process has been a longstanding challenge. Fortunately, neutron diffraction provides valuable insights. As in X-ray diffraction, neutrons are reflected from a crystal structure to give a characteristic ... some of the highest quality cotton shirts or blouses have a soft silky sheen while also being hardwearing. This is because the cotton has ...

pressure inside the foam. Generally, a thin-film pressure balance is used to measure pressure on a single film and despite a similar foam preparation method, a difference of a factor of 10 has been observed ... sequentially, with each technique probing a different foam sample. The results obtained, however, are incomparable due to the unique nature ...

experiment, in which a particle is shot at a double slit in a wave-like manner, passes through both slits simultaneously as a wave and then superimposes on itself, so that afterwards a characteristic wave ... neutron interferometer from a silicon crystal and was able to observe the first interference of neutrons at the Vienna TRIGA reactor. A few ...

proteins, KaiA, KaiB, and KaiC assemble to form the KaiABC complex. Cryogenic electron microscopy studies can identify most of the structure of this complex, but the KaiA protomers seem to be a bit too shy ... despite large fluctuations in the KaiA N-terminal domains, their preferential positionings mask the hydrophobic surface of the KaiA ...

alone. A complete hydrogen-bond network could be observed between the protein and its ligand. A low-barrier hydrogen bond was also identified ‑ a special type of strong hydrogen bond which plays a role in ... Nature Communications. Antibiotic resistance is a rapidly increasing global threat to human health. The World Health Organization has ...

achieved by a number of ways that grows exponentially with the number of tetrahedra. In this context, the possibility of a quantum variant of spin ice has aroused a lot of attention. Such a state of matter ... Credit: Nicolas Gauthier May 2020 Spin ice is a recently discovered state of matter, made of a macroscopic landscape of degenerate magnetic ...

graphite. Typically, diffusion, the speed of a particle’s movement on a surface, is a thermally activated process. The higher the temperature, the faster a particle is able to move. At lower temperatures ... movement of a liquid, and there was very little change in its diffusion rate from high to low temperatures, compared to the sample and other ...

describe the internal structure of a magnetic nanoparticle using a simple, static model. According to this model, magnetic nanoparticles are composed of a magnetic core and a surface that is not – or only slightly ... nanoparticles consist of a magnetic material containing, for example, iron, nickel, or cobalt. If the particles are small enough, ...

mechanical workshop with a wire spark erosion machine. Anode wires are inserted along the centre of the cathode trenches with a precision of 50 micrometres, using a metrology system based on a numerical microscope ... anode wires are run through the cathode trenches at a pitch of 2.5 mm using ceramic combs (right) In order to dispose of a spare ...

layer by layer, a process that often requires multiple steps. A team of our scientists at the Institut Laue–Langevin (ILL) and the Technical University of Berlin (TUB) has developed a one-step procedure ... cost-effective. First, two components are mixed together – a polysaccharide, simple chains of sugar molecules bonded together, and a fatty ...
