Abstract:
The effect of Mo on the formation of C54 TiSi 2 on Si (100) substrates is studied using cross-section transmission electron microscopy. For a Ti/Mo bilayer on Si, the interfacial Mo film reacts with Ti and Si to form C40 (Mo,Ti)Si 2 at 550°C. Crystal grains of metastable C40 TiSi 2 and equilibrium C54 TiSi 2 are found in the region near the interfacial (Mo,Ti)Si 2 layer due to the template phenomenon. Increasing the temperature to 600°C leads to the growth of C54 TiSi 2 throughout the film. No C49 grains can be detected. The findings confirm that the usual sequence for the formation of C54 TiSi 2, i.e. the C49 TiSi 2 forms first followed by a phase transition to the C54 TiSi 2, is altered by the interposed Mo layer. For a Mo/Ti bilayer on Si , the surface Mo layer is found to be present sequentially in (Mo,Ti) 5 Si 3 at 550°C, C49 (Mo,Ti)Si 2 at 600°C and C54 (Mo,Ti)Si 2 at 650°C. The bulk Ti beneath forms the C54 TiSi 2 following the usual route through the C49-C54 phase transition. However, this transition is now enhanced, in comparison with the C54 TiSi 2 formation with pure Ti , by the C54 (Mo,Ti)Si 2 atop that plays the role as a template precisely as the interfacial C40 (Mo,Ti)Si 2.

Abstract:
The effects of an interposed Cu layer and a surface Cu layer on the C49–C54 TiSi2 transformation temperature were studied. For the Ti/Cu/(100)Si samples the interposed Cu layer significantly enhanced the thermal stability of C49 TiSi2. The temperature for complete C49–C54 TiSi2 transformation was raised from 710 to 735 to 750 °C with the thickness of the interposed Cu layer increasing from 0 to 1.5 to 3.5 nm, correspondingly. Cu was insoluble in C54 TiSi2. For the Cu/Ti/(100)Si samples, the surface Cu layer did not at all enhance the thermal stability of the C49 phase. In the present study, the enhanced thermal stability of C49 TiCuxSi2–x can be attributed to its reduced electron/atom ratio and larger grain size relative to those of C49 TiSi2.

Abstract:
We demonstrate that the formation temperature of the C54 TiSi2 phase from the bilayer reaction of Ti on Si is lowered by approximately 100 °C by placing an interfacial layer of Mo or W between Ti and Si. Upon annealing above 500 °C, the C49 TiSi2 phase forms first, as in the reaction of Ti directly on Si. However, the temperature range over which the C49 phase is stable is decreased by approximately 100 °C, allowing C54 TiSi2 formation below 700 °C. Patterned submicron lines (0.25−1.0 μm wide) fabricated without the Mo layer contain only the C49 TiSi2 phase after annealing to 700 °C for 30 s. With a Mo layer less than 3 nm thick between Ti and Si, however, a mixture of C49 and C54 TiSi2 was formed, resulting in a lower resistivity. The enhanced formation of the C54 TiSi2 is attributed to an increased density of nucleation sites for the C49-C54 phase transformation, arising from a finer grained precursor C49 phase.

Abstract:
Direct evidence revealing fundamental differences in sequence of phase formation during the growth of TiSi2 in the presence of an ultrathin surface or interface Mo layer is presented. Results of cross-sectional transmission electron microscopy showed that when the Mo layer was present at the interface between Ti films and Si substrates, C40 (Mo,Ti)Si2 formed at the interface, and Ti5Si3 grew on top after annealing at 550 °C. Additionally, both C54 and C40 TiSi2 were found in the close vicinity of the C40 (Mo,Ti)Si2 grains. No C49 grains were detected. Raising the annealing temperature to 600 °C led to the formation of C54 TiSi2 at the expense of Ti5Si3, and the interfacial C40 (Mo,Ti)Si2 also began to transform into C54 (Mo,Ti)Si2 at 600 °C. When the Mo was deposited on top of Ti, the silicide film was almost solely composed of C49 TiSi2 at 600 °C. However, a small amount of (Mo,Ti)5Si3 was still present in the vicinity of the sample surface. Upon annealing at 650 °C, only the C54 phase was found throughout the entire TiSi2 layer with a surface (Mo,Ti)Si2 on top of TiSi2. Hence, it was unambiguously shown that in the presence of surface versus interface Mo, different routes were taken to the formation of C54 TiSi2.

