Abstract:
The physicochemical properties and potential hemostatic application of Wenchang kaolin and Maoming kaolin were inspected and evaluated. Chemical composition analysis, Fourier transform infrared (FTIR) spectroscopy, surface area determination, X-ray diffraction, particle size, scanning electron microscopy (SEM) observations, and zeta potential analysis were performed to quantify the physical and chemical properties of the two kaolins. The results showed that both kaolins have typical FTIR bands of kaolinite with a weight fraction for kaolinite over 90 wt%. Larger conglobate aggregates of Maoming kaolin demonstrated wider particle size distributions with two peaks at 3.17 and 35.57 μm, while the book-like Wenchang kaolin had narrow particle size distribution, with a frequent size of 5.64 μm. Furthermore, thrombelastography, the whole blood clotting tests (WBCT), plasma recalcification time (PRT) measurement, and MTT assay were performed to measure the clotting activities and biocompatibility of the two kaolins. The results showed that both kaolins could promote blood coagulation with good cytocompatibility, while Wenchang kaolin had a better procoagulant activity than Maoming kaolin. These findings demonstrated Wenchang kaolin to be a more suitable local source material for application as a hemostatic agent.

Abstract:
Abstract This study examines the mineral composition and kaolinite crystallinity of Cretaceous and Paleogene/Neogene kaolins from Nigeria based on X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy data of the <2 μm fraction. The purpose of this was to assess the minerals present, structural order, and possible industrial applications of the kaolins. A total of twenty-eight (28) samples comprising of fifteen (15) Cretaceous and thirteen (13) Paleogene/Neogene kaolins were analysed. The XRD results showed that both the Cretaceous and Paleogene/Neogene kaolins have kaolinite as the dominant phase followed by quartz with anatase, hematite, and goethite occurring in minor quantities. Based on the mineralogical composition, the Paleogene/Neogene deposits were classified as sandy kaolin and the Cretaceous deposits were classified as pure kaolin. The kaolinite structural order for the Cretaceous pure kaolin was higher than that obtained for the Paleogene/Neogene sandy kaolin with more quartz, iron, and titanium oxides. The economic consideration of the deposits showed that the sandy kaolin type can be used in pigment industrial applications whereas the pure kaolin type can be used in refractory, fiberglass, and ceramic industrial applications.

Abstract:
AbstractAccording to multivariate analysis, the following were established (a) kaolinite crystallinity index (KCI) values determined by XRD are highly correlated to one another and seemingly influenced by kaolin impurities; (b) kaolin minerals are concentrated mainly in the fractions <4 µm; (c) the kaolin surface area as determined by the BET (nitrogen adsorption) method is more markedly affected by kaolin impurities than by kaolin minerals themselves; (d) BET surfaces increase when kaolinite crystallinity decreases; (e) brightness is inversely correlated with kaolin impurities; (f) the more ordered the kaolinite and the greater the proportion in the <4 µm fraction of the kaolin, the greater the brightness; and (g) KCI values are particle size-distribution dependent for sedimentary-residual kaolins. The correlations obtained were better when kaolins were selected according to their origin because the kaolin minerals and their impurities, particle size-distribution and texture were more alike. The industrial properties of kaolin can not be predicted from other basic properties such as mineralogy, KCI, etc., because they are intricately related to one another.

