H. Van Cong

Abstract: In the n^+(p^+)-p(n) crystalline (X\equivGe, GaSb, CdTe or CdSe)-junction solar cells at 300K, due to the effects of impurity size, temperature, heavy doping, and photovoltaic conversion, we show that, with an increasing donor (acceptor)-radius r_{d\left(a\right)}, both the relative dielectric constant and photovoltaic conv [...] Read more.

Spectral shift caused by the Coriolis force

Nasko Elektronov, Zhivko Kushev

Abstract: The influence of the Coriolis inertial force, generated by orbital and spin motions of distant objects, on the energies of electromagnetic radiation during the exchange of photons between them is shown. The presence of a red or blue spectral shift arising from this influence has been demonstrated, which is fully consistent [...] Read more.

The carted quarks-based equations for the proton magnetic moment, its countless configurations and a supposed spin propelling engine.

Emmanuel Saucedo-Flores, Víctor Manuel Rangel-Cobián

Abstract: The proton magnetic moment is computed by considering its quarks generated currents based in orbit-like circuits created as they are carted along by its hauler spin. Equations are derived for each quark magnetic moment for two possible rotations modes; needed quarks configurations for each rotation mode to obtain the experi [...] Read more.

Parameterization of prompt neutron multiplicity for first-chance actinide photofission

Eugene V. Oleinikov, Alexander I. Lengyel, Oleg O. Parlag, Volodymyr T. Maslyuk, Igor V. Pylypchynets

Abstract: A parametric description of the dependence of the average number of prompt neutrons on the mass of fragments ν(A) from the actinides ( ²³⁵U and ²³⁸U) photofission has been developed for the range of energies of the first chance of fission (from thresholds of (γ,f) reaction to thresholds of (γ,nf) react [...] Read more.

Robust Advanced Sensor System for Determination of Volatile Organic Compounds (VOC)

Andreas Mangler, Julian Eise, Qi Zhang

Abstract: Nowadays more and more health risks are increasing. Beside the viruses, there are also other particles which have an impact on the human well-being. The so called volatile organic compounds (VOCs) are substances in the air and can be harmful in high concentrations. Therefore, the detection of VOC value is particularly important. [...] Read more.

H. Van Cong

Abstract: In our two previous papers [1, 2], referred to as I and II. In I, our new expression for the extrinsic static dielectric constant, \varepsilon\left(r_{d\left(a\right)}\right), r_{d\left(a\right)} being the donor (acceptor) d(a)-radius, was determined by using an effective Bohr model, suggesting that, for an increasing r_{d\ [...] Read more.
