Unbroken Perovskite: Interplay of Morphology, Electro-optical Properties, and Ionic Movement

May 26, 2016 | Sin categoría

Hybrid organic–inorganic perovskite materials have risen up as leading components for light harvesting applications. However, to date many questions are still open concerning the operation of perovskite solar cells (PSCs). A systematic analysis of the interplay among...

Efficient bifacial dye-sensitized solar cells through disorder by design

Abr 26, 2016 | Sin categoría

Herein we realize an optical design that optimizes the performance of bifacial solar cells without modifyingany of the usually employed components. In order to do so, dielectric scatterers of controlled size andshape have been successfully integrated in the working...

Trans-oligomerization of duplicated aminoacyl-tRNA synthetases maintains genetic code fidelity under stress

Mar 26, 2016 | Sin categoría

Aminoacyl-tRNA synthetases (aaRSs) play a key role in deciphering the genetic message by producing charged tRNAs and are equipped with proofreading mechanisms to ensure correct pairing of tRNAs with their cognate amino acid. Duplicated aaRSs are very frequent in...

O2-assisted Water Gas Shift reaction over structured Au and Pt catalyst

Feb 26, 2016 | 2016, 2016, 2016, 2016, 2016

Platinum and gold structured catalysts were compared as active phases in classical and O2-assisted WaterGas Shift (WGS) reaction. Both metals were supported on iron-doped ceria mixed oxide and then, struc-tured on metallic micromonolithic devices. As expected the WGS...

Optofluidic Modulation of Self-Associated Nanostructural Units Forming Planar Bragg Microcavities

Ene 26, 2016 | Sin categoría

Bragg microcavities (BMs) formed by the successive stacking of nanocolumnar porous SiO2 and TiO2 layers with slanted, zigzag, chiral, and vertical configurations are prepared by physical vapor deposition at oblique angles while azimuthally varying the substrate...
