Aberration Corrected Electron Microscopy: What are the New Perspectives for Materials Sciences?Dr. C. Kisielowski
National Center for Electron Microscopy, LBNL
Berkeley CA ABSTRACT Ongoing technological advancements of electron microscopy will reshape the way electron scattering is utilized to investigate structure and composition of materials down to the atomic level. It foreseeable (and partly established) that electron microscopes will have the ability to image single atoms of most elements of the periodic table of elements and to tie the spatial information to spectroscopy, which probes for chemical constituents and local bonding. Therefore, a three-dimensional materials characterization can reach towards atomic resolution and it is feasible to solve the long-standing problem of information loss that comes from projecting the 3D materials structure into a 2D image plane.
This talk highlights how much materials science already benefits from recent advancement of instrumentation. Application examples include a characterization of a dislocation in GaAs in terms of displacement fields and impurity segregation, investigations of strain relaxation processes in FePt nanoparticles, and investigations of local band gap fluctuations that are induced by indium clusters in GaN/InGaN/GaN quantum wells. The given examples also point to current limitations that will be removed by the next generation of fully aberration corrected microscopes, which are currently developed within the DoE s TEAM-Project.Thursday, January 12, 2006

From Nature to Engineering: Biotechnology, Biomimetics, and Bio-Inspiration Opens Novel Routes to Metal Oxide Semiconductors.David J. KisailusMaterials Research Laboratory/ California NanoSystems Institute/
Institute for Collaborative Biotechnologies
University of California Santa Barbara We discovered that the specific proteins found in marine sponges that enzymatically produce silica (i.e., “silicateinsâ€Â), catalyze and structurally direct the hydrolysis and polycondensation of the molecular precursors of such metal oxides as gallium oxide, titanium dioxide, and zinc oxide. These are the first reported examples of enzyme-catalyzed, nanostructure-directed synthesis of these materials â€" and the first such syntheses at low temperature and neutral pH. Interestingly, interaction with the template-like protein surface is capable of stabilizing polymorphs of these materials that otherwise are not normally observed at low temperatures. Thus, for example, nanocrystallites of anatase titanium dioxide and gamma-gallium oxide are formed on the protein at room temperature. Perhaps most remarkably, in some of these cases the interaction between the condensing metal oxide and the protein results in preferential alignment of the resulting nanocrystallites of the mineral, suggesting an epitaxial-like relationship between the mineral crystallite and specific functional groups on the templating protein surface. Recent results confirm our suspicions that the underlying protein has a crystalline structure capable of producing a repetitive crystalline template upon which the metal oxide may order.
Biomimickry is currently being used to catalyze and template the growth of various metal oxides. We are incorporating analogs of the critical amino acid residues found in silicatein’s catalytic active site, anchoring these functional groups (via self-assembled monolayers on gold) adjacent to one another to facilitate catalytic activity by the same mechanism exhibited by the enzyme. Results have shown that biomimetics of the active site in silicatein are capable of producing silica from alkoxide precursors at neutral pH.
We presently are attempting to extend the genetic engineering approach described above to identify and then harness the natural structure-directing determinants of the protein and use the key control mechanisms identified in biomineralizing organisms towards the low-temperature, benign synthesis of nanostructured materials for optical and electrical materials, sensors, and pharmaceuticals.January 13, 2005

Spectral Theory for Nonlinear Dynamical Systems

Speaker:Prof. Igor MezicDepartment of Mechanical Engineering
University of California, Santa Barbara
Santa Barbara, CAAbsractNonlinear dynamical systems theory relies mainly on geometric tools of the type first employed by Poincare. In this talk we show how a lifting (representation) of the action of a nonlinear dynamical system to a linear, Koopman operator action on an infinite-dimesional Hilbert space of observables leads to methods of analysis of nonlinear dynamical systems in spectral terms. This theory, that relies on tools developed originally by Wiener, von Neumann and Koopman, is used to address questions of model validation and model reduction for high-dimensional, nonlinear systems. Much use is made of linking geometric concepts such as attractors and stable and unstable manifolds to spectral properties of the Koopman operator. When an adjoint (Perron-Frobenius) lifting is used, problems related to uncertainty propagation can be treated. For high-dimensional systems, graph theory methods are used in conjunction with the Perron-Frobenius lifting to address those.

