A colloidal synthesis approach is presented that allows systematic studies of the properties of supported proton exchange membrane fuel cell (PEMFC) catalysts. The applied synthesis route is based on the preparation of monodisperse nanoparticles in the absence of strong binding organic stabilizing agents. No temperature post-treatment of the catalyst is…

Self-assembled ?cross? architectures are well-known in biological systems (as illustrated by chromosomes, for example); however, comparable synthetic structures are extremely rare. Herein we report an in depth study of the hierarchical assembly of the amphiphilic cylindrical P?H?P triblock comicelles with polar (P) coronal ends and a hydrophobic (H) central periphery…

The formation of self-assembled structures is of great interest in the field of ferroelectric (FE)–ferromagnetic (FM) oxide interfaces with novel functionalities driven by the combination of strain relaxation and diffusion/segregation processes occurring during epitaxial growth of Mn-based heterostructures. In epitaxial bilayers and multilayers of La0.67Sr0.33MnO3 (LSMO)/BaTiO3 (BTO) on (001)…

Small angle X-ray (SAXS) and neutron scattering techniques were combined to study mixed complexes formed between micelles of the nonionic amphiphilic PEO-PPO-PEO copolymer (P123) and the anionic bile salt (NaGDC) in aqueous solution. The purpose was to investigate the structural parameters of the charged complexes, such as size and internal…

We have characterized the dissolved state of microcrystalline cellulose (MCC) in cold alkali solutions using a combination of small angle X-ray (SAXS) and static light scattering (SLS), 11^1H NMR, NMR self-diffusion, and rheology experiments. NMR and SAXS data demonstrate that the cellulose is fully molecularly dissolved. SLS, however, shows the…

Single-step electrospinning of micro-fibers from native solutions of poly(3-octyl thiophene) (P3OT) presents a simplified processes as compared to previously reported host-guest or core–shell strategies for production of conjugated-polymers fibers. Furthermore, as P3OT is a good dispersing agent for Multi-Walled Carbon Nanotubes (MWNT) the process is extended to spinning of MWNT-P3OT…

The performance of organic solar cells is determined by the delicate, meticulously optimized bulk-heterojunction microstructure, which consists of finely mixed and relatively separated donor/acceptor regions. Here we demonstrate an abnormal strong burn-in degradation in highly efficient polymer solar cells caused by spinodal demixing of the donor and acceptor phases, which…