Abstract:
This work investigated effects of different processing methods on the transformation of the C49-TiSi 2 phase to the C54-TiSi 2 phase in 20nm IMP Ti/Si thin films. A multi-cycle pre-cooling treatment was added to the titanium silicidation process sequence before the rapid thermal annealing (RTA) step. Compared with the conventional process, this new processing method was found to enhance formation of the low-resistivity C54-TiSi 2 phase. The extent to which the C49 transformed to the C54 phase at 720°C was observed to increase with the number of the pre-cooling cycle. The kinetic mechanisms of the C49 to C54 phase transformation were adopted to explain the experimental results. It is considered that defects at the Si/Ti interface caused by the thermal mismatch between these two layers during the pre-cooling treatment contributed to the increase in the C49 nucleation sites. This supplied more C49 grain boundaries and triple junction sites at which the C54 phase could nucleate. This discovery has a potential of reducing the complexity and cost associated with forming the low-resistivity C54 phase on sub-micron structures.

Abstract:
The relative energies of the related C11b, C40, and C54 crystal structures of group IV–VII transition-metal disilicides are obtained by ab initio self-consistent band-structure calculations using the augmented-spherical-wave (ASW) method. The structural energy differences among these three structures correlate strongly with d-band filling, with C40 being stabilized relative to C54 and C11b relative to C40 as the transition-metal d-electron count increases. The C40/C11b energy difference is <0.05 eV/atom only for CrSi2 and MoSi2. Relative C11b/C40/C54 energies are similar in magnitude to those obtained in previous studies of L12/D022/D023 competition in transition-metal aluminides.1,2 Calculations of the C49/C54 energetic competition are inaccurate; the differences in atomic coordination in these two structures are probably too large for the computational method to handle accurately. The total-energy results are interpreted by a detailed analysis of the electronic density-of-states (DOS) distributions. The stable structures do not correlate as strongly with DOS effects in the vicinity of the Fermi level as in the aluminides.

Abstract:
Different types of shocks, or the treatment of one of the players in a specific network, may influence not only the future performance of themselves but also affect their network connections. It is crucial to explore the behaviour of the whole network in response to such an event. This paper focuses on the cases of endogenously formed shock. The logic used in the peer effect literature is adopted to develop the dynamic model and accounts for the endogeneity of the shock. The model allows us to predict the endogenous part of the shock and use the remaining unexpected component to estimate the effect of the shock on the changes in the performance of network connections. The identification conditions for effect are derived, and the consistent estimation procedure is proposed.

Abstract:
Exam failures of the students in a specific network may influence not only the future performance of the student but also all students from their friendship networks, affecting the overall cohort's performance. Therefore, it is crucial to understand how the whole network responses to failure. The difficulty of such analysis is incorporated in the probability of the failures being highly endogenous. In this paper, I am applying the novel identification and estimation approach to deal with such endogeneity. I am exploring the dynamic data on the students' networks in HSE, Nizhniy Novgorod. The results suggest that, on average, the exam failure of the friend have a negative effect on future performance.

Resumo: Este trabalho relata a síntese assimétrica do fragmento C29-C39 do potente imunossupressor sangliferina A. O plano sintético utiliza como etapa-chave a reação aldólica com indução 1,5-anti entre a metil cetona 7.3 e o aldeído 31.3(S). A metil cetona 7.3 foi obtida a partir da amida de Weinreb 10.3 utilizando como etapas principais, reação de Horner-Wadsworth-Emmons, epoxidação régio- e diastereosseletiva e abertura de epóxido com cuprato de alta ordem. A amida 10.3 foi obtida a partir da reação aldólica entre N-propioniloxazolidinona 12.3 e a metacroleína mediada por titânio e hidroboração diastereosseletiva. O rendimento total para obtenção do fragmento C29-C39 foi de 18% para 16 etapas.
Abstract: This work describes the stereoselective synthesis of the C29-C39 fragment of the immunosuppressant sanglifehrin A. Our strategy involved a diastereoselective boron-mediated 1,5-anti aldol reaction of methyl ketone 7.3 with chiral aldehyde 31.3(S) as the key step.j Methyl ketone 7.3 is viewed as arising from Weinreb amide 10.3. Key steps in this approach are Horner-Waddsworth-Emmons homologation, selective epoxidation and epoxide ring opening with a higher order cuprate. The Weireb amide 10.3 is available from a titanium mediated aldol reaction of N-propionyloxazolidinone 12.3 with metacrolein followed by a diastereoselective hydroboration. This approach to the C29-C39 fragment of sanglifehrin A requires 16 steps and produced the desired molecule in 18% overall yield.

