Nanopartículas de Fe3O4 funcionalizadas e nanocompósitos de base epóxi
(Universidade Federal de São Carlos, 2015-12-17)
The use of metal oxide nanoparticles in nanocomposite has provided new
and interesting properties and is one of the most promising areas in composites.
Compatibility between these nanoparticles and polymer matrix is the ...
Spray forming of wear and corrosion resistant bimetallic pipes : from the alloy design to the semi- industrial process
(Universidade Federal de São Carlos, 2016-02-29)
The oil exploitation and production at the pre-salt fields in a safety and efficient
way depends on the development of materials that withstand the severe work
conditions found in these fields. For instance, pipes, such ...

(Universidade Federal de São Carlos, 2010-12-10)
A current search for new materials that are economically viable and ecologically correct has led to the implementation of many studies aimed at improving the properties and processability of biodegradable polymers. This ...
Avaliação do dano por choque térmico em concretos refratários via espectroscopia acústica ressonante não-linear
(Universidade Federal de São Carlos, 2012-03-02)
In this thesis the Non-linear Resonant Acoustic Spectroscopy Technique used to evaluate the mesoscopic non-linearity was incorporated into the Impulse Excitation Technique, which is extensively applied to the evaluation ...
Synthesis and characterization of CH3NH3SnI3, Mn doped CH3NH3SnI3 and oxygen-deficient TiO2 as visible-light active semiconductors
(Universidade Federal de São Carlos, 2020-02-14)
CH3NH3SnI3 is an environmentally-friendly (lead-free) perovskite whose synthesis depends on SnI2. Some disadvantages of SnI2 include high cost and tin(IV) contamination. Thus, SnSO4 and C16H30O4Sn are presented as cheaper ...
