Obtaining Porous Zinc Oxide Ceramics Using Replica Technique: Application in Ph...
Faria,Felipe P.; Ruellas,Thamara M. O.; Roveri,Carolina Del; Malafatti,João Otávio Donizette; Paris,Elaine Cristina; Giraldi,Tânia R.This research investigated the production of porous zinc oxide (ZnO) ceramics obtained by the replica method for water depollution by photocatalytic processes. Five photo-decolorization cycles were performed to analyze the reuse potential of the ceramics. Statistical analyses using R programming were conducted to investigate possible significant differences between them. The ceramics porosities were between 46....
Avaliação do potencial de uso da hidroxiapatita para fertilização de solos
Oliveira,Milene Aparecida Rodrigues de; Paris,Elaine Cristina; Ribeiro,CauePlants absorb phosphorus from the soil, which has low levels of this element due to the poor solubility of these compounds in soil and high adsorption capacity of the element by soil particles. Therefore, the purpose of this study was to assess, using hydroxyapatite nanoparticles synthesized in the laboratory, the amount of phosphorus available under different conditions. The results showed that the phosphorus ...
