Metal–organic frameworks (MOFs) containing V, Cr, Mn, Fe, Co, Ni, Cu, and Zr were pyrolyzed under nitrogen flow. The products of carbonized MOFs (CMOFs) contain metal oxides and carbonaceous residues, which were characterized by powder X‐ray diffraction (PXRD), electrical conductivity (EC), and Raman spectroscopy. To remove the metallic components in CMOFs, hydrofluoric acid (HF) treatment was performed...
As the spacing between the flying head/slider and the rotating disk in hard disk drives (HDDs) continues to decrease, some asperities on disk surface may lead to contacts and collisions between the magnetic head and disk, generating friction and wear which would then damage the working stability of HDD system. To investigate effect of disk surface asperity on static characteristics of air bearing...
