Abstract: A developing cartridge includes a housing for accommodating a toner, a developing roller rotatably mounted in the housing, a doctor blade in contact with the developing roller, and a driving device located at a longitudinal end of the housing. The driving device includes a driving force receiving part for receiving a driving force from the outside of the developing cartridge, and is configured to drive the developing roller to rotate. The doctor blade is in contact with a surface of the developing roller to adjust a thickness of a toner layer on the surface of the developing roller. When viewed along a longitudinal direction of the developing cartridge, at least the driving force receiving part does not overlap with the doctor blade. At a moment when the driving force is received by the driving force receiving part, a vibration transmitted to the doctor blade and the developing roller is reduced.

Abstract: Provided herein are methods for identifying and isolating polynucleotides coding for polypeptides having D-allulose 3-epimerase activity from a wide variety of microorganisms. Also provided are nucleic acid constructs, vectors and recombinant host cells comprising the polynucleotides coding for D-allulose 3-epimerase activity as well as methods for producing allulose from fructose using said recombinant host cells having D-allulose 3-epimerase activity or the D-allulose 3-epimerase enzyme of said recombinant host cells having D-allulose 3-epimerase activity.

Abstract: A method for preparing a material composition comprising a hollow transition metal oxide nanoparticle supported upon a carbon material support includes a solution impregnation process step, followed by a thermal reduction process step and finally a thermal oxidation process step. The material composition, an electrode and an electrical component such as but not limited to a battery are all predicated at least in-part upon the material composition prepared in accord with the foregoing method. The foregoing material composition, electrode, battery and method may ultimately provide a LIB with enhanced performance.

Abstract: Disclosed is a steel wire rope for conveyor belts. The steel wire rope includes a central steel wire, a steel wire layer externally wound on the central steel wire, and a plurality of external steel wire strands. Each external steel wire strand includes a core steel wire and N external steel wires. The central steel wire, the steel wire layer externally wound on the central steel wire, and the plurality of external steel wire strands are wound into a steel wire rope for conveyor belts in one step. The steel wire layer is externally wound on the outer side of the central steel wire, the external steel wire strands are wound to wrap the outer side of the steel wire layer, and the external steel wire strands are in line contact with the steel wire layer.
