“Some Uses and Misuses of Equilibrium Thermodynamics”
Wednesday, March 20, 2019
3:00 pm, Wu and Chen Auditorium
Reception to follow – Lubin Galleria, Singh Center
Abstract: We will discuss a number of legitimate and of wrongful applications of the Second Law of Thermodynamics, in particular, in the screening of chemical processes. We consider how ideas of equilibrium thermodynamics and statistical mechanics can be of value in some non-equilibrium situations, particularly in the cases of very slow diffusion and reaction.

Abstract: As the pipelines of innovators continue to diversify across modalities, every company will face the challenge of both building needed capabilities for all modalities while maintaining their existing capacities and capabilities dedicated to any particular modality completely consumed by the current portfolio. In addition to this diversification, the productivity of more mature modality platforms is increasing significantly, driving current facilities to be under-utilized or in need of redesign. This inflection point will create the need for different partnership models among innovator companies and between innovator companies and contract manufacturing and laboratory organizations. Since owning everything will be a significant burden, the onus will be on each company to clearly delineate what it can manage and what it can access through these partnerships. In this talk we highlight progress of Biogen’s manufacturing platforms for anti-sense oligo nucleotides and for monoclonal antibodies given these realities.

Abstract: Chemical engineers have been at the forefront of the invention of computational algorithms enabling the molecular-based analysis of complex scientific and technical questions. Building upon a solid foundation in thermodynamics and statistical mechanics, these methods allow detailed microscopic scrutiny of a wide range of problems of interest in modern chemical engineering, thereby providing fundamental understanding and facilitating rational design. Dr. Debenedetti will illustrate the insights that can be gained from theory and computation by drawing on three examples from his own research: molecular-scale hydration phenomena, the behavior of proteins at low temperatures, and ice formation in the atmosphere. The implications of this work include pharmaceutical formulations, weather forecasting and the design of water-repellent surfaces.

2015: Nigel Seaton
Principal and Vice-Chancellor
Wednesday, April 1, 2015
Abstract: British and American universities have common roots. These go back to the Enlightenment and beyond for older schools, such as Penn and Edinburgh, my other alma mater. More recently, there is a shared heritage in the development of educational opportunities for “the working man” towards the end of the 19th century (the working woman had rather longer to wait) through the land-grant institutions in the US, and corresponding – though more incremental – reforms in the UK.
Today, mid-way through the second decade of the 21st Century, there is still much that connects us. We have a shared understanding of the relationship between the educational experience we offer and the values of the liberal democracies we inhabit – though the frontiers of liberal education require, as always, to be patrolled. During the 20th century, we developed ways of working that combined – that is, reconciled, or at least managed the tension between – competing concepts of the university as a community of scholars and as an economic enterprise. And both countries delivered, with the US taking a lead through the GI Bill, a massive expansion of higher education, which sustained economic development, made possible the knowledge economy and – most fundamentally – transformed hundreds of millions of lives.
In the last few decades of the 20th century, the two systems began to diverge in significant ways, reflecting evolving concepts of the role of the state, differences in the status of university faculty as a professional group (tenure was abolished in the UK in 1987) and differing public expectations. This divergence continues today, in tension with our shared cultural values and an increasingly interconnected market for the “outputs” of higher education – notably in research.
My presentation will be a tour through this territory. On this tour, we will be looking through some lenses. Some will be telescopic (such as higher-education policy) and some microscopic (academic chemical engineering). Some will be more personal than others. As with all tours, I hope to inform, perhaps to entertain a little, and to generate some interesting discussion.
Biography: Professor Nigel Seaton began his academic career at the University of Edinburgh, where he gained a BSc in Chemical Engineering in 1982, having spent his junior year as an exchange student at the University of Pennsylvania. He returned to Penn to do a PhD in Chemical Engineering, working with Eduardo Glandt on the statistical mechanics of colloidal dispersions.
After completing his PhD, Professor Seaton returned to the UK and worked initially as a research engineer in the oil industry, mostly with BP. In 1989 he resumed his academic career on his appointment as a Lecturer in Chemical Engineering at the University of Cambridge, where he was also a Fellow of Clare College. He was a visiting professor at Cornell University in the academic year 1996-97.
In 1997, Professor Seaton returned to the University of Edinburgh as Professor of Interfacial Engineering. Between 1998 and 2007, he was successively Head of the School of Chemical Engineering, Head of the Division of Engineering, Head of the Institute for Materials and Processes, and Dean of Undergraduate Studies in the College of Science and Engineering. In 2007, he became a Vice-Principal of the University of Edinburgh and from 2008 to 2012 served as Senior Deputy Vice-Chancellor at the University of Surrey.
In 2012, Professor Seaton was appointed Principal of Abertay University.
Nigel Seaton’s research interests are in the area of adsorption and transport in porous materials, focusing particularly on the development of methods for material design, and on the prediction of material performance in industrial applications.
Professor Seaton is a Fellow of the Royal Academy of Engineering, and a Fellow of the Institution of Chemical Engineers.

