Dynamic universe model’s SITA simulations can be used to solve many problems in physics, chemistry, Biology etc. The Universe Model is based on Newtonian gravitation and finds the total attractive force of all masses a combined way any single mass. This approach provides accurate results from level down Galaxy, Solar System, Earth, Electron, Energy, even Nanobio Particle levels. Our thinking ex...

Two organic compounds (SC-23=(E)-2-Cyano-3-(2,3-dimethoxyphenyl) acrylic acid and SC-25=(E)-2-Cyano-3-(2,5-dimethoxyphenyl) acrylic acid) involving methoxy groups as the electron donor and cyanoacrylic acid group as the electron acceptor have been investigated for dye sensitized solar cells. They shows a short-circuit current density (Jsc) of 2.08 and 1.81 mA cm-2, an open circuit voltage (Voc)...

X-ray absorption spectra can be collected in multiple ways, each exhibiting a different probing depth. The total electron yield signal contains contributions from primary, Auger and secondary electrons. We present data on the total electron yield probing depth at core level energies ranging from 77 to 929 eV. By coating materials with chromium overlayers, we find that the maximum probing depth ...

In this work, we model a radiofrequency discharge of hydrogenated silicon nitride in a capacitive coupled plasma reactor using Maxwellian and non-Maxwellian electron energy distribution function. The purpose is to investigate whether there is a real advantage and a significant contribution using non-Maxwellian electron energy distribution function rather than Maxwellian one for determining the ...

The design, construction, installation, and performance of the small angle rear tracking detector of the ZEUS experiment are described. The results on electron position measurement, electron energy correction , and background reduction at the rst level trigger are presented. The impact on the measurement of the proton structure function is discussed.

(Abstract) The ordinary Schrödinger equation with minimal coupling for a nonrelativistic electron interacting with a single-mode photon field is not satisfied by the nonrelativistic limit of the exact solutions to the corresponding Dirac equation. A Schrödinger-like equation valid for arbitrary photon intensity is derived from the Dirac equation without the weak-field assumption. The ”eigenvalu...

New data on the electron/muon ratio measured by the KASCADE extensive air shower experiment are presented. This ratio has been proven to be an important parameter for the determination of the mass of the primary particle. The electron and muon detector responses and reconstruction accuracies of the shower parameters have been studied in detailed simulations. Due to the extended lateral distribu...

We consider an electron in two dimensions submitted to a magnetic field and to the potential of impurities. We show that when the electron is confined to a half-space by a planar wall described by a smooth increasing potential, the total Hamiltonian necessarily has a continuous spectrum in some intervals in between the Landau levels provided that both the amplitude and spatial variation of the ...

Glossary Quantum dot device: nanoscopic electronic device resembling a transistor which incorporates a quantum dot as the central active element; sometimes also called single electron transistor. A quantum dot is an extremely small puddle of electrons which can be considered as an artificial atom since the confinement of electrons leads to quantized energy levels: the electrons form orbitals mu...