Resumo: A participação do Sistema Complemento na imunopatologia da Doença de Chagas é algo já definido. Considerando-se que a Doença de Chagas pode apresentar-se de forma bastante polimórfica, o presente trabalho teve como objetivo estudar a susceptibilidade ou resistência genética conferida pelo complemento em pacientes chagásicos. Para tanto, determinamos o polimorfismo genético de C2, C3, BF, C4A e C4B numa população de 100 pacientes chagásicos, sendo 577. da "forma cardíaca" e 43"/. da "forma indeterminada". Como controles foram estudados indivíduos adultos normais, pareados com a máxima proximidade possível com a amostra dos pacientes, segundo o grupo étnico, sexo, idade e origem geográfica. A idade média dos pacientes chagásicos como um todo foi de 41 anos, sendo que os chagásicos considerados como "forma indeterminada" apresentaram uma idade média de 38 anos e os de "forma cardíaca" de 44 anos. A idade média dos pacientes que foram a óbito durante a realização do estudo (47.) foi de 38 anos. 657. dos pacientes chagásicos eram do sexo masculino, sendo que entre eles 36 (55,387.) tinham forma cardíaca e 29 (44,627.) forma indeterminada. Os pacientes restantes (357.) eram do sexo feminino e entre eles 21 (607.) tinham forma cardíaca e 14 (407.) forma indeterminada. Considerando o grupo étnico, 57. dos pacientes chagásicos eram brancos europeus, 497. brancos brasileiros, 447. mulatos e 27. negros. Dos pacientes com forma cardíaca 48 (83,227.) eram do Norte do Paraná e 34 (79,06%) com forma indeterminada tinham a mesma procedência. 0 tempo médio entre a possível época de infecção com o T.cruzi e a realização do estudo foi de 36 anos nos chagásicos forma cardíaca e de 30 anos nos chagásicos forma indeterminada. A idade média dos controles foi de 34 anos, sendo 687. do sexo masculino e 327. do sexo feminino, rnnc í ricratiiin r" grMpn itni rn, ripe rnntrnlaq prgm branco"* europeus, 497. brancos brasileiros, 447. mulatos e 27. negros. Todos os controles eram do Paraná. As variantes polimórficas de BF, C3 e C4 foram detectadas através de eletroforese em gel de agarose, sob alta voltagem e refrigeração contínua. BF e C4 foram visualizados após imunofixação. Na determinação das variantes de C2 foi empregado o método de focalização isoelétrica em gel de po1iacri1amida, seguida de teste hemolítico. Os resultados demonstraram uma associação positiva do alótipo C3 F nos pacientes chagásicos com forma cardíaca quando comparados com os controles (p = 0,0494) e pacientes com forma indeterminada (p = 0,008). Após correção para o número de alelos testados a associação positiva de C3 F persiste apenas quando os pacientes chagásicos forma cardíaca foram comparados com os de forma indeterminada (pc = 0,016), o que sugere este alelo como marcador de susceptibilidade para a evolução de forma cardíaca da Doença de Chagas. O alótipo BF S apresentou uma associação negativa com os pacientes chagásicos de forma cardíaca (p = 0,0143) e com o grupo de Chagas total (p = 0,0233), quando comparados com os controles. Considerando a correção para o número de alelos testados a associação negativa de BF S persiste apenas quando os pacientes chagásicos forma cardíaca eram comparados com os controles (pc = 0,0429), o que sugere que indivíduos portadores deste alótipo apresentam uma maior resistência contra o desenvolvimento da Doença de Chagas na sua forma cardíaca de evolução. A análise da distribuição dos alelos de C2, C4A e C4B não apresentou nenhuma diferença estatisticamente significante entre os diferentes grupos estudados o que corrobora a importância da via alternativa do complemento nos mecanismos de defesa contra o T.cruzi. üs resultados obtidos sugerem um papel imunogenético da via alternativa do complemento na Doença de Chagas, influenciando a forma clínica de evolução dos pacientes chagásicos.

