Artificial neural network modeling of phenol adsorption onto barley husks activated carbon in an airlift reactor
Publicado 2013“…Moreover, activated carbons from BH obtained at the optimal conditions mainly developed a porous vstructure (mesopores > 71% and micropores > 28%), achieving a high surface area (811.44 m2 g-1 ) that is similar to commercial activated carbons and lignocellulosic-based activated carbons. These results imply that the pore width and surface area are large enough to allow the diffusion and adsorption of pollutants inside the adsorbent particles. …”

A global-scale screening of non-native aquatic organisms to identify potentially invasive species under current and future climate conditions
Publicado 2021“…The risk thresholds determined for taxonomic groups and climate zones provide a basis against which area-specific or climate-based calibrated thresholds may be interpreted. In turn, the risk rankings help decision-makers identify which species require an immediate ‘rapid’ management action (e.g. …”

Growth, feed intake, survival, and histological response of white shrimp Litopenaeus vannamei fed diets containing grains naturally contaminated with aflatoxin = Crecimiento, consu...
Publicado 2012“…It is worth noting that shrimp fed 40 g kg–1 TA presented a high hepatopancreatocyte sloughing coefficient. Based on these results we conclude that the presence of aflatoxins, even at low levels, reduces feed intake and weight gain, and alters the cells of the hepatopancreas. …”

Procesamiento y estudio preliminar de un material compuesto de matriz AlSi₁₀Mg reforzado con nanopartículas de Ti mediante aleado mecánico.
Publicado 2020“…The results of the Vickers hardness show that with the addition of the nano particles and with the sintered one, it decreases; on the other hand, through the SEM and DRX the creation of new phases such as magnesium oxide and titanium oxide was observed in addition to observing some pores in certain microstructures. Based on the results obtained, with the addition of the NPTsTi to the aluminum alloy and without these, the wear resistance is not affected by the addition of these, while the hardness decreases when the titanium nano particles are added and with the sintering process due to the saturation that was presented in the material by the titanium nano particles.…”
