Investigation of using bottom or fly pine-olive pruning ash to produce environmental friendly ceramic materials
The present study investigates the feasibility of using fly or bottom biomass ash as a partial replacement in the production of eco-friendly construction materials. The fly and bottom ashes from combustion of biomass (olive ...
Experimental and theoretical study of Co sorption in clay montmorillonites
(IOP Publishing, 2018-03)
Montmorillonite (MMT) clays are 2:1 layered structures which in natural state may allocate different hydrated cations such as M-nH2O (M =Na, Ca, Fe, etc) in its interlayer space. Depending on the capability for ion sorption, ...
Epoxy-silica/clay nanocomposite for silver-based antibacterial thin coatings: Synthesis and structural characterization
(Academic Press Inc Elsevier Science, 2017-08-18)
Development of new functional coatings in the field of health care, as antibacterial applications, deals with a straight control of the diffusive properties that rules the releasing of the active component. In this work, ...
Epoxy-silica/clay nanocomposite for silver-based antibacterial thin coatings: Structure and ionic mobility
(Springer, 2020-07)
A novel material was developed using sol-gel chemistry and an environmental-friendly grafting process of clay nanoparticles. In a previous work of our group, highly compact coatings had been generated using silicon alkoxides, ...
Polycaprolactone/organoclay biodegradable nanocomposites: Dissimilar tendencies of different clay modifiers
(VBRI Press, 2018-11)
In this work, biodegradable nanocomposites based on polycaprolactone (PCL) reinforced with 2.5, 5.0 and 7.5 wt.% of two different clays, a commercial organo-clay (Cloisite 20A, C20A) and a laboratory modified bentonite ...
