Abstract:
Approximately 450 000 people have diabetes in Sweden today, and the number of diabetics only rises. Monitoring blood sugar several times a day is a fundamental part of managing the disease, and reducing the risks of complications. Today’s glucose monitoring devices are invasive and require small needle sticks for a measurement. Providing a painless method of monitoring the blood sugar level would relieve the lives of diabetics world-wide.   The objective of this project was to investigate the absorption spectra of aqueous glucose concentrations (100 to 5000 mg/dl) in the mid infrared region with Fourier Transform spectroscopy (FTIR), and finally implementing a hand-held monochromatic spectrometer to demonstrate a non-invasive concept. The method chosen for implementing the hand-held demo is due to the commercial availability of diodes and detectors at those wavelengths.   The results from the FTIR showed a trend among concentrations in all wavelengths, in between 1180 to 980 cm-1, specifically at 1035 cm-1, but also in the region 2920 to 2850 cm-1. The hand-held spectrometer did not register any transmittance of the glucose samples. For future implementations, 1035 cm-1 should be investigated more in-depth for a hand-held device.

Abstract:
This study focuses on the characterization of InAs and InAs1-xSbx epitaxial layers by infrared reflectance and transmittance spectroscopy and Hall measurements. Reflectance measurements were performed in order to obtain the dielectric parameters and to extract from these information about the electrical properties (mobility and carrier concentration) of this important III-V material system. The transmittance measurements were used to determine the bandgap of InAsSb. Infrared reflectivity and transmittance measurements were performed in the wavelength range 200 – 2000 cm-1 on InAs and InAsSb layers grown on three types of substrates. A classical two oscillator model that takes into account both the free carriers and the lattice, was used to analyse the reflectance data using the BMDP® computer curve fitting software. The dielectric parameters and the electrical properties (carrier concentration and mobility) were extracted from the simulations. Due to the low free carrier concentration in the epitaxial structures, the plasma resonance frequency (ωp) values obtained from the simulations of reflectance spectra measured above 200 cm-1, were in the order of 20-30 cm-1. These low values were confirmed by direct measurements of ωp in reflectance spectra obtained in the range 15-200 cm-1. The simulated carrier concentration and mobility values determined optically were compared to the values determined by Hall measurements at room temperature and previously reported values by other researchers. The simulated values obtained were in reasonable agreement with the Hall values. The simulated and measured carrier concentrations obtained for InAs layers were significantly higher than the intrinsic carrier concentration for InAs at room temperature, indicating notable concentrations of donors resulting from the growth process.

Full text
Abstract:
This work describes an investigation of the development of a Fourier Transform Infrared (FTIR) spectroscopic method for the determination of Solid Fat Index (SFI) of fats as a possible replacement of the traditional dilatometric procedure. The initial approach considered was the use of an existing FTIR analytical package which was designed to measure iodine value (IV), saponification number (SN), and cis and trans content. It was hypothesized that these measures could be related to SFI using multiple linear regression (MLR), thereby allowing the existing analytical package to simultaneously make SFI measures. It was found that there was a strong relationship between SN/cis/trans measurements and SFI, especially in sequentially hydrogenated oils. The MLR relationships, however, did not reproduce the dilatometric SFI values with sufficient accuracy in the general case, and this approach had to be abandoned. Subsequently, a partial least squares (PLS) calibration approach was investigated, relating the dilatometric SFI data directly to the spectral characteristics of the melted fats. It was found that suitable PLS calibrations could be developed for soybean and Canola oils. Based on these results, an FTIR system was programmed to determine SFI and the performance of the system validated using pre-analyzed "unknowns". It was shown that the SFI of either soybean or Canola oils could be determined to within $ pm$ 1.0 SFI. As configured, the FTIR system is capable of determining the SFI of a neat and clear, melted fat sample at 80$ sp circ$C in less than two minutes, providing four SFI values, representing the solids content at 50, 70, 80 and 92$ sp circ$F. In contrast to the standard dilatometric method, which takes over two hours to carry out, the FTIR approach provides a rapid means of determining SFI, the technique being suitable for routine quality control applications in the fats and oils industry.

