1000 ) Ca 2 N surface

چکیده
Polymer diodes require cathodes that do not corrode the polymer but do have low work function to minimize the electron injection barrier. First-principles calculations demonstrate that the work function of the (1000) surface of the compound Ca 2 N is half an eV lower than that of the elemental metal Ca (2.35 vs. 2.87 eV). Moreover its reactivity is expected to be smaller. This makes Ca 2 N an interesting candidate to replace calcium as cathode material for polymer light emitting diode devices. [PACS: 73.30 +y]

بررسی میزان محدودیت پتاسیم قابل استفاده برای گندم در یک خاک لسی
The objective of this study was determining the most limiting plant growth factor in the wheat root zone dominated by illite in clay fraction and a high specific surface with ample ammonium acetate extractible potassium. A completely randomized block design with 4 replicates was used in Seyed Miran Research Farm (Gorgan) during 2009-2010 growing season. Treatments were mineral fertilizers (to a...
متن کاملMerging late Holocene molecular organic and foraminiferal‐based geochemical records of sea surface temperature in the Gulf of Mexico
[1] A molecular organic geochemical proxy (TEX86) for sea surface temperature (SST) is compared with a foraminifera‐based SST proxy (Mg/Ca) in a decadal‐resolution marine sedimentary record spanning the last 1000 years from the Gulf of Mexico. We assess the relative strengths of the organic and inorganic paleoceanographic techniques for reconstructing high‐resolution SST variability during rece...
متن کاملHigh surface area carbon aerogels as porous substrates for direct growth of carbon nanotubes.
Novel carbon composites are fabricated through catalyzed CVD growth of carbon nanotubes directly on the inner surfaces of monolithic carbon aerogel (CA) substrates. Uniform CNT yield is obtained throughout the internal pore volume of CA monoliths with macroscopic dimensions. These composites possess large surface areas (>1000 m(2) g(-1)) and exhibit enhanced electrical conductivity following CN...

ID No: 65 ABSTRACT This research studies the self-healing potential of early cracks in cement-based materials incorporating carbonic anhydrase (CA) bacteria. CA bacteria can accelerate the CO2 hydrated reaction then transfer CO2 to HCO3 which can react with soluble Ca(OH)2 on the surface of specimens. Calcium carbonate deposits because of the reaction of HCO3 with Ca.This research studies the s...
متن کاملIn vivo epithelial wound repair requires mobilization of endogenous intracellular and extracellular calcium.
We report that a localized intracellular and extracellular Ca(2+) mobilization occurs at the site of microscopic epithelial damage in vivo and is required to mediate tissue repair. Intravital confocal/two-photon microscopy continuously imaged the surgically exposed stomach mucosa of anesthetized mice while photodamage of gastric epithelial surface cells created a microscopic lesion that healed ...
