By changing the mechanical device or processing time, three composite powders with different size distributions were obtained. Then the powders were formed into cathodes of solid oxide fuel cells (SOFCs). The microstructures of the cathodes were carefully characterized by scanning electron microscope (SEM). Losses by internal resistance (IR) and by polarization between the electrolyte and cathode were measured with the current interruption technique. The cathode fabricated by using the powder with the narrowest particle size distribution showed fine grains, uniform porous structure and good contact with the electrolyte layer, thereby resulting in low IR and polarization losses. In contrast, the cathode fabricated from the powder with the broadest particle size distribution contained a large mass of coarse particles and had less uniform structure in the grains and pores, thereby resulting in relatively high IR and polarization losses.","PeriodicalId":364039,"journal":{"name":"2007 2nd IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127804657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this work is to reveal the underlying mechanism behind LADI and to quantitatively characterize important imprinting parameters which dominate a successful LADI process. The theoretical modeling consists of three elements, the time-history of silicon melting when subjected to pulsed laser heating, the elastodynamic movement of mold's surface under resistance pressure, and the squeezing out of the molten silicon layer under the pressure from the walls. We have accurately determined the governing equations for each physical problem and derive the interaction relationship between them. A numerical scheme is developed to modeling the whole LADI process. The role of each important factor such as laser fluence, contact pressure, viscosity of molten substance and mold's feature size can be understood and visualized through this model and their influences on the final imprinting depth are also quantitatively determined.","PeriodicalId":364039,"journal":{"name":"2007 2nd IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127839537","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In general, fluorescent dye can be excited with light sources in a specific wavelengths then the excited fluorescence emits light with longer wavelengths such that a special filter set on a fluorescence microscope is required for this application. Instead of using conventional laser induced fluorescence scheme, this study adopts a diascopic illumination light source for fluorescence excitation and an UV-VIS-NIR spectrometer for emission signals detection. Multiple fluorescence dyes can be excited and detected simultaneously in a single CE channel with this approach. In addition, the proposed system is simple and low-cost since no sophisticated optical filter sets and laser sources are required for the detection purpose. Experimental result shows that the proposed system is feasible for parallel detecting a mixed fluorescence sample in a single run. Fluorescence dyes including Atto 610, Rhodamine B and FITC are successfully detected and identified simultaneously. The LOD (limit of detection) for detecting FITC fluorescence of the proposed system can be as low as 10-5 M(SNR=5.56) which is applicable for to general bio-analytical applications.","PeriodicalId":364039,"journal":{"name":"2007 2nd IEEE International Conference on Nano/Micro Engineered and Molecular Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115710698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Most of our applications are devoted to nanoelectronics right now reaching from semiconductor device models to nanowire simulations. The online simulation facility has been operational for over ten years now and has served traditionally around 1,000 simulation users annually. The simulation tool delivery and the simulation tools have been completely overhauled in the past 18 months and over 4,200 users have run over 138,000 simulations. The introduction of interactive lectures on nanotechnology, in the form of tutorials, research seminars, and classes in the year 2004 has propelled the nanoHUB user base to over 18,700. The simulation tools available on the nanoHUB can address issues in quantum dots, resonant tunneling diodes, carbon nanotubes, PN-junctions, MOS capacitors, MOSFETs, nanowires, ultra-thin-body MOSFETs, and others.
