Electrostatically Driven Protein Adsorption: Charge Patches versus Charge Regulation
(American Chemical Society, 2018-12)
The mechanisms of electrostatically driven adsorption of proteins on charged surfaces are studied with a new theoretical framework. The acid-base behavior, charge distribution, and electrostatic contributions to the ...
Experimental measurements of charge separation under wet growth conditions
(John Wiley & Sons Ltd, 2018-05)
In this work we present the results of experimental measurements of the charge transferred to simulated graupel under wet growth conditions. The range of temperature was between −7 and −18 °C. The speeds of collision ...
Dual structure in the charge excitation spectrum of electron-doped cuprates
(American Physical Society, 2017-12)
Motivated by the recent resonant x-ray scattering (RXS) and resonant inelastic x-ray scattering (RIXS) experiments for electron-doped cuprates, we study the charge excitation spectrum in a layered t-J model with the ...
In-out asymmetry in the interaction of a charged projectile traversing a vacuum-metal interface in an oblique trajectory
(Elsevier Science, 2015-07-01)
In this work, we analyze the interaction of moving charged particles with plasmons in a semi-infinite material. For planar surfaces, and in the frame of a semiclassical dielectric formulation, we analyze the differences ...
Effect of charge-spin separation on the conductance through interacting low-dimensional rings
(Elsevier Science, 2009-10)
We calculate the conductance through Aharonov-Bohm chain and ladder rings pierced by a magnetic flux which couples with the charge degrees of freedom. The system is weakly coupled to two leads and contains strongly interacting ...
Effective treatment of charge and spin fluctuations in dynamical and static atom-surface interactions
(American Physical Society, 2009-12)
In this work we introduce a formalism that provides a good description of the correlated charge states of an atom interacting statically or dynamically with a metal surface, including realistic features of the atom-surface ...
Incommmensurability and unconventional superconductor to insulator transition in the hubbard model with bond-charge interaction
(American Physical Society, 2007-12)
We determine the quantum phase diagram of the one-dimensional Hubbard model with bond-charge interaction X in addition to the usual Coulomb repulsion U>0 at half-filling. For large enough X
State-selective charge exchange from Na(3s) and Na*(3p) by highly charged ions
(IOP Publishing, 2010-08)
State-selective charge exchange cross sections and momentum spectra are calculated for collisions of Xe18+ and Xe54+ ions with Na(3s) and Na*(3p) over the energy range of 0.1–10.0 keV/amu. The classical trajectory Monte ...
Symmetry‐Breaking Charge‐Transfer Chromophore Interactions Supported by Carbon Nanodots
(Wiley VCH Verlag, 2020-05)
Carbon dots (CDs) and their derivatives are useful platforms for studying electron-donor/acceptor interactions and dynamics therein. Herein, we couple amorphous CDs with phthalocyanines (Pcs) that act as electron donors ...
Thunderstorm graupel charging in the absence of supercooled water droplets
(John Wiley & Sons Ltd, 2016-07)
This study reports new measurements of the charge separation during ice crystal?graupel collisions in the absence of supercooled water droplets. Experimental measurements of the average charge acquired by a simulated ...