Resumo: Introdução: A compatibilidade HLA entre receptor e doador é insuficiente para evitar complicações como a doença do enxerto-contra-hospedeiro (DECH) após o transplante de células-tronco hematopoiéticas (TCTH), e isto sugere que a variabilidade não HLA pode influenciar desfechos deste procedimento terapêutico. A região de classe III do MHC abriga genes relacionados à resposta imune e aos processos inflamatórios cujas variantes alélicas têm sido associadas a doenças autoimunes e a algumas complicações pós-TCTH como a DECH. Objetivo: Este estudo retrospectivo investigou se incompatibilidades em 23 polimorfismos de único nucleotídeo (SNPs) nos genes C4A e C4B do MHC classe III estariam associados à maior incidência da DECH aguda (DECHa), crônica (DECHc) e mortalidade pós-TCTH não-aparentado. Casuística: 238 receptores(R), com idade entre 4 meses e 74 anos, 59% do sexo masculino, 52% com doenças malignas, transplantados entre 1996 e 2015, com células-tronco de medula óssea (83%) ou de sangue periférico (17%) obtidas de doadores(D) HLA-A, -B, -C, -DRB1, -DQB1 compatíveis, 61% com condicionamento mieloablativo, 90% receberam imunoprofilaxia com ciclosporina e metotrexato. Métodos: A tipagem dos 23 SNPs dos genes C4A e C4B foi realizada por amplificação alelo-específica (PCR-SSP) em 129 pares R-D e por sequenciamento de segunda geração em 109 pares R-D. Também avaliou-se o polimorfismo de HLA-DPB1 por sequenciamento de Sanger, uma vez que poderia haver associação de incompatibilidades não permissíveis deste gene com a DECH e ou mortalidade. Resultados: Dentre os pares R-D, 42,9% apresentaram 1-7 SNPs incompatíveis, cuja presença não foi associada com DECHa (RRS 0,99; p=0,948), DECHc (RRS 1,36; p=0,250) e mortalidade (RR 0,92; p=0,714). Somente 12 SNPs foram incompatíveis em 10 ou mais pares e puderam ter seu efeito isolado investigado, mas nenhum deles mostrou-se associado com DECH ou mortalidade. Na amostra total, 85,3% dos pares R-D apresentaram incompatibilidades DPB1, 41,6% permissíveis e 43,7% não permissíveis, mas sem associação com DECHa, DECHc ou mortalidade. Mesmo assim, estratificou-se os pares R-D conforme a compatibilidade DPB1: o grupo I incluiu pares R-D compatíveis e aqueles com incompatibilidades permissíveis, e o grupo II foi constituído somente de pares com incompatibilidades não permissíveis. Não houve associações entre incompatibilidades C4 e DECHa (RRS 1,03; p=0,922), DECHc (RRS 1,59; p=0,168) ou mortalidade (RR 1,21; p=0,544) no grupo I, e tampouco com respeito à DECHa (RRS 0,94; p=0,860), DECHc (RRS 1,08; p=0,855) ou mortalidade (RR 0,68; p=0,260) no grupo II . Conclusão: Apesar da identificação de incompatibilidades nos SNPs C4A e C4B entre R-D, esta característica não se mostrou fator de risco das formas aguda ou crônica da DECH e nem do aumento da mortalidade nos pacientes desta casuística. A ausência de associação pode ser devido ao pequeno tamanho amostral. Por outro lado, a diversidade nos genes C4A e C4B pode não influir na resposta imunológica da DECH.

