This baby should go head to head in a drag race with a F1 car, not a Corvette. Damn..this the fastest accelerating, road legal car I've ever seen. Too bad the owner is so full of himself
Technology and Health News
An amazing material was developed by Chinese scientists which is composed of carbon nanotube films and has a possible application (among otther) to produce the world's thinnest speakers.
Nanotubes, are a new carbon breed of material, which is 1000 times smaller than the width of a hair and can give sound with the "same quality of conventional speakers". This, however, does not require magnets of any sort or moving parts for that matter at all.
You can easilly imagine speakers everywhere: on walls, helmets, thinner ear plugs or even on your shirt.
This is possible because very thin carbon nanotube films, with the right frequency of electric currents, can emit sound. It also has a wide frequency response range and high sound pressure.
It also turns out that they are practical to build, and are even stretchable. Here is a video with the actual speackers embedded in a flag!
For the first time there was a negative charge exactly equal to 25 percent of that unit. Research in Nature magazine.
Since the electricity comes from the transport of electrons, it is logical to expect that the smallest load that can be transported is equal to the charge of a single electron. Under specific conditions, it is possible to observe portions of this fundamental unit. Even in these conditions, however, there have been observed only odd fractions of charge: third, fifth, seventh. In the last issue of Nature it was published the existence of a quasi-particle with a charge corresponding exactly a quarter of that of an electron.
In particular, these unique elementary particles, which have been precisely called "quasi-particles" to their particular nature, are formed when electrons are confined in a two-dimensional system, which forces them to interact strongly with each other. It is known that when a flow of electrons is confined in a two-dimensional plan of a semiconductor and it is applied simultaneously in a strong magnetic field perpendicular to this plane, the electrons have unusual quantum properties. In a research just published in Nature, in an electron gas, two-dimensional and ultra-pure, were detected within the fluid vortexes charges carrying exactly one quarter of the charge of an electron.
How can you convert waste into energy in the most efficient way possible? The secret is in riboflavin.
The microorganisms have the ability to change the chemistry of the environment. This is known for a long time, but if some of these can generate energy from the degradation of organic compounds has not yet been clarified. One answer comes from an American study published in Proceedings of the National Academy of Sciences (Pnas): BioTechnology researchers from the Institute of the University of Minnesota have found that the riboflavin, better known as vitamin B-2, is the key to the production of electricity by the microorganism Shewanella, a bacterium that is commonly found in water and soil.
