Ab initio cluster model study of geometry and bonding character of atomic nitrogen chemisorbed on the Cu(100) and Ag(100) surfaces
(1997-03-10)
Article
Accés restringit per política de l'editorialThe chemisorption of atomic nitrogen on the four-fold site Cu(100) and Ag(100) surfaces has been modeled by Cu5N, AgsN and Cu41N cluster models. For these clusters, ab initio Hartree Fock electronic wave functions have ... -
Chemisorption of molecular oxygen on Cu(1 0 0): a Hartree¿Fock and density functional study
(2001-02-20)
Article
Accés restringit per política de l'editorialThe interaction of molecular oxygen with the Cu(1 0 0) surface has been studied by using both Hartree–Fock and density functional methods in the framework of the cluster model approach. In this study, we have used the ... -
Cluster analysis of 4-day back trajectories arriving in the Barcelona Area, Spain, from 1997 to 2002
(2004-06)
Article
Accés obertStructural parameters for chemisorption of atomic carbon above a Si(100) surface have been obtained through a Si35H 32 cluster model and a MINDO/3 hamiltonian. The most stable position has been found to be the bridge one ... -
Cluster model study of the chemisorption of atomic carbon on Si(100) surfaces

Density functional study of atomic nitrogen and oxygen chemisorption on model clusters simulating the Cu and Ag ( 100) surfaces
(1997-05-23)
Article
Accés restringit per política de l'editorialDensity functional calculations which explicitly use the density gradient type nonlocal corrections to exchange and correlation are reported for the adsorption of atomic nitrogen and oxygen on the four-fold sites of (100) ... -
Optimización del control de la capacidad de adsorción de gases contaminantes en lechos secos
(Universitat Politècnica de Catalunya, 2016-07-25)
Projecte Final de Màster Oficial
Accés obertIn the process of storage, transportation and distribution of fruits, vegetables and flowers large amounts of gases such as volatile organic compounds (VOCs) and one in particular that is the ethylene produced, a plant ... -
Response surface methodology based on central composite design for simultaneous adsorption of rare earth elements using nanoporous calcium alginate/carboxymethyl chitosan microbiocomposite powder containing Ni0.2Zn0.2Fe2.6O4 magnetic nanoparticles: Batch and column studies
(2020-07-01)
Article
Accés obertIn this research paper, the utilization of the magnetic calcium alginate/carboxymethyl chitosan/Ni0.2Zn0.2Fe2.6O4 (CA/CMC/Ni0.2Zn0.2Fe2.6O4) was investigated for the simultaneous aqueous adsorption of Nd (III), Tb (III), ...
