So, yeah, thank you very much. And for the opportunity to give a talk here and show the introduction of what we are doing in the field of roll to roll UV nano printing, lithography. So Joanneum Rresearch located in Austria we have one vision with this process from nano goes macro. So I don't know if all of you are familiar with UV nano imprint.

And so we have the ability to produce very small structures on large scale, so on large and mechanically flexible substrates. And the first step we have to apply a coating resin. Then the next step is the molding. So the giving, the coating, the structures and the subsequent curing via UV and then the molding. And finally you have the structure. So it seems to be quite a simple process for a highly complex and very small structures.

And what we have established over the last decade that Joanneum Research is so called patterning pilot line where we start with the material. So we develop our own material, which is a anneal cure. It's like polyurethane or acrylics, which we can adjust to the specific needs a little bit later on. Then we have the simulation and the design by software tools to identify the optimal structure. Then we make the mastering. So with, for example, mala, so maskless laser lithography and the upscaling from the master by step and repeat to really have a full shim equipped with those structures. And we can do polymer shims on our own at Joanneum, we have partners in house due to the fact that we don't do this metallization by ourselves. And finally you have the production.

And so this little cure resin is a registered trademark of Joanneum and on the video below, you'll see that we can really tune it and tune it in the field of surface energy, refractive index elasticity. They are currently 70% biobased already. And I'm going to restart this video as you see with a needle, for example, you have a with a standard resin, you have really scratches and all this. And by adjusting our material, it perfectly fits the desired need. And so the pilot line on the right hand side, we have this mask, this laser or solar graphic for origination. Then we can make the tooling and mastering by this step and repeat. So to scale the small design up for the whole scheme and the replication. And finally of course the printing like 2 to 2.5 D for microfluidics micro optical structures or bionic structures like rabbits, moth, eye or lotus, which is shown here.

Some applications, bionic films, for example, is drag reduction where we mimic the sharkskin. So to reduce drag, if you glue this foil on airplanes like at Red Bull areas is equipped with those foils, it can result in fuel reduction, drag reduction, for example, planes or ships, then three from micro optical films for also medical diagnostics, but also for lighting industry. Microfluidic films are very interesting. Now, in the field of lab on foil and lab on chip systems, we can enhance the surface for the corrective films, but also create plasmonic films or like metal mesh, highly transparent conductive films. And here are some examples and enlargement of the picture shown before. This is realized by pilot line or open innovation testbed projects which we currently participate or coordinate like fabulous matlab and flex function to sustain. And so in the picture right below, for example, this is additional a new picture. It's holographic structure on land, recycled pet with some biodegradable resin for security features, like for banknotes, for labels or also for for tickets. And if you're interested in those projects, you can apply for micro crowns. But we can discuss this later on. And last but not least, another result from next gen microfluidics like this is a microfluidic channel shown in the left video with pillar arrays where the liquid perfectly distributes so for lab foil and lab on chip systems. And for example, if you need some other structures when you don't have these capillary effects so triangles with channels in between and you'll see when you drop some fluid you have a perfectly smooth distribution of the liquid. And so here the material, the design and the production of course are very, very important. And I think that we at joannuem research have the whole along the whole value chain, profound knowledge, which we like to offer interested companies. And so, yeah. Thank you for your interest. And I'm done.
