Summary: We report the successful growth of an optical quality K0.4Rb0.6Pb2Cl5 crystal by the Bridgman method and determine its crystal structure, electronic, and optical properties. The crystal crystallizes in the monoclinic space group P2(1)/c with specific unit-cell parameters. X-ray photoelectron spectroscopy (XPS) measurements reveal low hygroscopicity and partial alteration of the crystal surface. Different exchange-correlation potential approaches are used to study the filling of the valence and conduction bands, with the TB-mBJ + U + SOC approach showing the best agreement with experimental and theoretical data. The optical properties of K0.4Rb0.6Pb2Cl5 are elucidated based on first-principles calculations within the TB-mBJ + U + SOC model.

Summary: This work presents a new mechanism for synthesizing boron carbon nitride (BCN) nanosheets with varying carbon concentration controlled by temperature. The BCN nanosheets were characterized for morphology, layer numbers, crystallinity, chemical composition, and bonding using multiple techniques. The nanosheets' molecular configuration, bonding vibration, and optical properties were analyzed, and the bandgap was determined using theoretical calculations. The thermal treatment of hBN in a graphitic environment demonstrated the control of the morphological, structural, linear, and nonlinear optical characteristics of the synthesized BCN nanosheets, opening up new opportunities for tunable bandgap-based electronics and photonic devices.

Summary: On-surface chemistry allows for the miniaturization of functional devices, with porphyrins being promising building blocks for exploring advanced nanoarchitecture. Covalently connecting molecular units can result in more stable molecular materials with improved charge transfer properties. The synthesis and properties of a covalent molecular network composed of interconnected constituents derived from halogenated nickel tetraphenylporphyrin on Au(111) are addressed in this study. The pi-extended two-dimensional material exhibits dispersive electronic features, while the functional Ni cores retain their single-active site character. The high robustness of transition metal cores provided by bottom-up constructed covalent nanomeshes opens up new possibilities.

Summary: This study reports a novel method for fabricating low valence copper (LVC) material through the spontaneous reaction of red phosphorus (P) and Cu2+. LVC, maintained in an electron-rich state through Cu-P bond, can efficiently activate O-2 to produce reactive oxygen species. The yield of reactive oxygen species reaches a high value of 423 mu mol g(-1) h(-1) using air, surpassing traditional photocatalytic and Fenton-like systems. This work introduces the concept of spontaneous formation of LVC and provides a new avenue for efficient O-2 activation under ambient conditions.

Summary: This study investigated the structures of two Se chains confined inside single-walled carbon nanotubes (SWCNTs), revealing that the chains were linear and parallel. The covalent bond between Se and SWCNT was found to be stronger than that between Se and trigonal Se (t-Se). The interaction between chains was attributed to the overlap of electronic orbitals, and the disappearance of this overlap in the encapsulated Se chains enhanced the covalent bonds.

Summary: In this study, we elucidate the hopping mechanism of hydrogen at intermediate temperature using a combination of experimental data and theoretical calculations. We find that the transition from thermal hopping to quantum tunneling is attributed to resonant tunneling, which is achieved through the resonant tunneling of discrete vibrational states between the edge octahedral site and the tetrahedral site. We also demonstrate that the tunneling rate can be tuned by energy level matching.
