Researchers have designed a new type of molecular motor. In contrast to previous designs, this molecule is symmetrical. It comprises two parts, which are connected by a central 'axle' and rotate in opposite directions, just like the wheels of a car.
By using the probe of an atomic force microscope to trigger a local chemical reaction, researchers showed that electrically conductive features as small as four nanometers can be patterned into individual graphene oxide sheets.
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.
