Polyelectrolytes have many important functions in both living organisms and man-made applications. One key property of polyelectrolytes is the ionic conductivity due to their porous networks that allow transport water small molecular solutes. Among polyelectrolytes, zwitterionic polymers attracted huge attention for applications involve ion a polyelectrolyte matrix; however, it still unclear how functional groups polymer side chains affect swelling properties. In this study,...

Form-stable phase change materials (PCMs) are widely used for thermal management. However, the strong rigidity and weak photoabsorption ability have hindered their practical applications. Herein, we report a flexible PCM based on paraffin wax (PW) polydopamine-coated melamine foam (MF@PDA) seamlessly combined light-actuated shape memory light-to-thermal energy storage capability. The MF@PDA foams with different PDA contents, which act as supporting scaffolds to adsorb PW, successfully...

Gene therapy provides a number of potential treatments that could be applied in clinic to prevent deaths from cancer. However, the transfer gene clinical application has proven difficult because many problems remain solved concerning transfection efficiency, target specificity, and safety issues. To overcome these barriers, peptide-based vector, K(12)H(6)V(8)SSQHWSYKLRP (KHV-LHRH) comprises four functional blocks, is studied this work for targeted delivery model drug cancer cells. KHV-LHRH...

[reaction: see text] The synthesis of a variety unsaturated ethers, esters, and amides derived from urocanic acid their Diels-Alder reactions are reported. Propargylic ethers esters cyclize with reasonable efficiencies, but the related mono- unactivated olefins did not cyclize. On other hand, corresponding amines amides, along doubly activated ester/amide derivatives participate in cycloaddition reaction.
