<p dir="ltr">With a new perspective to electromagnetism based on the fact that photon particles have mass, we give novel hypothesis explain light dispersion. By applying geometric number theoretic method together with data analysis, calculate mass of single moving speed <i>c</i> be approximately 9.1×10^−47kg. Theoretically, it could serves universal unit especially for subatomic particles, because is lightest might imagined in universe. This point view has interesting...

In this research, effects of magnetic field strength (400, 500 and 600 mT) type water (distilled saline water) was studied on germination growth characteristic wheat seeds. Results showed that the intensity treated had significant The morphological properties plants were improved compared with controlled ones. Experimental results rate seeds by 400 mT using distilled highest amount (53.3%) it lowest (20%) for control groundwater. Distilled affected in groundwater resulted amounts root length...
In this letter, we investigated the behaviors of absorptive–dispersive properties weak probe light in a four-level InGaN/GaN quantum dot nanostructure. order to achieve wave functions and their corresponding energy levels mentioned nanostructure, Schrödinger Poisson equations must be solved self consistently for carriers (here electrons) dots. The enhanced refractive index with amplification can obtained via adjusting controllable parameters such as intensity, detuning relative phase applied...
In this study, the structural and physical properties of hinge-like Co2S3 Co2Te3 nanosheets are predicted using spin-polarized density functional theory. Our calculations show that ferromagnetic semiconductors antiferromagnetic metals in ground state, respectively, these dynamically thermodynamically stable. According to mean-field theory, have Néel temperature 933 K Curie 285 K. Also, unique such as significant total magnetic momentum (5.07 μB) high anisotropy energy (2.62 meV). The...
Carbon nanotube (CNT) growth on catalyst as a function of time, temperature, diameter the CNT, damping factor system, and type is investigated via theoretical analysis phonon vibration system. Simulations demonstrate that CNTs with larger grow lesser owing to higher factors CNT inertia. In addition, an optimum temperature for obtained specific catalyst. Finally effect also discussed. from theory are in good agreement reported experimental results. Keywords: growth, Optimum Catalyst, Van der...
In this paper, interactions of carbon monoxide (CO) and hydrogen sulfide (H2S) with doped decorated graphene were investigated by using density functional theory quantum-espresso packages. First all, impurity effects properties like adsorption mechanism, the more probable position, binding energy, bond length, Lowdin charge analyze state (DOS) have been determined then CO H2S calculated, a brief comparison other studies has done. All these lead to tuning electronic structure sheet impurities...
The growth rate of carbon nanotubes in chemical vapor deposition is simulated by using a theoretical analysis the phonon vibration system. Simulations demonstrate that with larger diameters smaller because higher damping factors and nanotube inertia. An optimum temperature for calculated on Fe catalyst. from theory are good agreement reported experimental results.
In this paper, we investigated the behaviors of absorptive-dispersive properties weak probe light based on quantum coherence and interference in a Landau-quantized graphene nanostructure driven by coherent pumping fields. The linear dynamical grapheme are discussed with reference to density matrix method perturbation theory. It is found that under certain conditions an appropriate selection parameters medium, absorption, dispersion group index can be controlled. Moreover, superluminal...
