The article reflects aspects of content and appraisals of awarding the Nobel Prize 2016 in science of researchers J.-P. Sauvage, J. F. Stoddart and B. L. Feringa for ”Design and synthesis of molecular machines”. By three outstanding inventions (three steps) the Nobel Prize winners managed to revolutionize the machines’ synthesis at molecular level, and obtained machines which are a million times smaller than a millimeter, or a thousand times smaller than a human hair. Applications of molecular machines, in general, and molecular mechanical transmissions and engines, in particular, will revolutionize the fields of information technology, computers with molecular nano chips, nano systems for energy storage, nano-robots, medicine, etc. The article describes the exceptional advantages of precessional transmissions in the development of molecular transmissions. The paper presents constructive-kinematic peculiarities of molecular precessional transmissions developed at the Technical University of Moldova (TUM). Also molecular precessional motor is presented which was elaborated in 2011 at TUM, based on another functional principle of converting chemical energy into mechanical energy with controllable motions which is different from the one proposed in 1999 by B. L. Feringa and achieved in 2009 by C. Joachim – considered the first in the world who managed to rotate a molecular wheel. |
