Carbon-nitrogen coupling on Pt(111) and its relevance to the catalytic synthesis of HCN
(Facultad Experimental de Ciencias de la Universidad del Zulia, 2011)
Nanocomposite PAAm/methyl cellulose/montmorillonite hydrogel: Evidence of synergistic effects for the slow release of fertilizers
(2013-08-07)
In this work, we synthesized a novel series of hydrogels composed of polyacrylamide (PAAm), methylcellulose (MC), and calcic montmorillonite (MMt) appropriate for the controlled release of fertilizers, where the components ...

Porous silica matrix obtained from pyrex class by hydrothermal treatment: Characterization and nature of the porosity
(Amer Ceramic Soc, 2003-07-01)
A novel porous silica matrix has been prepared from Pyrex glass, using hydrothermal treatment under saturated-steam condition. This process makes it possible to obtain, in one step, a silica support formed of a homogeneously ...
Modification of the Chemisorption Properties of Epitaxial Delafossite CuFeO2 Thin Films by Substituting Fe for Ga in the Crystal Structure
(2018)
Films of CuFeO2 and CuFe0.75Ga0.25O2 were grown over sapphire substrates in high vacuum using a pulsed laser deposition technique. The films grew with rhombohedral delafossite structure and highly epitaxial in the c-direction. ...