Abstract:
Two widely different kaolin deposits were investigated in order to determine their physical and chemical properties and suggest their possible utilization. Kaolin deposits from Leucogia area, NE Greece, were formed in situ by weathering of gneissic rocks under a temperate climate; they consist largely of halloysite exhibiting different morphological forms, and stacks and plates of kaolinite in various proportions. The kaolin occurrences of Kos island are products of hydrothermally altered rhyolitic rocks of Pliocene age. The highly altered samples contain dickite and kaolinite. Testing included particle size distribution, brightness and whiteness, measurement of CEC (cation exchange capacity) and some ceramic properties including Atterberg limits. The CEC values range between 3.8-8 meq/100 g and 0.8-2.2 meq/100 g for kaolin samples from Leucogia and Kos island respectively and reflect the differences in clay mineralogy and the characteristic kaolin mineral present. Platy halloysite enhances CEC in Leucogia kaolins while kaolinite-rich samples in Kos exhibit higher CEC values than dickite-rich samples. Atterberg limit tests reveal the Leucogia and Kos kaolins to be of low to medium plasticity and to be classified in the category of kaolinitic clays suitable for brick making. The Leucogia kaolin shows relatively higher brightness (47-60%) and whiteness (62-77%) than Kos kaolin (41-48% and 61-66% respectively). These properties are influenced by the type of kaolin mineral present, their relative proportions and the FeaCb content of the samples. The obtained values for brightness and whiteness from both areas are lower compared to the standard commercial kaolins for the paper and filler market. Brightness, however, can be improved by fine grinding and refinement. The physical, chemical and mineralogical properties of Leucogia and Kos kaolins indicate that they are of low grade type. However, kaolin processing from the crude state can optimize some of these highly commercial properties

Abstract:
AbstractHigh-quality kaolins are produced from two sites in the Capim River area in Pará State, northern Brazil. One mine is operated by Rio Capim Caulim (RCC) owned by Imerys and the other by Pará Pigmentos S.A. (PPSA) owned by Caemi (CVRD Group). The kaolin deposits are located on low-relief plateaux with a lateritic cap. The kaolin strata are in the Ipixuna Formation of Upper Cretaceous Age. There are two distinct kaolin layers, a 4–5 m thick soft kaolin which is overlain in the southern portion of the basin by a 4–5 m thick hard kaolin. The soft and hard designations refer to particle size, with the soft kaolin being relatively coarse and the hard kaolin very fine. The kaolin is mined, partially beneficiated, and pumped through pipelines to the port at Barcarena on the Guama River, a large tributary of the Amazon River. The PPSA kaolin is fully processed at the plant near the mine site and pumped to Barcarena where it is spray dried. The RCC kaolin is only partially processed at the mine site. This partially processed kaolin is pumped to Barcarena where it is beneficiated. The finished kaolin is high quality and is shipped to North and South American, European, and Asian paper-coating markets. More than 1.6M tons were shipped from Barcarena in 2005.

Abstract:
The aim of the present study was the paleoenvironmental reconstruction of the prevailing environment under which the Lwamondo and Zebediela kaolin deposits were formed. Hence, this study reports deuterium and oxygen stable isotope values and trace and rare earth element concentrations for two samples of kaolin. Upper continental crust-normalised trace-element patterns reveal that large ion lithophile elements and high-field-strength elements are generally depleted in Lwamondo and Zebediela kaolins, whereas transition trace elements are generally enriched in these kaolins. Upper continental crust-normalised rare earth element (REE) patterns show that there is a slight enrichment of heavy REEs (HREEs) compared to light REEs (LREEs) in these kaolins. The δ18O and δD stable isotope values for kaolinite from Lwamondo ranged from 17.4‰ to 19.1‰ and from −54‰ to 84‰, respectively, whereas those values for kaolinite from Zebediela varied from 15.6‰ to 17.7‰ and from −61‰ to –68‰ for δ18O and δD, respectively. The REE patterns and the content of other trace elements indicate ongoing kaolinitisation in the Lwamondo and Zebediela kaolins with minimum mineral sorting. The sources of the kaolins varied from basic to acidic and these were derived from an active margin tectonic setting. Lwamondo kaolin was deposited in an oxic environment whereas Zebediela kaolin was deposited under suboxic/anoxic conditions. Based on the δ18O and δD values of the kaolinite, they formed in a supergene environment at temperatures generally below 40 °C.