Abstract:
New and rapid techniques for the characterization and identification of bacteria would have an important role in clinical microbiology and in food analysis because of an increasing prevalence of infectious diseases and In this work we carried out two approaches. In the first study the characterization and differentiation of mesophilic and thermophilic bacteria were investigated by using Fourier Transform Infrared (FTIR) Spectroscopic technique. In the second study, we investigated the characterization and identification of 3 Bacillus and Micrococcus species Our results from first approach show that there was a dramatic difference between mesophilic and thermophilic bacteria. The protein concentration was high, lipid concentration, the level of triglycerides and the unsaturated acyl chains decreased in thermophilic bacteria. We found that in thermophilic bacteria PO- 2 groups become hydrogen bounded. In addition, our results suggest that the cellular DNA content was low in thermophilic bacteria. Moreover there were characteristic peaks for both mesophilic and thermophilic bacteria and these peaks can be used for the differentiation of these two bacteria group. There were also some specific peaks that can be used for the differentiation of Escherichia coli and Lactobacillus plantarum at species level. In the second approach, our results show that there were significant spectral differences between Bacillus and Micrococcus species such as the proportion of unsaturated acyl chains in triglycerides were higher in Micrococcus species. Moreover we observed different bands that may be explained by an acetate oxidation via the tricarboxylic acid cycle and an exopolymer formation in Micrococcus species. In addition to that another band similar to glycogen, may be explained by a glycogen-like storage material in Micrococcus species. Also there are characteristic peaks that can be used for identification of Micrococcus spp.

Abstract:
COORDENAÇÃO DE APERFEIÇOAMENTO DO PESSOAL DE ENSINO SUPERIOR
Diversas propriedades físico-químicas de gasolinas (teores de álcool, benzeno, aromáticos, saturados e olefinas, densidade, MON, RON e temperaturas de destilação) foram estimadas simultaneamente por espectroscopia na região do infravermelho médio (FTIR) acoplada à regressão por mínimos quadrados parciais (PLS). Os métodos de referência utilizados incluíram métodos ASTM, ABNT e o equipamento IROX, baseado em espectroscopia na região do infravermelho próximo. Embora o erro médio da predição (RMSEP) tenha sido o principal parâmetro considerado para selecionar o melhor modelo de predição para cada propriedade, a repetibilidade e a reprodutibilidade também foram avaliados. As propriedades que tiveram como método de referência o equipamento IROX (todos os teores, MON e RON) apresentaram, em geral, resultados mais pobres, sendo o pior resultado o encontrado para o teor de olefinas (21,3 +- 2,4) e o melhor para MON (82,5 +- 0,5). No caso das propriedades que tiveram como referência métodos ASTM ou ABNT (teor de álcool, densidade e temperaturas de destilação) o pior resultado encontrado foi para o teor de álcool (23,9 +- 0,7) e o melhor para a densidade (0,7556 +- 0,0025). No entanto, mesmo quando os valores de RMSEP encontrados através da regressão PLS foram considerados pequenos, os coeficientes de correlação (R2) entre os valores preditos e os de referência, para um conjunto de amostras independentes da calibração, foram menores que 0,70, para todas as propriedades. Isso se deve, principalmente, a pouca variação nos valores de algumas propriedades, como MON, por exemplo, que em todas as gasolinas analisadas apresentou valores entre 81,4 e 83,8. Ainda assim, o método FTIR-PLS mostrou-se bastante promissor como uma alternativa para a análise de gasolinas, podendo ser melhorado com a utilização de maior número de amostras de calibração e/ou com a utilização de um conjunto de amostras mais representativo, além da utilização de métodos de referência padrão.
Several gasoline properties (alcohol, benzene, aromatics, saturated and olefin contents, density, MON, RON and distillation temperatures) have been predicted simultaneously by spectroscopy in the region of the mid infrared (FTIR) and partial least squares regression (PLS). The methods used as reference have included ASTM and ABNT methods and the IROX equipment, based on spectroscopy in the region of the near infrared. Although the standard error of the prediction (RMSEP) has been the main considered parameter to select the best model of prediction for each property, the repeatability and the reproducibility have also been evaluated. In general, the properties determined by IROX as the reference method (all the constituents, MON and RON) have presented poor results, the worst one found being the olefins content (21,3 +- 2,4) and the best one MON (82,5 +- 0,5). In the case of the properties that had ASTM or ABNT methods as reference (alcohol content, density and distillation temperatures) the worst results were found for the alcohol content (23,9 +- 0,7) and the best one for the density (0,7556 +- 0,0025). However, even values of RMSEP found by PLS regression had been considered small, the correlation coefficients (R2) between the predicted values and reference values, for a set of samples independent of the calibration, have been shown to be below 0,70, for all the properties. This fact can be explained by the small variation in the values of some properties, as MON, that in all gasoline samples presented values between 81,4 and 83,8. FTIR-PLS method revealed promising as an alternative for gasoline analysis. This method could be improved with the use of a greater set of calibration samples and/or with the use of a more representative sample set, beyond the use of standard reference methods.

