Corrosion inhibitive properties and adsorption behaviour of ethanol extract of Piper guinensis as a green corrosion inhibitor for mild steel in H2SO4

The corrosion inhibition of mild steel by ethanol extract of Piper guinensis (EEPG) has been studied using gravimetric, gasometric and thermometric methods. The results of the study reveals that the different concentrations of ethanol extract ofPiper guinensis (EEPG) inhibit mild steel corrosion. Inhibition efficiency of the extract is found to vary with concentration, temperature and period of immersion....

Modeling and theoretical calculation of liquid heat capacity of alcohols and aldehydes using QSPR

The most important domain part of chemometrics is the studies which relate the properties of molecules to their structural characteristics. In this work we use the quantitative structure – property relationship (QSPR) for providing a linear model for predicting the heat capacity of alcohols and aldehydes in liquid phase at 298 K. To perform this research, a set of 32 alcohol and aldehyde as data series was...
