A computer chip using nanotube circuitry can run much faster than a regular silicon chip, for a fraction of the cost, but no one has been able to effectively string together two nanotube transistors, let alone the thousands needed for a chip. Until now: researchers at Stanford University have built the first nanotube circuits, by stamping multiple layers of nanotubes on top of one another.
The stamping method involves using metal electrodes to guide the nanotubes into place. In effect... Read Full Story
Microscopic carbon nanotubes a hundred thousand times thinner than a human hair may have the potential to transport electricity faster and over greater distances with minimal loss of energy, according to new research that will be published Friday, in the October 2nd edition of Science magazine. The research was led by Honda Research Institute USA, Inc., in conjunction with researchers at Purdue University and the University of Louisville. The findings open new possibilities for...

Researchers have simplified the process of creating flexible sheets of carbon nanotubes, which can serve as components of batteries and supercapacitors.
Graphene and carbon nanotubes have a combination of excellent electrical properties and light weight that may eventually revolutionize electronics and energy storage technologies. But for now, most of their applications remain stuck in research labs, as producing them in bulk and then incorporating them into a device have... Read Full Story
Single-walled nanotubes -- cylinders of carbon about a nanometer in diameter -- have been highly touted for potential applications such as ultrastrong fibers, electrical wires in molecular devices, or hydrogen storage components for fuel cells. Thanks to a new development by researchers at the National Institute of Standards and Technology (NIST) and five partners, you can add one more application to the list: detection and destruction of an aggressive form of breast cancer. HER2 is one of a... Read Full Story
It seems like we're constantly hearing about promising battery technologies that could ultimately lead to longer battery life, more power, and smaller units, but as of yet, that big breakthrough hasn't occurred. Maybe nanotechnology, which is the current hot topic in the battery innovations field, will prove to be different .
Right at this moment, a ton of research is being put into carbon nanotubes (CNTs) for a bunch of uses, including electronics and batteries. Researchers are drawn to... Read Full Story

University of California San Diego researchers have developed a method to enhance the capacitance (up to three times) of carbon nanotube (CNT) electrode-based electrochemical capacitors by controllably incorporating extrinsic defects into the CNTs.
“While batteries have large storage capacity, they take a long time to charge; while electrostatic capacitors can charge quickly but typically have limited capacity. However, supercapacitors/electrochemical capacitors incorporate the... Read Full Story
Green Ocean Coatings from Advanced Marine Coatings are an environmentally friendly way to make transport by sea more cost-efficient Leverkusen - The Norwegian company Advanced Marine Coatings based in Gamle Fredrikstad specializes in the development of environmentally compatible, heavy-duty anti-corrosion coatings for sea-going vessels. The 'Green Ocean Coating Heavy Duty' coatings are formulated with Baytubes® carbon nanotubes (CNT) from Bayer MaterialScience, which gives them very high... Read Full Story
Researchers at the University of Southern California have demonstrated large, functional arrays of transistors made using simple methods from batches of carbon nanotubes that are relatively impure. For the first time someone has shown solution-deposited, purified semiconducting tubes for high-quality transistors,” says John Rogers, professor of materials science and engineering at the University of Illinois at Urbana-Champaign. “The accomplishment is in the integration of several...

With all of the technology that is being continuously introduced and used, it would only seem logical in our quest for a green world to apply some of the renewable energy efforts to this spectrum. That is exactly what some scientists are looking into with theirresearch on how nanotechnology can be used with lithium batteries. According to Science News, a report that will be published in International Journal of Nanomanufacturing asserts that "carbon nanotubes can prevent such batteries from... Read Full Story
