Summary: In addition to three-dimensional structures, polar semiconductor heterostructures are developing towards two-dimensional scale with mix-dimensional integration for novel properties and multifunctional applications. In this study, 2D Janus MoSSe and 3D wurtzite GaN polar semiconductors were stacked to form MoSSe/GaN polar heterostructures by polarity configurations. The polarity reversal of GaN in contact with Janus MoSSe and strain modulation were utilized to enhance the structural stability and tune the electronic energy band profiles of the heterostructures.

Summary: Advances in first principles methods are used to study the atom-vacancy exchanges near a screw dislocation in fcc Ni, revealing direction-dependent free energy profiles and temperature-dependent correlation effects. The dynamic approach shows intra-cell energy profile asymmetry related to dynamic geometry rearrangements. Despite absolute values of rate constants being similar, the HTST method generally underestimates rates by a factor of 2-5, partially explaining discrepancies between theoretical works and experiments in pipe diffusion diffusivities.

Summary: In this work, relativistic corrections to the electric field gradient (EFG) are presented, including spin-dependent corrections for the first time. The results show that these new corrections significantly improve the performance of the existing method and are in close agreement with calculations at the four-component Dirac-Hartree-Fock (4c-DHF) level. The accuracy of the EFG values obtained with this new method allows for the analysis of the electronic origin of relativistic effects using well-known nonrelativistic operators.

Summary: The study investigates the molecular level interaction of the spin-crossover (SCO) Fe-II((3,5-(CH3)(2)Pz)(3)BH)(2) complex with the Au(111) surface, revealing that adsorption on the metallic surface enhances transition energy and increases the relative stability of the low spin state, with a spin-dependent interaction stronger for low spin than high spin. The different strength of the Fe ligand field at low and high temperatures is reflected in the nature of states close to the Fermi level, with larger metal-ligand hybridization in the low spin state.

Summary: Systematic ab initio calculations were performed to investigate the factors affecting the diffusion properties of hydrogen in PdCu alloys. It was found that the diffusion barrier of hydrogen in BCC PdCu alloy is lower than that in FCC PdCu alloy. The interactions among interstitial hydrogen atoms are repulsive in BCC PdCu alloy, while they are attractive in FCC PdCu alloy. These results explain the weaker hydrogen penetration ability in FCC PdCu alloy compared to BCC PdCu alloy.

Summary: Droplet impact behavior on solid surfaces is crucial for industrial applications such as spray coating, food production, printing, and agriculture. The challenge lies in modifying and controlling the impact regime and contact time of the droplets, which becomes more critical for non-Newtonian liquids. This study explores the impact dynamics of non-Newtonian liquids on superhydrophobic surfaces and shows that the addition of Xanthan alters the shape and reduces the contact time of the droplets.
