How can we remove heat from computer chips as fast as possible' At TU Wien, a metal compound has now been identified that is particularly well suited for this purpose. A thermos bottle has the task of preserving the temperature - but sometimes you want to achieve the opposite: Computer chips generate heat that must be dissipated as quickly as possible so that the chip is not destroyed.

Researchers at TU Graz and the University of Graz, together with experts from France, have succeeded in imaging surface phonons in 3D for the first time. This success could accelerate the development of new, efficient nanotechnologies. Whether for microscopy, data storage or sensor technology, many advanced technological applications that require specific functions rely on the structure of the electromagnetic field near the surfaces of materials.

Carbonized plants contain harmful free radicals Every year, an estimated four percent of the world's vegetated land surface burns, leaving more than 250 megatons of carbonized plants behind. For the first time, a study by the University of Vienna has now recorded elevated concentrations of environmentally persistent free radicals (EPFR) in these charcoals - in some cases even up to five years after the fire.

Older than expected: Teeth reveal the origin of the tiger shark
With a total length of up to 5.5m, the tiger shark is one of the largest predatory sharks known today. This shark is a cosmopolitan species occurring in all oceans worldwide. It is characterized by a striped pattern on its back, which is well marked in juveniles but usually fades in adults.

Moiré effect: How to twist material properties
Moiré effect: How to twist material properties
2D materials have triggered a boom in materials research. Now it turns out that exciting effects occur when two such layered materials are stacked and slightly twisted. The discovery of the material graphene, which consists of only one layer of carbon atoms, was the starting signal for a global race: Today, so-called "2D materials" are produced, made of different types of atoms.

Agricultural biodiversity
International survey shows different perceptions in science and practice To minimize negative impacts of agriculture on biodiversity and related ecosystem services, "biodiversity-friendly" management is needed. Why scientific results are rarely translated into agricultural practice could be explained by their different perceptions of agricultural biodiversity, according to the results of a recent survey of European scientists and farmers.

TU Graz Researchers Identify Chemical Processes as Key to Understanding Landslides
The study results are based on investigations of repeated mass movements and are expected to benefit planning, maintenance, and development of transportation infrastructure in affected areas. Mass movements such as landslides and hill-slope debris flows cause billions of euros in economic damage around the world every year.

Fear of COVID-19 : Psychological, not environmental factors are important
Fear of COVID-19 : Psychological, not environmental factors are important
During pandemics, protective behaviors need to be motivated by effective communication. A critical factor in understanding a population's response to such a threat is the fear it elicits, since fear both contributes to motivating protective responses, but can also lead to panic-driven behaviors. Furthermore, lockdown measures affect well-being, making it important to identify protective factors that help to maintain high perceived levels of health during restrictions.

How do good metals go bad?
How do good metals go bad?
New measurements have solved a mystery in solid state physics: How is it that certain metals do not seem to adhere to the valid rules? We all have a clear picture in mind when we think of metals: We think of solid, unbreakable objects that conduct electricity and exhibit a typical metallic sheen. The behaviour of classical metals, for example their electrical conductivity, can be explained with well-known, well-tested physical theories.

Fossilized feeding frenzy: 47 million year old fly found with a full belly
An international team of scientists with Fridgeir Grímsson from the University of Vienna has found a previously unknown fossil fly species in old lake sediments of the Messel Pit, a UNESCO World Heritage Site in Germany. In the stomach of the fossil insect, pollen from various plants could be detected, which allows rare insights into the feeding behavior, the ecology and the role of the fly as a pollinator.

Robots learn faster with quantum technology
Robots learn faster with quantum technology
Artificial intelligence is part of our modern life by enabling machines to learn useful processes such as speech recognition and digital personal assistants. A crucial question for practical applications is how fast such intelligent machines can learn. An experiment at the University of Vienna has answered this question, showing that quantum technology enables a speed-up in the learning process.

New Approach Found for Energy-Efficient AI Applications
Researchers at TU Graz demonstrate a new design method for particularly energy-saving artificial neural networks that get by with extremely few signals and - similar to Morse code - also assign meaning to the pauses between the signals. Most new achievements in artificial intelligence (AI) require very large neural networks.

Promising metallodrug candidate for tumour therapy
BOLD-100/KP1339 is a ruthenium-based anticancer agent that has been decisively co-developed at the University of Vienna and which has shown promising results in clinical trials in cancer patients. However, the mode of action of this metal compound has not yet been fully elucidated. Researchers from the University of Vienna and the Medical University of Vienna have now been able to demonstrate that BOLD-100 binds to ribosomal proteins in tumour cells.

Women and the Global South are strikingly underrepresented Most publications in leading scientific journals are by male authors from English-speaking countries. This changes only slowly, according to a recent study on diversity in top authorship, concludes Bea Maas from the University of Vienna. Her new study examines the (non-existent) diversity in top authorship in science.

Microchips of the Future: Suitable Insulators are Still Missing
Until now, hexagonal boron nitride was considered the insulator of choice for miniaturised transistors. New investigations by TU Wien (Vienna) show: this may not be the way to go. For decades, there has been a trend in microelectronics towards ever smaller and more compact transistors. 2D materials such as graphene are seen as a beacon of hope here: they are the thinnest material layers that can possibly exist, consisting of only one or a few atomic layers.
