Fractionation and fluxes of metals and radionuclides during the recycling process of phosphogypsum wastes applied to mineral CO2 sequestration
(Elsevier, 2015)
The industry of phosphoric acid produces a calcium-rich by-product known as phosphogypsum, which is usually stored in large stacks of millions of tons. Up to now, no commercial application has been widely implemented for ...

Intragranular carbon nanotubes in alumina-based composites for reinforced ceramics
(Springer Nature, 2019)
The traditional methods for the synthesis of reinforced alumina-based matrix composites with carbon nanotubes (CNTs) have presented serious difficulties for obtaining well-dispersed and homogeneously distributed CNTs within ...

Calcium silicates synthesised from industrial residues with the ability for CO2 sequestration
(SAGE Publications Ltd, 2014)
This work explored several synthesis routes to obtain calcium silicates from different calcium-rich and silica-rich industrial residues. Larnite, wollastonite and calcium silicate chloride were successfully synthesised ...

Technological proposals for recycling industrial wastes for environmental applications
(MDPI, 2014)
A two-fold objective is proposed for this research: removing hazardous and unpleasant wastes and mitigating the emissions of green house gasses in the atmosphere. Thus, the first aim of this work is to identify, characterize ...

Reinforced silica-carbon nanotube monolithic aerogels synthesised by rapid controlled gelation
(Springer Nature, 2018)
This work introduces a new synthesis procedure for obtaining homogeneous silica hybrid aerogels with carbon nanotube contents up to 2.50 wt.%. The inclusion of nanotubes in the highly porous silica matrix was performed by ...

Removal of basic yellow cationic dye by an aqueous dispersion of Moroccan stevensite
(Elsevier, 2013)
The aim of this study was to investigate the adsorption of basic yellow, a cationic dye, from aqueous solution by natural stevensite, with 104m2/g of specific surface area. The kinetics and the effects of several experimental ...

Recent insights into xerogel and aerogel mineral composites for CO 2 mineral sequestration
(Springer Nature, 2011)
Supercritically dried composites have already been analysed and proposed as carbon dioxide sequesters. However, the economical and energetic costs of the supercritical drying process had to be re-evaluated, and were ...

Hybrid aerogels and bioactive aerogels under uniaxial compression: an in situ saxs study
(2010)
The complex structure of hybrid organic/inorganic aerogels is composed by an inorganic phase covalently bonded to an organic chain forming a copolymer. Conventional hybrid aerogels were studied as well as bioactive hybrid ...

Flue gas adsorption by single-wall carbon nanotubes: A Monte Carlo study
(American Institute of Physics Publising LLC, 2016)
Adsorption of flue gases by single-wall carbon nanotubes (SWCNT) has been studied by means of Monte Carlo simulations. The flue gas is modeled as a ternary mixture of N2, CO2, and O2, emulating realistic compositions of ...

Absorption capacity, kinetics and mechanical behaviour in dry and wet states of hydrophobic DEDMS/TEOS-based silica aerogels
(Springer Nature, 2017)
This work is a new approach to the study of the structural, mechanical and absorption properties of hybrid organic/inorganic silica-based aerogels. Diethoxydimethylsilane and tetraethoxysilane have been used as precursors. ...
