Some surfaces are wetted by water, others are water-repellent. TU Wien (Vienna), KU Leuven and the University of Zürich have discovered a robust surface whose adhesive and wetting properties can be switched using electricity. This remarkable result is featured on the cover of Nature magazine.
To investigate the wetting of the surface, an instrument was built specially for this purpose, in which a liquid drop is brought on the surface through a very thin glass tube. The drop is made bigger and smaller while at the same time its shape is recorded. Whether the drop shape is flat or more rounded depends on the properties of the surface.
An ever-growing number of coatings, including varnishes and printing inks, as well as tooth fillings, are cured with light. Yet, homogenous, tailored, polymer networks cannot be produced, and the materials tend to be brittle, which limits the use of photopolymers in applications like 3D pri ... more
To produce images of individual atoms, a microscope shouldn't shake. A patented vibration damping system developed at the TU Wien enables images of the highest quality. It is one of the most accurate measurement instruments available today: the high-performance microscope at the Institute o ... more
When you bake a cake, you can combine the ingredients in almost any proportions, and they will still always be able to mix together. This is a little more complicated in materials chemistry. Often, the aim is to change the physical properties of a material by adding a certain proportion of ... more
