On the way to printable organic light emitting diodes
12-Jul-2019
Organic light-emitting diodes (OLEDs) are used today in many electronic devices for display applications, ranging from smartphones to televisions. Scientists at the Max Planck Institute for Polymer Research (MPI-P) have now succeeded in developing a new design for these LEDs. They have been able ...
In the active centre of carbon dioxide conversion
Scientists reveal the features of efficient carboxylase enzymes
12-Jul-2019
In order to overcome the climate crisis, two measures are required: The reduction of carbon dioxide (CO2) emissions, and removal of CO2 from the earth atmosphere. The latter is the goal of Tobias Erb's research group at the Max Planck Institute for Terrestrial Microbiology in Marburg. Their ...
How living matter self-organizes through chemical signals
Scientists show new mechanism of self-organization of living matter
08-Jul-2019
Cells and microorganisms produce and consume all sorts of chemicals, from nutrients to signaling molecules. The same happens at the nanoscale inside cells themselves, where enzymes catalyze the production and consumption of the chemicals needed for life. In new work published in Physical Review ...
Novel approach to self-assembling mobile micromachines
27-Jun-2019
Building a robot with many different components is a challenging task, even more so at the micro scale. Very convenient, if the parts self-assemble. The self-assembly of particles is nothing new. In fact, it has been achieved for decades. Magnetic particles interacting under rotating magnetic ...
Laser flashes for polarized electron and positron beams
14-Jun-2019
Simulations show new methods for efficient polarization: Physicists from the Max Planck Institute for Nuclear Physics in Heidelberg proposed novel methods for generation of relativistic spin polarized electron and positron beams. Using extensive simulations, they found three different scenarios ...
Direct Observation of Giant Molecules
Physicists achieved to form giant diatomic molecules and optically detect them afterwards by using a high-resolution objective
07-Jun-2019
The tiny size of conventional diatomic molecules in the sub-nanometer regime hinders direct optical resolution of their constituents. Physicists from the Quantum Many Body Division at MPQ led by Prof. Immanuel Bloch were able to bind pairs of highly excited atoms at a distance of one micrometer. ...
Simulating nature’s cosmic laboratory, one helium droplet at a time
27-Mar-2019
Two astronomers from the Max Planck Institute for Astronomy and from the University of Jena have found an elegant new method to measure the energy of simple chemical reactions, under similar conditions as those encountered by atoms and molecules in the early solar system. Their method promises ...
Turning a molecule into a coherent two-level quantum system
08-Mar-2019
Organic dye molecules are commonly known from color pigments or from fluorescence microscopy in biology. Although as any other molecule, they are fundamentally quantum mechanical objects made of a small number of atoms, they are usually not associated with quantum technologies, not even within ...
New material for chemistry text books
Calcium carbonate forms a previously unknown aqueous crystal structure
06-Mar-2019
Even the well-known can sometimes surprise. Calcium carbonate (CaCO3), also known colloquially as lime or chalk, is a mineral that has already been thoroughly analysed by chemists. But chemistry books, in which it is listed as occurring in five different crystal structures, now need to be ...
Three-dimensional structure of skyrmions becomes visible for the first time
05-Mar-2019
Skyrmions are three-dimensional structures that occur in magnetic materials. They are magnetic vortices a few nanometers in size in which atomic elementary magnets are arranged in closed vortex structures. Skyrmions are topologically protected, meaning that their shape cannot be changed. First ...
