Montmorillonite (MMT) effect on the structure of poly(oxyethylene) (PEO)-MMT nanocomposites and silica-PEO-MMT hybrid materials
(Elsevier B.V., 2006-09-15)
In this work we report the effects of incorporation of variable amounts (0.5-25%w/w) of montmorillonite in poly(oxyethylene) based materials in order to decrease the polymer crystallinity. Two different classes of materials ...
Structure of SnO2 alcosols and films prepared by sol-gel dip coating
(Elsevier B.V., 2001-05-01)
To obtain SnO2 films to be used for surface protection of fluoride glasses, a non-aqueous sol-gel route for the preparation was developed. An ethanolic SnO2 colloidal suspension was prepared by thermohydrolysis of SnCl4 ...

Aproveitamento energético de biogás gerado em reatores UASB tratando esgoto doméstico
(Universidade Federal de Minas GeraisUFMG, 2011-05-19)
The research aimed at evaluating the main alternatives for energy recovery from biogas produced in upflow anaerobic sludge blanket (UASB) reactors treating domestic wastewater. The primary focus was related to cogeneration ...
Qualidade microbiológica, físico-química e perfil eletroforético de amostras de soros de queijo produzidos no norte de Minas Gerais
(Universidade Federal de Minas GeraisUFMG, 2017-09-29)
Cheese, by volume of production, is the main lactic derivative produced in Brazil. During its production, a serum release occurs, which is still considered a by-product of the cheese industry. Cheese serum is important ...
Resultados postoperatorios en apendicitis aguda complicada según la técnica de lavado vs secado de cavidad abdominal en pacientes pediátricos
(Universidad de Guayaquil. Facultad de Ciencias Médicas. Escuela de Graduados, 2023)
La apendicitis aguda es la patología quirúrgica abdominal más común en el mundo y el tratamiento entre el lavado vs secado de la cavidad abdominal en la peritonitis secundaria constituye una preocupación permanente de los ...
Catalisadores de Ni suportados em óxidos sintetizados com líquido iônico: atividade catalítica na tri-reforma do metano
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2019-04-11)
Tri-reforming reaction is a new method to use and convert CO2 from industrial plants effluents. The tri-reforming involved reactions are two endothermic reactions, the steam and dry reforming and the partial methane oxidation ...
Porous mullite ceramics formed by direct consolidation using native and granular cold-water-soluble starches
(Wiley, 2014-04)
In this article, the processing and microstructures of porous mullite bodies prepared by modifying the conventional route of the starch consolidation casting method were studied. The proposed route, called the “soluble ...
Síntese e caracterização de vidros obtidos por sol-gel para aplicação em cimentos de ionômero de vidro
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2019-10-16)
Glass ionomer cements are materials used in dentistry in restorations, cementations or lining. They are formed by a curing reaction between the inorganic glass particle and a polymeric acid. The sol-gel process is a synthesis ...
