Riaño Castañeda, John (author)The increasing levels of carbon dioxide (CO2) emissions in the atmosphere are significantly contributing to climate change. One approach to mitigate this issue is through Carbon Capture and Storage (CCS) techniques, which involve storing CO2 emissions underground. Depleted reservoirs are a potential option for subsurface CO2 storage. However, a...master thesis 2023

Zhang, Y. (author), Chen, Y. (author), Copuroglu, Oguzhan (author)This paper presents the influence of P<sub>2</sub>O<sub>5</sub> incorporated in slag on the hydration characteristics of cement-slag system. It was found that the gradual addition of phosphorus oxide in slag did not change overall mineralogy of the hydration products. Except hydration retardation in the dormant stage, chemically bound water...journal article 2023

Wang, Xiaoda (author), Zhao, Yuqing (author), Han, Lumin (author), Li, Ling (author), Kiss, A.A. (author)Cylcohexanol is an essential bulk chemical that can be produced via cyclohexene hydration, a liquid-liquid two-phase reaction that is limited by the low reaction rate and the equilibrium conversion. Adding an appropriate solvent is the most promising method to break through these limitations. However, in previous works the solvent was almost...journal article 2023
