Carbon nanotubes (CNTs) are allotropes of carbon with a cylindrical nanostructure. Nanotubes have been constructed with length-to-diameter ratio of up to 132,000,000:1, significantly larger than for any other material. These cylindrical carbon molecules have unusual properties, which are valuable for nanotechnology, electronics, optics and other fields of materials science and technology. In particular, owing to their extraordinary thermal conductivity and mechanical and electrical properties, carbon nanotubes find applications as additives to various structural materials. For instance, nanotubes form a tiny portion of the material(s) in some (primarily carbon fiber) baseball bats, golf clubs, or car parts.
A group of researchers at MIT have devised a new method for infiltrating cells with large molecules such as nanoparticles or proteins that is a lot more non-intrusive and doesn’t damage the cell. Imaging target cells or growing more stable stem cells might thus be possible with this method. Every cell has a membrane, which [...]
Scientists at University of Texas Dallas have made artificial muscles capable of supporting 100,000 times their own weight and generate 85 times more mechanical power than natural muscle of the same size. Applications for this kind of technology are quite numerous, ranging from extremely strong and intelligent textiles to high-temperature applications since the fabric has [...]
Scientists at Stanford University have successfully devised the world’s first solar cell made entirely out of carbon. This alternative to typical silicon solar panels is not only a lot cheaper to produce, but also a lot less simpler to use. Such carbon cells can be coated on any surface and turn it into a solar [...]
Researchers at MIT have developed a novel technique of creating cheap and reliable sensors for toxic gases by simply etching carbon nanotubes with a mechanical pen on a special paper, fitted with electrodes. The method allows for easy to make, cheap and reliable sensors that detect noxious gases in the environment, without the hassle that [...]
While on the macro-scale conventional scales make us of gravity to measure mass, on the microscale there are a myriad of factors that interfere with measurements. Scientists at Universitat Autònoma de Barcelona have successfully created a scale made out of a single carbon nanotube which can accurately measure the smallest unit of mass, a yoctogram (one [...]
A team of researchers comprised of scientists at the NanoScience Center of the University of Jyväskylä, Finland, and at Harvard University, US, have shown through computer simulations a novel technique for generation nanomaterials. The whole process revolves around the extremely simple idea of twisting narrow graphene nanoribbons until they become rolled up into carbon nanotubes, [...]
This is the kind of engineering feat that sounds so preposterous, so crazy, so … foolish, that it might actually work. A Japanese construction company plans to build an elevator that can lift tourists in space, up to a quarter the distance between Earth and the moon. While entrepreneurs like Richard Branson or Paul Allen [...]
Butterflies are one of the most enchanting beings in the animal kingdom, a symbol of grace and beauty encountered in every art form. From a crawling larva to a majestic winged creature, it’s difficult not to take notice of the similarities between the butterfly’s metamorphosis process and the ups and downs life serves before one [...]
Recently, a team of scientists have created a new metallic material which they claim to be the lightest in all the world, not even coming close to styrofoam or aerogels, and even making carbon nanotubes seem heavy. This lightest material has an estimated density of just of 0.9 milligrams per cubic centimeter (mg/cc), compared with [...]
In the new mobile information age where smartphones have become an ever common part of our lives, there seems to be a dominant trend which tends to incorporate interactive touch screen capabilities to more and more consumer electronics. It’s pretty clear that our electronics are getting smarter day by day – I, for one, am [...]
This is the best video I’ve seen in quite a while ! Don’t let the fancy title fool you, the video explains what’s happening so it’s really easy to understand what’s happening.
Carbon nanotubes (CNTs) are allotropes of carbon. Their strength and flexibility makes them useful in controlling other nanoscale structures, which suggests they will have an important role in nanotechnology engineering. They are also used in concrete where they increase the tensile strength, and halt crack propagation in elevators, bridges, circuits, magnets, transistors, and they [...]
