Abstract: Blueberry anthocyanins have strong antioxidant activity, but their instability and low bioavailability limit their use. Nanoemulsions are new type of food and drug carrier with stable thermodynamic properties. Therefore, anthocyanins will be encapsulated with nanoemulsions to improve their stability and application value. In this study, the best surfactants, oil phases and cosurfactants for the preparation of blueberry anthocyanin nanoemulsions were screened by pseudo-ternary phase diagram method and the solubility of blueberry anthocyanin nanoemulsions were taken into consideration. Deep purplish red, clear and transparent anthocyanin nanoemulsions were prepared by simple and cheap low-energy emulsification method according to the formula. Normal and high temperature test and high speed centrifugal test proved that the blueberry anthocyanin nanoemulsions had good stability. Guinea pig skin irritation test and sensitization test showed that there was no irritation and sensitization to guinea pig hair removal skin. In conclusion, the blueberry anthocyanin nanoemulsions prepared in this study have good stability at room temperature and are safe for guinea pig hair removal skin. It provides a reference for the application of blueberry anthocyanins in skin beauty and transdermal drug delivery.Abstract: Blueberry anthocyanins have strong antioxidant activity, but their instability and low bioavailability limit their use.

Abstract: As the post-Moore era evolves, the introduction of novel two-dimensional materials has boosted the development of spintronics. Recently experimentally synthesized hexagonal boron carbon nitrogen (h-BCN) monolayers exhibit intriguing electronic properties, which have greatly attracted the interest of researchers. In this paper, the electronic structure and electrical transport properties of two-dimensional h-BCN nanosheets and one-dimensional h-BCN nanoribbons are investigated using first-principles-based density-functional theory combined with nonequilibrium Green's function calculations. The 2D h-BCN monolayers not only have the same hexagonal structure as graphene and boron nitride (h-BCN), but also exhibit semiconducting properties from the energy band structure with a band gap value of 1.17 eV. In addition, the bandgap variation of the sawtooth-type (Z-type) h-BCN nanoribbons is correlated with the bandwidth, while that of the armchair-type (A-type) h-BCN nanoribbons is independent of the bandwidth. On this basis, the device model based on Z-type h-BCN nanoribbons is further constructed. The transport properties of the Z-type h-BCN nanoribbon devices with different bandwidths are related to the spin direction, and exhibit perfect negative differential resistance (NDR) effect from the voltammetric characteristic curves. Finally, the internal mechanism of quantum transport is deeply understood by analyzing the local density of states. The results show that the two-dimensional h-BCN nanosheets have direct semiconductor behavior, and the spin-dependent transport properties and NDR effect of the Z-type h-BCN nanodevices are of great significance in the design of multifunctional spin nanodevices.Abstract: As the post-Moore era evolves, the introduction of novel two-dimensional materials has boosted the development of spintronics.
