Novel approach to the storage of solar energy

Molecular approach enables light-driven photochemistry in the dark for the first time

21-Sep-2020

Using the energy from the sun as efficiently as nature does and converting it into chemical energy could drastically reduce global CO2 emissions. A research team from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Friedrich Schiller University Jena has now come one step ...

Tellurium makes the difference

International research team discovers unusual molecular structures

10-Aug-2020

The periodic system contains 118 chemical elements. However, only a few of them, such as hydrogen, carbon, nitrogen, oxygen and silicon, are of major importance in our daily lives. But things become really exciting from a chemical point of view when less well-known elements are involved. An ...

Unraveling the optical parameters: New method to optimize plasmon enhanced spectroscopy

23-Mar-2020

For exploring the nanoscale far beyond the optical resolution limit, tip-enhanced Raman spectroscopy (TERS) is widely recognized as an essential yet still emergent technique. Using this marker-free spectroscopic method scientists gain insights into the structural and chemical composition of ...

Fungus produces highly effective surfactant

26-Jun-2019

Mortierella alpina lives in the soil and likes to keep cool. This fungus, which belongs to the zygomycetes, grows best at temperatures of 10 to 15°C and occurs mainly in alpine or arctic habitats. In biotechnology, the fungus has been used for the large-scale production of polyunsaturated fatty ...

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 ...
