Selenate and selenite oxyanions are crystallized together with sulfate anions using ligands. In this approach, we will take advantage of the tendency of these similar oxyanions to co-precipitate into crystalline solid solutions.
The invention is a material that will selectively absorb lithium from process waters, and then in a subsequent step, allow the lithium to be released and concentrated; allowing efficient lithium extraction from fluids for use as commodity chemicals.
A novel molecular sorbent system for low energy CO2 regeneration is developed by employing CO2-responsive molecules and salt in aqueous media where a precipitating CO2--salt fractal network is formed, resulting in solid-phase formation and sedimentation.
Low-Temperature Electrochemical Conversion of Carbon Dioxide into Graphite in Molten Carbonate Salts
The capture and conversion of atmospheric carbon dioxide (CO2) into non-volatile value-added solid carbon products is an urgent need to address the deleterious effects of the rising level of atmospheric CO2.
Current fuel used in nuclear light water reactors that generate energy for the grid use a solid form of uranium that is heated and processed to form pellets.
Efficient CO2 capture using deep eutectic solvents with modular, scalable membrane contactors.
The technology provides highly fluorinated nanoporous molecular sieve membranes for efficient CO2 separation.

The widespread use of inexpensive salt hydrate-based phase change materials, or PCMs, has been prevented by a key technical challenge: phase separation, also known as incongruency, which results in the significant degradation of the materials' ability to store thermal energy o
