SmFeTaO Photocatalyst for Degradation of Indigo Carmine Dye under Solar Light Irradiation por Torres Martínez, Leticia M., Ruiz Gómez, Miguel A., Figueroa Torres, Mayra Zyzlila, Juárez Ramírez, Isaías, Moctezuma, Edgar

“…The photocatalytic results showed that indigo carmine molecule can be degraded under solar light irradiation using the synthesized materials, sol-gel photocatalyst was 8 times more active than solid state. On the other hand, when Sm2FeTaO7 was impregnated with CuO as cocatalyst the photocatalytic activity was increased because CuO acts as electron trap decreasing electron-hole pair recombination rates.…”

Obtención y evaluación de péptidos bioactivos de recursos vegetales subutilizados con potencial agroalimentario por González Luna, Aldo Rodrigo

“…The results show that the protein hydrolysates obtained from the chia isolate showed the highest antioxidant activity (lower degree of discoloration of β-carotene, better reducing power and uptake of DPPH between 70-80%, compared to BHT). On the other hand, the peptides obtained using Alcalase in all three species showed a greater degree of inhibition of the angiotensin converting enzyme (ACE). …”

On aerodynamics of baseball pitches: reconstruction of spinning throws, and a lift force model for the knuckleball por Aguirre López, Mario Alberto

“…Dynamics of spinning balls is widely understood while only a few works about non-spinning balls are found in literature. On the other hand, there are some methods to reconstruct baseball trajectories, however, these methods do not usually deal with the movement equations, and if they do, its by knowing a lot of points of the real trajectory. …”

Co-Teaching: a successful factor on teacher training through collaborative practices and professional advice por Cortez Soto, Ana Berenice

“…According to the findings pre-service teachers realized they did not collaborate with cooperating teachers during planning, delivery and evaluation of the lessons. On the other hand, cooperating teachers were aware of the need of establishing collaborative teaching roles through a formal regulation that fosters commitment between participants. …”
