Nanotechnology straws - capillary action at the nanoscale

(Nanowerk Spotlight) Various techniques are being developed to enhance the already impressive properties of carbon nanotubes (CNTs) further by combining them with other materials. We have covered plenty of examples in our Spotlights. For instance, encapsulating carbon nanofibers with CNTs transforms cheap commercial carbon nanotubes into highly efficient carbon for electrochemical energy storage applications (Converting conventional nanotubes into superior carbon for batteries). Another study demonstrated that the redox properties of iron and iron oxide particles are tunable via encapsulation within CNTs, suggesting that a host-guest interaction between the confined metal particles and CNTs, which is different from that on the outside of the nanotubes (see: Ethanol production inside carbon nanotubes).

Making carbon fullerenes with 100 percent efficiency

Carbon fullerenes—specifically C60, the spherical "bucky ball"—have received their fair share of attention, even in the shadow of the more buzz-worthy developments with carbon nanotubes and graphene. The bucky ball's spherical shape could allow it to contain molecules, while other chemical groups to can be attached to the surface, making biomedical applications a natural fit. Just like carbon nanotubes and graphene, however, bucky balls have proven difficult to synthesize reliably. Researchers have now discovered a method that produces the bucky ball configuration of carbon with nearly 100% conversion efficiency from precursor materials.

Carbon Nanotubes as a Single-Photon Source

Carbon nanotubes, as true multi-purpose materials, have potential applications in everything from electrical circuits and drug delivery to golf clubs and space elevators. Recently, physicists have investigated single-walled carbon nanotubes (CNTs) for one more use: as a single-photon source, where they could help make quantum communication networks extremely secure and efficient.

Measured properties of carbon nanotubes match theoretical predictions

(Nanowerk Spotlight) Carbon nanotubes (CNTs) have been hyped as the wunderkind material of the 21st century. And while researchers have developed numerous CNT applications, ranging from nanoelectronics to nanomedicine and military armor, the actual properties of CNTs fell way short of what the theory predicted. The Wikipedia page for CNTs gives an overview of the various values of CNTs' mechanical properties and shows the discrepancy between theoretical prediction and experimental values. For instance, quantum mechanics calculations predict that defect-free single-walled carbon nanotubes possess a tensile strength of well over 100 gigapascals (GPa) – which translates into the ability to endure weight of over 10,000 kg on a cable with a cross-section of 1 square millimeter.

Researchers Peer Into Water In Carbon Nanotubes

Researchers have identified a signature for water inside single-walled carbon nanotubes, helping them understand how water is structured and how it moves within these tiny channels. This is the first time researchers were able to get a snapshot of the water inside the carbon nanotubes.

Nanotechnology: Graphene takes on carbon nanotubes

Carbon nanotubes might have a cheaper, less controversial alternative in graphene, a single-layer flat sheet of carbon atoms that promotes strength and conductivity. Researchers at Northwestern University published their findings in Nature Nanotechnology, reporting that the breakthrough was made possible by isolating the proper kind of graphene sheet. According to a report from the Massachusetts Institute of Technology Review, having a few hydroxyl groups or oxygen atoms loose on the surface of graphene allows the material to link to polymers and disperse evenly. Researchers at Princeton, who coauthored the paper, were able to generate this form of graphene by expanding graphite oxide rapidly at high temperatures.

True properties of carbon nanotubes measured

For more than 15 years, carbon nanotubes (CNTs) have been the flagship material of nanotechnology. Researchers have conceived applications for nanotubes ranging from microelectronic devices to cancer therapy. Their atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials.

Carbon tubes without the 'nano'

There are carbon nanotubes, fullerenes and nano-foams, but now researchers have discovered yet another new type of carbon material: colossal carbon tubes. Thousands of times bigger than their nano counterparts, these tubes have exceptional mechanical and electrical properties and could find applications in microelectric devices and bullet-proof body armour.

Nanotubes Could Make For Bouncy Cellphones: I'm Talkin' to You Butterfingers

Ah nanotubes. Is there anything you can't almost possibly do? Well, now you can add bouncy cellphones to the list because a team of Clemson University researchers have developed a way to make beds of tiny, shock-absorbing coiled carbon nanotubes which could be used to cushion objects from damaging impacts. They hope that these coiled nanotubes could be used in everything from body armor to cellphones in the near future.

Nanotubes get sorted

When single-walled carbon nanotubes are made, a mixture of both metallic and semiconducting nanotubes is produced. This is a problem for those trying to make electronic devices from nanotubes, who need pure samples of either semiconducting or metallic tubes (depending upon the application), not both. Now, researchers in the US and South Korea have a developed a new and simple technique that not only efficiently separates the two types of nanotube but also allows them to be patterned onto a substrate as thin films. These films could be used to make electronic devices with desirable properties, and could even replace silicon as the material of choice for integrated circuits.

Nanotechnology basics: How does a carbon nanotube grow?

(Nanowerk Spotlight) One of the best ways to gain control over synthesis of nanoparticles is to watch it happen. Take carbon nanotubes (CNTs): Synthesis of CNTs is a field that is growing explosively – but there is a lot that nanotechnology researchers don't know about how nanotubes form and grow. While there are a number of in situ characterization methods for nanotube synthesis under development worldwide, each with different strengths and weaknesses, much of the information about the nanotube structure is indirect.
