Nanostructured materials intrinsically possess large surface area (interface area) to volume ratios. It is this large interface area that gives rise to many of the amazing properties and technologies associated with nanotechnology. In this class, we will examine how the properties of surfaces, interfaces, and nanoscale features differ from their macroscopic behavior. We will compare and contrast fluid-fluid interfaces with solid-fluid and solid-solid interfaces, discussing fundamental interfacial physics and chemistry, as well as touching on state-of-the-art technologies.
This course is a group design project (i.e., not a lecture course). In the class, student groups research the various forms of alternative energy and then model a real-world alternativeenergy process. The goal of the project will be to develop a process model that is sufficiently complete and robust that it can be used to understand the important factor in the process design and/or operation. This design project is focused on the role of alternative energy in the US and world economies. The remainder of the course will be devoted to a technical and economic analysis of an alternative energy technology. This course is organized to replicate group project work as it is practiced in industry. The class is divided into groups (typically 3 or 4 students) and each group meets separately each week with the instructor. Hence, there are no regularly scheduled class times; student groups sign up for weekly meeting times using Starfish in Blackboard. These meetings typically will be 60 minutes long. The expectations and assignments for this course are quite different from most other courses. There are no weekly lectures by the instructor. Rather, each week each group will make a PowerPoint presentation on the week’s topic or their progress on their project. Prerequisite(s): 540.202 Introduction to Chemical & Biological Process Analysis; 540.203 Engineering Thermodynamics; 540.301 Kinetic Processes; and 540.305 Modeling and Statistical Analysis of Data for Chemical and Biomolecular Engineers. Course Note(s): Graduate Level. Meets with 540.401 Projects in Design: Alternative Energy.
This is a design course in which the design projects will be to develop pharmacokinetic models of the human body that can be used to understand the temporal distribution, spatial distribution, and bioavailability of pharmaceutical drugs. The course (and software to be developed) will cover the spectrum of factors affecting pharmaceutical bioavailability including drug formulation, mode of dosing and dosing rate, metabolism and metabolic cascades, storage in fatty tissues, and diffusional limitations (such as in crossing the blood-brain barrier or diffusional differences between normal and cancerous cells). The goal is to develop process models of the human body that will predict pharmaceutical bioavailability as a function of time and organ (or cell) type and that will work for a wide variety of pharmaceuticals including small molecules, biologics, and chemotherapy agents. This course is organized to replicate group project work as it is practiced in industry. The class is divided into groups (typically 3 or 4 students) and each group will meet separately each week with the instructor. Hence, there are no regularly scheduled class times; student groups sign up for weekly meeting times using Starfish in Blackboard. These meetings typically will be 90 minutes long. The expectations and assignments for this course are quite different from most other courses. There are no weekly lectures by the instructor. Rather, each week each group will make a PowerPoint presentation on the week’s topic or their progress on their project.
Polymeric materials are ubiquitous in our society, from naturemade proteins and polysaccharides to synthetic plastics and fibers. Their applications range from day-to-day consumables to high-performance materials used in critically demanding areas, such as aviation, aerospace, and medical devices. The objective of this course is to provide an introductory overview on the field of polymer science and engineering. Students will learn some basic concepts in polymer synthesis, characterization, and processing. With the basic concepts established, industrial applications of polymeric materials will be discussed in two categories: structural polymers and functional polymers. Structural polymers, including plastics, fibers, rubbers, coatings, adhesives, and composites, will be discussed in terms of their structure, processing, and property relationship with a flavor of industrial relevant products and applications. Future trends in developing environmentally friendly polymers from renewable resources (green polymer chemistry) will also be covered. Lectures on functional polymers will focus on their unique properties that are enabled by rational molecular design, controlled synthesis, and processing (e.g., supramolecular assembly and microfabrication). This class of specialty materials can find their use in high-performance photovoltaics, batteries, membranes, and composites and can also serve as smart materials for use in coatings, sensors, medical devices, and biomimicry.
Nanomedicine is a quickly growing area that exploits the novel chemical, physical, and biological properties of nanostructures and nanostructured materials for medical treatments. This course presents basic design principles of constructing nanomaterials for use in drug delivery, disease diagnosis and imaging, and tissue engineering. Three major topics will be discussed, including (1) nanocarriers for drug delivery that are formed through soft matter assembly (e.g., surfactants, lipids, block copolymers, DNA, polyelectrolytes, peptides); 2) inorganic nanostructures for disease diagnosis and imaging (e.g., nanoparticles of gold and silver, quantum dots and carbon nanotubes); and (3) supramolecular scaffolds for tissue engineering and regenerative medicine. Students are expected to learn the physical, chemical and biological properties of each nanomaterial, the underlying physics and chemistry of fabricating such material, as well as their advantages and potential issues when used for biomedical applications. This course will also provide students opportunities for case studies on commercialized nanomedicine products. After this class, students should have a deeper understanding of current challenges in translating nanoscience and nanotechnology into medical therapies.
