Summary: This paper summarizes the progress and challenges of using graphene-like materials in asphalt binder and asphalt mixture. Graphene-like materials can improve the performance of asphalt binder, but their effect on low temperature performance needs further research. The influence of graphene-like materials on the surface texture of aggregate in asphalt mixture also needs to be verified.

Summary: In this study, a V2O5 nanorods/GO nanocomposite was synthesized and used as an efficient photocatalyst for the degradation of VB dye under direct sunlight illumination, achieving almost complete degradation within 90 minutes. The excellent photocatalytic efficiency was attributed to the outstanding transfer of interfacial charge and the suppression of charge-carrier recombination. Kinetics of the degradation process was analyzed by calculating rate constants and half-life times, and a possible mechanism for the degradation process was discussed.

Summary: In this study, a 2D P/MnO2/r-GO nanosheet was synthesized and a composite with r-GO was made for the first time using Hummer's method. The material's structural, morphological, electrical, optical, and photocatalytic characteristics were investigated. The formation of a heterojunction between P/MnO2 and r-GO reduced the optical band gap energy, resulting in light absorption in the visible region. The P/MnO2/r-GO composite showed higher degradation efficiency for dyes compared to pure MnO2, and it also demonstrated stability and reusability in the photodegradation process.

Summary: This work presents a controllable, green, and facile strategy for preparing Au NRs@MnO2 core/shell nanosheets using the LSPR effect of gold nanorods. MnO2 is obtained through the reduction of KMnO4 with photoelectrons induced by the LSPR effect. Methanol is found to be significant in maintaining the shape of Au nanorods by acting as a hole scavenger, and the OER performance of the resulting Au NRs@MnO2 is notably enhanced under proper irradiation and stable after 1000 cycles.
