When rocks lay the groundwork for the origin of life

Mineral catalysts found in deep-sea vents convert CO2 and H2 to biomolecules, showing striking parallels to known biological pathways

An international collaboration of researchers in Germany, France and Japan investigated the catalytic activities of minerals found in deep-sea hydrothermal vents. The results suggest that mineral-driven chemical reactions might be closely mapped onto microbial carbon metabolism. … Continue Reading ››

Graphene as a detective to unravel molecular self-assembly

Researchers from the University of Strasbourg & CNRS (France), in collaboration with Humboldt University of Berlin and DWI – Leibniz Institute for Interactive Materials/RWTH Aachen University (Germany), have demonstrated that graphene devices can be used to monitor in real time the dynamics of molecular self-assembly at the solid/liquid interface. Their results have been published in Nature Communications.

Un réseau précurseur de la biochimie du vivant identifié

Pour progresser dans la compréhension de l’origine de la vie, des chercheurs de l’Institut de science et d’ingénierie supramoléculaires (ISIS - CNRS/Université de Strasbourg) ont imaginé un réseau dynamique de réactions chimiques, proche de la biochimie actuelle du vivant. À partir de deux biomolécules « simples » dissoutes dans une eau riche en fer, et en seulement quelques heures, les chercheurs sont … Continue Reading ››

Mirrors change chemical selectivity

A chemical reaction transforms the molecules that make up matter. To influence chemical reactions, chemists typically act on the molecules themselves, rather than the space in which the reaction takes places. However, researchers at the University of Strasbourg have shown that chemical reactions can indeed be influenced simply by conducting them between two appropriately spaced mirrors, kept only micrometers … Continue Reading ››

Enlightening full-color displays

Researchers from the University of Strasbourg & CNRS (France), in collaboration with University College London (United Kingdom), and Humboldt University Berlin (Germany), have shown that a subtle combination of light-emitting semiconducting polymers and small photoswitchable molecules can be used to fabricate light-emitting organic transistors operating under optical remote control, paving the way to the next … Continue Reading ››

Oscillating artificial microtubules

Oscillating artificial microtubules

Chemically fuelled processes control size oscillations of natural fibres inside the body such as microtubules or actin filaments. Researchers from the University of Strasbourg have now discovered similar size oscillations in a completely artificial system. Brightly coloured molecules form extended supramolecular fibres that can be controlled by redox chemistry. In a … Continue Reading ››
