There is provided a sliding member formed by combining a resin overlay and a soft metal overlay. The sliding member has a soft layer comprising a metallic material with a hardness of less than 40 HV provided under a resin overlay layer comprising a solid lubricant and resin. In the event of contamination by a foreign matter, the soft layer under the resin overlay layer is capable of plastic deformation and the resin overlay layer is capable of partial deformation accompanying the plastic deformation due to the hardness (T1) (m) of the soft layer and the hardness (T2) (m) of the resin overlay layer being such that 0.2T1/T27.0 and 3.0T120.0. Consequently, a foreign matter is desirably embedded and resistance to a foreign matter can be improved. Low friction is maintained by the resin overlay layer even after contamination by a foreign matter.

Provided are a mixed metal halide perovskite compound, and an electronic device including the same, wherein the mixed metal halide perovskite compound includes an organic cation, two or more kinds of metal cations, and a halogen anion.

Undercooled liquid metallic core-shell particles, whose core is stable against solidification at ambient conditions, i.e. under near ambient temperature and pressure conditions, are used to join or repair metallic non-particulate components. The undercooled-shell particles in the form of nano-size or micro-size particles comprise an undercooled stable liquid metallic core encapsulated inside an outer shell, which can comprise an oxide or other stabilizer shell typically formed in-situ on the undercooled liquid metallic core. The shell is ruptured to release the liquid phase core material to join or repair a component(s).
