Open AccessApplication of benchtop humidity and temperature chamber in the measurement of water vapor sorption in US shales from Mancos, Marcellus, Eagle Ford and Wolfcamp formations
A benchtop humidity and temperature chamber was used to assess water vapor sorption in four US shale samples at 90 °C. Water sorption isotherms were measured at relative humidity ranging from 10 to 99% and tem...

Effect of pH on the stability of quartz in a multi-phase system of kaolinite, hydrous Al (hydr)oxide and quartz
The stability of quartz in a multi-phase system of kaolinite and Al (hydr)oxides and quartz has been addressed in quite a few studies. However, the impact of pH on these multi-mineral interactions has not been...
