Show moreA method for simultaneous detection of mycotoxins using high performance liquid chromatography (HPLC) coupled with a fluorescence detector (FLD) and photochemical reaction for enhanced detection (PHRED) for post-column derivatization was developed in this study. Mycotoxins of interest included aflatoxin B1, B2, G1, G2 and ochratoxin A. Samples extraction was performed with 80% acetonitrile aqueous solution. Mycosep® 226 Aflazon+ columns were employed for samples cleanup. This optimized method achieved low limit of detection (LOD) that ranged from 0.1ng/g to 0.5ng/g and a limit of quantification (LOQ) ranged from 0.5ng/g to 2.5ng/g for all five mycotoxins in all cereal matrices (wheat, barley, oats) studied, which was under the regulatory limit (20ng/g) from United States. Mean recovery rates for all five mycotoxins from all spiked samples ranged from 93.88% to 104.40%, with high repeatability (relative standard deviation ranged from 1.38% to 8.79%). This method was used to determined ochratoxin A in cereal samples purchased from grocery stores in the United States.

Show moreIn a pathway toward sustainable energy, natural gas is an excellent transitional fuel to displace coal, resulting in lower net carbon emissions. Thus natural gas is becoming one of the major resources of energy in near future. One of the key challenges to transport natural gas and use it in transportation industry, is how to store methane in a safe and cheap way. Adsorbed natural gas on porous material has been studied as a better storage method than compressed natural gas, because it requires the lower pressure (500 psig versus 3000 psig) and lower capital and maintenance costs. However, increasing methane storage capacity is still remaining as a major challenge. In the present work, different activated carbons were used and experimental methane adsorption and desorption runs have been conducted. Methane isotherm was obtained at 293.15 K at different pressures. Furthermore, the overall adsorption and desorption rate were calculated during adsorption and desorption procedures. The effect of the surface area and particle size distribution were also studied. After eight successive adsorption and desorption tests using activated carbons at different pressures, no change in the material capacity was observed. Our experimental results show that the adsorption capacity of activated carbon particles will be increased using smaller particles with wide particle size distribution. This is mainly due to accumulation of smaller particles in space between large particles which in turn increase total material available for adsorption in a specific volume.

Show moreThe oscillatory structural force (OSF) of a micellar film of sodium dodecyl sulfate (SDS) was monitored with atomic force microscope (AFM) using an attached glass microsphere against a smooth flat and energy homogenous solid substrate. The force versus distance measurements for the 0.03M and 0.06 M SDS micellar solutions were monitored. The force versus distance had an oscillatory decay profile with a period of oscillation which was the same as the micellar diameter. The number of periodic oscillations increased with an increase in the micellar concentration. The OSF in the SDS micellar film confinement was also proved by a thinning single foam film formed from a micellar solution. It was observed that, due to micellar layering, the film thinned in a multiple regular stepwise manner promoted by the OSF. The results obtained by the AFM and thinning single foam film were used in the application of the OSF to remove bacteria from a model solid substrate. The experimental data for the OSF was complemented with modeling research. The theoretical OSF curves were obtained using the statistical mechanics approach. The experimental data and theoretical results for OSF for SDS micellar film were analyzed and found to be in fair agreement with each other. Based on the model prediction calculation, the structural film interaction energy barrier for the both the 0.03 M and 0.06 M SDS micellar solutions was calculated; the estimated structural film interaction energy barrier due to the presence of the OSF was about 10 3 kT / 􀝉􀬶 for the 0.03 M SDS micellar solution and about 5 x 10􀬷 kT /􀝉􀬶for the 0.06 M SDS micellar solution in film with micellar layers at about 25 ºC. Understanding the interactions between bacteria and solid surfaces that result in bacterial adsorption and removal is of immense importance for reducing foodborne illness outbreaks. Here, we used fluorescence microscope in conjunction with the concept of the diffusion of bacteria from the bulk suspension to the substrate and the adsorption isotherm to estimate the adsorption energy for E.coli K12; we obtained a value of about 2.5 kT. This value compares favorably with the value of 2.1 kT reported previously for E.coli NCTC 9002 [49]. We also used the dynamic light scattering method to estimate the radius of gyration of E.coli K12, which has a diameter of about 1 m and a length of 2 m to estimate the effective volume. The radius of gyration was also used to estimate the surface area covered by the bacterium and compared it to the surface area measured from the image taken with fluorescence microscope. A nanofluid formulation comprised of a sodium dodecyl sulfate (SDS) micellar aqueous solution in the presence of an organic acid (as a pH controller) was used to test the E. coli K12 removal from two substrates, polyvinylchloride (PVC) and partially hydrophobic glass. We investigated the bacterial removal efficacy based on the combined effect of the nanofluid’s structural forces and bacterial isoelectric point. We predicted the nanofilm oscillatory structural energy (NOSF) against the E.coli K12 adsorption energy by applying the statistical mechanics approach. Based on the model prediction, the NOSF was estimated at the vertex of three phase contact angle between a bacterium and the substrate (i.e., the wedge film’s interaction energy at one particle layer). The evaluated film’s repulsive energy due to the NOSF was about 15.6  4.4 kT of the 0.02 M SMNF (the SDS micellar nanofluid formulation) and several times higher than the bacterial adsorption energy, 2.5  0.2 kT. These findings suggest that the NOSF is capable of bacteria/microorganism removal from contaminated substrates. Here, we present a methodology based on NOSF to optimize the nanofluid formulation for bacterial substrate removal and bulk inactivation. The results of this study will assist the food industry with the design of proper sanitation and will enhance microbial removal and inactivation strategies.

