Material transport device with shut-off valves. The present invention relates to a system and method for transporting particulate material. A plurality of injector assemblies are positioned along the transport pipeline to inject a continuous flow of transport gas into the pipeline. The continuous flow of transport gas injected by each of the injector assemblies prevents particulate material from entering any part of the injector assemblies, thereby reducing the risk of blockage of nozzles, injection path selection valves, and so on. The continuous injection of transport gas along the pipeline also maintains a degree of permeability of the particulate material in the pipeline and promotes stable transport.The pilot-operated shut-off valve of each injector assembly is operable to independently detect a large pressure drop in the pipeline, and to close in order to store pressurized carrier gas in the injector assembly and feed it.

The present invention relates to a device for applying decorative particulate material such as glitter to an object.

By using the device in this manner, users can decorate objects of interest such as one or more of their fingernails.

This invention relates to the preparation technology of two-dimensional material composites, specifically a method for coating two-dimensional materials onto the surface of non-metallic particles based on a high-temperature growth process. This method is suitable for the large-scale preparation of continuously coated non-metallic particulate materials. The invention employs a three-step method to form continuously coated two-dimensional materials on the surface of non-metallic particles: First, a continuous metal catalyst coating layer with a nanometer-thickness is formed on the surface of the non-metallic particles; then, the coated non-metallic particles are mixed with micron-sized powder of the same metal catalyst composition; next, a continuously coated two-dimensional material film is grown on the surface of the non-metallic particles using a high-temperature catalytic reaction; finally, the metal catalyst is removed, yielding the two-dimensional coated non-metallic particulate material. This invention can achieve the formation of two-dimensional material coating layers on the surface of a large number of non-metallic particles. The two-dimensional materials exhibit continuous, non-overlapping microstructures, high coating rates, and high crystallinity. Furthermore, this method is easily scalable.
