AI Article Synopsis

  • Density functional theory (DFT) was applied to investigate how well a h-BN monolayer can absorb four flavonoids (apigenin, kaempferol, myricetin, and quercetin) compared to glucose.
  • Results indicate that the flavonoids have a stronger interaction with the h-BN monolayer than glucose, suggesting that the h-BN monolayer selectively adsorbs flavonoids over glucose.
  • Additionally, the study confirms that ethanol can effectively elute the absorbed flavonoids from the h-BN monolayer, enhancing the potential for extraction from bee honey.

Article Abstract

Density functional theory (DFT) was used to explore the possibility of h-BN monolayer acting as an adsorbent for the flavonoids. Four flavonoids named apigenin, kaempferol, myricetin, and quercetin as well as glucose (Glu) were selected as representatives of honey. DFT and ab initio molecular dynamics simulation results show that the four flavonoids interact with the h-BN monolayer much stronger than the Glu does in both vacuum and solutions, indicating a good adsorptive selectivity of the flavonoids over Glu. The interaction of the flavonoids and the Glu with water as well as the solvation energy of the flavonoids in water, methanol and ethanol was obtained using both the PBE-D and B3LYP-D functionals. It is shown that the h-BN monolayer can provide high selective adsorption of the flavonoids from bee honey and ethanol can be used as an elution solvent to recover the adsorbed flavonoids.

ZnSb is widely recognized as a promising thermoelectric material in its bulk form, and a ZnSb bilayer was recently synthesized from the bulk. In this study, we designed a vertical van der Waals heterostructure consisting of a ZnSb bilayer and an h-BN monolayer to investigate its electronic, elastic, transport, and thermoelectric properties. Based on density functional theory, the results show that the formation of this heterostructure significantly enhances electron mobility and reduces the bandgap compared to the ZnSb bilayer, thereby increasing its power factor.

Two-dimensional (2D) materials with spontaneous polarization can exhibit large second-order nonlinear optical (NLO) effects. Here, we present a series of stable distorted monolayers by using first-principles calculations and lattice vibration analysis. The structural distortion leads to a lower polar symmetry, giving rise to intrinsic ferroelectricity with a Curie point up to room temperature.

Creating sustainable and stable semiconductors for energy conversion via catalysis, such as water splitting and carbon dioxide reduction, is a major challenge in modern materials chemistry, propelled by the limited and dwindling reserves of platinum group metals. Two-dimensional hexagonal borocarbonitride (h-BCN) is a metal-free alternative and ternary semiconductor, possessing tunable electronic properties between that of hexagonal boron nitride (h-BN) and graphene, and has attracted significant attention as a nonmetallic catalyst for a host of technologically relevant chemical reactions. Herein, we use density functional theory to investigate the stability and optoelectronic properties of phase-separated monolayer h-BCN structures, varying carbon concentration and domain size.

Interlayer excitons (IXs) in the heterostructure of monolayer transition metal dichalcogenides (TMDs) are considered as a promising platform to study fundamental exciton physics and for potential applications of next generation optoelectronic devices. The IXs trapped in the moiré potential in a twisted monolayer TMD heterostructure such as MoSe/WSe form zero-dimensional (0D) moiré excitons. Introducing an atomically thin insulating layer between TMD monolayers in a twisted heterostructure would modulate the moiré potential landscape, thereby tuning 0D IXs into 2D IXs.
