Mechanism Study of the Polymerization of Polyamide 56: Reaction Kinetics and Process Parameters.

Polyamide 56 (PA56) has gained significant attention in the academic field due to its remarkable mechanical and thermal properties as a highly efficient and versatile biobased material. Its superior moisture absorption property also makes it a unique advantage in the realm of fiber textiles. However, despite extensive investigations on PA56's molecular and aggregate state structure, as well as processing modifications, little attention has been paid to its polymerization mechanism.

Synthesis of photothermal antimicrobial cotton gauze using AuNPs as photothermal transduction agents.

Cotton gauze has been used as a wound dressing since the 19th century, and still plays an important role in current clinical therapies. However, the antimicrobial ability of cotton gauze is limited. In this work, gold nanoparticles (AuNPs) were used as photothermal transduction agents to synthesize modified photothermal antimicrobial cotton gauze.

Synthesis and anti-tumor activities of novel oxazinyl isoflavonoids.

The design, synthesis and biological evaluation of a novel series of oxazinyl isoflavonoids is described. Several analogs were shown to exhibit growth inhibitory effects against SKOV-3, DU-145 and HL-60 human colon cancer cell lines with IC(50) values in the micromolar range. The cellular potency of compounds 7e and 12h were found to have greater in vitro inhibitory activities than phenoxodiol, the parental compound currently in late-stage clinical trials for the treatment of cancer.
