Síntese de whiskers de CaSiO3 em fluxo salino para elaboração de biomateriais
(Associação Brasileira de Cerâmica, 2012-12-01)
Materials reinforcement by ceramic whiskers has been employed for a long time in a variety of industrial applications. Nevertheless, the materials by which these whiskers are commonly made of (carbide and silicon nitride) ...
Extrusion and characterization of functionalized cellulose whiskers reinforced polyethylene nanocomposites
(ELSEVIER SCI LTD, 2009)
The surface of ramie cellulose whiskers has been chemically modified by grafting organic acid chlorides presenting different lengths of the aliphatic chain by an esterification reaction. The occurrence of the chemical ...
Nonlinear effects generation in suspended core chalcogenide fibre
(2011-06-15)
In this work we report our achievements in the elaboration and optical characterizations of low-losses suspended core optical fibers elaborated from As2S3 glass. For preforms elaboration, alternatively to other processes ...

Thermal tunability of photonic bandgaps in photonic crystal fibers selectively filled with nematic liquid crystal
(2010-12-01)
We address the bandgap effect and the thermo-optical response of high-index liquid crystal (LC) infiltrated in photonic crystal fibers (PCF) and in hybrid photonic crystal fibers (HPCF). The PCF and HPCF consist of solid-core ...
