Journal ArticleDOI
Influence of feedstock source and pyrolysis temperature on biochar bulk and surface properties
Waled Suliman,James B. Harsh,Nehal I. Abu-Lail,Ann-Marie Fortuna,Ian Dallmeyer,Manuel Garcia-Perez +5 more
TL;DR: In this article, the mass fraction of volatiles, oxygen and the ratios of oxygen to carbon and hydrogen to carbon decreased linearly with pyrolysis temperature and the changes in surface charge were studied by ζ-potential measurements and were found to vary directly with the content of oxygenated functional groups.
Journal ArticleDOI
Comparison of different methods to measure contact angles of soil colloids
TL;DR: The differences in contact angles among the different methods were large and varied considerably: the most consistent contact angles were obtained for kaolinite with water, and illite with diiodomethane, and the thin-layer and column wicking methods were the least consistent methods.
Journal ArticleDOI
The mechanism of Zn2+ adsorption on calcite
TL;DR: In this article, the adsorption of Zn2+ on calcite (CaCO3(s)) was investigated from aqueous solutions in equilibrium with CaCO 3(s) and undersaturated with respect to Zn5(OH)6(CO3)2(s)).
Journal ArticleDOI
The role of biochar porosity and surface functionality in augmenting hydrologic properties of a sandy soil.
Waled Suliman,James B. Harsh,Nehal I. Abu-Lail,Ann-Marie Fortuna,Ian Dallmeyer,Manuel Garcia-Perez +5 more
TL;DR: The results indicated that the amount of oxygenated functional groups on the surface of biochars clearly differentiated the Biochar functionalities and porosity in terms of hydrophilicity, with the oxidized biochar being superior, followed by the low-temperatureBiochars, while the high temperature Biochars possessed lowest hydrophILicity.
