Motor And Energy Store In One

Physicists reinvent the wheel with the help of a polymer fibre


Physicists and material scientists have succeeded in constructing a motor and an energy storage device from one single component. They used an elastic polymer fibre closed into a ring that was made to rotate on application of an external energy supply. The researchers from the universities in ...


Exploring the phenomenon of superconductivity

Fermions in flatland pair up at very high temperatures: Physicists find evidence of an exotic state of matter


Using ultracold atoms, researchers at Heidelberg University have found an exotic state of matter where the constituent particles pair up when limited to two dimensions. The findings from the field of quantum physics may hold important clues to intriguing phenomena of ...


Mechanism for radiation damage identified

Scientists examine electronic decay processes with the aid of quantum chemistry


What exactly are the processes when x-ray photons damage biomolecules with a metal centre? This question has been investigated by a team of scientists at the Institute for Physical Chemistry of Heidelberg University. Using the methods of quantum chemistry, they examined the underlying electronic ...


Einstein’s Theory of Relativity explains fundamental properties of gold

Properties of the coinage metal elements are already predetermined in their atoms.


Some fundamental properties of the coinage metal elements gold, silver and copper, such as chemical behaviour or colours, are already predetermined in their atoms. The unique properties of gold can be largely explained by Albert Einstein’s theory of relativity. Chemists from Heidelberg University ...


Quantum physics: hot and cold at the same time

Cloud of quantum particles can have several temperatures at once


Temperature is a very useful physical quantity. It allows us to make a simple statistical statement about the energy of particles swirling around on complicated paths without having to know the specific details of the system. Scientists from the Vienna University of Technology together with ...


Partners sign new agreement for joint catalysis laboratory in Heidelberg

BASF and Heidelberg University renew their research cooperation up to the end of 2017


BASF and Heidelberg University have signed a new agreement for their joint catalysis laboratory “Catalysis Research Laboratory” (CaRLa). The research cooperation at Heidelberg site ongoing since 2006 has been extended to October 2017. “Catalysts play a central role in many technical processes in ...

Help in the Search for the Needle in the Haystack

Physicists render usable method for detecting extremely rare inert gas isotopes for water dating


In the earth and environmental sciences, radioactive isotopes, atom variants that decay over time, play a major role in age determination. A radioactive isotope of the inert gas argon (39Ar), for example, is used to determine the age of water or ice. Such isotopes are extremely rare, however – ...

Highly Reactive Gold Carbene Complex Shines in Emerald Green

Heidelberg chemists succeed in isolating carbon-gold compound of “amazing stability”


With a chemical “trick”, scientists at Heidelberg University have succeeded in isolating a stable gold carbene complex. Chemist Prof. Dr. Bernd F. Straub and his team are the first to have created the basis for directly examining the otherwise unstable gold-carbon double bond. Prof. Straub ...


Fluorescence spectroscopy using a smartphone


Scientists in Germany have used digital photographs to extract colour and spectral information of reactive fluorophores. They studied the optical properties of different pyridine-substituted cross-conjugated fluorophores (XF). Upon protonation of the pyridine nitrogen, the colour changes of XFs ...

An Impossible Star

Astronomers observe a 13-billion-year-old star with an unusual chemical composition


A team of European astronomers led by a scientist of Heidelberg University has discovered a star that according to standard astronomical thinking should not be able to exist: it is made up almost entirely of hydrogen and helium with only minute traces of other elements. In terms of the generally ...
