New Terahertz techniques help to detect striped superconductivity above the superconducting transition temperature in cuprates. Understanding high temperature superconductivity (high Tc) has been a long-standing challenge since its discovery in copper oxide compounds in 1986. A key issue in ...
First Characterization of a Sensory [FeFe] Hydrogenase
Hydrogenases are enzymes capable of making hydrogen gas (H2) using protons from water, a reaction with relevance to a potential future green energy economy based on H2. Bacteria containing these enzymes often produce H2 as a waste product during sugar metabolism in the absence of oxygen. ...
A decrease of agricultural ammonia emissions avoids mortality attributable to air pollution
Fine particulates have numerous sources – not only traffic, which is currently under particular scrutiny. Reducing agricultural emissions could also considerably reduce the particulate levels that are hazardous to health, concludes a study by researchers at the Max Planck Institute for Chemistry ...
Nanoparticles from the secretion of velvet worms form polymer fibres that can be recycled in water
Nature is an excellent teacher – even for material scientists. Researchers, including scientists at the Max Planck Institute of Colloids and Interfaces, have now observed a remarkable mechanism by which polymer materials are formed. In order to capture prey, velvet worms shoot out a sticky ...
Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a ...
New research published this week shows a rare state of matter in which electrons in a superconducting crystal organize collectively. The findings lay the groundwork for answering one of the most compelling questions in physics: How do correlated electron systems work, and are they related to one ...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of ...
Scientists reveal hidden magnetic order in one-dimensional quantum crystals doped with holes
Magnetism is a phenomenon that we experience in everyday-life quite often. The property, which is observed in materials such as such as iron, is caused by the alignment of electron spins. Even more interesting effects are expected in case that the magnetic crystals exhibit holes, i.e., lattice ...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the ...
Physicists observe novel quantum effect that limits the number of emitted photons
The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called Poisson-distribution. There are, however, light sources with non-classical photon number distributions that can only be described by the ...
