Direct sulfonation and photocrosslinking of unsaturated poly(styrene-b-butadiene-b-styrene) for proton exchange membrane of direct methanol fuel cell
TL;DR: In this paper, a simple preparation of partially sulfonated poly(styrene-b-butadiene)-b-styrene) (sSBS), casting and photocrosslinking of tough films which can be used as a proton exchange membrane (PEM) for direct methanol fuel cell (DMFC) was demonstrated.

Solution processed thin films of Nb-doped TiO2 nanoparticles as hole blocking layer for organic solar cells
TL;DR: In this paper, Nb-doped TiO 2 nanoparticles were synthesized by sol-gel method with controlled doping ratios up to 6.5 moles by using p -toluene sulfonic acid.

Seung Chul Gil,Jin Chul Kim,Dahee Ahn,Jin-Sung Jang,Haekyoung Kim,Jin Chul Jung,Seongyop Lim,Doo-Hwan Jung,Wonmok Lee +8 more
TL;DR: Sulfonated polyethersulfones (sPES) with thermally crosslinkable allyl or propargyl end groups were synthesized and evaluated as methanol-tolerant proton exchange membranes (PEMs) for use in a direct methanoline fuel cell (DMFC) as discussed by the authors.
