In the present work, we have studied the electron transport properties of single silicon nanowire using Semiconductor Module of COMSOLMultiphysics software. We construct a MSM (metal-semiconductor-metal) model where metal is selected as copper and semiconductor is taken as silicon. Silicon is doped with n-type impurity by increasing doping concentration. Further, the Schottky diodes formed at ...

The Levant has been repeatedly devastated by numerous earthquakes since prehistorical times. In order to understand the role of the dynamics of the water bodies in triggering the deformations in the Levant basin, a new theoretical thermo-mechanical model is constructed and extended by including a fluid flow component, in COMSOL Multiphysics simulation environment. The latter is modeled on a ...

This paper introduces an efficient model to describe energy dissipation in acoustic. When the propagation domain has hard wall boundary conditions only viscous and thermal losses happen and are completely described by the so-called Full Linearized Navier-Stokes model (FLNS) which is implemented in thermoacoutics interface using the COMSOL Acoustics Module. This model defined by a set of ...

The fixed beds have the advantage of large heat transfer area, for they are used in some designs of innovative nuclear reactors as the reactor FBNR. Inside of study of fixed beds is important to define the following parameters: flow minimum and velocity profile of cooling fluid, temperature profile of cooling fluid and the fuel elements.

Thermoelectric generators (TEG) use Seebeck’s effect to directly convert heat into electricity. TEG represent, therefore, a promising option for energy harvesting of waste heat, for example in car exhaust systems. To investigate the dynamic behavior of high temperature TEG, a test facility was numerically designed and finally constructed. Transient thermal simulations were performed in order to ...

INTRODUCTION Enhancement of a single-photon emission is a great demand in recent science and applications, including development novel class of light sources, encoded information transfer and biological imaging [1, 2, 3]. Fluorescence can be improved through excitation and emission enhancement. Improvement of these two processes can be realized by using the near-field enhancement accompanying ...

Methane detection and quantification is of great importance due to its natural abundance, potential to cause explosions and known greenhouse effect. Leak detection and concentration monitoring at source is highly challenging as CH4 is odorless and colorless. This can be performed mounting sensor network over a potential diffusion area. It requires optimal positioning of those sensor nodes to ...

Humanity is faced with an imminent energy crisis. The exponential growth of the human population and the consequential increase of the required energy on a global scale, the dramatic climate change and the exhaustibility of natural resources combined, force us to strive towards a sustainable future. The majority of energy is being produced by fossil fuels, carriers of high density of primary ...

Encapsulation is an established technique to protect sensitive materials from environmental factors such as oxygen and light. Nutritionally beneficial fatty acids like omega 3 fatty acids are susceptible to oxidation and are therefore encapsulated by drying an oil in water emulsion. It is assumed that the wall matrix, that is surrounding the lipid droplets, acts as an oxygen diffusion barrier. ...
