Summary: A series of mono- and bis-terpyridine complexes of nickel (II) based on a specific ligand have been synthesized and characterized. Different reaction conditions resulted in the formation of new complexes with distinct coordination geometries, as revealed by X-ray crystallography. This study also demonstrates the thermal and luminescent properties of the complexes and the formation of Ni, NiO, and Ni2P2O7 nanoparticles through thermal decomposition.

Summary: This study proposes and investigates the precise cutting of 2D materials, such as graphene, using a combination of a catalyst and an electron beam. Atomistic simulations show that the presence of a nickel catalyst and electron irradiation is crucial for graphene cutting, resulting in cuts with straight edges of about 1-1.5 nm wide. The atomistic mechanism of graphene cutting involves the ejection of two-coordinated atoms at the cut edges bonded to the nickel tip and three-coordinated atoms from the defective graphene structure near the tip.

Summary: In this paper, Ni nanoparticles embedded N-doped carbon nanotubes (CNTs) were decorated on superior thin g-C3N4 nanosheets as a co-catalyst for enhanced photocatalytic performance. The Ni-decorated CNTs (NiCNTs) demonstrated admirable conductivity and unique one-dimensional structure, generating more active sites and efficient charge transfer. The N-doped CNTs promoted charge separation, while Ni nanoparticles trapped photogenerated electrons for photoreduction reaction. The g-C3N4/NiCNTs composites showed excellent hydrogen generation rate and pollutant removal efficiency.

Summary: This study presents a bio-inspired, environmentally friendly technique for metallization of single-walled carbon nanotubes (SWCNTs) using polydopamine (PDA) as an adhesion promoter and electroless plating with nickel. The results showed that prior oxidation of SWCNTs significantly improved the distribution of PDA and nickel. The PDA layer acted as a p-dopant, increasing the Seebeck coefficient of SWCNTs. However, the subsequent metallization decreased the Seebeck coefficient, indicating a need for further optimization.

Summary: The confinement effect induced conformational evolution of one-dimensional (1D) phosphorus atomic chains encapsulated inside carbon nanotubes (CNTs) has been studied. The study shows that as the inner diameter of CNTs increases, the phosphorus chains change from monoatomic linear chain to (P8P2)n chains. These encapsulated (P8P2)n chains exhibit excellent structural stability and can serve as potential building blocks for nano-electronic and molecular electronic devices.

Summary: An in situ method is developed to synthesize Ni3S2 nanowires filled CNTs (Ni3S2@CNTs) and their fundamental properties are investigated. The results show that Ni3S2@CNTs have a core-shell structure with high graphitization degree and excellent resistivity. In addition, a diameter selective electrical breakdown or emptying of the filled nanotube channel is observed when high currents pass through Ni3S2@CNTs.
