In the present study, catalytic activity of dense, porous, electrospun membranes polysulfone (PSF) and with sulfonated polystyrene (PSF_PSS) have been evaluated in reactions esterification oleic acid methanol, times that varied from 10 to 480 minutes. Conversion biodiesel has confirmed by FTIR quantified through gas chromatography. The results showed catalysts used were effective reaction studi...

A novel proton exchange membrane has been prepared using sulfonated poly(styrene-divinylbenzene) resin(SPSDR)–polyethylene(PE). The membrane is characterized by FT-IR, SEM and TGA/DSC. Water uptake, oxidative resistance, ionic conductivity and methanol permeability are measured to evaluate its performance in a direct methanol fuel cell. The on-set degradation temp...

Sulfonated polyelectrolyte membranes (PEMs), such as Nafion and styrene-olefin block copolymers, are explored as permselective membranes for fuel cells as well as suitable barrier materials against chemical agents. The permselective properties of PEM are determined by their microphase segregation into hydrophilic and hydrophobic domains. We performed classical molecular dynamics simulations of ...

A straightforward method is presented for the preparation of nano- to micrometer-sized Janus discs with controlled shape, size, and aspect ratio. The relies on cross-linkable ABC triblock terpolymers involves first prolate ellipsoidal microparticles by combining Shirasu porous glass (SPG) membrane emulsification evaporation-induced confinement assembly (EICA). By varying pore diameter SPG membr...
