pesticides, and fragrances) under well-defined conditions. Researchers in Singapore are now fabricating hollow nanostructures with different shapes using a single template.
