Abstract: One or more techniques and/or systems are disclosed for a dry-type lubricant for use in a dry product hopper to help improve dry product flow and to improve anti-jamming properties of the dry product. The example lubricant can comprise a hydrophilic fiber, such as cellulose, having a width to length aspect ratio that provides a thin fiber. A plurality of hydrophobic particles are deposited on the surface of the fiber, resulting in a fiber surface exhibiting amphiphobic properties. Further, the fiber can operably absorb water, and then releases the absorbed water to the surface of the fiber under mechanical stress, such as when mixed with a product in a hopper. This can result in the water being disposed on the surface of the fiber, to provide lubrication to a product in a hopper to improve flow and anti-jamming characteristics of the product in the hopper.

Abstract: Compositions and methods are provided that are beneficial for use in downhole applications, especially oil and gas well bores. A composition includes an elastomer doped with a dopant. The presence of the dopant increases a rate of microbial degradation of the elastomer by a microbe. A method includes forming an article including a doped polymer. The doped polymer includes an elastomer doped with a dopant. The method also includes placing the article in a service environment. The presence of the dopant in the doped polymer increases a rate of microbial degradation of the elastomer by a microbe in the service environment.
