Por possuir propriedades muito similares as do ferro(III), que desempenha papel essencial para a vida humana, o gálio(III) é capaz de mimetizar esse íon em sistemas biológicos, participando assim de importantes processos celulares. O gálio(III), uma vez no organismo provoca alterações em algumas funcionalidades celulares, podendo, essas mudanças, ser positivas para o tratamento de câncer e infecções bacterianas. Contudo, atualmente o gálio(III) está apenas disponível para administração por via intravenosa, que é menos confortável ao tratamento, além de, muitas vezes apresentarem um custo maior em comparação com as cápsulas. A administração por essa via é justificada pelas limitações na biodisponibilidade do gálio(III). Entretanto, visto que sistemas poliméricos têm se mostrado promissores para melhorar a biodisponibilidade de alguns princípios ativos e são amplamente utilizados na indústria farmacêutica, esse trabalho tem como objetivo principal o desenvolvimento de um sistema polimérico constituído por quitosana e alginato de sódio visando possibilitar a administração do gálio(III) por via oral para tratamento terapêutico de algumas enfermidades, incluindo o câncer.

Os polímeros sintéticos, oriundos de materiais de origem fóssil e não biodegradável, em especial os plásticos, possuem importância em praticamente todas as áreas da vida moderna. Eles ganharam destaque por substituírem de forma eficiente, outros materiais como madeira, papel, vidro e metal. Os plásticos são populares porque são econômicos, leves, resistentes à oxidação, não são afetados fortemente pelo intemperismo, são versáteis e isolantes elétricos. O uso desses plásticos vem aumentando muito no mundo e devido a sua principal propriedade - a durabilidade - um sério problema acompanha o homem contemporâneo: a enorme quantidade de lixo produzida. Esse lixo pode levar mais de uma centena de anos para se decompor, resultando em problemas ambientais para a humanidade. Neste contexto, polímeros biodegradáveis como o amido e o poli(butileno succinato), PBS, podem ser inseridos como uma alternativa para substituir os tradicionais plásticos e diminuir assim o problema gerado pela produção de lixo e resíduos. Como alternativa a essas limitações, a associação de ambos os polímeros em blendas surge como uma possível solução. Além de diminuir o preço do produto final, uma vez que não se trabalha com o polímero sozinho, as blendas poliméricas permitem uma melhora nas propriedades mecânicas, na estabilidade do material e na diminuição do caráter hidrofílico do amido. Isso possibilita a aplicação desse material na indústria de plásticos para confecção de artigos de uso comercial e doméstico tais como canudos, pratos, talheres, embalagens, etc. Além dessa aplicabilidade, o material obtido é biodegradável e dessa forma, não agressivo ao meio ambiente.

In the various methods of analysis defined, a stage of sample preparation and extraction analytes is one that requires a lot of care and involves several steps using an expressive amount of organic solvents. In addition to being relatively time-consuming, they involve a considerable operational cost and generate a volume of waste to be treated. The development of new extraction methods that use little or no solvent is one of the most essential needs of laboratories analysis, botht for reduction of amount of waste, as well as for the reduction of the reduced time and also in the minimization of costs. The recent patent number BR1020180731670, obtained by INTECHLAB (Laboratory of Integrated Technologies of CEFET-MG) presented the development of an innovative technology for this purpose. The prototype called IT-FEX (IntraTube Flux Extraction Device), uses an internally polymeric phase coated glass tube (liner) to capture analystes present in liquid samples allowing the creation of a new prototype called HS-IT-FEX. This new prototype, which also uses an internally coated glass tube with PDMS polymer (polydimethylsiloxane), was developed to operate in headspace mode which allows the capture of volatile analytes. After trapping the analytes, these are thermally desorbed and analyzed by gas chromatography coupled with mass spectrometer as a detector. Laboratory tests with the new prototype HS-IT-FEX were carried out with solutions of PAHs (Polycyclic Aromatic Hydrocarbons), Persistent Organic Pollutants) that require attention regarding environmental monitoring. The preliminary results of this work demonstrate the possibility of trapping PAHs (such as naphthalene, acenaphtene, acenaphthylene and fluorene) from headspace generated from aqueous solutions without using organic and at low costs. Due to the lack of reproducibility of the chromatographic data in some tests, the need to improve the prototype was found, especially in the sealing system.

In recent years, molybdenum oxide catalysts have been prominent in applications involving oxidation of organic substrates with hydrogen peroxide. In this work, molybdenum oxide (NFMo) nanofibers were synthesized by simple hydrothermal treatment of bis (acetylacetonate) -dioxomolbdenum (VI) (MoO2 (acac) 2) in aqueous solution, without the need for surfactants or other growth directives. . This material was characterized and applied as a catalyst in oxidation reactions of various organic substrates in the presence of hydrogen peroxide or TBHP as oxidants. The synthesized NFMo were characterized by XRD, IR, Raman, SEM, TG, N2 Physisorption. The results confirmed the obtaining of MoO3 orthorhombic crystalline phase and allowed the observation of well defined and uniform morphology of the material. Subsequently, NFMo were applied in selective oxidation reactions of sulfur compounds such as DFS, MFS, DBT and BT, and showed excellent catalytic activity under mild reaction conditions. The catalyst also showed good oxidation efficiency of other organic substrates, such as pyridine, quinoline and 5-HMF, and was effective for olefin epoxidation in the presence of TBHP. The obtained results indicate that the studied catalyst presented great potential in selective oxidation reactions, proving very promising for applications in ODS reactions.

