Texture- and particle-dynamics in these field-induced states, and on crossing transition lines, are explored by image time-correlation and dynamic light scattering, respectively. At relatively low frequencies, starting from a system within the isotropic-nematic coexistence region, a transition from a nematic to a chiral nematic is observed, as well as a dynamical state where nematic domains melt and reform. These transitions are preliminary due to field-induced dissociation/association of condensed ions. At higher frequencies a uniform state is formed that is stabilized by hydrodynamic interactions through field-induced electro-osmotic flow where the rods align along the field direction. There is a point in the field-amplitude vs. frequency plane where various transition lines meet. This point can be identified as a “non-equilibrium critical point,” in the sense that a length scale and a time scale diverge on approach of that point. The microscopic dynamics exhibits discontinuities on crossing transition lines that were identified independently by means of image and signal correlation spectroscopy. 000186475 536__ $$0G:(DE-HGF)POF2-451$$a451 - Soft Matter Composites (POF2-451)$$cPOF2-451$$fPOF II$$x0 000186475 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000186475 773__ $$0PERI:(DE-600)2721033-9$$a10.3389/fphy.2014.00073$$gVol. 2$$p73$$tFrontiers in Physics$$v2$$x2296-424X$$y2014 000186475 8564_ $$uhttps://juser.fz-juelich.de/record/186475/files/FZJ-2015-00549.pdf$$yOpenAccess 000186475 8564_ $$uhttps://juser.fz-juelich.de/record/186475/files/FZJ-2015-00549.jpg?subformat=icon-144$$xicon-144$$yOpenAccess 000186475 8564_ $$uhttps://juser.fz-juelich.de/record/186475/files/FZJ-2015-00549.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000186475 8564_ $$uhttps://juser.fz-juelich.de/record/186475/files/FZJ-2015-00549.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000186475 8767_ $$92014-11-19$$d2014-11-20$$eAPC$$jZahlung erfolgt 000186475 909CO $$ooai:juser.fz-juelich.de:186475$$pdnbdelivery$$popenCost$$pVDB$$pdriver$$pOpenAPC$$popen_access$$popenaire 000186475 915__ $$0LIC:(DE-HGF)CCBY3$$2HGFVOC$$aCreative Commons Attribution CC BY 3.0 000186475 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000186475 915__ $$0StatID:(DE-HGF)0500$$2StatID$$aDBCoverage$$bDOAJ 000186475 9141_ $$y2014 000186475 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130749$$aForschungszentrum Jülich GmbH$$b0$$kFZJ 000186475 9132_ $$0G:(DE-HGF)POF3-551$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vFunctional Macromolecules and Complexes$$x0 000186475 9131_ $$0G:(DE-HGF)POF2-451$$1G:(DE-HGF)POF2-450$$2G:(DE-HGF)POF2-400$$3G:(DE-HGF)POF2$$4G:(DE-HGF)POF$$aDE-HGF$$bSchlüsseltechnologien$$lBioSoft$$vSoft Matter Composites$$x0 000186475 920__ $$lyes 000186475 9201_ $$0I:(DE-Juel1)ICS-3-20110106$$kICS-3$$lWeiche Materie$$x0 000186475 9801_ $$aFullTexts 000186475 980__ $$ajournal 000186475 980__ $$aVDB 000186475 980__ $$aUNRESTRICTED 000186475 980__ $$aFullTexts 000186475 980__ $$aI:(DE-Juel1)ICS-3-20110106 000186475 980__ $$aAPC
