摘要： The disclosure discloses a perovskite film layer, a device and a preparation method for effectively improving the efficiency of perovskite optoelectronics. The perovskite film layer consists of a layer with discontinuous, irregularly distributed perovskite crystal grains and an organic insulating layer with a low refractive index embedded between the perovskite crystal grains. The perovskite crystal grains form a plurality of convex portions, and the organic insulating layer forms a plurality of concave portions between the convex portions. By adding an excess of an alkylammonium salt and/or an organic molecule with a specific functional group to perovskite precursor solution, a concave-convex film layer structure is spontaneously formed, and an upper charge transport layer and an electrode form pleated concave-convex structures. Such a special perovskite thin film structure formed by a simple solution method can effectively improve the light-outcoupling efficiency and enhance the performance of the perovskite light-emitting device.

摘要： The invention relates to a method for preparing a composite metal oxide hollow fibre. A certain stoichiometry of composite metal oxide raw material and a polymer binding agent are added to an organic solvent, and mixed mechanically to obtain an evenly dispersed spinning solution having a suitable viscosity. After defoaming treatment, the spinning solution is extruded through a spinneret and, after undergoing a certain dry spinning process, enters an external coagulation bath; during this period, a phase inversion process occurs and composite metal oxide hollow fibre blanks are formed. The blanks are immersed in the external coagulation bath and the organic solvent is displaced; after natural drying, the blanks undergo a heat treatment process; during this period, polymer burn off, in situ reaction, and in situ sintering processes occur to obtain the composite metal oxide hollow fibre.

摘要： Provided is a cleaning process of producing lactic acid. Firstly saccharification liquid is prepared through saccharated materials, then fermented with nutritive materials and lactic acid bacteria, and liquid alkali is used to adjust the pH. The fermentation broth is filtrated with porous membrane, and the lactic acid bacteria in the interception liquid are then reintroduced into the porous membrane for recycling. The permeate from porous membrane is subjected to nanofiltration to be decolored and purified. The concentrated solution from nanofiltration and the cleaning liquid from fermentation tank and its affiliated equipment are filtrated and sterilized by using ceramic membrane, and then are reintroduced into the fermentation unit for recycling. The permeate from nanofiltration is then subjected to bipolar electrodialysis system to prepare lactic acid, and the liquid alkali produced at the same time is reintroduced into the fermentation tank for recycling. The lactic acid is finally concentrated by using vacuum distillation. The process recycles the bacteria in the liquid alkali and matured fermentation broth, and is characterized by low material consumption and emission, low pollution, reduced cost and cleanness and environmentally protection of the whole production process.
