As part of the process for the establishment of a germplasm bank of timber, nontimber Amazonian species that contribute to the food security of the region, the characterization of eleven plant species was carried out; consisting of definition of uses, fruiting periods and experiences of propagation, during the period from June to October 2017; To advance with the analysis of factors that directly affect the storage behavior of germplasm (seeds), five plant species were selected that were harvested during the period from September to November 2017, Carapa guianensis, Oenocarpus bataua, Bactris gasipaes, Scleronema praecox and Socratea exorrhiza, to which were made: location of seed trees, harvesting, cleaning, previous drying and determination of the moisture content of the seeds. The species Scleronema praecox had high moisture content, during the previous drying it was observed a rapid ...

La primera parte de esta Tesis de Maestría consiste en entender las propiedades catalíticas y de carácter no enzimático de nanopartículas magnéticas (NPM) de óxido de hierro sintetizadas por el método de descomposición térmica en la creación de sensores que permiten detectar analitos tales como el peróxido de hidrógeno (H2O2) y ácido cítrico. La creación del sensor de H2O2 es llevado a cabo mediante la deposición capa por capa [Layer-by-Layer (LbL)] de las NPM suspendidas y funcionalizadas en medio acuoso con la amina cuaternaria y a su vez surfactante Bromuro de cetiltrimetilamonio (Cetyltrimethylammonium bromide-CTAB) y con el polímero poli-aniónicosodio 4-estireno-sulfonato (sodium 4-styrenesulfonate PSS) vía interacción electrostática sobre el sustrato conductor óxido de estaño dopado con flúor (Fluorine doped Tin Oxide-FTO). La sensibilidad del sensor es est...
