Maximal charge injection of a uniform separated electron pulse train in a drift space
Physical Review Special Topics. Accelerators and Beams, 2015 A charge sheet model is proposed to study the space charge effect and uniformity of charge separation of an electron pulse train in a drift space. An analytical formula is derived for the charge density limit as a function of gap spacing, injecting ...

Demonstration of stable long-term operation of a kilohertz laser-plasma accelerator
Physical Review Accelerators and Beams, 2020 We report on the stable and continuous operation of a kilohertz laser-plasma accelerator. Electron bunches with 2.6 pC charge and 2.5 MeV peak energy were generated via injection and trapping in a downward plasma density ramp. This density transition was

van der Waals driven anharmonic melting of the 3D charge density wave in VSe2
Nature Communications, 2021 The nature of the charge density wave transition in VSe2 is still debated. Here, the authors demonstrate that the transition is mainly driven by electron-phonon interactions, despite the presence of the Fermi-surface nesting, and that Wan-der-Waals ...

Decay of Electric Charge on Corona Charged Polyethylene
, 2007 In this paper, the surface potential decay of corona-charged low density polyethylene (LDPE) films has been investigated. It has been found that for the same sample thickness the faster decay occurs in the sample with a higher charging voltage.

Electrostatic Field Formed by Charge Separation in Antiparallel Magnetic Reconnection
The Astrophysical JournalThe Hall effect resulting from the decoupled motions between ions and electrons is a critical factor in modeling collisionless magnetic reconnection. It leads to the production of charge separation in the reconnection plane, generating the electrostatic ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

The electron density: experimental determination and theoretical analysis [PDF]
, 1997 Two related lines of research in experimental electron density determination are reported in this thesis. In the first case, the well-proven and popular multipole modeling technique is applied to three high resolution, single-crystal X-ray diffraction ...

The electronic charge densities in semiconducting layer and chain structures [PDF]
Journal of Physics and Chemistry of Solids, 1974 Abstract From calculations of the pseudo-wavefunctions the charge densities of the valence electrons in the semiconducting crystals SnSe 2 , PbI 2 , GaSe, Se and Te have been determined. The results are compared with the valence bond description of semiconductors which can thus be confirmed and refined. Insight is gained into the accommodation in the
