The movement of molecules across membranes is discussed in terms of thermal fluctuations in the hydrocarbon chains of the membrane lipids. The thermal motion of the hydrocarbon chains results in the formation of conformational isomers, so-called kink-isomers of the hydrocarbon chains. "Kinks" may be...
There is power in numbers when generating electricity from the movement of molecules. Wave energy technology is a proven source of power generation, but there is power inherent in every molecule of liquid on earth, even when the liquid is at rest. At the molecular scale, atoms and ions are ...

Movement of molecules from blood to parenchyma of neural tissues is strictly restricted by the blood–brain barrier function of neural vasculature. Multicellular organisms have acquired this vascular barrier function to maintain the optimal microenvironment of neural tissues in which neural cells can functi...
The movement of solutes into plants can and should be expressed in terms of the specific free energies of the solute molecules. Similar expressions have been developed for the flow of water. The mathematical relation between the specific free energies of the solute and the water in solutions and...

1.A microscopic hairlike process extending from the surface of a cell or unicellular organism. Capable of rhythmical motion, it acts in unison with other such structures to bring about the movement of the cell or of the surrounding medium. ...
Cell function results from the interplay between the nanoscale organization of macromolecules and their dynamic behaviour. Yet understanding how they are linked has proven challenging due to the limitations of current microscopy techniques, which can only probe a few molecules at a time and which requi...
The movement of mice was recorded by an overhead camera. During the training process, the animal was introduced into one arm of the Y maze (start arm) and allowed to freely explore one of the other arms for 8 min (training arm). The behavior was analyzed by using EthoVision 11.5....
The movement of the nanoparticles through the thin film layer is caused by the strength of the heat flow and the stretching force of the sheet working together. The thermal thin-film flow and heat mechanism, and the properties of mass transfer along the film layer, were comprehensively ...
