The Dual Origin of the Terrestrial Atmosphere

, 2003
The origin of the terrestrial atmosphere is one of the most puzzling enigmas in the planetary sciences. It is suggested here that two sources contributed to its formation, fractionated nebular gases and accreted cometary volatiles.

Experimental Investigations of a Krypton Stationary Plasma Thruster

International Journal of Aerospace Engineering, 2013
Stationary plasma thrusters are attractive electric propulsion systems for spacecrafts. The usual propellant is xenon. Among the other suggested propellants, krypton could be one of the best candidates.

DLTS spectra of silicon diodes with p+-n-junction irradiated with high energy krypton ions

Modern Electronic Materials, 2016
p+-n-Diodes have been studied. The diodes were manufactured on wafers (thickness 460 μm, (111) plane) of uniformly phosphorus doped float-zone-grown single-crystal silicon.

UNTOLD BLACK HISTORY [PDF]

, 2017
Black people’s history in the past centuries has being portrayed as people that lack the acumen to build any civilization of its own. The knowledge of the Black history has so far being said to be crude or savage and do not have a place in civilization.

A Theoretical Compatible Investigation to Estimate the Electrical Conductivity in Weakly Ionized Plasma Gases

Ibn Al-Haitham Journal for Pure and Applied Sciences
The main goal of this work is to achieve an acceptable agreement between the obtained results and previously published results of the electrical conductivities of Krypton and Xenon weakly ionized plasma gases, which are strongly affected by the electron

Charge transfer to ground-state ions produces free electrons

Nature Communications, 2017
Slow electrons, which cause radiation damage, are efficiently produced by interatomic neutralization processes. Here, the authors show experimental evidence for the efficient neutralization of the ionic states produced in Auger decay, using large neon ...

Electron acceleration by a radially polarized laser pulse during ionization of low density gases

Physical Review Special Topics. Accelerators and Beams, 2011
The acceleration of electrons by a radially polarized intense laser pulse has been studied. The axial electric field of the laser is responsible for electron acceleration.
