Atom downtime increased - 8pm Wednesday to 7:30am Thursday
by Harrington, Michael P 11 Apr '12

11 Apr '12

ECN has determined that they will need to shut down connections to Atom earlier than previously thought in order to proceed with the migration to the new server so you won't be able to save changes beginning at 8pm tonight and lasting until 7:30am Thursday. -Mike Harrington -----Original Message----- Michael P Sent: Monday, April 09, 2012 12:44 PM To: 'chmegrad(a)ecn.purdue.edu'; 'chme(a)ecn.purdue.edu' Subject: [Che-staff-list] New Server Install - Wednesday/Thursday of this week Hi, Atom, the main file and mail server for ChE will be replaced this week with a new, faster machine and storage system. As a part of this process ECN will need to 'lock down' the file system while the changeover is made. As a result, no one will be able to make any changes to files located on Atom between 12am and 7:30am on Thursday, April 12th. I will also post a note in the undergrad computer labs and a note will be posted in the MOTD (message of the day), however faculty or TA's might want to mention this to their students since some like to work late at night in the labs. -Mike Harrington ******************** Mike Harrington Computer Facilities Manager Chemical Engineering Purdue University 765-494-6428 mph(a)purdue.edu _______________________________________________ Che-staff-list mailing list Che-staff-list(a)ecn.purdue.edu https://engineering.purdue.edu/ECN/mailman/listinfo/che-staff-list

Purdue University School of Chemical Engineering GRADUATE SEMINAR SERIES Prof. James A. Dumesic University of Wisconsin - Madison "Strategies for Catalytic Conversion of Biomass to Hydrogen and Liquid Hydrocarbon Fuels" Tuesday, April 10, 2012 9:00-10:15 a.m. FRNY G140 Reception at 8:30 a.m. in FRNY Atrium Abstract: Environmental and political issues created by our dependence on fossil fuels, such as global warming and national security, combined with diminishing petroleum resources are causing our society to search for new renewable sources of energy and chemicals. We will introduce strategies for catalytic conversion of biomass-derived carbohydrates to produce H2 and CO2 for fuel cell applications, to generate H2 and CO for synthesis gas applications, or to produce liquid alkanes for transportation fuels. We will also present a cascade catalytic process for conversion of cellulose to gasoline or jet fuel, passing through the intermediate formation of levulinic acid and -valerolactone. Bio: James A. Dumesic earned his B.S. degree from UW-Madison and his M.S. and Ph.D. degrees from Stanford University, under the supervision of Professor Michel Boudart. Dumesic joined the Department of Chemical Engineering in 1976, and he is currently the Steenbock Chair in the College of Engineering and the Michel Boudart Professor of Chemical and Biological Engineering. Throughout his career, Dumesic has used spectroscopic, microcalorimetric, and reaction kinetics techniques to study the surface and dynamic properties of heterogeneous catalysts. Dumesic pioneered the field of microkinetic analysis, in which diverse information from experimental and theoretical studies is combined to elucidate the essential surface chemistry that controls catalyst performance. He has recently studied how aqueous-phase reforming of biomass-derived carbohydrates can be tailored to selectively produce H2 or directed to produce liquid alkanes. Most recently, he has been studying the use of levulinic acid and -valerolactone as biomass-derived platform chemicals for the production of fuels and chemicals. Dumesic has published more than 370 papers in peer-reviewed journals. Various information about research conducted by the Dumesic group can be found at the following link: http://www.engr.wisc.edu/che/ * * * * * * * * * * RESEARCH LECTURE James A. Dumesic Department of Chemical and Biological Engineering University of Wisconsin - Madison "Catalytic Conversion of Hemi-Cellulose and Cellulose to Fuels and Chemicals" Wednesday, April 11, 2012 11:30 am- 12:30 pm FRNY 3059 The conversion of lignocellulosic biomass to fuels and chemicals requires the effective utilization of the C5 and C6 sugars present in hemi-cellulose and cellulose, respectively. We will address how the hemi-cellulose fraction of lignocellulosic biomass can be converted to furfural and levulinic acid using biphasic reactors with alkylphenol solvents, and we will address the conversion of levulinic acid to gamma-valerolactone (GVL) in these solvents. In addition, we will show how various biomass-derived solvents can be used to extract levulinic acid produced by deconstruction of the cellulose in aqueous solutions of mineral acids. Finally, we will address the decarboxylation of GVL to produce butene over solid acid catalysts, combined with the oligomerization of butene to produce liquid transportation fuels.

