MoS 2 in particle sizes in the range of 1–100 μm is a common dry lubricant. [34] Few alternatives exist that confer high lubricity and stability at up to 350 °C in oxidizing environments. Sliding friction tests of MoS 2 using a pin on disc tester at low loads (0.1–2 N) give friction coefficient values of <0.1. [35] [36]
Molybdenite is a mineral of molybdenum disulfide, Mo S 2.Similar in appearance and feel to graphite, molybdenite has a lubricating effect that is a consequence of its layered structure.
An interstitial space is useful when the mechanical system of the building is highly sophisticated and changing the space on the primary floors is a distinct possibility. The heights of these spaces are generally 6 to 8 feet (1.8 to 2.4 m) and allow easy access for repair or alteration. [1]

In fact, empirically, it is found that neither of the above extremes is quite correct. The choice of metal does have some effect, and there appears to be a weak correlation between the metal work function and the barrier height, however the influence of the work function is only a fraction of that predicted by the Schottky-Mott rule.