Abstract:
Ceramic membrane has gained increasing interest in water filtration application due to its inherent characteristics. Low-cost clay materials are preferred to fabricate an efficient and cost-effective ceramic membrane. Among the ceramics, kaolin displays better mechanical, thermal, and chemical properties. However, natural properties of kaolin vary from different studies. Hence, cost-effective Nigeria (NK) and Malaysia (MK) kaolins were compared to study the fabrication of kaolin hollow fiber ceramic membrane for filtration application. The effects of kaolin loading concentration (34 and 37 wt. %) and sintering temperature (1200, 1350, 1400, and 1500 °C) on kaolin membrane fabrication were also studied. XRF studies indicated that the hydroxyl silica and alumina compositions were 56.76wt.% and 41.97wt% for NK and 55.21wt.% and 40.33wt% for MK. MK exhibited intense kaolinite peak with a broad range of particle size distribution. The mechanical stability of kaolin ceramic membrane increased with the increase of sintering temperature and kaolin loading concentration. Membrane morphology also varied with MK and NK. Interestingly, 34wt% kaolin at a sintered temperature of 1350 °C produced ceramic membrane with a high water flux. A similar trend was observed in both MK and NK, where the flux of 34wt% MK and NK are 565 and 460 L/m2h, respectively.

Abstract:
Kaolin is a white clay, formed by hydrated aluminum silicates, which has several industrial applications. Since it is associated to impurities and presents considerable contents of contaminant elements that interfere in its performance and in its applications, kaolin must pass through a beneficiation process in order to meet the market's demands. The purpose of this work is to study the use of a hydrocyclone in the beneficiation of primary kaolins from Província Pegmatítica da Borborema. The samples were characterized by cation-exchange capacity (CEC), granulometric analysis by laser diffraction (GA), chemical composition by X-ray fluorescence (EDX), X-ray diffraction (DRX), differential thermal analysis (DTA) and thermogravimetric analysis (TG). The purification process did not show good results for kaolin in ABNT 200 mesh in the attempt to obtain colloidal kaolin. On the other hand, it presented very promising results for the beneficiation of raw kaolin, proving the feasibility of the application of this technology to the granulometric classification of this mineral, being an alternative route for the processes adopted in the regional kaolin beneficiation plants, which use washing and sieving.

AbstractThe dynamic effects of kaolin clay particle film application on the temperature and spectral reflectance of leaves of two autochthonous cultivars (Touriga Nacional (TN, n=32) and Touriga Franca (TF, n=24)) were studied in the Douro wine region. The study was implemented in 2017, in conditions prone to multiple environmental stresses that include excessive light and temperature as well as water shortage. Light reflectance from kaolin-sprayed leaves was higher than the control (leaves without kaolin) on all dates. Kaolin’s protective effect over leaves’ temperatures was low on the 20 days after application and ceased about 60 days after its application. Differences between leaves with and without kaolin were explained by the normalized maximum leaf temperature (T_max_f_N), reflectance at 400 nm, 532 nm, and 737 nm, as assessed through TN data. The wavelengths of 532 nm and 737 nm are associated with plant physiological processes, which support the selection of these variables for assessing kaolin’s effects on leaves. The application of principal component analysis to the TF data, based on these four variables (T_max_f_N and reflectances: 400, 532, 737 nm) selected for TN, explained 83.56% of data variability (considering two principal components), obtaining a clear differentiation between leaves with and without kaolin. The T_max_f_N and the reflectance at 532 nm were the variables with a greater contribution for explaining data variability. The results improve the understanding of the vines’ response to kaolin throughout the grapevine cycle and support decisions about the re-application timing.

