Fabrication of ultrafine and nanocrystalline WC-Co mixtures by high energy milling

Bonache Bezares, Victoria; Salvador Moya, Mª Dolores; Busquets Mataix, David Jerónimo; Segovia-López, Francisco (MANEY PUBLISHING, 2009)

[EN] In this work ultrafine and nanocrystalline WC-Co mixtures were obtained by low energy milling in planetary ball mill. The effect of the processing conditions on the reduction and distribution of the grain sizes and ...
Finely tuned temperature-controlled cargo release using paraffin-capped mesoporous silica nanoparticles

Aznar Gimeno, Elena; Mondragón Martínez, Laura; Ros-Lis, José Vicente; Sancenón Galarza, Félix; Marcos Martínez, María Dolores; Martínez Mañez, Ramón; Soto Camino, Juan; Pérez Payá, Enrique; AMOROS DEL TORO, PEDRO (Wiley-VCH Verlag, 2011-09-27)

Trapped: Mesoporous silica nanoparticles were loaded with a fluorescent guest and functionalized with octadecyltrimethoxysilane. The alkyl chains interact with paraffins, which build a hydrophobic layer around the particle ...
Inactivation kinetics and cell morphology of E.coli and S.carevisiae trated with ultrasound-assited supercritical CO2

Ortuño Cases, Carmen; Quiles Chuliá, Mª Desamparados; Benedito Fort, José Javier (Elsevier, 2014-08)

[EN] The inactivation kinetics of Escherichia coli (E. coli) and Saccharomyces cerevisiae (S. cerevisiae) cells in apple juice subjected to supercritical carbon dioxide (SC-CO2) assisted by high power ultrasound (HPU) ...
Influence of Deposition Potential on Structure of ZnO Nanowires Synthesized in Track-Etched Membranes

Pruna, Alina Iuliana; Pullini, Daniele; Busquets Mataix, David Jerónimo (Electrochemical Society, 2012)

Single-crystal ZnO nanowires long up to several microns were fabricated by one-step electrochemical deposition. A template-based process employing track-etched polycarbonate (TE-PC) membranes was used for this purpose. The ...
Influence of the preparation procedure on the catalytic activity of gold supported on diamond nanoparticles for phenol peroxidation

Martín González, Roberto; Navalón Oltra, Sergio; Delgado, Juan José; Calvino, José J.; Alvaro Rodríguez, Maria Mercedes; García Gómez, Hermenegildo (Wiley-VCH Verlag, 2011-08-16)

The catalytic activity of diamond-supported gold nanoparticle (Au/D) samples prepared by the deposition/precipitation method have been correlated as a function of the pH and the reduction treatment. It was found that the ...
Lead ion adsorption from aqueous solutions in modified Algerian montmorillonites

Zehhaf, A.; Benyoucef, A.; Berenguer, R.; Quijada Tomás, Cesar; Taleb, S.; Morallon, E. (Akadémiai Kiadó, 2012-12)

The adsorption of lead (II) ions on three Algerian montmorillonites (sodium, non-sodium, and acidic-activated) was studied. Transmission electron microscopy coupled with energy dispersive X-ray analysis, X-ray fluorescence ...
Mesoporous silica as multiple nanoparticles systems for inflammation imaging as nano-radiopharmaceuticals

Pascual, L.; Sancenón Galarza, Félix; Martínez-Máñez, Ramón; Barja-Fidalgo, T.C.; Da Silva, S.V.; Sousa-Batista, A.D.J.; Cerqueira-Coutinho, C.; Santos-Oliveira, R. (Elsevier, 2017)

[EN] Inflammation processes are difficult to manage, especially in certain diseases like cancer. The prognostic of the patient may change drastically during the therapy if an inflammation process occurs. In this direction ...
Microstructure and mechanical effects of spark plasma sintering in alumina monolithic ceramics

Alvarez-Clemares, I.; Borrell Tomás, María Amparo; Agouram, S.; Torrecillas, R.; Fernandez, A. (Elsevier, 2013-04)

The specific effects of spark plasma sintering (SPS) on the creep behavior, microstructure and mechanical properties of alumina monolithic ceramic were investigated. SPS introduces strains that concentrate at grain boundaries ...
