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 ...

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 ...

Transmission through stacked 2D periodic distributions of square conducting patches
(American Institute of Physics, 2012)
In this paper, we study the transmissivity of electromagnetic waves through stacked two-dimensional printed periodic arrays of square conducting patches. An analytical circuit-like model is used for the analysis. The model ...

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 ...

Alternate test of LNAs through ensemble learning of on-chip digital envelope signatures
(Springer, 2011-01-06)
This paper presents a novel and low-cost methodology for testing embedded Low Noise Amplifiers (LNAs). It is based on the detection and analysis of the response envelope of the Device Under Test (DUT) to a two-tone input ...

Improved nanopipelined RTD adder using generalized threshold gates
(Institute of Electrical and Electronics Engineers, 2011)
Many logic circuit applications of Resonant Tunneling Diodes are based on the MOnostable-BIstable Logic Element (MOBILE). Threshold logic is a computational model widely used in the design of MOBILE circuits, i.e. these ...

Fluidization of nanopowders: a review
(Springer Verlag, 2012)
Nanoparticles (NPs) are applied in a wide range of processes, and their use continues to increase. Fluidization is one of the best techniques available to disperse and process NPs. NPs cannot be fluidized individually; ...
