Повний текст джерелаUm dos maiores problemas encontrados durante o processamento e extração de petróleo é a deposição de asfaltenos, fenômeno que causa diversos prejuízos como o entupimento de poços e formação de danos na rocha reservatório. A literatura encontra-se dividida sobre a afirmação de que as resinas são capazes de diminuir a formação de agregados, devido a sua similaridade na estrutura química com os asfaltenos. Contudo, existem estudos que afirmam que as resinas não são capazes de atuarem como surfactantes e o fator que limita o tamanho do agregado seriam as interações de repulsão existentes entre os próprios asfaltenos. Em virtude dessa problemática, esse trabalho foi realizado para verificar a influência das resinas no tamanho dos agregados asfaltênicos formados. Para esse estudo, foram utilizadas 3 amostras de petróleo de diferentes origens e ºAPI, obtidas em território nacional e realizada a extração dos asfaltenos a partir da norma ASTM D6560-00. A extração de resinas ocorreu por cromatografia a partir da adaptação da norma ASTM D2549. Em seguida, foi realizado a caracterização das amostras por RMN de ¹H e ¹³C, ao qual permitiu verificar a arquitetura dos asfaltenos em questão e o teor de carbonos aromáticos, resultado que deduz a quantidade de anéis fundidos na amostra que é um fator relacionado com a estabilidade dos asfaltenos, devido a possibilidade de interações do tipo π-π stacking. Também, peor RMN de ¹H e ¹³C foi possível ter uma ideia da estrutura dos óleos e resinas. A verificação da influência das resinas no tamanho dos agregados ocorreu por meio da técnica DOSY, com experimentos realizados em tolueno deuterado em uma concentração de 5 % (m/m) de asfaltenos, adicionando 5 mg de resinas por três vezes, obtendo as massas de 5, 10 e 15 mg de resinas na solução contendo asfaltenos. Com os valores de difusão relativa medidos no experimento foi possível verificar que a amostra de menor ºAPI possuia um maior caráter aromático nos asfaltenos, mostrando agregados de maior tamanho e mais estáveis, tendo pouquíssima influência das resinas no tamanho dos agregados.Contudo as amostras de maior ºAPI apresentaram uma influência significativa no tamanho dos agregados a partir da adição de 10 mg de resinas, indicando a existência dessa influência no tamanho dos agregados, mas observando que para ocorrer tal influência, são necessárias as condições estruturais necessárias e compatíveis das resinas com seus respectivos asfaltenos.

Повний текст джерелаThe purpose of this research was to demonstrate the interest of Nuclear Magnetic Resonance (NMR) to deal with analytical issues in the field of health products. The studies focused on two main axes. The first one targeted adulterated dietary supplements and the studies were conducted with high-field NMR. Various mono and bidimensional experiments revealed the illegal presence in dietary supplements claimed as natural, of erectile drugs and/or their structural analogues. These active substances can induce, without the consumer's knowledge, significant risks to his health. Moreover, analyses conducted with 1H and 13C NMR, highlighted cases of adulteration of dietary supplements for exercise and athletic performance with doping substances. The second axis explored the potential of low-field NMR for drug analysis. This technique, which is less expensive and more suitable for routine analyses than high-field NMR, has proved very effective in detecting cases of falsified medicines by simple one-dimensional 1H NMR experiments. Two-dimensional diffusion experiments (DOSY: Diffusion Ordered Spectroscopy), which provide virtual separation of the constituents of a complex mixture, were developed and applied for the first time to the de-formulation of a drug

Повний текст джерелаNew energy supplies need to be developed to face the growing worldwide energy demand. Heavy oils have attracted attention since their represent an important energy reserve. The problem to deal with during their upgrading is the presence of asphaltenes, representing the heaviest and the most resistant fraction of the crude oil. It is worth getting a better understanding into the physico-chemistry of asphaltenes to develop new catalysts and new conversion processes. The manuscript describes a new application of Diffusion Ordered Spectroscopy (1H-DOSY) NMR experiment. It is evaluated as a potential tool to investigate the physico-chemistry of asphaltenes from five different origins in just one experiment. Asphaltenes were studied over a wide range of concentrations in different solvents to get a deeper insight into their aggregation behaviour. For the first time, two different aggregates were observed in the semi-dilute regime and reported in this manuscript. Average size and molecular weight are estimated from diffusion measurements at infinite dilution. Based on different results, a discussion about continental and archipelago type is also provided. Asphaltenes are expected to be a distribution of the two types of asphaltenes with a more pronounced archipelago (or continental) type depending on the origin of the sample

