Thermoelectric effects in quantum dots
We report a numerical renormalization-group study of the thermoelectric effect in the single-electron transistor (SET) and side-coupled geometries. As expected, the computed thermal conductance and thermopower curves show ...
Measurement of the electric energy storage capacity in solar thermoelectric generators’ energy harvesting modules
Reducing energy consumption is mandatory in self-powered sensor nodes of wireless sensor networks that obtain all their energy from the environment. In this direction, one first step to optimize the network is to accurately ...
Thermoeconomic model considering the environment impacts on thermoelectric power plants: Natural gas versus diesel
In this paper a comparative analysis of the environmental impact caused by the use of natural gas and diesel in thermoelectric power plants utilizing combined cycle is performed. The objective is to apply a thermoeconomical ...
Spark plasma texturing (SPT) of p-type [Ca2CoO3]0.62[CoO2] thermoelectric oxide
Hole-doped [Ca2CoO3]0.62[CoO2] (Co349) thermoelectric materials were densified and textured by spark plasma sintering (SPS) process. Thin pre-sintered Co349 lamellar samples were used to process textured monoliths. The ...
Aumento do rendimento de módulos fotovoltaicos com aproveitamento da energia térmica para geração termoelétrica de estado sólido
(Universidade Federal de Santa MariaBrasilEngenharia ElétricaUFSMPrograma de Pós-Graduação em Engenharia ElétricaCentro de Tecnologia, 2018-02-28)
The Sun is the main source of energy of the Earth’s atmosphere-ocean-land system. The technological society is highly depended on the solar energy converted and stored in reservoirs, such as oceans, rivers, winds, plants, ...
Computational Simulation Of Filtration Gas Combustion In A Porous Ceramic Annular Burner For Thermoelectric Power Conversion
A computational study on combustion in annular porous media and thermoelectric generation was performed. The reactor was composed of two types of porous media where flame stabilization was reached at the interface of them. ...
