Abstract: The present invention provides a “living” radical polymerization method for a vinyl monomer by near-infrared photothermal conversion. The method comprises irradiating a reactor with near-infrared light of 750-850 nm, wherein the reactor has a first chamber and a second chamber that are isolated from each other, the first chamber contains an organic solution of a near-infrared light responsive croconaine dye, and the second chamber is provided with a closed reaction flask containing a reaction solution, the reaction solution comprises a vinyl monomer, two or more of an ATRP initiator, an ATRP ligand, an ATRP catalyst, an RAFT reagent, a thermal initiator, and an additive, and an organic solvent; and the near-infrared light responsive dye converts the near-infrared light into heat energy, by which the reactor is heated to 50-100° C. to polymerize the monomer in the reaction solution, to obtain polymers with controlled molecular weights and molecular weight distributions.

Abstract: This application proposes a polyamide-imide copolymer film and a flexible display. The polyamide-imide copolymer film is obtained by copolymerizing aromatic dianhydride and aromatic dicarbonyl compound with aromatic diamine. Wherein, the aromatic dicarbonyl compounds include fluorinated aromatic dicarbonyl compound and non-fluorinated aromatic dicarbonyl compound. The polyamide-imide copolymer film can obtain a very low yellow degree index and dual refractive index, which is suitable for the substrate production of flexible display.

Abstract: Recombinant microbial cells are disclosed herein that produce an oil comprising at least 28 percent eicosapentaenoic acid (EPA) measured as a weight percent of dry cell weight. These cells may comprise a polynucleotide sequence encoding an active acyl-CoA:lysophosphatidylcholine acyltransferase (LPCAT) comprising at least one amino acid mutation in a membrane-bound O-acyltransferase motif. In addition, the cells may comprise a down-regulation of an endogenous polynucleotide sequence encoding Sou2 sorbitol utilization protein, and/or one or more polynucleotides encoding phospholipid:diacylglycerol acyltransferase (PDAT), delta-12 desaturase, a dihomo-gamma-linolenic acid (DGLA) synthase multizyme, delta-8 desaturase, malonyl-CoA synthetase (MCS), or acyl-CoA:lysophosphatidic acid acyltransferase (LPAAT).
