The pyrolysis of 5-HMF was investigated using density functional theory methods at B3LYP/6-31G++(d, p) level. Two possible pyrolytic pathways were proposed and
In order to study the effect of Zr on the microstructure and isothermal annealing performance of Cu–Cr in situ composites,Cu–15Cr and Cu–15Cr–0.24Zr alloys
This work deals with super-harmonic responses and the stabilities of a gear transmission system of a high-speed train under the stick-slip oscillation of the wh