Pioneer of “next-gen” sequencing; Founder of CuraGen, 454 Life Sciences, and Ion Torrent
“The Development of High-Speed DNA Sequencing: Neanderthal, Moore and You”
Wednesday, April 2, 2014
Abstract: Since Watson and Crick’s 1953 landmark discovery that biological information was encoded in DNA as a sequence of chemical building-block “letters”, developing technology for reading—or “sequencing”—this chemical code has been fundamental to advances in biology and medicine. Techniques that first enabled this were invented by Sanger in 1978, and were taken to massively parallel form by 454 Life Sciences in 2003 (1). This ushered in the current or “next-gen” era of genome sequencing technologies for research, medicine, and the emerging field of Genomic Personalized Medicine, in which healthcare is more fully informed by the individuals’ personal genetic makeup.
Five years after the Human Genome Project, very little had changed in sequencing technology until my team at 454 Life Sciences pioneered and was first to commercialize sample preparation by limiting dilution, and massively parallel sequencing on a solid substrate. These central ideas — inspired by the “monolithic idea” of Robert Noyce and Jack Kilby – made large-scale sequencing affordable, and became the foundation of all next-gen sequencing technologies.
454 made it possible to sequence personal genomes – Dr. James D. Watson – as well as enabled a host of other firsts – The Neanderthal Genome, demonstrating genetic mixing with modern humans; the first deep sequencing of samples from cancer patients to better inform drug selection; uncovering a virus killing transplant patients; sequencing the extinct wooly mammoth and elucidated the extent of individual human variation, work recognized by Science magazine as the breakthrough of the year for 2007. The New England Journal described 454’s sequencing innovation as “The New Age of Molecular Diagnostics for Microbial Agents.”
If Sanger was the mainframe of sequencing, 454 was the minicomputer – smaller and faster and establishing the key guiding technical principals. To further scale, reduce cost and democratize the technology I turned back to the developments of Noyce and Moore, and developed the first semiconductor based, post-light, sequencing technology to make it truly personal. We demonstrated this by sequencing the genome of Gordon Moore of Moore’s law fame (2).
This technology, in the form of a single-use, disposable chip, is the core of the Ion Torrent DNA sequencing platform. This is the first semiconductor device capable of performing DNA sequencing, and the use of a scalable CMOS chip architecture allows for radical levels of economic scaling, and convenient new formats (from desktop to portable).

