The larger problem of complexity allows us to set sequential exchange in its proper context.
Two different preparation methods were employed: simultaneous exchange of both metals, and a sequential exchange using the controlled surface reaction technique.
In his important article, Benito Arruñada draws out the significance of sequential exchange for property rights and traces inadequacies in the economics of property rights to its overly contractual focus, to the exclusion of multiple transactions on the same asset.
While complete cation exchange is a quite well developed method for the chemical transformation of binary NCs with preservation of their anion lattices via one-step or sequential exchange reactions, a partial exchange is an emerging technique which can yield a wide range of alloyed structures.
Tan, C.-S. et al. Sequential cation exchange generated superlattice nanowires forming multiple p n heterojunctions.
Luther, J. M., Zheng, H., Sadtler, B. & Alivisatos, A. P. Synthesis of PbS nanorods and other ionic nanocrystals of complex morphology by sequential cation exchange reactions.
We fabricated highly conductive and stable silver nanocrystal (Ag NC) thin film electrodes with tunable work functions using an all-solution-based method involving sequential ligand exchange and gold (Au) coating processes.
M2400 carrying in-frame deletions of sipA, sopA, sopE, sopE2, sopB, sptP, spvB, and spvC was generated by sequential allelic exchange in the chromosome of M712 [20] by using the suicide plasmids pM1315 (see below) and pM1664 (see below).
Therefore, we purified PEDF using sequential anion exchange chromatography.
Protein was purified by sequential ion exchange chromatography (MonoS 5/50 GL column, GE Healthcare, Chalfont St. Giles, UK) and calmodulin affinity chromatography (Calmodulin sepharose 4B, GE Healthcare).
Guanidine hydrochloride supernatant was dialyzed against urea buffer for 4 h and pooled with urea supernatant followed by a slow sequential buffer exchange to refolding buffer (50 mM Tris HCl, pH 7.5, 50 μM ZnO Ac 2, 5 mM DTT).
