    by Peter Rony and Karl Schnelle

    Welcome to the Winter 2011 issue of CAST Communications. Sometime last year, we learned that approximately 15% of the CAST Division members attend the Fall Annual AIChE meeting. This figure of 15% is true for the other AIChE Divisions, as well. Therefore, it is with great pride and enthusiasm that the Editors present you with this Fall 2011 issue, a truly historic issue of CAST Communications. This online newsletter is an important value-added benefit of being a member of the Division.

    First, we wish to congratulate our new members of the CAST Division Executive Committee: Professor Marianthi G. Ierapetritou, our Second Vice-Chair; and both Professor Christos T. Maravelias and Dr. John P. Congalidis, who are the 2012-2014 CAST Directors.

    Second, we honor the winner of the Directors’ Award for the Best Poster at the 2011 AIChE Annual Meeting - Janna Martinek, et al - and the honorable mention awardees – Yijie Gao and Fani Boukovala, et al. Please take the time to click on the links and view the PDF files of their impressive posters.

    CAST Division Award-Lecture-Introducer-Extraordinaire Wayne Bequette has outdone himself with his introduction to our 2011 Computing-in-Chemical-Engineering Award winner Paul I. Barton. Wayne has provided, for posterity, the photos and dates of our 34 award winners. Please focus your attention on this outstanding group of chemical engineering scholars. To help you with this task, your homework is to match photos with winners. There are 33 awardee names and only 30 photos.

    As is tradition, we present the complete award lecture by honoree, Paul I. Barton on Energy Systems Engineering.

    In addition, this issue contains several other important announcements. For example, CAST Student Travel Grants were given to five, very deserving students for the Annual AIChE Meeting. This is now the fifth year for these grants. Also, photos of the 2011 CAST poster session and awards dinners are included in this issue. Please have a look below!

    Your Editor has been with CAST Communications since 1986. During these 25 years, the Editors have made several transitions – from (a) a newsletter that summarized CAST Division session titles, to (b) a printed newsletter that provided articles, communications, and announcements, and finally (c) an online newsletter that included PDF files of session presentations, articles, poster presentations, award lecture introductions, and award presentations at the CAST Division dinner in November. During these 25 years we have succeeded in eliminating the expense associated with printing and mailing the newsletter from the AIChE New York office and also injecting wonderful color images into the newsletter. The Editor thanks the Associate Editor, Karl Schnelle, for his skillful work as producer of the online newsletter. Along the way, the newsletter has won several Max Isaacs awards for outstanding AICHE Division newsletter.

    And the Quote of the Day is by Dom Pérignon.


    NOTE: The following presentations were given at the CAST Plenary Session at the 2011 Annual Meeting of AIChE in Minneapolis, MN.

    Multiscale Modeling and Control of Thin Film Surface Morphology and Microstructure
    by Jianqiao Huang, Xinyu Zhang, Gangshi Hu, Gerassimos Orkoulas, and Panagiotis D. Christodes

    This work focuses on modeling and control of aggregate thin film surface morphology for improved light trapping using a patterned deposition rate profile. The dynamics of the evolution of the thin film surface height profile are modeled by an Edwards-Wilkinson-type equation (a second-order stochastic partial differential equation) in two spatial dimensions. The thin film surface morphology is characterized in terms of aggregate surface roughness and surface slope. These variables are computed with respect to appropriate visible light-relevant characteristic length scales and defined as the root-mean-squares of height deviation and slope of aggregate surface height profiles, respectively.

    Analytical solutions of the expected aggregate surface roughness and surface slope are obtained by solving the Edwards-Wilkinson equation and are used in the controller design. The model parameters of the Edwards-Wilkinson equation can be estimated from kinetic Monte-Carlo simulations using a novel parameter estimation procedure. This parameter dependence on the deposition rate is used in the formulation of the predictive controller to predict the influence of the control action on the surface roughness and slope at the end of the growth process. The cost function of the controller involves penalties on both aggregate surface roughness and mean slope from set-point values as well as constraints on the magnitude and rate of change of the control action. The controller is applied to the two-dimensional Edwards-Wilkinson equation. Simulation results show that the proposed controller successfully regulates aggregate surface roughness and slope to set-point values at the end of the deposition that yield desired levels of thin film reflectance and transmittance levels.

    Computer Aided Solvent Selection and Design Framework
    by Igor Mitrofanov, Elisa Conte, Gürkan Sin, and Rafiqul Gani

    Solvents are widely used as a reaction medium, as a reactant or as carrier at some stages of the manufacturing chain in products from the chemical, fine chemical, pharmaceutical, food, and agrochemical industries. Solvent are either required for processing after which they are removed or they are part of the final product formulation. Therefore, solvents are playing an important role in product synthesis and formulation, product delivery, separation processes etc [1]. On the other hand, solvent selection and design is a complex problem, which requires decision making in several levels for indentifying the best candidates depending on different multi-objective criteria namely environment, health, safety, process feasibility and economics.

    One of the criteria of solvent selection is the environmental impact because of the excessive consumption and utilization in a wide range of industries, millions of tons solvents have to be wasted every year [2]. Therefore, it becomes important to minimize and optimize the use of organic solvents as much as possible, to satisfy the “Green Chemistry Principles” [3]. Another challenge is that currently solvent selection relies very much on previous experiences, trial and error with different solvent candidates. Such heuristic approach while valuable on their own, however arguably are not fit to deal with a complex multi-criteria optimization and search problem, which is the case for solvent selection.

    Therefore the purpose of this contribution is to develop a systematic framework and implement it as software for selection and design of solvents for many applications including organic synthesis, complex reaction systems and solvent-based separations. The solvent selection framework is based on a combination of knowledge from industrial practice and computer-aided tools and methods for property prediction and computer-aided molecular design (CAMD) principles. This framework is applicable for solvent selection and design in product design as well as process design.

    Dom Pérignon may get all the credit for Champagne, but wiki says it was actually an English scientist and glass maker, Christopher Merret, who published a paper in 1662 concerning secondary fermentation to produce the bubbles. Have a great New Years!!!