Biography: Dr. Jonathan Rothberg is best known for inventing high-speed, massively parallel DNA sequencing. He subsequently founded 454 Life Sciences, bringing to market the first new method for sequencing genomes since Sanger and Gilbert won the Nobel Prize in 1980. He led the effort to complete the first sequence of an individual human genome (James D. Watson’s genome). He also initiated the Neanderthal Genome Project, in collaboration with Dr. Svante Paabo. Under his tenure, 454 Life Sciences worked with collaborators to crack the mystery behind the disappearance of the honey bee, uncover a new virus killing transplant patients, and elucidate the extent of individual human variation—work recognized by Science magazine as the breakthrough of the year for 2007. The New England Journal described Dr. Rothberg’s sequencing innovation as “The New Age of Molecular Diagnostics for Microbial Agents.” Science magazine called it one of the top 10 breakthroughs for 2008. His contribution to sequencing, include both the first non-bacterial cloning systems (cloning by limited dilution), as well as the first massively parallel DNA sequencing method (sequencing by synthesis on a single substrate in parallel), have formed the basis for all subsequence next generation sequencing technologies.
Dr. Rothberg went on to invent semiconductor chip-based sequencing, and sequenced Gordon Moore as the first individual to be sequenced on a semiconductor chip (as published in Nature), and the first post-light Genome. In October 2010, Ion Torrent was acquired by Life Technologies for $725 million, the largest acquisition in the history of sequencing technology. In addition to founding 454 Life Sciences and Ion Torrent, Dr. Rothberg was the founding CEO & Chairman of CuraGen Corporation, RainDance Technologies, and Clarifi Corporation.
Dr. Rothberg was born in 1963 in New Haven, Connecticut. He earned a B.S. in chemical engineering with an option in biomedical engineering from Carnegie Mellon University and an M.S., M.Phil, and Ph.D. in biology from Yale University. He is the first person to be named a World Economic Forum’s Technology Pioneer three separate times, is an Ernst and Young Entrepreneur of the Year and received The Wall Street Journal’s First Gold Medal for Innovation. He received Nature Methods First Method of the Year Award, and The Irvington Institute’s Corporate Leadership Award in Science, and the Connecticut Medal of Technology. For his invention of massively parallel DNA sequencing and initiation of the Neanderthal Genome Project Jonathan was awarded the DGKL Biochemical Analysis Prize, and received and Honorary Doctorate of Science from Mount Sinai School of Medicine. Jonathan is a member of the National Academy of Engineering, the Connecticut Academy of Science and Engineering, and is a life trustee of Carnegie Mellon University.

“Possible Versus Practical: Engineers Must Lead the Development of Practical Technologies”
Wednesday, March 27, 2013
Abstract: Today more than ever, Engineering is about creation. Engineers design things for a particular purpose that creates a benefit. There is a strong societal desire for sources of energy and feedstocks that can support a high standard of living for all. Thermodynamic, material and economic challenges stand in the way, yet most of the general public do not have the basic understanding of the energy flows, chemical transformations, and the scale of the systems that support our current way of life. Engineers must be on the vanguard of separating hype from truly practical options. Practical limitations were ignored as the development of cellulosic ethanol rode a wave of optimism and hype earlier in this decade. It is now clear that cellulosic ethanol is not delivering on the promises made, leading the cellulosic community to move into “high value chemicals”. The pivot to chemicals fails to address the large challenges targeted by cellulosic fuels and, upon inspection, fails to create the societal value that proponents cite. Announcements occur daily of some new energy related technology touted by the scientists that discovered as something that could possibly revolutionize energy. Much of what is shown to be possible will never be practical. As engineers, we must do a better job explaining the difference between the subset of discoveries that offer practical solutions from those that are simply possible. Focusing efforts on those technologies capable of yielding practical solutions to pressing issues is our responsibility.

“Facilitated Transport Membranes for CO2 and Antibiotic Separations”
Wednesday, April 25, 2012
Abstract: This presentation covers two new facilitated transport membranes: (1) carbon dioxide-selective membranes for CO2 separation and hydrogen purification for fuel cells and (2) supported liquid membranes (SLMs) with strip dispersion for recovery of antibiotics. We have synthesized CO2-selective membranes by incorporating amino groups into polymer networks. The membranes have shown high CO2 permeability and selectivity vs. hydrogen, carbon monoxide and nitrogen up to 180°C. Hydrogen sulfide permeates through the membrane much faster than CO2, allowing H2S removal in the treated synthesis gas before water-gas-shift (WGS) reaction. Our initial experiments have shown a nearly complete removal of H2S from 50 ppm in synthesis gas to about 10 ppb in the hydrogen product. Using the membrane, we have obtained <10 ppm carbon monoxide in the hydrogen product in WGS membrane reactor experiments via CO2 removal. The data have been in good agreement with our modeling predictions. We also removed CO2 from a syngas containing 17% CO2 to <30 ppm and obtained >98% CO2 in the acid gas stream for sequestration.
On SLMs with their stability ensured using strip dispersion, Cephalexin has been extracted and concentrated with high recovery. A mass transfer analysis has shown that the resistance from the extraction reaction is dominant. Initial results from a 4-component feed mixture derived from its enzymatic synthesis have shown selective Cephalexin recovery possible. This allows Cephalexin recovery from the mixture in conjunction with complexation without enzyme deactivation, which commonly occurs when complexation is conducted in enzymatic reaction mixtures.

