Abstract: Provided are diamondoid salts, electrolytes comprising the diamondoid salts, and electrochemical devices incorporating the diamondoid salts or electrolytes. In embodiments, an electrolyte for an electrochemical device comprises a metallic salt and a diamondoid salt, the diamondoid salt comprising a diamondoid-functionalized cationic core and a counter anion, the diamondoid-functionalized cationic core comprising a cationic core and a diamondoid group covalently bound to the cationic core.

Abstract: A system and method for determining and controlling a speed of a conveyor belt configured for transferring material from a source of the material to a haul vehicle includes a motor and associated head pulley shaft operatively coupled to a conveyor belt head pulley configured for driving the conveyor belt. The motor is connected to a conveyor belt tensioner block configured to enable adjustment of a tension in the conveyor belt, and the head pulley shaft is rotatably supported within the conveyor belt tensioner block. A speed ring gear is mounted on the head pulley shaft and located at least partially within a bore through the conveyor belt tensioner block. A speed sensor is mounted on the conveyor belt tensioner block in a position radially outward from teeth of the speed ring gear as the speed ring gear and head pulley shaft rotate within the bore through the belt tensioner block.

Abstract: Disclosed is a boot construction utilizing both exotic and non-exotic leathers in a multi-part vamp. This construction provides increased durability, more efficient material utilization, and aesthetic appeal. More specifically, the vamp includes a forward toe portion constructed primarily from an exotic leather and a rearward saddle portion constructed from a non-exotic leather. The saddle portion further includes a cutout that exposes an underlying portion of another leather material.