O presente trabalho foi desenvolvido para ampliar as possibilidades de aplicação do amido termoplástico (TPS) utilizando o método de extrusão reativa. O amido é um polissacarídeo produzido por algumas plantas para armazenar energia e é formado exclusivamente por moléculas de glicose unidas por ligações convalentes. Quando o amido é processado com glicerina, obtemos o amido termoplástico. Como objetivo principal temos a obtenção do amido termoplástico reticulado através do processo de extrusão reativa, utilizando diferentes ácidos carboxílicos, com elevada hidrofobicidaqde e propriedades mecânicas melhoradas quando comparado ao amido termoplástico não reticulado (TPS). Para o desenvolvimento deste trabalho, utilizamos a fécula de mandioca comercial, glicerina e diferentes teores de ácido cítrico para a extrusão reativa. As amostras foram preparadas utilizando 25% m/m de glicerina, teores de 0% até 5% m/m de ácido cítrico e processamento mecânico por extrusão. No processamento utilizando ácido tartárico, os teores foram de 1%, 3% e 5% m/m, sendo a escolha destes teores baseados nos resultados das amostras reticuladas com ácido cítrico. Todas as amostras foram submetidas as análises de espectroscopia de absorção na região do infravermelho, determinação da razão entre bandas de carbonila / carbono – hidrogênio e eter / carbono – hidrogênio, ângulo de contato, intumescimento, análise termogravimétrica (TGA), calorimetria diferencial exploratória (DSC), ensaio mecânico de tração, microscopia eletrônica de varredura (MEV) e difração de Raios – X. Como conclusões parciais, temos a possibilidade de utilização do processamento de extrusão reativa para reticulação do amido em uma única etapa. As amostras que obtiveram melhores resultados nas análises realizadas, se encontram entre a concentração de 1% a 2,5 ~ 3% m/m de ácido cítrico. Entretanto, é observada a dificuldade do processamento e o controle dos paramêtros de processo, como relatados em outros estudos.

In this work was synthezed an adhesive based on polyurethane from the prepolymer 2,4-toluene diisocyanate (TDI) and 2,4-dimethyl-thio-toluenediamine (DMTDA) as chain extender. The partial replacement of the extensor by collagen I was performed. Samples were produced and their physical, mechanical, morphological and thermalproperties were evaluated. The results of the mechanical tests have showed that there are an increase in the percentage of the rigid phase leading to an increase in tensile strength and resistance to organic solvents. The morphological analyzes indicated that the collagen increased the percentage of the rigid phase and promoted the formation of smaller microcells, more evenly distributed in the adhesive. Thermogravimetry analyzes indicated the presence of two stages of degradation, referring to the rigid and flexible phases, respectively. Differential exploratory calorimetry tests indicated that the collagen formulation showed a degree of christality confirmed by the DRX.

This work presents a broad study on the stabilities of several neutral molecular polynitrogens (polyN), with sizes six, eight and ten, focusing in theoretically predicting their usability as high-energy-density materials (HEDMs). If stable enough to be synthesized and stored, these systems may be used as a green source of energy. However, it is very difficult to obtain these structures under mild experimental conditions. One of the main factors that can help this sort of analysis is the predicition of the activation energy barriers of these structures towards unimolecular decomposition. The latter was the basis of the discussions presented throughtout the text. The calculation methodology applied for all the polyN was based on density functional theory (DFT), using exchange and correlation functionals that are known for their high accuracy in predicting energy barriers heights (M06-2X and SOGGA11-X). This made possible a direct and fair comparison between all molecules analysed. The path taken towards achieving this goal started with the search for transition states (TSs) that connected the initial structures to unimolecular decomposition. After finding the TSs, an intrinsic reaction coordinate calculation was carried out for each polyN in order to confirm the decomposition mechanism found. For the most promising structures, a reaction dynamics study was made, in order to check other possible decomposition routes. For this initial and exploratory part of the work, the SOGGA11-X/def2-SVP level of theory was used. A refinement of the results was then performed at the M06-2X,SOGGA11-X/def2-TZVPP levels, being the energies zero pointed corrected. For a structural and electronic analysis of the systems, the average bond lenghts, average bond orders, HOMO-LUMO gaps and asphericities were calculated. From this analysis, it was possible to classify the structures in chains, rings, cages and prismatic cages ones and achieve a correlation between the systems and their energy content. However, it was not possible to assess a clear correlation between the activation energy barriers of the structures with the calculated structural and electronic properties. The results indicate that the prismatic caged polyN can be expected to present higher energy densities and be more stable with respect to unimolecular decomposition. And finally, specific structures could be selected as potential candidates for use as HEDMs.

