Improvement in the Adhesion Between Electrode of a SOFC and Ag Paste as a Current Collector by Au Deposition

引用

Journal of Materials Science & Technology 2015年第3期31卷 257-263页

作者： Sang Koo Jeon Seung Hoon Nahm Oh Heon kwon Department of Safety Engineering Pukyong National University Center for Energy Materials Metrology Korea Research Institute or Standards and Science

This paper reports the use of Au films to improve the performance of the stacked solid oxide fuel cell(SOFC) based on the characterization of the interface and the adhesion between the electrodes of the SOFCs and the Ag paste. The specimens were manufactured to perform the experiment as follows. A Si O2 wafer with a 300 mm notch was attached to the electrodes of a SOFC by a Ag paste and Au film, which were deposited on the electrodes by sputtering for 1 min or 5 min deposition time and annealed at300 C for 1 h. The four-point bending test was performed, which resulted in the formation of an extended crack at the tip on the wafer notch, and the crack propagation was observed using a stereo microscope equipped with a charge-coupled device(CCD). Consequently, the interfacial adhesion energy and the effect of the Au film between the each electrode and the Ag paste can be evaluated. On the cathode, the interfacial adhesion energy without Au film was 2.59 J/m2(upper value) and the adhesion energy increased to 11.59 J/m2(upper value) and 15.89 J/m2(lower value) with the Au film. On the anode,the interfacial adhesion energy without Au film was 1.74 J/m2(upper value), which increased to 11.07 J/m2(upper value) and 14.74 J/m2(lower value) with the Au film. In addition, the interface areas were analyzed by scanning electron microscopy(SEM) and energy dispersive spectroscopy(EDS) to estimate the interface delamination.

A prototype online database-enabled design framework for wind analysis/design of low-rise buildings

Frontiers of Structural and Civil Engineering 2016年第1期10卷 121-130页

作者： Dae Kun kwon Ahsan KAREEM Deepak KUMAR Yukio TAMURA NatHaz Modeling Laboratory Department of Civil & Environmental Engineering & Earth Sciences University of Notre DameNotre Dame IN 46556 USA Department of Ocean Engineering Indian Institute of Technology Madras Chennai 600036 India Department of Architectural Engineering Tokyo Polytechnic University Tokyo 243-0297 Japan

This study presents a development of an advanced cyberbased database-enabled design module for low- rise buildings （DEDM-LR） which provides estimation of the wind-induced responses for main wind force resisting frames by making direct use of pressure time histories measured at a large number of pressure taps over a suite of building models. These responses may be considered in lieu of code-specified load effects in which the overall accuracy may be influenced by the inherent simplifications in codes. In addition, this new automated approach is particularly attractive and advantageous as it allows a web-based online analysis/design via intuitive user-friendly interfaces for both the input and output in terms of familiar web-style forms that are nowadays very common in most of web-based services. Presently, the DEDM-LR hosts an aerodynamic database developed by the Tokyo Polytechnic University （TPU）, Japan for a variety of building configurations like flat, gable, and hip roofs under suburban terrain flow condition with immediate application to other databases. The paper shows the efficacy and validity of the DEDM-LR by walking through its details and examples on selected gable-roofed buildings. The architecture of DEDM-LR platform offers the ability to pool resources by hosting other databases that may become available in the near future.

AIM To compare the value of contrast-enhanced abdominal computed tomography(CT) and fluorodeoxyglucose(FDG) positron emission tomography/computed tomography(PET/CT) for detecting gastric carcinoma *** We retrospectively examined data from 2475 patients who underwent both contrast-enhanced abdominal CT and FDG PET/CT for the surveillance of gastric carcinoma curative resection. Patients had an interval of less than 1 mo between their CT and PET/CT scans. Sixty patients who had recurrence were enrolled. Among 1896 patients who did not have recurrence, 60 were selected by simple random sampling. All CT and PET/CT images were reviewed retrospectively by two reviewers blinded to all clinical and pathologic information except curative resection due to gastric carcinoma. RESULTS The pathological stage of the recurrence group was statistically significantly higher than that of the control group(P < 0.001). In the 60 patients who had recurrence, there were 79 recurrent lesions. Fortyfour patients had only one location of recurrence, 13 patients had two locations, and 3 patients had three. In the detection of patient-based overall recurrence, no statistically significant differences existed between the two modalities(P = 0.096). However, for peritoneal carcinomatosis, CT had a statistically significantly higher sensitivity compared to PET/CT(96% vs 50%, P = 0.001). Adenocarcinoma was the most common type of gastric carcinoma. On the pathology-based analysis, CT also had a statistically significantly higher sensitivity compared to PET/CT(98% vs 80%, P = 0.035).CONCLUSION Contrast-enhanced CT was superior to PET/CT in the detection of peritoneal carcinomatosis and pathologic type of adenocarcinoma.

As smaller structures are being increasingly adopted in the semiconductor industry,the performance of memory and logic devices is being continuously improved with innovative 3D integration schemes as well as shrinking and stacking *** to the increasing complexity of the design architectures,optical metrology techniques including spectroscopic ellipsometry(SE)and reflectometry have been widely used for efficient process development and yield ramp-up due to the capability of 3D structure ***,there has been an increasing demand for a significant reduction in the physical spot diameter used in the SE technique;the spot diameter should be at least 10 times smaller than the cell dimension(~30×40μm2)of typical dynamic random-access memory to be able to measure in-cell critical dimension(CD)*** this end,this study demonstrates a novel spectrum measurement system that utilizes the microsphere-assisted super-resolution effect,achieving extremely small spot spectral metrology by reducing the spot diameter to~210 nm,while maintaining a sufficiently high signal-to-noise *** addition,a geometric model is introduced for the microsphere-based spectral metrology system that can calculate the virtual image plane magnification and depth of focus,providing the optimal distance between the objective lens,microsphere,and sample to achieve the best possible imaging *** proof of concept was fully verified through both simulations and experiments for various ***,owing to its ultra-small spot metrology capability,this technique has great potential for solving the current metrology challenge of monitoring in-cell CD variations in advanced logic and memory devices.
