Estudo da molhabilidade de tecidos 100% poliéster tratados em plasma N2/O2 em função do seu envelhecimento natural
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em Ciência e Engenharia de MateriaisProcessamento de Materiais a partir do Pó; Polímeros e Compósitos; Processamento de Materiais a part, 2006-06-14)
This work reports the influence of the poly (ethylene terephthalate) textile surface modification by plasmas of O2 and mixtures (N2 + O2), on their physical and chemical properties. The treatment was carried out in a vacuum ...
Alloying and surface composition of model Pd-Ag films synthesized by electroless deposition
(Pergamon-Elsevier Science Ltd, 2012-04)
PdAg model films and real composite membranes were prepared by sequential electroless deposition on top of porous stainless steel supports. Their surface properties were investigated by X-ray photoelectron spectroscopy ...
Photo-induced effects in Ge25Ga10S65 glasses studied by XPS and XAS
(Elsevier B.V., 2014)
Effects of helium ion irradiation on fluorinated plasma polymers

Processing and dimensional changes of cement based composites reinforced with surface-treated cellulose fibres
(Amsterdam, 2013-03)
The objective of the present work is to evaluate the impact of the surface grafting of cellulose fibres on
the processing, dimensional stability and mechanical performance of fibre–cement composites. The surface
modification ...
Surface properties and catalytic behavior of Ru supported on composite La2O3-SiO2 oxides
(Elsevier Science, 2009-11)
Binary La2O3-SiO2 supports were employed to obtain active, stable Ru catalysts with high dispersions for the dry reforming of methane. Supports with 15, 27, 40 and 50 wt. % of La2O3 were prepared by incipient wetness ...
New findings for the composition and structure of Ni nanoparticles protected with organomercaptan molecules
(American Chemical Society, 2013-03-21)
Here we explore the synthesis of alkanethiolcoated Ni NPs following the one-phase reaction method by Brust et al.1 The reduction of NiCl2 with NaBH4 in the presence of dodecanethiol (C12SH) yields a complex product that ...
Cross-Section Analysis of the Composition of Sprayed Cu 2 ZnSnS 4 Thin Films by XPS, EDS, and Multi-Wavelength Raman Spectroscopy
(Wiley VCH Verlag, 2018-12)
A detailed cross-section analysis of the chemical composition of sprayed Cu 2 ZnSnS 4 thin films is presented. X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS), and Raman ...
Analysis of chemical polymerization between functionalized MWCNT and poly(furfuryl alcohol) composite
(2018-01-01)
In this study, the chemical interaction between functionalized carbon nanotuboes with carboxyl groups (CNT-f) and the subsequent addition of furfuryl alcohol (FA) and mixture with poly(furfuryl alcohol) (PFA) resin was ...
