Wear particles in a hard disk drive may cause the head/disk interface to fail. We have experimentally investigated wear particle generation resulting from fretting wear between the dimple on the suspension and the gimbal spring. We have found that increasing the normal load as well as using a low friction coating reduces the formation of wear particles. INTRODUCTION Examination of failed hard d...

Zirconia has attracted considerable attention because of its diverse practical applications in fuel-cell technology, its use as a catalyst or catalyst support, its ability to combine with sulfuric acid to form extremely strong acids, and its use as an oxygen sensor and as a possible high-dielectric-constant material for large-scale integrated circuits or as a gate dielectric in metal-oxide semi...

The superresonance effect for a hollow dielectric sphere is numerically simulated with the Mie theory. It shown first time that weakly dissipative mesoscale spheres an air-filled cavity exhibit high-order Fano resonance related to internal modes. Superresonance in achieved by accurate choice of radius, while monolithic sphere, it ensured outer diameter particle under study. In this case, relati...
