(3) For the tangential sliding and rolling of particle are influenced by the friction between the particles, in addition to the Poisson's ratio, shear modulus and density of the materials properties of particles, the friction coefficient of particles should be defined in EDEM [4].
In addition to the Poisson's ratio, shear modulus and density of the materials properties of sleepers and tamping tines, the dynamic properties of tamping tines should be defined in EDEM.

Due to their material base of intrinsically active materials (phase-changeable polymers), the ICs are suitable for large-scale integration and offer the possibility of active decision-making capabilities regarding chemical information.
The microchip presented in this paper shows an example of such a µCHMS IC based on intrinsically active materials.
Additionally, the research will discuss the suitability of an alternative material base to fabricate channel structures and especially the separating membranes Acknowledgements We would like to thank the German Research Foundation (A.R., M.A.), the Saxon State Ministry for Science and the Arts and the European Science Foundation (R.G.) for funding.
