Engineers dream that single-molecule-made motors can start molecular-level machine production. However, it is extremely difficult to build models based on larger engines alone. Now researchers from France and Ohio State University have collaborated on a new project and created the first molecular engine capable of rotating clockwise and counterclockwise. Christian Joachim, one of the lead authors of the project, said: "To create a working molecular engine must start from the basics and forget the macro-scale engine." This molecular engine is 1 nanometer high and 2 nanometers wide. The rotor contains five iron spokes, one of which is shorter than the others, and is easily noticeable when rotating. This molecular engine uses a quantum mechanical process called the inelastic electron tunneling effect. In this process, the electrons that are incident on the molecule lose part of their energy during the transfer process, and the resulting vibration will rotate the rotor. And their rotors can rotate even at minus 316 degrees Fahrenheit. A scanning tunnel microscope hovered above the molecular engine to test its performance by stimulating different parts of the molecular engine. The researchers found that they were able to control its rotation by focusing energy on different parts of the micro-engine. For example, targeting each longer spoke will cause a counterclockwise rotation, while using the shorter spoke will cause a clockwise rotation. Joachim said: "This engine is a molecular concept, and its goal is to improve our understanding of single-molecule rotation drive." Researchers are now focused on achieving two goals: First, connect this engine to the nano level The other gear is to install it on a nano-scale molecular car to provide energy for it.
