[Aspuru-Guzik group list] ANNOUNCEMENT: May 4, 2010 - Prof. Silvija Gradečak

by rtavilla＠rle.mit.edu

Center for Excitonics Seminar Series Announcement The Center for Excitonics is an Energy Frontier Research Center funded by the U.S. Department of Energy, Office of Science and Office of Basic Energy Sciences The Center for Excitonics invites you to join us at the next seminar of the Spring 2010 series. Please forward this information on to others who might be interested in attending this and other center seminars. Title: Semiconductor nanowires: from LEDs to Solar Cells Presenter: Silvija Gradečak Organization: Laboratory for Nanophotonics and electronics Massachusetts Institute of Technology Date: May 4, 2010 Time: 3:00 - 4:00pm Place: Haus Room 36-428 Center URL: http://www.rle.mit.edu/excitonics Seminar URL: http://www.rle.mit.edu/excitonics/gradecak-050410.html Abstract Nanostructured materials – including nanowires, nanotubes, and nanocrystals – have unique and size-tunable properties that depend on the precise arrangement of their atomic constituents. These nanomaterials offer solutions to some of the current challenges in science and engineering, and could potentially lead to improved understanding of the physical world and to discoveries of new phenomena. However, functionality of novel nanomaterials and their impact on society will be ultimately dictated by our understanding and ability to precisely control their structural properties, size uniformity, and dopant distribution at the atomic level. In this talk, I will discuss the growth, doping, and applications of III-V nanowires and nanowire heterostructures using metalorganic chemical vapor deposition, as well as advanced electron microscopy techniques for direct correlation of structural and physical properties with high spatial resolution. We have demonstrated that the cathodoluminescence (CL) technique, coupled with scanning transmission electron microscopy (STEM), effectively bypasses the resolution limit of conventional far-field photoluminescence spectroscopy and allows direct structure-property correlation on the nanoscale. The CL-STEM optical studies of single nanowire heterostructures with spatial resolution of <20 nm will be discussed. Finally, applications of semiconductor nanowires for LED and solar cell applications will be described. Bio Silvija Gradečak is an Assistant Professor of Materials Science and Engineering at MIT. She received her Dipl. Ing. degree in Physics from University of Zagreb, Croatia, in 1999 and her PhD in Physics from EPFL, Switzerland, in 2003. Following two years of postdoctoral research at Harvard University with Prof. Charles Lieber, Gradečak joined the faculty at MIT in 2006. Prof. Gradečak’s group at MIT uses interdisciplinary approach to study semiconductor materials and low-dimensional systems. She held the Merton C. Flemings Career Development Chair and is a recipient of the NSF CAREER Award and 3M Innovation Award.

---------- Forwarded message ---------- From: Tamara Brenner <tamara_brenner(a)harvard.edu> Date: Fri, Apr 23, 2010 at 12:56 AM Subject: Mentoring Workshop on Tuesday To: Ann Georgi <ageorgi(a)fas.harvard.edu> Hi everyone, I'm writing to remind you that Ann and I will be holding the next mentoring workshop this coming Tuesday, April 27. We hope that you will join us! If you are interested, please send me an email. Best, Tamara *Recruiting undergraduates and dealing with challenging situations* At the April 27 workshop, we will discuss two main topics: how to recruit and interview undergraduates to work with you on your research project (~20 minutes total) and how to deal with challenging situations that might arise when working with an undergraduate (~one hour total). For example, how do you react to a student who wishes to change mentors? How do you motivate students in the lab? We will discuss several case studies as we explore these issues, and we will welcome ideas, questions, and issues from participants. The workshop will be held in BioLabs Room 2062 from 12:00 to 1:30 pm. Please bring a bag lunch; we will provide dessert. Ann Georgi, Undergraduate Research Advisor in Life Sciences, and Tamara Brenner, Assistant Director of Life Sciences Education, are facilitating the workshop series. --- Tamara Brenner, Ph.D. Assistant Director of Life Sciences Education Lecturer on Molecular and Cellular Biology Harvard University 16 Divinity Ave., Room 1087 Cambridge, MA 02138 (617) 384-7525 tamara_brenner(a)harvard.edu -- ******************************************** Semion K.

[Aspuru-Guzik group list] Fwd: [Users] Magellan cloud "bank accounts" in effect May 1

by Alan Aspuru-Guzik

Alán Aspuru-Guzik | Assistant Professor Harvard University | Department of Chemistry and Chemical Biology 12 Oxford Street, Room M113 | Cambridge, MA 02138 (617)-384-8188 | http://aspuru.chem.harvard.edu ---------- Forwarded message ---------- From: Francesca Verdier <fverdier(a)lbl.gov> Date: Thu, Apr 22, 2010 at 4:57 PM Subject: [Users] Magellan cloud "bank accounts" in effect May 1 To: users(a)nersc.gov Dear MPP users, NERSC has a cloud computing testbed, called Magellan, which is being used to evaluate cloud computing for scientific applications. We expect that starting in May, Magellan will be subdivided into smaller resource pools based on the requirements of different cloud testbeds and types of cloud research being done. All MPP users have access to the Magellan cloud nodes via the magellan queue from Carver. To account for cloud usage in NIM, new cloud repositories have been created. They usually have the name c###, where ### is the same as the ### part of your MPP repo name. The exception is if there are mp### and m### repos that share the same number - in this case the project with mp### will have a cloud repo with the name cd###. On May 1 charging will start for Carver. Also on May 1, NERSC will implement "Magellan bank accounts". Cloud repositories act as "Magellan bank accounts". These are not really allocations, but a way to ensure that all projects have fair access to the Magellan resources (when not being used for cloud research). Startup projects will have access to 15,000 MPP hours on Magellan; all other MPP projects will have access to a maximum of 200,000 MPP hours on Magellan. This is a maximum amount a project may use, but there is no commitment to deliver 200,000 hours to any one project. Both Carver and Magellan have a machine charge factor of 1.5. For information on the Magellan queues: http://www.nersc.gov/nusers/systems/carver/running_jobs/queues.php For information on MPP charging: http://www.nersc.gov/nusers/accounts/charging/mpp-charging.php Sincerely, -- Francesca Verdier email: fverdier(a)lbl.gov Department Head, NERSC Services phone: 510-486-7193 _______________________________________________ Users mailing list Users(a)nersc.gov