In this course we will aim for understanding the thermodynamics of chemical and biomolecular systems. We will first review classical, macroscopic thermodynamics, covering concepts such as equilibrium, stability, and the role of thermodynamic potentials. Our goal will be to gain a feel for the generality of thermodynamics. Statistical mechanics provides a link between the mechanics of atoms and macroscopic thermodynamics. We will introduce this branch in two distinct ways: (1) following standard methods of developing concepts such as ensembles and partition functions, and (2) where we will treat the basis of statistical mechanics as a problem in inference. With this foundation, we will consider concepts relevant to understanding the liquid state. Chemical transformations in a liquid are of importance in much of chemistry and biology; quasi-chemical generalizations of the potential distribution theorem will be introduced to present these ideas. We hope to give an overview of modern developments relating equilibrium work to non-equilibrium work, as these are of increasing importance in studies on single molecule systems. Registration by instructor permission only.
One of the most promising strategies for successfully designing complex biomolecular functions is to exploit nature’s principles of evolution. This course provides an overview of the basics of molecular evolution as well as its experimental implementation. Current research problems in evolution-based biomolecular engineering will be used to illustrate principles in the design of biomolecules (i.e., protein engineering, RNA/DNA engineering), genetic circuits, and complex biological systems including cells.
This course involves a semester-long project in pharmacodynamics. Topics are chosen in consultation with instructor.

No prerequisites for graduate students.
Fundamental concepts in drug delivery from an engineering perspective. Biological organisms are viewed as highly interconnected networks where the surfaces/interfaces can be activated or altered “chemically” and “physically/mechanically.” The importance of intermolecular and interfacial interactions on drug delivery carriers is the focal point of this course. Topics include drug delivery mechanisms (passive, targeted); therapeutic modalities and mechanisms of action; engineering principles of controlled release and quantitative understanding of drug transport (diffusion, convection); effects of electrostatics, macromolecular conformation, and molecular dynamics on interfacial interactions; thermodynamic principles of selfassembly; chemical and physical characteristics of delivery molecules and assemblies (polymer based, lipid based); significance of biodistributions and pharmacokinetic models; toxicity issues; and immune responses.
An introduction to the phenomenology of nonlinear dynamic behavior with emphasis on models of actual physical, chemical, and biological systems, involving an interdisciplinary approach to ideas from mathematics, computing, and modeling. The common features of the development of chaotic behavior in both mathematical models and experimental studies are stressed, and the use of modern data-mining tools to analyze dynamic data will be explored. Emphasis will be placed on the geometric/visual computer-aided description and understanding of dynamics and chaos. Prerequisite(s): Knowledge of linear algebra and ordinary differential equations (at an undergraduate level); some computing experience is desirable.
In this graduate-level course, we will cover important principles in thermodynamics and kinetics along with examples relevant to engineering practice. After a short review of the first and second laws of thermodynamics, we will move on to their application in engines and refrigeration. We will discuss the thermodynamic properties of systems consisting of pure species and mixtures and address phase equilibria. With the key thermodynamic concepts in place, we will discuss topics in kinetics, including the fundamentals of reaction rates, rate laws, multiple reactions, and nonelementary reaction kinetics. Finally, we will address how reactor type and properties, transport limitations, and phase equilibria influence reaction rate.
This course inherently combines green engineering, alternative energy and CO2 capture and storage into a concentrated semester lecture. Green Engineering applies the cost-effective design, commercialization, and use of chemical processes in ways that minimize pollution at the source, and reduce impact on human activities and the environment. After general discussion of applying environmental principles into various chemical processes, this course will switch the gear to apply these green engineering ideas into the energy production that has increasing and critical importance to our modern world, how to minimize the pollution and CO2 emission. There are two ways to follow: 1. Alternative Energy, which uses alternative resources rather than the current dominant fossil fuel for energy production. Alternative energy includes solar, hydro, bioenergy, geothermal, tidal, nuclear energy and et al. The detailed production processes, the long term perspective, policy and advantages/disadvantages over their counterpart, fossil fuel, will be discussed. 2. Fossil fuel with CO2 Capture and Storage. CO2 capture methods such as chemical solvents/chemical looping, membrane, oxy fuel combustion will be discussed and their technical benefits/limitations will be studied. The storage will cover geological methods (coal bed and saline aquifer), enhanced oil recovery, ocean storage, terrestrial and others. The technical details, cost, future trends and national/international policy (carbon taxes/markets) will be discussed in this course.
Chemical reaction engineering deals with the analysis on data and the design of equipment in which reactions occur. Reactors may contain one or more phases and be used to conduct chemical or biochemical transformations. The course will cover the fundamental aspects of kinetics, data acquisition, data interpretation, heterogeneous catalysis, and heat and mass transfer for each type of reactor. Special emphasis will be placed on the practical application of reaction engineering in the petrochemical, chemical, biochemical, and materials industries. The course will make students aware of the needs and opportunities for chemical reaction engineering in industry.
This course is one part of a two-semester sequence in chemical and biomolecular engineering product design. It is intended for students in the Chemical and Biomolecular Engineering master’s program. This course guides the student through the complex process of new product design. Product designconcerns the recognition of customer needs, the creation of suitable specifications, and the selection of best products to fulfill needs. Students work in small teams to develop a new product idea, design the product, and then iterate on prototype development. Students report several times on their accomplishments, both orally and in writing. Time is allowed so that laboratory tests can be performed and/or prototypes can be built.