Mestrado em Engenharia de Materiais
A deposição eletroforética (EPD) é uma técnica interessante do ponto de vista de processamento de materiais permitindo a formação de filmes dos mais variados materiais em diferentes substratos condutores. É uma técnica simples, versátil e de baixo custo associado. No presente trabalho, conduziram-se estudos que permitiram estabelecer as condições apropriadas para a produção de filmes espessos de caulino por EPD. Depositaram-se filmes de caulino em verde, com cerca de 5 mg, em três tipos de substrato: aço inoxidável, folha de platina e silício platinizado. Para a identificação das condições de deposição, contribuiu o estudo sistemático das condições de preparação da suspensão de caulino que incluíram a avaliação do potencial zeta de suspensões com o pH da mesma, do efeito da composição do meio suspensor (água, etanol, ou mistura de ambos), do recurso ao iodo como aditivo, e da variação com o tempo da transmitância da luz UV por parte dos diferentes meios suspensores, com ou sem iodo. Os resultados obtidos permitiram concluir que as melhores condições de deposição são as que combinam a adição de alguma água ao etanol, enquanto meio suspensor, e o uso de iodo como aditivo. Os filmes preparados por EPD foram sinterizados a 1200 e 1300 oC, durante 2 h. A microestrutura dos filmes, antes e após sinterização, observada por microscopia eletrónica de varrimento (SEM) permitiu concluir que as partículas de caulino tendem a depositar de uma forma orientada em que as suas superfícies basais se alinham paralelamente ao substrato. Os filmes de caulino sinterizados foram submetidos a ensaios de nanoindentação e determinou-se a sua dureza Vickers e módulo de Young para os quais se obtiveram, respetivamente, 300 MPa e 40 GPa. Este trabalho contribuiu para identificar condições para obter filmes espessos de caulino de cuja a microestrutura anisotrópica se aponta a possibilidade de aceder a propriedades maximizadas segundo determinadas direções o que do ponto de vista das suas aplicações pode abrir novas oportunidades.
Electrophoretic deposition (EPD) is an interesting technique from the point of view of materials processing. The technique allows the formation of films of many different materials on different conductive substrates. Besides that, EPD is a simple, versatile and low cost technique. The studies conducted, in the present work, allowed the establishment of appropriate conditions to produce kaolin thick films by EPD. Green kaolin films with around 5 mg were deposited on three types of substrate: stainless steel, platinum foil and platinized silicon. A systematic study about the preparation conditions of the kaolin suspension contributed to identify the deposition conditions. This study included the assessment of the pH dependence of zeta potential of the suspension and the effect of the suspension media (water, ethanol or a mixture of both) as well as the use of iodine as additive. Transmittance variation of the UV light with time was also assessed for the different suspension media with and without iodine. The obtained results allowed to conclude that the best deposition conditions are those that combine the use some water in the ethanol based suspension media added also with iodine. The kaolin films produced by EPD were sintered at 1200 and 1300 oC for 2 h. The observation of the films microstructure by scanning electron microscopy (SEM), before and after sintering, allowed to conclude that the kaolin particles tend to deposit in an oriented way in which their basal surfaces align parallel to the substrate. The sintered kaolin films were submitted to nanoindentation tests and their Vickers hardness and Young’s modulus was determined as 300 MPa and 40 GPa, respectively. This work contributed to identify the conditions to obtain kaolin thick films of which the anisotropic microstructure is expected the possibility of assessing maximized properties under certain directions. From the point of view of applications, this can open new possibilities

Abstract:
With the aim to achieve a better understanding of the time-dependent behaviour of structured clays, especially cemented clay, a critical review of the literature and a programme of laboratory testing have been carried out. In order to investigate the time effects on different structured clays, a series of advanced triaxial and oedometer tests were conducted on reconstituted pure kaolin (PK), artificially cemented kaolin (ACK) with different curing periods, and remoulded artificially cemented kaolin (RACK). Strain rate effects were examined in pure kaolin with different degrees of over-consolidation in both undrained and drained shearing. The influence of bond structure on the monotonic stress-strain behaviour of cemented kaolin was investigated on specimens prepared with two different curing stress and curing periods. Tests on pure kaolin and remoulded cemented kaolin were also performed. Strain rate effects on long cured cemented kaolin under low and high confining stresses, with constant rate of straining in pre-peak stage and step-wise change rate of straining in post-peak stage were examined. This was completed by a study of the microstructure of pure kaolin and cemented kaolin specimens before and after tests via scanning electronic microscope. The coupling between stress or strain rate and curing time effects was investigated on cemented kaolin cured for shorter periods. The results have added significant data to the existing database and addressed the relationship between bond structure and time effect. The main conclusions are: ••The viscous type of PK determined is characterized as decaying positive isotache and General TESRA in undrained and drained shearing repectively. The strain rate history does not affect the critical state in both q-p’ and v-ln p’ spaces. ••The addition of cement not only creates new inter-particle bonds but also affects new fabric. The shear strength is dominated by bond structure under low confining stress, and by volume change under high confining stress. ••The viscous type of long-term cured ACK is dependent on the degree of bond structure. It is almost insensitive to strain rate changes when the specimen is stiff, and the apparent “aging” effect dominates resulting in a “negative” rate effect when bond structure is destroyed. A special rate phenomenon called stick-slip seems to occur under the lowest strain rate (0.01%/h) during the pre-peak stage. The RACK shows a TESRA type of viscosity in undrained shearing. ••The short-term cured ACK, in which structuring and rate effects are combined, shows negative rate effects due to the curing under low confining stress and apparent aging under high confining stress. Stick-slip occurs both in pre-peak and post-peak stages, due to different reasons.

