21 Apr '14

Hello ChE Grad Students, Dr. Howard Stone from Princeton will be giving the Seminar tomorrow morning, and there will be an informal grad student meeting with him from 3:00 to 3:30 in 2142. Please let me know if you'd like to attend, and I'll put your name on the list. You do get a free Seminar pass if you go to this meeting. Best, Katie Catherine Field, Ph.D. Graduate Program Administrator/Counselor School of Chemical Engineering Forney Hall of Chemical Engineering, Room 1051 480 Stadium Mall Drive West Lafayette, Indiana 47907-2100 Phone: 765-494-4057 Fax: 765-494-0805 Email: field2(a)purdue.edu<mailto:field2@purdue.edu> Website: www.engineering.purdue.edu/ChE<http://www.engineering.purdue.edu/ChE> From: Che-staff-list [mailto:che-staff-list-bounces@ecn.purdue.edu] On Behalf Of Ewing, Virginia G Sent: Monday, April 21, 2014 4:32 PM To: 'chme(a)ecn.purdue.edu'; 'engfaculty-list(a)ecn.purdue.edu' Subject: [Che-staff-list] Graduate Seminar Series- Prof Howard Stone 4/22 Purdue University School of Chemical Engineering Graduate seminar series Prof. Howard Stone Dept. of Mechanical & Aerospace Engineering Princeton University "Elementary channel flows with surprising responses: (i) Biofilms and flow and (ii) Trapping of bubbles in stagnation point flows" April 22, 2014 9:00-10:20 a.m. FRNY G140 Reception at 8:30 a.m. in Henson Atrium Abstract: In this talk I describe two distinct problems that we have studied where seemingly modest variations in an elementary channel flow produce new effects. First, we investigate some influences of flow on biofilms. In particular, we identify the formation of biofilm streamers, which are filaments of biofilm extended along the central region of a channel flow, and show how these filaments are capable of causing catastrophic disruption and clogging of industrial, environmental and medical flow systems. We present a mathematical model to rationalize the rapid growth of the streamer. As we shall show, clogging occurs from the "inside-out" rather than form the "outside-in". Second we consider flow in a T-junction, which is perhaps the most common element in many piping systems. The flows are laminar but have high Reynolds numbers, typically Re=100-1000. It seems obvious that any particles in the fluid that enter the T-junction will leave following the one of the two main flow channels. Nevertheless, we report experiments that document that bubbles and other low density objects can be trapped at the bifurcation. The trapping leads to the steady accumulation of bubbles that can form stable chain-like aggregates in the presence, for example, of surfactants, or give rise to a growth due to coalescence. Our three-dimensional numerical simulations rationalize the mechanism behind this phenomenon. Bio: Professor Howard A. Stone received the Bachelor of Science degree in Chemical Engineering from the University of California at Davis in 1982 and the PhD in Chemical Engineering from Caltech in 1988. Following a postdoctoral year in the Department of Applied Mathematics and Theoretical Physics at the University of Cambridge, in 1989 Howard joined the faculty of the (now) School of Engineering and Applied Sciences at Harvard University, where he eventually became the Vicky Joseph Professor of Engineering and Applied Mathematics. In July 2009 Howard moved to Princeton University where he is Donald R. Dixon '69 and Elizabeth W. Dixon Professor in Mechanical and Aerospace Engineering Professor Stone's research interests are in fluid dynamics, especially as they arise in research and applications at the interface of engineering, chemistry, physics, and biology. He received the NSF Presidential Young Investigator Award, is a Fellow of the American Physical Society (APS), and is past Chair of the Division of Fluid Dynamics of the APS. He is currently on the editorial or advisory boards of New Journal of Physics, Physics of Fluids, Langmuir, Philosophical Transactions of the Royal Society, Soft Matter, and is co-editor the (new) Soft Matter Book Series. He is the first recipient of the G.K. Batchelor Prize in Fluid Dynamics, which was awarded in August 2008. In 2009 he was elected to the National Academy of Engineering. In 2011 he was elected to the American Academy of Arts and Sciences.

Dear Colleagues, I am delighted to inform about 2 Purdue recognitions received by our School faculty yesterday. First, Bryan Boudouris has received a 2014-15 Teaching for Tomorrow Award, where he's one of nine "junior" faculty matched with three highly accomplished and experienced faculty who will, over the next year, address important topics and experiences related to teaching and student learning. In recognition of his past accomplishments and future promise, he'll be awarded $1,500 in discretionary funds. Second, Rakesh Agrawal has been selected as one of the 2014 recipients of the Morrill Award, Purdue's highest career achievement recognition for a faculty member. He is cited as being among a select group of awardees the Morrill Award Committee judged to have excelled in all roles as a Professor at a land-grant research university. The committee saw clear synergies among his roles as teacher, scholar and engaged professor, and was also impressed with the impact of his work on society. The Morrill Award comes with a $30,000 prize which may be used as discretionary funds or salary supplements. Pl join me in congratulating Bryan and Rakesh for their terrific awards, which also bring recognition to our School! With best wishes, Arvind

Faculty Seminar - Dr. Enrique Iglesia 4/16
by Ewing, Virginia G 15 Apr '14

15 Apr '14

Purdue University School of Chemical Engineering FACULTY SEMINAR Prof. Enrique Iglesia Dept. of Chemical and Biomolecular Engineering University of California, Berkeley Nanoparticles and Nanospaces: The Catalysis Toolbox Wednesday, April 16, 2014 11:30am - 12:30 pm FRNY G140 Abstract. Chemical reactions occur at the smallest of dimensions, where bonds cleave and form. The size of molecules, catalytic structures, and their containers matters at this nanometer scale. Diversity and specificity in catalysis exploit size to extend the properties of elements from those in their bulk state. Reactivity in metals and oxides changes markedly as coordination and electronic environment at exposed surfaces vary with cluster size. Low-coordination atoms on small clusters stabilize transition states for reactions limited by bond cleavage on bare surfaces. Such atoms, however, also stabilize chemisorbed reactants, making small clusters less reactive when steps require such species. On semiconductors, such as oxides and sulfides, the charge delocalization required at transition states leads to an intrinsic link between reactivity and electronic/optical properties. Confinement of catalytic structures within small voids preserves their size, protects them from impurities, and allows preferential access by certain reactants, while also selecting specific transition states, thus conferring enzyme-like specificity to chemical catalysis.
