( American Chemical Society , 2015 , Article)Two CO2 solid sorbents based on polyethylenimine, PEI (Mn ∼ 423 and 10K), impregnated into mesoporous silica (MPS) foam prepared in kilogram quantities via a scale-up process were synthesized and systematically characterized ... -
CO2 transportation safety regulations and energy requirement
( Elsevier , 2022 , Book chapter)Carbon dioxide transportation from the capture point to the utilization or storage point plays a key function in carbon capture and storage systems. CO2 transportation modes (onshore pipelines, offshore pipelines, and ... -
Co2+ substituted for Bi3+ in BiVO4 and its enhanced photocatalytic activity under visible LED light irradiation
( Royal Society of Chemistry , 2019 , Article)We investigated the fabrication of Co-doped BiVO4 (Bi1-xCoxVO4+δ, 0.05 < x < 0.5) by the substitution of Co ions for Bi sites in BiVO4. The X-ray diffraction (XRD), Raman, and X-ray photoelectron spectroscopy (XPS) results ... -
CO<inf>2</inf> solubility in aqueous potassium lysinate solutions at absorber conditions
( Academic Press , 2017 , Article)In this work, CO2 solubility in aqueous potassium lysinate solutions has been measured for the concentrations of (1.25–3.28) mol·kg−1 and at temperatures of (313–343) K. The vapour-liquid equilibrium data were correlated ... -
COACT: a query interface language for collaborative databases
( Springer New York LLC , 2018 , Article)Data curation activities in collaborative databases mandate that collaborators interact until they converge and agree on the content of their data. In a previous work, we presented a cloud-based collaborative database ... -
