Chemical bath deposition (CBD) is a suitable, inexpensive, and versatile synthesis technique to fabricate different semiconductors under soft conditions. In this study, we deposited Zn(O;OH)S thin films by the CBD method to analyze the effect of the number of thin film layers on structural and optical properties of buffer layers. Thin films were characterized by X-ray diffraction (XRD) and UV-Vis transmittance measurements. Furthermore, we simulated a species distribution diagram for Zn(O;OH)S film generation during the deposition process. The optical results showed that the number of layers determined the optical transmittance of buffer layers, and that the transmittance reduced from 90% (with one layer) to 50% (with four layers) at the visible range of the electromagnetic spectrum. The structural characterization indicated that the coatings were polycrystalline (α-ZnS and β-Zn(OH)2 to four layers). Our results suggest that Zn(O;OH)S thin films could be used as buffer layers to replace CdS thin films as an optical window in thin-film solar cells.

The study on the anion effect of different Zn sources—Zn(CH3COO)2, ZnCl2, ZnI2, Zn(NO3)2and ZnSO4—on the chemical deposition of ZnS(O,OH) films revealed that the growth rate and composition of the ZnS(O,OH) layer depend on the instability constant (pK) value of the corresponding Zn-complex Zn(L)nin the chemical bath solution. In the region ofpKZn(NH3)2+>pKZn(L)nthe ZnS(O,OH) film's growth rate and ZnS concentration in films increased with the increasing pK value of the used Zn salt complex up to the pK value of theZn[NH3]2+complex and decreased in the region wherepKZn(NH3)2+<pKZn(L)n. The band gap values (around 3.6 eV in most cases) of deposited ZnS(O,OH) films did not depend on the Zn precursor's instability constant, the ZnS(O,OH) film from zinc nitrate containing bath has higher band gap energy (Eg= 3.8 eV). The maximum efficiency of CISSe and CZTSSe monograin layer solar cells was gained with ZnS(O,OH) buffer layer deposited from CBD solution containing Zn(CH3COO)2as Zn source, which provided the highest growth rate and ZnS concentration in the ZnS(O,OH) film on glass substrates.

ABSTRACTZn(S,O,OH) Chemical Bath Deposited (CBD) remains one of the most studied Cd-free buffer layer for replacing the CBD-CdS buffer layer in a Cu(In,Ga)Se2-based (CIGSe) solar cells and has already demonstrated its potential to lead to high-efficiencies. However, in order to further increase the deposition rate of the Zn(S,O,OH) layer during the CBD, the inclusion of additives can be a reasonable strategy, as long as the efficiencies of solar cells are maintained. The aim of this work is to understand the effect of the introduction of additives such as hydrogen peroxide (H2O2), H2O2+ethanolamine (C2H7NO) and H2O2+tri-sodium citrate (Na3C6H5O7) during CBD on the deposition mechanism, the growth rate and the quality of the buffer layer. It has been shown that the combined use of H2O2 and citrate in the bath formulation allows the deposition of Zn(S,O,OH) via a mix of “ion-by-ion” and “cluster-by-cluster” mechanisms that have good properties as buffer layers leading to high efficiency solar cells.

AbstractThe chemistry and crystal structure of a unique Zn-rich kupletskite: (K1.55Na0 .21Rb0.09Sr0.01)Σ1.86(Na0.82Ca0.18)Σ1.00(Mn4.72Zn1.66Na0.41Mg0.12)Σ7.00 (Ti1.85Nb0.11Hf0.03)Σ1.99(Si7.99Al0.12)Σ8.11O26 (OH)4(F0.77OH0.23)Σ1.00, from analkalin e pegmatite at Mont Saint-Hilaire, Quebec, Canada has been determined. Zn-rich kupletskite is triclinic, , a = 5.3765(4), b = 11.8893(11), c = 11.6997(10), α = 113.070(3), β = 94.775(2), γ = 103.089(3), R1 = 0.0570 for 3757 observed reflections with Fo > 4σ(Fo). From the single-crystal X-ray diffraction refinement, it is clear that Zn2+ shows a preference for the smaller, trans M(4) site (69%), yet is distributed amongst all three octahedral sites coordinated by 4 O2− and 2 OH− [M(2) 58% and M(3) 60%]. Of note is the lack of Zn in M(1), the larger and least-distorted of the four crystallographic sites, with an asymmetric anionic arrangement of 5 O2− and 1 OH−. The preference of Zn for octahedral sites coordinated by mixed ligands (O and OH) is characteristic of its behaviour in alkaline systems, in contrast to granitic systems where Zn tends to favour [4]-coordinated, OH− and H2O-free sites with only one ligand species (O, S, Cl, B, I). In alkaline systems, [4]Zn is only present in early sphalerite or in late-stage zeolite-like minerals. The bulk of Zn in alkaline systems is present as discrete [6]Zn phases such as members of the astrophyllite, labuntsovite, milarite and nordite groups, a result of the formation of network-forming complexes inthe low-temperature, low-fS2, high-alkalinity and highly oxidizing systems.

