Abstract: A preparation method of flexible transparent radiation shielding film based on bismuth compounds and its application are provided, in which bismuth compound nanoparticles, polyvinyl alcohol and trace glycerol are mixed to produce a flexible transparent radiation shielding film. The invention disperses the nanoparticles in water to form a stable dispersion, which ensures the homogeneity of the sol obtained by mixing the nanoparticles with polyvinyl alcohol. This invention avoids the decrease in transparency of the composite film as induced by agglomeration of the nanoparticles, achieving a light transmission of over 70% in the visible wavelength band (400-800 nm). With the aid of trace-mount glycerol, the film features long-term stability and flexibility. Importantly, the lead-free film shows a high shielding ability from the medical X-ray band (10-100 keV), which is comparable to Cu foil of identical thickness.

Abstract: The present disclosure provides example methods and apparatuses for handling an exception of an in-vehicle system. One example method includes obtaining a program identifier of a first program, where the first program is a program that runs abnormally. A handling request is sent to a server, where the handling request indicates the server to determine, based on a first mapping relationship, a first handling result corresponding to first exception identification information. The handling request carries the first exception identification information, and the first exception identification information includes the program identifier of the first program. The first mapping relationship records a correspondence between a plurality of pieces of exception identification information and a plurality of handling results, and each piece of exception identification information includes one program identifier.

Abstract: Described herein are compositions and methods relating to light converting luminescent Zero-D perovskite composite materials.

Abstract: A method for forming CsPbBr3 perovskite nanocrystals into a two-dimensional (2D) nanosheet includes providing CsPbBr3 perovskite nanocrystals; mixing the CsPbBr3 perovskite nanocrystals into a mixture of a first solvent and a second solvent, to form a solution of the CsPbBr3 perovskite nanocrystals, the first solvent, and the second solvent; and forming an optoelectronic device by patterning the CsPbBr3 perovskite nanocrystals into a nanosheet, between first and second electrodes. The first solvent is selected to evaporate before the second solvent.