Abstract: Introduction: Patient and donor HLA matching is not enough to avoid post-hematopoietic stem cell transplant (HSCT) complications such as graft-versus-host disease (GVHD), and this suggests that non-HLA diversity can also impacts transplant outcomes. MHC class III region hosts genes related to immune/inflammatory responses whose allelic variants have been associated to autoimmune diseases and some post-HSCT complications such as GVHD. Objective: This retrospective study investigated whether incompatibilities in one or more of 23 single-nucleotide-polymorphisms (SNPs) in the C4A and C4B genes (MHC class III) would be associated with higher incidence of GVHD and mortality post-unrelated HSCT. Casuistic: 238 recipients(R), age ranging from 4m to 74y, 59% male, 52% with malignant diseases, transplanted between 1996 and 2015 with hematopoietic stem cells from bone marrow (83%) or peripheral blood (17%) collected from HLA-A, -B, -C, -DRB1, -DQB1 matched donors (D), 61% underwent myeloablative conditioning and 90% received cyclosporine plus methotrexate as immunoprophylaxis. Methods: Typing of the 23 SNPs was done by allele-specific amplification (PCR-SSP) in 129 R-D pairs, and by next-generation sequencing in the remaining 109 R-D pairs. HLA-DPB1 polymorphism was also investigated by Sanger sequencing, once there could be associations between non-permissive mismatches on this gene and GVHD or mortality. Results: 42.9% R-D pairs had 1 to 7 C4 SNPs mismatched, but the presence of these mismatches was not associated with aGVHD (SHR 0.99; p = 0.948), cGVHD (SHR 1.36; P = 0.250) or mortality (HR 0.92; p = 0.714). Only 12 SNPs were mismatched in 10 or more R-D pairs and could have their isolated impact investigated, but none of them showed an association with GVHD or mortality. In the total sample, 85.3% R-D pairs showed DPB1 mismatches, 41.6% were permissibile and 43.7% non-permissible, but no association with aGVDH, cGVHD and mortality was found. Despite of the lack of association, R-D pairs were stratified according to DPB1 compatibility status: group I included matched pairs as well as those with permissive mismatches; and group II hosted only non-permissible mismatches. No association between C4A and C4B SNPs mismatches and aGVHD (SHR 1.03; p=0.922), cGVHD (SHR 1.59; p=0.168) or mortality (HR 1.21; p=0.544) was found in group I, and neither with aGVHD (SHR 0.94; p=0.860), cGVHD (SHR 1.08; p=0.855) or mortality (HR 0.68; p=0.260) in group II. Conclusion: Despite of the identification of C4 mismatches between R/D, this characteristic was not shown to be a risk factor for acute or chronic GVHD nor for the increase in mortality in this series of patients. The absence of associations may be due to the small sample size. On the other hand, the C4A and C4B genes diversity may not influence the immune response of the GVHD. Key words: Single nucleotide polymorphisms (SNPs). C4A and C4B genes. MHC Class III. Unrelated donor. Hematopoietic stem cell transplantation.

Abstract:
Field experiments were conducted at four sites in 2005 in the Yuma Valley, AZ (approximately 150 ft. elevation) to evaluate the performance of CN9 fertilizer [a N-calcium (Ca) based fertilizer (9-0-0-11)] in comparison to a conventional N fertilizer source with irrigated melons/cantaloupes (Cucumis melo L.). Each field was divided into two equal (approximately 40 acres) sections. One section received the grower’s N fertilizer source (Conventional) while the other section received the CN9 fertilizer. Basic plant growth and development measurements, aboveground biomass, total and marketable yield, Sugar fruit content as well as total nutrient analysis were among the main variables analyzed. In general, all phenology variables responded similarly between conventional and CN9 treatments. Fresh weight yields ranging from 4,000 to 10,000 kg/ha were observed between conventional and CN9 treatments. Statistical analyses show that total yield between conventional and CN9 was statistically the same; with the exception of the Perriconi site. Similar results were observed for marketable yield. Brix values ranged from 10 to 14 percent, statistical differences for Brix values between the conventional and CN9 treatments were found on the Perriconi and Mason 80 sites where the conventional treatment had higher sugar content in the fruit. Overall, there were no differences in nutrient uptake and allocation patterns due to the addition of CN9 among experimental sites or sampling dates. Regarding the allocation of nutrients in the rind and flesh of melons, the same patterns between treatments at all sites were observed.