Two novel polymers exhibiting metal–organic frameworks (MOFs) have been synthesized by the combination of a metal ion with a benzene-1,3,5-tricarboxylate ligand (BTC) and 1,10-phenanthroline (phen) under hydrothermal conditions. The first compound, poly[[(μ4-benzene-1,3,5-tricarboxylato-κ4 O:O′:O′′:O′′′)(μ-hydroxido-κ2 O:O)bis(1,10-phenanthroline-κ2 N,N′)dizinc(II)] 0.32-hydrate], {[Zn2(C9H3O6)(OH)(C12H8N2)2]·0.32H2O} n , denoted Zn–MOF, forms a two-dimensional network in which a binuclear Zn2 cluster serves as a 3-connecting node; the BTC trianion also acts as a 3-connecting centre. The overall topology is that of a 63 net. The phen ligands serve as appendages to the network and interdigitate with phen ligands belonging to adjacent parallel sheets. The second compound, poly[[(μ6-benzene-1,3,5-tricarboxylato-κ7 O 1,O 1′:O 1:O 3:O 3′:O 5:O 5′)(μ3-hydroxido-κ2 O:O:O)(1,10-phenanthroline-κ2 N,N′)dimanganese(II)] 1.26-hydrate], {[Mn2(C9H3O6)(OH)(C12H8N2)]·1.26H2O} n , denoted Mn–MOF, exists as a three-dimensional network in which an Mn4 cluster serves as a 6-connecting unit, while the BTC trianion again plays the role of a 3-connecting centre. The overall topology is that of the rutile net. Phen ligands act as appendages to the network and form the `S-shaped' packing mode.

Were synthesized different ferrites NixZn1-xFe2O4 (0,4 ≤ x ≤ 0,6) compositions by using citrate precursor method. Initially, the precursors citrates of iron, nickel and zinc were mixed and homogenized. The stoichiometric compositions were calcined at 350?C without atmosphere control and the calcined powders were pressed in pellets and toroids. The pressed material was sintered from 1100? up to 1200?C in argon atmosphere. The calcined powders were characterized by XRD, TGA/DTG, FTIR, SEM and vibrating sample magnetometer (VSM). All sintered samples were characterized using XRD, SEM, VSM and measurements of magnetic permeability and loss factor were obtained. It was formed pure ferromagnetic phase at all used temperatures. The Rietveld analyses allowed to calculate the cations level occupation and the crystallite size. The analyses obtained nanometric crystals (12-20 nm) to the calcined powder. By SEM, the sintered samples shows grains sizes from 1 to 10 μm. Sintered densities (ρ) were measured by the Archimedes method and with increasing Zn content, the bulk density decrease. The better magnetization results (105-110 emu/g) were obtained for x=0,6 at all sintering temperatures. The hysteresis shows characteristics of soft magnetic material. Two magnetization processes were considered, superparamagnetism at low temperature and the magnetic domains formation at high temperatures. The sintered toroids presents relative magnetic permeability (μr) from 7 to 32 and loss factor (tanδ) of about 1. The frequency response of toroids range from 0,3 kHz to 0,2 GHz. The composition x=0,5 presents both greater μr and tanδ values and x=0,6 the most broad range of frequency response. Various microstructural factors show influence on the behavior of μr and tanδ, such as: grain size, porosity across grain boundary and inside the grain, grain boundary content and domain walls movement during the process of magnetization at high frequency studies (0,3kKz 0,2 GHz)
Foram sintetizadas diferentes composi??es da ferrita Ni1-xZnxFe2O4 com 0,4 ≤ x ≤ 0,6 pelo uso do m?todo dos citratos precursores. Para se obter a fase estequiom?trica do sistema Ni1-xZnxFe2O4 foram misturados e homogeneizados os citratos precursores de ferro, n?quel e zinco. As composi??es estequiom?tricas foram calcinadas em atmosfera ambiente na temperatura de 350?C e depois prensadas em pastilhas e tor?ides. As amostras prensadas foram sinterizadas nas temperaturas de 1100?, 1150? e 1200?C em atmosfera de arg?nio. Os p?s calcinados foram caracterizados por DRX, TGA/DTG, FTIR, MEV e magnetometria de amostra vibrante (MAV) e as amostras sinterizadas por DRX, MEV, MAV, massa espec?fica e medidas de permeabilidade e perdas magn?ticas. Observou-se a forma??o de fase pura ferrimagn?tica em todas as temperaturas aplicadas. A an?lise pelo m?todo de Rietveld calculou o n?vel de ocupa??o dos c?tions e o tamanho de cristalito. Foram obtidos tamanhos de cristais nanom?tricos, de 12 a 20 nm para os p?s calcinados. Por MEV, as amostras sinterizadas apresentam tamanhos de gr?os na faixa de 1 a 10 μm. A massa espec?fica (ρ) do material sinterizado apresenta uma tend?ncia de diminui??o com a adi??o de Zn. Os melhores resultados de magnetiza??o foram obtidos para x=0,6 nas tr?s temperaturas de sinteriza??o, variando de 105 a 110 emu/g. As histereses mostram um perfil de materiais magn?ticos moles. Dois processos de magnetiza??o foram considerados, o superparamagnetismo a baixa temperatura (350?C) e a forma??o de dom?nios magn?ticos em altas temperaturas. Os materiais sinterizados apresentam permeabilidade (μ) de algumas unidades, de 7 a 30, e perdas magn?ticas (tanδ) por volta de 1. A resposta em freq??ncia dos n?cleos toroidais est? na faixa de 0,3 kHz a 0,2 GHz. Os maiores valores de μ e tanδ s?o para x=0,5 e a maior faixa de resposta em freq??ncia ? para x=0,6. V?rios fatores da microestrutura contribuem para o comportamento das grandezas μ e tanδ, tais como: os tamanhos dos gr?os, porosidade inter e intragranular, quantidade de contornos de gr?os e os aspectos da din?mica das paredes de dom?nios quando excitadas magneticamente sob alta freq??ncia

