Entre la composición y el castigo. La actuación de las autoridades de la provincia de Buenos Aires frente a los robos cometidos por los indios amigos en la campaña (1832-1855)
This piece of work intends to show the impact produced by the «porteña» politics among the Indians, who we have already mentioned, giving special emphasis to the attempts taken to eliminating or reducing indian theft. Thus, the following pages, will show how two ways were found in order to conceive and solve one same problem. If the friendly indians associated theft with the damage caused to a member of a group by another one, and which therefore required reparation, the provincial authorities considered it an infringement of the law.El trabajo que presentamos se propone mostrar el impacto que tuvo la política porteña entre los indígenas a los que nos referimos atendiendo, especialmente, a los intentos de eliminar o regular los robos cometidos por aquellos. Así, estas páginas ponen en evidencia cómo se encontraron dos maneras de concebir y resolver un mismo problema. Si los indios amigos asociaban el robo a un daño que un miembro del grupo realizaba a otro y que, por lo tanto, requería de una reparación, las autoridades provinciales lo consideraban una infracción a la ley

TiO2 Nanostructures as Anode Materials for Li/Na-Ion Batteries
Here we summarize some results on the use of TiO nanostructures as anode materials for more efficient Li-ion (LIBs) and Na-ion (NIBs) batteries. LIBs are the leader to power portable electronic devices, and represent in the short-term the most adequate technology to power electrical vehicles, while NIBs hold promise for large storage of energy generated from renewable sources. Specifically, TiO an abundant, low cost, chemically stable and environmentally safe oxide represents in LIBs an alternative to graphite for applications in which safety is mandatory. For NIBs, TiO anodes (or more precisely negative electrodes) work at low voltage, assuring acceptable energy density values. Finally, assembling different TiO polymorphs in the form of nanostructures decreases diffusion distances, increases the number of contacts and offering additional sites for Na storage, helping to improve power efficiency. More specifically, in this contribution we highlighted our work on TiO anatase mesocrystals of colloidal size. These sophisticate materials; showing excellent textural properties, have remarkable electrochemical performance as anodes for Li/Na-ion batteries, with conventional alkyl carbonates electrolytes and safe electrolytes based on ionic liquids.Financial support through the projects MAT2014-54994-R
