Summary: Adhesion property and bonding characteristic between ceramic TiN and two-dimensional MoS2 (2D-MoS2) were investigated by first-principles simulation. Results show that 2D-MoS2 can adhere to TiN, with the Ti/S interface having a larger bonding strength than the N/S interface. Analysis of charge density at the Ti/S interface indicates the formation of chemical bonds between interfacial atoms, mainly contributed by hybridization of Ti-3d and S-2p orbitals.

Summary: In this study, a new methodology for selective and sensitive pathogen detection is proposed using a 2D layered heterostructured biosensing platform. The platform is based on the immobilization of functionalized molybdenum disulphide onto graphene screen-printed electrodes. Electrochemical impedance spectroscopy is used to detect and quantify SARS-CoV-2 spike RBD recombinant protein with a low detection limit. The biosensor shows selectivity even in the presence of interfering proteins and can detect SARS-CoV-2 S1 protein in nasopharyngeal swab samples.

Summary: This paper presents a method for the direct laser synthesis of periodically nanostructured 2D transition metal dichalcogenide (2D-TMD) films from single source precursors. Laser synthesis of MoS2 and WS2 tracks is achieved by localized thermal dissociation of Mo and W thiosalts, caused by the strong absorption of continuous wave (c.w.) visible laser radiation by the precursor film. Moreover, the formation of isolated nanoribbons with extreme periodic modulation in the thickness of the laser-synthesized TMD films is observed, which is attributed to the effect known as laser-induced periodic surface structures (LIPSS).

Summary: In this study, a porous Cu mesh was utilized as a current collector to investigate its morphological effect on supercapacitor performance. The porous surface was achieved through thermal annealing with ammonia gas. Hierarchically porous activated graphene (AG) was deposited on the P-Cu mesh, resulting in high specific capacitance and energy density due to efficient electric double-layer formation and charge transport. This work presents an alternative approach to enhance supercapacitors by combining a porous metallic current collector with porous AG.
