Role of the Recombination Zone in Organic Light‐Emitting Devices

open access: yesAdvanced Materials, EarlyView.
This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

Are architectural traits at florewing stage relevant to account for yield advantage in hybrid rice? [PDF]

open access: yes, 2006
Yield advantage of hybrid rice over conventional inbred rice in tropical favorable environments, up to 15%, is commonly and simply attributed to higher biomass production due to higher seedling vigor and higher harvest index.

Competing roughening mechanisms in strained heteroepitaxy: a fast kinetic Monte Carlo study [PDF]

open access: yes, 2002
We study the morphological evolution of strained heteroepitaxial films using kinetic Monte Carlo simulations in two dimensions. A novel Green's function approach, analogous to boundary integral methods, is used to calculate elastic energies efficiently ...

Why Is the Mechanism Underlying the Chiral‐Induced Selectivity Effect Still Challenging?

open access: yesAdvanced Materials, EarlyView.
The chiral‐induced spin selectivity (CISS) effect is observed in many experimental configurations and for different materials. However, there are theoretical challenges in attempting to explain those results. A qualitative framework for explaining all the results is presented.

La souveraineté tribale des Indiens des Etats-Unis et le système fédéral américain

open access: yesNuevo mundo - Mundos Nuevos, 2008
American Native nations occupy a special niche in the political federal system. Could they be a model for nations elsewhere, also included in a larger system where they can figure as minorities although keeping some degree of autonomy? This article deals