Graduate Seminar"Subspace Identification Using the Parity Space"Jin Wang, Ph.D., P.E.
Advanced Micro Devices, IncABSTRACT Subspace identification methods (SIMs) have been one of the main streams of research in system identification. Compared to the prediction error methods (PEMs), SIMs have a better numerical reliability and a modest computational complexity, particularly when the number of outputs and states is large. However, most of the SIMs, like other more traditional PEMs, consider output errors only and assume the input variables are noise-free. Therefore, under the errors-in-variables (EIV) situation, most of the existing SIMs gives biased estimates. Besides, due to the correlation between the input and the unmeasured disturbance under feedback control, many subspace algorithms do not work on closed-loop data, even though the data satisfy identifiability conditions for prediction error methods.
In this talk, I will present a new subspace identification method using the parity space employed in fault detection in the past. The basic algorithm, known as subspace identification method via principal component analysis (SIMPCA), gives consistent estimation of the deterministic part and stochastic part of the system, for both closed-loop and errors-in-variables situation. Two modifications, SIMPCA with column weighting and SIMPCA with modified instrumental variables, are developed to further improve the efficiency/accuracy of SIMPCA. Simulation examples are given to illustrate the performance of the proposed algorithms.Tuesday, January 24, 2006

"Message Ferrying and Other Short Stories: Mobility-Assisted Data Delivery in Wireless Networks"Prof. Mostafa AmmarCollege of ComputingGeorgia Institute of TechnologyGerontology Auditorium (GER-124)Tuesday, January 24, 20062:00-3:00p.m.[A reception will follow at 3:00p.mAbstract:Mobile ad hoc networks form a vital component in realizing the vision of rapidly deployed communications capability in environments with little or no pre-installed infrastructure. Such environments arise in critical situations ranging from battlefield scenarios to natural and human-made disaster events. Most ad hoc network routing and data forwarding algorithms are designed for networks that are always connected. Node mobility, limited radio range, physical obstacles, severe weather, wide deployment area or other physical factors, might preclude some nodes from communicating with others and result in a partitioned network. In this talk, I will summarize our work which is concerned with the development of a "Message Ferrying" (MF) scheme, inspired by its real life analog, that implements a non-traditional "store, carry and forward" routing paradigm using node mobility to overcome network partitioning. In the MF scheme, a set of mobile nodes called message ferries takes responsibility for carrying messages between disconnected nodes. In this talk I will summarize our research efforts in the design and evaluation of efficient data delivery services using message ferrying techniques. These include: 1) design of ferry routing schemes for single and multiple interacting ferries, 2) protocols that make use of proactive node and ferry mobility, and 3) use of message ferries to save energy. I will then place our message ferrying work in the larger context by describing a novel taxonomy for mobile wireless networks, which admits various ranges of disconnection and mobility.Bio:Mostafa Ammar is a Regents' Professor with the College of Computing at Georgia Tech.

Long Beach, CAAbstractOne of the most valuable attributes of hydrogen is that it can be produced by a myriad of production pathways, i.e., hydrogen can be produced from such pathways as natural gas steam reformation, electrolysis and biomass, and can then either be used on-site or distributed to other locations. While all production pathways provide energy diversity benefits, there are differences in the greenhouse gas (GHG) criteria, and toxic pollutant emissions and differences in the amount of petroleum displaced for each pathway.To ensure that the CA H2 Net results in environmental benefits spanning all pollutants the Societal Benefits Topic Team recommended the following goals for the CA H2 Net. These goals are based on Scenarios A, B, and C as described in the Blueprint Plan:1. The CA H2 Net should provide, in the aggregate, a 30 percent reduction in GHG emissions relative to conventional gasoline and diesel vehicles.Source: http://www.hydrogenhighway.ca.gov/plan/reports/sbreport.pdf During this presentation, we will explore the different aspects of the potential of the hydrogen economy - whether it is a hype or hope.

Multi-scale Computational Methods and Application to Modeling of DNA Molecules

Sonny Astani Department of Civil and Environmental Engineering
Conferences, Lectures, & Seminars
Speaker:Prof. J.S. Chen
Department of Civil Engineering
University of California Los AngelesMonday, January 30, 2006 In this presentation, multi-scale computational methods originally developed for computational mechanics will be introduced first. In particular, the "reproducing kernel" and the "wavelet" based multi-scale numerical techniques for solving problems ranging from continuum to quantum scales will be reviewed, and methods for bridging physics in different scales will be given. The extension of multi-scale computational methods to the development of coarse graining technique for modeling DNA molecules will then be presented. The fine-scale molecule simulation of a segment of DNA has been performed. A wavelet based coarse graining approach for modeling DNA molecular structures has been introduced based on the Henderson's theorem. From the fine-scale atomistic simulation results, the distribution functions between centers of mass of two groups of atoms were obtained, and correspondingly the effective potential at fine-scale level was calculated. These fine-scale effective potentials were then homogenized using the multi-scale wavelet projection to yield the coarse-scale potentials between superatoms. These coarse-scale effective potentials were then used to parameterize the force field of the coarse-grained model.Location: Kaprielian Hall (KAP) - 203
