Celeste Nelson, Associate Professor of Chemical and Biological Engineering, has taken on the role of CBE’s Director of Graduate Studies (DGS), effective July 1.  As DGS, Nelson oversees all aspects of CBE’s graduate program, interacting with both prospective and current graduate students.  Nelson takes the DGS reins from Athanassios Panagiotopoulos, who completed his second term of service as DGS on June 30.
In today’s issue of the journal Nature, a Letter describes unambiguous evidence for a liquid-liquid transition in a modern model of water—the ST2 model—at deep supercoolings, and even shows coexistence between the two liquid forms, which differ in density and average coordination number.  This behavior is thought to underpin several of the unusual properties of water at shallower undercoolings, such as the steep increases in compressibility, heat capacity, and thermal expa
Athanassios Z. Panagiotopoulos, Susan Dod Brown Professor of Chemical and Biological Engineering, has been elected as a Fellow of the American Institute of Chemical Engineers (AIChE), as approved by the AIChE Board of Directors at their March meeting.  Panagiotopoulos was recognized for his exceptional, sustained accomplishment in the creation of computational methods for the analysis and prediction of the behavior of complex fluids of interest to the chemical engineering community, and for
Each spring, the editors of the Journal of Chemical Physics select a few of the most innovative and influential articles published in the preceding year to highlight to the community as “Editors’ Choice”.  For 2012, one of the five highlighted articles in the “liquids, crystals, and glasses” area was “A Computational Investigation of the Phase Behavior and Capillary Sublimation of Water Confined Between Nanoscale Hydrophobic Plates”, from lead autho
Two CBE faculty—Ilhan Aksay and Athanassios Panagiotopoulos—were recently named Fellows of the American Association for the Advancement of Science (AAAS), in the AAAS’ Section on Engineering.  701 new Fellows were elected by the AAAS Council this year, spread across 24 sections.   Fellows are selected for their distinguished contributions to science and technology, and will recognized at a special Fellows Forum at the 2013 AAAS Annual Meeting (to be held in Bosto
This semester will be doubly memorable for William Holloway *12:  after successfully defending his Ph.D. thesis on April 24, he was notified yesterday that he has been selected as one of six recipients of a 2012 APGA Teaching Award from the Association of Princeton Graduate Alumni.  Holloway was recognized for his exceptional service as an Assistant in Instruction (AI) for CBE 246, “Thermodynamics”, taught by Professor Athanassios Panagiotopoulos in Spring 2011.  The a
Athanassios Panagiotopoulos, Susan Dod Brown Professor of Chemical and Biological Engineering, has been elected to the American Academy of Arts and Sciences, as announced in a press release issued today.  The Academy, founded in 1780 and headquartered in Cambridge, MA, is an independent policy research center that conducts multidisciplinary studies of complex and emerging problems.  This year, the Academy elected 220 new members, spanning the fields of Mathematical and Physical Science
Last week, first-year Chemical and Biological Engineering Ph.D. students Nathan Mahynski and Jonathan Robinson were awarded National Science Foundation (NSF) Graduate Research Fellowships in support of their research here. Mahynski is working with Professor Thanos Panagiotopoulos on “Self-Assembly of Polymer-Grafted Nanoparticles”, while Robinson is working with Professor Mark Brynildsen on “Improving Killing of Bacteria by Reactive Nitrogen Species”. Heartiest congratula
Microcin J25 is a small 21-residue antimicrobial peptide exhibiting an interesting "lasso" motif whereby the N-terminal glycine 1 is covalently bonded via a peptide bond to the glutamic acid 8 sidechain to form a loop through which the C-terminus is threaded and sterically locked in place by bulky aromatic groups either side of the ring.
Isolated n-alkane chains in water serve as useful model systems in which to study the role of hydrophobicity in protein folding.
Isolated n-alkane chains in water serve as useful model systems in which to study the role of hydrophobicity in protein folding. A nonlinear dimensionality reduction technique known as the diffusion map, was applied to long molecular dynamics simulations of n-alkane chains to systematically extract order parameters describing the slow, fundamental dynamics of the chain.
Crystal structures of spherical colloids: [i] binary mixture of large and small spheres, [ii] colloids in an external electric field, and [ii] binary mixture of oppositely charged colloids.
Postdoctoral fellow Antti-Pekka Hynninen and Professor Athanassios Panagiotopoulos have published a paper in Physical Review Letters that was selected as an “Editors‘ Suggestion” by the journal.
The research team of Professors Robert Prud'homme, Yannis Kevrekidis and Athanassios Panagiotopoulos has created particles that can deliver medicine deep into the lungs or infiltrate cancer cells while leaving normal ones alone.
Professor Athanassios Z. Panagiotopoulos has been named the Susan Dod Brown Professor of Chemical Engineering.
Professor Athanassios Panagiotopoulos has been elected to the National Academy of Engineering, "for the invention of the Gibbs ensemble method of molecular simulation of phase equilibrium and the development of computational techniques for studying complex fluids."
M. Scott Shell, a fourth-year graduate student working with Professors Debenedetti and Panagiotopoulos, has obtained a significant theoretical result on the properties of saddles in multidimensional potential energy surfaces (energy landscapes). The research, published January 23 in Physical Review Letters, has important implications for the theory of the glass transition.
