In humans an excess of uric acid (or hyperuricemia) is associated with, or responsible for several serious health problems: metabolic syndrome 1, gout and kidney dysfunction. Other living beings are (...)

In Paris, October 1, 2013, groups from the “Chimie-Physique Matière et Rayonnement” Laboratory (UPMC-CNRS), together with SOLEIL Synchrotron, the University of Trieste (Italy) and Uppsala University (...)

Dissociation is one of the simplest chemical reactions, where a molecule breaks apart into two or more fragments, i.e., other molecules, atoms, ions, or radicals. Understanding the mechanisms of (...)

The energy crisis driven by the long-term petroleum shortage, the growing demand for cleaner fuels and a more rational utilisation of resources (coal, natural gas, biomass…) are among the main reasons (...)

Supported molybdenum catalysts are widely used in their sulfide state in the treatment petroleum fractions, which are important economic and environmental issues. In their oxide states they can be (...)

Ferroelectric memory devices could be an alternative to magnetic based memories for future high-density data storage. Such devices have considerable advantages: they are non-volatile, have fast read (...)

In 2008, a new family of superconductors was discovered, based on square planar iron. This attracted the attention of many physicists because superconductivity was found to occur up to relatively high (...)

Selenides e.g. bulk silver selenide are of much interest because of their use in various applications such as a thermoelectric materials, a photosensitizer in photography, in photochargeable batteries (...)

Experiments performed at DEIMOS beamline by a team of researchers of the Italian National Research Councils (CNR), the University of Manchester and French CNRS found that a single molecule may well (...)

Iron-sulfur clusters are ubiquitous cofactors made of iron and inorganic sulfur. They are essential for the function of proteins involved in a great range of activities: electron transport in (...)

Legionella pneumophila, which causes the Legionnaire’s disease, escapes destruction by the immune system by hiding inside the infected cell. This camouflage strategy requires that the bacterium (...)

Researchers at the Paris NanoSciences Institute (CNRS-UPMC), in collaboration with groups at SOLEIL and UVSQ, have developed a new technique for growing epitaxial alloy nanowire arrays in a matrix (...)
