WitrynaThis provides a reason to believe that the nitrogen impurity occupying particular sites in SiC nanoclusters is an analog of the DX centers in the bulk crystal. In addition, the formation of the polaron-like states depends on the method of the surface passivation. In particular, the substitution of the Si–H surface bond with the Si–NH 3 one ... Witryna12 paź 2024 · Application of Ni Column Purification. Usually, competitive elution is used for eluting Ni column. First, wash off impure proteins and loosely bound proteins by imidazole with low concentration. Then, elute the target protein with suitable concentration. The elution order is relevant to the binding ability of proteins. Figure 3.
