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...
We have studied the diffusion of the two organic molecules DC and HtBDC on the Cu(110) surface by scanning tunneling microscopy. Surprisingly, we find that long jumps, spanning multiple lattice spacings, play a dominating role in the diffusion of these molecules--the root-mean-square jump leng...
In recent years, there has been considerable progress in determining the soil properties that influence the structure of the soil microbiome. By contrast, the effects of microorganisms on their soil habitat have received less attention with most previous
The extraordinary success of mRNA vaccines against coronavirus disease 2019 (COVID-19) has renewed interest in mRNA as a means of delivering therapeutic proteins. Early clinical trials of mRNA therapeutics include studies of paracrine vascular endothelial growth factor (VEGF) mRNA for heart failure and...

Anne Devin, in Mitochondrial Physiology and Vegetal Molecules, 2021 4.1.1 TOM (translocase of outer mitochondrial membrane) complex The translocase of outer membrane represents the main entry gate for proteins bearing MTSs. Precursors of mitochondrial proteins are chaperoned by combinations of ...
The oil swelling was measured from visual inspection of photographs showing the surface movement of the oil meniscus in a column which was placed in a high-pressure cell with visualization windows. Furthermore, the equation of the gas diffusion coefficient was also formulated from the Stokes–...
● Movement of particles from an area of high concentration to an area of low concentration ● For this to work, particles must be able to move o Therefore, diffusion does not occur in solids, since the particles cannot move from place to place (only vibrate) ...
This framework’s surface and other relevant factors are closely associated with the diffusion of large molecules in confined spaces. Both experimental and computational perspectives have already investigated these aspects17,18. Zhao et al.19 inserted Fe3O4 magnetic particles into MOFs like UIO-66, ...
Mitochondrial energy conversion requires an intricate architecture of the inner mitochondrial membrane1. Here we show that a supercomplex containing all four respiratory chain components contributes to membrane curvature induction in ciliates. We report