Abstract:
The preparation of solid dispersions, in this study felodipine/polyvinyl pyrrolidone solid dispersion, is a multifaceted phenomenon. In order to understand the formation of solid dispersions two different mixed solvent system, three different temperatures and different drug loadings were selected and monitored in real time using Attenuated Total Reflectance-Fourier Transform Infrared Spectroscopy. 50 mul of the prepared solution was placed onto a pre-heated ATR crystal. The effect of PVP/API ratio, molecular interactions and effect of temperature (30°C, 40°C and 50°C) on the rate of film formation (solid dispersions) was evaluated. The changes in the peak positions, peak intensities and peak width as a function of time was monitored. The data were then analysed using peak height measurements, statistical and chemometric data analytical tools. It was shown that the nature of the solvent, the working temperature, presence of polymer and low drug loading was found to influence the rate of evaporation of solvent, molecular interactions and quality of the final product. Moreover, using thermogravimetric techniques it was complemented that the residual solvent within the systems was within the studied limits. The spatial arrangement or distribution of components within solid dispersion was found to influence the physical stability, phase behaviour, dissolution and bioavailability. Mid infrared spectroscopic imaging has been shown to be useful and has provided unique insights in to various fields. However, it has very limited applications in analysing the pharmaceutical materials. This work aims to evaluate various image processing tools in extracting process related information. Three model systems with varying chemical composition were selected. The chemical images from the regions of interest were collected using a Varian 620 FTIR Imaging instrument equipped with 64 x 64 MCT-Focal Plane Array (FPA) detector. Firstly we showed the impact of optical artefacts on the quality of the acquired image. The data was then pre-processed to remove baseline effects, pathlength variations and image processed to extract distribution maps. Agreement between the data generated using peak height measurements, compare correlation, principal component analysis and multivariate curve resolution was obtained only with the simple systems, the advantage with the latter being that the supervised and unsupervised chemometric approaches do not require any prior information about the sample and does not suffer from any physical or chemical interferences. The success of MCR-ALS over compare correlation and PCA methods is that it does not require any pure materials library and provides chemical information respectively. Moreover, implementation and data extraction is easy using MCR-ALS. It was then showed that once the optical artefacts are separated and chemically significant information is extracted, the benefits of infrared imaging was multitude. The optimised procedures were then applied to other samples to expand the applications of mid infrared imaging. There is no established paper to date describing the application of FTIR imaging to study the solvent induced phase separation in solid dispersions. One of the aims of this work is to study the impact of two different solvents on the phase behaviour of felodipine/polyvinyl pyrrolidone solid dispersions cast from different binary solvent systems. The temperature induced phase separation and degradation have been studied using differential scanning calorimetry, scanning electron microscopy, thermogravimetric etc, however we have shown the application of FTIR imaging in assessing the temperature induced degradation complemented and supported by in situ ATR-FTIR spectroscopy and thermogravimetric analysis.

Abstract:
Rapid detection of pathogens and hazardous elements in fresh fruits and vegetables after harvest requires the use of advanced sensor technology at each step in the farm-to-consumer or farm-to-processing sequence. Fourier-transform infrared (FTIR) spectroscopy and the complementary Raman spectroscopy, an advanced optical technique based on light scattering will be investigated for rapid and on-site assessment of produce safety. Paving the way toward the development of this innovative methodology, specific original objectives were to (1) identify and distinguish different serotypes of Escherichia coli, Listeria monocytogenes, Salmonella typhimurium, and Bacillus cereus by FTIR and Raman spectroscopy, (2) develop spectroscopic fingerprint patterns and detection methodology for fungi such as Aspergillus, Rhizopus, Fusarium, and Penicillium (3) to validate a universal spectroscopic procedure to detect foodborne pathogens and non-pathogens in food systems. The original objectives proposed were very ambitious hence modifications were necessary to fit with the funding. Elaborate experiments were conducted for sensitivity, additionally, testing a wide range of pathogens (more than selected list proposed) was also necessary to demonstrate the robustness of the instruments, most crucially, algorithms for differentiating a specific organism of interest in mixed cultures was conceptualized and validated, and finally neural network and chemometric models were tested on a variety of applications. Food systems tested were apple juice and buffer systems. Pathogens tested include Enterococcus faecium, Salmonella enteritidis, Salmonella typhimurium, Bacillus cereus, Yersinia enterocolitis, Shigella boydii, Staphylococus aureus, Serratiamarcescens, Pseudomonas vulgaris, Vibrio cholerae, Hafniaalvei, Enterobacter cloacae, Enterobacter aerogenes, E. coli (O103, O55, O121, O30 and O26), Aspergillus niger (NRRL 326) and Fusarium verticilliodes (NRRL 13586), Saccharomyces cerevisiae (ATCC 24859), Lactobacillus casei (ATCC 11443), Erwinia carotovora pv. carotovora and Clavibacter michiganense. Sensitivity of the FTIR detection was 103CFU/ml and a clear differentiation was obtained between the different organisms both at the species as well as at the strain level for the tested pathogens. A very crucial step in the direction of analyzing mixed cultures was taken. The vector based algorithm was able to identify a target pathogen of interest in a mixture of up to three organisms. Efforts will be made to extend this to 10-12 key pathogens. The experience gained was very helpful in laying the foundations for extracting the true fingerprint of a specific pathogen irrespective of the background substrate. This is very crucial especially when experimenting with solid samples as well as complex food matrices. Spectroscopic techniques, especially FTIR and Raman methods are being pursued by agencies such as DARPA and Department of Defense to combat homeland security. Through the BARD US-3296-02 feasibility grant, the foundations for detection, sample handling, and the needed algorithms and models were developed. Successive efforts will be made in transferring the methodology to fruit surfaces and to other complex food matrices which can be accomplished with creative sampling methods and experimentation. Even a marginal success in this direction will result in a very significant breakthrough because FTIR and Raman methods, in spite of their limitations are still one of most rapid and nondestructive methods available. Continued interest and efforts in improving the components as well as the refinement of the procedures is bound to result in a significant breakthrough in sensor technology for food safety and biosecurity.

