Victor Lakhno, head of the Laboratory of Quantum-Mechanical Systems of the Institute of Mathematical Problems of Biology, RAS has calculated a critical temperature of the transition, energy, heat capacity and heat of transition of an ideal three-dimensional Bose-condensate of translation-invariant bipolarons (TI-bipolarons). The results obtained offer an explanation of the experiments with high-temperature superconductors.
A material with atomically thin layers of water holds promise for energy storage technologies, and researchers have now discovered that the water is performing a different role than anyone anticipated. The finding was possible due to a new atomic force microscopy method that measures the sub-nanoscale deformation rate in the material in response to changes in the material caused by energy storage.
Scientists say there was a significant release of radioactive particles during the Fukushima-Daiichi nuclear accident. The researchers identified the contamination using a new method and say if the particles are inhaled they could pose long-term health risks to humans.
By chemically attaching nano-particles of the rare earth element, gadolinium, to carbon nanotubes, the researchers have found that the electrical conductivity in the nanotubes can be increased by incorporating the spin properties of the gadolinium which arises from its magnetic nature.
Scientists at the University of Alberta have applied a machine learning technique using artificial intelligence to perfect and automate atomic-scale manufacturing, something which has never been done before. The vastly greener, faster, smaller technology enabled by this development greatly reduces impact on the climate while still satisfying the insatiable demands of the information age.
Researchers at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS) and the University of Cambridge engineered diamond strings that can be tuned to quiet a qubit's environment and improve memory from tens to several hundred nanoseconds, enough time to do many operations on a quantum chip.
In our bodies, the transfer of genetic information, viral infections and protein trafficking, as well as the synthesis and degradation of biomolecules are all phenomena that require the transport of molecules through channels. In a new study published in EPJ E, Manuela Pastoriza-Gallego from the University Paris-Seine, France, and colleagues have shown how to alter external factors such as external voltage to control the transport of a sample molecule through a test nanopore.
Physicists at Saarland University in Saarbrücken, Germany, have succeeded in entangling a single atom with a single photon in the telecom wavelength range. This constitutes a basic building block for transmission of quantum information over long distance with low loss. The results have raised great attention in the quantum technology community; now they are published in Nature Communications.
Scientists from the Singapore University of Technology and Design, together with collaborators from University Insubria (Italy) and Universidade Federal de Minas Gerais (Brazil) have shown that systems with strong interactions can rectify extremely well the flow of spins i.e. a spin current will flow much more in one direction than the other. This discovery could unlock new spintronics applications.
The vibrational motion of an atom in a crystal propagates to neighboring atoms, which leads to wavelike propagation of the vibrations throughout the crystal. The way in which these natural vibrations travel through the crystalline structure determine fundamental properties of the material. Now, researchers have shown that by swapping out just a small fraction of a material's atoms with atoms of a different element, they can control the speed and frequencies of these vibrations
