Chemical separations play a vital role in refinery and reprocessing of critical materials, such
as platinum group metals, rare earths, and actinides. The choice of separation system─ …

Solvent extraction is used widely for chemical separations and environmental remediation.
Although the kinetics and efficiency of this process rely upon the formation of ion–extractant …

Effective and energy-efficient separation of precious and rare metals is very important for a
variety of advanced technologies. Liquid–liquid extraction (LLE) is a relatively less energy …

We study the adsorption of trivalent neodymium on floating arachidic acid films at the air–
water interface by two complementary surface specific probes, sum frequency generation …

Aqueous solutions of FeCl3 have been widely studied to shed light on a number of
processes from dissolution, mineralization, biology, electrocatalysis, corrosion, to microbial …

Graphene oxide is a promising, emerging separation material, as it is durable, dispersible in
water, and has naturally forming functional groups. Bulk studies using graphene oxide flakes …

The role of counterions in molecular recognition of lanthanides is underexplored, especially
when they exhibit weak interactions with the metal cations. Here, we report a complementary …

Understanding the chemistry of elements at the bottom of the periodic table is a challenging
goal in chemistry. Observing actinide species at interfaces by using interface-selective …

Graphene oxide (GO) membranes are excellent candidates for a range of separation
applications, including rare earth segregation and radionuclide decontamination …

Anions are expected to be repelled from negatively charged surfaces. At aqueous interfaces,
however, ion-specific effects can dominate over direct electrostatic interactions. Using …
