Stacking faults in SiCf/SiC composite obtained by chemical vapor reaction process
(2008-12-01)
SiC fiber-reinforced SiC matrix composite (SiCf/SiC) is one of the leading candidates in ceramic materials for engineering applications due to its unique combination of properties such as high thermal conductivity, high ...
Calcium modified lead titanate/poly-ether-ether-ketone composite for acoustic emission sensors
(2005-12-01)
Composites made of calcium modified lead titanate ceramic powder and poly (ether-ether-ketone) high performance polymer matrix were prepared in the film form using a hot press. The acoustic and electromechanical properties ...
Study of ITO@PMMA composites by transmission electron microscopy
(2011-10-03)
ITO nanowires were synthesized by carbothermal reduction process, using a co-evaporation method, and have controlled size, shape, and chemical composition. The electrical measurements of nanowires showed they have a ...
Slurry sample injection for determination of ferrite nanocolloids chemical composition by ICP spectrometry
(2007-08-23)
This work proposes a new method to determine the chemical composition of magnetic ferrite nanoparticles by the slurry injection technique using the inductively coupled plasma optical emission spectroscopy. In this way, ...
Biomass production and chemical composition of Lippia alba (Mill.) NEBr. ex Britt & Wilson in leaves on different plant parts in different seasons
(International Society Horticultural Science, 2002-01-01)
Lippia alba, family Verbenaceae, is widely spread in Central and South American. It's a shurb with a quadrangular branch reaching 1,7m tall. The leaves are membranaceous, petiolate, pubescent with a strong flavor. It's ...

Methanol oxidation on PtRu/C electrocatalysts prepared by a microemulsion method
(2007-12-01)
PtRu/C nanocatalysts were prepared by a microemulsion method using different values of water/surfactant molar ratio in order to get different particle sizes. Crystallite sizes and structural properties were determined by ...
Evaluation of ten tropical grasses in the northwest region of the state of Sao-Paulo Brazil
(Fundação Estudos Agrarios Luiz Queiroz (fealq), 2001-01-01)
The experiment was carried out in the northwest region of the State of São Paulo-Brazil to evaluate ten grasses recently introduced in the region. The grasses studied were: Cynodon nlemfuensis cv. Tifton 68, C dacrylon cv. ...
