According to the report of NHK TV station, the research team of the University of Tokyo in Japan developed for the first time in the world a glass that can be restored to its original state by pressing and holding the cross section after breaking. This type of glass was developed by a research team led by professors Aiota Hiroshi of the University of Tokyo and Dr. Iwasawa Ryo of the PhD students. The team was originally engaged in the development of new types of adhesives, and they stumbled upon the hard, smooth-feeling material that restored the initial state of self-healing.

The English name of the substance is “poly[thioureas] and ethylene glycolâ€. After the glass made of this material breaks down, it can be restored by holding down the profile for several tens of seconds, and the strength will be restored after a few hours. .
Previously discovered materials that can repair themselves even if damaged in a room temperature environment are relatively soft materials like rubber. Previously, it was believed that materials that were as hard as glass were difficult to achieve.
Liu Zeyou stated that he was skeptical at the time of his discovery, pointed out various problems when writing his thesis, and repeatedly conducted experiments. Being able to repair the glass will be different from the previous one that was broken and thrown away. If you can become an environmentally friendly material, you will be very happy.