Abstract:
The need for an improved understanding of the effects of temperature on the hydro-mechanical behaviour of compacted clays is important in many applications, such as disposal of high level nuclear wastes, burial of high voltage cables, drilling of deep offshore wells, and clay liners used on landfills. In this thesis, a study of the thermo-hydro-mechanical (THM) behaviour of kaolin clay under different conditions is presented. A series of experimental unsaturated tests was carried out, including temperature and suction controlled oedometer tests, and suction measurements to obtain the soil water retention curves at different temperatures. In order to describe the dependency of the soil water retention curves on temperature, the influences of temperature on the contact angle of menisci and the microstructure of the soil samples were studied. Moreover, Environmental Scanning Electron Microscopy was employed for studying the microstructure of the soil at certain conditions of interest. A new suction and temperature controlled oedometer cell was designed, developed and calibrated for investigating THM behaviour of kaolin clay. The oedometer was used to examine the combined effects of suction and temperature on compressibility and collapse behaviour of the soil. In this thesis, special attention was given to the filter paper methodology for suction measurements at different temperatures. The calibration curve of Whatman No. 42 filter paper was determined at 10, 25 and 50ºC using the vapour equilibrium technique with sodium chloride solutions at different concentrations and the axis translation technique. Based on the experimental data, a unique calibration equation was proposed; taking into account the effect of temperature. The experimental results showed that temperature has a relevant influence on filter paper suction measurement and that misleading results can be obtained if temperature is not taken into account in the calibration equation.

ENGLISH ABSTRACT: Sunburn is a major problem in the apple industry worldwide. A kaolin product, M-97- 009 (100% kaolin), originally developed for insect control, was evaluated for its efficacy in controlling sunburn on pome fruit. Trials were conducted over two seasons in two different areas of the Western Cape, South Africa. During the first season, 'Royal Gala', 'Fuji' and 'Granny Smith' apples were evaluated in the Koue Bokkeveld. The kaolin was mixed with water and applied to the trees by means of a hand-gun regularly throughout the season. In addition to the effect on sunburn, effects on yield, colour development, snout beetle damage and other defects were determined. Sunburn was reduced on all the cultivars tested, although not significantly on 'Granny Smith'. Inconsistent effects on yield parameters were observed. The applications significantly reduced red colour on 'Fuji', but this problem was rectified by an improved application technique the following season. During the second season, additional apple cultivars and 'Rosemarie' pears were included in the trials. The apple trials were conducted in the Elgin area, and the 'Rosemarie' trial in the Koue Bokkeveld. Surround™ (95% kaolin) was applied to the trees by means of a commercial "blower". The effects on sunburn, yield, colour development and fruit maturity were determined. In contrast to the previous season, sunburn was not reduced on any of the cultivars examined. Yield parameters were not affected except in the case of 'Royal Gala' where the number of fruit was increased, and 'Cripps' Pink' where the number of fruit was reduced. Fruit colour was not affected in the apple cultivars, but chroma of 'Rosemarie' pears was reduced, indicating a less intense colour. The kaolin applications had a variable effect on fruit maturity. The effect of the foliar applications on photosynthetic photon flux density (PPFD), photosynthetic rate, stomatal conductance and transpiration rate was determined. In addition to these spot measurements, photosynthetic light response curves were determined. Measurements were taken on both the inner and outer canopies The applications significantly reduced photosynthetic rates in the inner canopy and reduced the apparent quantum efficiency of leaves on the outer canopy. No significant effect on PPFD was found. It appears that the white coating reflects light and allows less light to penetrate the leaf, thus reducing photosynthesis. Surround™ treatments could not counteract the damaging effects of the high temperatures experienced in the Western Cape during this season and was not effective as a control measure for sunburn. This does not appear to be a commercially viable solution for the sunburn problem and it would be worthwhile to investigate the use of alternative options, such as evaporative cooling.