Повний текст джерелаNMR spectroscopy is a powerful tool that allows a direct study of mixtures in a non-invasive manner. The NMR spectra of molecular species in mixtures can be separated with diffusion-ordered spectroscopy (DOSY), a ‘virtual chromatography’ approach based on the measurement of translational diffusion coefficients. Major limitation of DOSY comes from the time-dependent diffusion dimension, which results in long experiment durations, and also from the low sensitivity of NMR. The present work aims to build an innovative tool for mixtures characterization that will be faster and more efficient for low concentrated samples. We first generalized the concept of nD spatially encoded (SPEN) DOSY experiments for the analysis of complex mixtures. As bring forward by the so-called “ultrafast NMR” (UF NMR), the use of a spatial dimension to encode diffusion can accelerate experiments by several orders of magnitude since it replaces the sequential acquisition of sub-experiments by a parallel acquisition in different slices of the sample. More advanced exploration of SPENDOSY were carried out using numerical simulations for purpose of resolution and accuracy improvement. To address sensitivity issues, we then demonstrated that SPENDOSY data can be collected for hyperpolarized substrates. This particular coupling between conventional diffusion-based method with advanced techniques such as ultrafast NMR and hyperpolarization should mark a significant progress for complex mixtures analysis especially for time-evolving processes

Повний текст джерелаGold nanoparticles (NPs) have gained great interest over the past two decades due to their unique physical and chemical properties and their promising applications in many fields such as catalysis, optoelectronics, biology and medicine. These NPs are often capped by a shell of organic ligands in order to control the nucleation and growth steps during synthesis. Moreover, these ligands can afterwards be substituted by other ones to change the properties, such as hydrophobicity, biocompatibility, solubility and chemical reactivity, of the NPs. Therefore, controlling the composition of the organic layer on the NP surface as well as a fine characterisation of the interfacial affinity is very important. Unfortunately, measuring this affinity is far from a simple task, especially when the ligands are involved in dynamic exchange processes between a free and a grafted form. NMR spectroscopy has already been used to characterize molecules grafted on NPs and especially DOSY (Diffusion Ordered Spectroscopy) NMR, provides a powerful and versatile tool, enabling one to measure diffusion coefficients and to differentiate free and bound molecules according to their mobility without need for a physical separation step5. A variety of preparation methods and four types of capping agents1,2,3,4a-b (thiols, amines, phosphines, and citrate) have been explored to prepare functionalized gold NPs. DOSY NMR has been used to quantify free and grafted molecules, to characterize the interface of NPs and particularly to investigate the exchange mechanisms of bound ligands with several other types of molecules and, as a result, to evaluate the affinity, estimated through thermodynamic parameters

