Boston: MIT engineers have developed a device that generates electricity under a brand new system. It uses fine ‘particles’ made of carbon nanotubes. These particles are immersed in an organic solution after which the current starts flowing from one place to another and thus even small robots can be run.
We know that carbon nanotubes are the best conductors of electricity and MIT scientists have found the best way to do this. They coated half of the nanotube with a Teflon-like polymer (in the form of a sheath) that allows electrons to travel from the sheath of the nanotube to the electron sheath. Now, as soon as the carbon nanotubes were immersed in the organic solution, they started drawing electrons from there and the flow of electricity started.
Michael Strano, an engineer at MIT, says the solution is full of electrons and the whole system keeps giving electrons to keep itself moderate. It does not use the chemistry of battery making, but the particles are kept in solution and thus the flow of electrons begins.
For its practical application, scientists first made a sheet of carbon nanotubes with a polymer on one side. The sheet was then divided into pieces of 250 micrometers. This is how distant nanotubes, called genes in scientific parlance, came into being.
The particles were then placed in a solution where they were arranged in a row. Each particle produces 0.7 volts of electricity, which is sufficient for the oxidation reaction of alcohols. In this process, the alcohol is converted to aldehyde or ketone and this is a common practice in the chemical industry.
Following this success, experts say that small robots can be powered by particle power, or that systems from their environment can use it.
