On the different sources of cooperativity in pH titrating sites of a membrane protein channel
(EDP SciencesSocietà Italiana di FisicaSpringer-Verlag, 2016)
Cooperative interactions play a central role in the regulation of protein functions. Here we show that in multi-site systems like ion channels the application of the Hill formalism could require a combination of different ...
Band Engineering in Core/Shell ZnTe/CdSe for Photovoltage and Efficiency Enhancement in Exciplex Quantum Dot Sensitized Solar Cells
(ACS Publications, 2015-01-06)
Even though previously reported CdTe/CdSe type-II core/shell QD sensitizers possess intrinsic superior optoelectronic properties (such as wide absorption range, fast charge separation, and slow charge recombination) in ...
Understanding the Role of Underlayers and Overlayers in Thin Film Hematite Photoanodes
(Wiley, 2014-12-23)
Recent research on photoanodes for photoelectrochemical water splitting has introduced the concept of under- and overlayers for the activation of ultrathin hematite films. Their effects on the photocatalytic behavior were ...
Light-modulated TiOx Interlayer Dipole and Contact Activation in Organic Solar Cell Cathodes
(Wiley, 2014-10-22)
Understanding working mechanisms of selective interfacial layers and the underlying energetics of the organic semiconductor/electrode interface is an issue of primary concern for improving organic solar cell technologies. ...
Interplay of Optical, Morphological, and Electronic Effects of ZnO Optical Spacers in Highly Efficient Polymer Solar Cells
(Wiley, 2014-12-29)
Optical spacers based on metal oxide layers have been intensively studied in poly(3-hexylthiophene) (P3HT) based polymer solar cells for optimizing light distribution inside the device, but to date, the potential of such ...

The emission properties of hybrid halide perovskites are exploited to implement a stable and very low power operation waveguide optical amplifier integrated in a silicon platform. By optimizing its design with a poly(methyl ...
Diffusion and Monod kinetics model to determine in vivo human corneal oxygen-consumption rate during soft contact lens wear
(Elsevier, 2015-01)
Purpose:
We present an analysis of the corneal oxygen consumption Qc from non-linear models, using data of oxygen partial pressure or tension (pO2pO2) obtained from in vivo estimation previously reported by other authors. ...
High reduction of interfacial charge recombination in colloidal quantum dot solar cells by metal oxide surface passivation