Show moreDrug delivery is an exciting field of interdisciplinary research that has captured the interests of the Pharmaceutical and Biotechnology industry. With the continual advances in discovery and synthesis of effective drugs, it is imperative to create safe and efficient drug-delivery systems. Biocompatible polymer nanoparticles are beginning to provide innovative solutions and form the frontier of advanced drug-delivery technology and Nanomedicine. Phosphate ions have been identified to be instrumental in healing wounds and preventing post-surgery gut-derived sepsis. We have developed a process of inverse miniemulsion polymerization to produce highly crosslinked, Biocompatible PEG diacrylate nanoparticles in the size range of 156-217 nm encapsulated with comprising phosphate ions. An aqueous solution containing high amounts of crosslinker (PEG diacrylate 575), NVP, phosphate salt and a water-soluble thermal initiator was emulsified in cyclohexane (oil-phase) by the application of high shear (ultrasound) to generate an inverse miniemulsion. The aqueous nano-droplets were stabilized against coalescence by the use for two non-ionic surfactants. The presence of phosphate salt within these stable nano-droplets prevented destabilization of the miniemulsion against Ostwald ripening. The encapsulation of phosphate within the nanoparticles is made certain by selecting a phosphate concentration dictated by the PEGDA-Phosphate temperature-dependent thermodynamics. Reported experimental measurements include monomer conversion, particle size measurement and aqueous swelling characteristics. Nanoparticle tracking Analysis (NTA) methodology developed by Nanosight Inc. was used for particle size measurements. A factorial design of experimentation coupled with the application of a xiii kinetic model indicate a low range (10-3 – 10-4) of the initiator efficiency in the reaction kinetics. The comparison of experimental conversion data with model predictions, points towards a well documented notion of a drastic reduction in initiator efficiency that once a critical degree of crosslinking is achieved within the nanoparticles during the reaction. The inverse swelling ratios (proportional to crosslink density) of the nanoparticles tend to substantiate the above kinetic behavior. The preliminary medical testing of the synthesized nanoparticles showed promising results indicating the efficacy of this strategy in drug delivery and regenerative tissue engineering.

Show moreDye-Sensitized Solar Cells (DSSCs) have been investigated using various methods including: varied illumination density, cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and equivalent circuit models. Under various illumination conditions, DSSCs were affected by many factors: exposure time, surrounding temperature, light intensity and UV (ultraviolet) radiation. In order to understand and identify aging phenomena, as well as ionic and electronic processes, a number of physical and electrochemical experiments were performed. The internal resistances among the components of DSSCs showed distinct features under different experimental conditions. For long-term stability and high performance of DSSCs, it is necessary to investigate the characteristics of these internal resistances and develop methods to reduce them. By using electrochemical impedance spectroscopy (EIS) and equivalent circuit models, it was possible to demonstrate the electrochemical phenomena and degradation characteristics of DSSCs.

