Group IV Monochalcogenides MX (M=Ge, Sn; X=S, Se) as Chemical Anchors of Polysulfides for Lithium-Sulfur Batteries.
TL;DR: This work reports phosphorene-like MX (M=Ge, Sn; X=S, Se) monolayers as promising anchoring materials to restrain the lithium polysulfides shuttling and shows that excellent surface diffusion of Li and polysolfides endow a fast charge/discharge rate for lithium-sulfur batteries.

Mechanism of p-type-to-n-type conductivity conversion in boron-doped diamond
TL;DR: In this article, the role of two boron-hydrogen complexes in conductivity conversion from p-type to n-type in diamond samples was investigated, and it was shown that the transformation from the BH1 into BH2 and/or BH3 complexes may explain the phenomenon of conversion from P-type-to-n-type conductivity through deuteration.

TL;DR: In this article, a one-step simultaneous photo-deposited method was proposed to precisely locate Pd and PPy nanoparticles on TiO 2, in other words, the places where Pd was deposited are just the active sites that the photoinduced electrons and holes participated in the photocatalytic reaction, which is beneficial for separation of photo-induced carriers.

Intrinsic defect in BiNbO4: A density functional theory study
Abstract: Formation energies, transition energy levels, and electronic properties of various intrinsic defects in BiNbO4 systems are studied based on the first-principles density-functional theory. Our results indicate that the acceptor defects form easier than donor defects under O rich condition, while it is opposite under Bi rich condition. Under O-rich condition, Bi vacancies (Bivac) leading to p-type conductivity are the dominant intrinsic defects, whereas O vacancies (Ovac) inducing moderate n-type conductivity are the dominant intrinsic defects under Bi-rich condition. Among these intrinsic defects, Ovac is a deep donor; to the contrary, Bivac is found to be a shallow acceptor which is benefit to the separation and migration of the photogenerated carriers. Consequently, the BiNbO4 with Bivac under O-rich growth condition should be of better photocatalytic performance.
