Origin of the inhomogeneous nanoscale resistivity in chromium doped V2O3
All Cr:V2O3 films were deposited using reactive radio-frequency (RF) magnetron sputter deposition from metallic targets in an oxygen containing atmosphere. The targets used were either pure vanadium or a vanadium/chromium alloy containing 15% Cr….

The effect of axial geometrical variations on the steady state characteristics of oil lubricated journal bearings using titanium dioxide nanoparticles as lubricant additives
Formulation
Figure 1 depicts the bearing arrangement and the suggested curvilinear coordinate system. When the Reynolds number is low, the fluid inertia forces may be ignored compared to the viscous forces, as is always the case with bearing…