Abstract:
Neste trabalho foram desenvolvidas tecnologias e novos processos de fabricação de microdispositivos analíticos visando o acoplamento desta plataforma microfluídica com a detecção condutométrica sem contato (C4D). Uma segunda etapa do trabalho concentrou esforços em melhorar os níveis de detectabilidade da C4D. Para tanto foi proposto um processo rápido e robusto para selagem de canais de vidro para produção de microdispositivos analíticos para eletroforese. Os canais de vidro foram fabricados por processo fotolitográfico e corrosão química em via úmida. Os microcanais obtidos foram selados contra outra lâmina de vidro previamente recoberta por uma membrana polimérica (PDMS) de 50 µm de espessura. Esta mesma membrana, além de promover a junção das placas de vidro, promoveu também o isolamento elétrico entre a solução no interior do canal microfluídico (de uma lâmina de vidro) e os eletrodos metálicos presentes no substrato de vidro oposto. Assim, foi possível acoplar a detecção condutométrica sem contato (C4D) com a plataforma eletroforética proposta. O desempenho analítico desta foi avaliado usando detecção por fluorescência induzida a laser (LIF) e C4D. Eficiência de aproximadamente 47000 pratos/m foi alcançada com boa repetibilidade chip-a-chip. Fluxo eletrosmótico (EOF) estável foi observado apesar da presença do material polimérico compondo parte da parede interna do canal. Com a metodologia proposta, um chip pode ser fabricado em menos de 120 min, já incluindo as etapas de gravação por fotolitografia, corrosão e selagem. Quando comparada à selagem térmica, além do ganho de tempo e facilidade no manuseio dos substratos, o método proposto não necessita de altas temperaturas e os dispositivos obtidos apresentam repetibilidade satisfatória para análises em diferentes dias e em diferentes microchips. A plataforma analítica desenvolvida foi utilizada em um estudo cinético no qual foi possível determinar os parâmetros cinéticos (Vmax = 12,64 mmol L-1 min-1 e KM = 23,8 mmol L-1) da reação de decomposição de ureia catalisada pela enzima urease. Na segunda etapa do trabalho, foi proposta a alteração de um parâmetro físico, a constante dielétrica, da membrana de PDMS usada como isolante de modo a obter um acoplamento capacitivo mais eficiente e como conseqüência uma melhor resposta no detector. Uma discussão teórica fez-se necessária a respeito do princípio de funcionamento da C4D. Os resultados obtidos com experimentos, nos quais a membrana de PDMS foi dopada com dióxido de titânio (TiO2), mostraram que a discussão sobre o funcionamento deste detector está de acordo com as considerações teóricas apresentadas neste trabalho, onde o sinal analítico é proporcional à capacitância e esta é proporcional à constante dielétrica na cela de detecção. Com esta alternativa foi possível reduzir os limites de detecção em experimentos de análise em fluxo de 385,5 para 14,7 µmol L-1 após adição de 50% em massa de TiO2 na membrana de PDMS.
In this thesis were presented technologies developed aiming new manufacturing processes for analytical microdevices by coupling of this microfluidic platform with capacitively coupled contactless conductivity detection (C4D). In a second stage of the work, we focused on improving the levels of detectability of C4D. We proposed a fast and robust process for sealing glass channels to produce analytical microdevices for electrophoresis. The glass channels were fabricated by photolithographic process and chemical wet etching. The obtained microchannels were sealed against another glass plate, which was previously coated with a 50-µm-thick membrane of poly(dimethylsiloxane) (PDMS). The purpose of this membrane, besides promoting the bonding of the two glass plates, was to act as an electrical insulator between the solution within the microfluidic channel on the top glass plate and the metal electrode present on the bottom glass chip. Thus it was possible to couple the contactless conductivity detection (C4D) with the electrophoretic platform proposed. The analytical performance was evaluated using both laser induced fluorescence (LIF) detection and C4D. Efficiency of about 47,000 plates/m was achieved with good chip-to-chip repeatability. Electroosmotic flow (EOF) was observed and stable despite the presence of polymer composing part of the inner wall of the channel. With the proposed methodology, a chip can be manufactured at less than 120 min, including the patterning step by photolithography, chemical etching, and sealing (bonding) step. When compared to the heat sealing procedure, in addition to time savings, and ease of handling of the substrates, the method does not require high temperatures, and the devices obtained show satisfactory repeatability analysis on different days and different microchips. The proposed analytical platform was used in a kinetic study in which it was possible to determine the kinetic parameters (Vmax = 12.64 mmol L-1 min-1 and KM = 23.8 mmol L-1) for the decomposition of urea catalyzed by the enzyme urease. In the second part of this thesis, it was proposed to change a physical parameter, the dielectric constant of the PDMS membrane used as an insulator, to achieve a more efficient capacitive coupling and consequently a better response in the detector. A theoretical discussion was required regarding the operating principle of C4D. The results obtained from experiments in which the PDMS membrane was doped with titanium dioxide (TiO2) showed that the discussion on the functioning of this detector is in agreement with the theoretical considerations presented in this work. The analytical signal was proportional to the capacitance and this was proportional to the dielectric constant in the detection cell. With this alternative we could reduce the detection limits in flow analysis system experiments from 385.5 to 14.7 µmol L-1 after addition of 50% wt of TiO2 in the PDMS membrane.
