The solvation structure of Zn<sup>2+</sup> is regulated through incorporating acetonitrile (AN) into the electrolyte, elevating nucleation sites and stablizing zinc metal anode, as revealed by complementary theoretical experimental studies.
Metallic Zn is a preferred anode material for rechargeable aqueous batteries towards smart grid and renewable energy storage.

Abstract Advances in deep learning have greatly improved structure prediction of molecules. However, many macroscopic observations that are important for real-world applications not functions a single molecular but rather determined from the equilibrium distribution structures. Conventional methods obtaining these distributions, such as dynamics simulation, computationally expensive and often intractable. Here we introduce framework, called Distributional Graphormer (DiG), an attempt to...
