Materials synthesis research and study in terapascal range for the first time

Traveling to the centre of planet Uranus

13-May-2022

Jules Verne could not even dream of this: A research team from the University of Bayreuth, together with international partners, has pushed the boundaries of high-pressure and high-temperature research into cosmic dimensions. For the first time, they have succeeded in generating and ...

Polyethylene degradation in the environment

02-May-2022

Polyethylene, a plastic that is both cheap and easy to process, accounts for nearly one-third of the world’s plastic waste. An interdisciplinary team from the University of Bayreuth has investigated the progressive degradation of polyethylene in the environment for the first time. Although the ...

Atomic Terahertz-vibrations solve the enigma of ultrashort soliton molecules

Findings may help to develop particularly fast chemically sensitive microscopes that can be used to identify materials

25-Apr-2022

Stable packets of light waves – called optical solitons – are emitted in ultrashort-pulse lasers as a chain of light flashes. These solitons often combine into pairs with very short temporal separation. Introducing atomic vibrations in the terahertz range, researchers at the Universities of ...

Researchers develop catalyst for sustainable production of important chemical precursors

Outstanding selectivity is coupled with an unusually high efficiency

04-Apr-2022

The alpha-olefins, consisting of carbon and hydrogen, are the most important precursors in the chemical industry. Researchers at the University of Bayreuth present a discovery in the journal “Science” that opens up previously unimagined prospects for the design and the selective as well as ...

Learning from dust: health risks of microparticles

Properties such as size, shape and surface condition of microparticles influence their hazardous potential for humans

20-Jan-2022

Researchers at the University of Bayreuth want to find out the consequences of inhaled microplastics. In order to better understand them, they have conducted an interdisciplinary study to find out how the health risks of particles such as soot, grinding dust or asbestos are related to their ...

Supposedly similar microplastic particles show different levels of toxicity

"Our study impressively shows how problematic it is to make generalised statements about the health or ecological effects of microplastics"

16-Dec-2021

More and more studies worldwide are looking into the effects of microplastics, especially with regard to the environment and health. They often use spherical polystyrene microparticles and have arrived at partly contradictory results. An interdisciplinary research team at the University of ...

Researchers discover carbon material with unique structure

"The material we synthesized is a hermaphrodite: for the first time, it forms a bridge between crystalline and amorphous, i.e. completely disordered, structures"

29-Nov-2021

Researchers at the University of Bayreuth, together with partners in China and the USA, have for the first time produced a carbon material that does not have the strictly ordered structures of a crystal, but is not amorphous either. It is paracrystalline diamond with unique optical, mechanical ...

Rainfall causes microplastic transport into the atmosphere

Up to 100 trillion microplastic particles could enter the atmosphere every year as a result of rainfall

22-Nov-2021

Oceans, lakes and rivers often contain a large number of microplastic particles on their surface. Impacting raindrops cause many droplets with an almost equally high concentration of microplastics to be thrown up into the air. When they evaporate in the air, the particles enter the atmosphere. ...

Separated only by quadrillionths of a second: Ultrashort flashes of light combined precisely and quickly

03-Nov-2021

Ultrashort flashes of light lasting less than a quadrillionth of a second are fast growing in technological importance. In laser sources, pairs and groups of light flashes can be created instead of individual flashes. Similar to the chemically bonded atoms in a molecule, they are coupled with ...

Artificial opals measure temperature and time

Researchers discover novel sensors

30-Sep-2021

Due to their iridescent colors, opals have been considered particularly precious gemstones since antiquity. The way these stones shimmer is caused by their nanostructures. A research group led by Prof. Dr. Markus Retsch at the University of Bayreuth has produced colloidal crystals mimicking such ...
