Snapshots from the quantum world

A research collaboration can read out optically previously indistinguishable spin states by using a newly developed spectroscopy method

05-Jan-2022

The alternation between singlet and triplet states of electron pairs in charge-separated states plays an important role in nature. Presumably, even the compass of migratory birds can be explained by the influence of the geomagnetic field on the magnetic interplay between these two spin states. ...

Binary mesocrystals from the nanobuilding kit

07-Dec-2021

Research team led by Constance produces three-dimensional mesocrystals from two different types of nanocrystals - platinum and magnetite - for the first time. This lays the foundation for the synthesis of novel nanostructured solids with previously unexplored properties. Mesocrystals are a class ...

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 ...

Light-induced shape shifting of MXenes

Femtosecond light creates switchable nano-waves in MXenes and moves the materials’ atoms at a record-breaking speed

03-Sep-2021

Ultrafast laser spectroscopy allows to observe the motion of atoms at their natural time scales in the range of femtoseconds, the millionth of a billionth of a second. Electron microscopy, on the other hand, provides atomic spatial resolution. By combining electrons and photons in one instrument, ...

Demystifying the 'Parkinson Protein'

Research team succeeds in directly observing the membrane binding of α-synuclein in living cells

11-Mar-2021

The protein α-synuclein is one of the most abundant proteins in the human brain. It is often referred to as the "Parkinson protein", as deposition of this protein in brain cells is a hallmark of Parkinson's disease. Despite the high interest of biomedical research in the protein, many questions ...

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 ...

Real-time observation of enzymatic processes on DNA

Insights into the molecular processes involved in the detection of DNA strand breaks

05-May-2020

DNA strand breaks can contribute to the development of cancer and the ageing process. Researchers from the Departments of Biology and Chemistry of the University of Konstanz have now been able to observe in real time the molecular processes that take place at DNA strand breaks by means of ...

New technique for in-cell distance determination

21-Mar-2019

Researchers from the University of Konstanz, Bielefeld University and ETH Zurich demonstrate for the first time that the pulsed EPR technique RIDME (relaxation-induced dipolar modulation enhancement) can be used for in-cell distance determination in biomacromolecules. Applied within the cell, ...

Sweet lysine degradation

Glucogenic lysine degradation found for the first time

03-Dec-2018

In fact, they were looking for a specific enzyme. What they found is something so fundamental that their new findings might well find their way into textbooks. Referred to here is the amino acid lysine, which is an important building block in proteins. In bacteria and many other organisms, lysine ...
