The templated self-assembly of block copolymer (BCP) thin films can generate regular arrays of 10-50 nm scale features with good positional and orientational accuracy, but the ordering, registration and pattern transfer of sub-10-nm feature sizes is not well established. Here, we report solvent-annealing and templating methods that enable the formation of highly ordered grating patterns with a ...

Gelation kinetics and rheological properties of poly(vinylidene fluoride-co-hexafluoropropylene) [P(VDF-co-HFP)] solutions in methyl-ethyl-ketone 2-heptanone are investigated. Small-angle X-ray scattering measurements indicate that the systems undergo phase separation by a nucleation process. For concentrations between 6 10 wt% copolymer, strain-hardening appears when gels sheared nonlinear reg...

The electromagnetic interface shielding properties of poly(methyl-methacrylate) based composite materials filled with hybrid silver-coated glass microfibers are investigated between 100 kHz and 1 GHz using the coaxial cell method. incorporation ionic liquid EMPy-TFSI (1-ethyl-4-methylpyridinium bis(trifluoromethylsulfonyl)) into material leads to a substantial decrease in percolation threshold ...

The current study aimed to develop an anaerobic wastewater treatment and reuse module enabled by thermophilic bioprocessing, a microbial fuel cell (MFC) ultrafiltration (UF) treatment. A previously unexplored consortium based on Thermoanaerobacterium thermosaccharolyticum Arcobacter sp. was used remove ~73% of chemical oxygen demand (COD) from under conditions (CODi = 200 mg/L). subsequent MFC ...

Waveguides made of poly-methyl-methacrylate (PMMA) play a major role in the homogeneous distribution of display backlights as a matrix for solid-state dye lasers and polymer optical fibers (POFs). PMMA is favored because of its transparency in the visible spectrum, low price, and well-controlled processability. Nevertheless, technical drawbacks, such as its limited temperature stability, call f...