Abstract:
Commercially available handheld chemical analyzers for forensic applications have been available for over a decade. Portable systems from multiple vendors can perform X-ray fluorescence (XRF) spectroscopy, Raman spectroscopy, Fourier transform infrared(FTIR) spectroscopy, and recently laser-induced breakdown spectroscopy (LIBS). Together, we have been exploring the development and potential applications of a multisensor system consisting of XRF, Raman, and LIBS for environmental characterization with a focus on soils from military ranges. Handheld sensors offer the potential to substantially increase sample throughput through the elimination of transport of samples back to the laboratory and labor-intensive sample preparation procedures. Further, these technologies have the capability for extremely rapid analysis, on the order of tens of seconds or less. We have compared and evaluated results from the analysis of several hundred soil samples using conventional laboratory bench top inductively coupled plasma atomic emission spectroscopy (ICP-AES) for metals evaluation and high-performance liquid chromatography (HPLC) and Raman spectroscopy for detection and characterization of energetic materials against handheld XRF, LIBS, and Raman analyzers. The soil samples contained antimony, copper, lead, tungsten, and zinc as well as energetic compounds such as 2,4,6-trinitrotoluene(TNT), hexahydro-1,3,5-triazine (RDX), nitroglycerine (NG), and dinitrotoluene isomers (DNT). Precision, accuracy, and sensitivity of the handheld field sensor technologies were compared against conventional laboratory instrumentation to determine their suitability for field characterization leading to decisional outcomes.

Abstract:
A new, commercially available, field-portable water sensor was evaluated for efficacy during operation and compatibility with current Environmental Toolkit for Expeditionary Operations (ETEO) software. The ETEO provides sensors to Soldiers to rapidly identify and quantify environmental contamination in soil, air, and water at potential new base sites during initial reconnaissance to ensure safety and minimize unnecessary remediation efforts by the Army. In addition to streamlined environmental baseline survey (EBS) reporting, the ETEO can provide rapid analysis of potential environmental contamination to support various Military applications. The Hanna Instruments HI9829 multiparameter water meter was selected following a survey of commercial off-the-shelf (COTS) technologies and analyzed by researchers from the US Army Engineer Research and Development Center (ERDC) for inclusion in the ETEO design since it can rapidly and accurately measure 14 different properties. Usability tests were conducted with researchers unfamiliar with the technology, and a set of standard operating procedures (SOPs) were developed to operate the device. The software for the tool was successfully integrated into the ETEO system for rapid data analysis. The HI9829 has been demonstrated in various scenarios at ERDC and other locations; including Ft. Leonard Wood, MO, at which several visitors reviewed the operation of the equipment and other ETEO technologies. The Thermo Scientific Gemini, another sensor, which can detect organic constituents in various matrices via Fourier transform infrared (FTIR) spectroscopy and Raman spectroscopy was also investigated but eliminated from the ETEO design as it could not adequately detect a Military-relevant compound in an environmental matrix. Regardless, the addition of the HI9829 provides water quality monitoring to the ETEO design and greatly improves its capability to address various applications.
