Growth and properties of lead iodide thin films by spin coating por Acuña Leal, Daniel Arturo, Krishnan, Bindu, Shaji, Sadasivan, Sepúlveda, S., Menchca, J. L.

“…In this study, lead iodide (PbI2) thin films were deposited on glass substrates by spin coating a solution of 0.2 M PbI2 dissolved in dimethylformamide, varying the deposition time and the spin speed. The thickness of the thin films decreased with increase in spin speed and deposition time, as examined by profilometry measurements. …”

Phenol adsorption onto coffee waste - granular activated carbon: kinetics and equilibrium studies in aqueous solutions por Díaz de León Garza, María de la Luz, Soto Regalado, Eduardo, Loredo Cancino, Margarita, Cerino Córdova, Felipe de Jesús, García Reyes, Refugio Bernardo, Dávila Guzmán, Nancy Elizabeth, Loredo Medrano, José Ángel

“…abstract In this research, the production of granular activated carbon from coffee waste (CW) by chemical activation with zinc chloride was studied by using a 23 factorial design with the three responses (surface area, yield, and hardness) and studying three factors (the activation temperature, activation time, and impregnation ratio). The findings expose that after the experimental design, the highest response values were achieved at an activation temperature of 600°C, an activation time of 40 min, and an impregnation ratio of 1.5 g ZnCl2 g–1 CW. …”