“Osmotic Propulsion: The Osmotic Motor”
Wednesday, March 2, 2011
Abstract: The design of nanoengines that can convert stored chemical energy into motion is a key challenge of nanotechnology, especially for engines that can operate autonomously. Recent experiments have demonstrated that it is possible to power the motion of nanoscale and microscale objects by using surface catalytic reactions – so-called catalytic nanomotors. The precise mechanism responsible for this motion is not known, although a number of ideas have been put forth. Here, a very simple mechanism is proposed: osmotic propulsion. A surface chemical reaction creates local concentration gradients of the reactive and product species which generate a net osmotic force on the motor. The concentration distributions are governed by the ratio of the surface reaction velocity and the diffusion velocity of the reactants. For slow reactions the reaction velocity determines the self-propulsion. When surface reaction dominates over diffusion the osmotic velocity cannot exceed the diffusive speed of the reactants. The implications of these features for different reactant concentrations and motor sizes are discussed. Theoretical predictions are compared with Brownian Dynamics simulations. Through osmotic propulsion the motor is able to harness the ever-present random thermal motion via a chemical reaction to achieve directed autonomous motion.

“Retrofitting Membranes: Wrapping Up Where Nature Left Off”
Wednesday, March 3, 2010
Abstract: Of the many wonders of biological systems, one must certainly include cell membranes – one of the most elegant and versatile packaging materials known to mankind. With amazing material properties, these strong, deformable, semi-permeable, self-healing thin films are merely the thickness of two phospholipid molecules. While many, if not most, other biological wonders are far too complicated to imitate, basic membrane structures can be readily created in the laboratory – quite a testament to the power of molecular self-assembly. In fact, the relative ease of creating closed membrane structures, such as vesicles made from phospholipids and synthetic “polymersomes” made from diblock copolymers, offers amazing building materials for more advanced structures and superstructures. Such is the motivation for the work in our laboratory, which designs advanced membrane structures for new applications, and also as platforms for fundamental biological investigations. In this talk I will describe our progress on creating and using novel structures made of vesicles, polymersomes, and hybrids of the two. Many of our structures are created by exploiting molecular interactions of biological molecules beyond nature’s design: for example, we use DNA as molecular glue for assembly purposes and we take advantage of phase separation of lipid mixtures to engineer anisotropic systems.

“A 21st Century View of Chemical Engineering”
Wednesday, March 25, 2009
Abstract: Chemical Engineering was born in the late 19th century from the rapidly expanding sciences of physical and synthetic chemistry and the need for new type of engineer who was prepared to apply these principles to the burgeoning petrochemical and energy industries. From this beginning chemical engineering has evolved into one of the premier engineering disciplines, with a rich history of both academic and industrial impact. Industrially, the modern methods of manufacturing of carbon-based fuels and bulk petrochemicals owe their development to chemical engineers, as do the processes for specialty chemicals, pharmaceuticals, and polymers. In the last quarter century, the impact of chemical engineering has become increasingly diversified into other applications, such of optoelectronic materials and devices, environmental remediation, biotechnology, and human health. Simultaneously our academic emphases have shifted toward the applied sciences and away from the engineering principles that formed the roots of the discipline.
A decade into the 21st century, is an opportune time to ask the question, are chemical engineers as relevant today as in our past? After a brief review of the history of chemical engineering, I will attempt to answer this question and will offer some advice for maximizing our impact going forward.

“Global Climate Change”
Wednesday, March 19, 2008
Abstract: Humans have embarked on an environmental experiment of unprecedented proportions. That emissions of greenhouse gases owing to human activity have caused an increase in the earth’s temperature is incontrovertible. Annual emissions of carbon dioxide now exceed 8 Gigatons of carbon, and the global CO2 concentration is increasing at a rate of 2 parts-per-million yearly. Most of the increase of CO2 in the air today, relative to pre-industrial times, is a result of burning fossil fuels. About one-fifth of the CO2 emitted today will remain in the atmosphere for 1000 years. For the past 30 years the planet has been warming at a rate of about 0.2 oC per decade. And the earth is out of energy balance by between 0.5 and 1 W/m2, which means that an additional warming of about 0.5 oC is “in the pipeline” even if greenhouse gas emissions were to be stabilized at today’s values. The ability to simulate observed temperature trends and therefore to project into the future is hampered by uncertainties, most notably associated with the role of particles (aerosols) in the air. This talk will discuss the scientific foundation of global climate change and address the role of aerosols in present and future climate.

