Native vs photoinduced chemiluminescence in dimethoate determination

Catalá Icardo, Mónica; López Paz, José Luis; Choves Barón, Cristina; Pena Badena, A. (ELSEVIER SCIENCE BV, 2012)

The determination of dimethoate using either its native chemiluminescent (CL) properties or its photoinduced chemiluminescence obtained by irradiation with a 15W low-pressure mercury lamp was studied. Thereby, two flow ...
Photopolymerization as a promising method to sense biorecognition events

Peris Chanzá, Ernesto José; Bañuls Polo, María-José; Maquieira Catala, Ángel; Puchades, Rosa (Elsevier, 2012-12)

[EN] This work addresses the main topics related to the photopolymerization process to develop and to monitor the analytical signal derived from biorecognition assays. We review basic aspects of photopolymerization, together ...
Polyvinyl alcohol nanofiber reinforced Nafion membranes for fuel cell applications

Mollá Romano, Sergio; Compañ Moreno, Vicente (Elsevier, 2011-04-15)

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 ...
Reconstruction of the X-ray tube spectrum from a scattering measurement

Fernandez, Jorge E.; Scot, Viviana; Bare, Jonathan; Tondeur, François; Gallardo Bermell, Sergio; Ródenas Diago, José; Luca Rossi, Pier (Elsevier, 2012-07)

An inverse technique has been designed to unfold the x-ray tube spectrum from the measurement of the photons scattered by a target interposed in the path of the beam. A special strategy is necessary to circumvent the ...
Representation of planar motion of complex joints by means of rolling pairs. Application to neck motion

Page Del Pozo, Alvaro Felipe; De Rosario Martínez, Helios; Galvez Griso, Jose Antonio; Mata Amela, Vicente (ELSEVIER SCI LTD, 2011-02-24)

[EN] We propose to model planar movements between two human segments by means of rolling-without-slipping kinematic pairs. We compute the path traced by the instantaneous center of rotation (ICR) as seen from the proximal ...
Role of fibronectin in topographical guidance of neurite extension onelectrospun fibers

Mukhatyar, Vivek J.; Salmerón Sánchez, Manuel; Rudra, Soumon; Mukhopadaya, Shoumit; Barker, Thomas H.; Garcia, Andres J.; Bellamkonda, Ravi V. (Elsevier, 2011)

Bridging of long peripheral nerve gaps remains a significant clinical challenge. Electrospun nanofibers have been used to direct and enhance neurite extension in vitro and in vivo. While it is well established that oriented ...
Role of material-driven fibronectin fibrillogenesis in cell differentiation

Salmerón Sánchez, Manuel; Rico Tortosa, Patricia María; Moratal Pérez, David; Lee, Ted T.; Schwarzbauer, Jean E.; Garcia, Andres J. (Elsevier, 2011)

Fibronectin (FN) is a ubiquitous extracellular matrix protein (ECM) protein that is organized into fibrillar networks by cells through an integrin-mediated process that involves contractile forces. This assembly allows for ...
Secondary organic aerosol formation from the photo-oxidation of benzene

Borrás García, Esther Mª; Tortajada Genaro, Luis Antonio (Elsevier, 2012-02)

The production of condensate compounds from the degradation of benzene by OH radical chemistry was studied. Secondary organic aerosol (SOA) formation was investigated in the EUPHORE (European Photoreactor) simulation ...
Source analysis of fine and coarse particulate matter from livestock houses

Cambra López, María; Torres Salvador, Antonio Germán; Aarnink, André Johannes Antonius; Ogink, Nico W. M. (Elsevier, 2011-01)

The analyses of the different sources which can contribute to particulate matter (PM) emissions from livestock houses are essential to develop adequate reduction techniques. The aim of this study was to morphologically and ...
Specific detection of viable Listeria monocytogenes in Spanish wastewater treatment plants by Fluorescent In Situ Hybridization and PCR

Moreno Trigos, Mª Yolanda; Ballesteros, Lorena; García Hernández, Jorge; Santiago Cuéllar, Paula; González Pellicer, Ana; Ferrús Pérez, Mª Antonia (IWA Publishing, 2011-10)

Listeria monocytogenes detection in wastewater can be difficult because of the large amount of background microbiota and the presence of viable but non-culturable forms in this environment. The aim of this study was to ...
Study of the effects of the applied current regime and the concentration of chromic acid on the transport of Ni2+ ions through Nafion 117 membranes

Martí Calatayud, Manuel César; García Gabaldón, Montserrat; Pérez-Herranz, Valentín (Elsevier, 2012-12-23)

In the present work galvanostatic experiments are conducted with an electrodialysis cell in order to study the passage of Ni 2+ ions present in chromic acid solutions through a Nafion cation-exchange membrane. The competing ...
Sub-critical filtration conditions of commercial hollow-fibre membranes in a submerged anaerobic MBR (HF-SAnMBR) system: The effect of gas sparging intensity

Robles Martínez, Ángel; Ruano García, María Victoria; García Usach, Mª Francisca; FERRER, J. (Elsevier, 2012-06)

A submerged anaerobic MBR demonstration plant with two commercial hollow-fibre ultrafiltration systems (PURON®, Koch Membrane Systems, PUR-PSH31) was operated using municipal wastewater at high levels of mixed liquor total ...
Surface ECG organization time course analysis along onward episodes of paroxysmal atrial fibrillation

Alcaraz, Raul; Hornero, Fernando; Rieta, J J (Elsevier, 2011-07)

The complete understanding of the mechanisms leading to the initiation, maintenance and self-termination of atrial fibrillation (AF) still is an unsolved challenge for cardiac electrophysiology. Studies in which AF has ...
Temperature effect of tapered element oscillating microbalance (TEOM) system measuring semi-volatile organic particulate matter

Tortajada Genaro, Luis Antonio; Borrás García, Esther Mª (Royal Society of Chemistry, 2011)

The tapered element oscillating microbalance (TEOM) system is widely used to measure continuous particle mass concentrations in air quality networks. However, the semi-volatile aerosol material is lost under normal operation ...