Sonbrand is op alle kultivars verminder, alhoewel nie betekenisvolop 'Granny Smith' nie. Die effek van kaolien op oesparameters was rue konsekwent nie. kleurontwikkeling op 'Fuji' benadeel, heel moontlik Die toedienings het as gevolg van die toedieningstegniek. Met verbeterde toedieningsmetodes die volgende seisoen, is kleurontwikkeling van 'Fuji' nie benadeel nie. Tydens die tweede seisoen is die effek van kaolien op nog appelkultivars en 'Rosemarie' pere ge-evalueer. Die appelproewe is in Elgin uitgevoer, terwyl die 'Rosemarie'-proefin die Koue Bokkeveld uitgelê is. Surround™ (95% kaolien) is met kommersiële spuitpompe toegedien. Weereens is die effek van die produk op sonbrand, oesgrootte, vruggrootte, kleurontwikkeling en vrugrypheid bepaal. Sonbrand is nie verminder nie. Vruglading tydens oes is nie betekenisvol beïnvloed nie, behalwe in die geval van 'Royal Gala' waar die vruglading verhoog is, en 'Cripps' Pink' waar daar minder vrugte op die gespuite bome was. Die Surround™ toedienings het geen uitwerking op kleur van appels gehad nie, maar het die chromawaarde van 'Rosemarie' pere verlaag, d.w.s die vrugkleur was minder intens. Die kaolienspuite het 'n uiteenlopende effek op vrugrypheid gehad. Fotosintetiese foton vloeddigtheid (FFV), fotosintesetempo, huidmondjieweerstand en transpirasietempo is gemeet en ligreponskurwes van beide die buitenste en binneste blaardak is bepaal. Die Surround™ toedienings het fotosintese van blare ill die binneste gedeelte van die blaardak verminder en die kwantumdoeltreffendheid van blare op die buitenste deel van die blaardak verminder. Geen betekenisvolle effek is op FFV gekry nie. Dit wil voorkom asof die wit laag kaolien op die bome lig weerkaats en veroorsaak dat minder lig na die blaar deurdring. Dit verminder dan die fotsintesetempo. Met die baie warm weer wat in die Wes-Kaap gedurende die tweede seisoen ervaar is, kon die SUITound™behandelings nie sonbrand verhoed nie. Dit wil voorkom asof Surround™ nie 'n baie doeltreffende oplossing in kommersiële boorde sal wees nie. Alternatiewe oplossings, soos byvoorbeeld evaporatiewe verkoeling, saloorweeg moet word.

