Influence of ball milling on CaO crystal growth during limestone and dolomite calcination: Effect on CO2 capture at Calcium Looping conditions
(American Chemical Society, 2016)
The multicycle CO2 capture performance of CaO derived from the calcination of ball-milled limestone and dolomite have been tested under high temperature and high CO2 concentration environment for the first time. Here it ...

Miniaturised and harmonic-suppressed rat-race couplers based on slow-wave transmission lines
(Wiley-Blackwell, 2019)
In this study, a compact rat-race hybrid coupler with harmonic suppression based on slow-wave transmission lines (SW-TLs) is presented. Such artificial lines are implemented by periodic loading a host microstrip line with ...

Relevant influence of limestone crystallinity on CO2 capture in the Ca-looping technology at realistic calcination conditions
(American Chemical Society, 2014)
We analyze the role of limestone crystallinity on its CO2 capture performance when subjected to carbonation/calcination cycles at conditions mimicking the Ca-looping (CaL) technology for postcombustion CO 2 capture. The ...

Limestone calcination nearby equilibrium: Kinetics, CaO crystal structure, sintering and reactivity
(American Chemical Society, 2015)
In this work, we analyze limestone calcination kinetics at environmental conditions involving a CO2 partial pressure P close to the equilibrium pressure Peq by means of in situ X-ray diffraction (XRD) and thermogravimetric ...

Physically-insightful equivalent circuit models for electromagnetic periodic structures
(IOP Publishing Ltd., 2018)
In this presentation it will be discussed how to obtain analytical or quasi-analytical equivalent circuits to deal with periodic structures such as frequency selective surfaces and/or metasurfaces. Both the topology and ...

Effect of heat pretreatment/recarbonation in the Ca-looping process at realistic calcination conditions
(American Chemical Society, 2014)
Even though an increasing number of pilot-scale plants are demonstrating the potential efficiency of the Ca-looping technology to capture CO2 at a commercial level, a still standing matter of concern is the loss of carbonation ...

Fishnet Metamaterials - Rules for Refraction and Limits of Homogenization
(Optical Society of America, 2010)
The perfectly conducting stacked fishnet metamaterial is studied in this paper. The analysis is based on a combination of the mode matching method together with the generalized eigenvalue problem, and takes into account ...

The stability of a horizontal interface between air and an insulating liquid subjected to charge injection
(American Institute of Physics, 2014)
This paper presents the linear stability analysis of an interface between air and an insulating liquid subjected to a perpendicular electric field, in the presence of unipolar injection of charge. Depending on the ...

Flat Reflectarray That Generates Adjacent Beams by Discriminating in Dual Circular Polarization
(Institute of Electrical and Electronics Engineers, 2019)
One planar 18 \times 18 cm2 reflectarray prototype, capable of generating adjacent pencil beams with the orthogonal circular polarizations (CPs) in the Ka-band (19.2-20.2 GHz), has been designed, manufactured, and measured ...
