Polarized micro-cavity organic light-emitting devices.

December 21, 2009 2:37 pm | by Opt Express | Articles | Comments

We present the results of a study of light emissions from a polarized micro-cavity Organic Light-Emitting Device (OLED), which consisted of a flexible, anisotropic one-dimensional (1-D) photonic crystal (PC) film substrate. It is shown that luminous Electroluminescent (EL)...

Exceptionally efficient organic light emitting devices using high refractive index substrates.

December 21, 2009 2:37 pm | by Opt Express | Articles | Comments

Organic light emitting devices (OLEDs) are now used in commercial cell phones and flat screen displays, but may become even more successful in lighting applications, in which large area, high efficiency, long lifetime and low cost are essential. Due to the relatively high...

Absorption and quasiguided mode analysis of organic solar cells with photonic crystal photoactive layers.

December 21, 2009 2:37 pm | by Opt Express | Articles | Comments

We analyze optical absorption enhancements and quasiguided mode properties of organic solar cells with highly ordered nanostructured photoactive layers comprised of the bulk heterojunction blend, poly-3-hexylthiophene/[6,6]-phenyl-C61-butyric acid methyl ester (P3HT:PCBM) and a...

Thermodynamics of hydrogen adsorption in MOF-177 at low temperatures: measurements and modelling.

December 21, 2009 2:37 pm | by Nanotechnology | Articles | Comments

Hydrogen adsorption measurements and modelling for the Zn-based microporous metal-organic framework (MOF) Zn4O(1,3,5-benzenetribenzoate)2, MOF-177, were performed over the 50-77 K and 0-40 bar ranges. The maximum excess adsorption measured under these conditions varies over...

Mechanisms of synergistic skin penetration by sonophoresis and iontophoresis.

December 21, 2009 2:37 pm | by Biol Pharm Bull | Articles | Comments

The mechanism of skin penetration enhancement by ultrasound under sonophoresis (US) or by an electrical field under iontophoresis (IP) was investigated using hairless mouse skin in vitro. The seven model chemicals with different molecular weights (122-1485) were dissolved in a...

Acoustic cavitation as an enhancing mechanism of low-frequency sonophoresis for transdermal drug delivery.

December 21, 2009 2:37 pm | by Biol Pharm Bull | Articles | Comments

We investigated the role of acoustic cavitation on sonophoretic skin permeation of calcein, a model permeant, across excised hairless rat skin. Three different frequencies (41, 158, 445 kHz) and various intensities (60 to 300 mW/cm(2)) of ultrasound were applied. Cavitation...

Ribonucleoprotein dynamics connects mRNA networks with drug mechanisms

December 21, 2009 2:37 pm | Articles | Comments

Beyond transcription, gene expression is potently controlled through processes that affect pre-mRNA splicing and maturation, as well as mRNA transport, turnover, storage, and translation. These events are tightly regulated by two main classes of trans-binding factors,...

Educational intervention to improve physician reporting of adverse drug reactions (ADRs) in a primary care setting in complementary and alternative medicine.

December 21, 2009 2:37 pm | by BMC Public Health | Articles | Comments

BACKGROUND: Recent studies have shown that adverse drug reactions (ADRs) are underreported. This may be particularly true of ADRs associated with complementary and alternative medicine (CAM). Data on CAM-related ADRs, however, are sparse.Objective was to evaluate the impact of...

Report: NM greenhouse gas emissions are up

December 21, 2009 2:12 pm | by SUSAN MONTOYA BRYAN - Associated Press Writer - Associated Press | News | Comments

An inventory of New Mexico's greenhouse gas production shows residents have reduced their average emissions from gasoline use over a seven-year period, but they're consuming more energy to heat, cool and power their homes.Despite efforts by Gov. Bill Richardson's administration to address...

First Solar eyes Blanquefort for French plant

December 21, 2009 1:28 pm | by Reuters | News | Comments

NEW YORK (Reuters) - Solar module maker First Solar Inc said it and partner EDF Energies Nouvelles were in the final stages of talks to build a new manufacturing plant in Blanquefort, France.

U.S. cap and trade looks out of reach in 2010

December 21, 2009 1:28 pm | by Reuters | News | Comments

WASHINGTON (Reuters) - U.S. lawmakers face an uphill battle enacting a climate bill in 2010 that includes a cap-and-trade market in greenhouse gases, after this month's U.N. meeting in Copenhagen failed to hammer out a global pact on emissions cuts.
