Safety policies specific to FRNY
by Nagy, Gabriela 05 Mar '15

05 Mar '15

Hello Everyone, The ChE Safety Committee developed a ChE Safety Policies document to address some of the safety concerns in our School community. These policies are in addition to the safety rules applicable at University level and to those found in the Purdue Chemical Hygiene Plan and are enforced throughout our building. More stringent rules, for a specific work area, may be put in place by our Faculty. The document is now posted on our website: https://engineering.purdue.edu/ChE/AboutUs/Safety.html , under the Safety Policies Specific to Forney Hall section. Please find attached a copy of this document, which will be updated as necessary. The official version of this document will only be maintained online and the updates will be communicated to the School. The Safety Committee will place signs identifying the areas in our building where the "One glove policy" applies. Should you have questions or concerns, please let me, or any other member of the safety committee know. The list of ChE Safety Committee members is posted online, at https://engineering.purdue.edu/ChE/AboutUs/Safety.html . Thank you for your commitment to safety! Sincerely, Gabriela On behalf of ChE Safety Committee __________________ Gabriela Nagy, PhD Industrial Education Director ChE Safety Committee Chair School of Chemical Engineering Room FRNY G051 Purdue University Tel: (765)-496-1710 E-mail: nagyg(a)purdue.edu<mailto:nagyg@purdue.edu>

Graduate Seminar Series- Dr Jeffrey Varner -March 5
by Ewing, Virginia G 04 Mar '15

04 Mar '15

[blackwelder] School of Chemical Engineering Graduate seminar series Prof. Jeffrey D. Varner Chemical and Biomolecular Engineering Cornell University "Modeling and Analysis of Intracellular Biochemical Network Architectures" Thursday, March 5, 2015 9:00-10:15 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: Biochemical networks frequently contain a large number of coupled chemical reactions and complex architectural features such as redundancy, feedback and crosstalk. While this complexity ensures robustness, it also complicates the reprogramming of network function. The objective of our research is to develop mathematical modeling tools to rationally reprogram intracellular carbon, energy and information flows. Toward our objective, we developed computational tools to automate model generation, identification and analysis. These tools, together with our growing database of network components, have allowed us to construct and test several large-scale human signaling models (200 - 1000 molecular components) on a rapid time-scale. In this study, we'll discuss examples which demonstrate these tools. First, we'll discuss a model of the signaling program driving All-Trans Retinoic Acid (ATRA) induced differentiation in HL-60 cells. HL-60 is a well established albeit simplified model of hematopoietic differentiation that we have used to understand the basic architecture of this important program. From our modeling studies, we identified a minimal memory circuit potentially responsible for the pre-commitment memory observed in RA-induced HL-60 differentiation. Second, we'll discuss another important differentiation program, the epithelial to mesenchymal transition (EMT). Decades of work has identified the critical signaling pathways controlling EMT. However, each of these pathways is responsive to multiple ligands and display a high degree of crosstalk. We showed, using a combined computational and experimental strategy, that pathway crosstalk between VEGFA and TGF-B1/2 signaling is responsible for modulating the phenotypic balance between the epithelial and mesenchymal state for a variety of cell types. Interestingly, the EMT program, although different in function, shares many common architectural features with the HL-60 program, suggesting conserved but highly adaptable motifs. Lastly, we'll discuss on-going work in the lab exploring the behavior of both whole cell and cell free metabolic networks, and present strategies for building genome scale cell free metabolic models. Bio: Jeffrey Varner holds a Ph.D degree in Chemical Engineering from Purdue University where he explored modeling and analysis of metabolic networks in the lab of Prof. Ramkrishna. After a postdoc in the Department of Biology at the ETH-Zurich under the direction of Jay Bailey and a research position at Genencor International Inc, Palo Alto, CA, Prof. Varner joined the faculty of the Chemical and Biomolecular Engineering department at Cornell University as an Assistant Professor in 2006. In the fall of 2011, Prof. Varner was promoted to Associate Professor with tenure. The Varnerlab is interested in modeling and analysis of signal transduction and metabolic networks.

FW: REMINDER – Exchange Maintenance on Feb 28th starting at 12:00pm
by Harrington, Michael P 27 Feb '15

27 Feb '15

Please note this and expect intermittent connectivity issues tomorrow if you have an Exchange account. This applies to many (not all) ChE Faculty and most ChE Staff. -Mike Harrington From: ITaP Messaging Sent: Friday, February 27, 2015 4:45 PM To: Exchange Users Subject: REMINDER – Exchange Maintenance on Feb 28th starting at 12:00pm All, This is a reminder that on Saturday February 28th, the Exchange Administrators will be performing a scheduled upgrade starting at 12:00pm. During this upgrade, customers will see intermittent connectivity with their email clients as the servers are being worked on. Clients include Outlook, OWA, Thunderbird, Mobile Devices, etc. The Exchange Administrators will be finished with their upgrades by 6:00pm, however, there is additional Windows Server updates that will be taking place afterwards. This patching takes place monthly, so the service interruptions will be no different than our customers normally see each month. If there are any questions, please let us know. Thanks. Aaron Sprout ITaP Messaging Administrator

Graduate Seminar Series ChE- Prof Perla Balbuena- March 10
by McDaniel, Emily M 25 Feb '15

25 Feb '15

[blackwelder] School of Chemical Engineering Graduate seminar series Prof. Perla Balbuena Dept. of Chemical Engineering Texas A&M Univeristy "Modeling Interfacial Phenomena in Lithium-Ion and Lithium-Sulfur Batteries" March 10, 2015 9:00-10:15 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: Interfacial phenomena are present in many chemical engineering problems. Here we focus on solid-electrolyte interfaces where not only mass and heat transfer but also chemical reactions may occur. To understand the details, we will use a "theoretical microscope" based on first-principles (density functional theory) analyses. We will discuss electron transfer reactions occurring from electrodes of lithium-ion and lithium-sulfur batteries causing the reduction of organic solvents and salts used as electrolytes. The impact of these phenomena on battery performance will be addressed. Bio: Prof. Balbuena received a BS degree at Universidad Tecnologica Nacional Argentina, MS from University of Pennsylvania, and PhD from the University of Texas at Austin, all in Chemical Engineering. She has been Assistant and Associate Professor at the University of South Carolina and since 2004 she is a Professor of Chemical Engineering and Professor of Materials Science and Engineering at Texas A&M University. Her work focuses on first principles analysis and design of materials. Recent research includes applications to fuel cell electrocatalysis, interfacial phenomena in batteries, shale gas thermodynamics, and separation of gas mixtures.
