Crystal Structure of Fiber Structured Pentacene Thin Films - A Crystal Truncation Rod Study Using Synchrotron X-Rays
ISBN: 9783836493635 / Angielski / Miękka / 2008 / 164 str. Termin realizacji zamówienia: ok. 13-18 dni roboczych. It is widely recognized that the intrinsic charge transport properties in organic thin-film transistors (OTFTs) depend strongly on the crystal structure of the organic semiconductor layer. Pentacene, showing one of the highest charge carrier mobilities among organic semiconductors, is known to crystallize in at least four polymorphs, which can be distinguished by their layer periodicity d(001). Only two polymorphs grow as single crystals, and their detailed crystal structure has been solved. The substrate-induced 15.4 Å polymorph is the most relevant for OTFT applications; however, its...

Clinical Echo-Encephalography
ISBN: 9783642487231 / Angielski / Miękka / 2012 / 224 str. Termin realizacji zamówienia: ok. 20 dni roboczych. Echo-encephalography, introduced by LEKS ELL in 1955, has gained increasing importance for the early detection of numerous intracranial lesions in the last decade. The main advantage of this diagnostic procedure lies in the fact that it permits a rapid orientation about the spatial relationships within the skull without stressing or endangering the patient. Although this method alone only rarely allows a complete diagnosis, the echo-encephalographic findings always indicate which further diagnostic measures are most suitable for establishing the diagnosis with the greatest accuracy in every...
