1. Manufacturing and characterization of sustainable macroporous glass foams
Abstract This work produced glass foams from soda-lime glass bottles, bentonite, and alumina by the replica method. Compositions with different contents of bentonite (5, 10, 15, and 20 wt%) were prepared and heat-treated at 800 °C. In the alumina-added compositions, 50 wt% of the bentonite was replaced by the alumina. The influences of the content of benton

2. Avaliação da adição de resíduos de vidro sodo-cálcico e erva-mate em matriz cerâmica
Resumo O presente trabalho avaliou os efeitos da adição de resíduos de vidro sodo-cálcico e de erva-mate sobre a absorção de água, porosidade e resistência mecânica de um material cerâmico. Os pós homogeneizados foram compactados por prensagem uniaxial e submetidos a queima de 900 e 1100 °C a 2 °C.min-1. Os resultados mostraram que a adição de

3. Sustainable Glass Foams Produced from Glass Bottles and Tobacco Residue
In this work, discarded soda-lime-silica glass bottles and tobacco residue (after oil extraction to produce biodiesel) were prepared in different formulations to obtain glass foams. The formulated compositions were homogenized and uniaxially compacted at 40 MPa then fired at 850 ºC and 900 ºC for 60 min to investigate the effects of tobacco residue and tem

4. Characterization of Vitrocrystalline Foams Produced from Discarded Glasses and Recycled Polystyrene Spheres
In this work, discarded soda-lime glasses (from glass bottles) and recycled polystyrene (PS) spheres (d50 < 300 µm) were successfully converted into vitrocrystalline foams for thermal insulation applications. Physical and chemical properties of the selected and prepared raw materials (wastes) were characterized. Batches containing well mixed glass powder (d

5. PREPARATION OF ZEOLITE X COATINGS ON SODA-LIME TYPE GLASS PLATES
Abstract The dissolution of glass in highly alkaline reaction mixtures and the impact of this phenomenon on zeolite coating formation were investigated. Coating samples were prepared and characterized by X-ray diffraction (XRD), field emission gun scanning electron microscopy (FEGSEM) and thermogravimetry (TG). It was demonstrated that zeolite X coatings mig

6. Study of the Influence of Chemical Composition on the Pozzolanicity of Soda-lime Glass Microparticles
The use of residues, in partial or total substitution of aggregates or binders in concrete, presents interesting possibilities for obtaining eco-efficient concretes. Research has investigated the use of glass residue in Portland cement composite, whether as an aggregate or a supplementary cementitious material. However, there is still no consensus on the inf

7. Heterojunction between Al2O3 and SnO2 thin films for application in transparent FET
Alternative materials for use in electronic devices have grown interest in the past recent years. In this paper, the heterojunction SnO2/Al2O3 is tested concerning its use as a transparent insulating layer for use in FETs. The alumina layer is obtained by thermal annealing of metallic Al layer, deposited by resistive evaporation technique. Combination of und

8. FABRICATION AND OPTICAL AND MORPHOLOGICAL CHARACTERIZATION OF GOLD NANOPARTICLES ON GLASS SUBSTRATE / FABRICAÇÃO E CARACTERIZAÇÃO ÓPTICA E MORFOLÓGICA DE NANOPARTÍCULAS DE OURO EM SUBSTRATO VÍTREO
Nesta dissertação descrevemos a preparação de nanopartículas (NPs) de ouro através do aquecimento de filmes finos de ouro depositados em substratos de soda-lime pela técnica Magnetron Sputtering. Foi realizado um estudo para cinco espessuras diferentes variando entre (6¿20) nm. Descrevemos também a caracterização morfológica e óptica (linear e n

9. Estudo de traços de fissão em vidro utilizando-se microscopias de força atomica e eletronica de varredura : inferencia da estrutura de traços latentes a partir de traços atacados / Glass fission track analysis by AFM and SEM : inferring latent track structure trough etched tracks
A study on the geometric evolution of 235U induced fission tracks in a soda-lime glass was made. It was necessary to know about the geometric model for structure evolution of fission tracks in isotropic materials. This model is based on the competition of two chemical etching rates: one in the bulk material (VB) and another in each fragment trajectory (VT).

10. GLASS AND GLASS-CERAMICS WITH HIGH METAL CONCENTRATION OF FROM INDUSTRIAL WASTES / Vidros e vitrocerâmicos com alta concentração de metais obtidos a partir de resíduos industriais
The reuse of industrial waste materials is considered as an important source of raw-materials to be employed at new products. However proper criteria is needed in order to obtain vitreous materials from industrial solid wastes like solid galvanic waste (metallurgical industry) as main raw material. Ajusting the composition silica fine powder (ceramic industr

12. DETERMINAÇÃO DAS PROPRIEDADES MECÂNICAS E CARACTERIZAÇÃO DE FILME FINO PRODUZIDO POR IMPREGNAÇÃO FORÇADA
In this work has been developed a new way to impregnate using high pressure. Thin film were obtained in soda-lime glass surface when it were used Co3O4, Al2O3, TiO2 and SnO2 as a oxides deposited, across a furnace confectioned for this experiment. SnO2 was results of two different chemical methods of synthesis. It was able to control tree variable: temperatu
