Strange Things
Published on Mar 21, 2019
For the first time in history and with our current technology, researchers have produced nano-objects that can shrink "alone". First, the researchers assembled 3D objects in a special hydrogel, then an acid caused the gel and its contents to shrink. The 3D design thus became an object ten or thousand times smaller, without distortions or defects. SOURCE: https://www.ufo-spain.com
