Akira Fujishima, an honorary professor at Tokyo University of Science, who is known worldwide for his research on "photocatalysts" that are widely used for decomposing harmful substances, gave a lecture at his alma mater in Toyota City, Aichi Prefecture, and conducted experiments through experiments. I conveyed the fun of science.
Akira Fujishima (79) from Toyota City visited Sagiri Elementary School, his alma mater in the city, and gave a delivery class in front of 30 children and local people.
Mr. Fujishima is known worldwide for his research on "photocatalysts" that are widely used for decomposing harmful substances. In class, when you first apply "photocatalysts" using slides, the glass does not become cloudy, so the car I explained that it is used for coating the side mirrors of the above, and that it is widely used because it decomposes dirt with the sunlight when it is applied to the building, so it is hard to get dirty.
After that, the children conducted an experiment in which the photocatalyst was actually applied to the glass and steamed, and it was confirmed that the place where the photocatalyst was applied did not become cloudy.
In addition, he conducted an experiment in which water did not spill even when the cup filled with water was covered with paper and turned upside down, and Mr. Fujishima explained that it was due to surface tension and pressure.
A 6th grade boy said, "I enjoyed the experiment."
Mr. Fujishima said, "It's really fun because it's my alma mater. I'm glad that the children worked hard on the experiment. I want them to read the biography of scientists to get familiar with science."
