A Customizable Thermographic Imaging System for Medical Image Acquisition and Processing
(Institute of Electrical and Electronics Engineers, 2022)
A custom system has been developed for medical image acquisition and processing in both the visible and the infrared (IR) bands. Unlike some non-customizable commercial devices, this system can easily be adapted to different ...

Analytical theory of wave propagation through stacked fishnet metamaterials
(Optical Society of America, 2009)
This work analyzes the electromagnetic wave propagation through periodically stacked fishnets from zero frequency to the first Wood's anomaly. It is shown that, apart from Fabry-Perot resonances, these structures support ...

Large-scale high-temperature solar energy storage using natural minerals
(Elsevier, 2017)
The present work is focused on thermochemical energy storage (TCES) in Concentrated Solar Power (CSP) plants by means of the Calcium-Looping (CaL) process using cheap, abundant and non-toxic natural carbonate minerals. CaL ...

CO2 capture performance of Ca-Mg acetates at realistic Calcium Looping conditions
(Elsevier BV, 2017)
The Calcium Looping (CaL) process, based on the cyclic carbonation/calcination of CaO, has emerged in the last years as a potentially low cost technique for CO2capture at reduced energy penalty. In the present work, natural ...

Two-dimensional numerical analysis of electroconvection in a dielectric liquid subjected to strong unipolar injection
(American Institute of Physics, 2012)
Two-dimensional numerical simulations are carried out to examine the problem of transient electroconvection stability of dielectric liquids subjected to unipolar injection. The entire set of electrohydrodynamics equations ...

Droplet group production in an AC electro- flow focusing microdevice
(Springer, 2017-09)
We report the production of droplet groups with a controlled number of drops in a microfluidic electro-flow focusing device under the action of an AC electric field. This regime appears for moderate voltages (500-700 V ...
