Abstract: The disclosure provides a cell culturing article. The cell culturing article includes a substrate having a surface, a hydrophilic copolymer layer positioned on the surface of the substrate, and a plurality of peptide chains individually conjugated to a surface of the hydrophilic copolymer layer. The hydrophilic copolymer layer is copolymerized by a plurality of polyvinyl alcohol units, a plurality of polyvinyl alcohol derivative units, and a plurality of units containing at least one carboxyl group. A method for manufacturing the cell culturing article, a method for culturing undifferentiated stem cells and a method for regulating stem cell differentiation are also provided herein.

Abstract: A wringable mop includes a transmission unit mounted with a driven cap at the bottom side of an actuating sleeve that is rotatable and axially movable relative to the handle unit, a cleaning body connected between the handle unit and the driven cap, and a positioning unit controlling rotation and axial movement of the actuating sleeve relative to the handle unit. When the positioning unit controls one-way rotation of the actuating sleeve relative to the handle unit, the handle unit and the actuating sleeve are rotated relative to each other to cause rotation of the driven cap relative to the handle unit, and therefore the cleaning body is twisted.

Abstract: A mop includes a liquid absorbent member having two ends fastened respectively to a movable rigid member and a fixed rigid member, a rod body, a tubular actuator unit sleeved on the rod body, a tubular driven unit sleeved rotatably on the actuator unit, and an operation member sleeved on the driven unit. The fixed rigid member is anchored to the rod body. The movable rigid member is sleeved rotatably and movably on the rod body. A planetary gear mechanism is disposed between the driven unit and the movable rigid member for transferring rotation of the driven unit to the movable rigid member. To wring out the liquid in the liquid absorbent member, the operation member is moved on the driven unit so as to rotate the driven unit on the actuator unit, thereby rotating the movable rigid member relative to the fixed rigid member.
