Abstract: A device for producing black phosphorus which includes a reactor having one end connected to a feeding pipe and another end connected to a discharge pipe; a propeller blade unit including a rotating shaft mounted between the two ends of the reactor and a blade element mounted on the rotating shaft; a motor connected to the rotating shaft for controlling a rotation speed of the blade element; a heating device enclosing the reactor at an outer side and defines the reactor into a plurality of heating zones; and an inert gas input connected to the discharge pipe. The device is simple and safe in operation, can optimize the production process at low cost, and has high level of automation, thus facilitating a continuous production of black phosphorus under normal pressure.

Abstract: A method of producing black phosphorus which includes the steps of: weighing and mixing reaction raw materials which comprises metallic tin, red phosphorus and monocrystalline iodine, wherein a weight ratio of tin: red phosphorus: iodine is 0.6-3.5: 5-45: 0.1-0.8; feeding the mixture to a high-temperature resistant metal reaction tube; removing air by introducing inert gas and sealing the reaction tube tightly; placing the metal reaction tube inside a muffle furnace for carrying out calcination reaction by first increasing a temperature at a preset rate to a maximum temperature and keeping warm and then decreasing a temperature at a preset rate and keeping warm, then to room temperature so that the black phosphorus is produced. The conversion rate is very high and the quality of the produced product is classified as high quality.

Abstract: Various systems and methods for providing network services are described herein. In one example, a method includes receiving, via a first processor, a network packet from a source device. The method can also include sending, via the first processor, the network packet to a second processor if a service subsystem and a service are responsive. Furthermore, the method can include modifying, via the second processor, the network packet or generating a new packet based on the service. The method can also include receiving, via the first processor, the modified network packet or the new network packet from the second processor. The method can also further include sending, via the first processor, the modified network packet or the new network packet to a destination device.
