The evolution of the film thickness in a grease lubricated rolling bearings is given by continuous process loss and replenishment oil track. It believed that long run, maintained bleeding from reservoirs. capabilities thus have an impact on and/or bearing life. ability to bleed changes during operation due mechanical ageing, which affects fiber structure grease. In this study lubricating consid...

BACKGROUND Polymer crosslinked aerogels are an attractive class of materials for future implant applications particularly as a biomaterial for the support of nerve growth. The low density and nano-porous structure of this material combined with large surface area, high mechanical strength, and tunable surface properties, make aerogels materials with a high potential in aiding repair of injuries...

The surfaces of hydraulic structures are vulnerable to damage and cracking, which can result in high-pressure reservoir water entering cracks endangering the safety structures. Therefore, it is necessary strengthen anti-seepage treatment protection on In this paper, we explore tensile high-water-pressure breakdown resistance properties polyurea coating material. To do so, independently designed...
