Wideband analytical equivalent circuit for coupled asymmetrical nonaligned slit arrays
(American Physical Society, 2017)
Microstructured metallic devices have been extensively studied because of their interesting properties for controlling the transmission, reflection, and absorption of electromagnetic waves. A very simple implementation is ...

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 ...

The Diverse Meteorology of Jezero Crater over the First 250 Sols of Perseverance on Mars
(Springer Nature, 2023)
NASA’s Perseverance rover’s Mars Environmental Dynamics Analyzer is collecting data at Jezero crater, characterizing the physical processes in the lowest layer of the Martian atmosphere. Here we present measurements from ...

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 ...

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 ...

Dry carbonate process for CO2 capture and storage: Integration with solar thermal power
(Elsevier Ltd, 2018)
Capture and sequestration of CO2 released by conventional fossil fuel combustion is an urgent need to mitigate global warming. In this work, main CO2 capture and sequestration (CCS) systems are reviewed, with the focus on ...

Calcium-Looping performance of mechanically modified Al2O3-CaO composites for energy storage and CO2 capture
(Elsevier B.V., 2018)
This work reports the Calcium-Looping (CaL) multicycle performance under energy storage and CO2 capture conditions of different Al-composites prepared by milling mixtures of nanoalumina and natural limestone powders. The ...

Hybrid-Phase-Transition FET Devices for Logic Computation
(IEEE, 2020)
Hybrid-phase-transition FETs (HyperFETs), built by connecting a phase transition material (PTM) to the source terminal of a FET, are able to increase the ON-to- OFF current ratio. In this article, we describe a comprehensive ...

Making metals transparent: A circuit model approach
(The Optical Society, 2016)
Solid metal films are well known to be opaque to electromagnetic waves over a wide frequency range, from low frequency to optics. High values of the conductivity at relatively low frequencies or negative values of the ...
