Photoluminescence activity of Ba1-xCaxTiO3: dependence on particle size and morphology
(Journal Of Materials Chemistry C, 2014-01-01) [Artigo]
It was shown that the higher photoluminescence emission of Ba1-xCaxTiO3 titanates is associated with the substitution of Ba by Ca, for the composition x = 0.75, which interferes with structural ordering, morphology and ...

Obtenção de oligossacarídeos N-ligados às glicoproteínas dos líquens Sticta tomentosa e Sticta damaecornis
(Eclética Química, 2002-01-01) [Artigo]
As glicoproteínas dos líquens Sticta tomentosa e Sticta damaecornis foram extraídas utilizando-se tampão específico e fracionadas pela adição crescente de sulfato de amônio. Dentre os diferentes cortes de saturação obtidos, ...
Manipulation of anchoring strength in an azo-dye side chain polymer by photoisomerization
(Physical Review E, 2003-04-01) [Artigo]
The generation of surface anisotropy by photochemical means has been proposed as an attractive method to align liquid crystals. In this paper, we present an experimental study of the alignment induced on a liquid crystal ...
Tuning the activity of alternative Ru-based initiators for ring-opening metathesis polymerization of norbornene and norbornadiene by the substituent in 4-CH2R-piperidine
(Journal of Molecular Catalysis A: Chemical, 2014-04-01) [Artigo]
The novel [RuCl2(PPh3)(2)(4-CH2R-pip)] complexes, with R=H (complex 1), Ph (2) or OH (3), were synthesized and applied as initiators for ROMP of norbornene (NBE) and norbornadiene (NBD) under different reaction times, ...
Briquetting of charcoal from sugar-cane bagasse fly ash (scbfa) as an alternative fuel
(Waste Management, 2010-05-01) [Artigo]
Brazil is the largest worldwide producer of alcohol and sugar from sugar-cane and has an extensive alternative program for car fuel which is unique. The objective of this work is to offer one management option of a solid ...
Detection of trace levels of atrazine using surface-enhanced Raman scattering and information visualization
(Colloid And Polymer Science, 2014-11-01) [Artigo]
The detection of trace amounts of pesticides is essential for the quality control of waters, particularly with their inevitable increasing use with the growing demand for food. In this study, we report on the detection of ...
Segmentation of Scanning Electron Microscopy Images From Natural Rubber Samples With Gold Nanoparticles Using Starlet Wavelets
(Microscopy Research and Technique, 2014-01-01) [Artigo]
Electronic microscopy has been used for morphology evaluation of different materials structures. However, microscopy results may be affected by several factors. Image processing methods can be used to correct and improve ...
Brincando com a física: ensino lúdico na forma de teatro em espaço não formal
(Congresso de extensão universitária da UNESP, 2015-09-21) [Trabalho apresentado em evento]
Physics teaching, using different tools combined with environments outside the classroom, can become widely pleasant and efficient, both for the teacher and for the students. Thus, it has been developed a project named ...
