In science fiction films such as terminator, self-conscious machines can repair themselves, which is also of real interest to scientists and technology developers Researchers from the Israeli Institute of technology say self-healing electronics may be feasible, and there is technology to prove it
The research team led by Professor yehonadav Bekenstein of the school of materials science and engineering and the Institute of solids of the Israeli Institute of technology is studying perovskite nanoparticles because they have the potential to provide a green alternative to the toxic lead materials widely used in electronic products. In the process, they found something unexpected.
At the micro level, the team found that nanocrystals repair themselves by moving a hole (damage) through the region of the structure. The researchers were surprised. They developed a code to analyze the microscopic video and understand the dynamics and motion in the crystal.
The researchers found that after the damaged area is formed on the surface of nanoparticles, it will move to the area with stable internal energy, and finally be "spontaneously ejected". The researchers explained that through this self-healing process, the nanocrystals basically returned to an undamaged state.
Researchers at the Israel Institute of technology believe that this discovery is a key step in understanding the self-healing process of peridotite nanoparticles. The team also believes that peroxide nanoparticles should be used in solar panels and other electronic devices. The full text of the study was published in the journal advanced functional materials and provided in Willie online library. It is entitled "self repair of crystal voids in double peroxide nanocrystals is related to surface passivation".
