Abstract:
This research was initiated after a 100-year flood caused an oil spill on the San Jacinto River (Houston, Texas) in October of 1994. After the floodwaters subsided the released petroleum floating on the water was deposited on the surrounding lands. The petroleum spill was used as an opportunity to research intrinsic petroleum biodegradation in a 9-acre petroleum impacted estuarine wetland. The first phase of this research (Phase I) began in December 1994, approximately 1.5 months after the spill of opportunity and involved the study and quantification of in-situ petroleum biodegradation. The second phase of the research (Phase II) began in March 1996 with a controlled oil release to study and evaluate the success of two bioremediation treatments versus natural biodegradation. The study of in-situ petroleum hydrocarbon degradation and the evaluation of bioremediation amendments were successfully quantified using GC-MS analytical techniques. However, the GC-MS technique is limited to the analyses of hydrocarbon compounds, a disadvantage that precludes the overall characterization of petroleum degradation. The research presented here details an analytical technique that was used to provide a full characterization of temporal petroleum biodegradation. This technique uses thin layer chromatography coupled with flame ionization detection (TLC-FID) to characterize the saturate and aromatic (hydrocarbon) fractions and the resin and asphaltene (non-hydrocarbon, polar) fractions. Other analysis techniques, such as HPLC-SARA analysis, are available for the full characterization of the four petroleum fractions. However, these techniques do not lend themselves well to the application of large sample set analysis. A significant advantage of the TLC-FID analysis to other petroleum analysis techniques is the ability to analyze several samples concurrently and quickly with relative ease and few resources. For the purposes of the Phase I and Phase II research the TLC-FID analysis method was evaluated, refined and applied to quantify the temporal biodegradation and bioremediation of petroleum. While the TLC-FID analysis produces a full characterization, it cannot supplant the GC-MS analysis for petroleum bioremediation research. However, it can be used in conjunction with the GC-MS to expand the knowledge of petroleum bioremediation and remediation strategies.

Abstract:
The purpose is to isolate a natural compound, which shows a high activity against Candida albicans, from plant, Vincetoxicum stocksii. Bio-Assay, Thin layer Chromatography, Column Chromatography, TLC bio Assay, and other extraction techniques are used in order to isolate the active compound. First, bio assay technique is carried out on the crude gum. Next, several flash chromatography columns are carried out in order to isolate the target compound, which has a Rf value of ~0.53 in 10:1 DCM/methanol solvent mixture. The TLC bioassay technique is also carried out in order to confirm the hypothesis that the target compound is indeed active.

Abstract:
A sol-gel stationary phase was developed for in-situ infrared (IR) detection of analytes on thin-layer chromatography (TLC) plates. These sol-gel-based TLC plates have improved optical properties compared with conventional TLC plates in IR spectroscopic analysis. Samples can be analyzed in transmission geometry, requiring no special attachments. The sol-gel-based TLC plates demonstrate significantly better light throughput and a wider spectral range than conventional TLC plates analyzed in diffuse reflectance geometries.The sol-gel precursor, methyltrimethoxyorthosilicate (MTES), was templated with cetyltrimethylammonium bromide (CTAB) and urea in order to form a porous sol-gel. Aerosol deposition was used to apply the sol-gel solution onto either glass slides or silicon wafers within an enclosed chamber. Many variables were studied to determine their effect on the quality of the sol-gel stationary phases, including the ratio of MTES:methanol:water:CTAB:urea:HCl:, gelation times and temperatures, and deposition rate. Sol-gel films prepared using MTES/methanol/water/CTAB at ratios of 1 : 20 : 7 : 0.2 containing 5 wt% urea (relative to MTES) and pH 1.5 were crack-free, mechanically stable, and uniform in appearance. The films were tens of microns thick with a highly interconnected porous structure.For chromatographic separations, the films exhibited good solvent migration velocity and could be repeatedly washed and reused for TLC separations without showing degradation in the separation. Several different classes of compounds, including polyaromatic hydrocarbons and dyes, were successfully separated. Theoretical plate values measured on the MTES-based sol-gel films were comparable to those obtained on commercially available TLC plates.

Abstract:
Surfaces that exhibit a gradual change in their chemical and/or physical properties are termed as surface gradients. Based on the changes in properties they are classified either as physical or chemical gradients. Chemical gradients show variations in properties like polarity, charge, functionality concentration and have found potential applications in fields of biology, physics, biosensing, catalysis and separation science. In this dissertation, surface gradients have been prepared using controlled rate infusion (CRI). CRI is a simple method in which a surface gradient is formed by carrying out the infusion of organoalkoxysilane in a time-dependent fashion using a set infusion rate. Depending on concentration of silane, rate of infusion and time of infusion, the gradient profiles on surfaces can be varied and the surface chemistry of the substrate can be altered. Initial work in the dissertation focuses on demonstrating different gradient profiles and selectivity obtained using amine and/ or phenyl functionalized gradient stationary phases on thin layer chromatography (TLC) plates prepared by CRI. The presence of amine and phenyl on the surfaces were confirmed by X-ray Photoelectron Spectroscopy (XPS) and diffuse reflectance spectroscopy, respectively. The change in surface chemistry was demonstrated by changes in the selectivities of water and fat soluble vitamins. After successful preparation and characterization of single and multi-component stationary phase gradients for planar chromatography, single-component gradients were prepared for column chromatography (Silica monolithic columns). Similar to that observed for planar chromatography, the selectivity was evaluated from retention factors and was found to be different for a weak acid/weak base mixture. The results obtained showed the promising approach of using gradient stationary phases in column chromatography. This work was further extended to prepare amine and phenyl multi-component gradients on silica monolithic columns to investigate mixed-mode and synergistic effects. Finally, amine, phenyl and thiol gradients were also prepared on cellulose substrates, particularly water color paper, The goal was to study the formation of functionality gradients on cellulose substrates particularly the interaction between hydroxyl groups on cellulose and silanols and to study the stability of the silanes on the cellulose surface.

