EFFECT of DIFFERENT SOLID AMOUNTS IN THE PHYSICAL and MICROSCOPICAL PROPERTIES of SiC POROUS CERAMICS
(Trans Tech Publications Ltd, 2008-01-01)
The presence of pores in ceramics is directly related to the chosen forming process. So, in the starch consolidation method, the ceramics show, after burning, pores with morphology similar to that presented by this organic ...
Oxygen Interstitial Dynamics in Bi(2)Sr(2)CaCu(2)O(8+delta) Oxides Measured by Mechanical Spectroscopy
(Trans Tech Publications Ltd, 2008-01-01)
Many researchers became interested in the discovery of Bi(2)Sr(2)CaCu(2)O(8+delta) oxides with critical temperature of around 80 K. It is known that the critical temperature is related to the CuO2 planes of the material. ...
In-situ XANES experiments on Ni K-edge in mesoporous ZrO2-CeO2:Ni.
(Campinas, 2014-03-06)
Ordered mesoporous ZrO2-CeO2 mixed oxides are potential candidates for catalytic applications. These systems, used as anodes in solid oxide fuel cells (SOFC), may lead to better performance of SOFCs, due to an enhancement ...
Polyurethane coating with thin polymer films produced by plasma polymerization of diglyme
(Iop Publishing Ltd, 2009-01-01)
Aqueous-based polyurethane dispersions have been widely utilized as lubricants in textile, shoes, automotive, biomaterial and many other industries because they are less aggressive to surrounding environment. In this work ...
Statistical models for experimental model membranes.
(Águas de Lindóia, 2014-01-29)
Biological membranes are constituted from lipid bilayers and proteins. Investigation of protein-membrane interaction, essential for biological function of cells, must rest upon solid knowledge of lipid bilayer behavior. ...
Structural Evaluation of Mechanically Alloyed (67-x)Ti-xZr-22Si-11B Powders
(Trans Tech Publications Ltd, 2012-01-01)
The present work reports on the structural evaluation of mechanically alloyed Ti-xZr-22Si-11B (x = 5, 7, 10, 15 and 20 at-%) powders. Milled powders and hot-pressed alloys were characterized by X-ray diffraction, electron ...
Organic additives used as binders and pore-forming elements of TIO2 ceramics
(2017-01-01)
When starches/proteins are added to the ceramic matrix, they originate pores whose morphology and sizes are varied. However, ceramic final properties are influenced by the interaction kinetics amongst particulate materials. ...
