Glass is more transparent – Berlin week

Adlershof. for about 100 years Adlershof is the site were developed to the modern technologies and be. Empennage for aircraft, cameras, make the noise visible, and things that are so small that they remain hidden.

As the nanotechnology, the Professor Erhard Kemnitz developed. Which is now patented, so at least not quite secret, but still barely visible.

The professor, whose main occupation professor at the Institute of Chemistry, Humboldt-University, holding a small plastic bowl in hand. Here there is the mysterious solution that consists mainly of Magnesiumflourid. The quantity in the vessel is hardly measurable, and the individual particles are incredibly small, just at the nanoscale – one billion nanometers give a meter

And this solution can ensure that glass is much more transparent.. “Ordinary glass absorbs up to eight percent of light, which is not exactly positive for glasses or optical devices. Previously antireflective layers must be deposited consuming in a vacuum and often in multiple layers. Our solutions, consisting of alcohol, water and the Metallflourid, can at are used room temperature, “says the professor.

In order to bring his invention to the market, the 63-year-old has founded a company and rented in a building on the Rudow Chaussee room for four laboratories and two offices . Licenses for coating glass has been awarded the small company. The necessary solutions for coating are virtually set in Adlershof in hand. And that happens quite unspectacular, in a 60-liter plastic reactor with stirrer and without bang, smoke and stench. Around 100 liters of the final solution contained 250 grams of nanoparticles to allow 5000 square meters of glass are coated. The light transmittance is by turning off the reflection thereafter up to 99.9 percent. Meanwhile, the nanoparticles can be incorporated into plastics and are therefore used for the production of modern, lighter lenses.

“The equipment for the glass coating can continue to be used and more expensive, the application of our nanotechnology also not the coating,” promises Professor Erhard Kemnitz.

The patents for the technology has the Humboldt-Uni introduced in the company was founded, is thus still involved. By 2018, Erhard Kemnitz works in parallel as university professor and his company. When production of the 150 leased square should be too extensive, he wants to build his own company building.

applications for the nanoparticles from Adlershof are plenty. In addition to the coating of windows photo lenses can be even more effective, and also in the dental field the Magnesiumflourid can be usefully employed.

And even the surface of computer screens can be made more resilient.
