Breakthrough in the Understanding of Quantum Turbulence

The researchers used a unique rotating cryostat in their study

Researchers have shown how energy disappears in quantum turbulence, paving the way for a better understanding of turbulence in scales ranging from the microscopic to the planetary.

Dr Samuli Autti from Lancaster University is one of the authors of a new study of quantum wave turbulence together with researchers at Aalto University.

The team’s findings, published in Nature Physics, demonstrate a new understanding of how wave-like motion transfers energy from macroscopic to microscopic length scales, and their results confirm a theoretical prediction about how the energy is dissipated at small scales.

Dr Autti said: “This discovery will become a cornerstone of the physics of large quantum systems.”

Quantum turbulence at large scales – such as turbulence around moving aeropla...

University of Sheffield researchers have developed a new ultrasound method that could help to more easily diagnose abnormal tissue, scarring and cancer. A new ultrasound method that can measure the level of tension in human tissue for the first time – a key indicator of disease – has been developed by researchers from the University of Sheffield.

The breakthrough, made by Dr Artur Gower from the University’s Department of Mechanical Engineering, together with researchers from Harvard, Tsinghua University, and the University of Galway, could be used to build new ultrasound machines that are able to better diagnose abnormal tissue, scarring, and cancer.

Ultrasounds use sound waves to create images of organs inside the human body...

Scientists Transform Algae into Unique Functional Perovskites with Tunable Properties

Calcitic shells of the dinoflagellate L. granifera. A) The calcitic shells of L. granifera exhibiting a porous ultrastructure. B) A single shell of L. granifera. C) Raman spectrum from a single shell confirming its calcitic nature. D) Electron back-scattering diffraction (EBSD) map and E) a corresponding (0001) pole figure of a single polished shell demonstrating that it consists of single crystalline domains where the c-axis of calcite is pointing radially from the center of the shell outwards. The colors in (E) correlate with similarly colored areas in (D). Scale bars: (A) 50 Âµm, (B) 5 Âµm and (D) is 5 Âµm.

Perovskites are materials that are increasingly popular for a wide range of applications because of their remarkable electrical, optical, and photonic properties...
