  • Publication number: 20200362389
    Abstract: The present invention provides a DNA barcode and method for identifying cuttlefishes, mainly depending on the diversity of mitochondrial DNA, including designing universal primers on conservative regions on both sides of the species-specific variable region, amplifying DNA from cuttlefishes, and sequencing PCR products to obtain DNA sequences, and identifying cuttlefish species based on the similarity by comparing with the species information in the database. The method is advantageous in that it can achieve efficient and specific amplification of DNA from such cephalopods as cuttlefishes, with low requirements for necessary instruments and simple operation processes. In addition, the method can be carried out in most molecular biology laboratories, which greatly improves the probability of success of molecular identification for cuttlefishes and sibling species thereof.

  • Publication number: 20200283573
    Abstract: A flame-retardant polyether polyol is provided, including a Mannich base and an epoxide. The epoxide is selected from ethylene oxide, propylene oxide and butylene oxide. The Mannich base has a structure represented by a formula (I). In the Mannich base, flame-retardant groups, i.e., halogens are introduced at the second, fourth and sixth positions of a phenyl group, and flame-retardant elements, i.e., halogens and nitrogen are introduced into synthesized polyether polyol. The amount of active hydrogen in the Mannich base is small so that side reactions during synthesis of the polyether polyol are reduced, and the viscosity of the polyether polyol is lowered. A flame-retardant polyurethane material is also provided, synthesized from raw materials comprising the above-mentioned flame-retardant polyether polyol and an isocyanate. Due to autocatalytic performance of tertiary amido in the flame-retardant polyether polyol, use of a catalyst can be reduced and even avoided during the synthesis.
