Tailored Polymers from a Printer

Efficient chain transfer for 3D-printing of tough photopolymers

10-Jul-2018

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 printing, ...

Breaking the bond: To take part or not?

10-Jul-2018

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical ...

Perfect Images: A High-Performance Microscope Dangling From Bungee Cords

Patented vibration damping system enables images of highest quality

10-Apr-2018

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 of ...

Roton quasiparticles observed in quantum gas

07-Mar-2018

An Innsbruck team of experimental physicists, in collaboration with theorists from Innsbruck and Hannover, has for the first time observed so-called roton quasiparticles in a quantum gas. Empirically introduced by Landau to explain the bizarre properties of superfluid liquid Helium, these ...

Nanostructures made of previously impossible material

Incorporating high proportions of foreign atoms into crystals

07-Mar-2018

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 an ...

Photosynthetic microalgae as biocatalysts

The biocatalytic production of chemicals should become considerably more sustainable

06-Mar-2018

A carpet of blue-green algae can literally ‘cloud’ the summer’s swimming pleasure at the lake. This is caused by a few strains of photosynthetically active microalgae, also known as cyanobacteria. Other harmless strains of cyanobacteria have great potential for biotechnological applications and ...

Plastic bags that cannot breathe

Optimized enzyme variant can degrade plastic under anaerobic conditions

05-Mar-2018

Many bio-plastic bags have no place in the garbage. They dissolve too slowly in oxygen-deficient environments like biogas plants and when incinerated they are a burden to the environment. A research project at the Austrian Centre of industrial Biotechnology (acib) hunts for enzymes, which ...

An atom full of atoms

Exotic state of matter

26-Feb-2018

What is inside an atom, between the nucleus and the electron? Usually there is nothing, but why could there not be other particles too? If the electron orbits the nucleus at a great distance, there is plenty of space in between for other atoms. A "giant atom" can be created, filled with ordinary ...

Combating sulphuric acid corrosion at wastewater plants

Microbial induced concrete corrosion causes massive damage to wastewater plants

26-Feb-2018

Wastewater systems are integral to infrastructure in every community. In an ideal world, they operate smoothly and are long-lasting. But biogenic transformation processes in sewage and water treatment systems are a “natural enemy” of conventional plants, frequently causing damage to concrete and ...
