Three relaxation processes were observed in the composite HIPS films. The first one (a-relaxation peak) appeared at about 93 degrees C and represented the glass transition. The second peak p was a high-temperature part of the first one and overlapped it. The p peak was caused by the release and subsequent motion of excess charges deposited during the electret preparation or the polarization process. The third peak appeared at about 150 degrees C and occurred only in the spectra of the composite films. The overlapping peaks were separated by the thermal cleaning technique. The subsequent application of the numerical methods (the Tikhonov regularization technique) allowed to determine the activation energy of the second process and to compare the obtained value with the corresponding data on the dielectric relaxation.}, language = {ru} } @article{Daute1995, author = {Daute, Daniela}, title = {{\"U}bermolekulare Strukturbildung durch Selbstorganisation neuer discoider Arylaminotriazine and assoziierter Alkoxybenzoate}, year = {1995}, language = {de} } @article{Mikelskis1993, author = {Mikelskis, Helmut}, title = {Zur {\"O}kologisierung des Lernprozesses : Versuch {\"u}ber einen vernachl{\"a}ssigten Aspekt von Umweltbildung}, isbn = {3-89088-073-8}, year = {1993}, language = {de} } @article{Starauschek2006, author = {Starauschek, Erich}, title = {Zur Rolle der Sprache beim Lernen von Physik}, isbn = {3-589-22148-8}, year = {2006}, language = {de} } @article{FruhnerCzichocki1996, author = {Fruhner, Horst and Czichocki, G.}, title = {Zur Bestimmung der kritischen Mizellkonzentration (CMC)}, year = {1996}, language = {de} } @article{Mikelskis1993, author = {Mikelskis, Helmut}, title = {Zukunftsperspektiven physikdidaktischer Forschung im vereinigten Deutschland}, isbn = {3-88064-223-0}, year = {1993}, language = {de} } @article{Mikelskis2001, author = {Mikelskis, Helmut}, title = {Zukunftsperspektiven der Bildung im Informationszeitalter und in der Wissensgesellschaft}, year = {2001}, language = {de} } @article{TrollBeimGraben1998, author = {Troll, G{\"u}nter and Beim Graben, Peter}, title = {Zipfs law is not a consequence of the central limit theorem}, year = {1998}, language = {en} } @article{BlasiusToenjes2009, author = {Blasius, Bernd and Toenjes, Ralf}, title = {Zipf's Law in the popularity distribution of chess openings}, issn = {0031-9007}, doi = {10.1103/Physrevlett.103.218701}, year = {2009}, abstract = {We perform a quantitative analysis of extensive chess databases and show that the frequencies of opening moves are distributed according to a power law with an exponent that increases linearly with the game depth, whereas the pooled distribution of all opening weights follows Zipf's law with universal exponent. We propose a simple stochastic process that is able to capture the observed playing statistics and show that the Zipf law arises from the self-similar nature of the game tree of chess. Thus, in the case of hierarchical fragmentation the scaling is truly universal and independent of a particular generating mechanism. Our findings are of relevance in general processes with composite decisions.}, language = {en} } @article{LangeReiterKniepertetal.2015, author = {Lange, Ilja and Reiter, Sina and Kniepert, Juliane and Piersimoni, Fortunato and Paetzel, Michael and Hildebrandt, Jana and Brenner, Thomas J.

This approach relies on the formation of dense and homogeneous self-assembled monolayers based on phosphonic acids with different dipole moments. This allows us to apply ZnO as charge selective bottom electrodes in either regular or inverted solar cell structures, using poly(3-hexylthiophene): phenyl-C71-butyric acid methyl ester as the active layer. These devices compete with or even surpass the performance of the reference on indium tin oxide/poly(3,4-ethylenedioxythiophene) polystyrene sulfonate. Our findings highlight the potential of properly modified ZnO as electron or hole extracting electrodes in hybrid optoelectronic devices. (C) 2015 AIP Publishing LLC.}, language = {en} }
