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 motors.
This motor is driven by the flow of protons across a membrane, possibly using a similar mechanism to that found in the F o motor in ATP synthase. Molecular dynamics simulation of a synthetic molecular motor composed of three molecules in a nanopore (outer diameter 6.7 nm) at 250 K.

The single-molecule electric motor is an electrically operated synthetic molecular motor made from a single butyl methyl sulphide molecule. [1] The molecule is adsorbed onto a copper (111) single-crystal piece by chemisorption. [1]
Unlike a molecular motor, any mechanical work done due to the motion in a switch is generally undone once the molecule returns to its original state unless it is part of a larger motor-like system. The image on the right shows a hydrazone -based switch that switches in response to pH changes.
The term "Brownian motor" was originally invented by Swiss theoretical physicist Peter Hänggi in 1995. [3] The Brownian motor, like the phenomenon of Brownian motion that underpinned its underlying theory, was also named after 19th century Scottish botanist Robert Brown, who, while looking through a microscope at pollen of the plant Clarkia pulchella immersed in water, famously described the ...

However, a great deal of current experimental work is devoted to synthetic systems such as artificial self-propelled particles. [ 8 ] [ 9 ] [ 10 ] Active matter is a relatively new material classification in soft matter : the most extensively studied model, the Vicsek model , dates from 1995.
The California DMV apologized for a license plate appearing to mock the Oct. 7 attacks on Israel. The car owner's son said it was being misinterpreted.
