This study demonstrates a simple and highly reproducible method for fabricating well-defined nanostructured polymeric surfaces with aligned nanoembosses or nanofibers of controllable aspect ratios, showing remarkable structural similarity with interesting natural biostructures such as the wing surface of Cicada orni and the leaf surface of Lotus. Our studies on the present biomimetic surfaces r...

Graphitic carbon nitride, a polymeric catalyst, was immobilized on the surfaces of chemically converted graphene sheets to form a layered composite, which exhibited greatly improved conductivity and electrocatalytic performance on oxygen reduction reaction.

due to unique applications of palladium nanoparticles, synthesis of these nanoparticles by a simple andlow cost method is very important. in this work, pd nanoparticles were synthesized with narrow sizedistribution by loading metal salt (pd(oac)2 ) into the polymeric matrix (peg) as reducing agent andstabilizer. also, the effect of metal salt concentration and peg molecular weight on the conver...

Protein delivery across polarized epithelia is controlled by receptor-mediated transcytosis. Many studies have examined basolateral-to-apical trafficking of polymeric IgA (pIgA) by the polymeric immunoglobulin receptor (pIgR). Less is known about apical-to-basolateral transcytosis, the direction the neonatal Fc receptor (FcRn) transports maternal IgGs across intestinal epithelia. To compare api...

Printed, flexible, and hybrid electronic technologies are advancing rapidly leading to remarkable developments in smart wearables, intelligent textiles, health monitoring systems. Flexible electronics typically fabricated on petroleum-derived polymeric substrates. However, the light of global environmental concerns regarding fossil raw materials, there is a need drive production flexible device...

preparation and uses of quinaldinium dichromate and its polymeric analogue poly (2- vinylquinolinium) dichromate as the new monomeric and polymeric oxochromium-amine complex reagents for oxidizing variousorganic compounds, with emphasis on the latter, are described

Herein we report preparation of polymeric monofunctional nanoparticles (PMNs) through intramolecularly cross-linking the polymer chains sparsely grafted on the surface of sacrificial silica spheres, and a one-to-one coupling reaction between PMNs and linear polymer chains and that between two PMNs.

Recent investigations on the coalescence of polymeric droplets a solid substrate have reported strong disagreements; heart issue is whether drops similar to that Newtonian fluid and independent molecular relaxation, or role entanglement chains leads transition kinetics different from fluid. Via this report, we resolve disagreements through discussion effects merging method dominant forces gover...
