Photocatalytic hydrogen production by biomimetic indium sulfide using Mimosa pudica leaves as template por Carrasco Jaim, Omar Ali, Ahumada Lazo, Rubén, Clark, Pip C.J., Gómez Solís, Christian, Fairclough, Simon M., Haigh, Sarah J., Leontiadou, Marina A., Handrup, Karsten, Torres Martínez, Leticia Myriam, Flavell, Wendy R.

“…Biomimetic indium sulfide also showed significant amounts of Fe introduced as a contaminant present on the Mimosa pudica leaves. The presence of these sulfur and iron species favors the photocatalytic activity for hydrogen production by their acting as a sacrificial reagent and promoting water oxidation on the surface of the templated particles, respectively. …”

Empleo de xerogeles orgánicos de carbono en la remoción de clorfenamina mediante foto Fenton-like solar por Mar Ortiz, Alondra Fabiola

“…La caracterización del material reveló la inserción de complejos de Fe(III) enlazado a grupos oxigenados del tipo carboxílicos que promueven la activación del material con radiación visible, lo que lo convierte en un material viable para la oxidación de contaminantes presentes en fase acuosa. El estudio cinético reveló que las constantes cinéticas de degradación fueron 9.34×10- 1 min-1 , 1.78×10-1 min-1 y 51.7×10-1 min-1 para los procesos FFLH, fotocatalítico y fotolítico respectivamente. …”

Ultraviolet Radiation Effect on Seed Germination and Seedling Growth of Common Species from Northeastern Mexico por Foroughbakhch Pournavab, Rahim, Bacópulos Mejía, Elly, Benavides Mendoza, Adalberto, Salas Cruz, Lidia Rosaura, Ngangyo Heya, Maginot

“…Accurate handling of the ultraviolet light that reaches the crops allows the improvement of different aspects of production, such as the shape and color of the plants, the precocity of the crops, and an improvement in the control of pests and diseases. The present study was carried out with the purpose of studying the responses in terms of germination and growth of four plant species—Glycine max, Triticum aestivum, Helianthus annuus, and Pinus maximartinezii—exposed to different doses of UV-C and UV-B radiation, for evaluation through the standard germination and accelerated aging tests, registering the germination rate (GR) and vigor (V), the number of normal seedlings (NS), and the average lengths of radicle (ALR) and plumule (ALP). …”