CdS is conventionally used as a buffer layer in Cu(In,Ga)Se2, CIGS, solar cells. The aim of this thesis is to substitute CdS with cadmium-free, more transparent and environmentally benign alternative buffer layers and to analyze how the material properties of alternative layers affect the solar cell performance. The alternative buffer layers have been deposited using Atomic Layer Deposition, ALD. A theoretical explanation for the success of CdS is that its conduction band, Ec, forms a small positive offset with that of CIGS. In one of the studies in this thesis the theory is tested experimentally by changing both the Ec position of the CIGS and of Zn(O,S) buffer layers through changing their gallium and sulfur contents respectively. Surprisingly, the top performing solar cells for all gallium contents have Zn(O,S) buffer layers with the same sulfur content and properties in spite of predicted unfavorable Ec offsets. An explanation is proposed based on observed non-homogenous composition in the buffer layer. This thesis also shows that the solar cell performance is strongly related to the resistivity of alternative buffer layers made of (Zn,Mg)O. A tentative explanation is that a high resistivity reduces the influence of shunt paths at the buffer layer/absorber interface. For devices in operation however, it seems beneficial to induce persistent photoconductivity, by light soaking, which can reduce the effective Ec barrier at the interface and thereby improve the fill factor of the solar cells. Zn-Sn-O is introduced as a new buffer layer in this thesis. The initial studies show that solar cells with Zn-Sn-O buffer layers have comparable performance to the CdS reference devices. While an intrinsic ZnO layer is required for a high reproducibility and performance of solar cells with CdS buffer layers it is shown in this thesis that it can be thinned if Zn(O,S) or omitted if (Zn,Mg)O buffer layers are used instead. As a result, a top conversion efficiency of 18.1 % was achieved with an (Zn,Mg)O buffer layer, a record for a cadmium and sulfur free CIGS solar cell.

The Layered Double Hydroxides has become extremely promising materials due to its range of applications, easily obtained in the laboratory and reusability after calcination, so the knowledge regarding their properties is of utmost importance. In this study were synthesized layered double hydroxides of two systems, Mg-Al and Zn-Al, and such materials were analyzed with X-ray diffraction and, from these data, we determined the volume density, planar atomic density, size crystallite, lattice parameters, interplanar spacing and interlayer space available. Such materials were also subjected to thermogravimetric analysis reasons for heating 5, 10, 20 and 25 ? C / min to determine kinetic parameters for the formation of metaphases HTD and HTB based on theoretical models Ozawa, Flynn-Wall Starink and Model Free Kinetics. In addition, the layered double hydroxides synthesized in this working ratios were calcined heating 2.5 ? C / min and 20 ? C / min, and tested for adsorption of nitrate anion in aqueous solution batch system at time intervals 5 min, 15 min, 30 min, 1h, 2h and 4h. Such calcined materials were also subjected to exposure to the atmosphere and at intervals of 1 week, 2 weeks and 1 month were analyzed by infrared spectroscopy to study the kinetics of regeneration determining structural called "memory effect"

