Nov 29, 2024 · In eastern China, a groundbreaking machine has just been unveiled. The CHIEF project aims to simulate extreme physical forces to explore natural phenomena that cannot otherwise be recreated. The facility, recently activated, is at the heart of a major scientific ambition. Developed by Zhejiang ...
Discovery: light transforms an insulator into a metal
An international team of scientists has discovered that strain waves generated by light pulses can transform an insulating material into a metal at an extremely rapid speed. This mechanism was observed in a thin film of vanadium oxide. Artistic depiction of …
This new type of engine pushes the boundaries of supersonic …
Dec 10, 2024 · An engine capable of transforming a shock wave into stable propulsion: this is the idea behind a recent technological breakthrough. In China, a team of researchers has developed a system that could redefine supersonic vehicles and the challenges related to their engines.
And here is a mechanical qubit! ️ - Techno-Science.net
A qubit is unique for its ability to exist in multiple states simultaneously. Here, researchers developed a membrane similar to a drumhead. This membrane can maintain information in three states: a stationary state, a vibrating state, or a superposition of both.
A promising breakthrough for the deployment of sodium-ion …
An international team of scientists, in collaboration with the company TIAMAT, recently published in the journal Nature Materials the discovery of a new compound with increased energy density within the NaSICON family. For this, they synthesized and chemically isolated previously unexplored phases with the general formula Na x V 2 (PO 4) 3, where x …
China plans to repurpose Starlink satellites to detect stealth …
Sep 23, 2024 · By altering the satellite signal, these planes could influence the quality of transmissions. The scientists tested this hypothesis with a commercial drone, the DJI Phantom 4 Pro, which simulates the radar footprint of a stealth aircraft.
Researchers observe quantum entanglement formation in real …
Electrons in atoms sometimes behave in surprising ways. Thanks to very precise simulations, researchers from the universities of Vienna and China managed to observe in detail how two electrons become quantumly entangled in just a few attoseconds (one attosecond is 1 x 10⁻¹⁸ seconds), an ultra-short time scale where entanglement between particles appears.
