Structural models of random packing of spheres extended to bricks: Simulation of the nanoporous calcium silicate hydrates
(Taylor & Francis, 2009)
Structure simulation algorithms of random packing of spheres and bricks have been developed. These algorithms were used to reproduce the nanostructure of the cementitious calcium silicate hydrates. The textural parameters ...

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. ...

The cluster model: A simulation of the aerogel structure as a hierarchically-ordered arrangement of randomly packed spheres
(Springer Nature, 2005)
A new structural model based on the premises widely used for describing the structure of aerogels has been introduced. These structures have been described as an assemblage of randomly-packed spheres in several ...

New method for carbon dioxide mineralization based on phosphogypsum and aluminium-rich industrial wastes resulting in valuable carbonated by-products
(Elsevier, 2017)
A new carbon mineralization method was designed based on a sequestration agent synthesised exclusively from industrial wastes. Phosphogypsum waste from the fertiliser industry was dissolved into caustic aqueous waste from ...

SANS study of hybrid silica aerogels under "in situ" uniaxial compression
(Springer Nature, 2008)
We have modified the inorganic silica network of aerogels with polydimethylsiloxane (PDMS), a hydroxyl-terminated polymer, to obtain an organic modified silicate (ORMOSIL). Reactions were assisted by high-power ultrasounds. ...

Structure of supercritically dried calcium silicate hydrates (C-S-H) and structural changes induced by weathering
(Springer Nature, 2013)
The nanostructure of supercritically dried calcium silicate hydrates was researched. This particular drying procedure was used to avoid nanostructure modifications due to conventional drying processes. Thus, in this study, ...

Fabrication of Porous Alumina Structures by SPS and Carbon Sacrificial Template for Bone Regeneration
(MDPI, 2022)
In this work, a procedure for fabricating porous alumina with the use of a carbon sacrificial template has been tested in order to optimize the fabrication of porous structures mimicking the porosity and mechanical properties ...

Procedure to use phosphogypsum industrial waste for mineral CO 2 sequestration
(Elsevier, 2011)
Industrial wet phosphoric acid production in Huelva (SW Spain) has led to the controversial stockpiling of waste phosphogypsum by-products, resulting in the release of significant quantities of toxic impurities in salt ...
