Resumo:Micropeneiras são dispositivos de microfiltração que se diferenciam das membranas filtrantes por apresentarem uma distribuição homogênea de poros e baixa rugosidade na sua superfície. Estas características as tornam uma melhor alternativa para processos de separação que requerem alta seletividade na indústria química, de fármacos e de biotecnologia. Neste trabalho desenvolvemos um processo de fabricação de Micropeneiras e Peneiras Submicrométricas utilizando a associação de técnicas de litografia convencional, litografia holográfica e eletroformação. As Micropeneiras eletroformadas em Níquel foram caracterizadas num sistema de microfiltração utilizando fluxo tangencial. Foram estudadas a seletividade da filtração e a resistência ao fluxo para peneiras com mesma área furada e diferentes geometrias de orifícios. Para as peneiras submicrométricas foi possível apenas realizar uma análise da capacidade de retenção de partículas e da pressão de ruptura. Os resultados das medidas de filtração apresentaram uma excelente seletividade na separação de partículas por tamanho, que demonstra a homogeneidade das dimensões dos orifícios das peneiras, fabricadas com esta técnica. O estudo experimental da resistência ao fluxo demonstrou que os modelos atualmente existentes (elaborados para a condição de fluxo frontal) não são adequados para descrever o comportamento das peneiras em regime de fluxo tangencial
Abstract:Microsieves are filtration devices that present a homogeneous distribution of pores, as well as smoother surface in comparison with filter membranes. Because of these characteristics they represent a better choice in processes of separation in the chemistry and biotechnology industries that require high selectivity. In this work we develop a process for fabrication of Microsieves and Submicrosieves. The process associates conventional litography, holographic litography and electroforming techniques. The fabricated Nickel Microsieves were characterized in a cross filtration system. The selectivity and the flow resistance of the microsieves, with the same perforated area and different geometries of the orifices, were analyzed. For the submicrosieves it was possible only to check the capability of retention of particles and the pressure of rupture. The results of the filtration measurements show high selectivity of particles by size, demonstrating the good homogeneity in the orifices of the microsieves. The analysis of the experimental results of the flow resistance measurements showed that the existing models are not appropriate for describing the behavior of microsieve in cross flow

Full textThe uncertainty of the climate and health effects of aerosols is still large, one important reason being lack of knowledge of the primary emissions. This thesis combines laboratory and field experiments, and process modelling in an effort to better quantify the submicrometre aerosol emissions and to understand some of the processes in the atmosphere.
A parameterisation was derived for the source flux of sea salt particles (particles m-2 s-1) in the size range 0.02-2.8 µm dry diameter (Dp), it is the first parameterisation to almost cover two full decades of the submicrometre sea salt aerosol production, and to include the effect of water temperature. This sea salt parameterisation was validated for temperate water in the 0.1-1.1 μm Dp range using in situ size resolved emissions of marine aerosol particles, which were measured with the eddy covariance (EC) method. For periods sampled air was heated to 300ºC in order to evaporate semi-volatile organics and isolate the sea salt fraction. Comparisons with the total aerosol emissions suggest that in these emissions organic carbon and sea salt are internally mixed in the same particles. Finally an aerosol dynamics model was modified for marine conditions. In the model parameterised emissions of sea salt was included together with aerosol dynamics, chemistry and clouds representative for the marine boundary layer. The sea salt emissions are together with secondary sulphate, and cloud processing able to reproduce a typical marine aerosol size distribution and cloud condensation nuclei population.
Measurements with the EC method of the road traffic related aerosol source number flux for Dp>0.011 µm show that the major part of the aerosol fluxes is due to road traffic emissions. Both an emission factor for the whole fleet mix in Stockholm (1.4x1014 vehicle-1 km-1) and separate emission factors for light- and heavy-duty vehicles (HDV) were deduced. The result shows that during weekdays 70-80% of the emissions come from HDV.

Polymer particles in the nanometer range are of fundamental interest today, especially when used as carrier systems in the controlled release of drugs, cosmetics and nutraceuticals, as well as in coating materials with magnetic properties. The main objective of the present study concerns the production of submicron particles of poly (methyl methacrylate) (PMMA) by crystallization of a polymer solution by thermally controlled cooling. In this work, PMMA solutions in ethanol and 1-propanol were prepared at different concentrations (1% to 5% by weight) and crystallized at different cooling rates (0.2 to 0.8 ? C / min) controlled linearly. Analysis of particle size distribution (DLS / CILAS) and scanning electron microscopy (SEM) were performed in order to evaluate the morphological characteristics of the produced particles. The results demonstrated that it is possible to obtain submicron polymer perfectly spherical particles using the technique discussed in this study. It was also observed that, depending on the cooling rate and the concentration of the polymer solution, it is possible to achieve high yield in the formation of submicron particles. In addition, preliminary tests were performed in order to verify the ability of this technique to form particulated carrier material with magnetic properties. The results showed that the developed technique can be an interesting alternative to obtain polymer particles with magnetic properties

Full textNanodiamonds (NDs) are the subject of extensive research in biomedical, military, and quantum mechanics applications. To produce these NDs, the detonation of a RDX/TNT mixture, commonly referred to as hexolite, is frequently employed. However, to achieve NDs with high-performing physicochemical properties, it is essential to begin with finely divided hexolite particles and to ensure that the mixture is both intimate and homogeneous. In pursuit of this goal, the NS3E laboratory has developed a recrystallization process based on Spray Flash Evaporation (SFE). Despite this advancement, the influence of various operating conditions on the physicochemical characteristics of the resulting particles remains poorly understood. Gaining a deeper understanding of these influences would enable more precise control over the properties of the recrystallized particles. This thesis therefore aims to address these issues by employing in situ analytical techniques, such as shadowgraphy and Phase Doppler Particle Analysis (PDPA).The research is organized around two principal axes. The first focuses on an in-depth investigation of the physicochemical phenomena underlying the flash evaporation of a solvent (acetone) and examines how the presence of a solute (hexolite) affects the behavior of the acetone spray. The second axis centers on characterizing the resulting hexolite particles—specifically their sensitivity, size, and morphology—and elucidating the underlying reasons for these properties considering the spray’s behavior
