Texte intégralIn this work, a new method is presented based on generating and controlling the wavelengths emitted by diode lasers and random lasers. In the first part of this work, resonant feedback random lasing from dye-doped biopolymer films is reported, consisting of a deoxyribonucleic acid and cetyltrimethylammonium (DNA-CTMA) complex doped with DCM dye. In the device, the optical feedback for random lasing is given by scattering centers randomly positioned along the edges of the active area. Scattering elements are either titanium dioxide nanoparticles or random defects at the interface between active polymer and air. Different emission spectra are observed, depending on the geometry of the excited area. A single random resonator with dimensions of 2.6 mm x 0.65 mm is fabricated and random emission with resonant feedback is obtained by uniformly pumping the full device. The second part of this work presents a new method for generating and manipulating contour fringes produced with a single external cavity diode laser in a multi-wavelength speckle interferometer. The external cavity allows tuning two simultaneous emissions, which in turn changes the contour interval of interference fringes and also improves laser stability. A Fourier analysis is applied as an alternative method for acquiring the resulting synthetic wavelength from both emissions.

Texte intégralOptical frequency combs (OFC) have revolutionized various applications in applied and fundamental sciences that rely on the determination of absolute optical frequencies and frequency differences. The latter requires only stabilization of the spectral distance between the individual comb lines of the OFC, allowing to tailor and reduce system complexity of the OFC generator (OFCG). One such application is the quantum test of the universality of free fall within the QUANTUS experimental series. Within the test, the rate of free fall of two atomic species, Rb and K, in micro-gravity will be compared. The aim of this thesis was the development of a highly compact, robust, and space-suitable diode laser-based OFCG with a mode-locked optical spectrum in the wavelength range around 780 nm. A diode laser-based OFCG was developed, which exceeds the requirements with a spectral bandwidth > 16 nm at 20 dBc, a comb line optical power > 650 nW (at 20 dBc), a pulse repetition rate of 3.4 GHz, and an RF linewidth of the free-running pulse repetition rate < 10 kHz. To realize a proof-of-concept demonstrator module, the diode laser-based OFCG was hybrid-integrated into a space-suitable technology platform that has been developed for future QUANTUS experiments. Proof of sufficient RF stability of the OFCG was provided by stabilizing the pulse repetition rate to an external RF reference. This resulted in a stabilized pulse repetition rate with an RF linewidth smaller than 1.4 Hz (resolution limited), thus exceeding the requirement. The developed diode laser-based OFCG represents an important step towards an improved comparison of the rate of free fall of Rb and K quantum gases within the QUANTUS experiments in micro-gravity.

O objetivo deste trabalho foi gerar conhecimento sobre a aplica??o de diferentes t?cnicas na restaura??o de ambientes degradados pela minera??o de ferro. A disserta??o foi estruturada em tr?s cap?tulos, sendo o primeiro uma revis?o de literatura, com intuito de retratar os temas abordados na disserta??o. No segundo, avaliou-se o espa?amento de plantio para Vellozia ramosissima e Pseudobombax campestre no modelo de plantio em Leque, visando gerar conhecimento sobre o manejo dessas esp?cies resgatadas na reintrodu??o a ambientes degradados. Para tal depositou-se sobre uma pilha de est?ril de canga ferruginosa uma camada de topsoil associado ? canga ferruginosa, onde foi instalado o experimento em delineamento sistem?tico tipo ?Leque?, conforme o modelo (IA) proposto por Nelder (1962), em que se avaliou oito espa?amentos de plantio, variando de 2 m?/planta a 9,3 m?/planta. As vari?veis analisadas foram o incremento em altura e di?metro de P. campestre, al?m da sobreviv?ncia de V. ramosissima e P. campestre aos quatro, oito e doze meses ap?s o replantio. Para avaliar os melhores tratamentos foram realizadas an?lises de vari?ncia (ANOVA) a 5% de signific?ncia. Para a sobreviv?ncia realizou-se o teste n?o-param?trico de Kruskal-Wallis a 5% de signific?ncia. As duas esp?cies estudadas apresentaram nos per?odos avaliados sobreviv?ncia acima de 80%. O incremento em altura e di?metro de P. campestre foi crescente ao longo do per?odo avaliado, apresentando uma m?dia geral 34,3 cm e 16,6 mm, respectivamente, durante os doze meses ap?s o replantio. Ressalta-se que os espa?amentos de plantio testados para as esp?cies deste estudo n?o apresentaram diferen?as significativas para todas as vari?veis analisadas. O terceiro cap?tulo teve como objetivo avaliar o potencial do uso da camada superficial de solo ?topsoil? associado ? canga ferruginosa, como alternativa na recomposi??o da cobertura vegetal de uma pilha de est?ril de canga ferruginosa. A comunidade regenerante foi amostrada aos 10 e 18 meses, ap?s a deposi??o do topsoil. Assim, determinou-se a densidade de plantas, composi??o e diversidade flor?stica, al?m de avaliar a din?mica de popula??es e cobertura do solo. A cobertura vegetal proveniente do topsoil ao final do per?odo avaliado apresentou um total de 19.485 indiv?duos pertencentes a 26 fam?lias com 82 esp?cies e seis morfoesp?cies. As fam?lias com maior n?mero de esp?cies foram Asteraceae (16), seguidas de Fabaceae (11) e Poaceae (8). A cobertura m?dia do solo na ?rea experimental foi de 58%, ap?s 18 meses. A utiliza??o do topsoil mostrou-se como uma t?cnica promissora e de extrema import?ncia na indu??o da restaura??o da pilha de est?ril de canga ferruginosa, uma vez que proporcionou a regenera??o natural, recomposi??o da vegeta??o com esp?cies aut?ctones, crescimento satisfat?rio dos indiv?duos e r?pida cobertura do solo ao longo do per?odo avaliado.