Resumo: Neste trabalho, foi estudado a formação dos pós de hexahidroxodizincato de cálcio dihidratado, CaZn2(OH)6.2H2O (CZO) sobre condições hidrotermais-microondas (HM) e partindo de diferentes reagentes e surfactantes. Estes pós foram analisados por difração de raios X (DRX), microscopia eletrônica de varredura com canhão de elétrons por emissão de campo (FEG-MEV), espectroscopia de absorção na região do ultravioleta visível (UV-vis), espectroscopia na região do infravermelho (IV) e medidas de fotoluminescência (FL). Os padrões de DRX confirmaram que a fase CZO pura foi obtida após o processamento HM realizado a 130 ºC por 2 h com a síntese partindo de nitratos, enquanto que as demais apresentaram fases secundárias. As micrografias FEG-MEV indicaram que as modificações bem como o crescimento das micropartículas de CZO foram orientadas pelo mecanismo de coalescência e Ostwald-ripening. O espectro UV-vis ilustrou que este material tem um band gap óptico indireto. Os pós de CZO puros exibiram uma emissão amarela quando excitados por um comprimento de onda de 350 nm em temperatura ambiente, enquanto que os demais exibiram uma emissão na região do laranja
Abstract: In this work, it was studied the formation of calcium hexahydroxodizincate dehydrate, CaZn2(OH)6.2H2O (CZO) powders under microwave-hydrothermal (MH) conditions and using the different reagents and surfactants. These powders were analyzed by X-ray diffraction (XRD), Field-emission gum scanning electron microscopy (FEG-SEM), ultraviolet-visible (UV-vis) absorption spectroscopy, infra red spectroscopy (FTIR) and photoluminescence (PL) measurements. XRD patterns confirmed that the pure CZO phase was obtained after MH processing performed at 130 ºC for 2 h. FEG-SEM micrographs indicated that the morphological modifications as well as the growth of CZO microparticles are governed by Ostwal-ripening and coalescence mechanisms. UV-vis spectra showed that this material have an indirect optical band gap. The pure CZO powders exhibited an yellow PL emission when excited by 350 nm wavelength at room temperature, whereas the other powders exhibited the orange emission

Discussions about pollution caused by vehicles emission are old and have been developed along the years. The search for cleaner technologies and frequent weather alterations have been inducing industries and government organizations to impose limits much more rigorous to the contaminant content in fuels, which have an direct impact in atmospheric emissions. Nowadays, the quality of fuels, in relation to the sulfur content, is carried out through the process of hydrodesulfurization. Adsorption processes also represent an interesting alternative route to the removal of sulfur content. Both processes are simpler and operate to atmospheric temperatures and pressures. This work studies the synthesis and characterization of aluminophosphate impregnate with zinc, molybdenum or both, and its application in the sulfur removal from the gasoline through the adsorption process, using a pattern gasoline containing isooctane and thiophene. The adsorbents were characterized by x-ray diffraction, differential thermal analysis (DTG), x-ray fluorescence and scanning electron microscopy (SEM). The specific area, volume and pore diameter were determined by BET (Brunauer- Emmet-Teller) and the t-plot method. The sulfur was quantified by elementary analysis using ANTEK 9000 NS. The adsorption process was evaluated as function of the temperature variation and initial sulfur content through the adsorption isotherm and its thermodynamic parameters. The parameters of entropy (ΔS), enthalpy variation (ΔH) and free Gibbs energy (ΔG) were calculated through the graph ln(Kd) versus 1/T. Langmuir, Freundlich and Langmuir-Freundlich models were adjusted to the experimental data, and the last one had presented better results. The thermodynamic tests were accomplished in different temperatures, such as 30, 40 and 50?C, where it was concluded the adsorption process is spontaneous and exothermic. The kinetic of adsorption was studied by 24 h and it showed that the capability adsorption to the adsorbents studied respect the following order: MoZnPO > MoPO > ZnPO > AlPO. The maximum adsorption capacity was 4.91 mg/g for MoZnPO with an adsorption efficiency of 49%.
As discuss?es sobre o problema da polui??o causada por emiss?es veiculares s?o antigas e v?m evoluindo com o passar do tempo. A procura por tecnologias mais limpas e as altera??es clim?ticas cada vez mais frequentes induziram as ind?strias e os ?rg?os governamentais a impor limites cada vez mais rigorosos para os teores de contaminantes nos combust?veis, os quais impactam diretamente nas emiss?es atmosf?ricas. Atualmente a forma de melhorar a qualidade dos combust?veis, quanto ao enxofre, ? atrav?s do processo de hidrodessulfuriza??o e recentemente, os processos de adsor??o tem se mostrado como uma alternativa bastante interessante ? remo??o de enxofre, pois tais processos s?o mais simples e operam a temperaturas e press?es atmosf?ricas. O presente trabalho contempla a s?ntese e caracteriza??o do aluminofosfato impregnado com zinco, molibd?nio ou ambos e sua aplica??o no estudo da remo??o de enxofre da gasolina atrav?s do processo de adsor??o, utilizando uma gasolina modelo contendo iso-octano e tiofeno. Os adsorventes foram caracterizados por difra??o de raios-X, an?lise termogravim?trica (ATG), fluoresc?ncia de raios-X e microscopia eletr?nica de varredura (MEV). A ?rea espec?fica, volume e di?metro de poros foram determinados pelo m?todo BET (Brunauer-Emmet-Teller) e m?todo t-plot. O enxofre foi quantificado por analise elementar atrav?s do ANTEK 9000 NS. O Processo de adsor??o foi avaliado em fun??o da varia??o da temperatura e da concentra??o inicial de enxofre atrav?s das isotermas de adsor??o e de seus par?metros termodin?micos. Os par?metros varia??o de entropia (ΔS), varia??o de entalpia (ΔH) e varia??o da energia livre de Gibbs (ΔG) foram calculados pelo gr?fico de ln(K) versus 1/T. Os modelos de Langmuir, Freundlich e Langmuir-Freundlich foram ajustados aos dados experimentais, tendo o ?ltimo apresentado os melhores resultados. Os testes termodin?micos foram realizados nas temperaturas de 30, 40, 50 ?C e constatou-se que o processo de adsor??o ? espont?neo e exot?rmico. A cin?tica da adsor??o foi estudada por 24 horas e mostrou que a capacidade de adsor??o para os adsorventes estudados segue a seguinte ordem: MoZnPO > MoPO > ZnPO > AlPO. A capacidade m?xima de adsor??o foi 4,91 mg/g para o MoZnPO com uma efici?ncia de adsor??o de 49%.

