Glass Nanobots-new invention in Science

Glass Nanobots Absorb Toxins

                  Ananobot particle made from glass is being developed that can absorb pollutants from contaminated water.

The glass particles act like sponges by attracting and binding contaminants to themselves and expanding eight times in size during the process.

But unlike a sponge, these nanobots are hydrophobic, meaning they don't absorb water.

Scientists claim this new technology could be used to clean petroleum spills or other hazardous chemicals from our waterways. After the particles are dropped into the water, they collect pollutants and then rise to the surface when fully expanded. The particles are then skimmed from the surface, cleaned and placed back into the water to repeat the process.

Water Drop Lens

      Physicist and inventor, Bruno Berge, has created a liquid optical lens.Using a process known as electro-wetting, a water drop is deposited on a metal substrate and covered by a thin insulating layer. When a voltage is applied to the metal, it modifies the angle of the liquid drop.

The liquid lens is comprised of two liquids, water and oil, one is a conductor while the other is an insulator. A variation in the voltage causes a change to the curvature of the liquid to liquid interface, which changes the focal length of the lens.

           The use of liquids allows for low cost construction. There are no moving parts and electrical consumption is extremely low. The lens has a large inverse focal length range, quick response, high optical quality and can operate in a wide temperature range.
