Antimicrobial and physical-mechanical properties of pectin/papaya puree/cinnamaldehyde nanoemulsion edible composite films
(Food Hydrocolloids, 2014-12-01) [Artigo]
The rising demand for bio-based materials to be used in food packaging has encouraged the development of novel, environmentally-friendly films. Fruit puree has the potential to be incorporated in the film-forming solution ...
Interações discursiva e o uso de analogias no ensino de física
(Investigações em Ensino de Ciências, 2012) [Artigo]
In the last few years, Science Education researchers have shown new ways do conceive the processes of teaching and learning, demanding the displacement from the individual understanding of specific phenomena to a new ...
Electrical and Optical Properties of Conductive and Transparent ITO@PMMA Nanocomposites
(Journal of Physical Chemistry C, 2012-06-14) [Artigo]
In this work, nanocomposite films of indium tin oxide (ITO) nanowires in a PMMA matrix were obtained by tape casting. The electrical, optical and morphological properties of films were studied as a function of the amount ...
A Silsesquioxane Organically Modified with 4-Amino-5-(4-pyridyl)-4H-1,2,4-triazole-3-thiol: Thermal Behavior and Its Electrochemical Detection of Sulfhydryl Compounds
(Journal of Nanomaterials, 2014-01-01) [Artigo]
The octakis(3-chloropropyl)silsesquioxane (SS) was organofunctionalized with 4-amino-5- 4(pyridyl)-4H-1,2,4-triazole-3-thiol. The product formed (SA) was undergo another reactions in two steps, first with copper and so ...
New strategies in the preparation of exfoliated thermoplastic starch-montmorillonite nanocomposites
(Industrial Crops and Products, 2011-11-01) [Artigo]
A simple method based on the combination of the intercalation from solution and melt-processing preparation methods was used to prepare highly exfoliated and compatible thermoplastic starch (TPS) and montmorillonite clay ...

(Polímeros, 2012-01-01) [Artigo]
Neste trabalho foi reportada a caracterização de hidrogéis constituídos por metilcelulose (MC) e poliacrilamida (PAAm) preparados pelo processo de reticulação cruzada. As propriedades espectroscópicas e morfológicas foram ...
Carbon-coated SnO2 nanobelts and nanoparticles by single catalytic step
(Journal of Nanoparticle Research, 2009-05-01) [Artigo]
Several types of carbon nanostructures (amorphous and graphitic), for the coating of SnO2 nanobelts and nanoparticles were obtained by a single catalytic process, during methane, natural gas, and methanol decomposition ...
Novel Aspects of the Purpose-Built Materials Strategy: Evidence of Topographic Template Effect and Oriented Attachment Growth Mechanism
(Journal of Nanoscience and Nanotechnology, 2008-07-01) [Artigo]
We report two novel aspects relating to the growth of oriented 3D arrays of SnO2 nanorods, based on the "purpose-built materials" (PBM) strategy. Under controlled conditions, the substrate acted as a topographic template ...
