Dear All, For those who will attend the AIChE meeting... Attached is the invitation to our School's reception on Monday evening. Pl attend, if you can. Owing to health issues, I'll miss the AIChE annual meeting this year. I've attended these meetings since 1976 - this would have been my 40th in a row! Dr. Sang Kim and Cristina Farmus have kindly agreed to serve as hosts for our reception. I wish you a productive and enjoyable meeting! Arvind Varma R. Games Slayter Distinguished Professor Jay and Cynthia Ihlenfeld Head of Chemical Engineering Purdue University

Construction update Nov 11-20, FYI
by Farmus, Cristina D 05 Nov '15

05 Nov '15

Another crane lift operation will take place between November 9-20, 2015. This will not require building closure due to the lift taking place over the construction area. This activity will not affect building operations and all entrances will remain open. The next crane lift will take place during the Christmas break and will require the addition to be closed.

[cid:image003.png@01D11716.BB941AE0]<https://engineering.purdue.edu/ChE> Purdue University School of Chemical Engineering GRADUATE SEMINAR SERIES Dr. Jeremiah Zartman Department of Chemical and Biomolecular Engineering University Notre Dame "Engineering Approaches to Investigate the Regulation of Epithelial Growth and Homeostasis" Tuesday, November 17 2015 3:00 - 4:15 p.m. FRNY G140 Reception at 2:30 p.m. in Henson Atrium Abstract: The revolution in molecular biology within the last few decades has led to the identification of multiple, diverse inputs into the mechanisms governing the measurement and regulation of organ size. In general, organ size and homeostasis is controlled by both intrinsic, genetic mechanisms as well as extrinsic, physiological factors. Examples of the former include the spatiotemporal regulation of organ size by morphogen gradients, and instances of the latter include the regulation of organ development by endocrine hormones, oxygen availability, nutritional status and the mechanics of the microenvironment. However, integrated model platforms, either of in vitro experimental systems amenable to high- resolution imaging or in silico computational models that incorporate both extrinsic and intrinsic mechanisms are lacking. Here, I will discuss collaborative efforts to bridge the gap between traditional assays employed in developmental biology and computational models through quantitative approaches. These interdisciplinary efforts are being applied to develop integrated models of epithelial growth and homeostasis in the larval wing imaginal disc of the fruit fly, due to the wealth of previous genetic knowledge for the system. In particular, I will discuss our current understanding of how intrinsic and extrinsic factors impact the spatiotemporal dynamics and possible functional roles of calcium signaling in development and homeostasis using a combination of microfluidics devices, organ culture and computational modeling of signal transduction. An integrated model of intrinsic and extrinsic growth control is expected to provide greater insight into how cells communicate to coordinate tissue-level responses. Bio: Dr. Jeremiah Zartman received his Bachelors degree from the University of Colorado at Boulder with a dual major in Chemical Engineering and Engineering Physics in 2004. In 2009 he obtained his Ph.D. in Chemical and Biomolecular Engineering under the supervision of Prof. Stanislav Shvartsman at Princeton University as a Princeton Hertz Fellow. From 2009-2011, he worked as post-doctoral research in the lab of Prof. Konrad Basler, University of Zurich, in Molecular Life Sciences as an EMBO Long-term Post-doctoral Fellow. Since 2012, Dr. Zartman has led a research group at the University of Notre Dame. The lab focuses on the integration of computational and experimental approaches toward the development and function of multicellular systems as well as the development of advanced in vivo screening approaches for target discovery in cancer and regenerative medicine.

Doyle, III John A. Paulson Dean Harvard's Paulson School of Engineering & Applied Sciences Harvard University "Engineering the Artificial Pancreas" Tuesday, November 3, 2015 3:00 - 4:15 p.m. FRNY G140 Reception at 2:30 p.m. in Henson Atrium Abstract: Type 1 diabetes mellitus (T1DM) is a chronic autoimmune disease affecting approximately 35 million individuals world-wide, with associated annual healthcare costs in the US estimated to be approximately $15 billion. Current treatment requires either multiple daily insulin injections or continuous subcutaneous (SC) insulin infusion (CSII) delivered via an insulin infusion pump. Both treatment modes necessitate frequent blood glucose measurements to determine the daily insulin requirements for maintaining near-normal blood glucose levels. Twenty years ago, in the School of Chemical Engineering at Purdue, I began a research quest to design an artificial pancreas for patients with type 1 diabetes mellitus (T1DM). The closed-loop concept consisted of an insulin syringe, a blood glucose analyzer, and a transmitter. In the ensuing years, a number of theoretical research studies were performed with numerical simulations to demonstrate the relevance of advanced process control design to the artificial pancreas, with delivery algorithms ranging from simple PID, to H-infinity, to model predictive control. With the advent of continuous glucose sensing, which reports interstitial glucose concentrations approximately every minute, and the development of hardware and algorithms to communicate with and control insulin pumps, the vision of closed-loop control of blood glucose is approaching a reality. In the last 10 years, our research group has been working with medical doctors on clinical demonstrations of feedback control algorithms for the artificial pancreas. In this talk, I will outline the difficulties inherent in controlling physiological variables, the challenges with regulatory approval of such devices, and will describe a number of process systems engineering algorithms we have tested in clinical experiments for the artificial pancreas. Our algorithmic developments have focused on variations of model predictive control, including customized patient models and asymmetric cost functions to deal with hyper- and hypo-glycemic excursions. The latest results from longer term clinical trials, including studies with adolescents, will be reported. Bio: Frank Doyle is the John A.

Caitlin Schram Dissertation Defense, Thursday, October 29th, at 3:00 p.m. in FRNY G060A
by Green, Corwin S 23 Oct '15

23 Oct '15

This e-mail is to announce that Caitlin Schram will be defending her dissertation, Impact of Polymers on the Solution Crystal Growth Rate of a Poorly Water-Soluble Active Pharmaceutical Ingredient, on Thursday, October 29, at 3:00 p.m. in FRNY G060A. The dissertation is directed by Dr. Beaudoin, and the abstract is below. All are welcome to attend. Abstract: Poor aqueous solubility is a major impediment to the oral delivery of over 75% of pharmaceutical compounds currently under development. The bioavailability of these compounds can be enhanced with the use of supersaturating dosage forms, due to their high flux rates across the gastrointestinal tract membrane. However, the success of this strategy hinges on the ability to inhibit crystallization of the supersaturated drug solutions. Polymers can be used to inhibit crystallization and prolong supersaturation, however the mechanisms of polymer inhibition are not yet fully understood. Therefore it is desirable to understand the attributes that render a polymer effective. In this work, the crystal growth rate of a poorly soluble pharmaceutical compound, felodipine, was measured in the presence of various polymers. The growth rate studies were performed using a rotating disk apparatus so that the growth kinetics could be controlled and mathematically modeled. It was found that both polymer ionization state and polymer hydrophobicity greatly impacted polymer effectiveness. Investigation of these systems with atomic force microscopy (AFM) revealed that these properties significantly impacted adsorbed polymer conformation. The polymers that adsorbed in an extended chain conformation were able to achieve a higher degree of surface coverage than those that adsorbed in a coiled globule formation. The surface coverage was found to directly correlate to polymer effectiveness. By modeling this correlation using the Kubota-Mullin model, polymer effectiveness could be predicted when surface coverage was known. This research also assessed the ability of a polymer to impact crystal morphology. It was found that when polymers were present during crystal evolution from an amorphous melt, they were able to impact the size and shape of the resulting crystals. This in turn influenced the rate of crystal growth from supersaturated solutions.
