The analysis of hydrogen-producing nature was presented through the point of catalysis of hydrogenase, the production of energy and its transportation. From author's view, the course of de-hydrogen from pyruvic acid to acetyl-CoA was the chief determinant for hydrogen producing. And the balance and adjustment of NADH/NAD〓 was just the necessary condition, not the foundation reason.

Due to their applications in magnetic, optical, electronic and catalyst, polynuclear lanthanide clusters are of importance. In this part, a series of nanowheel-shaped nonanuclear lanthanide clusters,〓〓(Ln=Sm~Tm; BA=benzoylacetone), were prepared and characterized. Each complex can exist in three phases, i. e., cubic, tetragonal and triclinic.
