Tsukuba University scientists create movies of the ultrafast motion of electrons traveling through an organic semiconductor with atomic-level resolution. This work may lead to more powerful and miniaturized smart devices.
A research team from the Institut national de la recherche scientifique (INRS) has joined forces with French researchers from the The Institute of Chemistry and Processes for Energy, Environment and Health (ICPEES), a CNRS-University of Strasbourg joint research lab, to pave the way towards the production of green hydrogen.
An MIT-led search for axions from nearby star Betelgeuse has come up empty, significantly narrowing the search for hypothetical dark matter particle.
Hard X-ray free-electron lasers (XFELs) have delivered intense, ultrashort X-ray pulses for over a decade. One of the most promising applications of XFELs is in biology, where researchers can capture images down to the atomic scale even before the radiation damage destroys the sample. In physics and chemistry, these X-rays can also shed light on the fastest processes occurring in nature with a shutter speed lasting only one femtosecond - equivalent to a millionth of a billionth of a second.
Marking a major achievement in the field of spintronics, researchers at Brookhaven National Laboratory and Yale University have demonstrated the ability to control spin dynamics in magnetic materials by altering their thickness. The study, published today in Nature Materials, could lead to smaller, more energy-efficient electronic devices.
After five years of work, ENSURE, an ERC H2020 project (Grant Agreement 647554) developed at Politecnico di Milano, has achieved its main goal: to control and optimise an unconventional technique of particle acceleration by irradiating nanostructured materials with innovative properties using super-intense and ultra-short laser pulses. The project's conclusion was crowned by the publication of the article "Integrated quantitative PIXE analysis and EDX spectroscopy using a laser-driven particle source" in Science Advances, due out on Friday 15 January 2021.
Scientists are able to selectively knockout nucleons and preformed nuclear clusters from atomic nuclei using high-energy proton beams. In an experiment the existence of preformed helium nuclei at the surface of several tin isotopes could be identified in a reaction. The results confirm a theory, which predicts the formation of helium clusters in low-density nuclear matter and at the surface of heavy nuclei.
Tsukuba University scientists describe the diffusion of sound in disordered materials, such as glass, using a new mathematical model. This work may lead to stronger and cheaper displays for touchscreen devices.
A breakthrough that has implications for molecular biology, pharmacology and nanotechnologies. The fields of application are many. Identifying the mechanisms behind neurodegenerative processes in some proteins, for example, can help limit their proliferation. Understanding how a protein takes on a certain shape can open the way to use the nanomachines that nature has designed to cut, edit or block damaged or defective genes. Their study was published in the international academic journal Physical Review Letters
Novel calculations have enabled the study of nearly 700 isotopes between helium and iron, showing which nuclei can exist and which cannot. In an article published in Physical Review Letters, scientists from TU Darmstadt, the University of Washington, the Canadian laboratory TRIUMF, and the University of Mainz report how they simulated for the first time using innovative theoretical methods a large region of the chart of nuclides based on the theory of the strong interaction.