Thin-film solar cells based on Cu(In,Ga)Se2 contain a thin buffer layer of CdS in their standard configuration. In order to avoid cadmium in the device for environmental reasons, Cd-free alternatives are investigated. In this thesis, ZnO-based films, containing Mg or S, grown by atomic layer deposition (ALD), are shown to be viable alternatives to CdS. The CdS is an n-type semiconductor, which together with the n-type ZnO top-contact layers form the pn-junction with the p-type Cu(In,Ga)Se2. From device modeling it is known that a buffer layer conduction band (CB) position of 0-0.4 eV above that of the Cu(In,Ga)Se2 layer is consistent with high photovoltaic performance. For the Cu(In,Ga)Se2/ZnO interface this position is measured by photoelectron spectroscopy and optical methods to –0.2 eV, resulting in increased interface recombination. By including sulfur into ZnO, a favorable CB position to Cu(In,Ga)Se2 can be obtained for appropriate sulfur contents, and device efficiencies of up to 16.4% are demonstrated in this work. From theoretical calculations and photoelectron spectroscopy measurements, the shift in the valence and conduction bands of Zn(O,S) are shown to be non-linear with respect to the sulfur content, resulting in a large band gap bowing. ALD is a suitable technique for buffer layer deposition since conformal coverage can be obtained even for very thin films and at low deposition temperatures. However, deposition of Zn(O,S) is shown to deviate from an ideal ALD process with much larger sulfur content in the films than expected from the precursor pulsing ratios and with a clear increase of sulfur towards the Cu(In,Ga)Se2 layer. For (Zn,Mg)O, single-phase ZnO-type films are obtained for Mg/(Zn+Mg) < 0.2. In this region, the band gap increases almost linearly with the Mg content resulting in an improved CB alignment at the heterojunction interface with Cu(In,Ga)Se2 and high device efficiencies of up to 14.1%.

