Magnetic resonance makes the invisible visible

Hyperpolarised water boosts signal intensities of proteins, DNA, and membranes

20-May-2022

A small group of researchers including Dennis Kurzbach from the Faculty of Chemistry of the University of Vienna just published in "Nature Protocols" an advanced NMR (Nuclear Magnetic Resonance) method to monitor fast and complicated biomolecular events such as protein folding. For example, ...

Electronic skin: multisensory hybrid material

Even more sensitive than a human fingertip

18-May-2022

The “smart skin” developed by Anna Maria Coclite is very similar to human skin. It senses pressure, humidity and temperature simultaneously and produces electronic signals. More sensitive robots or more intelligent prostheses are thus conceivable. The skin is the largest sensory organ and at the ...

The platinum riddle

How a chemical reaction takes place that, at first glance, should not be possible at the temperatures observed

05-Apr-2022

What happens when a cat climbs onto a sunflower? The sunflower is unstable, will quickly bend, and the cat will fall to the ground. However, if the cat only needs a quick boost to catch a bird from there, then the sunflower can act as a "metastable intermediate step". This is essentially the ...

Quantum sensors: Measuring even more precisely

Better measurements with little extra effort

25-Mar-2022

Two teams of physicists led by Peter Zoller and Thomas Monz at the University of Innsbruck, Austria, have designed the first programmable quantum sensor, and tested it in the laboratory. To do so they applied techniques from quantum information processing to a measurement problem. The innovative ...

Terahertz radiation source: Compact and simple

A novel, simple and extremely compact radiation source for terahertz waves: The possible applications are manifold.

13-Jan-2022

Terahertz radiation has a wavelength of typically a little less than one millimetre - a technically difficult range. Electromagnetic waves with longer wavelengths can be generated with ordinary electronic components (such as transistors) and antennas. Smaller wavelengths can be obtained with ...

New State of Matter: Crystalline and Flowing at the Same Time

Particles with pompom-like structure

13-Dec-2021

The predictions of researchers that certain particles of matter with sufficiently high density would form a new state - crystalline and flowing at the same time - could be confirmed in the laboratory. More than 20 years ago, researchers predicted that with sufficiently high density certain ...

Detective work on the fuel cell

Researchers are investigating new materials that can be used to reduce the operation temperature of solid oxide fuel cells: To do so, they apply an innovative method

02-Dec-2021

Solid oxide fuel cells consist of three important parts: an anode, a cathode and an electrolyte. While oxygen is incorporated into the cathode, oxygen is then transported through the electrolyte to the anode, where oxygen reacts with hydrogen to water. The fuel cell is able to convert the energy ...

How Cells Feel Curvature

Scientists find mechanism that allows cells to sense the curvature of tissue around them

22-Nov-2021

Cells in your body cannot see, but they can feel their surroundings and their own shape. Scientists at the University of Mons and the Institute of Science and Technology (IST) Austria now showed via both - experiments and theory - how cells can sense the curvature of tissue around them and how ...

Researchers have succeeded for the first time in analyzing nanovesicles and proteins in parallel

This is important to determine the quality of a sample and to clearly attribute effects to the transport vesicles

26-Oct-2021

To transport substances between cells, they are packaged in nanovesicles. The small vesicles are surrounded by a lipid layer and fuse with the cell membrane at their destination. Within the body, they control many important processes. However, it is still unclear whether the influence in ...

The quantum refrigerator

Computer simulations show how quantum fields could be used to break low-temperature records

30-Jul-2021

At first glance, heat and cold don't have much to do with quantum physics. A single atom is neither hot nor cold. Temperature can only be defined for objects that consist of many particles. But at TU Wien, in collaboration with Freie Universität Berlin, Nanyang Technological University in ...
