Novel Ni-Ce-Zr/Al2O3 Cellular Structure for the Oxidative Dehydrogenation of Ethane
(MDPI, 2017-11)
A novel gamma-alumina-supported Ni-Ce-Zr catalyst with cellular structure was developed for oxidative dehydrogenation of ethane (ODHE). First, powdered samples were synthesized to study the effect of both the total metal ...
Estabilización de espumas de aluminio con partículas de alúmina metalizadas con cobre
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-02)
In general, a process of foam from foamable compacted consists of three basic steps: formation of pores; growth; and collapsing. In this work, the addition of alumina particles to the porous structure being investigated ...
Síntesis de soportes de alúmina anodizada auto-arreglada
(Universidad Michoacana de San Nicolás de Hidalgo, 2012-08)
This paper deals with the controlled anodization of aluminum in obtaining meso-porous membranes with features honeycomb system and characterization of the structural parameters of the pores formed. Research attends one of ...
Permeability optimization and performance evaluation of hot aerosol filters made using foam incorporated alumina suspension
(ELSEVIER SCIENCE BV, 2009)
Porous ceramic samples were prepared from aqueous foam incorporated alumina suspension for application as hot aerosol filtering membrane. The procedure for establishment of membrane features required to maintain a desired ...
Preparation, characterization and biological studies of β-TCP and β-TCP/Al2O3 scaffolds obtained by gel-casting of foams
(2017-07-01)
Replacement tissues for tissue engineering can be produced by seeding human cells onto scaffolds. In order to guarantee adequate bio-compatibility, porosity and mechanical resistance for promoting cellular growth, proliferation ...

Ceramics with porous cellular structure, called ceramic foams, have a potential use in several
applications, such as: thermal insulation, catalyst supports, filters, and others. Among these
techniques to obtain porous ...
Estruturas celulares de mulita sintetizadas a partir da cinza da casca de arroz
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia de MateriaisUTFPR, 2019-07-01)
The rice husk does not present nutritional and commercial values, so it ends up being consumed by the rice producers as energy source for internal processes, culminating in the generation of a harmful residue to the ...
Desenvolvimento de um equipamento para avaliar propriedades elásticas de cerâmicas refratárias a altas temperaturas pelo método de ressonância de barras.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ciência e Engenharia de Materiais - PPGCEM, 2002-09-12)
The knowledge of the elastic properties has been of fundamental
importance for the understanding of the limitation of the useful life of structural
refractory ceramics. Those properties characterize the elastic rigidity ...
