Physicists from Lancaster University have established why objects moving through superfluid helium-3 lack a speed limit; exotic particles that stick to all surfaces in the superfluid. The discovery may guide applications in quantum technology, even quantum computing, where multiple research groups already aim to make use of these unusual particles.
Colloidal particles have become increasingly important for research as vehicles of biochemical agents. In future, it will be possible to study their behaviour much more efficiently than before by placing them on a magnetised chip. A research team from the University of Bayreuth has discovered that colloidal rods can be moved on a chip quickly, precisely, and in different directions. A pre-programmed magnetic field even enables these controlled movements to occur simultaneously.
Using the X-ray laser European XFEL, a research team has investigated how water heats up under extreme conditions. In the process, the scientists were able to observe water that remained liquid even at temperatures of more than 170 degrees Celsius. The investigation revealed an anomalous dynamic behaviour of water, which is of fundamental importance for investigations of sensitive samples using X-ray lasers, as the scientists report in the Proceedings of the National Academy of Sciences.
A research team led by the University of Tsukuba investigated the acoustic properties of disordered lysozyme proteins by using terahertz spectroscopy. They found that the fractal nature of the proteins is responsible for its unusually large vibrations at low frequencies, which may lead to a better theory for disordered materials.
Imagine harnessing evaporation as a source of energy or developing next generation actuators and artificial muscles for a broad array of applications. These are the new possibilities with the creation by an international team of researchers, led by The City College of New York's Xi Chen and his co-authors at the CUNY Advanced Science Research Center, of shape-changing crystals that enable energy transfer from evaporation to mechanical motion.
In a new study appearing in the journal Physical Review Letters, researchers describe a technique for using LEGO®-like elements at the scale of a few billionths of a meter. Further, they are able to cajole these design elements to self-assemble, with each LEGO® piece identifying its proper mate and linking up in a precise sequence to complete the desired nanostructure.
Researchers at Chalmers University of Technology, Sweden, together with colleagues from other universities, have discovered the possibility to prepare one-atom thin platinum for use as a chemical sensor. The results were recently published in the scientific journal Advanced Material Interfaces.
Researchers have used a combination of AI and quantum mechanics to reveal how hydrogen gradually turns into a metal inside giant planets.
Imaging artifacts discovered in high-resolution electron microscopes may impact development of next-generation electronic devices.
Rice University researchers show how thermoelectricity hurdles some defects, but not others, in gold nanowires. The discovery has implications for making better thin-film electronic devices.
