Atmospheric pressure plasmas are becoming relevant in local microbial deactivation and other combined effects of on living organisms. For this reason, our research was focussed optimisation atmospheric plasma jet (APPJ) parameters to complete the different bacteria strains a medium. Different helium APPJ treatments with discharge were used, such as input voltages gas flows. To better understand...

We present a quantum and classical theory of electronic devices with one–dimensional (1D) channels made of a single carbon nanotube or a semiconductor nanowire. An essential component of the device theory is a self–consistent model for electrostatics of 1D systems. It is demonstrated that specific screening properties of 1D wires result in a charge distribution in the channel different from tha...

The electron beam energy is one of the critical parameters of electron accelerators since it can affect the dose distribution inside the body or in products to be irradiated with a beam of energetic electrons. A device has been developed for monitoring small variations in the electron beam energy that is easy-to-use during an irradiation run. It involves measurement of currents (or charges) col...

The properties of static spherically symmetric black holes, which carry electric and magnetic charges, and which are coupled to the dilaton in the presence of a cosmological constant, Λ, are reviewed.

In this study we investigate the effect of atoms such as B, N, Ge and Sn on the optical and the electrical properties of capped (5, 0) zigzag carbon nanotube, using DFT calculation method. These elements were attached to the one end of the carbon nanotube. We considered four different structure designs as possible candidates for a p-n junction device. The electrical properties of these structur...
