In recent years, shale oil/gas has become increasingly important in global energy. The natural pores of are mainly micro-nano sizes and have the cross-scale characteristics, which makes traditional method difficult impractical studying seepage shale. order to obtain characteristics crack-pore-throat system, lattice Boltzmann dimensional analysis were used study an idealized crack-pore network. ...

an epoxy resin was modified by silica nanoparticles and cured with an anhydride. the particles with different batches of 12, 20, and 40 nm sizes were each distributed into the epoxy resin ultrasonically. electron microscopy images showed that the silica particles were well dispersed throughout the resin. tensile test results showed that young’s modulus and tensile strength increased with the vo...
