The GO nanosheet presents the apparent lamellar structure and their average sizes are in the range of 100–300 μm (Fig. 1a). The AFM image of GO indicates the results of less aggregation, and its thickness is about 1.48 nm (Fig. 1b), which is within the thickness range of the single-layer GO sheets [38]. Compared with … See more Figure 2 shows that the compressive tangent modulus of the PVA hydrogel is significantly enhanced by incorporation of GO. The compressive tangent modulus of … See more The indentation creep properties of PVA/GO hydrogels varied with GO contents are presented in Fig. 3. It indicates that the PVA/GO hydrogels deform fast … See more With the increase of GO content, the average friction coefficients gradually decrease for both migrating and stationary contact conditions during unidirectional sliding, … See more WebExploratory data analysis was carried out for the evaluation of tribological properties, and improvements were made to the modified surface wear resistance. The effects of another rare-earth metal, Cerium (Ce), were studied on the casting slab quality, microstructure and inclusions of cryogenic vessel steel in Wu et al.’s work [15].
