• More sustainability with Mechanochemistry
  Flour, coffee or spices: Many people know the principle of a mill from the kitchen. But special mills are also used for research purposes in the laboratories of the Max-Planck-Institut für Kohlenfo...
• Water in the Earth's Interior? - Diamond from a depth of 660 kilometers analyzed spectroscopically
  The transition zone between the Earth's upper and lower mantle contains considerable quantities of water, according to an international study involving the Institute for Geosciences at Goethe Unive...
• Polymers Films with up to 99.99% antibacterial efficiency
  RUDN University chemist with his colleagues from Portugal has developed two types of coating based on new coordination polymers with silver. Both compounds were successfully tested against four com...
• How Escherichia coli Cells evade antibacterial treatment
  The formation of persisters is an important feature of bacteria like Escherichia coli (E. coli). These noxious cells, being able to go dormant, are highly resistant to antimicrobial treatments and ...
• Making molecular vibrations more detectable
  In molecules, the atoms vibrate with characteristic patterns and frequencies. Vibrations are therefore an important tool for studying molecules and molecular processes such as chemical reactions. A...
• New Oxidation State of Rhodium
  Mayara da Silva Santos, doctoral candidate at the University of Freiburg's Institute of Physics, has discovered a new oxidation state of rhodium. This chemical element is one of the most catalytica...
• Superheavy element Flerovium is a volatile metal
  An international research team has succeeded in gaining new insights into the chemical properties of the superheavy element Flerovium - element 114 - at the accelerator facilities of the GSI Helmho...
• Exploring technetium in the environment
  With a half-life of about 210.000 years, the radioactive isotope technetium-99 (⁹⁹Tc), which is produced in nuclear reactors by fission of the urani_{um is}otope ²³⁵U, plays a central role in the ques...
• Super-dense packing of hydrogen molecules on a surface
  In a paper in Nature Chemistry, scientists from the Max Planck Institute for Intelligent Systems, the Technische Universität Dresden, the Friedrich-Alexander-Universität Erlangen-Nürnberg, and Oak ...
• Ammonia - a trump card for the energy transition process
  During his internship as a Chemical Technology student at Danish company Haldor Topsøe, UT PhD researcher Kevin Rouwenhorst realised the many opportunities offered by ammonia. At the moment, it is ...
• New variant of Hydroformylation discovered
  A team of researchers from Evonik and the Leibniz Institute for Catalysis (LIKAT) has once again achieved a breakthrough in the field of hydroformylation. Hydroformylation is one of the most import...
• Making and breaking of chemical bonds in single "nanoconfined" molecules
  Researchers around the world are working to develop efficient materials to convert CO₂ into usable chemical substances - work that is particularly pressing in view of global warming. A team from th...
• A new tool for Cryo-Electron Microscopy
  Researchers at Forschungszentrum Jülich and Heinrich Heine University Düsseldorf led by Prof. Dr. Carsten Sachse are using cryo-electron microscopy, or cryo-EM for short, to make biomolecules visib...
• New hope for reducing harm from Highly Hazardous Pesticides
  After more than two years without a face-to-face meeting, representatives from governments, the private sector, industry and civil society from around the world met in Bucharest from August 29 to S...
• How artificial intelligence can explain its decisions
  Today, when an algorithm identifies a tumour in a tissue sample, it doesn't reveal how it arrived at this result. And that's not very trustworthy. Researchers in Bochum are therefore pursuing a new...
• New reaction facilitates drug discovery
  Chemists at ETH Zurich have found a facile method that allows a commonly used building block to be directly converted into other types of important compounds. This expands the possibilities of chem...
• A new rule for orbital formation in chemical reactions
  Squeaky, cloudy or spherical - electron orbitals show where and how electrons move around atomic nuclei and molecules. In modern chemistry and physics, they have proven to be a useful model for qua...
• Recycling Greenhouse Gases
  CO₂ and methane can be turned into valuable products. But until now, the catalysts required for such reactions quickly lose their effectiveness. TU Wien has now developed more stable alternatives. ...
• Less risk, less costs: Portable spectroscopy devices could soon become real
  Nuclear magnetic resonance (NMR) is an analytical tool with a wide range of applications, including the magnetic resonance imaging that is used for diagnostic purposes in medicine. However, NMR oft...
• Rare insights into growing nanoparticles
  How exactly do nanoparticles form in solution? Researchers from Universität Hamburg and DESY have now been able to observe the growth of nanoparticles in solution in real time. In the journal Natur...
• Floating Nanoparticles: New mechanism discovered in light-induced binding
  Illuminated by a laser, nanoparticles are attracted to its light and float in space. This "optical tweezers" was awarded the Nobel Prize in Physics in 2018. Researchers at the University of Dui...
• Miniaturized Lab-on-a-Chip for real-time Chemical Analysis of Liquids
  A fingertip-sized chip replaces bulky laboratory equipment. An infrared sensor has been developed at TU Wien (Vienna) that analyses the content of liquids within the fraction of a second. In an...
