Abstract: The invention relates to ruxolitinib crystal and a pharmaceutical composition thereof. In particular, the invention provides ruxolitinib dihydrate crystal and a preparation method thereof, and ruxolitinib free base in amorphous form and a preparation method thereof, and a pharmaceutical composition comprising ruxolitinib dihydrate crystal or ruxolitinib free base in amorphous form. The crystal, amorphous form and pharmaceutical composition of the invention have simple preparation method, high product yield, and excellent crystal stability, hygroscopicity and processability, and thus are suitable for industrial production.

Abstract: An embodiment of this application discloses a device management method. A first network management device may obtain subscription parameter information, where the subscription parameter information is used to indicate a subscription parameter used during a process of establishing a first subscription session, and the first subscription session is used to indicate a first network device to send subscription data to a network management device managing the first network device. After the first network management device determines that the first subscription session is interrupted, the first network management device may generate a request message based on the subscription parameter information, and send the request message to a network device managed by the first network management device.

Abstract: A photoresist bottle capable of improving poor coating coverage is disclosed, which comprising: a sealed photoresist bottle body having a connector, a hard groove-shaped projection fixed on the bottom of the bottle body, an inner liner having an opening at the bottom, which is hermetically connected to the groove sidewall of the projection and is used to fill with the photoresist, a nitrogen gas tube inserting into the interspace between the bottle body and the soft liner through the connector, and a photoresist conduit inserting into the soft liner through the connector. Wherein, the top of the inner liner is hermetically connected to the upper lateral wall of the photoresist conduit, the lower end of the photoresist conduit reaches within the groove of the projection. When the soft liner is pressured, since unable to touch the photoresist outlets at the lower end of the photoresist conduit, a blocking can be avoided. Thereby, air bubbles and coating problems are prevented.

Abstract: A method of extracting germanium from a germanium deposit using a thermal reduction process is disclosed. The method includes: adding sodium monophosphate to a germanium deposit to obtain a mixed germanium deposit; isolating the mixed germanium deposit from air; increasing the temperature and then baking the mixed germanium deposit; and obtaining a germanium concentrate after volatilization of the mixed germanium deposit.

Abstract: Provided is a method and apparatus for secondary enrichment of germanium from low-grade lignite germanium concentrates in vacuum, and particularly a method and apparatus for secondary enrichment and recovery of germanium from low-grade lignite germanium concentrates with microwave heating in vacuum, which belongs to a germanium extraction method and apparatus in the field of metallurgy.

Abstract: A method of extracting germanium from a germanium deposit using a thermal reduction process is disclosed. The present disclosure relates to a method of extracting germanium, which belongs to the field of metallurgy technologies of nonferrous metal, and particularly relates to a method of extracting germanium from a germanium deposit through thermal reduction, volatilization and concentration using sodium monophosphate as a reducing agent. The method of the present disclosure includes: adding sodium monophosphate to a germanium deposit; isolating from air; increasing the temperature and baking the germanium deposit; and obtaining a germanium concentrate after volatilization and concentration of the germanium deposit. Through baking the germanium deposit at 1,000° C., volatilization and concentration of the germanium deposit, the germanium recycling rate exceeds 96% when sodium monophosphate weighing 2.5% of the germanium depositis added.
