The first example of an artificial molecular machine (AMM) was reported in 1994, featuring a rotaxane with a ring and two different possible binding sites. In 2016 the Nobel Prize in Chemistry was awarded to Jean-Pierre Sauvage, Sir J. Fraser Stoddart, and Bernard L. Feringa for the design and synthesis of molecular machines.
A photoswitch is a type of molecule that can change its structural geometry and chemical properties upon irradiation with electromagnetic radiation.Although often used interchangeably with the term molecular machine, a switch does not perform work upon a change in its shape whereas a machine does.

Synthetic molecular motors are molecular machines capable of continuous directional rotation under an energy input. [2] Although the term "molecular motor" has traditionally referred to a naturally occurring protein that induces motion (via protein dynamics ), some groups also use the term when referring to non-biological, non-peptide synthetic ...
On 20 December 2016, Feringa jointly received the Nobel Prize in Chemistry, together with Sir J. Fraser Stoddart and Jean-Pierre Sauvage, for their work on molecular machines. [1] Feringa had been considered a candidate for the Nobel Prize for some time, with The Simpsons including him in a list of candidates in 2010. [ 46 ]
Molecular motors are natural (biological) or artificial molecular machines that are the essential agents of movement in living organisms. In general terms, a motor is a device that consumes energy in one form and converts it into motion or mechanical work ; for example, many protein -based molecular motors harness the chemical free energy ...
On the molecular level, the interlocked molecules cannot be separated without the breaking of the covalent bonds that comprise the conjoined molecules; this is referred to as a mechanical bond. Examples of mechanically interlocked molecular architectures include catenanes, rotaxanes, molecular knots, and molecular Borromean rings.
Hydrogenation of ethene on a catalytic solid surface (1) Adsorption (2) Reaction (3) Desorption. Heterogeneous catalysis is catalysis where the phase of catalysts differs from that of the reagents or products. [1] The process contrasts with homogeneous catalysis where the reagents, products and catalyst exist in the same phase.