Abstract:
ZSM-5 is an aluminosilicate zeolite with high Si/Al ratio with suitable properties for catalysis, ion exchange, adsorption and membrane applications. The main goal of this thesis was to study the growth of ZSM-5 zeolite crystals from inexpensive natural sources of silica and alumina, as well as n-butylamine (NBA) as a low-cost structure directing agent. The first objective of this work was to develop pathways to synthesize ZSM-5 crystals from kaolin clay or diatomaceous earth, two inexpensive natural sources of silica and alumina (Paper I). In the case of kaolin, a heat treatment was used in order to form amorphous metakaolinite. Subsequently, dealumination of the raw materials by acid leaching made it possible to reach appropriate Si/Al ratios and to reduce the amount of impurities. Finally, leached metakaolinite or diatomaceous earth was reacted with sodium hydroxide and NBA. After synthesis optimization, both sources of aluminosilicates were found to behave differently during the course of synthesis and to lead to slightly different reaction products. The final products exhibited Si/Al ratios in the range 10-20. The use of leached diatomaceous earth allowed to reach higher yield of ZSM-5 crystals within comparable synthesis times. However, low amounts of mordenite were inevitably formed as a by-product, which was related to the high calcium content of diatomaceous earth. Therefore, the rest of the thesis focused on the kaolin system. In order to study the growth mechanism of ZSM-5 from leached metakaolinite, a proper methodology to gain local compositional data by energy dispersive spectroscopy (EDS) on aluminosilicates was developed (Paper II). Zeolite A was used as a model system that could be ion-exchanged with various elements. In order to evaluate the reliability of the measurements, inductively coupled plasma-sector field mass spectrometry (ICP-SFMS) and EDS were compared. The EDS method developed in this work resulted in molar ratios very close to theoretical values and was therefore found more reliable than ICP-SFMS. Therefore, the method developed for zeolite A was applied in the rest of the thesis work to study the formation and growth of ZSM-5 crystals. The second part of this work focused on the kaolin system in order to understand the nucleation and growth processes of the ZSM-5 crystals. This system was heterogeneous, due to the formation of a gel upon heating of the synthesis mixture. First, the internal structure of the gel was investigated (Paper III). Second, a kinetic study was performed and compared with microstructural observations (Paper IV). Finally, the mechanisms leading to Al-zoning and dendritical growth of the zeolite crystals were investigated (Paper V). The characterization of the intermediate phases during the different stages of the hydrothermal synthesis were analyzed by different analytical techniques, such as inductively coupled plasma-sector field mass spectrometry (ICP-SFMS), dynamic light scattering (DLS), extreme high resolution-scanning electron microscopy (XHR-SEM), energy dispersive spectroscopy (EDS), high resolution-transmission electron microscopy (HR-TEM), X-ray diffraction (XRD) and nitrogen gas adsorption. These investigations led to several important conclusions: 1) The walls of the gel were shown for the first time to be inhomogeneous and to possess a biphasic internal structure consisting of a mesoporous skeleton of aluminosilicate nanoparticles embedded in a silicate-rich soluble matrix of soft matter. 2) The kinetic study and microstructural evidences indicated that the early crystals were fully embedded inside the gel phase and that crystal growth was retarded, as the formation of the gel occurred simultaneously with the early growth of the crystals. Hence, nucleation and growth appeared to be solution mediated.  3) Finally, the Al zoning of the crystals was related to the biphasic internal structure of the gel, since the silicate-rich matrix was preferentially consumed first. 4) The dendrites present at the surface of the crystals during most of the growth process were shown to be caused by the presence of a web of nanoparticles, most likely originating from the mesoporous skeleton inside the gel. In the future, these findings are expected to lead to optimized synthesis pathways of catalysts with homogeneous properties and to contribute to the development of poor regions in Bolivia.

Abstract:
Abstract Fabrication of three-dimensional cavities containing kaolin pastes to be used as direct plated copper (3DPC) substrates ceramics is a very important advancement for electronic packaging of hermetic and ultraviolet light emitting diodes. This work demonstrates usage of pastes consisting of 32–40 wt% of kaolin clay and polyacrylic acid for direct ink printing (DIP) of 3DPC. Rheological and zeta potential tests were performed to determine printability and stability, respectively, of these kaolin pastes. Kaolin content variation had minimum effect on absolute values of the zeta potentials. All pastes had enough stability with the absolute values larger than 30 mV. 40 wt% kaolin solids mass paste was the optimal for DIP due to its excellent shear thinning and viscoelastic properties. Cured 40 wt% kaolin solids mass paste had superior compressive, flexural and bonding strengths. DIP using pastes containing 40 wt% of kaolin is promising for electronic chip integrated hermetic packaging.

Abstract:
An immunoblotting technique with a commercially available, polyclonal Factor XI antibody was developed for Factor XI in plasma samples.Aliquots containing equivalents of 6 ul plasma were treated with appropriate amounts of SDS, electrophoresed on 7.5 % SDS-PAGE and immunoblotted onto nitrocellulose membranes. The blots were quenched with low fat milk and incubated with 2 % Factor Xl-antiserum, which was preadsorbed with Factor XI deficient plasma. The bound Factor XI antibody was identified by incubation with 125I-labelled Factor XI followed by autoradiography. Using this method, the interaction of Factor XI with kaolin was studied in plasma. Normal plasma was incubated with kaolin for various time periods. Aliquots were removed, centrifuged and the plasma supernatant and the kaolin pellets were examined after treatment with SDS on 7.5 % SDS-PAGE followed by immunoblotting.Factor XI was adsorbed onto kaolin and, after five minutes no Factor XI antigen was present in the plasma supernatant.However, after twenty minutes a band corresponding to Factor XI became again visible in the plasma, indicating a release of Factor XI from the kaolin surface. The electrophoretic results obtained with the SDS-eluates of the kaolin pellets confirm these observations. After thirty seconds a significant amount of Factor XI was present on the kaolin, and it exhibited the same electrophoretic mobility as Factor XI in the starting material. After ten minutes incubation, the protein concentration adsorbed onto the kaolin had increased. However, after twenty minutes clearly less Factor XI was present on the kaolin than after ten minutes.Thus, our results indicate that Factor XI is quickly adsorbed from plasma onto kaolin. However, Factor XI or XIa do not remain surface-bound but are released into solution.

