1. Using glycerol produced from biodiesel as a plasticiser in extruded biodegradable films
AbstractThe demand for renewably sourced biodegradable materials has increased the need to produce materials that combine appropriate functional properties at competitive costs. Thermoplastic starch and polyester blends are an interesting alternative to current materials due to the low cost of starch and the functional properties and processability of the re

2. TPS Nanocomposite reinforced with MFC by melting process
Bionanocomposites of thermoplastic starch (TPS) reinforced with microfibrilated cellulose (MFC) were prepared by melt processing. MFC was prepared from eucalyptus wood pulp by a process combining cryogenic milling in high shear mixers, chemical treatment with sodium hydroxide and ultrasound treatment. The never dried MFC was then dispersed in native starch a

3. Nanocompósitos ternários de amido termoplástico e poli(Butadieno maleatado)
Liquid polybutadiene (PBLH) was modified with maleic anhydride (MA). The material (PBLHM) was characterized and used to prepare hybrid materials by blending with glycerol-plasticized cassava starch (TPS) and an organophilic clay at 5 wt% content. Processing was performed by extrusion under mild conditions and led to TPS/PBLHM/clay hybrids, at 95/5 to 85/15 T

4. Preparation and characterization of thermoplastic starch/zein blends
Blends of starch and zein plasticized with glycerol were prepared by melting processing in an intensive batch mixer connected to a torque rheometer at 160 °C. The resulting mixtures were compression molded and then characterized by scanning electron microscopy, differential scanning calorimetry, wide-angle X ray diffraction and water-absorption experiments.

5. Utilization of cassava starch for the preparation of new termoplastic materials / Utilização de amido de mandioca na preparação de novos materiais termoplásticos
In this work it was studied the development of thermoplastic starches (TPS) prepared from raw cassava root and its derivatives, starch and bagasse (residue). The TPS were prepared by melt-processing employing glycerol as plasticizer in distinct proportions. It was searched for alternatives that could improve both, the mechanical performance and resistance to

7. Preparation and characterization of termoplastic starches / Preparação e caracterização de amidos termoplásticos
Este trabalho teve como objetivo estudar o processo de plasticização do amido via mistura física e por reação química para a produção de novos materiais. A plasticização via mistura física foi realizada empregando-se como agentes plasticização diferentes compostos hidroxilados. Os amidos termoplásticos (TPS) foram processadas em misturador inte

8. Registro de imagens de documentos antigos. / Image registration of ancient documents.
Este trabalho descreve uma técnica para alinhamento de imagens de documentos antigos. Para que seja possível alinhar duas imagens da mesma página de um documento uma técnica de registro de imagens é utilizada. As imagens mencionadas possuem diferenças de aquisição que incluem translação, rotação e distorções geométricas. A técnica de registro