Full text
Abstract:
Gradient surfaces exhibit a variation in functionality along the length of the surface. One method for preparing gradients is controlled-rate infusion (CRI). In Part 1 of this work, CRI was used to prepare gradients for the purpose of separating transition and heavy metals. Initial work on this project was focused on controlling the retention of the metal ions by varying the number of amine groups, aminoalkoxysilane concentration, and the infusion time. The retention factors of four metal ions varied predictably with increasing number of amine groups, increasing aminoalkoxysilane concentration, and increasing infusion time, producing small but useful changes in the retention factors. The continuation of this project involved the preparation of two-dimensional multi-component gradients on TLC plates, which were used to separate six transition and heavy metals. The retention, and thus the separation, was affected by the presence or absence of a gradient and the direction of the gradient. Part 2 of this work focused on understanding the factors that motivated instructors in the early and late stages in the process of change. Instructors who attended the POGIL-PCL (Process-Oriented Guided Inquiry Learning in the Physical Chemistry Laboratory) workshops were asked to complete online surveys. The goals of the first survey were to understand the factors that initially interested instructors in POGIL-PCL, to determine if instructors enter the implementation stage, and to understand the factors that affect how instructors implement POGIL-PCL. Later surveys were designed to explore the development of the POGIL-PCL network and assess whether implementation is sustained over time.

Abstract:
Cannabidiol (CBD) is an alkaloid present in Cannabis sativa, together with tetrahydrocannabinol (THC) and more than 120 other substances belonging to a group of compounds named cannabinoids. Due to the continuous increased usage of CBD oils, it became necessary to be developed efficient methods for the identification of its compounds and especially for the characterization of the cannabinoids from the commercial specimens. Cannabinoids may be detected by many and different analytical methods, including immunoassays (EMIT®, Elisa, fluorescent polarization, radioimmunotest), techniques of flat chromatography: classic thin layer chromatography (TLC), optimum performance laminar chromatography (OPLC) and multiple development automatization (AMD), gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography-mass spectrometry (HPLC-MS). Ultraviolet signal (UV) is used for the quantification of major cannabinoids and the mass spectrometer is used for the quantification of minor cannabinoids. The purpose of this study was to compare the performances of TLC, Ultra High-Performance Liquid chromatography with Photodiode Array Detection (UHPLC with PDA) and LC-MS/ MS technique for the qualitative and quantitative determination of cannabinoids in 3 commercial oils with CBD. Having in view that CBD may be found in many forms of oils, on the legal market of the internet, we believe that the development of a method for the qualitative and quantitative determination may be an interesting subject for the pharmaceutical professional persons.

Abstract:
Accumulation of lipids in the intimal arterial layer, and of cholesterol esters in particular, has been recognised as an early and prominent phenomenon in atherogenesis. Several attempts have been made to link putative peroxidation of these lipids in vivo to causal or deteriorating etiological determinants of plaque formation. The occurrence in advanced human atheromata of oxidized derivatives of cholesteryl linoleate -a major polyunsaturated cholesterol ester species in plasma and vessel wall - has been described by Brooks et al. (Atherosclerosis, 1970,13,223) and a positive correlation between the amount of cholesteryl hydroxyoctadecadienoates (CHODES) and the stage of the lesion has also been reported. In addition Funk and Powell (J. Biol. Chem., 1985,260,7481) have found hydroxyoctadecadienoic acids in normal aorta of different species, wich were strikingly increased after alkaline hydrolysis of total lipids, and this in contrast with the arachidonic acid analogs. The aim of this study was to develop a sensitive and practical method for specific assay of CHODES, without resorting to laborious saponification and derivatisation procedures required for gas chromatographic analysis, which could moreover augment the risk for artefacts.Dog thoracal aorta was homogenised and lipids were extracted using the Folch method with CHCl3/CH30H;2/l containing 0.05mM butylated hydroxytoluene. Fractionation of CHODES from neutral lipids was carried out by thin-layer chromatography. For detection and quantification a high-performance liquid chromatography (HPI/2) assay method was developed, with UV monitoring at 232nm , a wavelength characteristic for conjugated dienes with vicinal hydroxyl function. Reference compounds and the internal standard for HPLC analysis were synthesized from linoleic acid and 10,13,16-docosatrienoic acid, respectively, by preparation of hydroxy fatty acids with soybean lipoxygenase and subsequent esterification to cholesterol esters with pancreas cholesterol esterase. Confirmation of the structural identity was obtained by mass spectrometry. Artefactual formation of CHODES ex vivo was investigated by subjecting radiolabeled cholesteryl linoleate through the analysis procedure. This method allows the specific detection of CHODES in non-atherosclerotic arteries which was hitherto only reported for human advanced atherosclerotic lesions and is proposed as a sensitive and specific probe for prospective survey of lipid peroxidation in atherosclerotic blood vessels.
