Access charges, vertical separation, and lobbying [PDF]

open access: yesSSRN Electronic Journal, 2011
We examine how vertical separation affects the lobbying activities forthe access charge of essential facilities. First, when investigating a model where the number of new entrants is fixed, we find that vertical separation either increases or decreases ...

Understanding Photoinduced Symmetry- Breaking Charge Separation

open access: yesCHIMIA
Symmetry-breaking charge separation (SB-CS) is a photoinduced electron transfer reaction in which the chromophore acts as both the acceptor and the donor.

Spontaneous Separation of Charged Grains [PDF]

open access: yesPhysical Review Letters, 2007
In 1867, Lord Kelvin described an experiment in which two streams of water droplets were connected so that each stream amplified the charge on the second stream [W. Thomson, Proc. R. Soc. London 16, 67 (1867)]. We present here a complementary effect in flowing grains that spontaneously separates similar and well-mixed grains into two charged streams of

Ultrafast Charge Separation in Bilayer WS2/Graphene Heterostructure Revealed by Time- and Angle-Resolved Photoemission Spectroscopy

open access: yesFrontiers in Physics, 2021
Efficient light harvesting devices need to combine strong absorption in the visible spectral range with efficient ultrafast charge separation. These features commonly occur in novel ultimately thin van der Waals heterostructures with type II band ...

Spin-Charge Separation in Two Dimensions - A Numerical Study [PDF]

open access: yes, 1993
The question of spin-charge separation in two-dimensional lattices has been addressed by numerical simulations of the motion of one hole in a half-filled band. The calculations have been performed on finite clusters with Hubbard and t-J models.

Effect of bridge on energy transfer and photoinduced charge separation in perylene-diimide-naphthalene-bisimide-hexathiophene based donor-bridge-acceptor triads

open access: yesEPJ Web of Conferences, 2013
Femtosecond transient absorption spectroscopy is performed to assess bridge effects on energy transfer and charge separation in molecular junctions. A short, conjugated bridge can facilitate charge separation from both donor and acceptor, whereas in ...

Balancing charge generation and voltage loss toward efficient nonfullerene organic solar cells

open access: yesMaterials Today Advances, 2020
The inherently large exciton binding energy for photo-generated electron-hole pairs has hindered the charge generation and photons utilization in organic solar cells (OSCs) for decades, thereby constraining their performance to an inferior regime with ...

Cyclodextrins as modulators for separation of charged variants of mAbs by capillary zone electrophoresis

open access: yesJournal of Chromatography Open, 2021
Charge heterogeneity is a critical quality attribute for mAb-based therapeutics. Its characterization involves the identification of charge variant species in the final formulation. Capillary zone electrophoresis (CZE) is a valuable tool to assess charge
