This study presents electrochemical performance loss and correlated material degradation of an electrocatalyst, nitrogen-doped graphene integrated with a metal–organic framework (N-G/MOF), by the effect of H 2 O 2 -derived oxidative species.
The isotopic distribution of the production cross sections of $^{136}$Xe on proton and carbon at 168 MeV/u were obtained in inverse kinematics technique at RIKEN Radioactive Isotope Beam Factory. The target dependence at 168 MeV/u was investigated systematically. The cross sections measured in the present work are compared with the previous results obtained at different reaction energies to investigate the energy dependence for the reactions on proton. The experimental results on proton are compared with the PHITS calculations including both the cascade and evaporation processes for the model bench-marking.
Aiming to improve the thermal characteristics of modern electronics, we experimentally study the performance of a stainless steel/water loop heat pipe(LHP) under natural cooling condition. The LHP heat transfer performance, including start-up performance, temperature oscillation and total thermal resistance at different heat loads and with different incline angles have been investigated systematically. Experimental results show that at an optimal heat load(i.e. 60 W) and with the LHP being inclined 60 to the horizontal plane, the total thermal resistance is lowered to be ~0.24 K/W, and the temperature of evaporator could be controlled steadily at around 90 C.
