Soft Nanomaterials Laboratory

Advanced Chemical Technologies Laboratory, The Unit Operations and Biotechnology Laboratory (Undergraduate Teaching Laboratory)

Director: John C. Crocker
Location: 1st Floor, Towne Building

The Unit Operations and Biotechnology Laboratory is housed within the Advanced Chemical Technologies Lab which was designed to create new knowledge and applications in emerging technologies. It provides a flexible facility where students gain hands-on experience with state-of-the-art instrumentation and experimental techniques in an environment that encourages interaction and collaboration between the faculty and graduate student research enterprise and our undergraduate students.

In the Unit Operations section of the laboratory, undergraduate students conduct experiments about kinetics, reaction engineering, humidification operations, fluid flow, separations processes, and heat transfer. Here, students learn how to conduct experiments using automated processes and digital data acquisition.

In the Biotechnology section of this laboratory, undergraduates conduct bench-scale experiments involving the growth and genetic manipulation of cells; measurements on proteins and DNA; manipulation of biomolecules such as cutting, joining and amplifying DNA, linking biomolecules to solid surfaces, and separating and purifying them.

The Gorte Lab

Director: Raymond J. Gorte
Location: 5th Floor, Vagelos Labs

The laboratories of Professor Gorte are well equipped for general synthesis and characterization of materials. Two catalytic reactors capable of on-line GC analysis of products are available, as well as capabilities for temperature programmed oxidation and reduction measurements, with product analysis using a quadrupole residual-gas analyzer. A Mattson FTIR with DRIFTS attachment is available for taking IR spectra of materials in controlled environments. Several autoclaves are present for synthesis of materials, as well as furnaces with a variety of temperature ranges and capabilities for controlled environments. Two vacuum-capable microbalances, two microcalorimeters, and an atomic absorption spectrometer are available for additional characterization.

Ceramics processing instrumentation is available for tape-casting to synthesize model fuel cells and for performance testing of the model cells. Capabilities for impedance spectroscopy measurements are also available.

Environmental Research Laboratory

Director: Wen K. Shieh
Location: Third Floor, Towne Building

The Environmental Research Laboratory is designed to carry out research work related to biodegradation of anthropogenic organic compounds, biological nitrogen removal (BNR) using either suspended or attached-growth bioreactor configurations, and sustainable aquaculture practices. The laboratory houses a number of reactor systems (e.g., biofluidized bed reactors and submerged packed-bed reactors) that are custom-made for specific biodegradation and BNR applications. Three 100-gallon acrylic fish tanks equipped with on-line pH, dissolved oxygen, and temperature monitors are available for aquaculture studies. In addition, the laboratory is well-equipped with the analytical instruments commonly found in modern environmental laboratories for physical, chemical, and biological analyses. Notably, the laboratory has a total organic carbon (TOC) analyzer, a high-performance liquid chromatography (HPLC) system, two gas chromatography (GC) systems, a nitrogen digestion and distillation system, two UV-VIS spectrophotometers, two electrolysis cell respirometers, two autotitration systems, a cell culture incubator, and a video microscopy system. Common auxiliary equipment includes peristaltic pumps, pH meters, specific ion meters, ORP meters, and dissolved oxygen meters.

The Vohs Lab

Director: John M. Vohs
Location: 5th Floor, Vagelos Labs

The surface characterization laboratories of Professor Vohs are well equipped to carry out fundamental studies of the relationships between the structure and reactivity of both model and high surface area catalysts.  Currently, there are four separate ultra-vacuum-system surface analysis systems in the lab.  Each of these systems is equipped with an ion gun for sputter cleaning of surfaces, evaporative metal deposition sources, a film thickness monitor, and mass spectrometer for performing TPD studies.  One system is set-up to perform X-ray photoelectron spectroscopy and is equipped with a Leybold-Hereaus EA-10 electron energy analyzer and a Vacuum Generators dual anode X-ray source.  Two of the systems are equipped with high-resolution electron energy loss spectrometers.  One of these contains a McAllister HREEL spectrometer and a cylindrical mirror analyzer for Auger electron spectroscopy.  The other contains an LK Technologies model 3000 HREEL spectrometer which has an instrumental resolution of 1 meV as measured by the full width at half max of the elastic peak.  This system is also equipped with a retarding field electron energy analyzer that can be used for both LEED and AES.  All of the mass spectrometers and spectroscopic probes on these UHV systems are interfaced to PCs for automated data collection. In addition to the UHV facilities Professor Vohs also has a diffusion-pumped high vacuum TPD-TGA system.  This system is quipped with a Cahn microbalance, oven for sample heating, mass spectrometer for gas analysis, and a gas handling system.  This system is also computer controlled.  Professor Vohs' labs are also equipped with a Mattson FTIR spectrometer with a Spectratech DRIFTS cell and a home built microcalorimeter.
