Summary: The photocatalytic property of a two-dimensional heterostructure MoS2/WS2 was investigated using first principles calculations. The energetic stability of different heterostructures was evaluated by comparing the combination energies, and the band gap of each heterostructure was calculated to determine its suitability for water splitting. Among the considered structures, the (MoS2)1/(WS2)1 heterostructure showed the most promising properties for overall water splitting, with a suitable band gap and energy barrier to prevent recombination and a low hydrogen desorption energy.

Summary: Cu-precipitation in reactor pressure vessel steels is a major concern for the degradation of mechanical properties. This study develops and implements a non-local phase-field model to investigate the equilibrium morphology of precipitates in the over-aged state. The model confirms that the precipitates should have an oblate lath-like shape, which is supported by experimental data. The orientation of the precipitates is consistent with literature. The mechanism of morphology accommodation is explained using the invariant-line method. However, the equilibrium values of elongation significantly deviate from experimental data, likely due to the metastable state of the precipitates during the coarsening process.

The microstructure and dynamic recrystallization mechanisms were analyzed using SEM and EBSD techniques. A strain-compensated Arrhenius constitutive equation and a PSO-BP ANN model based on machine learning were established to analyze the flow behavior. The experimental results showed that the flow stress decreased with increasing temperature and decreasing strain rate. The PSO-BP ANN model demonstrated good accuracy in predicting flow stress.
