Research team decodes symbiotic interactions in marine algae using raman spectroscopy

Implications for biotechnology and environmental protection

02-Oct-2024 - In a recent study, researchers from the Leibniz Institute of Photonic Technology (Leibniz IPHT) and the Friedrich Schiller University Jena have shown how they can non-invasively and non-destructively investigate the growth and interactions of the green alga Ulva and its bacterial community using ...

Molecular dynamics in real time

A novel spectroscopic method allows ultrafast processes within molecules to be observed

08-May-2024 - A European research team has developed a novel spectroscopic method that can be used to observe ultrafast dynamic processes of electrons and vibrations within molecules – with atomic resolution and in real time. A team from the University of Jena supported the experimental team in Barcelona in ...

Artificial intelligence for better diagnostics

Standardized methods facilitate the evaluation of Raman spectra

15-Dec-2021 - Light-based methods are increasingly used for analytical problems in the fields of health, environment, medicine and safety. Raman spectroscopy is a suitable method in this context. The measurement data collected in this process are complex and extensive molecular fingerprints. Artificial ...

Bacterial toxin blinds algae

Chemical “fingerprints” reveal the “murder weapon”

18-Aug-2021 - University of Jena researchers have discovered a bacterial toxin that destroys the colour pigments in the eyespot of the single-cell green alga Chlamydomonas reinhardtii. Together with another toxic substance, the bacteria of the species Pseudomonas protegens not only disorientate and immobilise ...

Making the invisible visible

New method for studying atomic structures in material surfaces

21-May-2021 - Researchers from Friedrich Schiller University Jena, the University of California Berkeley and the Institut Polytechnique de Paris use intense laser light in the extreme ultraviolet spectrum to generate a non-linear optical process on a laboratory scale – a process which until now has only been ...

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 ...

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 ...

How the first step affects the (watery) result

German Scientists from Jena and Erlangen-Nürnberg show the way to a more effective creation of hydrogen

28-Jun-2010 - Energy from hydrogen - scientists from all over the world work on this solution to overcome the energy crisis. Amongst other things they try to use the sunlight as driving force for the splitting of water into hydrogen and oxygen. In trying to copy the photosynthesis in the laboratory a team of ...
