https://www.selleckchem.com/products/brivudine.html Well-controlled band engineering of a blue phosphorus/C2N van der Waals (vdW) heterojunction is investigated by density functional theory (DFT) calculations. The heterojunction has a natural type-II band alignment with a direct band gap value of 1.514 eV, which gives the enormous potential for solar cell applications. When the heterojunction is under solar illumination, the photogenerated electron-hole pairs can separate out on the disparate monolayers effectively. It induces the formation of spatially indirect excitons. Furthermore, it is found that the band gap of this heterojunction exhibits approximately linear variation with respect to the perpendicular external electric field. Very interestingly, a band alignment change from type-II to type-I occurs at an applied electric field of -0.2 V Å-1. This characteristic provides an attractive possibility to obtain novel multifunctional devices.Although zwitterionic hydrogels exhibit excellent hemocompatibility, their extremely low tensile strength is an obstacle for their use in blood-contacting devices. Electrospun fiber scaffold-reinforced zwitterionic hydrogels are a possible solution to overcome the challenges of both mechanical strength and hemocompatibility. In this work, electrospun polyurethane (ePU) fiber scaffold-reinforced sulfobetaine methacrylate (SBMA) hydrogels (SRgels) were prepared. The SRgels exhibited 4.7 ± 0.5 MPa tensile fracture stress, while the interpenetration between the hydrogel and the fiber scaffold remained intact even under 2.8 MPa tensile stress at 3.0 mm mm-1 strain load; this confirms that the SRgels maintain excellent hemocompatibility for both blood cell adhesion and fibrinogen adsorption under physiological dynamic loading and that dynamically structural matching is achieved between the scaffold and the zwitterionic hydrogels. Mechano-induced self-enhancement was also observed after preloading more than 2.0 mm mm-1 tensile strain
