simulations, a team led by Anton Tamtögl, from Graz University of Technology, unveiled the unique movement of triphenylphosphine (PPh 3 ) molecules on graphite surfaces, a behaviour akin to a nanoscopic ... reveals Anton Tamtögl, adding: “Measurements and simulation unveiled a sophisticated motion and ‘dance’ of the molecules, providing us with a ...

in this case). A remarkable aspect of this discovery is the direct transition between the two hybrid skyrmion phases, triggered by the variation of a magnetic field, and coinciding with a hexagonal-to-square ... vortex-like magnetic spin configurations, have emerged as a fascinating subject of study, capturing the attention of researchers ...

Illustration of polarization for (a) a ferromagnet, (b) an antiferromagnet, and (c) two magnon modes in a ferrimagnet. The “positive” polarization acoustic mode is a coherent right-handed circular precession ... memory storage density. Neutrons are a uniquely powerful probe for the advancement of these technologies due to the intrinsic spin of ...

transition from a linear to a circular economy is an integral aspect of transforming the EU into a sustainable, climate-neutral society. Through the circular concept of reduce-recover-recycle-reuse, a number of ... With exceptional porosity and a chemical versatility that enables their properties to be tuned to meet the requirements of a wide range ...

known as a spin liquid – by analogy with a liquid such as water in which the molecules move around randomly yet interact with near neighbours in a way that affects water’s overall properties. In a spin liquid ... quantum computing, tends to be rather fragile. However, a spin liquid could provide a form of entanglement robust to external ...

in surface pressure at a given area on the trough is generally assumed to be caused by the presence of a small amount of the drug at the surface,” explains Dr Richard Campbell, a Senior Lecturer in the ... technique. However, a simpler model than real cells is required for such studies. Lipids are the primary component of cell membranes, and lipid ...

topology – where the usual linear chain of monomer units forms instead a circular structure with the chain ends joined – is responsible for a range of unique physical and chemical properties: lower viscosities ... explains Matsarskaia. “This high efficiency means that a number of different experiments can be performed during the allocated beamtime, ...

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.
