Abstract: This disclosure provides modified T cells possessing both cell killing function and antigen presenting cell function and method of culturing the same. By administration of the modified T cell, cancer cells in a subject may be effectively inhibited via cell-mediated immunity.

Abstract: A staining kit is provided, including a first pattern including antibodies against T cell, B cell, NK cell, monocyte, regulatory cell, CD8, CD45, and CTLA4; a second pattern including antibodies against T cell, B cell, NK cell, monocyte, regulatory cell, dendritic cell, and CD45; a third pattern including antibodies against T cell, B cell, NK cell, monocyte, CD8, CD45, CD45RA, CD62L, CD197, CX3CR1 and TCR??; and a fourth pattern including antibodies against B cell, CD23, CD38, CD40, CD45 and IgM, wherein the antibodies of each pattern are labeled with fluorescent dyes. A method of identifying characterized immune cell subsets of a disease and a method of predicting the likelihood of NPC in a subject in the need thereof using the staining kit are also provided.

Abstract: The disclosure relates to a fuel cell, a bipolar plate and a bipolar plate assembly for a fuel cell. The bipolar plate comprises: at least one distributing region; at least one first through hole which communicates with the distributing region via a circumferential opening on a sidewall as an inlet of a first reactant; and at least one second through hole which communicates with the distributing region via a circumferential opening on a sidewall as an outlet of a first reactant. Each of the at least one first through hole and the at least one second through hole has a cross section of approximately trapezoid with an arc edge or an oblique edge, and the circumferential opening is formed on a curved sidewall or on an oblique sidewall. The fuel cell has improved structural design of the bipolar plate to improve flow uniformity and hydrothermal management of the fuel cell.

Abstract: A method for making lithium cobalt oxide requires a cobalt salt solution and an alkaline solution as reactants, these reactants being put into a controlled crystallization reactor containing a buffer agent. The reactants are stirred to form spheres of cobalt oxyhydroxide. The spherical cobalt oxyhydroxide is put into a lithium hydroxide solution to have a hydrothermal reaction in a hydrothermal reactor to replace the hydrogen in cobalt oxyhydroxide with the lithium in lithium hydroxide, to form a product of spheres.

Abstract: A method for making a spherical cobalt oxyhydroxide requires a controlled crystallization reactor. A buffer agent is put into the controlled crystallization reactor. The buffer agent is capable of controlling a reacting speed of reactants. A cobalt salt solution and an alkaline solution as the reactants are added into the buffer agent in the controlled crystallization reactor. The reactants react together in a controlled crystallization method, the reactants being agitated only at a bottom region of the container of the controlled crystallization reactor.

Abstract: A method for making lithium iron phosphate is provided. In the method, an alkali is reacted with a ferric salt in water to form a red colored ferric hydroxide precipitate in the water. The red colored ferric hydroxide precipitate is mixed with deionized water, organic solvent, and emulsifier to form an water-in-oil emulsion. The phosphoric acid solution and iron metal powder are added to the water-in-oil emulsion to form ferrous hydrogen phosphate. A lithium source is introduced to the water-in-oil emulsion and reacted with the ferrous hydrogen phosphate to form a precursor in the water-in-oil emulsion. The precursor is heated in a protective gas at a heating temperature in a range from about 600° C. to about 800° C. to form lithium iron phosphate.
