Resonators are an important tool in physics. The curved mirrors inside the resonators usually focus light waves that act, for instance, on atoms. Physicists have now managed to build a resonator for electrons and to direct the standing waves thus created onto an artificial atom.
So-called Froehlich condensation, a state in which protein molecules' vibrational modes coalesce at the lowest frequency, was first predicted almost five decades ago, but never experimentally demonstrated until now.
In addition to utilizing food and beverage waste that would otherwise decompose and be of no use, this development can also reduce potentially harmful waste from LEDs generally made from toxic elements.
Studying catalytic processes on one single nanoparticle at a time, instead of on several billion simultaneously as has previously been the case, will create unique and more in-depth understanding of catalytic reactions on nanoparticles than previously possible - and it will at the same time lay the foundation for a new and sustainable energy technology and chemical synthesis.
Researchers will take on a task that until now has been deemed impossible: creating strong interaction between light and magnetic fields and determining ways to control light with magnetism on the nanoscale.
Magnets are well-known from the physics lessons at school, but they are hardly covered in chemistry lectures; and it is still a chemical process by means of which researchers have succeeded in controlling magnetic properties in bulk ferromagnets.
Researchers have developed a dielectric film that has optical and electrical properties similar to air, but is strong enough to be incorporated into electronic and photonic devices - making them both more efficient and more mechanically stable.
Scientists have developed a new way to store information that uses ions to save data and electrons to read data. This could enable the size of storage cells to be reduced to atomic dimensions. But that is not the only advantage of the new technology, as the researchers report.
