A group of researchers from the United States, Spain, Belgium and Japan, who were doing a nanotube trial, found that if you add boron to carbon, nanotubes run away as if they were sponges, and in addition to floating well in the water, they absorb the oil and oil that may be in the water.
Nanotutated material can gain weight a hundred times by absorbing the oil. Once the oil is compressed and emptied, as we do with conventional sponges, the process can be repeated 10,000 times, so these special sponges can be used over and over without modifying their properties.
