The present study concerns oxygen-ion transfer between yttriastabilized zirconia single crystals (YSZ/YSZ) under mechanical contact stress. Two YSZ single crystal plates were piled up between platinum meshes, and contact stress was mechanically applied. The interfacial conductivity as well as the bulk conductivity was successfully measured with this setup. The interfacial conductivity is greatl...

سیستم های پیل سوختی راکتورهای الکتروشیمیایی هستند که در حضور هیدروژن و اکسیژن، تولید الکتریسیته، آب و حرارت می کنند. بدلیل بازدهی بالا و عدم آلایندگی محیط زیست، جایگزین مناسبی برای مبدل های با سوخت های فسیلی نظیر موتورهای احتراق داخلی هستند. سوخت مورد نیاز پیل های سوختی، هیدروژن و یا هیدروکربن های گازی، مایع و جامد هستند. پیل سوختی اکسید جامد در بین انواع مختلف پیل سوختی، بالاترین بازدهی و ساخت...

Using van der Pauw method, the conductivity of disk samples La0.7Sr0.3MnO3±? (LSM) and La0.6Sr0.4Co0.2Fe0.8O3?? (LSCF) in a Ce0.9Gd0.1O2?? (GDC) matrix was accurately quasi-continuously measured over 800 °C to ?73 °C, transition points Arrhenius behavior were systematically obtained from extremum second derivatives. While LSM-containing showed reproducible trajectories, LSCF system exhibited un...

Chromium poisoning as a result of Cr evaporation from the metallic components and subsequent deposition on cathode (i.e., air) side is one most critical degradation mechanisms in solid oxide fuel cell (SOFC) stacks. Recently, LSC La0.6Sr0.4CoO3−δ) exhibited more promising results both electrolysis modes than LSCF La0.58Sr0.4Co0.2Fe0.8O3−δ) due to its higher ionic conductivity, despite relativel...

An overview of the major development of operational modal identification is presented. It includes four time domain approaches, i.e. NExT-type, ARMAV model-based, stochastic realization-based, stochastic subspace-based methods, and two frequency domain approaches, i.e. FDD-type and output-only LSCF-type methods. The internal relation with traditional modal identification using input/output meas...

Several studies have sought the factors that are related to prison adjustment. However, this construct is poorly explored among female populations and even less so in those with characteristics of psychopathy. Thus, present study aims understand adjustment offenders determine role psychopathy criminal lifestyle predicting it. Both institutional infractions health care utilization were used as i...

Solid oxide electrolysis cell (SOEC) is a very efficient hydrogen production technology, but the degradation serious limiting factor for its long-term implementation. Oxygen electrode (OE) delamination reported to be critical mechanism. In this study, we present methodology understand failure of OE due chemical stress in better perspective. Several configurations were tested: baseline strontium...
