Gold-iron oxide nano-heterostructures with a clear and well-defined morphology were prepared via a seed-assisted method. The synthesis process and the events of heterogeneous nucleation during the decomposition of the iron precursor were carefully studied in order to understand the mechanism of the reaction and to tailor the architecture of the fabricated heterostructures. When employing Au seeds of 3 and 5 nm, nanoparticles with a dimer-like morphology were produced due to the occurrence of a single iron oxide nucleation event. Otherwise, multi-nucleation events could be favored by two mechanisms:(i) by the incorporation of a reducing agent and the slowing down of the heating protocol, leading to a core-shell system;(ii) by the increase of the Au seed size to 8 nm, leading to a flower-like system. Further increase of the Au seed size to 12 nm using similar synthesis conditions promotes the homogeneous nucleation and growth of the iron oxide phase, without formation of heterostructures. An in-depth study was performed on the gold-iron oxide heterostructures to confirm the epitaxial growth of the oxide domain over the Au seed and to analyze the elemental distribution of the components within the heterostructures. Finally, it was found that the modification of the plasmonic properties of the Au nanoparticles are strongly influenced by the architecture of the heterostructure, with a more pronounced damping effect for the systems produced after multi-nucleation events.

Cocoa (Theobroma cacao), in all its presentations, is consumed all over the world and is one of the main drivers of the economic in several countries. The world’s Cocoa tendency is focused on developing special beans. This category is subject to postharvest processes of utmost importance such as the fermentation and dry, which are currently carried out with traditional and poorly effective devices, which need to be improved to obtain a high quality product. The aim of this study was to evaluate the influence of the pectin lyase enzyme (E.C.4.***.2.10) on the postharvest cocoa process. We evaluated the enzyme dosage (1.0% and 0.5%) in fermentation and its effect on the variables temperature, acidity and drying time by convection at 60°C. The Pectin lyase activity during fermentation does not cause a significant effect on the variables of temperature and acidity;however, the drying process time required to achieve 7.0% moisture was reduced. The enzyme dosage of 1.0% was the best result, the amount of exudate obtained (115 ml) during fermentation and the best degree of fermentation (77% ± 3.8) were increased and further shows a change in porosity facilitating the scale surface and internal moisture diffusion. The drying rate (Nw) expressed in kgwater/m2 * min was determined based on the empirical model of Newton, where the higher speed was obtained during the falling period. In conclusion, enzyme dosage 1% was the best concentration evaluated because weaken grain husk, which allowed an adequate fermentation,and subsequent time drying reduction until 10.8 h.

The environmental protection of tropical marine and coastal areas faces different challenges due to the diversity of aspects related to these areas, which include natural, social and economical issues. Despite these challenges, efforts for the protection of these areas are urgent nowadays because of the dramatical increase of human related threats like habitat destruction and population growth. malaga Bay (mB) is a tectonic estuarine system located in Panama Bight (central region of the Colombian Pacific coast), which due to its origin shows important environmental characteristics of few sites in the Tropical Eastern Pacific (TEP) match. For these reasons, the government of Colombia declared in 2010, the bay’s marine area as a marine National Natural Park in order to preserve its unique estuarine marine biodiversity. Despite this measure, mB presents several conditions that make environmental protection a very difficult task. In this paper, we present the geographical context, biodiversity and natural resources, environmental threats, the complexity of economic and social context, and the institutional and legal context of mB, to exemplify the difficulty that the protection of marine areas face in the TEP.
