DOWNWELL: Preproducción, escenarios y animación de un teaser.

[ES] El objetivo de este proyecto es hacer un teaser animado para DOWNWELL, una serie de animación 2D todavía en desarrollo. Este trabajo recoge tanto el trabajo en diseño de personajes y escenarios como el desarrollo de una estética única y sombría que esperamos atraiga la atención del público.[EN] The aim for this proyect is to make an animated teaser for DOWNWELL, a 2D animation series currently in pre-production. This document brings together the work of the characters and environment¿s design besides the development of a unique and gloomy aesthetic we hope is enough to attract viewer's attention.Cruceira Modesto, Á.

Influence of gold nanoparticles size for photocatalytic NO oxidation in low loading Au/TiO2 catalysts

Gold nanoparticles (AuNPs) supported on TiO2 are one of the most investigated photocat-alysts, however, the positive effect of AuNPs size reduction on Au/TiO2 activity is clear for conventional catalysis, but this relationship not strictly happens in photocatalysis. The present work investigates how small changes in the lower size range of AuNPs can affect the Au/TiO2 photoactivity in order to maximize the performance of photocatalysts with low metal loadings (<1 wt%). Precipitation-deposition methods and a speciation-controlled incipient wetness impregnation (ScIWI) method have been employed for preparing Au/TiO2 photocatalysts that exhibited a NOx elimination capacity significantly higher than pristine TiO2. Comparing the photocatalysts, ScIWI method achieved the highest gold dispersion and Au-TiO2 contact perimeter providing the most active photocatalysts, confirming the positive effect of AuNPs size reduction in the average sizes around 2 nm. In addition, on the basis of the results obtained, it has been proposed that the adsorption of nitrogen oxides species on gold has a relevant role on the NO photooxidation process.(c) 2023 The Author(s).
