Estudo de filmes de poli(ácido lático) obtidos por fiação por sopro em solução reforçados com nanocristais de celulose
(Universidade Federal de São Carlos, 2016-07-15)
Solution blow spinning is a technique to produce micro- and nano-scale fibers, forming films with high porosity and surface area. Chemical modifications or the incorporation of nanostructures in these fibers can improve ...
Efeitos da diminuição do tamanho médio de partículas da frita nas propriedades dos esmaltes cerâmicos visando aplicação na esmaltação digital
(Universidade Federal de São Carlos, 2017-08-04)
Nowadays Brazil is the second largest producer and consumer of ceramic tiles in the world. In the process of tile’s production, the decoration and glazing play a prominent role since they are responsible for technical and ...
Contribuição para a melhoria no desempenho ambiental de porcelanatos: Avaliação de Ciclo de Vida (ACV) e o uso de fundentes enérgicos
(Universidade Federal de São Carlos, 2019-08-01)
Whether due to growing environmental awareness or legal and market requirements, the quest for sustainable development has leading to the need to improve processes and products. In this scenario, the general objective of ...
Identificação das variáveis que ocasionam a variação de tonalidade utilizando a técnica de decoração por cilindros de silicone gravados a laser
(Universidade Federal de São Carlos, 2015-11-30)
A major problem in the production of ceramic tiles for coating is the variation of
tonality. The determination of their origin within the entire production process and to
minimize its occurrence by the manufacturer is ...
Zircônia CO-dopada por compensação de cargas nos sistemas (ZrO2)1-(x+y)(InO1,5)x(MOz)y com MOz = TaO2,5, NbO2,5, MoO3 ou WO3, como revestimento para barreira térmica
(Universidade Federal de São Carlos, 2016-09-30)
InO1.5-stabilized zirconia (InSZ) is a potential hot corrosion resistant thermal
barrier coating (TBC). However, the thermal instability prevents real applications
of InSZ-based TBC. This thesis investigates the hypothesis ...
Estudo do processo de soldagem a ponto por fricção de juntas dissimilares entre ligas de alumínio e titânio
(Universidade Federal de São Carlos, 2016-12-09)
Multimaterial structures between aluminum and titanium alloys are a
technologically attractive field of research and their increasing use in the
transportation sector for weight and emission reduction is part of the ...
Comportamento elétrico de nanocompósitos baseados em copolímeros em bloco e nanotubos de carbono
(Universidade Federal de São Carlos, 2017-06-23)
In this work conductive polymer nanocomposites (CPNs) based on block copolymers and multi walled carbon nanotubes (MWCNT) were obtained. Two of the copolymers were commercial: polystyrene-b-polybutadiene-b-polystyrene ...
Abordagem termodinâmica do transporte iônico e da relaxação estrutural em vidros fosfatos de prata
(Universidade Federal de São Carlos, 2016-09-12)
Ionic conductivity in glasses was first discovered and demonstrated by
Warburg in 1884, but although it has been studied for over a century, the
mechanisms underlying ionic conduction in glasses are not yet entirely ...
Deformação piroplástica em porcelanatos
(Universidade Federal de São Carlos, 2016-09-09)
In recent years porcelain stoneware tiles showed the highest growth in
production and consumption in ceramic industry sector. To achieve low
porosity, which ensures the high performance of the product, is required ...
Comportamento mecânico em fadiga da liga de titânio beta metaestável Ti-5553
(Universidade Federal de São Carlos, 2016-10-14)
The microstructure of metastable beta Ti alloys is a decisive factor that
governs their properties and, therefore, the assessment of the relation between
the microstructure and the fatigue response means an advance in ...
