Electron Spin Dynamics of the Superconductor CaC6 probed by ESR [PDF]
, 2007 Conduction Electron Spin Resonance (CESR) was measured on a thick slab of CaC6 in the normal and superconducting state. A surprising increase of the CESR intensity below Tc can not be explained by the theoretically predicted change in spin susceptibility.

Film thickness in a ball-on-disc contact lubricated with greases, bleed oils and base oils [PDF]
, 2012 Three different lubricating greases and their bleed and base oils were compared in terms of film thickness in a ball-on-disc test rig through optical interferometry. The theoretical values calculated according to Hamrock's equation are in close agreement

Phase transition of lithium soap greases.
Journal of The Japan Petroleum Institute, 1986 The phase transition of lithium soap grease by differential thermal analysis (DTA) is described in this review paper. The phase transition temperature of lithium soap and its grease change as a function of the molecular weight of the soap. The transition temperature of grease and the structure of soap micelles formed in it are significantly affected by
