Exploring the Properties of an sp-Hybridized All-Carbonatomic Ring, Odd-Number Cyclo[13]Carbon.

The recent breakthrough in synthesizing cyclo[13]carbon (C), an odd-membered all-carbon ring system, represents a significant advancement in developing nontraditional carbon allotropes with reduced structural symmetry. In this study, we systematically investigated the thermal stability, geometric structure, and electronic properties of C using first-principles calculations. Our results show that the C exhibits lower thermal stability due to its low symmetry.

Stable structure and fast ion diffusion: N-doped VO 3D porous nanoflowers for applications in ultrafast rechargeable aqueous zinc-ion batteries.

Aqueous rechargeable zinc-ion batteries (ARZIBs) are promising candidates for fast-charging energy-storage systems. The issues of stronger interactions between Zn and the cathode for ultrafast ARZIBs can be partially addressed by enhancing mass transfer and ion diffusion of the cathode. Herein, via thermal oxidation for the first time, N-doped VO porous nanoflowers with short ion diffusion paths and improved electrical conductivity were synthesized as ARZIBs cathode materials.

Nitrogen-Doped Metallic MoS Derived from a Metal-Organic Framework for Aqueous Rechargeable Zinc-Ion Batteries.

Molybdenum disulfide (MoS) has been extensively studied as a potential storage material for batteries. However, the electrochemical performance of MoS is far from ideal, and it exhibits severe activity fading resulting from its low electronic conductivity. The present work synthesizes nitrogen (N)-doped 1T MoS nanoflowers made of ultrathin nanosheets via the one-step hydrothermal sulfurization of a molybdenum-based metal-organic framework precursor.

Study on the Property of Electron-Transport Layer in the Doped Formamidinium Lead Iodide Perovskite Based on DFT.

The electron-transport layer in planar perovskite solar cells plays an important role in improving photoelectric conversion efficiency. At present, the main electronic transmission materials in perovskite solar cells include TiO, ZnO, WO, ZrO, SnO, ZnO, etc. This work mainly studies the electron-transport characteristics of six different electron-transport layers in perovskite solar cells.
