I have some very small spherical particles with diameter of 1 mm and i would like to know coefficient of friction between them. Can anyone suggest an experiment/device that would help me?
In order to get friction between a plate and particle i can use tilt test and measure the angle at which...
Ok i found that AMBER force field parameters are avalible on their homepage: http://amber.scripps.edu/ and there is also a link to some other page where they have a nice file: http://www.chpc.utah.edu/~cheatham/cornell_all_prm
But anyway i would like more LJ parameters if you have.. see PM please.
Thank you for your links!
The last one looks the most interesting to me.
I am interested in organic compound.. so mainly C H O N P S elements.
I can't access the article on wiley page though.
I am looking for some force field parameters for nonbonded forces between atoms.
In most molecular modeling programs Lennard-Jones function is used to calculate Van der Waals forces where sigma and epsilon are constant values for a pair of atoms. But i cannot find them anywhere.
Or if...
