Van der Waals radius is the radius of an imaginary sphere surrounding an atom. It represents the distance of the closest approach for another atom. In other words, van der Waals radius is one half of the distance of separation between the center of the two approaching nuclei. It is a para...
The "Molecule Cloud View" module allows you to visualize a group of molecules as their respective van der Waals surfaces within 3D datasets, specifying their positions and orientations. To use this feature, you need a molecule template, such as one from the Protein Data ...

How do Van der Waals bonds differ from covalent bonds? If the difference in electronegativity between two atoms in a molecule is very large, the forces holding the atoms together are likely to be: a. dipole-dipole b. ionic c. non-polar covalent d. hyd...
What is the difference between van der Waals and London dispersion? Describe the difference between fluorescence and phosphorescence. Explain the difference in the C=O stretches in 2-naphthaldehyde and benzophenone. What is the difference between Democritus and Dalton? Elaborate thoroughly. ...
There a some chemical bonds (glue is an extreme example), there are electrical effects (likevan der waals), and then there are effects from simple physical barriers. A pair of rough surfaces will have more friction than a pair of smooth surfaces, because the “peaks” of one surface can ...
In the ever-evolving fields of scientific research and industry, there is a consistent requirement for effective processing and management of imaging datasets. Addressing this need, Thermo Scientific software solutions are continually advancing, offering a diverse range of tools and...
