Trap densities in amorphous-InGaZnO4 (α-IGZO) are extracted directly from the capacitance-voltage characteristics of thin-film transistors at low frequencies. It is found that trap flat energy gap, and 1.7×1016cm−3eV−1 deep far conduction band edge (Ec), but become larger near Ec. Moreover, postannealing reduces density Ec, which associated with reduction hysteresis current-voltage characteristics. The annealed α-IGZO does not have a Gaussian-type state has fewer tail states than amorphous Si.
BF2 complexes of aryl-substituted dipyrrolyldiketones (3a−c, 5a−d) have been synthesized by the condensation arylpyrroles obtained Suzuki cross-coupling reactions with malonyl chloride, followed treatment BF3·OEt2. The binding constants (Ka11) (3a−c) for various anions (Cl-, Br-, CH3CO2-, H2PO4-, and HSO4-) in CH2Cl2 decrease order Ph (3a) > o-tolyl (3b) 2,6-Me2Ph (3c), possibly because differences planarity number interacting o-CH units at sites. Aryl-substituted receptors exhibit a [1+1]...
Illuminating! Isolation of a π-core by covalently attached flexible hydrocarbon chains has been employed to synthesize blue-emitting oligo(p-phenylenevinylene) (OPV) liquids with tunable viscosity and optical properties. A solvent-free, stable, white-light emitting ink/paint, which can be applied onto various surfaces even LEDs, was made blending liquid OPVs emissive solid dopants.
Nonvolatile room-temperature luminescent molecular liquids are a new generation of organic soft materials. They possess high stability, versatile optical properties, solvent-free fluid behaviour and can effectively accommodate dopant dye molecules. Here we introduce an approach to optimize anthracene-based liquid materials, focussing on enhanced fluorescence quantum yield, colour tunability processability, with view flexible electronic applications. Enveloping the anthracene core in...
The extinct p-process nuclide 146Sm serves as an astrophysical and geochemical chronometer through measurements of isotopic anomalies its alpha-decay daughter 142Nd. Based on analyses 146Sm/147Sm alpha-activity atom ratios, we determined the half-life to be 68 \pm 7 (1sigma) million years (Ma), which is shorter than currently used value 103 5 Ma. This implies a higher initial abundance in early solar system, (146Sm/144Sm_0 = 0.0094\pm0.0005 (2sigma), previously estimated. Terrestrial, Lunar...

Phenylethynyl-bridged dipyrrin "dimers" have performed ZnII complexation to give coordination polymers, which provided the fluorescent colloidal spherical objects in solution as well on substrate according spacer units. Using a mixture of THF and water, unique morphologies, such bell-shaped "golf ball"-like architectures, were observed.
Dimensionally controlled and hierarchically assembled supramolecular architectures in nano/micro/bulk length scales are formed by self-organization of alkyl-conjugated fullerenes. The simple molecular design covalently attaching hydrophobic long alkyl chains to fullerene (C60) is different from the conventional (hydrophobic–hydrophilic) amphiphilic designs. two units C60 incompatible but both soluble organic solvents. van der Waals intermolecular forces among hydrocarbon π–π interaction...
The water flea Daphnia magna has been used as an animal model in ecology, evolution, and environmental sciences. Thanks to the recent progress genomics, genetic information such draft genome sequence expressed tags (ESTs) is now available. To investigate relationship between phenotypes available about Daphnia, some gene manipulation methods have developed. However, a technique induce targeted mutagenesis into remains elusive. overcome this problem, we focused on emerging editing mediated by...

In this context, we the room-temperature phosphorescence features of solvent-free organic liquid phosphor in air. While alkyl chain substitution varied physical states bromonaphthalimides, remained unaltered As first report, long swallow-tailed bromonaphthalimide exhibits Doping carbonyl guests resulted phosphorescence, and hence large-area...
Cancer-associated fibroblasts (CAFs) in the tumor microenvironment are involved progression of various cancers, including esophageal squamous cell carcinoma (ESCC). CAF-like cells were generated through direct co-culture human bone marrow-derived mesenchymal stem (MSCs), one CAF origins, with ESCC cells, and periostin was found to be highly expressed cells. After co-culture, showed increased malignant phenotypes such as survival, growth, migration, well phosphorylation Akt Erk. Recombinant...

Room temperature liquid C60 derivatives bearing a 2,4,6-trialkyloxyphenyl branch show dramatic decrease in viscosity with an increase the length of alkyl chains. This feature, when combined electrochemical activities similar to those pristine and relatively high charge carrier mobility, makes them extremely attractive novel carbon material for future applications materials science.
Fullerene derivatives bearing long alkyl chains epitaxially adsorb on the basal plane of graphite forming well-ordered one-dimensional lamellae. Within lamellae, C60 moieties are organized in a zigzag-type fashion. The ordering is mainly governed by substitution pattern and chain length chains. electrochemical activity groups fully maintained surface-confined assemblies.
