/graphene nanohybrids reaches 650 mA·h/g, almost twice that of commercial graphite anode, demonstrating the high lithium storage capability and the excellent cycling behavior of the sample. Fig. 3 XPS... nanoparticles with average diameter of 3-5 nm homogeneously adhered to the surfaces of graphene via a ultrasonic method. 2) The as-prepared CoO/graphene nanohybrids were used as anode materials for lithium......
gas flows are investigated by immersion and wear experiments.The results show that the bubbles of CO2 into water severely destroy the cross-linking network of rubber and form defects on the surface... in water.The bubbles of CO2 decrease the steady frictional coefficient of rubber in water due to the presence of the gas in water lubricant film.The steady frictional coefficient in water with different......
