Low cost and high performance white polymer light-emitting diodes (PLEDs) are very important as solid-state lighting sources. In this research three commercially available phosphors were carefully chosen, bis[2-(4,6-difluorophenyl) pyridinato-N, C-2](picolinate) iridium(III) (FIrpic), bis[2-(2-pyridinyl-N) phenyl-C](2,4-pentanedionato-O-2, O-4) iridium(III) [Ir(ppy)(2)(acac)], and bis(2-phenyl-benzothiazole-C-2, N)(acetylacetonate) iridium(III) [Ir(bt)(2)(acac)], plus a home-made red phosphor of tris[1-(2,6-dimethylphenoxy)-4-(4-chlorophenyl)phthalazine]iridium(III) [Ir(MPCPPZ)(3)], and their photophysical and morphological properties were systematically studied as well as their applications in single-emission layer white PLEDs comprising poly(N-vinylcarbazole) as host. Additionally, the electrochemical properties and energy level alignment, possible energy transfer process, and thin-film morphology were also addressed. The binary blue/ orange complementary white PLEDs exhibit stable electroluminescence spectra, wide spectrum-covering region range from 380-780 nm, and high color rendering index (CRI) over 70 with Commission Internationale de l’Eclairage coordinates x, y (CIEx,y) of (0.388, 0.440), correlated color temperature (CCT) of around 4400, plus high efficiency of 25.5 cd A(-1). The optimized red-green-blue white PLEDs showed a satisfactory CRI of around 82.4, maximum current efficiency of 20.0 cd A(-1) and external quantum efficiency (EQE) of 10.8%, corresponding to a CCT of 3700-2800, which is a warm-white hue. At last, stable and high color quality, red-green-orange-blue four component white PLEDs, with a CRI of over 82, a high efficiency of 24.0 cd A(-1), EQE of 11.5%, and high brightness of 43 569.9 cd m(-2) have been obtained.

In this study, propanedioic acid was investigated as a potential additive in poly(phthalazine ether sulfone ketone) (PPESK)/N-methyl-2-pyrrolidone solutions. Compared with poly(ethylene glycol) with a molecular weight of 1000 and Tween 80 as additives, different phenomena were observed: (1) both fingerlike and spongelike structures of asymmetric ultrafiltration membranes were induced by rapid gelation, and (2) a spongelike structure membrane with a high pure water flux was obtained under a high gelation rate. Moreover, the PPESK membrane formation process was recorded with a recently developed optical microscopy (OM)-charge-coupled device (CCD) camera experimental system. The predicted membrane structure with an OM-CCD system gave good correspondence with the final membrane structure and performance, as detected by scanning electron microscopy.

Computational techniques are widely used to reduce costs associated with new drug development with the ability to bind a specific molecular target. These studies need a Brookhaven protein data bank structure sample of the enzyme interaction with an inhibitor of adequate size. In this context, a new computational methodology is postulated to be used when there are no published samples fulfilling this requirements. In this study, 7 compounds, which showed anti-T. cruzi, L. donovani and L. infantum properties, and proved to be inhibitors of their Fe-SOD enzymes, have been theoretically evaluated against related parasites Fe-SOD enzymes, which have been proposed as targets for antiparasitic drugs. This methodology may be applied to similar cases and also to generate starting structures to be used with different CADD methods
