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 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.
