While the latter localized motions are known to take place on the picosecond time scale and Angstrom length scale, the slower motions that we have observed are found on the nanosecond time scale and nanometer length scale. They are associated with the slow secondary relaxations, or excess wing dynamics, in glass-forming liquids. Our approach, therefore, can be applied to probe the characteristic length scale of the dynamic entities associated with slow dynamics in glass-forming liquids, which presently cannot be studied by other experimental techniques. 000187636 536__ $$0G:(DE-HGF)POF3-551$$a551 - Functional Macromolecules and Complexes (POF3-551)$$cPOF3-551$$fPOF III$$x0 000187636 536__ $$0G:(DE-HGF)POF3-6G4$$a6G4 - Jülich Centre for Neutron Research (JCNS) (POF3-623)$$cPOF3-623$$fPOF III$$x1 000187636 536__ $$0G:(DE-HGF)POF3-6215$$a6215 - Soft Matter, Health and Life Sciences (POF3-621)$$cPOF3-621$$fPOF III$$x2 000187636 588__ $$aDataset connected to CrossRef, juser.fz-juelich.de 000187636 7001_ $$0P:(DE-Juel1)136992$$aZolnierczuk, P.$$b1$$ufzj 000187636 7001_ $$0P:(DE-Juel1)130872$$aOhl, M.$$b2$$ufzj 000187636 773__ $$0PERI:(DE-600)1476244-4$$a10.1039/C4CP05081A$$gVol. 17, no. 6, p. 4466 - 4471$$n6$$p4466 - 4471$$tPhysical chemistry, chemical physics$$v17$$x1463-9084$$y2015 000187636 8564_ $$uhttps://juser.fz-juelich.de/record/187636/files/FZJ-2015-01262.pdf$$yRestricted 000187636 909CO $$ooai:juser.fz-juelich.de:187636$$pVDB 000187636 915__ $$0StatID:(DE-HGF)0100$$2StatID$$aJCR 000187636 915__ $$0StatID:(DE-HGF)0110$$2StatID$$aWoS$$bScience Citation Index 000187636 915__ $$0StatID:(DE-HGF)0111$$2StatID$$aWoS$$bScience Citation Index Expanded 000187636 915__ $$0StatID:(DE-HGF)0150$$2StatID$$aDBCoverage$$bWeb of Science Core Collection 000187636 915__ $$0StatID:(DE-HGF)0199$$2StatID$$aDBCoverage$$bThomson Reuters Master Journal List 000187636 915__ $$0StatID:(DE-HGF)0200$$2StatID$$aDBCoverage$$bSCOPUS 000187636 915__ $$0StatID:(DE-HGF)0300$$2StatID$$aDBCoverage$$bMedline 000187636 915__ $$0StatID:(DE-HGF)0310$$2StatID$$aDBCoverage$$bNCBI Molecular Biology Database 000187636 915__ $$0StatID:(DE-HGF)0400$$2StatID$$aAllianz-Lizenz / DFG 000187636 915__ $$0StatID:(DE-HGF)0420$$2StatID$$aNationallizenz 000187636 915__ $$0StatID:(DE-HGF)1150$$2StatID$$aDBCoverage$$bCurrent Contents - Physical, Chemical and Earth Sciences 000187636 915__ $$0StatID:(DE-HGF)9900$$2StatID$$aIF < 5 000187636 9141_ $$y2015 000187636 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)136992$$aForschungszentrum Jülich GmbH$$b1$$kFZJ 000187636 9101_ $$0I:(DE-588b)5008462-8$$6P:(DE-Juel1)130872$$aForschungszentrum Jülich GmbH$$b2$$kFZJ 000187636 9130_ $$0G:(DE-HGF)POF2-451$$1G:(DE-HGF)POF2-450$$2G:(DE-HGF)POF2-400$$aDE-HGF$$bSchlüsseltechnologien$$lBioSoft: Makromolekulare Systeme und biologische Informationsverarbeitung$$vSoft Matter Composites$$x0 000187636 9130_ $$0G:(DE-HGF)POF2-54G24$$1G:(DE-HGF)POF2-540$$2G:(DE-HGF)POF2-500$$aDE-HGF$$bStruktur der Materie$$lForschung mit Photonen, Neutronen und Ionen (PNI)$$vJCNS$$x1 000187636 9131_ $$0G:(DE-HGF)POF3-551$$1G:(DE-HGF)POF3-550$$2G:(DE-HGF)POF3-500$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$aDE-HGF$$bKey Technologies$$lBioSoft – Fundamentals for future Technologies in the fields of Soft Matter and Life Sciences$$vFunctional Macromolecules and Complexes$$x0 000187636 9131_ $$0G:(DE-HGF)POF3-623$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6G4$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vFacility topic: Neutrons for Research on Condensed Matter$$x1 000187636 9131_ $$0G:(DE-HGF)POF3-621$$1G:(DE-HGF)POF3-620$$2G:(DE-HGF)POF3-600$$3G:(DE-HGF)POF3$$4G:(DE-HGF)POF$$9G:(DE-HGF)POF3-6215$$aDE-HGF$$bForschungsbereich Materie$$lVon Materie zu Materialien und Leben$$vIn-house research on the structure, dynamics and function of matter$$x2 000187636 9201_ $$0I:(DE-Juel1)ICS-1-20110106$$kICS-1$$lNeutronenstreuung$$x0 000187636 9201_ $$0I:(DE-Juel1)JCNS-1-20110106$$kNeutronenstreuung ; JCNS-1$$lNeutronenstreuung$$x1 000187636 9201_ $$0I:(DE-Juel1)JCNS-SNS-20110128$$kJCNS-SNS$$lJCNS-SNS$$x2 000187636 980__ $$ajournal 000187636 980__ $$aVDB 000187636 980__ $$aI:(DE-Juel1)ICS-1-20110106 000187636 980__ $$aI:(DE-Juel1)JCNS-1-20110106 000187636 980__ $$aI:(DE-Juel1)JCNS-SNS-20110128 000187636 980__ $$aUNRESTRICTED 000187636 981__ $$aI:(DE-Juel1)IBI-8-20200312 000187636 981__ $$aI:(DE-Juel1)JCNS-1-20110106 000187636 981__ $$aI:(DE-Juel1)JCNS-1-20110106 000187636 981__ $$aI:(DE-Juel1)JCNS-SNS-20110128
