Abstract: A device management method includes a first network device sending a first remote procedure call (RPC) request message to a second network device, where the first RPC request message includes information about a third yet another next generation (YANG) module that is identifiable to the first network device. After the second network device switches to the third YANG module, the first network device establishes a control session between the first network device and the second network device based on the third YANG module. When the network device supports switching between YANG modules of different standards, the second network device is notified, by using an RPC, to switch to a YANG module supported by the first network device.

Abstract: A processing cartridge can be detachably installed in an electronic image forming device, where a protrusion capable of extending and retracting along a vertical direction is disposed inside the electronic image forming device. The processing cartridge includes a toner container and a waste toner container; and a movable element disposed at the lower side of the processing cartridge. The processing cartridge further includes a detachment preventing portion; the movable element is disposed with an abutting portion; and the abutting portion is capable of being abutted against the detachment preventing portion to prevent the movable element being disengaged. The processing cartridge further includes an elastic element; and the elastic element is configured to move the movable element toward the lower side of the processing cartridge.

Abstract: The present disclosure provides a fluorescent nanomaterial and a preparation method and applications thereof, and the preparation method comprises: subjecting amphiphilic molecules in a solvent system to an illumination treatment and/or a heat treatment to obtain fluorescent nanomaterials. The preparation of fluorescent nanomaterials provided by the present disclosure is simple in process, simple and easily available in raw materials and requires neither additional addition of a strong acid, a strong alkali, a passivating agent and the like, nor high temperature and high pressure in the preparation process. The whole process is environmentally friendly and pollution-free and the products can be used in various fields.

Abstract: The present disclosure provides a recycling method of amphiphilic surface-active pollutants in water, comprising: performing a polymerization reaction by illumination treatment on the amphiphilic surface-active pollutants in water to form a polymerization product; performing self-assembly on the polymerization product for aggregation to form a fluorescent material, and performing separation to obtain a recycled product. Through treatment of the amphiphilic surface-active pollutants by illumination, the present disclosure can realize the recycled utilization of the amphiphilic pollutants in the wastewater by one step of reaction, so that the amphiphilic surface-active pollutants can be converted into usable fluorescent materials, and the biological toxicity is greatly reduced.
