Nanotube forests grown on silicon chips for future computers, electronics
Engineers have shown how to grow forests of tiny cylinders called carbon nanotubes onto the surfaces of computer chips to enhance the flow of heat at a critical point where the chips connect to cooling devices called heat sinks. view more (2007-10-02)
Friction force differences could offer a new means for sorting and assembling nanotubes
Nanotubes and nanowires are promising building blocks for future integrated nanoelectronic and photonic circuits, nanosensors, interconnects and electro-mechanical nanodevices. But some fundamental issues remain to be resolved - among them, how to position and manipulate the tiny tubes. view more (2009-09-16)
Study: Nanotech processing 'greener' than oil refining
Using a method for assessing the premiums that companies pay for insurance, a team of scientists and insurance experts have concluded that the manufacturing processes for five, near-market nanomaterials - including quantum dots, carbon nanotubes and buckyballs - present fewer risks to the environment than some common industrial processes like oil... view more...
