2. On April 28th, 2008, the Criminal Investigation Brigade of Dongsheng District Public Security Bureau in Ordos City, Inner Mongolia Autonomous Region cracked a gold theft case. In order to steal gold, the shopkeeper specially cleaned the gold necklace with highly corrosive aqua regia. Using chemical reaction to steal gold from customers' jewelry, the longer the soaking time, the more gold is stolen.
3. Two scientists, Laue and Frank, won the physics prizes of 19 14 and 1925, and the Nazi government of Germany wanted to confiscate their Nobel Prizes. They moved to Denmark and asked Bohr, a Danish colleague and physics prize winner-1922, to help them keep them.
1940, Nazi Germany occupied Denmark, and Hevesy, a Hungarian chemist who worked in the laboratory with Bohr (winner of the 1943 chemistry prize), helped him think of an idea: put the medal in "aqua regia" (a mixture of hydrochloric acid and nitric acid), and the pure gold medal would dissolve. Bohr then put the solution bottle on the shelf of the laboratory, and the Nazi soldiers who came to search did not find the secret.
After the war, the gold in the solution bottle was reduced and sent to Stockholm, where it was recast with the same mold. 1949 When Zhao was returned, a grand medal return ceremony was held in Chicago, USA, where Frank worked at that time.
