Michael Saliba,Simonetta Orlandi,Taisuke Matsui,Sadig Aghazada,Marco Cavazzini,Juan-Pablo Correa-Baena,Peng Gao,Rosario Scopelliti,Edoardo Mosconi,Klaus Hermann Dahmen,Filippo De Angelis,Antonio Abate,Anders Hagfeldt,Gianluca Pozzi,Michael Graetzel,Mohammad Khaja Nazeeruddin +15 more
TL;DR: In this article, a molecularly engineered hole-transport material with a simple dissymmetric fluorene-dithiophene core substituted by N,N-di-p-methoxyphenylamine donor groups is presented.
Journal ArticleDOI
Enhancement of thermal and electrical properties of carbon nanotube polymer composites by magnetic field processing
Eun Sang Choi,James S. Brooks,D. L. Eaton,Marwan Al-Haik,M. Y. Hussaini,Hamid Garmestani,Dongsheng Li,Klaus Hermann Dahmen +7 more
TL;DR: In this paper, the thermal and electrical properties of single wall carbon nanotube (CNT)-polymer composites are significantly enhanced by magnetic alignment during processing, and the electrical transport properties are mainly governed by the hopping conduction with localization lengths comparable to bundle diameters.
Journal ArticleDOI
Polymer‐Mediated Alignment of Carbon Nanotubes under High Magnetic Fields

Journal ArticleDOI
Organometallic chemical vapor deposition of high Tc superconducting films using a volatile, fluorocarbon-based precursor
Jing Zhao,Klaus Hermann Dahmen,Henry O. Marcy,L. M. Tonge,Tobin J. Marks,Bruce W. Wessels,Carl R. Kannewurf +6 more
TL;DR: In this article, the high Tc superconductor YBa2Cu3O7−δ has been prepared by organometallic chemical vapor deposition using the volatile metalorganic precursors Cu(acetylacetonate)2, Y(dipivaloylmethanate)3, and Ba(heptafluorodimethyloctanedionate), and with argon as a carrier gas and water vapor as a reactant, film growth rates of 10-30 nm/min are achieved.
Journal ArticleDOI
Hybrid carbon fiber/carbon nanotube composites for structural damping applications.
Mehran Tehrani,Masoud Safdari,Ayoub Yari Boroujeni,Z Razavi,Scott W. Case,Klaus Hermann Dahmen,Hamid Garmestani,Marwan Al-Haik +7 more
TL;DR: The results indicated that the energy dissipation in the GSD-grown MWCNTs composite can be primarily attributed to the frictional sliding at the nanotube/epoxy interface and to a lesser extent to the stiff thermal shielding SiO2 film on the fiber/matrix interface.
