Hyperspectral imaging (HSI) is a state-of-the-art imaging technique useful for determining the composition of a variety of objects. Specifically, over-thousand-nanometer (OTN) HSI is particularly useful for detecting organic substances and in medical imaging. In a new study, researchers have developed the world’s first rigid endoscope for visible-to-OTN HSI, utilizing supercontinuum lighting and an acoustic-opto tunable filter. This innovative system can pave the way for advanced medical imaging, helping both physicians and patients.
Samples reveal evidence of changes experienced by the surface of asteroid Ryugu, some probably due to micrometeoroid bombardment.
Researchers Kazuaki Takasan and Kyogo Kawaguchi of the University of Tokyo with Kyosuke Adachi of RIKEN, Japan's largest comprehensive research institution, have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing. The findings were published in the journal Physical Review Research.
Cobalt-substituted BiFeO3 nanodots, engineered by Tokyo Tech researchers, demonstrate magnetoelectric-coupled ferroelectric and ferromagnetic single domain, offering significant promise for the advancement of low-power, nonvolatile magnetic memory devices. This innovation opens avenues for memory technologies where data can be written and read via electric and magnetic fields, respectively, thereby enhancing energy efficiency. This breakthrough can lead to the development of more energy-efficient memory technologies to meet the demands of modern electronic applications.
