WebJan 13, 2024 · Abstract Solvation plays a pivotal role in chemistry and biology. A solid-state analogy of solvation is polaron formation, but the magnitude of Coulomb screening is typically an order of magnitude weaker than that of solvation in aqueous solutions. WebIn addition, we exploited the formation of magnetic polaron states in Asp-CDs for H 2 O 2 photoproduction via WOR. Sole Asp-CDs were able to produce H 2 O 2 in pure water even without the presence of oxygen, and a further enhancement in H 2 O 2 reaction yield was achieved when 2-propanol was introduced into the reaction mixture, confirming its ...

WebDec 26, 2024 · The formation of polarons is a pervasive phenomenon in transition metal oxide compounds, with a strong impact on the physical properties and functionalities of the hosting materials. In its original formulation, the polaron problem considers a single charge carrier in a polar crystal interacting with its surrounding lattice. WebDisorder fosters small-polaron formation. Unusual transport and optical properties of large and small polarons distinguish them from each other and from conventional electronic carriers. Polarons tend to form in unusually complex materials.