This work aimed at generating knowledge on the application of different techniques in the restoration of degraded environments due the iron mining. The master's thesis was structured into three chapters, where the first is a literature review which portrays the issues addressed in the thesis. In the second chapter we evaluated the planting spacing for Vellozia ramosissima and Pseudobombax campestre in fan-shaped planting model, aiming at generating knowledge on the management of the two species when reintroduced in degraded environments. For this purpose we deposited on a pile of sterile ferruginous yoke one topsoil layer associated with the ferruginous yoke, where we conducted the experiment in a fan-shaped systematic design, according to the model (IA) proposed by Nelder (1962), in which were evaluated eight planting spacings ranging from 2 m?/plant to 9.3 m?/plant. We analyzed as variables the increase in height and diameter of P. campestre and the survival of V. ramosissima and P. campestre in the fourth, eighth, and twelveth months after replanting. In order to evaluate the best treatments we performed variance analysis (ANOVA) at 5% significance level. For survival we used the nonparametric Kruskal-Wallis test at 5% significance level. Both the studied species showed survival above 80% in the evaluated periods. The increment in height and diameter of P. campestre was increasing over the studied period, presenting an overall average of 34.3 cm and 16.6 mm, respectively, during the twelve months after replanting. We point out that the plant spacings for the species tested in this study presented no significant differences for all variables. The third chapter aimed at evaluating the potential use of the surface layer of "topsoil" associated with ferruginous yoke, as an alternative in the vegetation cover restoration of a waste pile of ferruginous yoke. The regenerating community was sampled in the 10th and 18th months after the deposit of topsoil. Therefore, we determined the plant density, the composition and the floristic diversity, and we also evaluated the dynamics of populations and soil coverage. The vegetation provided by the topsoil by the end of the studied period showed a total of 19,485 individuals which belong to 26 families with 82 species and six morphospecies. The families with the highest number of species were Asteraceae (16), followed by Fabaceae (11), and Poaceae (8). The average coverage of the soil in the experimental area was 58% after 18 months. The use of topsoil was shown as a promising and extremely important technique in inducing the restoration of the waste pile of ferruginous yoke, once it provided natural regeneration, vegetation restoration with native species, satisfactory growth of individuals, and quick soil coverage over the studied period.

Texte intégralElectrochemiluminescence (EeL) is applied for industrial applications that have considerable potential, such as clinical diagnostic, analytical chemistry, and light-emitting devices, due to selectivity, sensitivity for detection and quantification of molecules through generation of fluorescence light when electric current is applied on the materials. In EeL the electrochemical reaction allows for precise control over the time and position of the light emitting reaction. The control over time allows one to synchronise the luminescence and the biochemical reaction under study and control over position not only improves sensitivity of the instrument by increasing the signal to noise ratio, but also allows multiple analytical reactions in the same sample to be analyzed using an electrode array. The EeL generation fluorescent materials are based on inorganic semiconductor materials for light-emitting devices. Further progress in this EeL field mainly depends on discovery of new advanced materials, interfacial films and nanoparticle coatings, advances in microfluidics leading to total increase in EeL properties. There has been extensive use of polymers for enhancement of EeL properties. Electrochemiluminescent conjugated polymers constitute a new class of fluorescent polymers that emit light when excited by the flow of an electric current. These new generation fluorescent materials may now challenge the domination by inorganic semiconductor materials for the commercial market of light-emitting devices such as lightemitting diodes and polymer laser devices (PLDs).
