The scarcity of fossil fuels calls for immediate action toward the development clean and renewable energy resources. In this context, proton exchange membrane fuel cells (PEMFCs) are gaining ever-increasing attention as technology. Although covalent organic frameworks (COFs) do not usually exhibit high intrinsic conductivity (σ), they have been recently proposed solid polymer electrolytes in PE...

This study explores a binary solvent system composed of biobased Cyrene and its derivative Cygnet 0.0 for application in membrane technology biocatalytic synthesis polyesters. Cygnet-Cyrene blends could represent viable replacements toxic polar aprotic solvents. The use 50 wt % mixture makes practical difference the production flat sheet membranes by nonsolvent-induced phase separation. New pol...

Homogeneous membranes were prepared by blending poly (acrylic acid) with poly (vinyl alcohol). These blend membranes were evaluated for the selective separation of alcohols from toluene by pervaporation. The flux and selectivity of the membranes were determined both as a function of the blend composition and of the feed mixture composition. The results showed that a polymer blending method coul...

Neural responses to odor blends often exhibit non-linear interactions to blend components. The first olfactory processing center in insects, the antennal lobe (AL), exhibits a complex network connectivity. We attempt to determine if non-linear blend interactions can arise purely as a function of the AL network connectivity itself, without necessitating additional factors such as competitive lig...

A stimuli-responsive poly(vinyl alcohol) (PVA)/sodium alginate (SA) blend monolith with nanoscale porous (mesoporous) structure is successfully fabricated by thermally impacted non-solvent induced phase separation (TINIPS) method. The PVA/SA blend monolith with different SA contents is conveniently fabricated in an aqueous methanol without any templates. The solvent suitable for the fabrication...

Tetrafunctional multigraft copolymers based on polyisoprene and polystyrene were prepared by an upscalable pilot-scale anionic synthesis approach, prospectively making this new type of thermoplastic elastomers available for future industrial applications. The materials characterized with respect to their molecular architecture, microphase-separated morphology, thermal mechanical properties unde...

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...
