These researchers are engaged in nanotechnology and their research has a narrow specific application

One asked me: "Researchers have developed "Highly Floatable Superhydrophobic Metallic Assembly for Aquatic Applications"
They claim that  There’s potential for unsinkable boats, puncture-proof life jackets....This could be a real chance the researchers write, to innovate “conventional floating devices and watercrafts that have been used for millennia." More
 What do you think about it?"

I answered him: "I think this is not true. These researchers are engaged in nanotechnology and their research has a narrow specific application. 
They applied capillary force in the opposite direction. It matters with a very small distance between the plates (figure b, c, d). 
When the distances are large enough, the capillary effect will disappear and other physical quantities will prevail. (figure a)"
