Abstract: A non-metal catalyst for synthesizing polycarbonate by CO2 and a preparation method therefor are provided. The preparation method of the non-metal catalyst includes the following steps: dissolving a hydroxyl functionalized organic ammonium halide monomer, a quaternary phosphonium salt monomer, and a hydroxyl functionalized imidazole salt monomer in a solvent, and polymerizing the mixture under the action of an initiator to obtain the non-metal catalyst for synthesizing the polycarbonate by using CO2. The non-metal catalyst prepared by the present invention is used as a heterogeneous catalytic material, is applied to a system for preparing polycarbonate by a one-step copolymerization reaction of CO2 and an epoxy compound, has high catalytic activity, does not need an additional cocatalyst or a solvent, efficiently converts CO2 into the polycarbonate, has no impurities such as metal in the product, and has the advantages of easy separation, recycling, and the like.

Abstract: A violet blue gradient color, blue light resistant and full-screen tempered privacy screen protector, comprising an electroplated oleophobic layer, a diamond explosion-proof layer, a tempered coating, a flexible explosion-proof layer, a silk screen reinforcing layer, a composite violet blue gradient and blue light resistant layer and a privacy protection layer, wherein the composite violet blue gradient and blue light resistant layer comprises a violet blue gradient film and a blue light resistant film. By the nanotechnology used in the present invention, existing spy-proof layers can be coated to be violet blue gradient and blue light resistant layers, and compared with the prior art, the blue light resistant layers can be coated more efficiently and rapidly, so that a plurality of layers are integrated with high efficiencies and yield. The composite violet blue gradient and blue light resistant privacy layer has integrated refraction effects on the basis of existing louver technologies.

Abstract: Described is a novel process for disaggregating biomass pyrolysis oil quantitatively into energy dense hydrophobic aromatic fraction (HAF), fermentable pyrolytic sugars and phenolics based products in a highly economical and energy efficient manner. Phase separation of the esterified pyrolysis oil after an oxidative pre-treatment and the quantitative recovery of the separate fractions is described. Phase separation uses batch as well as continuous reactor systems. The resulting HAF is an energy dense, thermally stable, water free, non-corrosive to carbon steel, and is a free flowing liquid suitable for combustion and for upgrading to transportation fuels. Pyrolytic sugars which are mainly anhydrosugars can be further converted by fermentation to ethanol or other products. Monomeric phenols are useful industrial intermediates and the organic acids in the original pyrolysis oil are mainly recovered as esters of the separation solvents.

Abstract: The present invention relates to generation of an exercise plan. In an embodiment of the present invention, a method for generating an exercise plan from a plurality of exercises for a user is proposed. Each exercise of the plurality of exercises is associated with a parameter for indicating the status of said each exercise of the plurality of exercises. The parameter may be set to different values. For example, the parameter may be set to a first value indicates that the associated exercise has not been selected to be part of the exercise plan; similarly, a second value indicates that the associated exercise has been selected to be part of the exercise plan; and a third value indicates that the associated exercise has been performed by the user.
