We developed two types of in-situ three-dimensional imaging systems on the basis of full-field transmission X-ray computed tomography (XCT) methods for polymer electrolyte fuel cells (PEFCs) under operating conditions at beamline BL36XU at SPring-8. One was for a wide field of view (more than 500 μm) to obtain the whole membrane electrode assembly (MEA) images, and the other was for nano spatia...

Triprolidine (Trip) ion selective electrodes of three types: the conventional polymer membrane (I), graphite coated electrode (II) and carbon paste electrode (III), have been prepared, based on the ion pair of triprolidine hydrochloride with sodium tetraphenylborate. The electrodes exhibit a linear response with a mean calibration graph slope of 56.12, 55.00 and 54.32 mV decade(-1) at 25 degree...

As the global energy demand continues to increase, interest in photosynthetic conversion is growing accordingly. Chloroplasts, organelles present plants and algae, are attractive candidates for construction of bio solar cells; however, they have been less studied because their complex membrane system, which restricts electrochemical communication with an electrode surface. Nevertheless, this wo...

A new sensor constructed by a platinum electrode coated with a non-plasticized poly(acrylamide) polymer (PAA) film coupled with phthalocyaninato tin(II) ([Sn(II)(pc)]) was developed. The potentiometric response behavior of this PAA-[Sn(II)(pc)] electrode for such anions as CN-, F-, Cl-, and Br- in dimethylacetamide and acetonitrile were investigated. The electrode showed a Nernstian response to...

We report on ITO-free large-area organic light-emitting diodes (OLEDs) fabricated on glass substrates comprising α-NPD as a hole transport layer (HTL) and coevaporated CBP:Ir(ppy)(3) as the emission layer. Indium-tin-oxide (ITO) was replaced with a conductive polymer electrode and an electroplated thick metal grid was used to improve the homogeneity of the potential distribution over the transp...

Blend reverse osmosis membranes were fabricated using polyvinyl chloride (PVC) with cellulose acetate (CA) as polymer blends. Tetrahydrofuran (THF) and N-Methyl-2-pyrrolidone (NMP) were used as solvents. The membrane polymer solution was cast on a coated woven fabric support material. The prepared membranes have been characterized by SEM and mechanical properties. SEM r...

A PVC membrane Fe(III) ion selective electrode has been constructed using a new macrocyclic asmembrane carrier.The electrode exhibits a good potentiometric response for Fe(III) over a wideconcentration range 1.0×10-4 to 1.0×10-1M with a slope 19.4±0.5 mV/decade a and a working pHrange of 6.5-9.0. It has a fast response time ≤30s.The best performance was observed with themembrance having the 30....
