Thermoplastic starch (TPS) materials present several advantages to the plastic industry andwhen blended with other materials they can exhibit improved mechanical and moisturesensitivity properties compared to pure TPS materials. Further investigations on TPS: PVAblends are of particular interest due to their excellent compatibility and improved properties suchas tensile strength, elongation, to...

Nanofibrous scaffolds produced by electrospinning have attracted much attention, recently. Aligned and random nanofibrous scaffolds of poly (vinyl alcohol) (PVA), poly (ε-caprolactone) (PCL) and nanohydroxyapatite  (nHA) were fabricated by electrospinning method in this study. The composite nanofibrous scaffolds were subjected to detailed analysis. Morphological investigations revealed that the...

The post-functionalization of poly(3-hexylthiophene) (P3HT) via various synthetic routes is reported. Well-defined and monofunctionalized ω-thiol-terminated P3HT, ω-carboxylic acid-terminated P3HT, ω-acrylate-terminated P3HT, and ω-methacrylate-terminated P3HT are obtained in high yields through a straightforward procedure. From those, different novel P3HT-based graft copolymers are synthesized...

Hydrogels In article number 2213382, Soo-Jin Park, Insik In, Dong-Yeun Koh, Albert S. Lee, and co-workers propose, catechol-functionalized poly(vinyl alcohol)-based hydrogel to inhibit the oxidation of MXene nanofiller while maintaining excellent mechanical electrical properties suitable for strain sensors. Sufficient interaction hydrophobic catechol groups with surface reduces oxidation-access...

Poly(vinyl acetate)-b-polystyrene, poly(vinyl acetate)-b-poly(methyl acrylate) and poly(vinyl acetate)-b-poly(methyl methacrylate) block copolymers with low polydispersity (M(w)/M(n) < 1.25) were prepared by successive reversible addition-fragmentation chain transfer (RAFT) polymerization and atom transfer radical polymerization (ATRP) employing a bromoxanthate iniferter (initiator-transfer age...

Background & Aims: Cancer immunotherapy, despite its many benefits, faces major challenges. Nanoparticles are drug delivery systems that may address these challenges. The goal of this study was to produce the tumor cell lysate and Poly-IC loaded nanoparticles with desirable properties and evaluation of their therapeutic effects in mouse model of breast cancer. Materials & Methods: Nanoparticle...
