Organic cation transporters: study provides insights for the first time
Monoamines are neurotransmitters in the central and peripheral nervous systems and they also transmit signals between cells and the brain. This transmission is followed by their reuptake into the cells by means of transporters. While the specific monoamine transporters have already been well studied, not enough is known about the organic cation transporters, which are high-capacity monoamine transporters.

How to fire projectiles through materials without breaking anything
How to fire projectiles through materials without breaking anything
When charged particles are being shot through ultra-thin layers of material, sometimes spectacular micro-explosions occur, sometimes the material remains almost intact. This has now been explained at the TU Wien. It sounds a bit like a magic trick: Some materials can be shot through with fast, electrically charged ions without exhibiting holes afterwards.

Faster and more Efficient Computer Chips Thanks to Germanium
Faster and more Efficient Computer Chips Thanks to Germanium
TU Wien (Vienna) has succeeded in making a new type of material usable for chip technology. This enables faster, more efficient computers and new types of quantum devices. Our current chip technology is largely based on silicon. Only in very special components a small amount of germanium is added. But there are good reasons to use higher germanium contents in the future: The compound semiconductor silicon-germanium has decisive advantages over today's silicon technology in terms of energy efficiency and achievable clock frequencies.

Profiling of sweet-fatty molecules on cell surfaces.
Profiling of sweet-fatty molecules on cell surfaces.
New method enables measurement of glycolipids; now, for example, the relevance in cancer will be investigated So-called glycolipids, or "sweet-fatty" molecules, are a relatively unknown group among the body's diverse lipids. A method developed by an Austrian team led by chemist Evelyn Rampler of the University of Vienna has now provided deeper insights into the functioning of certain glycolipids, which are located, among other things, on the surfaces of stem cells.

Three Eyes See More than Two
Three Eyes See More than Two
Researchers at TU Vienna and FHI Berlin succeeded in monitoring a catalytic reaction with three different microscopies under exactly the same conditions in real time. In this way, information is obtained that none of the methods alone could reveal. One has to look very closely to exactly understand what processes take place on the surfaces of catalysts.

Recycling Greenhouse Gases
Recycling Greenhouse Gases
CO2 and methane can be turned into valuable products. But until now the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. Wherever the production of harmful greenhouse gases cannot be prevented, they should be converted into something useful: this approach is called "carbon capture and utilisation".

Miniaturized Lab-on-a-Chip for real-time Chemical Analysis of Liquids
Miniaturized Lab-on-a-Chip for real-time Chemical Analysis of Liquids
A fingertip-sized chip replaces bulky laboratory equipment. An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In analytical chemistry, it is often necessary to accurately monitor the concentration change of certain substances in liquids on a time scale of seconds.

Why Some Bubbles Move Faster
Why Some Bubbles Move Faster
By Susanne Filzwieser Why do large gas bubbles in viscoelastic liquids (such as polymer and protein solutions) rise so much faster than expected? An open question with great relevance for industrial production processes. Researchers at TU Graz and TU Darmstadt have now found an explanation. Further at the end of the text It is a puzzle long known among experts and very relevant in many industrial production processes: a jump discontinuity in the rise velocity of gas bubbles in so-called viscoelastic fluids.

Moving towards 80,000 Hours of Fuel Cell Operation and Beyond
Moving towards 80,000 Hours of Fuel Cell Operation and Beyond
By Merit Bodner Hydrogen and fuel cell technologies as viable and sustainable approaches to a renewable energy supply chain are experiencing unprecedented attention. As the industry is growing, its view is becoming increasingly holistic. Novel and innovative ways of maximising product utilisation and minimising product footprint are crucial in establishing a true alternative to conventional solutions.