Rapid population growth and global industrialization have resulted in the progressive generation of industrial effluents with significant concentrations of emerging contaminants or micropollutants such as drugs, personal care products, hormones, and surfactants. These pollutants are considered persistent and difficult to degrade in Wastewater Treatment Plants (WWTP), reaching the aquatic environments after treatment and being found in freshwater. The pharmaceutical wastewaters, in addition to persistence, can cause toxicity to aquatic organisms and inhibit biological activity in wastewater treatment reactors. The research aims to characterize real pharmaceutical wastewater, assessing the efficiency of its current treatment and, if necessary, propose improvements to obtain cost reduction and compliance with the disposal rules. An environmental risk assessment will be carried out to assess the effluent toxicity. The industrial effluent characterization was carried out by compiling historical data of quality parameters contained in laboratory reports of 2019. Historical production data were used to understand the type and quantities of drugs manufactured, the active ingredients and excipients used and, thus, infer about the wastewater's toxicity and biodegradability. The greatest consumption of industrial input was in July and August 2019, with the most consumed principles: anhydrous glucose (33.9%), paracetamol (20.6%), dipyrone (13.9%), benzoate benzyl (8.2%), sodium chloride (6.6%), sodium citrate (4.9%) and potassium chloride (2.6%). The treated effluent at the company's WWTP presented low compliance for COD and pH, being characterized as slightly acidic and, therefore, it was outside the ideal range for the anaerobic treatment used. The effluent temperature, despite following the established limit, was also below the ideal range for the applied treatment. It was possible to infer that the anaerobic reactor used is operating in an acidogenic phase, presenting reduced efficiency when compared to the methanogenic phase, which would be preferable. The treatment has not been effective when presenting COD values higher than the established limit, in addition to the production of bad smell in the area. Starting errors and reactor conditions seem to imply unwanted costs and reduced efficiency.

Currently, supercapacitors (SCs) stand out for being energy storage devices with high-power density. However, to maximize its niche of applications, many efforts have been made to increase its energy density compared to batteries and fuel cells. Furthermore, with the growing demand for miniaturized, thin and flexible electronic devices, the development of electrode materials that meet these characteristics is necessary. In this work, thin and flexible electrodes were developed, called buckypapers (BPs), composed of carbon nanotubes/cellulose nanofibrils (CNT/CNF), in a 1:1 mass ratio, for application in redox SCs. The CNFs used, α-CNFs, β-CNFs and γ-CNFs, were obtained, respectively, from three different cellulosic matrices: Eucaliptus sp, Pinus sp and Bambusa vulgaris. The incorporation of these low cost and biodegradable cellulosic components was carried out to optimize the mechanical and surface properties of BPs. The films were also evaluated for their morphological, thermal and electrical properties. As a result, all BPs showed thermal stability up to 132 ºC, electrical conductivity greater than 0.15 S cm-1 and an increase of 125% in tensile strength and 67% in maximum tensile strength, compared to a BP/without cellulose used as reference. Finally, the BPs were analyzed as redox SCs electrodes in two media: one of them an alkaline medium containing the redox additive potassium hexacyanoferrate(II) (0.1 M K4[Fe(CN)6] in 3.0 M KOH) and the other, an acidic medium containing methylene blue AM as an additive (0.07 M AM in 1.0 M H2SO4). All BPs, α-BP, β-BP and γ-BP, prepared with the different CNFs are stable in acid and basic electrolytes and mediate electron transfer from redox additives. The cell constructed with γ-BP immersed in alkaline redox electrolyte stands out with a specific capacitance (at electrode level) of 167.64 F g-1 (a 5 mA), with a capacitance retention of 98.15% after 12000 galvanostatic charge/discharge cycles. Using the acid redox electrolyte, the best performance in terms of specific capacitance was obtained for α-BP (40.85 F g-1 to 5 mA), with 80.53% capacitance retention after 12000 cycles.

Supercapacitors (SCs) are electrochemical energy storage devices that have a high specific power but retain a low energy density. Strategies to overcome this limitation have been developed in recent years, such as the addition of redox compounds to the electrolyte. Furthermore, in order to expand the number of practical applications of SCs, the construction of solid polymeric electrolytes is of interest, as it allows the assembly of flexible cells and the construction of miniaturized devices in various geometric formats. In this sense, the present work aimed to develop hybrid SCs built with composite electrodes of carbon nanotubes/cellulose nanofibrils and redox gel polymeric electrolytes based on poly(vinyl alcohol). Polymeric electrolytes were added with different redox compounds: methylene blue, hydroquinone and indigo carmine. Polymeric electrodes and electrolytes were characterized, solid cells employing two redox additives (biredox) were constructed and their electrochemical performance evaluated. Finally, the biredox SC achieved specific capacitance, energy density and power density of 7.46 F g-1, 0.55 Wh kg-1 and 360.17 W kg-1, respectively, being able to retain 81.0% of its initial capacitance at the end of 2000 evaluated cycles.
