Abstract: The present invention belongs to the technical field of biomass carbon materials, and relates to a lignin porous carbon nanosheet, a preparation method therefor, and an application thereof in supercapacitor electrode materials. The method of the present invention performs layer-by-layer self-assembly of sulfonated lignin and oxalate in a selective solvent to prepare a layer-by-layer self-assembled lignin/oxalate composite, which is then carbonized and pickled to obtain the lignin porous carbon nanosheets. The lignin porous carbon nanosheets prepared by the above method of the present invention have a specific surface area of 200-1500 m2/g, a micropore specific surface area of 100-500 m2/g, a mesoporous specific surface area of 100-1000 m2/g, a pore diameter of 0.5-30 nm, and a pore volume of 0.5-1.5 cm3/g; they can be applied to supercapacitor electrode materials, showing higher specific capacitance and excellent rate performance (with a specific capacitance retention rate of 76.

Abstract: Disclosed are a full-automatic storage shelf assembly production line and an operation method thereof. The production line includes a logistics channel, a stand column-based feeding area, a supporting beam-based feeding area, an in-line logistics system, a shelf assembly area, a finished product area, and a control system. The stand column-based feeding area, the supporting beam-based feeding area, the shelf assembly area, and the finished product area are connected in series by means of the in-line logistics system to form an integrated production line.

Abstract: Provided is a cocktail of factors for converting/reprogramming non-naïve pluripotent stem cells into TGF? signaling-independent (TSI) naïve induced pluripotent stem cells (iPSCs). Also provided are methods for reprograming a non-naïve PSC into a TSI naïve iPSC by contacting the cell to be reprogrammed with effective amounts of compounds for a sufficient period of time to reprogram the cell into a TSI naïve iPSC.

Abstract: A core-shell nanoparticle is provided. The core-shell nanoparticle has a core comprising a metal fluoride doped with a first sensitizer and a shell surrounding the core, wherein the shell comprises a first layer comprising the metal fluoride doped with a second sensitizer and a first activator, and a second layer comprising the metal fluoride doped with a third sensitizer and a second activator, wherein the first activator and the second activator are different, and each is independently selected from the group consisting of Tm3+, Ho3+, and combinations thereof. A method of generating an optical signal using the core-shell nanoparticle and a method of preparing the core-shell nanoparticle is also provided.