Un des défis concernant les cellules solaires à base de Cu(In,Ga)Se2 est le remplacement de la couche tampon de CdS déposée par bain chimique (CBD) par un matériau exempt de Cd déposé sous vide. L’objectif de ce travail est d’évaluer le potentiel des couches minces de Zn(O,S) déposées par co-pulvérisation cathodique RF (PVD) en tant que couche tampon alternative. Les propriétés matériau de ces couches ont été tout d’abord comparées à une référence (CBD)Zn(O,S) dont les conditions de dépôt ont été préalablement optimisées. Pour une composition équivalente, la technique de dépôt employée semble avoir un fort impact sur les propriétés optiques et structurales des couches. Le comportement électrique des dispositifs résultants s’en trouve également affecté. Dans le cas des cellules à couche tampon (CBD)Zn(O,S), nous avons mis en évidence la nécessité de prendre en compte l’ensemble du dispositif pour comprendre les phénomènes observés. Ces progrès ainsi qu’une meilleure compréhension des propriétés des couches (CBD)Zn(O,S) nous ont permis de réaliser des dispositifs stables sous éclairement avec des rendements de 16 % (sans couche anti-reflet). Pour les cellules à couche tampon (PVD)Zn(O,S), l’ajustement du taux de soufre a permis de contrôler l’alignement de bande à la jonction absorbeur/couche tampon et de permettre l’obtention de Jsc comparables à ceux des cellules avec (CBD)Zn(O,S). Bien que la structure telle quelle de la couche tampon (PVD)Zn(O,S) pour une teneur en soufre optimale ne permette pas d’obtenir les Voc attendus, ces résultats ouvrent de nouvelles perspectives de recherche sur la compréhension des hétéro-interfaces dans les cellules solaires Cu(In,Ga)Se2
Thin film solar cell based on Cu(In,Ga)Se2 contain a thin, chemically deposited (CBD), cadmium sulfide (CdS) buffer layer. For environmental and industrial reasons, its replacement by a Cd-free material deposited under vacuum is among the challenges of the research community. In this work, co-sputtered (PVD)Zn(O,S) thin films have been studied as an alternative buffer layer. The properties of these layers have been compared to an optimized (CBD)Zn(O,S) reference. It is observed that the deposition technique has a strong impact on the optical and structural properties of the films for a given composition. As a result, the electrical behavior of the corresponding devices is also affected. The electrical characterization of (CBD)Zn(O,S)-buffered solar cells has shown that the absorber and the window layers properties strongly influence the performance of the cells. These progress together with the understanding of Zn(O,S) films properties makes it possible the realization of 16 % efficiency stable devices with a (CBD)Zn(O,S) buffer layer. Meanwhile, the tuning of the sulfur content has lead to the control of the conduction band offset in CIGSe/(PVD)Zn(O,S) devices and the achievement of similar Jsc than the one of (CBD)Zn(O,S)-buffered devices. Although the present structure of the (PVD)Zn(O,S) buffer layer is not suitable to obtain comparable Voc, these results offer many research perspectives in hetero-interface for a better understanding of Cu(In,Ga)Se2-based solar cells

The growing utilization of surfactants in several different areas of industry has led to an increase on the studies involving solutions containing this type of molecules. Due to its amphiphilic nature, its molecule presents one polar part and one nonpolar end, which easily interacts with other molecules, being able to modify the media properties. When the concentration in which its monomers are saturated, the airliquid system interface is reached, causing a decrease in interfacial tension. The surfactants from pure fatty acids containing C8, C12 and C16 carbonic chains were synthesized in an alcoholic media using sodium hydroxide. They were characterized via thermal analysis (DTA and DTG) and via infrared spectroscopy, with the intention of observing their purity. Physical and chemical properties such as superficial tension, critical micelle concentration (c.m.c), surfactant excess on surface and Gibbs free energy of micellization were determined in order to understand the behaviour of these molecules with an aqueous media. Pseudo-ternary phase diagrams were obtained aiming to limit the Windsor equilibria conditions so it could be possible to understand how the surfactants carbonic chain size contributes to the microemulsion region. Solutions with known concentrations were prepared to study how the surfactants can influence the dynamic light scattering spectroscopy (DLS) and how the diffusion coefficient is influenced when the media concentration is altered. The results showed the variation on the chain size of the studied surfactant lipophilic part allows the conception of surfactants with similar interfacial properties, but dependent on the size of the lipophilic part of the surfactant. This variation causes the surfactant to have less tendency of microemulsionate oil in water. Another observed result is that the n-alcanes molecule size promoted a decrease on the microemulsion region on the obtained phase diagrams
O crescente uso de tensoativos nas mais diferentes ?reas da ind?stria tem levado a um aumento nos estudos envolvendo solu??es contendo este tipo de mol?cula. Devido a sua natureza anfif?lica, sua mol?cula apresenta uma parte polar e outra apolar, que facilmente interage com outros tipos de mol?culas, podendo modificar as propriedades do meio. Quando a concentra??o, na qual seus mon?meros saturam, a interface do sistema ar-l?quido, ? atingida promovendo a redu??o da tens?o interfacial. Os tensoativos dos ?cidos graxos puros com cadeias carb?nicas C8, C12 e C16 foram sintetizados em meio alco?lico, utilizando hidr?xido de s?dio. Eles foram caracterizados por an?lise t?rmica (DTA e DTG) e espectroscopia de infravermelho com o objetivo de se observar a pureza dos mesmos. Foram determinadas algumas propriedades f?sicoqu?micas como: tens?o superficial, c.m.c. , excesso de tensoativo na interface e energia livre de Gibbs de miceliza??o a fim de se entender o comportamento das intera??es dessas mol?culas com meio aquoso. Foram elaborados diagramas de fase pseudotern?rios com o intuito de realizar as delimita??es do equil?brio de Winsor para compreender como o tamanho da cadeia carb?nica dos tensoativos contribui com a regi?o de microemuls?o. Preparou-se solu??es com concentra??es conhecidas para se estudar como os tensoativos podem influenciar a espectroscopia de espalhamento din?mico de luz (Dynamic Ligth Scattering - DLS) e como o coeficiente de difus?o ? influenciado quando a concentra??o do meio ? alterada. Os resultados mostraram que o aumento ou diminui??o do tamanho da cadeia da parte lipof?lica dos tensoativos estudados permite conceber tensoativos com propriedades interfaciais similares, mas tamb?m dependente do tamanho da parte lipof?lica do tensoativo. Esta varia??o deixa o tensoativo com menor tend?ncia a microemulsionar ?leo em ?gua. Outro resultado observado ? que o tamanho das mol?culas de n-alcanos promoveu uma redu??o da regi?o de microemuls?o dos diagramas de fases obtidos

