Reactivity of micas and cap-rock in wet supercritical CO2 with SO2 and O2 at CO2 storage conditions

Normalizing cerebrovascular reactivity map via concomitant CO2 and O2 challenge

INTRODUCTION: Cerebrovascular reactivity (CVR), referring to the ability of blood vessels to dilate upon stimulation, is an important marker of brain’s vascular function (1). During the past few years, there has been a surging interest in quantitative mapping of CVR using BOLD MRI in combination with hypercapnia challenge (2-5) and to use this technique in cerebrovascular diseases (3,4) and nor...

Ionic Liquids and Supercritical CO2

Ionic liquids (ILs) are organic salts that have melting points around room temperature. They have received tremendous attention recently due to their low volatility and subsequent potential to reduce air pollution if used as replacements for volatile organic solvents. As a result, they have the potential to be used in a wide variety of chemical processing applications, including as solvents for...
