Bi- and Cu-substituted Ca3Co4O9 samples were prepared by conventional solid-state reaction method and the effect of element substitution on the microstructures
The characteristics and electrochemical properties of the layered Li(Ni_(1/3)Co_(1/3)Mn_(1/3))O_2 have been investigated by using the X-ray diffraction (XRD), s
We report a newly synthesized polymer of a star-shaped porphyrin compound(TPA-FxP) with four oligofluorene arms at its meso positions with the pronounced enhanc
