More sustainable recycling of plastics

Chemists have developed a method for more sustainable recycling of polyethylene-like plastics

22-Feb-2021

Plastics belong to the most widely used materials, and they are vital components of all modern technologies. So far, it has been possible to recycle these valuable materials only to a limited extent. In order to offer novel solutions, chemists of Professor Stefan Mecking’s group at the University ...

Neither liquid nor solid

Discovery of liquid glass sheds light on the old scientific problem of the glass transition

07-Jan-2021

An interdisciplinary team of researchers from the University of Konstanz has uncovered a new state of matter, liquid glass, with previously unknown structural elements – new insights into the nature of glass and its transitions. While glass is a truly ubiquitous material that we use on a daily ...

Shining a light on nanoscale dynamics

Watching metamaterials at work in real time using ultrafast electron diffraction

26-Nov-2020

Physicists from the University of Konstanz, Ludwig-Maximilians-Universität München (LMU Munich) and the University of Regensburg have successfully demonstrated that ultrashort electron pulses experience a quantum mechanical phase shift through their interaction with light waves in nanophotonic ...

Attosecond boost for electron microscopy

Attosecond time resolution in a transmission electron microscope by combining it with a continuous-wave laser achieved

13-Nov-2020

Electron microscopes provide deep insight into the smallest details of matter and can reveal, for example, the atomic configuration of materials, the structure of proteins or the shape of virus particles. However, most materials in nature are not static and rather interact, move and reshape all ...

Directly coupling two closely located nanoscale sensors

Coupled oscillations

02-Dec-2019

They look like toothpicks, but much, much smaller: 10,000 times shorter and 1,000 times thinner. The research team around physicist Professor Eva Weig succeeded in constructing nanopillars so closely together that they can be coupled via the strain field and succinctly oscillate together. This ...

Heat transport through single molecules

International team of researchers with participation of the University of Konstanz achieves breakthrough in the area of heat transport at molecular scales

22-Jul-2019

Combining novel theoretical and experimental approaches, researchers from the University of Michigan (USA), Kookmin University (South Korea), the University of Konstanz (Germany) and the Okinawa Institute of Science and Technology Graduate University (Japan) have successfully measured and ...

Obtaining polyester from plant oil

New catalysis concept for obtaining polyester from castor oil

14-Dec-2018

The development of future technologies that are not based on mineral oil and can be used for producing chemicals and plastics is one of the major tasks in modern materials science and a key challenge that needs to be addressed if sustainable industrial production is to have a future. A range of ...

Tilted pulses

Extremely short and specifically-shaped electron pulses for materials studies in the femtosecond and attosecond range

06-Sep-2018

Our world is basically made up of atoms and electrons. They are very small and move around very rapidly in case of processes or reactions. Although seeing atoms is nowadays possible, for example with modern electron microscopes, tracking atomic movements requires ultrashort measurement periods in ...

The limits of friction

03-Apr-2018

Friction is created when two surfaces slide one on top of the other. Since this consumes additional energy, this so-called sliding friction is considered an irksome yet inevitable aspect of dynamic processes. However, to set a stationary object in motion, its static friction must be overcome ...

Stable quantum bits

13-Dec-2017

Milestone on the path to the quantum computer: Scientists of the University of Konstanz, Princeton University, and the University of Maryland develop a stable quantum gate for two-quantum bit systems made of silicon. The quantum gate is able to perform all necessary basic operations of the ...
