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).

True Properties of Carbon Nanotubes Measured

Carbon nanotubes' atomic structure should, in theory, give them mechanical and electrical properties far superior to most common materials. Unfortunately, theory and experiments have failed to converge on the true mechanical properties of carbon nanotubes. Northwestern University researchers recently made the first experimental measurements of the mechanical properties of carbon nanotubes that directly correspond to the theoretical predictions.

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.

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.

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: 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.

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.

Nanotechnology production materials come flowing out of volcanoes

(Nanowerk Spotlight) The demand for the raw materials of the nanotechnology revolution – nanoparticles, carbon nanotubes, fullerenes, quantum dots, etc – is rising explosively and large chemical companies keep expanding their production capacities. As production moves from a workshop model to an industrial production process, prices for these materials are coming down fast. Nowhere has this trend been more noticeable than with carbon nanotubes (CNTs), where prices have more or less collapsed from their astronomical levels: a kilogram of multi-walled carbon nanotubes (MWCNTs) sold for tens of thousands of dollars just a few years ago; by now, the price for some types of MWCNTs has fallen to only hundreds of dollars per kg.