Show moreThe ability to promote and control blood vessel assembly in polymer scaffolds is important for clinical success in tissue engineering. Often, experimental studies are performed to investigate the role of scaffold architecture on vascularized tissue formation. However, experiments are expensive and time-consuming and synthesis protocols often do not allow for independent investigation of specific scaffold properties. Mathematical and computational representation of the relationship between scaffold properties and neovascularization facilitates studying the fundamental processes involved in vascularization of biomaterials and provides more profound understanding of the critical factors that affect this process. This understanding is critical for the design of new therapeutic approaches that could bridge the existing gap between current experimental techniques and the state of the art practical tissue regeneration approaches. Computational models allow for rapid screening of potential material designs with control over scaffold properties that is difficult in laboratory settings. In this work, a multi-layered, multi-agent framework is developed to model the process of sprouting angiogenesis within porous biodegradable tissue engineering scaffolds. Software agents are designed to represent endothelial cells, interacting together and with their micro-environment, leading to formation of new blood vessels that perfuse the scaffold. A rule base, derived from the experimental findings reported in the literature, or observed by our collaborators, governs the behavior of individual agents. Two-dimensional and three-dimensional scaffold models with well-defined homogeneous and heterogeneous pore architectures are designed and simulated to investigate the impact of various scaffold design parameters such as pore size, pore size distribution, interconnectivity, and porosity, as well as the degradation behavior of 2 the scaffolds, on vessel invasion and capillary network structure. Model parameters such as the speed of vessel sprouting or cell migration speed are adjusted based on independent results of in vivo vascularization of fibrin gels in the absence of a polymer scaffold. The effects of various characteristics of scaffold degradation are also investigated. Various scenarios are defined and simulation case studies are developed to investigate the effect of scaffold geometrical and structural properties on angiogenesis. The simulation results are compared with available experimental results of scaffold vascularization performed in our group and with relevant published literature data to validate the developed model. These results indicate that in general the rate of vascularization increases with larger pore size and higher interconnectivity and porosity scaffolds. Pores of larger size (160-270 μm) support rapid and extensive angiogenesis, however vascularizing deeper parts of the scaffolds still remains a challenge that requires more complex scaffold designs. The agent-based model can be used to provide insight into optimal scaffold properties that support vascularization of engineered tissues. The modeling framework developed provides a novel interface for convenient integration of new knowledge to the current computational models, making it possible to gradually increase the level of complexity and accuracy of the models as our knowledge about the underlying biological system advances. The simulation results help us better understand the complex interactions between the growing blood vessel network and a degrading scaffold structure, and identify the optimal combinations of geometric and degradation characteristics of tissue engineering scaffolds that support scaffold vascularization.

Show moreIn electrochemical studies, the measured parameter (potential, current, or charge) is related to the quantity of the analyte in the solution and therefore can serve as an analytical signal for concentration measurements. The aim of this work is to develop high precision, real-time, quantitative, electroanalytical measurements of the concentrations of actinide chlorices in molten salts for monitoring pyrochemical process. Possible reasons for discrepancies found in the literature among electrochemically-measured values have been identified and methods to improve their precision have been established. Specific procedures were developed to refine both experimental techniques and data analysis methods. By following these procedures, precise and reproducible measurements were obtained for U and Pu in LiCl/KCl eutectic at 500°C. The effect of varying concentration on the method was investigated. In particular, the applicability of the techniques at high concentration of the analyte is evaluated. In addition to this, samples containing more than one analyte are considered, and the development of a modified data analysis method, required for their quantitative analysis, is described. Comparison of results obtained from improved electroanalytical measurements, and inductively coupled plasma atomic emission spectroscopy (ICP-AES) analysis, are shown and discussed. In addition to this, analysis of current-time transients, following a potential step, provide fundamental information about nucleation and growth of actinides on inert electrodes from molten salts. The effect of different concentrations of electroactive species, the applied potential, and the material of the working electrode on nucleation parameters are examined and discussed.