The analysis of mixtures is a common place challenge in the laboratory. Conventional methods demand a previous treatment which may be time consuming. At present, Nuclear Magnetic Resonance may be employed for the analysis of mixtures by using the DOSY (diffusion ordered spectroscopy) technique, whereby the different components of a mixture are separated by their diffusion coefficients. Pitches, in general, are products which are employed as starting material for the production of a variety of carbon materials, such as anodes for the production of aluminum, graphite electrodes for the steel industry, and carbon fibers. Pitches obtained from coal tar, itself a residue in the production of coke, are the most traditionally used. However, it is a carcinogen and therefore has had its use greatly diminished. Petroleum pitches, which are produced from decanted oil, may be a safer and less expensive alternative. The decanted oil is a heavy fraction obtained from catalytic cracking of petroleum. The difficulties in controlling its processing are derived from its complex composition, which includes paraffins, aromatic and heteroaromatic compounds. The present work investigates the analysis by NMR-DOSY of a mixture of model compounds present in decanted oil. Thus, a mixture of Tetracosane, Phenanthrene, 9-Mehylanthracene, Pyrene, Carbazole, 9-metil Carbazol, Dibenzothiophene, Dibenzofuran, Hexadecane, 1-Methylnaphthalene, Thiophene, Tetrahydrofuran was analyzed by NMR with an Avance III 500 MHz NMR spectrometer equipped with a BBO probe with a gradient on z-axis, at 20?C. To help in the separation by diffusion, the following polymers were used: poly-(ethyleneglycol), poly-(vinylpyrrolidone), poly-(dimethylsiloxan), poly-(butylmethacrylate) e poly-(vinylacetate).The shift reagent Eu(fod)3 was also employed. The results from DOSY-INEPT experiments show that poly-(butylmethacrylate) is the matrix which afforded the best separation of the different components of the mixture, followed by poly-(vinylacetate), poly-(ethyleneglycol) and finally, poly-(vinylpyrrolidone), which showed satisfactory results
Um grande desafio, muitas das vezes at? comum nos laborat?rios, ? a an?lise de misturas. Os m?todos convencionais em sua maioria exigem um tratamento pr?vio das misturas, o que demanda tempo, al?m de interferir diretamente no equil?brio do sistema. Hoje em dia, a t?cnica de Resson?ncia Magn?tica Nuclear pode ser usada na an?lise de misturas medindo-se o coeficiente de difus?o dos componentes da mistura, permitindo a obten??o dos espectros de cada componente individualmente por meio de um experimento r?pido que n?o interfere na mistura em si. O experimento mais comum ? o DOSY, do ingl?s Espectroscopia de Difus?o Ordenada. Piches, em geral, s?o produtos que s?o empregados como mat?rias-primas na produ??o de uma variedade de materiais de carbono, tais como: anodos de carbono para produ??o de alum?nio, eletrodos de grafite para a ind?stria sider?rgia e fibras de carbono. Piches obtidos a partir do alcatr?o da hulha, res?duo da produ??o de coque metal?rgico, s?o os tradicionalmente mais usados, mas apresentam alto potencial carcinog?nico e tem demanda decrescente em fun??o de novas tecnologias empregadas nas coquerias. Piches de petr?leo, produzidos a partir de ?leos decantados, podem potencialmente constituir uma alternativa mais segura e com maior disponibilidade. O ?leo decantado ? uma fra??o pesada obtida nas unidades de craqueamento catal?tico fluido no refino de petr?leo, e o controle de seu processamento ? dificultado pela complexidade de sua composi??o, que inclui compostos paraf?nicos, homoarom?ticos e heteroarom?ticos. O presente trabalho se prop?em a investigar a an?lise por RMN de uma mistura de padr?es de subst?ncias representativas dos tipos de compostos presentes no ?leo decantado. Assim, foram escolhidos padr?es de Tetracosano, Fenantreno, 9-metil Antraceno, Pireno, Carbazol, 9-metil Carbazol, Dibenzotiofeno, Dibenzofurano, Hexadecano, 1-metil Naftaleno, Tiofeno, Tetrahidrofurano. Todos os experimentos foram realizados no laborat?rio de RMN do PPGQ-UFRRJ a 20?C com o espectr?metro de RMN de 500 MHz Bruker Avance III, equipado com sonda BBO, gradiente no eixo z. Para auxiliar na separa??o dos componentes da mistura foram usados o pol?mero poli-(etilenoglicol), poli-(vinilpirrolidona), poli-(dimetilsiloxano), poli-(metacrilato de butila) e poli-(acetato de vinila), al?m do reagente de deslocamento Eu(fod)3. Os resultados obtidos a partir dos experimentos de DOSY-INEPT mostraram que o pol?mero PMAB foi a matriz que mais auxiliou na separa??o dos componentes da mistura em quest?o no presente trabalho, sendo seguido pelas matrizes PAV, PEG e PVP, que tamb?m apresentaram resultados satisfat?rios

Повний текст джерелаThis thesis aims at proposing new approaches to solve the inverse problem in biophysics. Firstly, we study the DOSY NMR experiment: a new hybrid regularization approach has been proposed with a novel PALMA algorithm (http://palma.labo.igbmc.fr/). This algorithm ensures the efficient analysis of real DOSY data with a high precision for all different type. In a second time, we study the mass spectrometry application. We have proposed a new dictionary based approach dedicated to proteomic analysis using the averagine model and the constrained minimization approach associated with a sparsity inducing penalty. In order to improve the accuracy of the information, we proposed a new SPOQ method based on a new penalization, solved with a new Forward-Backward algorithm with a variable metric locally adjusted. All our algorithms benefit from sounded convergence guarantees, and have been validated experimentally on synthetics and real data

Повний текст джерелаTNuclear magnetic resonance (NMR) became an irreplaceable general-purpose spectroscopic method in various sectors of chemistry; it is useful in structural analysis as well as in quantitative analysis. The aim of the studies presented in this thesis was to assess the contribution of NMR in the field of drug analysis. Indeed, more and more generics containing the same active ingredient as the brand formulation but different excipients are now found on the market. Moreover, the sale of imitated and counterfeited drugs is becoming a real problem of public health. 19F NMR was used for the determination of two fluorinated antidepressants, fluoxetine and fluvoxamine, in pharmaceutical formulations and biological fluids. The utilization of 1H NMR DOSY allowed to show the differences between the brand formulation (Prozac®) and its generics. The quality of the pharmaceutical formulations of ciprofloxacin sold in several countries or on the Internet was then assessed by 19F, 1H and DOSY 1H NMR analyses. The active ingredient was assayed and the profile of impurities contained in these formulations was determined. A “spectral signature” of all the formulations could be got thanks to. Finally, 1H DOSY NMR was applied for a screening of the brand formulations Viagra® and Cialis®, their copies and their “natural” formulations

