Length and Time Scales of Trapping Processes Associated with CO2 Sequestration
Wed, Apr 02, 2008 @ 02:00 PM - 03:00 PM
Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker: Dr. Hamdi Tchelepi, Stanford University Abstract:
We study the primary CO2 trapping processes in deep saline aquifers:
dissolution and residual trapping. The length and time scales associated with the onset of miscible instability and the long term convective dissolution rates are analyzed using linear stability analysis and high-resolution nonlinear simulations. The migration of CO2 plumes as gravity currents and the effect of residual trapping of the CO2 in the wake of the advancing current are analyzed using a one-dimensional sharp-interface model. We study the behavior of gravity currents in large-scale aquifers with small dip angles, and we discuss issue related to propagation speeds, trapping capacities, and maximum plume migration distances. These preliminary results indicate that CO2 storage in large, deep saline aquifers may be a viable option.Location: Kaprielian Hall (KAP) - 209

Electronically tunable nanomaterials
Wed, Apr 02, 2008 @ 03:30 PM - 04:30 PM
Aerospace and Mechanical Engineering
Conferences, Lectures, & Seminars
Horst HahnForschungszentrum KarlsruheInstitute for Nanotechnology and Joint ResearchLaboratory NanomaterialsTechnische Universität DarmstadtAbstract:The properties of materials are typically controlled in a static manner by the microstructure. This implies control of the grain size, defect concentration, structure and metastability. As long as the microstructure does not change during the use of the material, the properties of the material are fixed, or irreversible. In contrast, in semiconducting materials, properties can be tuned by the application of an external field due to the space charge regions which extend far from the interfaces. In metallic systems, this effect cannot be observed unless the dimensions of the structures are in the nanometer regime. The reason for this different behaviour is the small spatial dimension of the space charge regions due to the effective screening of the induced charges by the conduction electrons.
In nanoporous metals and thin films exposed to appropriate electrolytes, it has been demonstrated that substantial changes of physical properties can be induced by the application of a potential between the nanostructured metal and a counter electrode. Examples of the changes of surface stresses and the electrical resistivity of thin Gold films and nanoporous Gold will be presented. A simple model is proposed based on the modification of the electron density distribution at the interface of the metal and the electrolyte. Effectively, the corresponding change of the effective thickness of the sample is the major cause of the observed resistivity change.
Additionally, a transparent conducting oxide, ITO, in a nanoparticulate form has been prepared from a dispersion using spin coating. The observed resistivity changes, i.e. the on/off ration can be as large as 2.000, i.e. 200.000 %, between the different values of the control potential. Moreover, the device exhibits field effect transistor behavior identical to a conventional semiconductor, but in this case observed in a material with a large charge carrier density exhibiting metallic conduction behaviour. Additionally, the mobility is exceeding 20 cm2/Vs. The device can be used for printable electronics and transparent electronics.

CS Colloq: Acquisition, Compression, and Transfer of Reflectance Fields
Wed, Apr 02, 2008 @ 03:30 PM - 05:00 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Title: Acquisition, Compression, and Transfer of Reflectance FieldsSpeaker: Dr. Pieter Peers (ICT)Abstract:
A reflectance field describes the light transport through a scene in terms of incident and radiant illumination. Full knowledge of a scene's reflectance field allows to view this scene from any viewpoint and under any illumination condition. This simple yet powerful formulation is the basis for many image-based methods, and is the main focus of my research. My research can be categorized into three main topics: acquisition, compression and transfer of reflectance fields. For each of these research topics, a selected contribution is discussed in detail. The first presented contribution describes an acquisition method that enables to capture detailed reflectance fields for image-based relighting using non-adaptive illumination (i.e., measurement) patterns. These measurement patterns are incoherent with the reflectance field itself, and the number of measurement patterns is proportional to the size of the compressed field, rather than the size of full uncompressed field. The second discussed contribution details a novel compression method for (measured) heterogeneous subsurface scattering, i.e., the way light scatters through a non-homogeneous semi-opaque medium. This compression is based on a specially developed matrix factorization method. A third contribution, demonstrates a post-production method that successfully generates plausible relit sequences of dynamic facial performances of a subject. Relighting is achieved by transferring reflectance information from a single reflectance field of a static pose of a potentially different subject, but similar in appearance. In the final part of this presentation, an overview of short term and long term research plans are given. Additionally, some preliminary results of recent research are shown.Biography:
Pieter Peers is currently a senior researcher in the Graphics Lab at the Institute for Creative Technologies (ICT) of the University of Southern California (USC). Before that he was a research assistant in the Computer Graphics Research Group at the K.U.Leuven (Belgium), where he also obtained his Ph.D. in August 2006. His research focuses on data-driven computer graphics, in particular image-based relighting.Location: Henry Salvatori Computer Science Center (SAL) - 322
