Summary: Two-dimensional hexagonal boron nitride materials have unique properties for electronics applications, but the current production capacity for BN nanostructures lags behind that for carbon-based nanostructures. In this study, a ReaxFF-based force field was developed to model the gas-phase chemistry for BNNS synthesis. The simulations showed that BN precursors led to the formation of closed BNNSs, while the HBNH precursors formed smaller and lower-quality BNNSs. Additives like H2 had a significant impact on BNNS formation.

Summary: In this study, hexagonal boron nitride (h-BN) was used for the surface modification of titanium (Ti) to achieve high reactivity for hydrogen (H-2) absorption. The Ti modified by h-BN could absorb approximately 3 wt % of H-2 at 40 degrees C within 10 min and the functional surface was maintained even after dehydrogenation at high temperatures.

Summary: In this study, the friction coefficient of water on graphene/h-BN heterostructures was investigated using molecular dynamics simulations. The results showed a non-monotonic but symmetrical variation with relative interlayer angle. The graphene/h-BN heterostructure is a device with different friction coefficients on both sides and can be adjusted by twisting the relative interlayer angle.

Summary: DFT computations were used to investigate the adsorption performance of hydrogen molecules over transition metals embedded graphitic carbon nitride, showing that Os-embedded gCN has superior interaction with H-2 molecules. The maximum storage number of adsorbed H-2 molecules was found to be 6. Adsorption of H-2 molecules converted the semi-conductive behavior of the systems to a conductive state.

Summary: Inspired by lattice-porous graphene and mesoporous MXenes, lattice-penetrated porous titanium nitride, Ti12N8, was proposed and verified using density functional theory calculations. The study investigated the stabilities, mechanical and electronic characteristics of Ti12N8 and found that it exhibited high thermal and kinetic stabilities, reduced stiffness, and increased catalytic adsorption sites. With different terminations and lattice channels, Ti12N8 showed potential for various applications such as photocatalytic water splitting and selective gas adsorption. These excellent characteristics make Ti12N8 a promising material for flexible nanodevices with tunable properties.
