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).

Creating An Online Form: Internet business

If you have recently established a website for your first internet business, adding a simple web form to your website, such as a feedback form, contact form, or other online form, can be a tough task. Most programming novices create their first website using pre-developed templates and have no advanced knowledge of HTML programming. As a result, creating a simple web form that can email the form responses to the webmaster can be a difficult and frustrating task. If you just posted a new website, but you do not have a web form uploaded and you need to quickly provide a way for your visitors to contact you, then you should simply post your email address on your Contact page. However, if you want to create a sophisticated online form to collect information from your visitors and respond to their questions, you need to know something about HT

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.

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 bring artificial photosynthesis a step nearer

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.

Directed self-assembly of polymers and nanotubes into air-suspended bridges

Polymers dissolved in volatile solvents can be directed to self-assemble into suspended nanofiber bridges through surface tension driven capillary thinning. This points towards a single step approach to forming suspended 3D structures in a considerably more simple way than by standard microfabrication processes. Fibers form when the polymer liquid is brushed by hand over a corrugated surface, as shown in the cartoon. To the right of the cartoon is a portion of an array and a closeup of polymer microfibers. The large mounds of polymer, compared to the fiber diameter, show how dramatically the fibers have thinned through the capillary forces. Carbon nanotubes can also be suspended, by dispersing them in the liquid polymer, forming fibers, and then thermally decomposing the polymer.

Carbon Nanotubes Target Tumor Cells, Deliver Anticancer Drugs

Platinum-based anticancer agents have a long history as proven therapeutic agents, but their toxicity and short lifetime in the body and the ability of tumors to develop resistance to these drugs limit the ultimate utility of these agents. In an attempt to overcome these limitations, a multi-institutional research team comprising members from Stanford University, the Massachusetts Institute of Technology (MIT) [profile], and the University of Duisburg-Essen in Germany is using targeted carbon nanotubes as delivery agents for an inactive form of platinum that cancer cells themselves convert into a toxic anticancer agent.
