Methanogenic, Acidogenic and Hydrolytic activity tests of an anaerobic sludge of municipal wastewater plant
(IARAS, 2019)
The determination of methanogenic and non-methanogenic activity requires careful analysis because don’t exist a standardized method to find this bioindicator. Therefore, we wanted to evaluate and optimize this analytical ...

A Theoretical Study on the Inclusion of Fe, Cu, and Zn in Illite Clays
(Hindawi, 2019)
The inclusion of Fe, Cu, and Zn in (1, 0, 0), (0, 0.5, 0), and (0.5, 0.5, 0.5) sites of an illite with the KAl2Si4O12H2 structure has been studied. For the inclusion of the metals, their common oxidation states were chosen, ...

Cetane number prediction of waste cooking oil-derived biodiesel prior to transesterification reaction using near infrared spectroscopy
(Elsevier, 2019-03)
Fifty waste cooking oils (WCOs) were transesterified with methanol (1:8 WCO:methanol molar ratio) at 60 °C for 60 min using NaOH as catalyst (1% wt.). Fatty acid methyl ester (FAME) composition of the resulting biodiesels was ...
