Studies on the SPEEK membrane with low degree of sulfonation as a stable proton exchange membrane for fuel cell applications
Sulfonated poly (ether ether ketone) (SPEEK) with a low degree of sulfonation (DS = 40%) was prepared for proton exchange membrane fuel cells (PEMFC). Poly (ether ether ketone) (PEEK) was sulfonated in concentrated H2SO4 under N2 atmosphere and characterized by the hydrogen nuclear magnetic resonance (H-NMR) technique. After preparation of the SPEEK polymer, the obtained polymer was dissolved i...
متن کاملOptical amplifier for space applications.
We describe an optical amplifier designed to amplify a spatially sampled component of an optical wavefront to kilowatt average power. The goal is means for implementing a strategy of spatially segmenting a large aperture wavefront, amplifying the individual segments, maintaining the phase coherence of the segments by active means, and imaging the resultant amplified coherent field. Applications...
متن کاملPotential Use of Amniotic Membrane Derived Scaffold for Cerebrospinal Fluid Applications
Scaffolds derived from decellularized tissues provide a natural microenvironment for cell culture. Embryonic cerebrospinal fluid (e-CSF) contains factors which play vital roles in development of the nervous system. This research was aimed to survey the effect of Wistar rat e-CSF on neural differentiation of bone marrow derived mesenchymal stem cells (BM-MSCs) cultured on the human amniotic memb...
متن کاملMembrane Biological Reactors (MBR) and Their Applications for Water Reuse
The term 'membrane bioreactor' expresses a combination of activated sludge and membrane separation processes. The need to processes like sedimentation and disinfection used in common methods is eliminated through MBR systems in a way that membranes are placed into or out of an aeration tank and the vacuumed wastewater created by the suction pump is pulled up from inside the membranes and leaves...