“Commercializing Membrane Reactors: From Penn to Pure-Isomer Drugs”
(What John Quinn Didn’t Teach Us!)
Wednesday, March 28, 2007
Abstract: Sepracor Inc., a venture-capital-funded start-up co-founded by the author in 1984, has subsequently grown to be a profitable specialty pharmaceutical company with a market capitalization of order $6 billion, annual revenues of $1 billion, and a payroll numbering over two thousand. Although one would hardly surmise it from the company’s current portfolio of self-marketed or licensed pharmaceutical products including LunestaTM, Xopenex, Allegra, and Clarinex, Sepracor was originally organized to commercialize the author’s thesis research at Penn with John Quinn on enzyme membrane reactors for the optical resolution of racemic mixtures of chiral drugs. The company’s initial business model contemplated selling an array of bench-, pilot-, and process-scale membrane reactor modules and systems to pharmaceutical companies and their suppliers.
The capstone of this effort was the installation and operation in Japan of a commercial-scale membrane reactor plant that produced 75 metric tons per year of the key chiral intermediate used in making diltiazem (Cardizem), a calcium channel blocker indicated for hypertension and angina. Most of the diltiazem produced during the early-to-mid ’90s was made using Sepracor’s membrane reactors – an achievement realized in large measure due to the efforts of yet another John Quinn advisee, Dr. Jorge Lopez. And yet the company never repeated this success, nor does it practice the technology today! Sepracor’s original suite of membrane products has been supplanted by a porfolio of pure-isomer and active-metabolite drugs.
What accounts for this? Should Sepracor’s experience be regarded as a success or a failure from the standpoint of commercializing membrane reactors? Should its membrane reactor technology be viewed as a “one-trick pony” – or as a pioneering application of a promising platform technology? What technical and business lessons can be learned from this, and what are their implications for others aspiring to take emerging chemical technologies to market? Are they still not teaching you something at Penn?
Biography: Dr. Stephen Matson is currently engaged in starting ConTechs Associates Inc., a non-profit seeking to execute societally meaningful engineering projects in developing countries through teams comprised of engineering students and their professors in those countries working collaboratively with engineering volunteers from the U.S. ConTechs’ operations to date have focused on Bolivia and the application there of so-called “appropriate chemical technologies” – e.g., the production of biofuels and the conversion of natural gas to diesel via relatively low-capital-cost processes.
Although Dr. Matson insists that ConTechs is his first intentionally not-for-profit enterprise, during his largely industrial career he has co-founded or advised several other technology start-ups – some profitable, others not. In 1984 he co-founded Sepracor to commercialize earlier PhD research with John Quinn at Penn on enzyme membrane reactors as applied to chiral separations; Sepracor is now a profitable mid-cap company focused on developing and marketing improved single-isomer pharmaceuticals. He has participated in other start-up ventures in fields as diverse as combinatorial chemistry, biochromatography, blood filtration, and high-throughput DNA sequencing. He consults in the areas of bioseparation and biocatalysis, membranes and membrane processes – especially those involving functional membranes — and intellectual property management.
Dr. Matson received his BS and MS in Chemical Engineering from Cornell (1971 and 1974) and his PhD from Penn in 1979. A registered professional engineer, he has worked in companies with as few as two and as many as 30,000 employees. Previous employers include GE R&D (1973-82), Bend Research (Director of Research, 1982-84), and Worcester Polytechnic Institute (Francis Manning Professor of Chemical Engineering, 2001-03). Dr. Matson has fifty journal articles, book chapters, and issued U.S. patents to his credit. Service to the profession includes terms as director of the American Institute of Chemical Engineers, president and director of the North American Membrane Society, and J. Memb. Sci. editorial board member.
Dr. Matson is a recipient of AIChE’s Professional Progress Award and a Fellow of the American Institute for Medical and Biological Engineering. In 1995 he was elected to the National Academy of Engineering — one of several John Quinn advisees to enjoy this distinction.

