Bioavailability of heavy metals in soils amended with sewage sludge
Morera Luzán, María Teresa
; Echeverría Morrás, Jesús 
; Garrido Segovia, Julián José (Agricultural Institute of Canada, 2002)
Artículo / Artikulua 
The recycling of sewage sludge to agricultural land results in the slow accumulation of potentially toxic heavy metals in soils. A greenhouse experiment was conducted to determine the bioavailability of Cu, Ni, Pb and ... -
Effect of Cu substitution on the magnetic and magnetic induction heating response of CdFe₂O₄ spinel ferrite
Ghasemi, R.; Echeverría Morrás, Jesús ; Pérez de Landazábal Berganzo, José Ignacio ; Beato López, Juan Jesús ; Naseri, M.; Gómez Polo, Cristina (Elsevier, 2020)
Artículo / Artikulua
In this work, a comparative study of the effect of Cu on the structural, magnetic and magnetic induction heating response in CdFe2O4 spinel is presented. The ceramic nanoparticles (Cu1−xCdxFe2O4; 0 ≤ x ≤ 1) were synthesized ... -
Estrategias del alumnado de Educación Secundaria para estimar la densidad
Napal Fraile, María ; Echeverría Morrás, Jesús ; Zulet González, Amaia ; Santos Cervera, Leyre; Ibarra Murillo, Julia (Universitat Autònoma de BarcelonaUniversitat de València, 2018)
Artículo / Artikulua
La densidad, o concentración de materia, es un concepto muy relevante pero que genera muchas dificultades de comprensión. Para medir la competencia en la estimación de la densidad del alumnado de la ESO, se pasó un ... -
Fiber optic sensors based on hybrid phenyl-silica xerogel films to detect n-hexane: determination of the isosteric enthalpy of adsorption
Echeverría Morrás, Jesús ; Calleja, Ignacio; Moriones Jiménez, Paula ; Garrido Segovia, Julián José (Beilstein-Institut, 2017)
Artículo / Artikulua
We investigated the response of three fiber optic sensing elements prepared at pH 10 from phenyltriethoxysilane (PhTEOS) and tetraethylsilane (TEOS) mixtures with 30, 40, and 50% PhTEOS in the silicon precursor mixture. ... -
Mid-infrared spectroscopy (MIR) for simultaneous determination of fat and protein content in meat of several animal species
Lozano Saiz, María; Rodríguez Ulibarri, Pablo ; Echeverría Morrás, Jesús ; Beruete Díaz, Miguel ; Sorolla Ayza, Mario ; Beriain Apesteguía, María José (Springer, 2017)
Artículo / Artikulua
The aim of this research was to study the application of MIR spectroscopy as an alternative to conventional methods to determine fat and protein content. Samples of the main species used to produce meat products were ... -
Mobility of heavy metals in soils amended with sewage sludge
Morera Luzán, María Teresa; Echeverría Morrás, Jesús ; Garrido Segovia, Julián José (Agricultural Institute of Canada, 2001)
Artículo / Artikulua
Sewage sludges added to arable land can improve soil fertility and physical properties. However, the concentrations of heavy metals commonly found in sludges limits their application to soil. The purpose of this paper is ... -
Phenyl siloxane hybrid xerogels: structure and porous texture
Moriones Jiménez, Paula ; Echeverría Morrás, Jesús ; Parra, Bernardo; Garrido Segovia, Julián José (Springer US, 2019)
Artículo / Artikulua
The aim of this research is to investigate the effect of phenyltriethoxysilane (PhTEOS) and tetraethoxysilane (TEOS) molar ratios as silicon precursors on the structure and porous texture of xerogels. We have prepared ... -

Moriones Jiménez, Paula (2016)
Tesis doctoral / Doktoretza tesia
Esta investigación aborda la síntesis de materiales híbridos mediante proceso sol-gel utilizando diferentes condiciones de síntesis como el pH, temperatura y proporción precursor-disolvente obteniendo una amplia variedad ... -
Steering the synthesis of Fe3O4 nanoparticles under sonication by using a fractional factorial design
Echeverría Morrás, Jesús ; Moriones Jiménez, Paula ; Garrido Segovia, Julián José ; Ugarte Martínez, María Dolores ; Cervera Gabalda, Laura María ; Garayo Urabayen, Eneko ; Gómez Polo, Cristina ; Pérez de Landazábal Berganzo, José Ignacio (Elsevier, 2021)
Artículo / Artikulua
Superparamagnetic iron oxide nanoparticles (MNPs) have the potential to act as heat sources in magnetic hyperthermia. The key parameter for this application is the specific absorption rate (SAR), which must be as large as ... -
Strategies for fabrication of hydrogen peroxide sensors based on electrostatic self-assembly (ESA) method
Del Villar, Ignacio ; Matías Maestro, Ignacio ; Arregui San Martín, Francisco Javier ; Echeverría Morrás, Jesús ; Claus, Richard O. (Elsevier, 2004)
Artículo / Artikulua
An optical fiber sensor has been fabricated for detection of 5 M–0.1mM concentrations of hydrogen peroxide with a linear response. The deposition method used is electrostatic self-assembly (ESA) of polymer cationic and ... -
Tenderness of PGI "Ternera de Navarra" beef samples determined by FTIR-MIR spectroscopy
Beriain Apesteguía, María José ; Lozano Saiz, María; Echeverría Morrás, Jesús ; Murillo Arbizu, María Teresa ; Insausti Barrenetxea, Kizkitza ; Beruete Díaz, Miguel (MDPI, 2022)
Artículo / Artikulua
Understanding meat quality attribute changes during ageing by using non-destructive techniques is an emergent pursuit in the agroindustry research field. Using beef certified samples from the protected geographical indication ...
