(author)The long-term operation of a ceramic-supported 5 μm-thick Pd membrane at 450 °C and 27 bar with a feed representing steam-methane-reforming conditions has been monitored over a period of 100 days. Subsequently, a thorough characterisation of the exposed membrane has been performed to investigate leakage behavior and microstructural changes to...article 2018

Theelen, M. (author), Dasgupta, S. (author), Vroon, Z. (author), Kniknie, B. (author), Barreau, N. (author), van Berkum, J. (author), Zeman, M. (author)Aluminum doped zinc oxide (ZnO:Al) layers were exposed to the atmospheric gases carbon dioxide (CO2), oxygen (O2), nitrogen (N 2) and air as well as liquid H2O purged with these gases, in order to investigate the chemical degradation behavior of these layers. The samples were analyzed by electrical, compositional and optical measurements before,...article 2014

(author)Sputtered aluminum doped zinc oxide (ZnO:Al) layers on borosilicate glass were exposed to damp heat (85 C/85% relative humidity) for 2876 h to accelerate the physical and chemical degradation behavior. The ZnO:Al samples were characterized by electrical, compositional and optical measurements before and after degradation. Hall measurements show...article 2014

(author)In this work, the structural, electrical, and optical properties as well as chemical bonding state of Al-doped ZnO films deposited by atomic layer deposition have been investigated to obtain insight into the doping and electrical transport mechanisms in the films. The range in doping levels from 0% to 16.4% Al was accomplished by tuning the...article 2013

(author)While it is known that the charge-carrier mobility in organic semiconductors is only weakly dependent on the electric field at low fields, the experimental mobility in organic field-effect transistors using silylethynyl-substituted pentacene is found to be surprisingly field dependent at low source-drain fields. Corroborated by scanning Kelvin...article 2012