From: May, Sandra M [mailto:smmay@purdue.edu] Sent: Friday, April 06, 2012 2:12 PM To: May, Sandra M Subject: BME Seminar announcement: April 11, 9:30AM, MJIS 1001 (teleconferenced to SL-220 at IUPUI) BME Seminar Series Wednesday, April 11, 2012 9:30-10:20am MJIS 1001 The seminar will be teleconferenced to SL-220 at IUPUI. Weldon School of Biomedical Engineering Purdue University Optical Diagnostics for Diseased and Engineered Tissues Irene Georgakoudi, PhD Associate Professor Department of Biomedical Engineering Tufts University Abstract: Development of functional engineered tissues has the potential to improve significantly current approaches aimed at repairing or replacing damaged tissues and organs. In addition, engineered tissues could serve as highly relevant and useful models for disease and for screening novel drugs and therapies. Methods to assess the development and function of these tissues are traditionally limited by their invasive and destructive nature. Our recent work demonstrates that optical spectroscopic imaging approaches can overcome these limitations and provide functional biochemical and organizational/structural information about tissues. We specifically aim to identify optical biomarkers associated with adipose and bone engineered tissue development and early cancer development using non-linear spectroscopic imaging methods that rely on endogenous fluorescence and scattering. Intrinsic two photon excited fluorescence (TPEF) has been used as the main platform to characterize tissue structure and function. Acquisition of emission spectra at multiple excitation wavelengths reveals that key aspects of the composition and organization of silk biomaterial scaffolds can be assessed using TPEF and second harmonic generation (SHG). Similar spectroscopic images also demonstrate that important biochemical and morphological parameters associated with stem cell differentiation can be extracted in two and three-dimensional cultures. Measurements performed on the same scaffolds over a period of six months illustrate that significant dynamic biochemical changes can be monitored to extract important insights in metabolic biochemical pathways. Biochemical and subtle, microscale organizational differences can also be detected as a function of depth within engineered normal and pre-cancerous epithelial tissues. Such non-invasive biomarkers could be ultimately used to develop improved diagnostics and to assess functional tissue development either in response to different stimuli or as quality controls prior to implantation. Bio: Irene Georgakoudi is an Associate Professor of Biomedical Engineering at Tufts University. She has been working on the use of lasers for therapeutic and diagnostic applications since her undergraduate years. She started as a physicist at Dartmouth College and continued her graduate studies in Biophysics at the University of Rochester. Her interests in spectroscopy and spectroscopic imaging using endogenous sources of contrast were founded during her postdoctoral years at the MIT Spectroscopy Lab. After working on the development of fluorescence-based in vivo flow cytometry while an Instructor at the Wellman Laboratories for Photomedicine at Massachusetts General Hospital/Harvard Medical School, she moved to Tufts in 2004. She is the author of several patents on the development and use of spectroscopy and imaging to characterize tissues or to detect specific populations of cells and has published numerous peer reviewed manuscripts, review articles and book chapters in these topics. She is the recipient of a Claflin Distinguished Scholar, an NSF Career, and an American Cancer Society Research Scholar award. She has served on the Board of Directors of the Optical Society of America ~BME Faculty Host: Young Kim~ ***Coffee and juice will be provided at West Lafayette***

VPN connection now required for all off-campus remote desktop sessions.
by Harrington, Michael P 09 Apr '12

09 Apr '12

Hi, Effective today you will need to run a VPN client in order to remotely connect to your office computer when off campus. This is a security measure that was announced last week by ITAP - not ECN. You will only be affected if you every connect to your office computer from home or elsewhere off campus to work on it remotely. This doesn't affect reading Purdue web pages, or using a web browser to read your email (like mymail or the exchange webmail reader). If you need to remotely connect and have not already installed the VPN client you will need to go to the following page and follow the directions: http://www.itap.purdue.edu/connections/vpn/index.cfm If you have issues with this I would suggest you first contact ITAP for help since they are the ones that supply and maintain the VPN software. They can be reached at itap(a)purdue.edu or by calling 494-4000. One note, if you have to manually install the VPN software like I did, you will need to supply the VPN connection information - you want to tell the program to connect to webvpn.purdue.edu -Mike ******************** Mike Harrington Computer Facilities Manager Chemical Engineering Purdue University 765-494-6428 mph(a)purdue.edu
