This paper evaluates the use of hydrated Portland cement as the raw material in the production of geopolymers. The silicon and aluminium oxides needed for the geopolymerization process were produced by the carbonation of ...

New biodegradable block copolymer networks were synthesized from methacrylate-terminated poly(L-lactide) (mLA) and polycaprolactone (mCL) macromers. This allowed the realization of a series of materials in which the macromer ...

[ES] Las condiciones medioambientales actuales han hecho necesario buscar y utilizar nuevas fuentes de energía, dando lugar a alternativas energéticas modernas como la biomasa. La energía de la biomasa es relativamente ...

[EN] Rice husk ash is one of the most widely studied biomass ashes used in pozzolanic addition. Given its lower silica content, rice straw ash (RSA) has been explored less often, despite the fact that, according to the ...

This work has been focused on the preparation and characterization of composite membranes with thickness between 19 and 97 mu m and containing Nafion(R) infiltrated into a porous mat obtained by electrospinning of an aqueous ...

The study of probes for CO sensing of a family of binuclear rhodium(II) compounds of general formula [Rh 2{(XC 6H 3)P(XC 6H 4)} n(O 2CR) 4-n]·L 2 containing one or two metalated phosphines (in a head-to-tail arrangement) ...

[EN] Soil stabilization using cementing materials is a well-known procedure for earth-based building blocks preparation. For the selected binding materials, innovation usually focuses on low carbon systems, many of which ...

[EN] This study evaluated the influence of partial replacement of Portland cement by rice husk ash (RHA) to enable the use of green coconut husk fiber as reinforcement for cementitious matrix. The use of highly reactive ...