“What Are Cells ‘Thinking?’ (And How Might We Think About This…?) An Engineering Approach to Understanding How Signaling Networks Govern Cell Behavior”
Wednesday, March 1, 2006
Abstract: Cell behavioral functions are governed by biomolecular networks that translate stimulatory cues (e.g., ligand/receptor binding interactions, mechanical stresses, pathogen infection, and other environmental insults) into intracellular signals which regulate transcriptional and post-transcriptional, metabolic, and cytoskeletal processes that effect proximal and ultimate cell responses. While there is a growing body of work enhancing our understanding of how intracellular signals are generated by stimulatory cues, an exceptionally difficult challenge at the present time is to understand how these signals operate in integrated manner to govern cell behavioral responses. We are undertaking efforts to address this question by means of a combination of quantitative, dynamic protein-centric experimental manipulations and measurements with a spectrum of computational mining and modeling approaches. Particular application problems of our interest include cell migration, proliferation, differentiation, and death, with an emphasis on ascertaining how effectiveness of prospective therapeutics might be predicted. This talk will present an overview of our perspective and approach, along with a specific example vignette.

“Adventures in Micro-Fabrication: Patterning of Thin Polymer Films via Electrostatic and Elastic Instabilities”
Monday, January 24, 2005
Abstract: Interest in replicating, cheaply and easily, patterns carved into a silicon wafer by electron beam lithography motivated a simple mechanical process, known as nanoimprint (Chou, Princeton) or soft lithography (Whitesides, Harvard). This consists of pressing a mask carrying the pattern of interest (and coated with a mold release agent) against a second unpatterned wafer bearing a thin spin-coated layer of polymer and heating this sandwich above the glass transition temperature of the polymer. Cooling back to ambient conditions, after allowing the polymer to flow into conformation with the pattern, and separating the wafers yields a faithful replica of features smaller than ten nanometers. Practical implementation of this technique is now well advanced. Along the way, though, a number of other intriguing phenomena have been discovered, demonstrating that well-established laws of physics can still yield surprising outcomes at less familiar (colloidal) length scales. Two of these will be described in this talk.
The first is initiated when the mask described above fails to contact the polymer film, leaving an air gap of a few hundred nanometers. Electric fields, either natural or imposed, exert a force on the polymer-air interface, placing the film in either tension or compression. This static equilibrium is unstable to disturbances with wavelengths for which the electrostatic force overcomes the surface tension. Flow ensues, generating a periodic pattern that varies according to the nature of the mask, the ratio of the film thickness to the gap, and a number of other parameters. With unpatterned wafers triangular arrays of pillars (or holes), rosettes, or concentric rings can emerge.
The second was discovered while attempting to reduce the spacing between pillars on unpatterned wafers down to the nanoscale. Our strategy was to decease the interfacial tension by filling the air gap with a second polymer layer. Separating the two wafers, neither of which was coated with the mold release agent, after heating and cooling revealed large areas covered with parallel lines, rather than the hexagonal arrays of pillars expected. Simplifying the geometry to a single polymer layer between two flat wafers produced the same result. Varying the separation produced spacings between the lines consistently equal to four times the layer thickness. Here an instability driven by elastic stresses generated while prying the wafers apart produces fractures that propagate with beautiful regularity into the film.

“The Diversity of Electrokinetics: Nonuniformly Charged Surfaces”
Thursday, March 29, 2004
Abstract: Electrokinetics (sometimes referred to as electrohydrodynamics) is a set of phenomena where an electric field and fluid momentum are coupled. For example, an electric field moves a charged particle through a liquid (electrophoresis), or it moves the liquid past a stationary charged interface (electroosmosis). Until recently, research into electrokinetic phenomena was focused on uniformly charged systems, e.g., a spherical particle with a uniform charge density on its surface, but over the past fifteen years more attention has been paid to complex geometries and charge distributions. Here I will talk about particle and fluid motions that result when an electric field interacts with surfaces that have nonuniform charge. Examples include electrophoretic rotation and alignment of particles, circulatory liquid flows in nonuniformly charged capillaries and cavities, and electroosmotic-driven self assembly of particles on electrodes. Such phenomena are relevant to alignment of particles in suspension, microfluidics, and patterning surfaces with colloidal particles.