Show moreIn the context of real time electricity pricing, energy consumption by Heating, Ventilation, and Air Conditioning (HVAC) systems is usually heaviest when prices are at their highest. In order to reduce expenditure while adequately maintaining indoor comfort conditions, Economic Model Predictive Control (EMPC) policies can be implemented in conjunction with Thermal Energy Storage (TES). This equipment con guration allows the time-shift of chiller power consumption away from periods of high demand to periods of low energy cost. Overcoming the main drawbacks intrinsic to EMPC policies constitutes the initial focus of this work. The rst issue concerns the susceptibility of EMPC to disturbance prediction quality, as this algorithm relies on weather and electricity price forecasts to generate control actions. Thus, two gray box models of increasing complexity are developed to illustrate the fundamentals of disturbance forecasting with shaping lters. Additionally, two data driven models are also presented for comparison. The discussion is then expanded to forecasting quality based on the amount of information available, and proper economic evaluation of these scenarios with gray and black box models is performed. The second issue of interest is related to the susceptibility of EMPC to prediction horizon, since this methodology computes control actions based on a receding horizon framework. Usually, control policies that reduce expenditure the most also rely on relatively large horizon sizes. These implementations tend to result in considerable computational burden. While horizon size reductions are commonly used to lessen the associated computational needs, they also carry signi cant economic performance degradations. To solve this issue, a novel Economic Linear Optimal Control (ELOC) capable of enforcing constraints statistically is developed. Additionally, the ELOC feedback is used to generate a receding horizon formulation capable of enforcing point-wise-in-time constraints, termed constrained viii ELOC. This algorithm is virtually insensitive to horizon size while retaining and even surpassing the economic performance of EMPC. The third major achievement of this work is the development of an HVAC equipment sizing and optimization methodology. This goal is achieved through the implementation of a gradient search algorithm designed to predict returns on investment based on a net present value analysis. As part of this technique, the ELOC and constrained ELOC methodologies are expanded for equipment design. The successful implementation and convergence of this numeric optimization is illustrated with a case study.

Show moreEstimation of future glucose concentrations is a crucial task for diabetes management. Predicted glucose values can be used for early hypoglycemic/hyperglycemic alarms or for adjustment of insulin amount/rate. In the first part of this thesis, reliable subject-specific glucose concentration prediction models are developed using a patient’s continuous glucose monitoring (CGM) data. CGM technologies provide glucose readings at a high frequency and consequently detailed insight into a patient’s glucose variation. Time-series analyses are utilized to develop low-order linear models from a patient’s own CGM data. Glucose prediction models are integrated with recursive identification and change detection methods, which enable dynamical adaptation of the model to inter-/intra-subject variability and glycemic disturbances. Two separate patient data sets collected under hospitalized (disturbance-free) and normal daily life conditions are used to validate the univariate glucose prediction algorithm developed. Prediction performance is evaluated in terms of prediction error metrics and Clarke error grid analysis (CG-EGA). The long-term complications of diabetes can be reduced by controlling the blood glucose concentrations within normoglycemic limits. In the second part of this thesis, the subject-specific modeling algorithm developed in part one is integrated with a control algorithm for closing the glucose regulation loop for patients with type 1 diabetes. An adaptive control algorithm is developed to keep a patient’s glucose concentrations within normoglycemic range and dynamically respond to glycemic challenges with automated subcutaneous insulin infusion. A model-based control strategy is used to calculate the required insulin infusion rate, while the model parameters are recursively identified at each sampling step. The closed-loop algorithm is designed for the subcutaneous route for both glucose sensing and insulin delivery. xii It accounts for the slow insulin absorption from the adipose tissue and the time-delay between blood and subcutaneous glucose concentrations. The performance of the control algorithm developed is demonstrated on two simulated patient populations to provide effective blood glucose regulation in response to multiple meal challenges with a simultaneous challenge on a patient’s insulin sensitivity. Physical activity and emotional stimuli such as stress are known to have a significant effect on a patient’s whole-body fuel metabolism. In the third part of this thesis, the univariate time-series models developed from recent glucose concentration history are extended to include additional information on a patient’s physical and emotional condition. Physiological measurements from a multi-sensor body monitor are used to supplement a patient’s CGM data and develop multivariate glucose prediction models. The prediction performance of the multivariate algorithm developed is evaluated on data collected from patients with type 2 diabetes, and a real life implementation of the algorithm is demonstrated for early (i.e., 30 min in advance) hypoglycemia detection. Finally, the control algorithm developed in part two is extended to utilize the glucose profiles predicted by the multivariate patient model. The multivariate closedloop algorithm is tested with two clinical experiments performed on a patient with type 1 diabetes during a high intensity exercise followed by a carbohydrate-rich meal challenge. The algorithm acquires the patient’s CGM and armband (body monitor) data every 10 min, and accordingly calculates the required basal insulin infusion rate. Insulin is administered in a fully automated manner without any food or activity announcements (e.g., no information on meal/exercise size or time). None of the algorithms developed in this thesis require any patient specific tailoring or prior experimental data before implementation. They are also designed to function in a fully automated manner and do not require any disturbance announcexiii ments or manual inputs. Therefore, they are good candidates for installation on a portable ambulatory device used in a patient’s home environment for his/her diabetes management.
