“…The effect of GO on the mechanical state of CEA was evaluated by the glass transition temperature ( T g ), which is the temperature at the peak value of the tan δ ‐temperature curve. [ 3 ] The introduction of GO lowered the T g of CEA from 51.4°C to 47.1°C (Figure 11, Table 4). For GO/CEA0.1, there were two peaks in its tan δ ‐temperature curve, corresponding to two T g s (47.1°C and 70.2°C).…”

“…[2] CEA is emerging due to its energy-saving, environmentalfriendly, and desirable engineering performance. [3] CEA aged during its service life, and its performance especially the toughness degraded when exposed to ultraviolet (UV) radiation, thermal oxidation (TO), and other aggressive conditions, which is unfavorable for road safety and comfort.

As a green material for high‐performance paving, cold‐mixed epoxy asphalt (CEA) should be improved in compatibility, mechanical performance, and thermal stability. This work is going to estimate the potential of graphene oxide (GO) as an additive for preparing GO/CEA composites with different GO content from 0 to 0.2 wt%. The influences of GO on the structure and performances of CEA were evaluated by Fourier transform‐infrared spectrum, fluorescence microscopy, viscosity, thermogravimetric analysis, tensile test, and dynamic mechanical analysis. Results showed that the functional groups on GO reacted with CEA and improved the compatibility of epoxy resin and asphalt. The viscosity of the GO/CEA composites increased slightly and the pot life decreased significantly, with GO loading increasing. The cured GO/CEA composite with 0.1 wt% GO had the best heat resistance and showed a gentle thermal decomposition. GO improved the toughness of the cured CEA and had a certain weakening effect on its strength. The introduction of GO lowered the glass transition temperature of the cured CEA from 51.4 to 47.1 °C and decreased its storage modulus. The preliminary exploration of this study shows that the modification of GO for CEA is feasible, and it is expected to prolong the service life of CEA.

“…In comparison with diesel, 1,2-dichloropropane, trichloroethylene, and solvent naphtha, FAME was recommended for use as an asphalt solvent. 72 Fatty acid methyl ester has also been evaluated for use in solvent extraction. As high VOC solvents are among the most used materials for solvent extraction purposes, green alternatives are of potential value.…”

For the past two decades, biodiesel has been the workhorse for pioneering green fuel alternatives to petroleum diesel. Recent advancements in decarboxylation of fatty acid feedstocks through hydrogen treatment or the use of fatty acid photo decarboxylase have led to increasing interest in renewable diesel as the next ‘state of the art’. This paradigm shift has caused concern among traditional biodiesel producers, whose infrastructure may not be suitable for renewable diesel, that the supply chain and market demand for biodiesel will be disrupted. However, there are numerous alternative (non‐fuel) uses for biodiesel, which has applications in solvents, lubricants, feedstock chemicals, and more. This review seeks to highlight the advantages of using biodiesel in these industries and the potential for further research and development. © 2022 Society of Chemical Industry and John Wiley & Sons, Ltd.
