In this study, we explore the potential of graph neural networks (GNNs), in combination with transfer learning, for the prediction of molecular solubility, a crucial property in drug discovery and materials science. Our approach begins with the development of a GNN-based model to predict the dipole moment of molecules.

In this work, we employ Moiré lattices generated in a high-order nonlinear material to investigate the existence of topological solitons under diverse geometries, which are controlled by the twisting angle of sublattices. The formation of solitons in both commensurate and incommensurate Moiré lattice configurations allows us to explore deeper into the impact of geometric transitions on soliton stability and localization.

The auxiliary parts of the impact test hammer are only suitable for certain cases. The impact velocity of other cases are determined by measuring. Instead of measuring multiple times, the hammer velocity calculating method and program is suggested by this article for general cases and the input parameters will be changed for the other cases. The calculation results are verified by using a high speed camera to measure the hammer velocity.

The first principle calculation was employed to investigate the formation energies and structural, electronic, and magnetic properties of intrinsic and Ni-doped sodium bismuth titanate Bi0.5Na0.5TiO3(BNT). The obtained formation energies indicate that Ni atoms prefer to dope into Bi-sites in the lattice of BNT while the calculated band structure shows that the doping leads to the emergence of new midgap energy states in the bandgaps, reducing the bandgap value of doped materials.
