MIT engineers have found another method of generating current using tiny carbon particles that can create a current simply by contacting the liquid in it.

Liquid, a naturally soluble agent, takes electrons from particles that create motion that could be used to drive synthetic reactions or to control microscopic or nanoscale robots, scientists said.

“This system is new, and this method of generating energy is completely new,” said Michael Strano, professor of carbon P-dubs at MIT’s Chemical Engineering. “This invention is true in light of the fact that only a soluble agent has to run through the bed of these particles. This allows you to do electrical chemistry, but without it.”

In another study illustrating this miracle, experts showed that they could use this electric current to initiate a reaction known as electrical oxidation – a natural reaction of important substances in the composite industry.

Strano is the senior creator of the paper that is published today in Nature Communications. Lead authors of the study are MIT graduate Allout Tiansiang Liu and former MIT analyst Yuichiro Kunai. Several creators include former alumni Anton Cottrell, Postdocs Amir Kaplan and Hyuna Kim, graduate student Ji Zhang and ongoing MIT graduates Rafid Mollah and Yannick Itman.

Special features

The new revelation surpasses Streno’s research in carbon nanotubes – in empty cylinders made from a grid of carbon particles, with exceptional electrical properties. In 2010, Strano interestingly illustrated that carbon nanotubes can create ‘thermophores waves’. When a carbon nanotube is covered with a layer of fuel, the heat moving stroke or thermopower wave moves with the cylinder, creating an electric current.

This work encouraged Strano and his students to reveal the attached components of carbon nanotubes. They found that when a portion of the nanotube was covered with a polymer of telephone type, it created an asymmetry that made it possible to transfer the electric current from the casing to the casing of the cylinder and create an electric current. Those electrons can reduce the particles in the soluble material that are hungry for electrons.

To cut through this extraordinary power, experts crushed carbon nanotubes and placed them on pieces of paper-like material to create energy-producing particles. One side of each sheet was coated with a telephony national polymer and the analysts then cut the tiny particles, which could be any size or shape. For this study they created particles of 250 microns by 250 microns.

When these particles are lowered into natural soluble agents, for example acetonitrile, the soluble agents get stuck on the exposed surface of the particles and begin to attract electrons.

“Removes soluble electrons and the structure tries to adjust by removing electrons,” Streno says. “It has no modern battery science. It’s just a molecule and you leave it in soluble and it starts producing electric fields.”

Molecular energy

The particle current display can produce about 0.7 volts of energy per molecule. Experts in this study further showed that they can frame different types of particles in a small test tube. This “press bed” reactor produces enough energy to control a synthetic reaction called liquid oxidation, where the liquid is converted to aldehyde or ketone. In general, this reaction is not conducted using electronic chemistry, as it will require an additional amount of electricity from the outside.

“The filled bed reactor has been kept to a minimum so it is more adaptable in terms of application than a giant electrical chemical reactor,” Zhang said. “Particles can be shortened and they do not need external wires to conduct electrical chemical reactions.”

In future works, Strano wants to use this kind of energy age to create polymers that use only carbon dioxide as a starting material. In related initiatives, he has effectively created polymers that can self-repair using carbon dioxide as a structural element in interactions controlled by energy directed towards the sun. This work is driven by carbon induction, a synthetic reaction system that plants use to extract sugars from carbon dioxide using energy from the sun.
