• pharmaceutical production without solvents and CO₂ emissions
  The Bundesanstalt für Materialforschung und -prüfung (BAM) is developing a more sustainable process to produce active pharmaceutical ingredients in a major EU project: The pilot project is intended...
• Intense light pulses in the mid-infrared for spectroscopic and technical applications
  A new light source generates ultrashort infrared pulses at wavelengths around 12 µm with previously unattained peak intensity and stability. First experiments in vibrational spectroscopy on water d...
• Spin correlation between paired electrons demonstrated
  Physicists at the University of Basel have experimentally demonstrated for the first time that there is a negative correlation between the two spins of an entangled pair of electrons from a superco...
• New model describes boiling process with much greater precision
  When a liquid boils in a vessel, tiny vapor bubbles form at the bottom and rise, transferring heat in the process. How these small bubbles grow and eventually detach was previously not known in any...
• How photoelectrodes change in contact with water
  Photoelectrodes based on BiVO₄ are considered top candidates for solar hydrogen production. But what exactly happens when they come into contact with water molecules? A study in the Journal of t...
• Breakthrough in "meta-C-H functionalization" of pyridines
  In chemicals used in agriculture, as well as in pharmaceuticals and a variety of materials, pyridines are often found as so-called functional units which decisively determine the chemical propertie...
• A chip to replace animal testing
  Empa researchers are developing a medical chip in collaboration with the ETH Zurich and the Cantonal Hospital of St.Gallen that will allow statements to be made about the effect of substances on ba...
• A novel concept for photovoltaics
  The group of Prof. Yana Vaynzof at the Integrated Center for Physics and Photonic Materials (IAPP) and the Center for Advancing Electronics Dresden (cfaed) at Technische Universität Dresden has dem...
• How bacteria gain energy through CO₂ fixation
  Acetic acid-producing bacteria (acetogens) are very interesting for the biotech industry: They fix the climate gas CO₂ and at the same time produce not only acetic acid, but also substances such as...
• New aspects of surface wetting revealed
  When a surface is getting wet, also the composition of the liquid plays a role in the wetting process. Researchers from the Max Planck Institute for Dynamics and Self-Organization (MPI-DS) found th...
• Mini-sensors against the overfertilisation of soils
  According to a report by the EU Commission, over 60 percent of agricultural soils in the European Union are overfertilised. The consequences are soil acidification, polluted waters, reduced biodive...
• Multiplex analysis with paramagnetic microparticles
  Among many challenges, the COVID-19 pandemic also brought a surge of innovation in diagnostics. Within the shortest amount of time, reliable detection methods had to be developed, countless laborat...
• Copper a clue in the fight against cancer
  For cancer cells to grow and spread around the human body, they need proteins that bind copper ions. New research about how cancer-related proteins bind the metal and how they interact with other p...
• New material will make locally flexible diodes possible
  Diodes allow directed flows of current. Without them, modern electronics would be inconceivable. Until now, they had to be made out of two materials with different characteristics. A research team ...
• How microorganisms of karst ecosystems resist human intervention
  RUDN University soil scientist for the first time investigated how soil microorganisms resist changes due to human agricultural activities in karst regions. Soil bacteria have a significant impa...
• Batteries without critical raw materials
  The market for rechargeable batteries is growing rapidly, but the necessary raw materials are limited. Sodium-ion batteries, for example, could offer an alternative. A joint research group from HZB...
• Coffee could offer protection from catching COVID-19
  Professor Nikolai Kuhnert and his team from Jacobs University were able to show that a compound in coffee inhibits the interaction between the spike protein of the coronavirus and the ACE-2 Recepto...
• Sustainable recycling using electrochemistry
  New Halocycles project aims to develop a halogen recovery technique contributing to the stabilization of the power grid and the defossilization of the future industrial society. Increasing the r...
• Holographic microscopy provides insights into the life of microplankton
  Using holograms created in digital microscopes and interpreted using artificial intelligence (AI), for the first time researchers can now follow the lives of microplankton at the individual level. ...
• Unique database for the cultivation of microorganisms
  Researchers at the Leibniz Institute DSMZ-German Collection of Microorganisms and Cell Cultures GmbH in Braunschweig, Germany have published a freely accessible database for growth media of microor...
• Ecosystems more sensitive to nitrogen pollution than previously assumed
  The report (Review and revision of empirical critical loads of nitrogen for Europe) provides revised and updated empirical threshold values (critical loads) for harmful nitrogen inputs to natural e...
• Precisely focused light thanks to 3D printing
  An interdisciplinary team of researchers from Korea, Australia, Great Britain, and Germany - with participation of Leibniz Institute of Photonic Technology (Leibniz IPHT) - were able for the first ...
