A research study led by Oxford University has developed a powerful new technique for finding the next generation of materials needed for large-scale, fault-tolerant quantum computing. This could end a decades-long search for inexpensive materials that can host unique quantum particles, ultimately facilitating mass production of quantum computers. The results have been published today (29 May) in the journal Science.
Inspired by the suckerfishes-shark motion behavior, they designed and prepared a kind of NIR light-propelled micro@nanomotor with weak acid-triggered release of H2O2-driven nanomotor. By the coordinated bond interaction, a large amount of Janus Au-Pt nanomotors with hydrogen peroxide (H2O2)-driven capacity, analogous to suckerfishes, were attached onto immovable yolk-shell structured polydopamine-mesoporous silica (PDA-MS) micromotor as the host to create two-stage PDA-MS@Au-Pt micro@nanomotor. PDA-MS@Au-Pt micro@nanomotor moved directionally by self-thermophoresis under the propulsion of NIR light with low power density. When the PDA-MS@Au-Pt entered into the weak acidic environment formed by a low concentration of H2O2, most small Au-Pt nanomotors were detached from the surface of PDA-MS due to the weak acidic sensitivity of the coordinated bond, and then performed self-diffusiophoresis in the environment containing a low concentration of H2O2 as a chemical fuel.
Earthquakes create ripple effects in Earth's upper atmosphere that can disrupt satellite communications and navigation systems we rely on. Nagoya University scientists and their collaborators have used Japan's extensive network of Global Navigation Satellite System (GNSS) receivers to create the first 3D images of atmospheric disturbances caused by the 2024 Noto Peninsula Earthquake. Their results show sound wave disturbance patterns in unique 3D detail and provide new insights into how earthquakes generate these waves. The results were published in the journal Earth, Planets and Space.
