... Only one molecule - but four-wheel drive and no harmful emissions into the atmosphere.
 | In order to deliver cargo from point A to point B, you will need to do work. For this we use the mechanical energy of spinning wheels. To do this, we include the engine, which converts the energy stored in chemical bonds of hydrocarbons ( or the energy of an electric current ) into mechanical. So what happens in nature, for which there are so- called motor proteins that convert the ... Chemists and biochemists have many times appealed to these ... And one of the undoubted success in this direction - the recent work of Swiss researchers led by Karl-Heinz Ernst (Karl-Heinz Ernst) and their colleagues from the group of Professor Ben Feringa Netherlands (Ben Feringa) - created by them, ... The device consists of four independent rotating ... In fact, it is the smallest in the world of electric vehicle (compared to the authors, ... There are, however, the ... There is no reverse gear is not provided. In principle, everything is organized quite simply, some form of the molecule is placed on a conductive copper plate, and brought near to it the finest needle tunneling microscope. It is energized about 500 mV, and the electrons begin to flow from the needle on the molecule, and through it - on a substrate. This vyzyvet structural changes in all four ... The ... After the necessary calculations, scientists conducted a similar experiment in practice. Their ... The authors believe that this - only the first steps of the device, showing the possibility of designing molecules that convert electrical energy into mechanical work. Now they will be engaged in the creation of such a molecule, which could be activated by more convenient sources of energy - say, a laser beam. |
