Co valence transformation in isopolar LaCoO3/LaTiO3 perovskite heterostructures via interfacial engineering

Solvational Barriers to Interfacial Electron Transfer: Minimization via Valence Delocalization

Standard rate constants (k,) for interfacial electron transfer (ET) have been obtained for several redox couples featuring very small internal activation barriers. To render these ordinarily fast rates more easily measurable, we have employed low-defect-density, highly ordered pyrolytic graphite (HOPG) as an electrode material (see: Allred and McCreery, Anal. Chem. 1992,64,444). At the HOPG/aqu...

Strain engineering via amorphization and recrystallization in Si/Ge heterostructures

Chemical Synthesis and Characterization of Perovskite NdfeO3 Nanocrystals via a Co-Precipitation Method

A facile co-precipitation method for the synthesis of well-dispersed NdFeO3 nanocrystals is developed in the presence of octanoic acid as surfactant. Co-precipitation can produce fine, high-purity, stoichiometric particles of single and multicomponent metal oxides. The product is characterized by Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), scanning electron microsc...
