Frequenzanalyse von Zeitsignalen, phenomenon are not fully understood. In a formerwork we showed that the tribo-electric charging of polymer particles can be described by their electronpair acceptor and donator properties. But polymer charging cannot be fully explained on a molecularlevel. During the collision of two particles expa

Grundlegende maschinenakustische Begriffe,e generation of sulfonic acid groups at the polyethylene surfaces and the degree of photosulfonation were examined by FTIR-spectroscopy, contact angle testing as well as zeta potential measurements. The contact angle θ of water decreased from θ = 99° (pristine LDPE) to about θ = 30° (photosulfonated

The surface was built up fromself-assembled submicrometer- and micrometer-sized monodisperse core-shell particles of differentradius (0.1–10 μm) forming ordered arrays. In this way, an increase in the verticalroughness is achieved with increasing particle radius, but without changing the W

Abstrahlung von Luftschallwellen,balanced capillary forces. A newconcept to reduce the pattern collapse bases on the reduction of the capillary forces by adsorptionof a cationic surfactant. The application of a cationic surfactant rinse step in the photolithographicprocess leads to a reduction of the pattern collapse. Physico-chemi

We find that the shells show a linear force-deformation characteristic for deformationsof the order of the shell wall thickness. This experimental outcome is discussed in terms of analyticalresults of continuum mechanics, in particular the scalin
