Summary: The stability enhancement mechanism of honeycomb borophene on Ti2C substrate was systematically investigated, and the epitaxial growth model was proposed based on comparative total energy calculations. The results showed that planar honeycomb borophene layer is energetically favorable on Ti2C substrate with strong substrate-induced interactions. Boron adatoms easily migrate and form clusters along hollow sites on the surface, leading to the formation of six-membered boron islands.

Summary: Metal boride nanostructures have great potential for hydrogen storage applications. However, their synthesis is challenging due to high surface energy, strong bonding, and difficult surface termination. Mechanochemical exfoliation of magnesium diboride in zirconia produces ultrathin MgB2 nanosheets with high yield. High-pressure hydrogenation and dehydrogenation of these nanosheets reveal a hydrogen capacity 50 times larger than bulk MgB2. The enhancement is attributed to defective sites created by ball-milling and incomplete Mg surface coverage. The exfoliation and creation of ultrathin layers offer a promising direction for high-capacity hydrogen storage.

Summary: In this study, a new class of piezoresistive nanocomposites was developed by mixing different types of 2D nanosheets. It was found that the conductivity of each nanocomposite type exhibited a different dependence on filler volume fraction, and they also showed different piezoresistive properties. This research expands the understanding of piezoresistive nanocomposites and provides a platform for the engineering of high-performance strain sensors.

Summary: This work demonstrates that graphene nanoplatelets (GNPs) and other two-dimensional materials (2DMs) can act as protective barriers against the fading of architectural paints and inks used in art. These materials provide a new approach for improving the lightfastness of colors, showing superior resistance to fading under UV radiation or visible light exposure. The mechanisms of protection differ for GNPs and other 2DMs, with GNPs scavenging free radicals and absorbing UV light, while other 2DMs trap reactive oxygen species and corrosive gases. Colorimetric measurements show an extended lifetime of the 2DM-doped inks and paints by up to approximately 40%.

Summary: Localized electrical breakdown measurements were performed on 2D muscovite mica flakes using Conduction Atomic Force Microscopy. The results showed that muscovite mica has high electrical breakdown strength and low leakage current, comparable to hexagonal boron nitride. However, a significant difference is that muscovite mica requires very low current to avoid catastrophic damage, even for very thin flakes.

Summary: In this study, TiB2 nanosheets were exfoliated and added to CaO material, and it was found that adding just 1% of nanosheets can enhance the capturing capacity of CaO up to 25% and reduce the sintering of CaO. Minimally functionalized nanosheets derived from TiB2 were used to investigate the effect of the density of functional groups on the CO2 capturing ability of CaO, and preliminary insights on the reaction mechanism and rate parameters of CO2 adsorption on CaO were obtained.

Summary: Titanium diboride (TiB2) is a layered ceramic material with a promising structure for utilizing the rich chemistry of titanium and boron. Recent efforts have focused on exfoliating TiB2 into ultrathin nanosheets, which exhibit crystalline nature and vacancies that facilitate chemisorption. Density Functional Theory (DFT) studies show that nanosheets with more vacancies have higher adsorption capacity for N-2 compared to nanosheets with fewer vacancies and bulk TiB2.

Summary: This study serendipitously discovered a fluorescent dispersion of CQDs formed through a simple contact between a common polymeric material and an organic solvent. The CQDs display blue fluorescence, have a size range of 2-5 nm, are nitrogen functionalized, and exhibit a good degree of crystallinity. This counterintuitive insight provides important guidance for experimental design.
