Investigation of Effect of KBr Matrix on Drift Infrared Spectra of Some Minerals

Diffuse Reflectance Infrared Fourier Transform (DRIFT) spectroscopy was used in this work to investigate the effect of KBr on infrared spectra of calcite and illite/smectite. 30 mg of each of these minerals were dispersed in 270 mg of KBr and their drifts spectra were obtained and analysed using OMNIC software. Same minerals samples were also run in DRIFT spectroscopy without being dispersed in KBr matrix and their spectra were obtained and analysed. After the investigation it was observed that minerals dispersed in KBr have spectra that are better than those run without KBr in terms of peaks resolution, repeatability and peaks height. Therefore, KBr played a vital role for better DRIFTS spectra which aid for the diagnosis of functional groups of different minerals useful during shale gas exploration processes.Keywords: Calcite, DRIFTS, illite/smectite KBr, Mineral sample

Absorption enhancement of plasmonic thin film solar cell combined with nanocavity

Plasmonic thin film solar cells have been given a lot of attention from researchers for their absorption capabilities. This study focused on the design of plasmonic thin film solar cell so that the absorption can be optimized. The structures were developed with different materials, geometries and configurations through Finite Element Method via COMSOL Multiphysics software. In order to validate the simulation method, comparison with the results from the previous research has been done first. The proposed design in this study is to build thin film solar cell with the combination of nanoparticle and nanocavity. Positioning gold nanoparticle in plasmonic thin film solar cell was demonstrated in various positions and nanoparticle near the surface has shown to be trapping more light. Semi-ellipse which used as nanocavity shape created an especial surface allowing more of the incident light was absorbed into the solar cell. From these results, the proposed design were structured by using indium tin oxide (ITO), silicon and aluminum as layers in the thin film solar cell with combination of nanoparticle and nanocavity. The result has shown remarkable positive change in absorption rate. The absorption rate for thin film solar cell with only ITO, silicon and aluminum layer has shown lower than thin film solar cell with these layers and the combination of nanocavity and nanoparticle. Detail from the results of this study will support future fabrication on solar cell

Quantitative analysis of a brass alloy using CF- LIBS and a laser ablation time-of-flight mass spectrometer

We present a quantitative analysis of a brass alloy using laser induced breakdown spectroscopy, energy dispersive x-ray spectroscopy (EDX) and laser ablation time-of-flight mass spectrometry (LA-TOF-MS). The emission lines of copper (Cu I) and zinc (Zn I), and the constituent elements of the brass alloy were used to calculate the plasma parameters. The plasma temperature was calculated from the Boltzmann plot as (10 000 ± 1000) K and the electron number density was determined as (2.0 ± 0.5) × 1017 cm−3 from the Stark-broadened Cu I line as well as using the Saha–Boltzmann equation. The elemental composition was deduced using these techniques: the Boltzmann plot method (70% Cu and 30% Zn), internal reference self-absorption correction (63.36% Cu and 36.64% Zn), EDX (61.75% Cu and 38.25% Zn), and LA-TOF (62% Cu and 38% Zn), whereas, the certified composition is (62% Cu and 38% Zn). It was observed that the internal reference self-absorption correction method yields analytical results comparable to that of EDX and LA-TOF-MS

Polyethylene oxide—fullerene nanocomposites

Polyethylene oxide – fullerene nanocomposites have been prepared by using the solution path with water as solvent (only for the polymer). The dispersion of C60 within the polymer solution was achieved by high power sonication. The study aims to a better understanding on the effect of C60 nanoparticles on the macromolecular chains. Raman Wide Angle X Ray spectroscopy, Differential Scanning Calorimetry, and Thermogravimetric Analysis were used to inspect the interactions between the nanofiller and macromolecular chains. The experimental results revealed a completely different behavior of fullerene dispersed within polymeric matrices than using carbon nanotubes or nanofibers as nanofiller. The observed behavior was explained by the low aspect ratio of C60 compared to nanotubes and by the low thermal conductivity of C60 compared to the thermal conductivity of others carbon nanostructures

E¡ect of lupin £our incorporation on the physical characteristics of dough and biscuits

Abstract Introduction: The incorporation of protein and dietary fibre rich lupin flour to biscuits has the potential to improve the nutritional value however it may adversely affect the physical and sensory properties. Objectives: To study the effect of lupin flour incorporation on the physical characteristics and sensory properties of biscuits to provide information to the potential manufacturers. Methods: Biscuit samples were prepared by substituting wheat flour with lupin flour at 0-50% levels. The samples were analysed for changes in dimensions, colour, texture and sensory properties. Results: Incorporation up to 40% level had no significant effect on biscuit diameter but thickness increased at Z 20%. No change in the L à values of dough and biscuits at 20% substitution. The a à values of dough decreased with increase in lupin flour concentration but in biscuit no significant change was observed up to 20% substitution. The b à values demonstrated a significant increase at 20% substitution. Biscuit hardness and fracturability demonstrated an increase with the increase in lupin flour concentration at Z 20%. Sensory evaluation revealed an improvement in colour with lupin flour substitution with no significant changes in taste, flavour, texture and overall acceptability up to 20% substitution. Conclusion: Lupin flour can be successfully incorporated into biscuits by replacing up to 20% of wheat flour to increase protein and dietary fibre contents

Faba bean (Vicia faba L.) seeds darken rapidly and phenolic content falls when stored at higher temperature, moisture and light intensity

Faba beans cv. Fiesta with seed moisture content (SMC) modified to 8, 10, 12 and 14% were packed in polyethylene lined aluminium foil bags and stored at 5, 15, 20, 25, 30, 37, 45, 50 or 60 C ( 2 C) for one year. Samples were analysed for moisture content and seed coat (testa) colour over the storage period using a chroma meter. A continuous increase in L* and b* values was found in all samples with the passage of time whereas a *values first increased and then decreased in samples stored at relatively high temperatures (= 37 C). The initial beige testa colour changed to light brown, dark reddish brown or almost black depending on storage conditions. The higher the temperature and SMC the faster the rate of change in colour (E ab* values). Seeds with 8% SMC had more stable testa colour compared to seeds with higher SMC. Exposure to artificial light (350 mol m -2 s -1) substantially accelerated the colour darkening. Cotyledon stored at 37+2 C also darkened with the storage time. A loss in total free phenolics, total tannins and proanthocyanidins was found with increased darkness of testa and cotyledons during storage
