Ni-xNiO-NiFe_2O_4 cermets with different NiO contents were prepared and the corrosion behaviour in Na_3AlF_6-Al_2O_3 melts was investigated in laboratory electr
A novel topological index W F is defined by the matrices X,W and L as W F=XWL.The topological index WF based on the distance-related matrix of molecular graph
The crystal and molecular structures of [(C 3H 7O) 2PS 2] 2(CCDC No.217201) were determined by means of X-ray crystallography. It crystallized in a triclin
