Professor Sema Kalaian A Designed Experiment to Determine the Effects of Melt Temperature, Hold Pressure, Hold Time, and Nylon Moisture Content on Surface Profile
Various types of polymers are utilized in the automotive industry. To exploit the unique properties of these polymers, one must have the ability to effectively manufacture product using conventional injection molding equipment. The objective of this project was to determine if melt temperature, hold pressure, hold time, and nylon moisture content have a significant effect on surface profile during injection molding of TPO fascia. A 150-ton injection molding machine was utilized to conduct the experiment. In order to determine the effects of melt temperature, hold pressure, hold time, and nylon moisture content on surface profile, a thirty-two run, 24 full factorial designed experiment was utilized. In this experiment, the researchers chose factors that affect surface profile for a molded TPO fascia. Extensive opportunity exists for subsequent researchers to explore significant affects of injection molding parameters on various applications utilizing TPO.

Professor John Texter New Polyurethane Resins for Epoxy Replacement
Microemulsion and solvotrope polymerizations are being developed for synthesizing polyurethane prepolymers from the step monomers. These prepolymers are converted to resins using new secondary-amine cross-linking agents to produce polyurethane resins suitable for replacement of epoxies in primers used for jet aircraft. Kinetic, thermodynamic, and thermomechanical characterization methods are used to provide insight into the step polymerization processes and the cross-linking processes and to compare physical and performance properties with the epoxy systems to be replaced. These analyses include microcalorimetry of prepolymer formation kinetics, dynamical mechanical analysis of resins, and diffusing wave spectroscopy of film formation relaxation processes.

Professor Shinming Shyu The Quest for Quiet: Noise Management in Interior Spaces
Among the various environmental concerns, the effects of noise pollution are considered less harmful than other forms of pollution. The researcher investigated why there is not very much information on this. Readings showed that a lack of government funding contributes to noise pollution not being treated as an important concern. There are several health effects that can be directly attributed to high levels of noise, including stress, anxiety, and hearing loss. This presentation also discusses possible ways to control noise levels in interior spaces.

Professor John Texter Dielectric and Thermomechanical Analysis of Tg and Tm Transitions of PDMS-Based Marine Coatings
Commercial and developmental marine (fouling release) coatings based on polydimethylsiloxane (PDMS) have been studied by dynamical mechanical analysis (DMA) and by dielectric spectroscopy (DS). The Tg and Tm processes for PDMS in all of the samples were discernable in the permittivity and storage modulus spectra. They were also discernable in the DMA loss spectra, but in the dielectric loss spectra they could not be resolved among the additional loss mechanism that come into play. A loss mechanism at about 100 Hz was found by DS to be associated with the Tg. Over the 100-125°C range, a loss mechanism at about 3-4 Hz appears. Samples were examined as a function of thickness. Dielectric spectra showed increasing permittivity and loss values with increasing sample thickness, but DMA spectra generally showed an opposite trend.

Professor John Texter Reversibly Porating Materials and Coatings
A new class of hydrogel/solvogel copolymers has been derived by microemulsion polymerization of methacrylates and reactive ionic liquid surfactants in aqueous-methacrylate-surfactant microemulsions. Depending on the cross-linking density, the resulting gels (transparent or translucent) can be reversibly transformed into microporous or nanoporous materials with open cell structures via spinodal decomposition of the gel phases. Reversibility is aided by the cross-linking. The spinodal decomposition is induced by changing the solvent quality from good to poor for the copolymeric blocks containing the polymerized ionic liquid surfactant. They provide solvent-reversible opacity as an overcoat to otherwise transparent materials. With suitable cross-linking, such materials may also provide porous fabric coatings for repelling water while allowing vapor to freely permeate. Porosity varies with composition throughout the precursor, single-phase microemulsion domain. Conductivity studies provide transition markers for the onset of percolation through strings of reverse microemulsion droplets and for transformation to the irregular bicontinuous microemulsion mesostructure.

Professor Vijay Mannari Smart Polyurethanes with Selective Surface Properties for Marine Coatings Applications
Various eco-friendly approaches have been studied in the recent years for effectively controlling biofouling on to the marine structures. Amongst these, two commonly known approaches are (a) use of hydrophilic surfaces that control biofouling by resisting adhesion of organism on to the surface and (b) use of hydrophobic surfaces that function by facilitating their easy removal. The present study attempts to investigate amphiphilic surfaces for their effectiveness in controlling marine biofouling. Polyurethane surfaces containing tethered hydrophilic, hydrophobic, and amphiphilic moieties have been synthesized. The wetting behaviors of these surfaces, as a function of external environment, have been studied by Dynamic Contact Angle (DCA) measurements and their morphologies by Atomic Force Microscopy (AFM). The results from DCA, AFM, and bioassays with the green fouling alga Ulva showed that the amphiphilic surfaces have antifouling and fouling release potential and provide an insight into the scope for development of smart marine coatings.

Professor Vijay Mannari Effect of Addition of Inorganic Corrosion Inhibitors in Sol-gel Coatings on Performance of Aerospace Aluminum Alloy
Effective pretreatment of aluminum alloys is critical to the success of protective coating systems for aerospace applications. Chrome-based pretreatments, while very effective in corrosion-resistance performance, have been targets for replacement due to their toxicity issues. There has been significant pressure to develop chrome-free systems to comply with the increasingly stringent regulations. Among many approaches to develop such systems, the organic-inorganic hybrid coatings based on Sol-gel technology has advanced rapidly. We have successfully developed a Sol-gel coating system based on Bis-ureasil type silane compounds. In the present study, inorganic inhibitors will be used to study their corrosion performance in Sol-gel matrix. Our study shows that by proper choice of sol-gel precursors, cross-linkers, and reaction conditions, very dense adherent and protective hybrid coatings on aerospace aluminum alloys can be obtained. Results of corrosion resistance studies—Potentiodynamic scans, Salt-spray resistance test-of various compositions and their comparison will be discussed.

Professor Shinming Shyu A Look at Airports, Present and Future
Air travel used to be an exciting experience, and it has certainly inspired the architecture and design of our century to a perhaps greater degree than anything else, including the automobile. Yet, because we as a nation have grown accustomed to the experience of flying, the airport and airplane now take on almost invariably negative connotations as being noisy, unsafe, overcrowded, and difficult to navigate. So the question is: What can designers do to facilitate a safer and more comfortable travel experience? An examination of air travel and airport stresses could explain what has happened over the past decade and how to address it.

Professor Xiaoxu Han ELK: A Statistical Tool to Classify Microarray Data
Q5 is a composite classification algorithm that was applied to complete Mass Spectrometry (MS) data from human blood samples using Surface-Enhanced Laser Desorption/Ionization Time of Flight (SELDI-TOF) in an effort to properly classify samples from cancer datasets. Q5 was able to successfully classify MS cancer data. Q5 has the inherent limitation of having difficulties in classifying multimodal data where any given class has separate clusters, due to the use of global information only. The work described here was focused on classifying microarray datasets. The underlying method was to substitute the algorithms used by Q5 with algorithms that preserve local clustering information through each step of the process. Four new composite algorithms were developed. The new algorithms and Q5 were tested against cancer datasets using multiple sets of experimental parameterizations. Two of the new algorithms were able to classify two and three class leukemia data more accurately than Q5.
