A simple method for filtering gold and silver out of water with carbon nanotubes
Silver single crystals were facilely synthesized on a large-scale with good reproducibility in water at room temperature in the presence of carboxyl-functionalized carbon nanotubes, without any additional reducing agent/electrochemical reducing, microwave, sonication or irradiations.
Controlled decoration of carbon nanotubes with nanoparticles
A newly developed electrostatic force directed assembly (ESFDA) technique is used to efficiently coat carbon nanotubes (CNTs) with nanoparticles. This new method advances the current technology by enabling rapid and in-situ coating of CNTs, multicomponent hybrid nanostructures, more control over the assembly process, and the possibility of tuning properties of the resulted hybrid structures.
Novel nanotube approach leads to significant performance improvement in composite materials
The extraordinary mechanical properties of carbon nanotubes (CNTs) have generated strong research interest in their possible use in reinforced composite materials. So far, different studies using carbon-nanotube reinforcements in polymer composites have reported only small improvements in the bulk mechanical properties compared with traditional fiber-reinforced composites. Through a novel approach, researchers have created a CNT-based composite material that exhibits significant improvements in fracture performance and structural damping.
Electromechanical switches based on telescoping carbon nanotubes
Researchers in China are proposing a nanoelectronic switch based on telescoping double-walled carbon nanotubes (TDWCNT). By varying the overlapping length at the junction, one could control the conducting states and change it between on (high conductance state) and off (low conductance state).
Attaching biomolecules to carbon nanotubes
Among the many potential biology-related applications proposed for carbon nanotubes (CNTs) are high-sensitivity biosensors and bio-fuel cells. In order to create the synergy between the biomolecules and CNTs required to realize these applications, biomolecules, such as proteins and DNAs, must be connected to the CNTs.
New techniques for fabricating carbon nanotube field emission displays
Researchers from the Zhengzhou Institute of Aeronautical Industry Management have developed a set of techniques to reduce the high cost of fabricating carbon nanotube field emission displays.
Converting carbon nanotubes into diamonds
Carbon nanotubes have been converted to diamonds before but a group of researchers in the PR China and the UK now managed to do this at a very low pressure of only 80 megapascal.
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.
