Supercritical Fluid Chromatography of Ionic Compounds
… polar solvent (i.e. modifier) which contains an ionic component (i.e. additive) to a CO2 mobile phase has shown major improvement in the elution of ionic analytes via packed column supercritical fluid chromatography (SFC). Firstly, we focused on the elution of sodium arylsulfonate analytes by …

Ion Transport in Chloroplasts with Role in Regulation of Photosynthesis
… photosynthetic organisms grow contains numerous ionic compounds. These compounds are taken up and used in numerous important processes, including photosynthesis in chloroplasts. As in the rest of the cell, specialized proteins named channels and transporters mediate ion transport across membranes …

Preparation and characterisation of mixed CeO2-Nb2O5-Bi2O3 nanoparticles
Mixed metal oxides are ionic compounds containing at least two metal ions within an oxide structure. The literature contains a plethora of examples of mixed metal oxides on the bulk scale, which have been well characterised, however, mixed metal oxides on the nanoscale are far less well understood. …

Interactions of ionic liquids with uranium and its implications on biotransformation
Room temperature ionic liquids (ILs) are pure ionic compounds with melting points below 100 C, which have drawn great attention due to their many unique properties. They have been widely used in organic synthesis, analytical chemistry, and biochemistry. Although ionic liquids have been used to …