[Aspuru-Guzik group list] TODAY at 5 pm - Biodiversity, Ecology, and Global Change

by Center for the Environment

Ecological studies are the bridge that link biodiversity and global change issues. Please join us at the first Fall 2009 lecture in the Harvard University Center for the Environment and Bank of America series on Biodiversity, Ecology, and Global Change "Food Webs in River Networks: Algal Mediated Linkages of Rivers to Watershed and Nearshore Marine Ecosystems" Mary Power Professor, Integrative Biology, University of California Berkeley and Director, California Biodiversity Center TODAY 5:00 pm Harvard University Biolabs Lecture Hall 16 Divinity Ave Cambridge, MA We know too little about the spatial and temporal contexts of food webs to forecast how they will respond to environmental change. Interacting web members often derive their energy and constituent molecules from different environmental source areas ("resource sheds"). Better knowledge of consumers’ resource sheds would help us predict the population and food web consequences of spatially explicit environmental change. Organisms can also block resource fluxes to other consumers. Mapping out these "resource shadows" would help us understand consequences of population changes, invasions or losses of species. Resource fluxes and species performances and interactions are strongly influenced by topography and large vegetative structure. We have been using a "predictive mapping" approach to investigate how resource fluxes and food web regimes change with partially predictable changes in environmental controls down a river drainage network. In this talk, Mary Power will focus on regimes that control the production and fate of dominant primary producers (macroalgae, diatoms and cyanobacteria), and explore how predictive mapping might help us forecast ecosystem response, including algal-mediated linkages of river, aerial, and nearshore marine ecosystems, to changes in climate, land use, or biota. Mary Power’s lab at the University of California Berkeley investigates food webs in rivers and their watersheds. She is interested in how attributes of species influence their effects in food webs, and how species interactions change under different environmental regimes. Topics of current interest include: interplay of trophic dynamics with hydrologic and productivity regimes in rivers potential effects of climate change on food webs in rivers and meadows; impacts of invading exotic species food web links between rivers and their watersheds, specifically, the influence of river-derived insect production on terrestrial consumers in watersheds (spiders, lizards, bats); effects of fine bed sediments on juvenile steelhead and the food webs that support their growth changes in energy sources to food webs down drainage networks; landscape controls on stream metabolism, fluxes, and consumer-resource interactions; and the interplay between spatial fluxes of energy and nutrients to food webs and outcomes of local species interactions. The Biodiversity, Ecology, and Global Change lecture series is sponsored by the Harvard University Center for the Environment with generous support from Bank of America. This lecture is free and open to the public. A reception will follow in the Biolabs lobby.

[Aspuru-Guzik group list] [iic-colloquium] Colloquium April 28: "Visualization of Emergent Infectious Diseases" with Daniel Janies

by Rosalind Reid

You are cordially invited to next Wednesday's IIC Colloquium, to be given by Daniel Janies of Ohio State University. *********************** Large-Scale Visualization of Emergent Infectious Diseases April 28, 2010, 4:00 pm Room G-115, Maxwell Dworkin, 33 Oxford Street, Cambridge Daniel Janies, Associate Professor, Department of Biomedical Informatics, The Ohio State University Abstract Emerging infectious diseases are critical issues for public health. Rapid genomic sequencing, used in response to SARS and pandemic influenza, has become a primary method of diagnosing agents of infectious disease. In order to understand epidemics, however, one must incorporate more information. Sequence alignment and phylogenetics are fundamental tools for making sense of sequence data from emergent pathogens, enabling comparison to well-characterized pathogens. Both tools require significant computational equipment and user expertise. Janies’ group has developed web-based applications (e.g., http://supramap.osu.edu) that marry parallel sequence alignment and tree search with geographic visualization of the spread of pathogens and their genotypes and phenotypes. These applications reduce the expertise and nearly eliminate the computational equipment required for individuals to use sequence alignment and phylogenetics. They allow users to analyze large datasets of raw genetic sequence and phenotypes from pathogens and hosts in a geographic context, fostering interactions among diverse disciplines by providing a common framework for hypothesis generation and testing. Janies will discuss several multidisciplinary use cases, including analyses of host adaptation and drug resistance over space and time. About the Speaker Daniel Janies is an Associate Professor in the Department of Biomedical Informatics at The Ohio State University. He teaches computational analysis of genomic information for biomedical research and won an award for excellence in teaching and research at Ohio State in 2007. Dr. Janies' current research concerns the global spread of emergent infectious diseases. His work involves the development of software to map the spread of agents of infectious disease based on genomic and geographic data. The results are akin to weather maps for disease that allow public health scientists to visualize when and where pathogens jump from animals to humans and evolve to resist drugs. Dr. Janies' work has been the subject of local, national, and international press coverage. He was recently called to testify to the United States Senate and has advised the Pentagon, The White House Office of Medical Preparedness, and the United States Department of State on methods for disease surveillance. __________ Refreshments served at 3:45 pm __________ Mark your calendar for these upcoming talks: Monday, Apr. 26: SciGPU Seminar (noon, MD 323), Alice Quillen, University of Rochester Wednesday, May 5: Final IIC Colloquium, Jeannette M.