Heavy crude oils have attracted a growing interest from oil industries around the world. In this scenario, asphaltenes, which are molecules known for their low reactivity and high molecular weight, have received special attention in recent decades, due to the problems they cause during oil processing. In an effort to minimize these problems, researchers have increasingly looked for a better understanding of aspects such as molecular structure, stability and physicochemical properties of asphaltenes, as well as for the development of methods to prevent their unwanted precipitation. In recent decades, nuclear magnetic resonance (NMR) has been widely used as a tool for the study of petroleum and its derivatives. The analysis of 1H and 13C NMR spectra allows the direct determination of a series of structural parameters such as the fractions of aromatic carbons and of carbon atoms in alkyl chains. Diffusion-ordered NMR spectroscopy (DOSY), which is based on the results of pulsed-field gradient (PFG) experiments, is a new developed NMR technique highly useful for the elucidation of complex mixtures. This work sought to identify the differences in average molecular parameters of asphaltenes from national crudes and to correlate them with the physicochemical properties of the asphaltene and of the original crude. The aim was also to investigate and to compare the asphaltenes among themselves, using data such as diffusion coefficient, concentration of these compounds in the oil and state of aggregation. Extraction and quantification of the amount of asphaltenes were performed using ASTM D6560-00 standard and the characterization of the asphaltenes was performed using the following analytical techniques: elemental analysis, atomic absorption spectrometry, mass spectrometry, high-resolution 1H and 13C NMR and DOSY. Significant changes were observed in almost all studied parameters. To study the asphaltene aggregation behavior using DOSY, the asphaltenes were diluted in various concentrations of deuterated toluene and the DOSY spectra were correlated with their respective states of aggregation. The diffusion properties were highly dependent on the concentration and type of oil from which the asphaltene was extracted
Os petróleos pesados são de grande interesse das indústrias petroleiras ao redor do mundo. Com isso, os asfaltenos, moléculas conhecidas por sua baixa reatividade e alto peso molecular, têm recebido uma atenção especial nas ultimas décadas, devido aos problemas que causam durante o processamento do óleo. Buscando minimizar estes problemas, pesquisadores têm investido cada vez mais no conhecimento da estrutura molecular e estabilidade dos asfaltenos, no entendimento de suas propriedades físico-químicas e no desenvolvimento de metodologias que impeçam sua precipitação indesejada. Nas últimas décadas, a ressonância magnética nuclear (RMN) tem sido amplamente utilizada como ferramenta no estudo de petróleos e seus derivados. A obtenção de espectros de RMN de 1H e 13C permite a determinação direta de uma série de parâmetros estruturais, tais como a fração de carbonos aromáticos e de carbonos ligados em uma cadeia alquílica. O desenvolvimento de novas técnicas de RMN, como a espectroscopia de RMN ordenada pela difusão (DOSY), baseada na sequência de gradiente de campo pulsado (PFG), têm se mostrado excelentes ferramentas na elucidação de misturas complexas. Neste trabalho, procurou-se identificar as diferenças observadas nos parâmetros moleculares médios dos asfaltenos provenientes de petróleos nacionais, bem como correlacioná-las com as propriedades físico-químicas do próprio asfalteno e do óleo de origem. Pretende-se, ainda, investigar e comparar os asfaltenos, a partir de dados de coeficiente de difusão, concentração desses compostos no óleo e forma de agregação. A extração e quantificação do teor de asfaltenos foram realizadas utilizando-se a norma ASTM D6560-00 e a caracterização dos asfaltenos foi realizada através das técnicas analíticas de: análise elementar, espectrometria de absorção atômica, espectrometria de massas de alta resolução, RMN de 1H e 13C e, RMN DOSY. Foram observadas modificações significativas em praticamente todos os parâmetros estudados. No estudo do comportamento de agregação com a técnica RMN DOSY os asfaltenos foram diluídos em concentrações diferentes de tolueno deuterado e os espectros correlacionados com os seus respectivos estados de agregação. As propriedades de difusão se mostraram altamente dependentes da concentração e do tipo de óleo utilizado para a obtenção dos asfaltenos

Повний текст джерелаNMR is a powerfull technique we decided to extend to follow interactions in complex mixtures. First part is about polydispersity index of polymer which is an important physical parameter when working with polymers. We developed here a new method, based on PEO analysis, using diffusion experiments (DOSY) by NMR to assess the polydispersity index: J. Viéville et al. / Journal of Magnetic Resonance 212 (2011) 169–173. In a second time, we worked on peptidic nucleic acids, PNA. These chemicals molecules are designed to bind DNA or RNA for clinical studies. We studied PNA in solution, by NMR to showwhich kind of interactions they form on themselves. We found very stable complexes with high fusion temperatures. Circular dichroism measurements were helpful for fusion temperature determination and structural studies. To complete this panel, we were interested in the study of protein-ligand interaction. We developed a new way to follow them, using a grafted protein on a solid phase based on HR-MAS NMR technology: J.M.P. Viéville et al. / Journal of Pharmaceutical and Biomedical Analysis 89 (2014) 18–23