Full text
Abstract:
Alkali metals present in biomass fuels may cause increased bed agglomeration during fluidized bed combustion. In worst case this may lead to complete defluidization of the bed. Other problems caused by alkali metals include increased fouling and slagging. One possibility to reduce the impact of alkali metals is to add sorbents, e.g. aluminosilicates, to the bed for the capture of alkali metals. In the current investigation, the capture of vapor phase potassium compounds by kaolin was investigated in a fixed bed reactor. The reactor consisted of an alkali metal source placed at a variable temperature from which gaseous potassium compounds were generated, a fixed bed holding the kaolin, and an on-line detector for the alkali metal concentration. The on-line alkali metal detector was based on ionization of alkali metals on hot surfaces and is capable of detecting alkali metals down to ppb levels. This makes it possible to perform experiments at alkali metal concentrations relevant to fluidized bed combustion of biomass fuels. In the experiments, KCl was used as the alkali metal source with inlet concentrations of 0.5–3.5 ppm. The experiments were performed at reactor temperatures of 800–900°C and a contact time of 0.26 s. The capture efficiencies of KCl were always above 97%. The capture efficiency was somewhat higher in oxidizing than in reducing gas atmospheres. In the oxidizing gas atmosphere, the conversion was slightly higher with H2O addition than without. The capture efficiency decreased slightly as temperature or KCl concentration was increased.

Full text
Abstract:
Direct heat cogeneration using gas turbines presents an unusually attractive means of supplying two end products when both are required simultaneously. Most cogeneration applications involve steam as the thermal end product. While steam has many industrial and commercial uses, the conversion of thermal output to usable steam involves losses in the heat recovery steam generator (HRSG). When the heat rejected by a gas turbine can be used directly, system losses can be minimized. One such application exists in the kaolin industry. Kaolin is a white alumina-silicate clay used in many products, including paper, medicines, plastics and paints. One step in producing kaolin requires large spray dryers, the heat for which can be supplemented by cogeneration. This study outlines conditions necessary to achieve economic viability with cogeneration and suggests ways to maximize economic benefits. Risks associated with cogeneration ventures are also discussed.

Full text
Abstract:
Cationic polypeptide proteins found in the seeds of the tropical plant Moringa oleifera have coagulation efficiencies similar to aluminum and ferric sulfates without their recalcitrant nature. Although these proteins possess great potential to augment or replace traditional coagulants in water treatment, harvesting active protein from seeds is laborious and not cost-effective. Here, we describe an alternative method to express and secrete active M. oleifera coagulant protein (MO) in Bacillus subtilis. A plasmid library containing the MO gene and 173 different types of secretory signal peptides was created and cloned into B. subtilis strain RIK1285. Fourteen of 440 clones screened were capable of secreting MO with yields ranging from 55 to 122 mg/L of growth medium. The coagulant activity of the highest MO secreting clone was evaluated when grown on Luria broth, and cell-free medium from the culture was shown to reduce turbidity in a buffered kaolin suspension by approximately 90% compared with controls without the MO gene. The clone was also capable of secreting active MO when grown on a defined synthetic wastewater supplemented with 0.5% tryptone. Cell-free medium from the strain harboring the MO gene demonstrated more than a 2-fold reduction in turbidity compared with controls. Additionally, no significant amount of MO was observed without the addition of the synthetic wastewater, suggesting that it served as a source of nutrients for the effective expression and translocation of MO into the medium.
