Abstract: A modified distiller's, a preparation method thereof, and a use thereof are provided, which relate to the field of composite material preparation. Coupling agents with different reactive groups and hyperbranched resins with different terminal reactive groups are used, and through synergistic effect of the coupling agent and the hyperbranched resin, the surface of distiller's grains powder is regulated. This approach solves problems of poor interfacial compatibility between the distiller's grains powder and the biodegradable resin, as well as agglomeration of the distiller's grains powder due to strong hydrogen bonding. As a result, the compatibility and interfacial bonding strength between the distiller's grains powder and the biodegradable resin are enhanced, leading to the production of a high-performance fully biodegradable green composite material.

Abstract: A vehicle light or components design that recycles waste heat from the light source and has an additional heating element attached to radiator vents that creates and distributes heated air inside the vehicle light. This is an optically neutral and energy-efficient lens heating system that prevents snow buildup on the outside of the light in cold and wet weather, allowing for more efficient and therefore safer lights for vehicles. As each ceramic heating element receives electricity from the vehicle, its surface heats up. Blower fans harvest and blow the waste warm air past the heating elements through the radiator vent. It becomes hot air. A temperature sensor regulates the amount of additional electricity that is sent to each ceramic element. An overheat protection sensor measures the radiator temperature to ensure material thermal safety, and an ambient temperature sensor measures the outside temperature to determine when the system should be activated.

Abstract: A vehicle light has a heating element and a radiator vent that creates and distributes heated air inside the vehicle light. This prevents fog buildup on the inside of the light in cold and wet weather, allowing for more efficient and therefore safer lights for vehicles. A series of ceramic heating elements is arrayed in front of individual spines of a radiator vent. As each ceramic heating element receives electricity from the vehicle, its surface heats up. Air is blown past the heating elements and directed through the radiator vent by two or more blower motors. A temperature sensor regulates the amount of electricity that is sent to each ceramic element.
