Effect of pH variation on the subcritical crack growth parameters of glassy matrix ceramics
(2019-01-01)
The goals of our study were to calculate the subcritical crack growth (SCG) parameters of two veneering ceramics stored in water or Streptococcus mutans (S. mutans) biofilm and remineralizing medium, with indentation flaws. ...
Bioactive compounds extraction from malted quinoa using water-ethanol mixtures under subcritical conditions
(Elsevier Science, 2021-03)
The extraction of bioactive compounds from malted quinoa flour using different water/ethanol mixtures under subcritical conditions was performed, and two mathematical models to describe the extraction kinetics were compared. ...
Modelling of biomass fractionation in a lab-scale biorefinery: solubilization of hemicellulose and cellulose from holm oak wood using subcritical water
(Elsevier, 2015-09-26)
Lignocellulose fractionation is a key biorefinery process that need to be understood. In this work, a comprehensive study on hydrothermal-fractionation of holm oak in a semi-continuous system was conducted. The aim was to ...
