Abstract: The present invention provides a method for producing CAR T-cells enriched with stem cell-like memory T-cells (Tscm), comprised of: (1) providing PBMCs; (2) isolating of T cells from PBMCs using magnetic beads coated with T-cell specific antibodies; (3) positively selecting T cells by culturing them in the form of T cell-magnetic bead complexes; (4) adding CAR-expressing lentivirus to the activated human T cell-magnetic bead complexes, for transduction of human T cells into CAR-T cells on the human T cell-magnetic bead complexes to obtain human CAR-T cell-magnetic bead complexes; (5) obtaining human CAR-T cells by dissociating the human CAR-T cells from the human CAR-T cell-magnetic bead complexes; and (6) further culturing CAR-T cells to obtain CAR-T cells enriched with Tscm. The present invention expands T cells in a short period of time to obtain CAR-T cells enriched with Tscm, which is suitable for CAR-T immunotherapy.

Abstract: A method of forming low-k material is provided. The method includes providing a plurality of core-shell particles. The core of the core-shell particles has a first ceramic with a low melting point. The shell of the core-shell particles has a second ceramic with a low melting point and a low dielectric constant. The core-shell particles are sintered and molded to form a low-k material. The shell of the core-shell particles is connected to form a network structure of a microcrystal phase.

Abstract: An optical system affixed to an electronic apparatus is provided, including a first optical module, a second optical module, and a third optical module. The first optical module is configured to adjust the moving direction of a first light from a first moving direction to a second moving direction, wherein the first moving direction is not parallel to the second moving direction. The second optical module is configured to receive the first light moving in the second moving direction. The first light reaches the third optical module via the first optical module and the second optical module in sequence. The third optical module includes a first photoelectric converter configured to transform the first light into a first image signal.

Abstract: The present invention provides a microfluidic structure for sorting targeted substances. The microfluidic structure includes: an inlet portion having at least one fluid input port; an outlet portion having a plurality of fluid output ports; a first annular flow channel communicated with the inlet portion at the upstream end and rotatably extended; and a second annular flow channel communicated with the downstream end of the first annular flow channel at the upstream end, communicated with the outlet portion at the downstream end and rotatably extended. The first annular flow channel and the second annular flow channel are connected in series according to an S-shaped track, so that the outer side wall of the first annular flow channel is continuously connected to the inner side wall of the second annular flow channel. The cross-sections of the first annular flow channel and the second annular flow channel have a height difference.

Abstract: A halogen-free, phosphorus-free poly-cyclic compound is used a flame retardant. This compound has amide and hydroxy groups, and thus it is able to react with an epoxy resin to form a reactive type flame-retardant advanced epoxy resin. The advanced epoxy resin together with an inorganic additive are mixed with an epoxy resin to form a halogen-free, phosphorus-free flame-retardant epoxy composition, which can be used in the manufacture of a printed circuit board and as an encapsulation material for a semi-conductor device.
