Preparación y caracterización de almidón de mandioca termoplástico combinado con poli (ácido láctico). Estudio del comportamiento producido por el agregado de grafeno como material de carga
(2019-03-29)
El poli (ácido láctico) (PLA) y el almidón de mandioca son biopolímeros derivados de fuentes renovables y biodegradables con adecuadas propiedades para ser utilizados en el área de envases para alimentos, insumos médicos ...
NAADP-sensitive two-pore channels are present and functional in gastric smooth muscle cells
(Churchill Livingstone, 2014-08-01)
Nicotinic acid adenine dinucleotide phosphate (NAADP) has been identified as an important modulator of Ca2+ release from the endo-lysosomal system in a variety of cells by a new and ubiquitous class of endo-lysosomal ion ...
Improving the toughening in poly(lactic acid)-thermoplastic cassava starch reactive blends
(John Wiley & Sons Inc, 2018-04)
Poly(lactic acid) (PLA), a physical blend of PLA and thermoplastic cassava starch (TPCS) (PLA-TPCS), and reactive blends of PLA with TPCS using maleic anhydride as compatibilizer with two different peroxide initiators ...
Toughening of poly(lactic acid) and thermoplastic cassava starch reactive blends using graphene nanoplatelets
(Molecular Diversity Preservation International, 2018-01)
Poly(lactic acid) (PLA) was reactively blended with thermoplastic cassava starch (TPCS) and functionalized with commercial graphene (GRH) nanoplatelets in a twin-screw extruder, and films were produced by cast-film extrusion. ...
Graphene modifies the biodegradation of poly(lactic acid)-thermoplastic cassava starch reactive blend films
(Elsevier, 2019-06)
Biobased blend films produced from poly(lactic acid) (PLA), thermoplastic cassava starch (TPCS), and reinforced with graphene nanoplatelets (GRH) were evaluated in compost and inoculated vermiculite under composting ...
Modelagem de um transformador de potencial capacitivo para avaliação de comportamento em regime transitório
(2020)
Este trabalho apresenta os resultados da implementação de uma modelagem em regime transitório de um transformador de potencial capacitivo (TPC). Para isso, realizaram-se três etapas fundamentais: execução de ensaios elétricos ...
Effect of extraction conditions on total phenolic content and antioxidant capacity of pretreated wild peumus boldus leaves from chile
(INST CHEMICAL ENGINEERS, 2014)
We studied the effect of both heat-drying and freeze-drying on the recovery of total phenolic compounds (TPCs) and antioxidant capacity from leaves of Peumus boldus Molina (Boldo), an endemic tree of Chile, using DPPH ...
Thermal performance curves under daily thermal fluctuation: A study in helmeted water toad tadpoles
(2017)
Most research in physiological ecology has focused on the effects of mean changes in temperature under the classic "hot vs cold" acclimation treatment
