Metal precursor for nanoparticle synthesis
Case I: Metal acetylacetonate Example 1: Nickel First, the Ni±oleylamine complexwas prepared by reacting 0.52 g of nickel(acetylacetonate)2[Ni(acac)2, Aldrich Chemical Co., 95%] and 2 mL of oleyla-mine (Aldrich Chemical Co., technical grade, 80%) at 100Cunder an Ar atmosphere. The resulting metal-complex solu-tion was injected into 5 g of triphenylphosphine (TPP, AldrichChemical Co., 99%) at 215C.…

Cyclic voltammetry – Charge-Discharge
Case 1: Cobalt oxide in Li-Battery Figure 1. Electrochemical properties of the multi-shelled cobalt oxide yolk–shell powders post-treated at various temperatures: (a) Initial discharge and charge curves, (b) and (c) CV curves, and (d) cycling performances.[Nano Research 2014, 7(12): 1738–1748] Figures 6(b) and 6(c) show the cyclic voltammograms (CVs) of the two samples post-treated at…

TEM Characterization
Case 1: Antiferromagnetic Cobalt Oxide Nanooctahedra The organic−inorganic interface determines the crystalline growth directions of the nanoparticles by means of a dynamic solvation of these surfactants in solution, which generally contain electron-donating groups to allow coordination to electron-poor metal atoms at the nanocrystal surface. Nano Lett. 2014, 14, 2, 640–647 Figure 1. EEL spectra (h)…
