Simulating nature’s cosmic laboratory, one helium droplet at a time

27-Mar-2019

Two astronomers from the Max Planck Institute for Astronomy and from the University of Jena have found an elegant new method to measure the energy of simple chemical reactions, under similar conditions as those encountered by atoms and molecules in the early solar system. Their method promises ...

Revealing the secret of the vacuum for the first time

20-Mar-2019

For most people, a vacuum is an empty space. Quantum physics, on the other hand, assumes that even in this lowest-energy state, particles and antiparticles still fluctuate. This is an assumption for which no clear evidence has been provided as yet. A new research group at the University of Jena ...

A quadrillionth of a second in slow motion

Observing and controlling ultrafast processes with attosecond resolution

22-Feb-2018

Many chemical processes run so fast that they are only roughly understood. To clarify these processes, a team from the Technical University of Munich (TUM) has now developed a methodology with a resolution of quintillionths of a second. The new technology stands to help better understand ...

High resolution without particle accelerator

Physicists are first to achieve optical coherence tomography with XUV radiation at laboratory scale

10-Aug-2017

A visit to the optometrist often involves optical coherence tomography. This imaging process uses infrared radiation to penetrate the layers of the retina and examine it more closely in three dimensions, without having to touch the eye at all. This allows eye specialists to diagnose diseases such ...

The odor of stones

09-Feb-2016

Diatoms are unicellular algae that are native in many waters. They are a major component of marine phytoplankton and the food base for a large variety of marine organisms. In addition, they produce about one fifth of the oxygen in the atmosphere and are therefore a key factor for our global ...

Tunable materials clear the way for advanced optics

18-Jan-2016

Now you see it, now you don’t: In books and movies, wizards use magic spells to easily change things from a solid to see-through state. However, in reality, materials with properties called phase transition can pull off a similar trick, changing from clear to cloudy depending on the temperature ...

Synthetic Batteries for the Energy Revolution

Redox-flow battery based on organic polymers and water presented

23-Oct-2015

Sun and wind are important sources of renewable energy, but they suffer from natural fluctuations: In stormy weather or bright sunshine electricity produced exceeds demand, whereas clouds or a lull in the wind inevitably cause a power shortage. For continuity in electricity supply and stable ...

Pushing the limits of lensless imaging

23-Sep-2015

Using ultrafast beams of extreme ultraviolet light streaming at a 100,000 times a second, researchers from the Friedrich Schiller University Jena, Germany, have pushed the boundaries of a well-established imaging technique. Not only did they make the highest resolution images ever achieved with ...

Speed at its limits

Physicists develop ultra-fast semiconductor nano-lasers

01-Oct-2014

One thousand billion operations per second – this peak value is achieved by semiconductor nano-lasers developed by physicists at the University of Jena together with their colleagues from Imperial College London. As the researcher report in the current issue of the journal of „Nature Physics“, ...

Chemists let fluorescent sugar sensors ‘calculate’

23-Jun-2014

In a chemistry lab at the Friedrich Schiller University Jena (Germany): Prof. Dr. Alexander Schiller works at a rectangular plastic board with 384 small wells. The chemist carefully pipets some drops of sugar solution into a row of the tiny reaction vessels. As soon as the fluid has mixed with ...
