A carbon nanotube is a hollow cylinder, which is made of carbon atoms in the hexagonal lattice, which is made by rolling up the grahene sheet in the specific chiral vector direction. This cylindrical structure has outstanding mechanical, electrical thermal properties. Several attempts have been done to obtain the mech…

Los polímeros sintéticos como el PMMA, poliestireno, policarbonato etc., han sido materiales muy atractivos como materia prima para el desarrollo de microestructuras fotónicas. El poli metil metacrilato acido o PMMA (por sus siglas en inglés) genera particular interés, por ser el polímero con mayor transmitancia en el…
Rapid Prototyping methods are often based on additive manufacturing strategies. Depending on the application, it can also be considered the use of a removal manufacturing rapid prototyping methodology. In this paper the authors investigate the possibility of using the ultrasound technology for the shaping of materials…
A sílica híbrida CTA-MCM-41 (onde CTA é o cátion cetiltrimetilamônio) foi empregada, tal como sintetizada, na transesterificação do acetato de etila com metanol. Esta é uma reação modelo para testar catalisadores básicos para a produção de biodiesel a partir de óleos vegetais e gorduras. Os sítios básicos desse catali…

Further development and commercialization of the new generation of optoelectronic and photovoltaic is often limited by the necessity of fabrication of low-cost and efficient transparent conductive electrodes. The development so far is hindered by the conveniently used indium tin oxide (ITO), which suffers from high co…
Sigma phase in well known as a detrimental precipitate which reduces the mechanical and chemical properties of forged components with particular reference to toughness and corrosion resistance. For this reason, temperatures and times of a sigma phase dissolution heat treatment have to be accurately chosen. The optimum…
This work presents some numerical results concerning simulation of failure of laminate composite specimens. In the article two tests to determine ultimate strength in an orthotropic layer, are considered: tension (TT1) and compression (TC1) test. The outcome is compared with experimental data provided by [9,10].
The study of the core behavior during the operation of a nuclear reactor is exceedingly important for nuclear analysis. The fuel burnup causes numerous changes in nuclear fuel due to physical phenomena associated with the interaction of neutrons. The importance of the burnup study is to establish the arrangement and r…
A global objective of current research is to reduce the cost of manufacturing of titanium parts by improving the efficiency of near net-shape powder metallurgy (PM) technologies. These technologies are considered to be very promising as they eliminate waste and high machining costs. However, the cost of titanium compo…
Abstract In this work, mesoporous cellular foams (MCFs) were synthesized and impregnated with different weight percentage of polyethylenimine (PEI) using wet impregnation method. The synthesized adsorbents were characterized using nitrogen adsorption/desorption, SEM, TEM, and FTIR analysis. The CO2 adsorption capacity…
