Over the past seven years, chemical vapor deposition has emerged as the preferred technique for the synthesis of graphene films on metal as well as other substrates. Commercial cell phones with a graphene touch screen have been introduced and roll-to-roll production tools have been demonstrated. The deposition temperature is also reduced from(More)
Joints often have important effects on seepage and elastic properties of jointed rock mass and therefore on the rock slope stability. In the present paper, a model for discrete jointed network is established using contact-free measurement technique and geometrical statistic method. A coupled mathematical model for characterizing anisotropic permeability(More)