Magnetic ceramics have been widely investigated, especially with respect to intrinsic and extrinsic characteristics of these materials. Among the magnetic ceramic materials of technological interest, there are the ferrites. On the other hand, the thermal treatment of ceramic materials by microwave energy has offered various advantages such as: optimization of production processes, high heat control, low consumption of time and energy among others. In this work were synthesized powders of Ni-Zn ferrite with compositions Ni1- xZnxFe2O4 (0.25 ≤ x ≤ 0.75 mols) by the polymeric precursor route in two heat treatment conditions, conventional oven and microwave energy at 500, 650, 800 and 950?C and its structural, and morphological imaging. The materials were characterized by thermal analysis (TG/ DSC), X-ray diffraction (XRD), absorption spectroscopy in the infrared (FTIR), scanning electron microscopy (SEM), X-ray spectroscopy and energy dispersive (EDS) and vibrating sample magnetometry (VSM). The results of X-ray diffraction confirmed the formation of ferrite with spinel-type cubic structure. The extrinsic characteristics of the powders obtained by microwave calcination and influence significantly the magnetic behavior of ferrites, showing particles ferrimagn?ticas characterized as soft magnetic materials (soft), is of great technological interest. The results obtained led the potential application of microwave energy for calcining powders of Ni-Zn ferrite

Por outro lado, o tratamento t?rmico de materiais cer?micos por energia de microondas tem oferecido diversas vantagens, tais como: otimiza??o dos processos de obten??o, alto controle de aquecimento, menor consumo de tempo e energia entre outras. Neste trabalho, foram sintetizados p?s de ferritas Ni-Zn com composi??es Ni1-xZnxFe2O4 (0,25 ≤ x ≤ 0,75 mols) pela rota dos precursores polim?ricos em duas condi??es de tratamento t?rmico, em forno convencional e por energia de microondas a 500, 650, 800 e 950?C, e sua caracteriza??o estrutural, morfol?gica e magn?tica. Os materiais obtidos foram caracterizados por an?lises t?rmicas (TG/DSC), difra??o de raios x (DRX), espectroscopia de absor??o na regi?o do infravermelho (FTIR), microscopia eletr?nica de varredura (MEV), espectroscopia de raios X por dispers?o de energia (EDS) e magnetometria de amostra vibrante (VSM). Os resultados da difra??o de raios X confirmaram a forma??o da ferrita com estrutura c?bica do tipo espin?lio. As caracter?sticas extr?nsecas dos p?s obtidos e a calcina??o por microondas influenciaram de forma significativa o comportamento magn?tico das ferritas, apresentando part?culas ferrimagn?ticas, caracterizadas como materiais magn?ticos moles (macias), sendo de grande interesse tecnol?gico. Os resultados obtidos induziram o potencial de aplica??o de energia de microondas para a calcina??o de p?s de ferritas Ni-Zn

Session 9 of the RAINBOW treatment protocol focuses on improving family problem-solving and coping (ingredient O: Oh, how do we solve this problem? of RAINBOW), and is conducted with the parent/caregiver(s), child, and siblings. It is important for all family members to have opportunities to talk about their experiences and to have that experience respected by the family. The therapist works with the family to improve interactions at home by problem-solving difficult situations and developing a family plan to minimize behavioral escalation once it occurs. In addition, the session aims to foster affiliation among family members through emphasizing shared experiences, positive feelings, and common goals.

