Unexpected electron spin density on the axial methionine ligand in CuA suggests its involvement in electron pathways
(Royal Society of Chemistry, 2020-01)
The CuA center is a paradigm for the study of long-range biological electron transfer. This metal center is an essential cofactor for terminal oxidases like cytochrome c oxidase, the enzymatic complex responsible for ...
Enhanced electron acceleration in aligned nanowire arrays irradiated at highly relativistic intensities
(IOP Publishing, 2020-01)
We report a significant enhancement in both the energy and the flux of relativistic electrons accelerated by ultra-intense laser pulse irradiation (>1 10 21 W cm-2) of near solid density aligned CD2 nanowire arrays in ...
Electron-impact multiple ionization of Ne, Ar, Kr and Xe
(Iop Publishing, 2014-05)
This work describes the multiple ionization cross sections of rare gases by electron-impact. We pay special attention to the high energy region (0.1?10 keV) where the direct ionization is a minor contribution and the ...
Exploiting electron storage in TiO2 nanoparticles for dark reduction of As(v) by accumulated electrons
(Royal Society Of Chemistry, 2013-05)
UV irradiation of an ethanolic sol of TiO2 nanoparticles produces a trapped Ti(III) centre and a noticeable Burstein shift. Direct evidence that the accumulated charges can drive the otherwise forbidden reduction of ...

Excitation of two interacting electrons as a plasmon-decay mechanism in proton-aluminum collisions
(American Physical Society, 2004-12)
Projectile-induced plasmon excitation in an electron gas has been studied by several authors who proposed two possible mechanisms for these plasmons to decay. In a previous work we considered one of these mechanisms in ...
Theoretical study of the charge transfer and electron emission in the scattering of He+ by an AlF3 surface
(American Physical Society, 2017-08)
Experimental results of electron emission from surfaces of aluminum fluoride impacted by keV noble gas ions (He+, Ne+, Ar+) show a high-energy structure that increases in intensity with ion energy in the case of He+ and ...
