Ion Exchange Lithography: Localized Ion Exchange Reactions for Spatial Patterning of Perovskite Semiconductors and Insulators

Ion Exchange Reactions of Clays

I t has been recognized for many ypars that many aspects of clay technolofcy including soil treatment and drilling nnul treatment must remain in an essentially empirical state until a basis for the understanding of ion exchange reactions is established. Much of the work on ion exchange reactions of clays in the i)ast has been directed toward establishing total exchange capacities or determining...

X-ray Lithography on Perovskite Nanocrystals Films: From Patterning with Anion-Exchange Reactions to Enhanced Stability in Air and Water

Films of colloidal CsPbX3 (X = I, Br or Cl) nanocrystals, prepared by solution drop-casting or spin-coating on a silicon substrate, were exposed to a low flux of X-rays from an X-ray photoelectron spectrometer source, causing intermolecular C═C bonding of the organic ligands that coat the surface of the nanocrystals. This transformation of the ligand shell resulted in a greater stability of the...

Ion-Exchange Reactions for Two-Dimensional Quantum Antiferromagnetism

Ion-exchange reactions between cartilage and various cations.

Ion exchange membranes and separation processes with chemical reactions

Recent research trends in the development of ion exchange membranes and their use in separation processes with chemical reactions are reviewed. Emphasis in research on the ion exchange membrane is trending toward analysis of micro-structure of the membranes and to development of new functionalized ion exchange membranes in response to industrial requirements. Separation processes with chemical ...
