The chemical conversion of resources into new, more useful forms has been the traditional concern of chemical engineering. In recent years, chemical engineering has played a major role in high technology advances in biotechnology, sustainable energy, and novel materials processing. In addition, a critical concern with the depletion of resources has developed, leading to increased efforts to conserve, recycle, and find environmentally friendly alternatives.

The major educational objective in the Howard P. Isermann Department of Chemical and Biological Engineering is to prepare students to enter their engineering practice dealing with chemical as well as physical processes to meet the challenges of the future. The curriculum, which builds on chemistry, biology, mathematics, basic sciences, and engineering science, culminates in professional applications in which theory is tempered by engineering art and economic principles. Through this curriculum, graduates are prepared equally well for professional practice or for advanced study.

Opportunities for creative and satisfying practice in chemical and biological engineering can be found in conception, design, control, or management of processes involving chemical and/or biochemical transformations. These processes range from the more conventional conversion of crude oil into petrochemicals and plastics, to the microbiological transformation of hardwood chips into specialty alcohols, or to the creation of semiconductor devices from silicon wafers. Diverse career choices exist not only in the chemical industry, but in virtually all processing industries, including agricultural, biotechnology, chemical, food, nuclear, semiconductor processing, and environmental operations. By emphasizing basic principles, the program prepares its graduates for positions spanning the spectrum of activities from research and development, to process and project engineering, to production, or to technical marketing.

Research Innovations and Initiatives

Biochemical Engineering
Research projects in biochemical engineering emphasize biocatalysis, bioseparations, and metabolic engineering. Fundamental and applied aspects of enzyme technology, mammalian cell culture, membrane sorption and separation, displacement chromatography, and salt-induced precipitation are important areas of focus. New designs involving aqueous and nonaqueous enzyme technology are being developed, as are new types of membrane-entrapped-enzyme and animal-cell-suspension reactors, which are being built, tested, and analyzed. Metabolic engineering processes are being used to develop high-rate bacterial fermentations and overproducing hybridoma cultures for producing chemical intermediates and monoclonal antibodies, respectively. Control theory of biological processes and an optical biosensor for metal detection are also being pursued. Projects closely related to biomedical engineering involve the design of polymeric inhibitors of bacterial toxins and viruses, and the use of microfabrication tools to modulate the interaction of mammalian cells with their environment for applications in tissue engineering.

Separation and Bioseparation Processes
Research projects in separation and bioseparations employ fundamental concepts for solving applied problems in the biological and environmental fields. Current projects emphasize interactions of proteins with synthetic membranes and chromatographic media, high throughput screening, combinatorial and computational chemistry, spectroscopy, chip technology, proteomics, modification of polymeric surfaces for bioseparations and environmental applications, and the recovery of proteins from complex biological solutions using fusion affinity adsorption, pressure-driven membrane processes, displacement chromatography, and expanded-bed adsorption. Other projects focus on the design and synthesis of high-performance artificial membranes inspired by biological membranes, for environmental processes and chemical production.

Molecular Modeling and Simulations
Monte Carlo and molecular dynamics simulations are being used in combination with statistical mechanical theories to understand thermodynamics, structure, and kinetics of biomolecules in aqueous solutions. Special emphasis is placed on understanding and relating water structure near different solutes and in different environments to resulting interactions (e.g., hydrophilic and hydrophobic interactions). Theory and molecular simulations are also used to study the effects of geometrical and chemical heterogeneity on molecular transport and reaction in porous catalysts, sorbents and membranes, and to apply this knowledge to their rational design.

Advanced Materials
Research area includes two dimensional materials such as graphene, MoS2, etc.  It also involves other low dimensional materials where quantum effects are important. Material synthesis will be explored, while the research will also include nanofabrication of optoelectronic devices based on these materials. Also novel  optical and electrical measurement setups to better characterize these materials. These setups include confocal scanning microscope, photocurrent microscope, photoluminescence and Raman microscopy as well as ultrafast optical spectroscopy.

Interfacial Phenomena
Problems under investigation include interfacial resistance to mass transfer and the interaction between surface forces and interfacial convection. Work in the interfacial area is concerned with heat, mass, and momentum transfer in multicomponent, ultrathin, liquid films. Research includes studies on condensation and evaporation in the contact line region, distillation from ultrathin films, lubrication, surface-tension-driven instabilities in atomically clean liquid metals, pattern formation in dendritic growth, protein-solid interaction, and the design of biocompatible surfaces.

Polymers
The polymer research program focuses on understanding fundamental properties of nanostructured polymers and their applications on various energy problems. Current research focuses are thermodynamics of polymer mixtures, rational design of nanostructured polymers for ion-transporting membranes, and long-range ordered structures by self-aggregated block copolymers in melts and solutions. Along with advanced polymer synthesis capabilities, rheology, small angle X-ray/light scattering, and electron microscopy techniques are used as primary characterization tools in the polymer research program. 

Process Control and Design
A major focus of this research is the development of realistic, robust control strategies for multivariable chemical processes having parameter and process uncertainties. Such strategies are created to exploit the dynamic properties inherent in the systems. Integration of the modeling, design, and control of specialty chemical and pharmaceutical processes is of particular interest.

Heat Transfer
Topics of interest include free convection stability, forced convection (particularly in laminar flow systems), fluid-to-particle heat transfer in fluidized and spouted beds, and boiling. Studies on heat and mass transfer at interfaces are also under way.

Thermodynamics
Activities include molecular simulation, the analysis and correlation of phase-equilibrium data, the development and evaluation of fluid-phase equations of state, and the study of topics in solution thermodynamics.

Mass Transport
Research is in progress on simultaneous heat and mass transfer in porous media; effects of surface roughness and chemical heterogeneity on diffusion; the effects of interfacial phenomena on mass transfer; diffusion and mixing in laminar flow systems; transient dispersion processes in capillaries, porous media and open channels; and crystal growth phenomena.

Fluid Mechanics
Projects in this area involve low Reynolds number hydrodynamics, non-Newtonian fluids, two-phase flow, and interfacial flows.

Interdepartmental Research
Several research areas involve participation and cooperation with other departments. Such areas include polymer studies with the Materials Science and Engineering and Chemistry Departments, fermentation and other biochemical research with the Biology Department, studies in fluid mechanics with the Mathematics Department, polymer membrane fabrication with the Chemistry Department, and research on lubrication and other interfacial phenomena with the Mechanical Engineering Department. Additional information on research in these areas is found in the catalog sections for those departments.

Research Related Facilities
The department maintains extensive research and instructional laboratories which house myriad special and unique equipment developed for specific studies, as well as extensive analytical and optical instrumentation and computers. Major instrumentation such as a GC/mass spectrometer, an X-ray fluorescence analyzer, an ion chromatograph, HPLC systems, and a laser zee particle characterization system make Rensselaer’s laboratories one of the most comprehensively equipped university centers for research in the areas described above. Many faculty in the Chemical and Biological Engineering Department have their research labs located in the Center for Biotechnology and Interdisciplinary Studies, which is equipped with an impressive array of core imaging, analytical, and spectroscopy tools. The department research programs also use a number of major university facilities including the electron optics laboratory and the polymer laboratories in the Materials Research Center.
