Dynamical effects in metalloprotein heterogeneous electron transfer
(Pergamon-Elsevier Science Ltd, 2020-03)
In this work we assess the influence of physiological viscosities on metalloprotein electron transfer reactions. To that end we investigated the direct electrochemistry of the copper proteins azurin and CuA adsorbed on ...
Electron transfer across anodic films formed on tin in carbonate-bicarbonate buffer solution
(Pergamon-Elsevier Science Ltd, 2005-01)
Impedance and steady-state data were recorded in order to study the kinetics of electron transfer between passive tin electrodes and an electrolytic solution containing the K3Fe(CN)6-K 4Fe(CN)6 redox couple. Film thickness ...
Gaussian Distribution of Electron Transfer Distance in Redox Terminated Self-Assembled Thiol Monolayers
(American Chemical Society, 2019-06-06)
A Gaussian distribution of tunneling distances due to different orientation populations in electrochemically active self-assembled monolayers composed of alkanethiols of different length has been assumed in a model which ...
Model for electron spin resonance in STM noise
(American Physical Society, 2014-02)
We propose a model to account for the observed ESR-like signal at the Larmor frequency in the current noise scanning tunnel microscope (STM) experiments identifying spin centers on various substrates. The theoretical ...
Electronic Fine Structure in the Electron-Hole Plasma in SrB6
(American Physical Society, 2000-07)
Electron-hole mixing-induced fine structure in alkaline earth hexaborides leads to lower energy (temperature) scales, and thus a stronger tendency toward an excitonic instability than in their doped counterparts (viz. ...
Metal Nanoparticle Enhancement of Electron Transfer to Tethered Redox Centers through Self-Assembled Molecular Films
(American Chemical Society, 2019-06)
Metal-nanoparticle-mediated electron transfer (ET) across an insulator thin film containing nanoparticles with attached redox centers was studied using electrochemical impedance spectroscopy. Specifically, a gold spherical ...
Electronic Structure of a Self-Assembled Monolayer with Two Surface Anchors: 6-Mercaptopurine on Au(111)
(American Chemical Society, 2018-05)
The electronic structure of aromatic and aliphatic thiols on Au(111) has been extensively studied in relation to possible applications in molecular electronics. In this work, the effect on the electronic structure of an ...
A density functional theory study of the electronic properties of Os(II) and Os(III) complexes immobilized on Au(111)
(American Chemical Society, 2007-01-08)
We present a density functional theory (DFT) study of an osmium polypyridyl complex adsorbed on Au(111). The osmium polypyridyl complex [Os(bpy)2(P0P)Cl]n+ [bpy is 2,2'-bipyridine, P0P is 4,4'-bipyridine, n = 1 for osmium(II), ...
Ballistic transport properties in pristine/doped/ pristine graphene junctions
(Academic Press Ltd - Elsevier Science Ltd, 2014-08)
We investigate the ballistic electron transport in a monolayer graphene with configurational averaged impurities, located between two clean graphene leads. It is shown that the electron transmission are strongly dependent ...
Single spin resonance driven by electric modulation of the g-factor anisotropy
(American Physical Society, 2019-12)
We address the problem of electronic and nuclear spin resonance of an individual atom on a surface driven by a scanning tunneling microscope. Several mechanisms have been proposed so far, some of them based on the modulation ...