The Oxygen Group of the Periodic Table consists of the elements oxygen O, sulfur S, selenium Se, tellurium Te, and polonium Po. The outer electron structure ns2np4 characterizes all five of the elements, with n representing principal quantum numbers 2, 3, 4, 5, and 6, respectively. The ns2np4 indicates the possibility of oxidation states of −II, II, IV, and VI in all of the elements, with O almost always showing a value of −II. As one descends the group, non-metallic character gradually diminishes with only Po being distinctly metallic, and the crossover occurring with the metalloid or semi-metal Te. The II and the VI oxidation states decrease in stability down the group, and the IV oxidation state increases. Oxygen stands out as considerably different from the other elements, there being numerous discontinuities in properties between it and S. Covalent radii in pm are as follows: O(73), S(102), Se(117), Te(135), and Po (149). Ionic radii in pm are as: O−2(126), S−2(170), Se−2(184), and Te−2(207). a. E–pH diagrams. Figure 10.1 depicts the E–pH diagram for O with the soluble species (except H+) at 10−1.0 M. The upper region is occupied by O2, the lower region by H2, and the intermediate area by HOH and its equilibrium species H+ and OH−. This diagram functions as the background for all chemical reactions in HOH solution and in an air or O2 atmosphere. The compound hydrogen peroxide H2O2 is another compound of O and H which is of importance. Because of complicated kinetic behavior, H2O2 can act as either an oxidant or a reductant. Figure 10.2 displays the E–pH diagram for H2O2 at 10−1.0 M when it is functioning as an oxidizing agent. Figure 10.3 is the E–pH diagram for H2O2 at 10−1.0 M when it is acting as a reducing agent. Equations for the lines that separate the species are displayed in the legends of the diagrams.

This open file reports geochemical data for stream and groundwater samples collected around the Casino porphyry Cu-Au-Mo deposit, one of the largest and highest-grade deposits of its kind in Canada. The calc-alkaline porphyry is hosted in a Late Cretaceous quartz monzonite and associated breccias in the unglaciated region of west central Yukon. Water chemistry around the deposit was investigated because: (i) the deposit has not yet been disturbed by mining; (ii) the deposit was known to have metal-rich waters in local streams; and (iii) the deposit has atypically preserved ore zones. Stream water samples were collected at 22 sites and groundwater samples were collected from eight sites. Surface and groundwaters around the Casino deposit are anomalous with respect to Cd (up to 5.4 µg/L), Co (up to 64 µg/L), Cu (up to 1657 µg/L), Mo (up to 25 µg/L), As (up to 17 µg/L), Re (up to 0.7 µg/L), and Zn (up to 354 µg/L) concentrations. The stable isotopes of O and H of the groundwaters are essentially identical to the surface waters and plot close to the local and global meteoric water lines, indicating that the waters represent modern recharge, consistent with the generally low salinities of all the waters (total dissolved solids range from 98 to 1320 mg/L). Sulfur and Sr isotopes are consistent with proximal waters interacting with the Casino rocks and mineralization; a sulfide-rich bedrock sample from the deposit has delta-34S = -1.2 permille and proximal groundwaters are only slightly heavier (-0.3 to 3.1 permille). These geochemical and isotopic results indicate that surface water geochemistry is a suitable medium for mineral exploration for porphyry-style mineralization in the Yukon, and similar unglaciated regions in Canada. The atypical geochemical signature (Mo, Se, Re, As, Cu) of these types of deposits are typically reflected in the water chemistry and S isotopes provide a more local vectoring tool.

A comprehensive study of Mississippi Valley-type base-metal deposits across the Canadian Cordillera was done to compare and contrast their features. Extensive dissolution of host rocks is followed by multiple generations of dolomite cements from early, low-temperature, fine-grained to coarser, higher temperature types that overlap with Zn-Pb sulfide minerals; late-stage calcite occludes residual porosity. Dolomite is generally chemically stoichiometric, but ore-stage types are often rich in Fe (&lt;1.3 weight per cent FeO) with small sphalerite inclusions. Sphalerite-hosted fluid inclusions record ranges for homogenization temperatures (77-214°C) and fluid salinity (1-28 weight per cent equiv. NaCl±CaCl2). These data suggest fluid mixing with no single fluid type related to all sulfide mineralization. In situ secondary ion mass spectrometry (SIMS) generated delta-18OVSMOW values for carbonate minerals (13-33 permille) reflect dolomite and calcite formation involving several fluids (seawater, basinal, meteoric) over a large temperature range at varying fluid-rock ratios. Sphalerite and pyrite SIMS delta-34SVCDT values vary (8-33 permille) but in single settings have small ranges (&lt;2-3 permille) that suggest sulfur was reduced via thermochemical sulfate reduction from homogeneous sulfur reservoirs. Collectively, the data implicate several fluids in the mineralizing process and suggest mixing of a sulfur-poor, metal-bearing fluid with a metal-poor, sulfide-bearing fluid.
