Kinetics and cyclability of limestone (CaCO3) in presence of steam during calcination in the CaL scheme for thermochemical energy storage
(Elsevier, 2021)
In the present work, we explore the use of steam in the CaCO3 calcination step of a calcium looping process devised for integration into a thermochemical energy storage process (CaL-TCES). Steam produces a double benefit: ...

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 ...

Effect of Steam Injection during Carbonation on the Multicyclic Performance of Limestone (CaCO3) under Different Calcium Looping Conditions: A Comparative Study
(American Chemical Society, 2022)
This study explores the effect of steam addition during carbonation on the multicyclic performance of limestone under calcium looping conditions compatible with (i) CO2 capture from postcombustion gases (CCS) and with (ii) ...

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 ...

Molecular dynamics simulations of homogeneous solids using multi-layered structures
(IOP Publishing Ltd., 2008-07)
The main goal of this work is to model a homogeneous computer material with well-defined mechanical properties. To carry out the model material, an internal structure arranged in layers with different atom sizes is implemented ...
