Abstract: A coated composition for increasing adhesion between two surfaces that are in sliding, slipping, rolling-sliding or rolling-slipping contact with each other, the composition comprising: (a) a core, the core comprising one or more than one hard particle, each of the one or more than one hard particle having a Mohs hardness value of equal to or greater than 5, or a Vickers hardness of greater than or equal to 1000 and selected from the group of garnet, copper slag, silica sand, bauxite, Al2O3, staurolite, olivine, goethite, coal slag, MgO and Fe2O3, the core comprising about 70% to about 99.8% (wt/wt) of the composition; and (b) a coating over the core, the coating over the core comprising a resin and a conductivity additive, the resin comprising about 0.1% to about 20% (wt/wt) of the composition, and the conductivity additive comprising about 0.1% to about 10% (wt/wt) of the composition.

Abstract: A composition for increasing adhesion between two surfaces that are in traction, sliding or rolling-sliding contact with each other is provided. The composition comprises one or more than one first component, where each of the one or more than one first component has a Mohs hardness value of equal to or greater than 7, and one or more than one organic rheology additive. The one or more than one first component and the one or more than one organic rheology additive are present in a ratio from about 90:10 to about 99.9:0.1 (wt/wt). The composition does not comprise water. A method of increase adhesion between two steel surfaces in sliding-rolling contact is also described. The method involves applying the composition to the rail surface at a rate sufficient to increase the adhesion between the two steel surfaces.

Abstract: The present application relates to methods for the catalytic reduction of acid chlorides and/or imidoyl chlorides. The methods comprise reacting the acid chloride or imidoyl chloride with a silane reducing agent in the presence of a catalyst such as [Cp(Pri3P)Ru(NCMe)2]+[PF6]?.
