Abstract: Systems and methods for an active emissive layer configured for use in an electroluminescent device. The active emissive layer includes a host-guest blend in which the host includes a perovskite (e.g., CsPbBr3, CsPbCl3, and/or CsPbI3) and the guest includes quantum shells (QSs) embedded in the host. The QSs include a quantum-confined, spheroidal shell that is a first semiconductor (e.g., CdSe) sandwiched between a core and an outer layer that are a wider band gap semiconductor (e.g., CdS). The active emissive layer is formed by mixing a perovskite solution with a colloid to generate a blended mixture, where the colloid is the QSs suspended in a same solvent used for the perovskite solution. The perovskite solution is coated on a substrate to form a film that is then annealed, and electrodes are formed to flow a current through the active emissive layer, causing emitted light.

Abstract: The present invention relates to substituted benzophenones of structural Formula I employed as small molecule inhibitor for controlling obesity. The present invention further relates to screening of small molecule inhibitors against p300 which selectively targets histone butyrylation thereby specifically inhibiting adipogenesis further aiding to prevention of weight gain. The present invention reveals that histone butyrylation increases during adipogenesis. Hence, inhibition of histone butyrylation by a small molecule inhibitor would be a promising therapeutic strategy to control obesity. Significantly, besides inhibiting adipogenesis in cellular model, it also prevents weight gain in high fat diet based mouse model system, indicating the possible use of the scaffold for obesity control.

Abstract: Active emissive layers (e.g., of a light-emitting electrochemical cell (LEC)) are provided and can comprise zero-dimensional (0D) perovskite material in combination with a three-dimensional (3D) perovskite material, as well as electroluminescent devices (e.g., LECs) utilizing such active emissive layers and methods of fabricating and using such active emissive layers and electroluminescent devices. The 0D perovskite material can be incorporated into a matrix film of the 3D perovskite material. The 0D perovskite material can be, for example, perovskite nanocrystals (PNCs). The 0D perovskite material can be, for example, Cs4PbBr6, and the 3D perovskite material can be, for example, CsPbBr3.
