(Universidad de Chile, 2018)En esta Tesis se propuso la preparación y caracterización de cristales de compuestos de inclusión (CI) de β-ciclodextrina (β-CD) con moléculas huéspedes que poseen un grupo funcional –COOH y su interacción con nanobarras ...
-
(2012)Collision processes between single gold and rhodium atoms and gold and rhodium nanoclusters, respectively, are used to study the interplay between the large elastic energies and the much smaller magnetic interactions. The ...

(Sociedad Chilena de Química, 2017)Single crystals of 1,3-bis(cyanomethoxy)calix[4]arene (1) were grown from Chloroform/Methanol mixture and these were nanodecorated with colloidal gold nanoparticles (AuNps). The single crystals were then characterized by ...
-
(2023)La reducción y estabilización de nanopartículas (NPs) metálicas es determinante para su posterior aplicación en medicina, en la industria del petróleo y como tratamiento alternativo para la remoción de contaminantes en ...
-
(Elsevier, 2020)Polycrystalline hollow nanoparticles present a unique combination of strength and flexibility. However, the exact role displayed by their grain structure in mechanical properties has not been yet fully understood. Here, ...
-
(Universidad de Chile, 2020)El creciente interés por el uso de materiales que generen el menor impacto al medio ambiente y que permitan versatilidad en su uso, han hecho que las nanoarcillas sean una opción altamente viable, gracias a sus propiedades ...

(Elsevier, 2016)In this work, we have studied the Pb2+ sorption capacity of Zeolite (Z) and Montmorillonite (Mt) functionalized with nanoscale zero-valent iron (nZVI), at 50% w/w, obtained by means of an impregnating process with a solvent ...
-
(2011)Pyrolysis of molecular precursors containing vanadium organometallic and cyclic phosphazene affords mixtures of nanostructured vanadium oxides and pyrophosphates. The products from the molecular precursor [N3P3(OC6H5)5OC ...
-
(Elsevier Ltd., 2009-02-08)A series of naphthylisopropylamine and N-benzyl-4-methylthioamphetamine derivatives were evaluated as monoamine oxidase inhibitors. Their potencies were compared with those of a series of amphetamine derivatives, to test ...
-
(2014)In this paper, an aspect of the national discourse of the early twentieth century in the territory of Tacna and Arica, in its sovereignty dispute between Chile and Peru, is analyzed. The corpus of the analysis focuses on ...
-
(Universidad Austral de Chile, Facultad de Ciencias Forestales, 2020)Native forest replacement by exotic forestry plantations and fragmentation may have different consequences for biodiversity. In the transition zone between the Mediterranean and Temperate Regions of Chile, native forests ...
-
(New Zealand Plant Protection Society, 2015)© 2015 New Zealand Plant Protection Society (Inc.). In New Zealand, unmanaged bees species can be important crop pollinators, but their abundance and distribution is poorly known within hybrid carrot seed crops. Standardised ...
-
(Elsevier, 2021)The sustainable provision of pollination services in large regions of the Nearctic and Neotropics usually involves the coexistence of a rich assemblage of native bees and introduced bees in the same agroecosystem. This ...
-
(Springer Verlag, 2017)© 2016, Springer-Verlag Berlin Heidelberg. The understanding of the spatial and temporal patterns in land use and land cover (LULC) change is a key issue for conservation efforts. In the Chilean hotspot, different studies ...

Native forest replacement by exotic plantations triggers changes in prey selection of mesocarnivores (Elsevier, 2015)Replacement of native forests by forest plantations may change the composition and abundance of small mammals, thus influencing the foraging behavior of mesocarnivores in these human-created habitats. We assessed how ...
